Draft output stays outside every enclosing checkout, and policy +link checks also protect those checkouts. Git metadata cannot be a policy target. +Existing root and nested `SECURITY.md` files compose from root to leaf; the +closest policy takes precedence when guidance conflicts. +If a `SECURITY.md` outside the selected component links to its policy, fix that +link first. This includes a broken link that would become active when the policy +is created. The command rejects these links to keep approval limited to the +selected scope. +Policy links must stay inside the repository. When drafting a root policy, the +command also protects separate reporting policies at `.github/SECURITY.md` and +`docs/SECURITY.md`. + +Generation has three stages: a code-backed architecture specification, a detailed +threat model, and a concise policy draft. In an interactive terminal, the command +asks about facts that materially affect the policy, in groups of at most three +questions. It then shows the exact proposed diff and any decisions that need +owner review. Nothing is written into the repository without confirmation. +If both a ChatGPT sign-in and an API key are available, interactive generation +asks which one to use. Set `--auth chatgpt` or `--auth api-key` to choose +explicitly. + +### Review and apply a saved draft + +Use `--headless` or structured output to generate without questions or a write +prompt. Saved review notes retain material questions and decisions from every +stage, even if the final draft omits them.

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. The original `SECURITY.md`, inherited policies, +and inherited policy links 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. + +An update keeps the previous file so an editor with an old file handle cannot +lose a late save. The command tries to move it into the private artifact +directory. If that move fails, including across filesystems, it keeps a +`.SECURITY.md.*.previous` file beside the target. The CLI prints the recovery path +and includes `recoveryPath` in JSON output. Remove it only after other writers +have closed it and any edits are reconciled. + +Avoid editing the target while application is in progress. A +`recovery_required` result means the replacement needs manual reconciliation. +Inspect its `recoveryPath` and `targetPath` before retrying. + +Save edited drafts as UTF-8. If generation used a custom `--plugin-path`, pass +that option again when applying a saved draft; the saved metadata never selects +executable code. Plugin directories and ZIP files are both supported. Once a +write commits, the command finishes verification even if cancellation arrives. +If verification fails, it exits with an error and reports `written_unverified` +in JSON output. Review the written file and any reported `recoveryPath` before +retrying. A later repeated Ctrl-C or SIGTERM can force the command to stop if +verification does not finish. + +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, policy hashes, revision, model, and review notes. | + +After an update, `recovery-SECURITY-*.md` files can also contain retained previous +policies. They are not removed automatically. + +Only the approved `SECURITY.md` is applied to 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. Explicit output options disable +interactive questions and write prompts. Global filters select fields from the +result; token options apply to the selected format, including Markdown. Progress +goes to stderr. With `--full-output`, policy and validation failures return +`ok: false` and an error message. Plain `--json` retains the recovery status and +paths described above when a write needs attention. +`--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. It accepts `auth`, `path`, +`knowledgeBasePaths`, `outputDir`, `maxCostUsd`, and `signal`, plus progress and +cost callbacks. An optional `answerQuestions` callback supplies owner context; +it receives each group of up to three questions and a cancellation signal. +Without one, questions remain unresolved. Use +`loadSecurityPolicyDraft(repository, artifactDirectory, { path })` to load an +edited saved draft before reviewing and applying it. For a saved custom-plugin +draft, pass `{ pluginPath }` to `applySecurityPolicy()`. Applying returns +`{ targetPath, recoveryPath }`; `recoveryPath` is `null` when no existing file +was replaced. A `SecurityPolicyVerificationError` means the file was written +but verification failed; its `targetPath` identifies the file to inspect.
