Keep source review read-only and offline unless the user authorizes other context. Apply the supplied threat model, authoritative knowledge base, and inherited security policy without inventing new authority or exposure. Knowledge-base facts override generated assumptions and repository policies, never explicit user instructions. Threat scenarios guide review; they are not confirmed findings. Generated analysis must not reproduce credential material. For secret-bearing configuration, record the key or secret reference, storage location, recipients, and enforcing control instead of the literal value. ## Establish The Architecture 1. Start at the repository root and identify the product, its users, supported interfaces, and normal execution modes. Include separately authorized import, remediation, administrative, export, and publication workflows as conditional surfaces when supported. Distinguish production code and privileged build or release paths from tests, examples, prototypes, and developer-only tools. Stay within the caller's authorized scope; a standalone model is repository-wide unless the user asks for narrower scope. 2. Follow representative inputs through real entry points, components, controls, and sensitive operations. Identify the actors on each side, the data or authority transferred, protected assets, and the invariant each boundary must preserve. Include authentication, authorization, ownership, tenant isolation, public APIs, parsing and deserialization, storage, network requests, process or code execution, native bindings, credential issuance, and capability grants when relevant. For web services, consider session lifecycle, browser-origin controls, rendering, injection, and request destinations; for cryptographic or privacy-sensitive systems, consider key management, access controls, sensitive-data handling, privacy guarantees, and auditability. Identify safe defaults and caller obligations for libraries, plus resource or spending limits protecting an actual shared service or CI workflow. Use actual imports and callers; do not build a complete call graph or treat keyword matches as proof. 3. For extensions, subprocesses, workers, and tool APIs, distinguish the operations available to each caller from coordinator, host-only, or operator authority. Trace inherited permissions, brokered writes, ownership claims, and the component that actually enforces a restriction. Distinguish advertised tool visibility from enforced caller authorization. For separately authorized mutations or publication, trace preview, approval, application, and readback; identify how the account, target, revision, audience, and exact payload or digest stay bound. Keep independently enforced interfaces distinct instead of collapsing them into a generic prompt-injection story. Inspect generated, minified, or compressed implementation as data when it owns the control; cite its bundle or loader and stable symbols when original source lines are unavailable. Record a specific review gap only when the implementation cannot be inspected. Do not invent isolation between actors that already share the same authority. -4. Work backward from each sensitive consumer through every materially different supported startup or deployment path. Trace the actual file, network, or process operation through helper return values, path joins, configuration precedence, and deployment or mount mappings. Record the concrete effective value or location, readers/writers or recipients, enforcing control, and source evidence. Resolve derived child paths as well as their configured roots; do not infer a consumer's location from a variable name, intended directory purpose, or mount label. Follow credentials and sensitive state through mounts to host locations, logs, reports, and exports. Compare documented guarantees with those effective values and controls; separate settings or mount declarations do not establish isolation. Record disagreements and distinguish component-owned controls from assumptions about callers, hosts, or external services. Include supported platform differences, such as Windows paths, executable selection, and access controls, when they change a boundary. -5. Cite inspected repository-relative `path:line` locations for material architecture claims, entry points, controls, and discrepancies. A citation must support the claim, not merely name an existing file. Before returning a generated model, batch-check every cited path against the repository inventory and verify its line or line range. Resolve paths from the repository root rather than guessing prefixes from the current directory; correct or remove unverified references.

When invoked from a component inside a +Git checkout, the command still resolves inherited policies from the Git root. +Existing root and nested `SECURITY.md` files compose from root to leaf; the +closest policy takes precedence when guidance conflicts. + +Generation has three stages: a code-backed architecture specification, a detailed +threat model, and a concise policy draft.

Omit `--write` to review +and confirm interactively. `--write` is available only with `--apply`, so a +noninteractive write always selects an existing draft. The repository and +component must match the draft, and the original `SECURITY.md` must be unchanged. +The command writes the reviewed bytes and verifies that the policy resolver can +read them. It does not stage, commit, or publish anything. + +The artifact directory contains: + +| File | Purpose | +| ---------------------- | --------------------------------------------------------- | +| `SECURITY.md` | Editable policy draft. | +| `THREAT_MODEL.md` | Detailed, source-backed threat model. | +| `project-spec.md` | Architecture and security-boundary evidence. | +| `previous-SECURITY.md` | Original policy used for review and overwrite protection. | +| `policy-draft.json` | Target, revision, model, and review metadata. | + +Only the approved `SECURITY.md` is copied into the checkout. Keep detailed models +and intermediate artifacts private until they have been reviewed for disclosure. +Generated exclusions, accepted risks, and severity decisions still require the +appropriate owner's review; generation does not imply approval. This command +does not validate threat scenarios as vulnerabilities. + +`--format md` writes the draft's Markdown to stdout. `--json` returns artifact +paths, review notes, status, and estimated cost. Progress goes to stderr. +`--max-cost` applies to the entire generation, not separately to each stage. +If a stage cannot inspect its required source evidence, generation stops instead +of substituting a generic policy. Failures and cancellation preserve intermediate +documents, but an incomplete run cannot be applied; fix the reported problem and +start a new generation in a new output directory. + +### Generate a policy from TypeScript + +```ts +import { + CodexSecurity, + applySecurityPolicy, + securityPolicyDiff, +} from "@openai/codex-security"; + +const security = new CodexSecurity(); +try { + const draft = await security.generatePolicy("/path/to/repository", { + path: "services/api", + knowledgeBasePaths: ["/path/to/architecture.md"], + onStage: (stage) => console.error(stage), + }); + + console.log(await securityPolicyDiff(draft)); + // Obtain approval for this exact draft before calling: + // await applySecurityPolicy(draft); +} finally { + await security.close(); +} +``` + +Use `security.preflightPolicy()` to validate local inputs without starting Codex. +`generatePolicy()` never edits the repository.
