@gnanam1990 @anandh8x @jatmn this is the split you asked for on #808. All checks green. Small enough to read in one sitting, which was the point: +487/-128 across 29 files, versus the +9077 it was hiding inside. Three independent changes, and they are genuinely independent, so feel free to take a position on one and ignore the others. The parts I would look at hardest, because they are where I would expect to be wrong: The full-auto offer state lives on the model across keypresses. A stale flag would turn a later innocent The network reclassification loosens what counts as egress, which is exactly where a sandbox quietly weakens. @gnanam1990 already checked this on #808 and confirmed
On the rename: the old Go constants and the old on-disk value are both kept as permanent aliases rather than migrated. That is not politeness, it is the fix for how I broke CI on #808: deleting a constant that in-flight work is using makes the merge someone else's problem. What this does not change: full-auto skips permission PROMPTS. The OS sandbox stays on and the write jail still holds. That is why it is not called "unrestricted", and why the warning text names prompts specifically rather than implying something broader. Cherry-picked onto |

Approving at 0311ffb9. This is the split I asked for on #808 — the permission-mode rename and the dev-server network reclassification lifted out of the Windows-principals PR into their own change. Thanks for doing it.
The permission-mode change is carefully built, and I checked the parts that would bite
The wire value changed, and the backward-compat is in the right place. PermissionModeUnsafe = "unsafe" became PermissionModeFullAuto = "full-auto", with PermissionModeUnsafe now a compile-time alias. The alias only keeps Go code compiling — it does nothing for a persisted or transmitted "unsafe" string, which no longer equals the constant. What actually saves that is NormalizePermissionMode mapping both "full-auto" and legacy "unsafe" to PermissionFullAuto, and it's called at engine.go:315 — inside Decide, right before risk classification and the allow/deny. That is the enforcement chokepoint, so however the mode string arrived (CLI, ACP, session replay, config), it's normalized at the one point that governs enforcement. A restored "unsafe" session is enforced as full-auto, correctly.
And the failure direction is safe. Anything NormalizePermissionMode doesn't recognize falls to PermissionModeAuto, and the TUI's advancePermissionMode folds unknown modes to Ask — both stricter. So a missed normalization anywhere is a downgrade, never an escalation. The legacyFullAutoPermissionMode comment makes the "visible downgrade beats silent one" reasoning explicit, which is the right call for a value that lives in user configs.
The arm/confirm gate genuinely prevents accidental full-auto. Full-auto isn't reachable by cycling — shift+tab from Ask arms an offer, and confirmUnsafePermissionMode commits only from a live offer that any other keypress clears. So the path is shift+tab → shift+tab (arm) → ctrl+g, and pressing shift+tab again while armed goes to Auto and drops the offer rather than confirming. I mutation-tested this rather than trust the read: removing the if !offered guard so confirm ignores the offer fails TestConfirmDoesNothingWithoutALiveOffer immediately (confirm with no offer from auto = full-auto, want unchanged). The security property is pinned.
CLI compat holds: --skip-permissions-unsafe and --full-auto are both accepted (exec_parse.go:23), and --auto resolves to PermissionModeFullAuto. Remaining "unsafe" strings in the tree are either code comments or import "unsafe", not user-facing.
The network change is the same one I verified on #808
Network and LocalServer are still set by independent checks (analyzer.go:193, 196), so a command that genuinely fetches keeps Network = true even if it also binds a port — no egress escape. The commands moved out of egress (npm run dev, vite, next dev, http.server, start/serve/dev/preview) only bind, and LocalServer preserves the inbound signal rather than dropping it. Correct and fail-closed, as before.
Verified
go build ./...andGOOS=windows go build ./...clean.internal/tui,internal/sandbox,internal/agentsuites green; the arm gate is mutation-tested as above.- The two
internal/clidoctor failures (TestRunDoctorConnectivityProbesProvider,…FormatsRedactedProviderDiagnostics) are pre-existing — they fail on untouchedmainand this PR touches no doctor/observability/connectivity file. - Feature runs against the real binary: macOS 7/7, Linux 7/7 (file writes, nested paths, sandbox refusal,
--add-dirgrants, control characters, specialist children,exec_command). Windows is green on the PR's own CI (Smoke (windows-latest)pass, 9m).
One scope note, not blocking
The PR is still two unrelated concerns in one — a TUI permission-mode rename and a sandbox command-classifier change; the title carries the "and." It's a large improvement over #808's four-in-one, and both halves are correct, so I'm not going to hold it up. But they'd be independently revertable as two PRs, and the network reclassification in particular is the kind of security-adjacent change that's easier to reason about — and to bisect later — on its own. Your call; flagging it rather than requesting it.
Clean work, and the arm gate is a genuinely thoughtful bit of security-UX.

Pushed fixes for the review. Two of the findings turned out to be bigger than they looked, and one of them was a hole in my own tests. The legacy-value finding was right, and wider than reported. The Go alias only covers callers that name the constant. It does not cover a mode that travels as a string, and three places do:
All three fail safe, which is why nothing broke loudly. Added On the test-panic finding: correct, and worse than described. Renamed the file, fixed the model construction, and added a repository-wide test that fails on any With those tests actually running, the paste/mouse gap was real. Probed it before fixing: armed the offer, sent a
One I am skipping: the Wording fixes for the retry reasons, the exec warning and the shell-escape notice are in. The exec warning now names both flag spellings, since one bool backs both and pointing someone at a flag they did not type is its own small bug. Verification: Sorry about the dismissed approval @gnanam1990, the push was unavoidable. Re-requesting. |

-
[P1] Preserve a host-reachable path for local preview servers
internal/sandbox/analyzer.go:208
Reclassifyingpython -m http.server, Vite, and package-manager dev commands as non-network suppresses the only permission path that grantsNetworkAllow, butLocalServerhas no execution-policy consumer. The default Linux sandbox consequently adds--unshare-net, so the listener is private to the sandbox namespace and the user's browser cannot reach it; macOS's(deny network*)rejects the bind outright. A normal request to start a preview now runs without a prompt but cannot provide the advertised local server. Keep a scoped approval/runner path for host-visible listening (or consumeLocalServerwith a suitable policy) and cover the real accessibility behavior. -
[P1] Do not trust package-script names as proof of no network access
internal/sandbox/analyzer.go:268
npm run dev(and the pnpm/yarn/bun equivalents) executes arbitrary workspacepredev/script/postdev hooks, yet this change clears its network classification solely from the requested script name. For example, a repository can makepredevupload secrets withcurl; on unelevated Windows the documented network isolation is only the per-command approval gate, so this now runs with real network access and without the former prompt. Keep package-manager script dispatch network-gated unless the resolved script can be safely analyzed; only direct known listener binaries should be eligible for the relaxed classification. -
[P2] Normalize the legacy mode before the TUI consumes it
internal/tui/model.go:865
The compatibility conversion happens inagent.Run, butnewModelcopies a persisted/rawPermissionMode("unsafe")unchanged. Since the deprecated Go constant now has the value"full-auto", this makes the TUI reject!shell escapes, publish a prompting peer identity, and select lower self-correction autonomy even though the ensuing agent run normalizes to full-auto. Normalize at the TUI boundary as well and add the regression case requested by the existing CodeRabbit review. -
[P2] Include the canonical flag in generated shell completions
internal/cli/completions.go:23
Both root andexeccompletion inventories retain only the deprecated--skip-permissions-unsafespelling. The new documented and parsed--full-autoflag therefore cannot be suggested or completed in bash, zsh, fish, PowerShell, or elvish. Add the canonical spelling to both inventories while retaining the alias.

I found issues that need to be addressed before this is ready.
Findings
-
[P1] Preserve a host-reachable sandbox path for local preview servers
internal/sandbox/analyzer.go:192
The new classification setsLocalServerbut removesNetwork, and no policy or runner code consumesLocalServer. Consequently the existing network approval path is skipped and the command is executed with the defaultNetworkDenyprofile: Linux isolates it in a network namespace and macOS applies(deny network*). A normalpython -m http.serverorviterequest now runs without a prompt but cannot expose a preview to the user's browser. Keep a scoped host-listener approval/profile path (and cover runner-level accessibility), or retain the network approval path. -
[P1] Do not infer no egress from a package-script name
internal/sandbox/analyzer.go:257
npm/pnpm/yarn/bunrun dev(and the other serving names) are now classified as non-network without resolving the package script or its lifecycle hooks.

[P2] Normalize the legacy mode before the TUI applies mode-specific behavior
internal/tui/model.go:870
newModelcopies a rawPermissionMode("unsafe")option unchanged, while the TUI now checks onlyPermissionModeFullAuto. Any TUI entry point supplied with the accepted legacy value therefore rejects!shell escapes, publishes a prompting peer identity, and selects low self-correction, even thoughagent.Runlater normalizes the same run to full-auto.

All five fixed at Both P1s were the same mistake in two places, which is worth saying plainly: Your package-manager half is the sharper one and I had no answer to it. The fix keeps the classification, because a scoped host-listener path will want it, and keeps the approval until that path exists. One line, since both findings flow through the same point. I rewrote the PRs own tests rather than flipping their assertions. The three P2s are done as described: Build, vet, gofmt clean and cross-compiled for windows, linux and darwin.

The completion-tree test still asserts only the deprecated--skip-permissions-unsafespelling for both the root andexeccontexts. Removing either newly added--full-autoentry fromcompletionRootwould therefore leave all completion tests green, even though the advertised flag would no longer be suggested. Assert--full-autoin both contexts alongside the compatibility alias. -

It falls through to--auto high, so the safety warning claims a flag was passed that the user did not supply.

@jatmn head is Permission prompts off, from a keypress the user did not intend as a confirmation.

I found issues that need to be addressed before this is ready. The first four are runtime defects; the final two are public-contract drift that remains unresolved at the current head.
Findings
-
[P1] Keep unparseable local-server commands on the network-approval path
internal/sandbox/risk.go:42
The normal AST path intentionally setsNetworkfor every recognizedLocalServer, because the current implementation has no scoped listener capability: a server still needs the existing network approval to bind accessibly, and package-manager scripts can perform egress before binding. The changedunparseableNetworkPatternremoves those same server forms, however. Once the POSIX parser rejects a command string that the invoked shell accepts—the analyzer explicitly identifies Windows command strings as a fallback case—AnalyzeCommandreports onlyTooComplex;Classifythen addsunparseable_commandbut nonetworkcategory, andEngine.Evaluateskips theNetworkDenyprompt. A Windowsnpm run devcommand using such syntax can therefore execute arbitrarypredev/devegress without the approval that its parseable equivalent receives.The root cause is that the fail-closed fallback was changed to describe the intended future
LocalServerdistinction rather than the current enforcement contract. Keep the fallback a conservative superset of network-sensitive plain-command classifications until a policy/runner consumer actually provides a separately scoped listener capability. Restore the direct server, package-manager serving, andpython -m http.serverpatterns, then add regression cases that force the AST parser to fail on Windows-shell syntax and assert bothunparseable_commandandnetworkrisk. -
[P1] Cancel the full-auto offer when deferred clipboard input arrives
internal/tui/model.go:1440
tea.PasteMsgclearsunsafeArmed, but the result of the right-click paste command does not. The sequence is: right-click startspasteFromClipboardCmd; while its OS-clipboard read is pending, Shift+Tab reaches the full-auto offer; the delayedclipboardReadMsginserts text throughroutePaste; then an ordinary Ctrl+G enters full-auto because the arm survived the intervening input transition. That silently disables permission prompts after the user has moved on from the confirmation offer.The root cause is that the transient consent state is canceled only in selected source-event branches, while deferred completions that mutate the same input state bypass those branches. Treat deferred clipboard delivery as a cancellation boundary before handling success, failure, or the image probe; audit the analogous asynchronous input producers (for example clipboard-image and dictation deliveries) using the same rule. Add a handler-level regression that schedules the clipboard result, arms the offer before delivery, delivers the result, and proves Ctrl+G no longer changes the mode.
-
[P2] Register specialist tools from the resolved full-auto mode
internal/cli/exec.go:250
--permission-mode full-autois accepted and resolves toPermissionModeFullAuto, the same effective mode as--auto highand--full-auto. Specialist registration runs before that resolution, though, andshouldRegisterExecSpecialistToolsonly checks raw--autoand the boolean full-auto flags. A directzero exec --permission-mode full-auto --list-toolstherefore omits Task/swarm tooling; the same full-auto run requested through the other entry points includes it. In practice this prevents the explicitly selected full-auto agent from delegating work.The root cause is two independent interpretations of permission selection: registration uses raw CLI fields while execution uses the resolved mode. Resolve the effective permission mode before deciding registry composition, or make the eligibility predicate consume that resolved value, while retaining the existing specialist-child and spec-mode exclusions. Cover every full-auto entry point in a list-tools regression so future aliases cannot create another unequal capability set.
-
[P3] Attribute the
full_autoalias correctly in the safety warning
internal/cli/exec.go:631
resolveExecPermissionModeintentionally accepts--permission-mode full_auto, but the subsequent warning-source switch recognizes onlyfull-auto,unsafe, andhigh. A command such aszero exec --permission-mode full_auto ...consequently warns that full-auto is active because--auto highwas passed, although that flag was never supplied. This is especially misleading because the warning explains why prompt-gated tools will run without approval.The root cause is that alias acceptance and user-facing attribution are maintained in separate, incomplete tables. Carry a normalized source classification through parsing, or use a neutral
--permission-modeexplanation for every accepted direct-mode alias; do not infer the source from a partial string list later in execution. Add a warning regression forfull_autoalongside the existing--auto high, canonical, and legacy-spelling cases. -
[P2] Align the local-server feature claim with the shipped behavior
internal/sandbox/analyzer.go:195
The title and PR description say local dev servers stop counting as network egress and no longer need network approval. The current implementation deliberately sets bothLocalServerandNetworkfor each recognized server; no policy or runner consumesLocalServer; andTestServingStillRequiresNetworkApprovallocks in that behavior. Python, Vite, and package-manager server commands therefore remain approval-gated, and no host-listener capability has shipped. The current text promises a behavior the implementation intentionally avoids because dropping the network gate would either make listeners unreachable under Linux/macOS isolation or permit unreviewed package-script egress on Windows.The root cause is description drift after the safer follow-up changed the implementation. Either implement the complete capability—classification, explicit policy decision, and platform runner support for host-reachable binding while preserving outbound egress controls—or narrow the title, description, and release-facing text to describe the current classification foundation. Do not leave the PR claiming the removed approval path until that end-to-end capability exists.
-
[P3] Finish the canonical full-auto vocabulary in CLI help and validation
internal/cli/app.go:1491
The newly documented root--full-autopath still emits validation errors naming--skip-permissions-unsafeand recommends the deprecated flag for one-shot runs. The exec help text likewise listsunsafeas the permission-mode value and says--auto highenables unsafe tools, despite acceptingfull-autoas the canonical mode. Users can therefore follow the advertised spelling and then be sent to its deprecated alias or documentation for a mode name the PR replaces.The root cause is a partial rename across multiple independently maintained user-facing strings. Audit help, usage/validation errors, warnings, examples, completions, protocol-visible labels, and documentation against one canonical vocabulary: present
full-autoas the mode and primary flag; mentionunsafeand--skip-permissions-unsafeonly where their compatibility acceptance is intentional. Add focused output assertions for the root and exec help/errors so a future cleanup cannot silently reintroduce deprecated-first guidance.

All six addressed at P1, the unparseable fallbackConfirmed before changing anything, and it reproduces exactly as you described: Every parseable spelling gets the gate and the Windows batch form loses it. You are right about the cause: I aligned the fallback with the analyzer's category NAMES rather than with what it actually flags for network, and the AST path sets The regression asserts both spellings of the same intent classify alike, and fails loudly if the parser ever learns the syntax rather than passing vacuously. P1, the deferred clipboard armSame shape as the blur gap from last round, and I should have audited for it then rather than fixing the one branch you named. Cleared before the branches, so a failed read and the empty-clipboard image probe are covered too, and on P2, specialist registrationThe mode is resolved before the registry is composed now, and the predicate consumes the resolved value, so any spelling that reaches full-auto gets the same tools. Safe to hoist because the resolver only parses the options it was handed, so Worth telling you: my first version of that test asserted on P3, the warning attributionRather than extend the list to four spellings, it echoes what was typed. Keeping acceptance and attribution in two tables is what drifted once already. Extracted to P2, the descriptionYou are right and this one is on me rather than the code. An earlier draft did remove the approval, the follow-up put it back, and the description kept describing the version that no longer ships. Title and section rewritten to describe the classification foundation and to say plainly that the gate stays, with both reasons it stays, and that a host-listener capability is the follow-up this is for.

[P1] Cancel the full-auto offer when a streaming dictation partial arrives
internal/tui/model.go:1503
sttPartialMsgupdates the composer throughhandleDictationPartialwithout clearingunsafeArmed, unlike the final transcription and other deferred-input deliveries. While streaming dictation is active, Shift+Tab can offer full-auto, the next partial transcript changes the input, and a later ordinary Ctrl+G still confirms full-auto because active dictation is not a blocking modal. That silently disables permission prompts after the user has moved on from the confirmation.The root cause is treating only selected deferred-input message types as cancellation boundaries. The safety property is broader: an offer is valid only until the next user-visible input transition, whether that transition is a keypress, paste, focus change, final transcript, or streaming partial. Clear
unsafeArmedbefore dispatchingsttPartialMsg, then extend the deferred-input regression to exercise a valid active streaming session, deliver a partial, and prove a subsequent Ctrl+G cannot enter full-auto without a fresh offer. Keep the reset at the shared message-dispatch boundary rather than relying onhandleDictationPartialcallers, so future partial-delivery paths inherit the rule. -
[P1] Keep the Windows
pyHTTP-server spelling on the unparseable network gate
internal/sandbox/risk.go:57
The AST path recognizespy -m http.serveras a local server and deliberately setsNetwork, but the changedunparseableNetworkPatternincludes onlypython,python2, andpython3. A Windows batch spelling that the POSIX parser rejects, such asif "%OS%"=="Windows_NT" (py -m http.server 8000) else (true), is therefore marked unparseable but receives nonetworkcategory or approval, unlike its parseable equivalent. On Windows, that removes the approval gate that protects both egress and the currently unsupported host-listener case.The root cause is maintaining the AST classifier and its fail-closed regex fallback as separate, incomplete program inventories. The fallback is explicitly meant to be a conservative superset of every command for which the AST path sets
Network; it must therefore include every Python launcher the analyzer accepts, not just the Unix-oriented names. Addpyto the Python-module branch and add paired parseable/unparseable cases for it toTestUnparseableFallbackKeepsNetworkForServingCommands. More generally, derive or table-test fallback coverage against the analyzer's recognized server launchers, so a new or platform-specific alias cannot silently weaken enforcement only when parsing fails.

before LocalServer gains a policy consumer.

[P3] Do not mark option-bearing Vite builds as local servers
internal/sandbox/analyzer.go:405
frameworkSubcommandRunsLocalServerdetermines the action with the generic
firstSubcommandhelper. That helper skips a flag token but does not know
whether the flag consumes its next token. Forvite --config custom.config.ts build, it returnscustom.config.tsinstead ofbuild;
the unknown-token path then assumes a bareviteinvocation and returns true.
The analyzer consequently reportsLocalServer=true(and, through the
additive branch,Network=true) even though Vite executes a production build
and binds no listener.The root cause is treating an option value as a positional subcommand. Make
framework command parsing option-aware—at least consume documented
value-taking Vite flags before selecting the subcommand—or use a conservative
result when the action cannot be determined. Preserve the bare-viteserver
case, but add regression coverage for--config <file> buildand another
value-taking option before each build-like action so the serving/building
distinction does not regress when this classification is later consumed.
Unsafe was reachable only via --skip-permissions-unsafe at launch, which is bad discoverability: the mode exists, works, and nothing in the TUI tells you so. It is now the third position in the shift+tab cycle, alongside auto and ask. What it is NOT is reachable by repeating a navigation key. Unsafe turns permission prompts off entirely, so shift+tab only ever OFFERS it; committing takes ctrl+g while that offer is live. Press shift+tab again instead and the offer is declined and the cycle continues to auto, so every mode stays reachable with shift+tab alone. The offer lives on the model across keypresses, and that is the part worth being careful about: a stale flag would turn a later innocent ctrl+g into a silent drop into unsafe. So it is cleared unconditionally at the top of the key handler and re-armed only by the shift+tab branch. Forgetting a path therefore cancels the offer rather than leaving it live, which is the harmless direction to be wrong in. Tests drive the real handler for eight different cancelling keys and assert the consequence, not just the flag. ctrl+g is guarded in the case expression rather than the body, so without a live offer the key is not consumed at all and falls through to whatever would normally handle it. That is what stops it being a standalone shortcut into unsafe, and there is a test that presses it repeatedly from every other mode. Leaving unsafe stays one press and is never gated. Getting stricter should not need confirming. Returning to auto from ask now costs two presses, since it passes through the offer. That is inherent to a third position in a cycle rather than a regression, and TestShiftTabCyclesPermissionMode was updated to walk the whole loop rather than assume two positions. An earlier draft of this had the second shift+tab commit unsafe, which silently removed ask -> auto from the cycle entirely. TestPermissionModeCycleNeverReaches UnsafeOnItsOwn walks the full loop and asserts every mode stays reachable, so that cannot come back unnoticed.

`python -m http.server` was denied with "network access requires approval". Serving files out of the workspace on a local port is not reaching out, and treating it as egress made the single most common thing an agent is asked to do while building something stop for an approval that protected nobody. The analyzer already had a localServerPrograms map sitting beside networkPrograms, but commandUsesNetwork returned true for it anyway, so the distinction had been drawn and never acted on. It is acted on now: AnalysisResult carries LocalServer separately, so the information is preserved rather than dropped, and a caller that does care about inbound can still see it. Covers the same set consistently. `next dev` and `npm run dev` are the same intent, so classifying one as binding and the other as fetching would have left users hitting exactly the same wall through the other door. Both are LocalServer now, across npm, pnpm, yarn and bun, as a direct subcommand and behind `run`. What still counts as network is unchanged: install, add, ci, create, publish, login, exec, and every fetching program. `npx http-server` in particular stays network, because npx downloads the package when it is missing; the test caught that when a first pass flipped it, which is why the bind-versus-fetch pairs are now pinned side by side in the table. The unparseable fallback regex is updated to agree. Left alone it would have flagged an obfuscated dev server for network while the same command written plainly did not, which is the kind of inconsistency that is very hard to explain to whoever hits it. Being honest about the edge: some of these touch the network incidentally, and `npm run dev` may install first. The claim is narrow, that BINDING is not EGRESS, not that dev tooling is inert. Anything that actually fetches still matches through its own program or subcommand. Origin-Session: local-c962d7 | Claude Code | 5 prompts Origin-Snapshot: 3bb420a0a97b
"unsafe" was a judgement rather than a description, and it sat oddly beside auto and ask. full-auto says what the mode does and reads as the obvious third step: ask, auto, full-auto. Not "unrestricted", which was the other candidate and is factually wrong. This mode turns off permission PROMPTS. The OS sandbox stays on, the write jail still holds, and a label implying nothing restrains the agent would be wrong in the dangerous direction. The on-disk value changes to "full-auto" and "unsafe" is accepted permanently as an alias rather than migrated. That value lives in user configs and in scripts, and a session silently falling back to auto because its saved mode no longer parsed would be a confusing downgrade rather than a visible error. --full-auto is the new flag; --skip-permissions-unsafe keeps working and is documented as the deprecated spelling. The exec warning names "the full-auto flag" generically, because either spelling reaches it and the bool does not record which was typed: claiming --full-auto when the caller passed the old one would be a small lie in a warning, which is the wrong place for one. The warning also says "prompt-gated tools run without approval" rather than anything broader, for the same reason the mode is not called unrestricted. What deliberately does NOT change is the colour. The name can be calm; the indicator should not be, so full-auto keeps the alarm style in the status bar and the ctrl+g confirm gate is untouched. The Go "unsafe" package is imported in fifteen files here, so the rename was done by identifier token only and the imports were verified intact afterwards rather than assumed.

The rename broke CI, and it broke it in the merge rather than on the branch: this branch is ten commits behind main, CI builds the merge, and newer main code still references PermissionModeUnsafe and PermissionUnsafe. Deleting a constant that other work is actively using turns an ordinary merge into a compile failure for whoever merges second. Both old names are restored as deprecated aliases of the full-auto constants. Same value, so behaviour is identical, and code on either side of the rename compiles. My local check missed this because `go test ./internal/...` returned "ok (cached)" for internal/agent, and a cached result cannot catch a compile error. Verified this time with -count=1 and against an actual trial merge with origin/main rather than the branch alone. Origin-Session: local-c962d7 | Claude Code | 5 prompts Origin-Snapshot: 3bb420a0a97b
The rename kept a Go alias for PermissionModeUnsafe, which covers callers that name the constant. It does not cover a mode that moves as a string, and several do, so those paths went on comparing against "unsafe" and stopped matching. Three places were affected: - swarm permissionRank did not rank "full-auto", so it scored 0, the strictest tier. A full-auto parent clamped its members harder than an ask parent. - specialist specialistAutonomy did not match it either, so a full-auto parent's specialists dropped to read-only "low" autonomy. - the agent loop compares Options.PermissionMode directly, so a caller passing the old spelling got prompts instead of full-auto. All three fail safe, which is why nothing broke loudly. Added agent.NormalizePermissionMode and applied it at the single point the loop reads the mode off Options, and taught the swarm and specialist constants both spellings. Their existing tables only listed "unsafe", which is exactly how the rename passed review. Separately, permission_mode_arm_test.go was never compiled. Go read the trailing "_arm" as a GOARCH constraint and excluded the file from every amd64 build, so the five tests covering the shift+tab full-auto offer had never run, locally or in CI. Two panicked once they did. The file is renamed, the model construction fixed, and a repository-wide test now fails on any _test.go whose name ends in a GOOS/GOARCH token without an explicit build tag. With those tests actually running, the offer gate had a real hole: unsafeArmed was cleared only in the key handler, so a paste or a mouse click left the offer live and a later ctrl+g committed full-auto with nobody having accepted it. Paste and deliberate mouse actions now cancel it. Passive motion does not, since terminals stream motion while tracking is on and cancelling on a twitch would make the confirm key unreachable. Also: commandRunsLocalServer matched on program name alone, so "next build" and "vite build" claimed to bind a port while compiling. Nothing reads the flag yet, which is why it could be wrong quietly. Fixed to require a serving subcommand, falling back to bare-invocation behaviour when firstSubcommand lands on an option value rather than a subcommand. Remaining wording fixes name full-auto rather than unsafe in the retry reasons, the exec warning, and the shell-escape notice.

The rebase renamed nextPermissionMode to advancePermissionMode, and main's plan-mode test still called the old name, so internal/tui did not build. Also asserts the second return value. Plan must never carry a full-auto OFFER either, or two presses from Plan would reach the mode that turns permission prompts off entirely, starting from the one mode that promises no mutation.

…onical mode All five of jatmn's findings. The two P1s were the same mistake in two places: the LocalServer classification was treated as a REPLACEMENT for Network when nothing consumes it. No policy or runner code reads LocalServer, so classifying a serving command as local-only granted it no host listener; it only removed the network approval it used to get, and the command then ran under the default deny profile. On Linux that is a network namespace and on macOS (deny network*), so `python -m http.server` and `vite` started with no prompt and could not serve a preview to the operator's browser. The package-manager half is the sharper one. `npm run dev` is matched by SCRIPT NAME, and the repository decides what `dev` and `predev` actually do; either can curl before anything binds a port. On Windows the approval gate IS the network protection, so inferring no-egress from a name lets that egress run unprompted. LocalServer is now additive: the classification stays, because a scoped host-listener path will want it, and the approval path stays until that path exists. One line covers both findings, since both flow through the same classification. The PR's own tests asserted the premise being corrected, so they were rewritten rather than flipped: building still counts as no egress, serving now asserts it keeps BOTH the LocalServer classification and the network approval, and the table rows moved with it. The three P2s: resolveExecPermissionMode accepted only the deprecated `unsafe`, so `--permission-mode full-auto` failed usage validation before NormalizePermissionMode was ever reached, while the warning code already had an unreachable full-auto branch. It now accepts the canonical spelling and keeps unsafe as the alias, and the usage text names full-auto. newModel copied the raw mode through while the TUI tests only for PermissionModeFullAuto, so an entry point handed the accepted legacy value rejected ! shell escapes, published a prompting peer identity and chose low self-correction, even though agent.Run normalized the same run to full-auto. One value, two behaviours, decided by which layer looked at it. It is normalized at the TUI boundary now. Both completion inventories listed only --skip-permissions-unsafe, so no generated shell script could suggest the documented --full-auto. Both now carry the canonical flag alongside the deprecated alias. Origin-Session: local-c962d7 | Claude Code | 5 prompts Origin-Snapshot: 3bb420a0a97b

…red-input arm Five findings from review. The unparseable fallback lost the serving forms on the reasoning that they bind rather than fetch. The AST path sets Network for every recognized LocalServer anyway, deliberately, because nothing consumes LocalServer yet and `npm run dev` is matched by script name where the repository decides what dev and predev do. So dropping them did not align the two paths, it split them: the POSIX parser rejects Windows shell syntax the invoked shell accepts, and if "%OS%"=="Windows_NT" (npm run dev) else (npm start) came back parsed=false network=false while every parseable spelling got network. That is the approval gate disappearing on the platform where it is the only egress control. Restored as a superset, with a regression that asserts both spellings of the same intent classify alike and fails loudly if the parser ever learns the syntax. tea.PasteMsg cancels the full-auto offer, but a right-click paste does not arrive that way: it starts a clipboard read, and shift+tab can reach the offer while that read is in flight. The delayed delivery inserted text and left the arm alive, so an ordinary ctrl+g afterwards turned permission prompts off with the user several actions past the confirmation. Cleared before the branches, on the image delivery too, and on transcribed dictation for the same reason. Specialist registration read the raw CLI fields while execution read the resolved mode, so `--permission-mode full-auto` composed a registry without Task and swarm tooling while `--auto high` and `--full-auto` composed one with it. The mode is resolved before the registry now and the predicate consumes it, so a new alias cannot create another unequal capability set. The full-auto warning matched the typed --permission-mode value against three spellings while the resolver accepts four, so `--permission-mode full_auto` was told --auto high was responsible. It echoes what was typed instead of matching a list that has already drifted once. Help and validation text still led with the deprecated spelling: --permission-mode listed "unsafe" as its value, --auto high was described as enabling "unsafe tools", and the root-flag errors named --skip-permissions-unsafe. All now present full-auto as the mode and the primary flag; the deprecated alias stays where its compatibility is the point.

… the network fallback from the analyzer Two findings, both follow-ons to fixes I made last round. A streaming dictation partial did not cancel the full-auto offer. The final transcript did, and my note there said starting dictation is a keypress that already clears the arm, which does not cover this: the offer can be armed AFTER dictation is running, the next partial rewrites the composer, and active dictation is not a blocking modal, so an ordinary ctrl+g still confirmed with the user several actions past the confirmation. Cleared at the dispatch boundary rather than inside handleDictationPartial, so a future partial-delivery path inherits the rule. The regression drives a genuinely live session and fails if the partial never reaches the composer, so it cannot pass on a session-mismatch early return. The unparseable network fallback is meant to be a superset of everything the AST path flags, and it was maintained as a separate inventory, so it drifted. The analyzer accepts "py" as a Python launcher and the regex listed only python, python2 and python3: py -m http.server 8000 parsed=true network=true if "%OS%"=="Windows_NT" (py -m http.server 8000) else (..) parsed=false network=false if "%OS%"=="Windows_NT" (python -m http.server ...) else .. parsed=false network=true On Windows that approval IS the egress control. Rather than adding the alias and leaving two lists to drift again, the launchers are one named inventory the analyzer uses at both call sites, and the fallback test iterates it, so a launcher added there fails immediately if the regex does not cover it.

… at any arity Raised by CodeRabbit. Skipping flags is not enough, because it does not skip the words they CONSUME: `npm --prefix ./web install` resolved to "./web", the option's VALUE, and stopped being recognised at all — so a command genuinely fetching from the network lost the approval its plain spelling gets. The first fix offered a fixed window of two positions. That covers exactly ONE value-taking option, and a second walks straight past it. Measured before this change: npm --prefix ./web install -> network (correct) npm --prefix ./web --loglevel warn install -> NOT network npm --registry https://r.test --prefix ./web install -> NOT network pnpm -C ./web --filter web add left-pad -> NOT network All four genuinely fetch. ADJACENCY DECIDES NOW, because it is the actual grammar: an option can only consume the word immediately after it. Every leading operand sitting right after a flag might be that flag's value, so each opens another position; the first operand NOT preceded by a flag cannot be anyone's value, and the window closes there. The arity is counted rather than assumed, and no option is ever named — which was the point of not enumerating them, since that is four tools each free to add one. The run has to be CONTIGUOUS, not a count of flags anywhere in the line. Counting every flag lets TRAILING options widen the window back over words they have nothing to do with, and three cases flip to false positives when it does: npm run --grep foo --tag dev -> network AND localServer npm run test --reporter x --filter dev -> network npm run build --a x --b start -> network The false positives the old cap protected against are unaffected, and for a stronger reason than the cap gave: `npm run build --workspace dev` and `npm run test -- --grep start` put an unflagged operand FIRST, so the window is one position wide however many flags follow. The cap held only because two happened to be short enough. Tested as a PROPERTY rather than a list: each flagged form is paired against its unflagged baseline, so a change that shifts both still fails. Eight pairs, the "="-joined forms and repeated flags included. Two mutations, each caught — restoring the fixed window mis-classifies five, dropping the contiguity requirement widens three. Also from a verification pass: The doc comment claimed the cap at two was justified purely by argument-position false positives and never said a second value-taking option defeated it. It now describes what ships. `npm --prefix dev install` reads a directory named "dev" as a script name. Pinned rather than fixed: the ambiguity is the point of the window, Network is already correct because the install really does fetch, and LocalServer only implies Network — so the union is conservative in the safe direction. An earlier note justified leaving internal/tui/session.go unnormalised by saying the value feeds transcript rendering and the render cache. It feeds only the cache fingerprint — grepping every reader of PermissionMode in that package returns render_cache.go and nothing else — so the tradeoff described did not exist. It is normalised now, and two spellings of one mode no longer evict the cache for nothing. The ACP tests asserted on ConfigOptions[1], a magic index that would move onto a different option if the advertised order changed. They select by ID. Rebased onto ad34dc8. Pre-existing here and on main: TestRunDoctorFormatsRedactedProviderDiagnostics and TestRunDoctorConnectivityProbesProvider exit 3 in this environment.

Four commits lifted out of #808, where they did not belong. @gnanam1990 blocked that PR on scope and he was right: #808 rewrites Windows write-jail semantics, and burying a permission-mode rename and a network reclassification inside it makes the security-relevant core harder to review on its own.

The permission mode gains a third position
unsafemode existed and worked, but was reachable only through--skip-permissions-unsafeat launch, so nothing in the TUI told you it was there. It is now the third position in the shift+tab cycle.What it is NOT is reachable by repeating a navigation key. shift+tab only ever OFFERS it; committing takes
ctrl+gwhile that offer is live. Press shift+tab again instead and the offer is declined and the cycle continues, so every mode stays reachable with shift+tab alone.The offer lives on the model across keypresses, which is the part worth care: a stale flag would turn a later innocent
ctrl+ginto a silent drop into full-auto. So it is cleared unconditionally at the top of the key handler and re-armed only by the shift+tab branch. Forgetting a path cancels the offer rather than leaving it live, which is the harmless direction to be wrong in. The tests drive the real handler with eight different cancelling keys and assert the consequence, not just the flag.An earlier draft had the second shift+tab commit full-auto, which silently removed
ask -> autofrom the cycle. There is now a test that walks the whole loop and asserts every mode stays reachable, so that cannot come back unnoticed.unsafebecomesfull-auto"unsafe" was a judgement rather than a description and sat oddly beside auto and ask.

Local dev servers are classified separately, and still need network approval
Narrowed from what this section used to claim. An earlier draft of this branch did remove the network approval for serving commands, the follow-up put it back, and the description kept describing the version that no longer ships.
What ships is the classification foundation.
AnalysisResultcarriesLocalServerseparately, so the distinction between binding a port and reaching out is preserved rather than collapsed. The analyzer already had alocalServerProgramsmap besidenetworkProgramsandcommandUsesNetworkreturned true for it anyway, so the distinction had been drawn and never acted on.What does NOT ship is dropping the approval.
Networkis still set for every recognizedLocalServer, on purpose, andTestServingStillRequiresNetworkApprovalpins it. Two reasons:LocalServeryet. No policy or runner reads it, so classifying a serving command as local-only would not grant it a scoped host listener, it would only remove the approval it used to get. The command then runs under the default deny profile, a network namespace on Linux and deny-network on macOS, sopython -m http.serverandvitewould start without a prompt and be unable to serve anything to the operator.npm run devis matched by SCRIPT NAME, and the repository decides whatdevandpredevactually do; either can fetch before a port is bound. On Windows the approval gate IS the egress protection, so inferring "no egress" from a name there lets that egress run unprompted.So
python -m http.server, Vite, and the package-manager serving commands remain approval-gated exactly as before. Coverage is consistent across npm, pnpm, yarn and bun, direct and behindrun, becausenext devandnpm run devare the same intent and classifying one differently would be arbitrary.The unparseable fallback is kept a superset of this for the same reason: the POSIX parser rejects Windows shell syntax the invoked shell accepts, and a serving command written in a spelling it cannot read must not lose the gate its parseable form receives.
A host-listener capability is the follow-up this foundation is for: classification, an explicit policy decision, and platform runner support for reachable binding while outbound egress stays controlled. Until that exists end to end, the gate stays.
