For predictable actions with already observed targets, mcp__chrome_devtools__batch runs up to 8 calls sequentially in one round trip. End with includeSnapshot on a supported input action or take_snapshot; avoid duplicate observations. Stop before steps requiring newly observed UIDs or decisions, and place navigation last. Batches stop on errors or document changes, preserve partial results, and never replay actions. Browser tab creation/closure uses browser_open_tab/browser_close_tab; browser_select_tab explicitly binds the new same-site target. -3. Inspect the tools already registered by the site with browser_context. Use browser_webmcp_call when existing tools meet the need; copy the current targets’ frameId, documentId and revision. The upstream list_webmcp_tools/execute_webmcp_tool routes are unavailable because they lack Browser revision identity. Existing site WebMCP and generated WebMCP coexist in one tool inventory; the presence of either does not exclude the other. +3. Inspect the tools already registered by the site with browser_context. Use browser_webmcp_call when existing tools meet the need; pass only the current toolRef and input. The host supplies frame, document and revision identities; catalog digest is never a tool revision. The upstream list_webmcp_tools/execute_webmcp_tool routes are unavailable because they lack Browser revision identity. Existing site WebMCP and generated WebMCP coexist in one tool inventory; the presence of either does not exclude the other. 4. Call browser_set_mode with mode "builder" when authoring or repairing. Read webmcp_read_source before editing; preserve working capabilities and the existing source unless the user requested replacement. If browser_context reports GitHub provenance or an upstream baseline, use webmcp_project with operation "start" to resume/create the dedicated Git working project from the installed revision. This preserves the previous Builder draft. Then webmcp_read_source returns the project's authoritative sourcePath and sourceDigest. Every webmcp_write_source call must supply that sourceDigest as expectedDigest; reread on a stale-write error. Never keep editing the old draft after starting a community project. For requested upstream updates, use webmcp_project "preview" and review its diff and conflicts, then "merge" with its token. Preview does not change the working project; merge creates a checkpoint and never activates code. Resolve conflict files in the reported project directory, preserving local capabilities and upstream fixes, then use "finish". "abort" returns to the pre-merge checkpoint. Do not apply while merging. Manifest, license, README and companion skills belong to the same Git project. Local builds preserve an upstream baseline separately from their changed source digest.
