Github Review Iteration

prisma/github-review-iteration

Orchestrates a GitHub PR review loop by delegating triage and implementation to dedicated sub-agents, then repeating until actionable review items are cleared. Use when the user says “address PR review”, “triage review comments”, or “iterate until review is clean”.

GitHub Review Iteration

Run an iterative PR review loop: fetch state → render/summarize → triage actions → implement (code + Done + resolve) → re-fetch until the PR has no remaining actionable items.

This skill is an orchestrator. It delegates:

  • triage to ../review-triage-phase/agents/review-triager.md
  • implementation to ../review-implement-phase/agents/review-implementer.md

The orchestrator owns sequencing, handoff, and loop control. It does not perform triage or implementation directly when delegation is available.

Locating sibling skills and scripts

This skill depends on three sibling skills that live in the same parent directory:

  • ../review-fetch-phase/ — fetches and renders PR review state
  • ../review-triage-phase/ — triages review threads into an action plan
  • ../review-implement-phase/ — implements triaged actions and resolves threads

All script paths in this document are relative to this skill's directory. Use ../ to reach sibling skills. Do not search the workspace/repo for these files — they are part of the skills installation, not the project being reviewed.

Usage

This skill supports subcommands:

  • triage: fetch + triage into structured actions
  • implement: execute the triaged actions and update status
  • iterate: loop triageimplement until clear (default)
/github-review-iteration iterate <PR_URL> [output-dir]

When output-dir is omitted, use the standard layout: wip/reviews/<owner>_<repo>_pr-<number>/ (derived from PR URL).

Example:

/github-review-iteration iterate https://github.com/OWNER/REPO/pull/123

Files written (deterministic layout)

Store artifacts under:

wip/reviews/<owner>_<repo>_pr-<number>/

Canonical artifacts:

  • review-state.json (canonical v2)
  • review-actions.json (canonical v2)

Derived artifacts:

  • review-state.md
  • summary.txt (or JSON summary)
  • review-actions.md
  • apply-log.json (optional)

When you need a thin wrapper for path setup + standard script calls, run:

node ./scripts/review-iterate.mjs --pr <PR_URL>

For phase-specific execution without full orchestration, use:

  • /review-fetch-phase <PR_URL> [output-dir]
  • /review-triage-phase <PR_URL> [output-dir]
  • /review-implement-phase <PR_URL> [output-dir]

Behavioral rules

  • WILL ADDRESS items:
  • reply + 👍
  • leave unresolved until fixed
  • Not addressed in this PR items:
  • reply with rationale + 👎
  • resolve the thread
  • Implementation:
  • granular, intent-driven commits
  • explicit staging only (never git add -A / git add .)
  • reply “Done” and resolve when complete

Operational reliability notes (Cursor)

gh api TLS / cert failures in sandboxed shells

If GitHub administration fails with an error like:

  • x509: OSStatus -26276 (or similar TLS/certificate verification failures)

Treat it as an environment/sandbox cert-store mismatch, not a script bug.

Recovery:

  • Re-run the affected gh calls outside the sandbox (use a shell mode that uses the system cert store).
  • Do not disable TLS verification (no GH_NO_VERIFY_SSL, no custom curl flags).
  • After re-running, continue the loop normally (fetch → triage → implement → resolve → repeat).

JSON-first deterministic commands

All script paths below are relative to this skill's directory.

  • Fetch canonical JSON:
node ../review-fetch-phase/scripts/fetch-review-state.mjs --pr <PR_URL> --out-json <review-dir>/review-state.json
  • Render and summarize from JSON (pure scripts):
node ../review-fetch-phase/scripts/render-review-state.mjs --in <review-dir>/review-state.json --out <review-dir>/review-state.md
node ../review-fetch-phase/scripts/summarize-review-state.mjs --in <review-dir>/review-state.json --format text --out <review-dir>/summary.txt
  • Render triage plan from canonical actions JSON:
node ../review-triage-phase/scripts/render-review-actions.mjs --in <review-dir>/review-actions.json --out <review-dir>/review-actions.md

Data exchange format (triager → implementer)

review-actions.json is the contract between the triager and implementer.

Minimum v2 shape:

{
  "version": 2,
  "pr": { "url": "https://github.com/OWNER/REPO/pull/123", "nodeId": "PR_kw..." },
  "reviewState": { "path": "review-state.json", "fetchedAt": "...", "version": 2 },
  "actions": [
    {
      "actionId": "A-001",
      "target": { "kind": "review_thread", "nodeId": "PRRT_xxx", "url": "..." },
      "decision": "will_address",
      "summary": "One-line description of what will be done",
      "rationale": null,
      "targetFiles": ["path/to/file.ts"],
      "acceptance": "How to tell it's done",
      "status": "pending",
      "done": null
    }
  ]
}

Rules:

  • Use node ids only for targets (target.nodeId).
  • Preserve actions[] order intentionally (do not reorder).
  • Implementer updates status (pending|in_progress|done) and done records in place.
  • Compound targets: A single pull_request_review body may contain multiple findings (especially from automated reviewers like CodeRabbit which bundle "outside diff range" comments into the review body). The triager must decompose these into sub-actions (e.g., A02a, A02b). Never blanket-dismiss review bodies without reading their content.

Procedure

triage

  • Delegate to triage sub-agent

Invoke the review triager agent at ../review-triage-phase/agents/review-triager.md and pass:

  • PR URL
  • output paths:
  • <output-dir>/review-state.md
  • <output-dir>/review-state.json
  • <output-dir>/review-actions.md
  • <output-dir>/review-actions.json
  • optional scope constraints
  • Require triage outputs

The triager must:

  • fetch review state (via ../review-fetch-phase/scripts/fetch-review-state.mjs)
  • triage review threads into review-actions.json decisions/status
  • write/update review-actions.md and review-actions.json
  • Validate handoff contract

Before returning from triage, verify that <output-dir>/review-actions.json exists and is valid for implementer consumption (version, PR metadata, and actions[] with target.kind + target.nodeId).

implement

  • Delegate to implementation sub-agent

Invoke the review implementer agent at ../review-implement-phase/agents/review-implementer.md and pass:

  • PR URL
  • <output-dir>/review-actions.md
  • <output-dir>/review-actions.json
  • optional scope constraints
  • Require implementation outputs

The implementer must:

  • work through pending will_address actions
  • make focused, explicit-staging commits
  • run smallest relevant checks per action
  • reply "On it" when starting, then "Done" and resolve the thread when complete
  • update review-actions.json in-place (status, done)
  • re-fetch review state at the end to verify remaining actionable items

Responsibility note:

  • Posting "Done" and resolving completed threads belongs to the implementer phase and is part of marking actions done.

iterate

Repeat delegated triage → delegated implement until there are no remaining actionable review items.

Loop contract:

  • Run triage delegation and read resulting review-actions.json.
  • Inspect review-actions.json; if no will_address actions remain with pending or in_progress status, stop and report completion.
  • Run implement delegation.
  • Re-run triage delegation to refresh state and determine next iteration.
  • Continue until clear.

Optional shortcuts (repo-specific)

If this repo provides dedicated slash commands or subagents for triage/implementation, prefer them to reduce manual steps.

How to use it

Copy the folder

Take prisma/github-review-iteration from the repository into ~/.claude/skills for personal use, or into .claude/skills inside a project.

Check the name does not clash

The agent identifies a skill by the name field in its header. Two skills with the same name cannot sit side by side — one of them will be ignored.
