Constraint:

• Apply @rules/php/core-standards.mdc
• Apply @rules/git/general.mdc
• Apply @rules/jira/general.mdc
• Apply @rules/reports/general.mdc. CR reply comments and resolved-items updates posted on the GitHub PR stay in canonical English per the rule's Exception — technical CR findings on the GitHub PR (they extend the technical CR thread). The mirrored non-technical summary delegated to @skills/pr-summary/SKILL.md on the linked issue / JIRA ticket follows the language of the source assignment. Never mix languages inside the same comment; never use bilingual Kritické (Critical) style parentheses.
• If the current project uses Laravel, also apply @rules/laravel/laravel.mdc, @rules/laravel/architecture.mdc, @rules/laravel/filament.mdc, and @rules/laravel/livewire.mdc
• Never mix two natural languages inside a single CR comment. The English exception applies to entire comments — not to inline parenthetical glosses.
• Never push direct changes to the main branch
• If the pull request has merge conflicts with the base branch, stop and report it
• Do not introduce new logic unrelated to review feedback

---

Steps

• Identify the task from the provided issue code or URL
• Find all open pull requests for the task
  • If multiple PRs exist, process each independently
• Before processing a PR, switch to the PR branch and pull latest changes following @rules/git/general.mdc Pull Policy, in order: resolve the default branch (DEFAULT_BRANCH="$(git symbolic-ref --short refs/remotes/origin/HEAD | sed 's@^origin/@@')" — never hardcode origin/main), git fetch origin, git pull --rebase to take the PR branch's own remote first, then git rebase "origin/$DEFAULT_BRANCH" to bring the default branch in, resolve any conflicts, and git push --force-with-lease. Do not git pull again after the rebase — it would undo the sync. If the rebase changed composer.lock, run composer install immediately so dependencies match the new lockfile. If the rebase surfaces conflicts that cannot be resolved cleanly, stop and report it (the existing merge-conflict constraint).

For each PR:

• Load PR context by running skills/code-review-github/scripts/load-issue.sh <NUMBER|URL> — the single deterministic entry point. Never call gh issue view, gh pr view, or gh api /repos/.../issues/... directly. Read review comments, files, commits, status checks, and closingIssues off the resulting JSON document. If the script is unavailable (missing tool, exit code 2/3) fall back to the GitHub MCP server, and always prefer the MCP fallback for review-thread / line-anchored comments that the script does not return.
• Load unresolved reviewer threads (mandatory, GitHub). load-issue.sh returns general comments[] and reviews[] but never the line-anchored review threads nor their resolved/unresolved state. Fetch them deterministically with the GraphQL reviewThreads connection — this is not one of the forbidden REST endpoints (gh issue view, gh pr view, gh api /repos/.../issues/...):

  gh api graphql -f query='
  query($owner:String!,$repo:String!,$number:Int!,$cursor:String){
    repository(owner:$owner,name:$repo){
      pullRequest(number:$number){
        reviewThreads(first:100, after:$cursor){
          pageInfo{ hasNextPage endCursor }
          nodes{
            id isResolved path line
            comments(first:100){ nodes{ author{login} body url createdAt } }
          }
        }
      }
    }
  }' -F owner=<owner> -F repo=<repo> -F number=<number>
  

  Do not accept a truncated list — the "every unresolved thread" guarantee depends on completeness. When reviewThreads.pageInfo.hasNextPage is true, repeat the query with -F cursor=<endCursor> until it is false; when any thread's comments.nodes reaches the page size, page that thread's comments the same way. If gh api graphql is unavailable, fall back to the GitHub MCP server for the same thread list plus its resolved state.
• Build the checklist from both sources:
  1. Structured CR findings published by the review skills (general comments come from comments[]).
  2. Unresolved reviewer threads from the reviewThreads query — add every thread where isResolved == false (human reviewer and bot) as a checklist item, and skip every thread where isResolved == true. Record each thread's id so it can be marked resolved once its fix lands (see Resolve addressed reviewer threads below).
• Map each finding to a concrete code or test change

Reproducer extraction (per finding)

For every Critical and Moderate finding, extract the reproducer fields published by the CR skills (@skills/code-review/SKILL.md, @skills/code-review-github/SKILL.md, @skills/code-review-jira/SKILL.md, @skills/security-review/SKILL.md):

• Faulty Example — the minimal snippet or input that reproduces the bug
• Expected Behavior — the assertion target the test must verify
• Test Hint — the layer (unit, integration, feature) and entry point
• Suggested Fix — the minimal corrected snippet that resolves the finding (may be n/a — <reason> when the Fix narrative is sufficient)

Read the reproducer fields off comments[] and body / descriptionText returned by the deterministic loader for the originating tracker instead of re-fetching the issue:

• GitHub-originated reviews: skills/code-review-github/scripts/load-issue.sh <NUMBER|URL>. Never call gh issue view, gh pr view, or gh api /repos/.../issues/... directly.
• JIRA-originated reviews: skills/code-review-jira/scripts/load-issue.sh <KEY|URL>. Never call acli directly.

Use these to write a failing test before applying the fix:

1. Drop the Faulty Example into a new test case at the layer named in the Test Hint.
2. Assert the Expected Behavior — the test must fail on the current code.
3. Apply the Suggested Fix snippet (or the Fix narrative when Suggested Fix is n/a); rerun the test until it passes.

If a CR-skill finding lacks Faulty Example, Expected Behavior, or Test Hint, request a CR rerun rather than guessing — the CR skills are responsible for providing them. Suggested Fix may legitimately be n/a per the CR rules.

Free-form reviewer threads are exempt from the reproducer requirement. Unresolved threads written by human reviewers will not carry the four structured fields. Do not request a CR rerun for them and do not block. Instead, derive the intent from the comment text, apply the minimal best-effort fix that satisfies it, and add or adjust a test at your discretion (a regression test when the comment describes a behavior bug; none when it is a naming / readability / dead-code remark). Keep the change scoped strictly to what the reviewer asked for. The exemption removes only the mandatory reproducer workflow — a behavior-changing best-effort fix still has to satisfy the diff-scoped coverage gate enforced by the Review loop below (@rules/php/core-standards.mdc Testing).

---

Pre-fix phase — pre-existing issue handling

While reading the affected files in preparation for the CR fixes, you may encounter problems that are unrelated to the reviewer feedback but were already present in those files. The following categories qualify:

• Bugs — incorrect logic, broken edge cases, null-dereference risks, race conditions, or runtime errors that exist before this CR.
• Project-rule violations — code that contradicts any rule listed in this skill's Constraints block (@rules/php/core-standards.mdc, @rules/git/general.mdc, @rules/laravel/*, …) or any other rule under .claude/rules/.
• Security vulnerabilities — anything @rules/security/backend.md, @rules/security/frontend.md, or @rules/security/mobile.md would flag (injection, missing authn/authz, unsafe deserialization, sensitive-data exposure, …).

Rules:

1. Do not silently ignore a pre-existing issue you encountered in a file you had to read for the CR fixes — fix it in this PR.
2. Do not expand scope by actively scanning unrelated files for additional pre-existing issues. Limit attention to files already touched by the CR fixes.
3. Land each pre-existing fix in its own separate commit, ordered before the CR-fix commits:
   • Use a Conventional Commits subject per @rules/git/general.mdc: fix(<scope>): pre-existing — <description> for bugs and security, refactor(<scope>): pre-existing — <description> for rule violations without behavior change.
   • The pre-existing — prefix is mandatory so reviewers can identify these commits at a glance.
   • Test coverage workflow depends on the commit type:
     • fix(<scope>): pre-existing — … (bug, security) — add the regression test in the same commit as the fix; the test must fail before the fix lands and pass after.
     • refactor(<scope>): pre-existing — … (project-rule violation, behavior-preserving) — apply @rules/refactoring/general.mdc Test Coverage Contract: when the target lines are below 100% coverage, author a dedicated test(<scope>): cover <area> before pre-existing refactor commit before the refactor commit, and do not modify pre-existing tests inside the refactor commit (mechanical renames forced by the refactor itself stay exempt and must be flagged in the commit body).
   • Either way, pre-existing fixes follow the same diff-scoped 100% coverage rule as CR fixes.
4. In the cr-status PR comment posted during PR update, list every pre-existing fix under a ## Pre-existing fixes heading with a one-line rationale, so reviewers can review them independently of the CR thread.
5. If a pre-existing issue is non-trivial (would significantly expand the PR or requires architectural discussion), do not fix it. Surface it in the cr-status comment as a deferred follow-up with the reason — the reviewer can then file a follow-up issue.

---

Apply fixes

• Apply only requested review changes
• Keep scope strictly limited to review feedback
• Ensure DRY violations are included and resolved
• All production code changes must follow:
  • @skills/class-refactoring/SKILL.md

---

Testing

• If tests are required or missing:
  • Run @skills/create-missing-tests-in-pr/SKILL.md
• Ensure current changes have 100% coverage for the changed files only, using the project's available coverage tooling (per the Coverage gate in @skills/code-review/SKILL.md). Do not gate on the full-suite coverage percentage during a CR / review loop iteration.
• Run only relevant tests for changed files
• If migrations were added, run php artisan migrate

---

Review loop (mandatory — convergence gate)

This is a blocking loop. Do not advance to Finalization, PR update, or Completion until the loop converges. The final report (technical and non-technical) is published only once, after convergence.

1. Initialise iteration = 1 and maxIterations = 5 (safety net to avoid runaway loops).
2. Run the review inline. Invoke the appropriate CR wrapper directly in this skill's context — do not dispatch as a subagent. Each iteration re-invokes the CR wrapper inline so it reloads the diff after the latest fix commit:
   • GitHub: @skills/code-review-github/SKILL.md
   • JIRA: @skills/code-review-jira/SKILL.md The invocation must include the explicit quiet-mode instruction (see Quiet review runs below). The review run must not publish to the PR or to the issue tracker during loop iterations — capture findings in memory only.
3. Count criticalCount and moderateCount in the latest review.
4. If criticalCount + moderateCount == 0 → converged, exit the loop.
5. Otherwise, apply the Suggested Fix snippet from each Critical / Moderate finding using the Reproducer extraction workflow above, run pre-push quality gates on touched files, increment iteration, and go back to step 2.
6. If iteration > maxIterations and the loop still has not converged, stop and surface the remaining findings to the user — do not push or publish a partial report. The user must triage the residual findings manually before any final report goes out.

Quiet review runs (during the loop)

• During iterations 1…N–1 of the loop, invoke the review skill with the explicit instruction "do not publish; return findings as in-memory markdown for this loop iteration only". Both code-review-github and code-review-jira honour the suppression: no PR comment, no JIRA comment, no linked-issue summary is posted while the loop is still iterating.
• The very last iteration (the one that observes criticalCount + moderateCount == 0) is the only iteration whose output is published — that publication is performed by the PR update + Completion steps below, not by the review skill itself.
• Loop iterations may write quality-gate output (composer scripts, build logs) to the local terminal — that is not "publishing" and is allowed.

---

Pre-push quality gates

• Discover available fixers and checkers (prefer Phing targets from build.xml/phing.xml; fall back to Composer scripts in composer.json)
• Run available fixers on all changed files and fix any violations
• Run available checkers/analyzers on all changed files and resolve all reported errors

Finalization (only after Review loop converged)

Precondition: the Review loop above must have exited with criticalCount + moderateCount == 0. If the loop hit maxIterations without converging, do not proceed — return the remaining findings to the user for manual triage instead.

• Do not auto-invoke @skills/test-like-human/SKILL.md. The user-perspective testing skill runs on demand only — leave it for the user to trigger via /test-like-human after the PR is updated.
• Commit and push changes
• If PR does not exist, create it according to @rules/git/general.mdc
  • Title in English (per @rules/git/general.mdc)
  • Body in the assignment language (per @rules/reports/general.mdc)

---

PR update (only after Review loop converged)

Precondition: same as Finalization — convergence required.

• Publish the resolved-items report through the publish helper using the dedicated cr-status marker namespace, so the status comment is identifiable as a status post (separate from the CR comment in the cr-comment namespace). Concretely:
  • GitHub PR: skills/code-review-github/scripts/upsert-comment.sh <PR-NUMBER|URL> - cr-status (body on stdin). The helper appends <!-- cr-status:actor=<gh-login> --> to the body for traceability and POSTs a new comment on every run — it never PATCHes a prior status comment. Action (created) is logged on stderr; include it in the in-conversation completion report.
  • JIRA-originated reviews that also mirror to a JIRA ticket: skills/code-review-jira/scripts/upsert-comment.sh <KEY|URL> - cr-status. The helper appends {anchor:cr-status-actor-<slug>} and edits / adds the comment via acli (JIRA MCP fallback on exit code 4) — JIRA-side upsert behavior is unchanged.
• Do not quote / reply to a previous CR or status comment — the always-new-comment convention (GitHub) replaces the previous quoting / in-place edit flow entirely, and every converge run adds its own self-contained status comment so the chronological sequence is the audit trail. The CR comment (cr-comment namespace) stays untouched by this skill.
• Mark resolved items (checkbox or inline) inside the freshly posted body in all cases.
• When Pre-fix phase produced at least one pre-existing fix commit, render a dedicated ## Pre-existing fixes section in the cr-status body listing each commit subject (fix/refactor(<scope>): pre-existing — …) with a one-line rationale derived from the commit body, so reviewers can review the pre-existing fixes independently of the CR thread. Omit the section entirely when no pre-existing fix landed (consistent with the always-omit-empty-section convention).

Resolve addressed reviewer threads (GitHub)

After the fixes are committed and pushed (Finalization above), mark every reviewer review thread whose finding was actually fixed as resolved, using the thread id captured during intake:

gh api graphql -f query='mutation($threadId:ID!){ resolveReviewThread(input:{threadId:$threadId}){ thread{ isResolved } } }' -F threadId=<thread-id>

• Resolve only threads that were fixed. Leave a thread unresolved when its point was rejected or deferred, and record the rejection reason in the cr-status report instead of resolving it.
• If gh api graphql is unavailable, fall back to the GitHub MCP server's resolve-review-thread operation.
• Resolving a thread is a GitHub PR state change, not a code change — it stays within the read-fixes-push-resolve flow this skill already owns and never touches the protected main branch.

Per-item justification (required)

Every resolved review point in the PR comment must include a brief justification using this format:

- [x] {short finding title}
  - **Why:** {what was wrong / what the reviewer asked for}
  - **Reason:** {root cause or rule that was violated}
  - **Solution:** {what was changed and why this is the best fit}

Rules:

• Keep each line one sentence max.
• Skip the section only if a point was rejected or deferred — in that case state the rejection reason instead.
• Do not pad with filler, restate the obvious, or paraphrase the diff.

---

Completion (final, single publish)

Precondition: Review loop has converged (criticalCount + moderateCount == 0).

• Run the final publishing run inline. Invoke the appropriate CR wrapper directly in this skill's context with publishing enabled — this is the only review whose output reaches the PR / issue tracker. The invocation must include the PR URL, the converged state (Critical + Moderate == 0), and the instruction to post the final PR comment + linked-issue / JIRA mirror per the CR wrapper's contract. Do not dispatch as a subagent — run it sequentially in the current context:
  • GitHub: @skills/code-review-github/SKILL.md
  • JIRA: @skills/code-review-jira/SKILL.md
• Share a concise completion report (in-conversation, not on the tracker):
  • PR link
  • resolved items
  • reviewer threads resolved (count) and any left unresolved with the rejection / deferral reason
  • loop iteration count and final convergence status
  • remaining blockers (if any — should be empty when convergence was reached)

---

Principles

• Resolve review feedback, do not expand scope
• Prefer minimal changes over unnecessary refactoring
• Do not introduce new bugs while fixing existing ones
• Keep changes traceable to review comments
• Ensure every review comment is explicitly addressed
• Treat unresolved GitHub reviewer threads as first-class checklist items; skip already-resolved threads, and resolve a thread only after its fix lands
• Avoid unnecessary commits or noise

Output Humanization

• Use blader/humanizer for all skill outputs to keep the text natural and human-friendly.
