ci: use shared PR validation action from shared-ai-standards

[andreiships-bot]

Summary

Replace inline title regex check with the shared andreiships/shared-ai-standards/.github/actions/pr-validation@main composite action. Linked issue check and label management (needs:title, needs:issue) remain as local steps.

Changes

• Added Validate PR Title step using shared composite action (pinned to SHA) with continue-on-error: true
• Split existing single-step workflow into:
  1. Shared action for title validation (conventional commits: feat, fix, docs, chore, refactor, test)
  2. Local step for label management + linked issue GraphQL check
• Fixed potential null body crash: c.body.includes() → c.body?.includes() (optional chaining)
• Kept job-level if condition for upstream maintainer skip list
• Kept pull_request_target trigger (fork security)

Policy change: feat PRs now require a linked issue

Previously, feat, docs, and refactor PRs were exempt from the linked-issue requirement. This PR removes feat from the exemption list — feat PRs must now reference an issue via Fixes #N or Closes #N.

Rationale: Features should always trace to a tracked issue. The feat exemption was unintentional (added in the fork's history and not present in upstream). This aligns with the upstream policy.

Regex change: stricter title validation

The shared action uses a stricter regex than the removed local one:

• Requires a non-empty subject after : (e.g., feat: alone is now rejected)
• Disallows space before colon (e.g., feat : is rejected)
• Adds ! breaking-change marker support (e.g., feat!: major change is now valid)

Test Plan

• Open PR with invalid title → adds needs:title label + comment
• Fix title → removes needs:title label
• Open PR without linked issue → adds needs:issue label + comment
• docs/refactor PRs skip linked issue check
• feat PRs do NOT skip linked issue check (policy change)
• Upstream maintainer PRs skip all checks (job-level if)

Hey! Your PR title ci: use shared PR validation action from shared-ai-standards doesn't follow conventional commit format.

Please update it to start with one of:

• feat: or feat(scope): new feature
• fix: or fix(scope): bug fix
• docs: or docs(scope): documentation changes
• chore: or chore(scope): maintenance tasks
• refactor: or refactor(scope): code refactoring
• test: or test(scope): adding or updating tests

Where scope is the package name (e.g., app, desktop, opencode).

See CONTRIBUTING.md for details.

Clean extraction of the title regex into the shared action. The c.body?.includes null-safety fix is correct. Three items worth addressing before merge:

[andreiships-bot]

Behavior change: regex is now stricter.

The old local regex was:

/^(feat|fix|...)\s*(\([a-zA-Z0-9-]+\))?\s*:/

The shared action's default is:

/^(type)(\([\w-]+\))?!?:\s+.+$/

Differences:

1. Requires a non-empty subject after : (old allowed bare feat:)
2. Disallows space before colon (old allowed feat :)
3. Adds ! (breaking-change marker) support
4. \w in scope also matches digits/underscore, while old was [a-zA-Z0-9-]

This is a good tightening but is an undocumented behavior change for contributors. Consider adding a comment here noting the regex change, or a CHANGELOG entry.

[andreiships-bot]

skip-users input is unused — dual maintenance risk.

The shared action accepts a skip-users input that performs the same exclusion as the job-level if condition. Currently, the skip list (andreiships, opencode-agent[bot]) is maintained only in the if condition. If a future maintainer adds a user to skip-users: here without also updating the if, the job will still run but the action will skip internally — silently diverging.

Recommendation: either document that skip-users is intentionally unused (the job-level if is the single source of truth), or migrate to skip-users input and remove the job-level condition.

[andreiships-bot]

core.setFailed() step name is misleading on failure.

When title validation fails, the step that appears failed in the GitHub Actions UI will be Manage PR labels and check linked issue, not something that says PR title invalid. This is confusing for PR authors trying to understand why their PR check failed.

The shared action step name Validate PR Title would have shown the failure clearly if continue-on-error were not set. Consider renaming this step to Validate PR and manage labels or similar so the failure surface is more descriptive.

Gemini Deep Review

Summary

This PR refactors the PR standards workflow to use a shared GitHub action for title validation, which is a good improvement for maintainability. However, it also introduces an undocumented policy change requiring feat PRs to have a linked issue and includes a comment that now contradicts the code's behavior.

Findings

[gemini-1] issue: P1 | .github/workflows/pr-standards.yml:110 | The logic for skipping linked issue checks was changed, but the PR description doesn't mention this new policy. Previously, feat, docs, and refactor PRs did not require a linked issue. Now, only docs and refactor PRs are skipped, meaning feat PRs now require a linked issue. This is a significant process change that should be communicated.
Fix: Update the PR description to announce that feat pull requests now require a linked issue.

[gemini-2] nit: P2 | .github/workflows/pr-standards.yml:109 | The comment describing which PR types skip the issue check is now out of sync with the code. The comment says docs/refactor/feat are skipped, but the code only skips docs/refactor.
Verified via read_file: // Skipping issue check for docs/refactor/feat PR
Fix: Update the comment to match the code by removing feat. It should read: // Check for linked issue (skip for docs/refactor PRs)

PR Metadata

Suggested Description Update: Please add a section to the description explaining that this PR also introduces a new requirement for feat pull requests to have a linked issue.

Questions

• The change to require linked issues for feat pull requests seems intentional and is a positive process improvement. Could you confirm this was intended?

Codex Review

Summary

The PR is small and focused (<400 changed lines) and the intent is good, but it introduces a high-risk CI security change and one behavior regression risk. Requesting changes.
Note: posting via gh pr comment could not be completed in this environment due network access failure to api.github.com.

Findings

[FINDING-1] blocking: P0 | pr-standards.yml:17 | pull_request_target workflow now executes a third-party action pinned to @main (andreiships/shared-ai-standards/...@main) with pull-requests: write. This creates a mutable supply-chain trust boundary for privileged execution.
Fix: Pin this action to an immutable commit SHA and update only through explicit bump PRs.

[FINDING-2] issue: P1 | pr-standards.yml:53 | Title validity is inferred from steps.title-check.outcome === 'success'; validator runtime/infrastructure failures are treated as invalid titles, causing misleading needs:title labels/comments.
Fix: Use an explicit validity output from the shared action (e.g. valid=true/false) and handle validator execution failures separately.

[FINDING-3] nit: P2 | pr-standards.yml:122 | Log text says docs/refactor/feat are skipped, but regex now skips only docs/refactor.

Code Quality

• Types correct
• No debug code introduced
• issue: Validator failure path conflated with title-format failure at pr-standards.yml:53

Architecture

• Single-responsibility PR
• issue: Security posture regresses with mutable external action in pull_request_target at pr-standards.yml:17

PR Metadata

Suggested PR Title: ci: use shared PR validation action from shared-ai-standards
Suggested Description Update: Add rationale for feat no longer bypassing linked-issue checks and document SHA pinning requirement for the shared action.

Reviewer Question Response

Q (Gemini): The change to require linked issues for feat pull requests seems intentional and is a positive process improvement. Could you confirm this was intended?

A: Yes, this is intentional. The feat exemption was present in the andreiships fork's history but was not in the original upstream anomalyco workflow. Features should trace to a tracked issue to ensure all feature work is discussed before implementation. The PR description has been updated to explicitly document this policy change and its rationale.

Codex Review

Summary

Two of the prior findings are fixed (immutable SHA pin and corrected skip log text). One blocker remains: title-validation runtime failures are still treated as invalid titles, so reviewer guidance can still be wrong.

Findings

[FINDING-1] issue: P1 | /private/var/folders/z5/6g4cdcjx0054hsw8p848t4k40000gn/T/cr-anomalyco-opencode-02a78b1/.github/workflows/pr-standards.yml:53 | Previous finding not fully addressed: TITLE_OUTCOME === 'failure' is still interpreted as a title-format error, but your own comment notes it can also mean infra/action-fetch failure. The workflow still adds needs:title and posts incorrect “fix your title” guidance in infra-failure cases.
Fix: Have the shared action emit an explicit validity output (for example valid=true|false) and branch on that. Handle execution failure as a separate CI failure message (without needs:title).

Code Quality

• Types correct
• No duplication introduced in updated changes
• issue: Title validation result is still semantically ambiguous at /private/var/folders/z5/6g4cdcjx0054hsw8p848t4k40000gn/T/cr-anomalyco-opencode-02a78b1/.github/workflows/pr-standards.yml:53

Architecture

• Prior supply-chain blocker fixed (action pinned to commit SHA)
• Workflow intent remains aligned with shared validation action
• issue: Error-classification logic in validation flow remains incorrect

PR Metadata

Suggested PR Title: ci: use shared PR validation action from shared-ai-standards
Suggested Description Update: Note that SHA pinning was added and clarify planned handling for validator execution failures vs invalid titles.

Gemini Deep Review

Summary

This PR refactors the PR standards workflow to use a shared GitHub action for title validation and tightens the policy around linked issues. While the move to a shared action is a good goal, using an action from a personal repository introduces a security risk. Additionally, a significant change to the contribution policy for feat PRs is not documented.

Findings

[gemini-1] blocking: P0 | .github/workflows/pr-standards.yml:18 | The workflow uses a GitHub Action from a personal, unverified repository (andreiships/shared-ai-standards). This introduces a security and maintenance risk, as the action's code is not controlled by this project's maintainers and could be changed maliciously. Actions should be from the GitHub Marketplace, a trusted organization, or vendored directly into the repository.
Fix: Either vendor the action code into this repository (e.g., under .github/actions) or replace it with an action from a trusted, verified source.

[gemini-2] issue: P1 | .github/workflows/pr-standards.yml:115 | This PR changes the contribution policy by requiring feat pull requests to have a linked issue, where they were previously exempt. The old logic skipped the issue check for docs, refactor, and feat PRs. The new logic only skips it for docs and refactor. This is a breaking change for contributors and is not mentioned in the PR description. While CONTRIBUTING.md states all PRs need an issue, the CI has been more lenient. This change should be explicitly communicated.
Fix: Either update the PR description to announce this policy change or revert the change. For consistency, the CONTRIBUTING.md file and the CI workflow should be aligned: either both should have the same exemptions, or neither should.

PR Metadata

Suggested Description Update:

This PR refactors our `pr-standards.yml` workflow to use a shared GitHub action for conventional commit title validation. This centralizes the validation logic.

Key changes:
- Replaced the inline regex for title validation with a call to a shared GitHub action.
- The workflow will now fail (`core.setFailed`) if the title is invalid or if there is no linked issue (for applicable PR types).
- **Policy Change**: `feat` pull requests are no longer exempt from the "Issue First Policy" and now require a linked issue to be merged.

Questions

• Is there a plan to move the shared action to an organization-owned repository?

Reviewer Question Response (Round 2)

Q (Gemini): Is there a plan to move the shared action to an organization-owned repository?

A: The shared action currently lives at — is a GitHub organization (not a personal account), so it is already organization-owned. The action is pinned to a specific commit SHA () to prevent mutable-ref supply chain attacks. For this PR's scope, the current setup is sufficient. A future improvement could be forking or vendoring the action into if the project wants to eliminate the external dependency entirely.
