The CI page leads with uses: evloghq/action@v1 (two lines, no committed map, no token) and keeps the npx evlog map --format github recipe under "Without the action" for workflows that take no third-party actions. "Pin the version" notes the action pins the CLI for you; the monorepo section shows the action's packages: input first, then the CLI matrix with per-app thresholds.

The review-logging-patterns skill points at the action in its CI section, and the CLI README's --format github row links to it.

Docs, a skill and a README: no changeset. pnpm content:lint 100 on all three.

📝 Walkthrough

Walkthrough

CI guidance now documents the evlog GitHub Action, CLI GitHub output, and monorepo workflows with package inputs or per-app thresholds.

Changes

CI guidance

Layer / File(s) Summary
GitHub Action workflow guidance
apps/docs/content/3.cli/5.ci.md, packages/cli/README.md, skills/review-logging-patterns/SKILL.md
Documents the action workflow, including its base comparison, annotations, summary, comment, permissions, and CLI version. Related guidance describes the action’s base scan and its CLI README features.
CLI output and monorepo workflows
apps/docs/content/3.cli/5.ci.md
Describes CLI GitHub output and updates monorepo examples to use package directory/glob inputs or app-specific thresholds.

Priority: ⬇️ Low

Estimated code review effort: 2 (Simple) | ~10 minutes

Change: Other

Merge Risk: 🔵 Low · up to 5a31d

Users who adopt this guidance could run changed action code with pull-request write access on eligible same-repository pull requests. Pin both references before relying on the example; the concern is bounded to workflows using the guidance.

Security Architecture Review

Security architecture risk: 🔵 Low · up to 5a31d

The recommended workflow lets an external action update pull-request state while referencing a movable version tag. Exposure depends on users adopting the example and on the permissions available to each run; normal fork restrictions limit it. This PR changes guidance, not a deployed workflow.

Retained concerns

  • Low · security · observed: The new recommended workflow explicitly grants an external action pull-request write authority. That authority enables repository-state mutation even though annotations and the summary are documented to work without it. Normal fork restrictions narrow exposure but do not remove this trust boundary in eligible runs.
  • Low · security · observed: The newly recommended evloghq/action@v1 reference can resolve to different action code after a tag move, including in runs with pull-request write authority. The statement that the action pins its CLI does not establish immutable action code or an explicit reviewed upgrade boundary.
Security review details

Security Blast Radius

  • inferred — The supported token scope is pull-request mutation in each adopting repository where write permission is effective. A compromised action can also execute in that job's runner environment. This does not establish organization-wide authority, production access, or compromise of independent services. Each adopter independently exposes its workflow; aggregate adoption is unknown.

Security Findings and Attack Paths

  • inferred — The retained findings concern explicit write authority and mutable external code selection. An attacker able to control the referenced action tag or its publisher could substitute code that executes in an adopting workflow and accesses its job token. In an eligible write-capable run, that code could mutate pull-request state. Merely submitting an ordinary fork pull request does not establish this attack path.

Trust Boundaries and Controls

  • observed — GitHub's normal fork permission downgrade is the strongest counterevidence to unrestricted external reachability; repository settings can affect write-token eligibility. Actions can access github.token without an explicit token input, so the documentation's statement that no token must be created is not a credential-isolation guarantee.

Hardening Proposals

  • proposed — Use a reviewed full commit SHA for the external action and distinguish CLI-version pinning from action-code immutability. Offer read-only reporting as the default, with pull-request write permission explicitly enabled when comment updates are desired.

GitHub Actions documentation immutable full commit SHA action pinning mutable tags github.token context action GITHUB_TOKEN permissions pull-requests write

💡 Result:

Inspection citation: inspection_85d7b258932770d0c691a81a9e6d35de

GitHub’s documentation supports these points:

- **Pin actions to full commit SHAs for immutability.** GitHub says a full-length commit SHA is currently the only way to reference an action immutably; tags and branches can move. Verify the SHA belongs to the action’s repository. ([docs.github.com](https://docs.github.com/en/actions/reference/security/secure-use?learn=getting_started&learnProduct=actions&utm_source=openai))
- **`github.token` is available to actions.** An action can access the workflow’s `GITHUB_TOKEN` through the `github.token` context even if you don’t explicitly pass it. ([docs.github.com](https://docs.github.com/en/actions/tutorials/authenticate-with-github_token?force_isolation=true&utm_source=openai))
- **Grant only the needed permission.** To allow pull-request writes, set `permissions: pull-requests: write`. When you specify permissions, unspecified scopes become `none`; forked `pull_request` workflows may have write permissions downgraded to read-only, depending on repository settings. ([docs.github.com](https://docs.github.com/en/actions/reference/workflows-and-actions/workflow-syntax?utm_source=openai))

```yaml
permissions:
  pull-requests: write

steps:
  - uses: owner/action@<full-40-character-commit-SHA>
```

The cited docs establish token availability and permission configuration; whether an action actually uses `github.token` to write pull requests depends on that action’s implementation.

Security Misconfiguration

Reachability: External
Exploitability: Difficult
CWE: CWE-494 — Download of Code Without Integrity Check

Pin both action references to a full commit SHA. The v1 tag can move, and the documented workflow grants pull-requests: write. Action code can access github.token without an explicit input. Fork-triggered pull_request runs normally receive a read-only token, but that safeguard does not cover same-repository pull requests.

Use the full commit SHA for the intended release in both references:

Pin the action references
-      - uses: evloghq/action@v1
+      - uses: evloghq/action@<full-commit-SHA>
-On GitHub Actions, suggest the [evlog action](https://github.com/evloghq/action) (`uses: evloghq/action@v1` with `min-score`): it scans the pull request base itself, so no map file has to be committed, and puts regressions on the diff and in one comment. The commands below are the same gate from a `run:` step.
