Review code quality, receive feedback with technical rigor, verify completion claims. Use before PRs, after implementing features, when claiming task completion. Includes scout-based edge case detection and native Task pipeline orchestration.
We split this skill into the rules it gives an agent
11 rules. 0 are common, 10 are distinctive, and 1 is very specific to this project.
0
Common
Most of the 184 edited versions we read keep these.
10
Distinctive
This author's own choices. Worth a look.
1
Very specific
Tied to their project's names, files or tools. Probably skip.

Iron Law: NO COMPLETION CLAIMS WITHOUT FRESH VERIFICATION EVIDENCE

Verify. Scout. Question. Then implement.
“Common” is measured: kept by at least 6 in 10 of the 184 edited versions of this file we could read. “Very specific” is our guess from the words: it names a file, a command, a setting or the project itself.

Code Review
Guide proper code review practices emphasizing technical rigor, evidence-based claims, and verification over performative responses.
Default (No Arguments)
If invoked with context (recent changes/PR), proceed with review. If invoked WITHOUT arguments, use AskUserQuestion to present available review operations:
| Operation | Description |
(default) | Review recent changes/PR |
codebase | Full codebase scan & analysis |
codebase parallel | Parallel multi-reviewer audit |
Present as options via AskUserQuestion with header "Review Operation", question "What would you like to do?".
Core Principle
YAGNI, KISS, DRY always. Technical correctness over social comfort. Be honest, be brutal, straight to the point, and be concise.
Verify before implementing. Ask before assuming. Evidence before claims.
Practices
| Practice | When | Reference |
| Receiving feedback | Unclear feedback, external reviewers, needs prioritization | references/code-review-reception.md |
| Requesting review | After tasks, before merge, stuck on problem | references/requesting-code-review.md |
| Verification gates | Before any completion claim, commit, PR | references/verification-before-completion.md |
| Edge case scouting | After implementation, before review | references/edge-case-scouting.md |
| Task-managed reviews | Multi-file features (3+ files), parallel reviewers, fix cycles | references/task-management-reviews.md |
Quick Decision Tree
SITUATION?
│
├─ Received feedback → STOP if unclear, verify if external, implement if human partner
├─ Completed work → Scout edge cases → Request code-reviewer subagent
├─ Multi-file feature (3+ files) → Create review pipeline tasks (scout→review→fix→verify)
└─ About to claim status → RUN verification command FIRSTReceiving Feedback
Pattern: READ → UNDERSTAND → VERIFY → EVALUATE → RESPOND → IMPLEMENT
Rules:
- No performative agreement: "You're absolutely right!", "Great point!"
- No implementation before verification
- Restate, ask questions, push back with reasoning, or just work
- YAGNI check: grep for usage before implementing "proper" features
Source handling:
- Human partner: Trusted - implement after understanding
- External reviewers: Verify technically, check breakage, push back if wrong
Full protocol: references/code-review-reception.md
Requesting Review
When: After each task, major features, before merge
Process:
- Scout edge cases first (see below)
- Get SHAs:
BASE_SHA=$(git rev-parse HEAD~1)andHEAD_SHA=$(git rev-parse HEAD) - Dispatch code-reviewer subagent with: WHAT, PLAN, BASE_SHA, HEAD_SHA, DESCRIPTION
- Fix Critical immediately, Important before proceeding
Full protocol: references/requesting-code-review.md
Edge Case Scouting
When: After implementation, before requesting code-reviewer
Process:
- Invoke
/scoutwith edge-case-focused prompt - Scout analyzes: affected files, data flows, error paths, boundary conditions
- Review scout findings for potential issues
- Address critical gaps before code review
Full protocol: references/edge-case-scouting.md
Task-Managed Review Pipeline
When: Multi-file features (3+ changed files), parallel code-reviewer scopes, review cycles with Critical fix iterations.
Pipeline: scout → review → fix → verify (each a Task with dependency chain)
TaskCreate: "Scout edge cases" → pending
TaskCreate: "Review implementation" → pending, blockedBy: [scout]
TaskCreate: "Fix critical issues" → pending, blockedBy: [review]
TaskCreate: "Verify fixes pass" → pending, blockedBy: [fix]Parallel reviews: Spawn scoped code-reviewer subagents for independent file groups (e.g., backend + frontend). Fix task blocks on all reviewers completing.
Re-review cycles: If fixes introduce new issues, create cycle-2 review task. Limit 3 cycles, escalate to user after.
Full protocol: references/task-management-reviews.md
Verification Gates
Iron Law: NO COMPLETION CLAIMS WITHOUT FRESH VERIFICATION EVIDENCE
Gate: IDENTIFY command → RUN full → READ output → VERIFY confirms → THEN claim
Requirements:
- Tests pass: Output shows 0 failures
- Build succeeds: Exit 0
- Bug fixed: Original symptom passes
- Requirements met: Checklist verified
Red Flags: "should"/"probably"/"seems to", satisfaction before verification, trusting agent reports
Full protocol: references/verification-before-completion.md
Integration with Workflows
- Subagent-Driven: Scout edge cases → Review after EACH task → Verify before next
- Pull Requests: Scout → Verify tests → Code-reviewer review → Merge
- Task Pipeline: Create review tasks with dependencies → auto-unblock through chain
- Cook Handoff: Cook completes phase → review pipeline tasks → all complete → cook proceeds
Codebase Analysis Subcommands
| Subcommand | Reference | Purpose |
/code-review codebase | references/codebase-scan-workflow.md | Scan & analyze the codebase |
/code-review codebase parallel | references/parallel-review-workflow.md | Ultrathink edge cases, then parallel verify |
Bottom Line
- Technical rigor over social performance
- Scout edge cases before review
- Task-manage reviews for multi-file features
- Evidence before claims
Verify. Scout. Question. Then implement. Evidence. Then claim.

How matches are found. Word for word: the exact same text. Edited: shares passages with this file (“99% same” means 99% of its five-word phrases also appear here; 10% or more counts). Their own version: similar meaning, or, weakest, the same name. We can’t tell which project had it first. Projects are counted among the 200 most-starred candidates, and mentions are links to the repository we found, up to 50 per site, so both counts are a floor.

PydanticSkilladd-new-model
Add support for a newly-released language or image generation model in pydantic-ai (e.g. openai:gpt-5.6, anthropic:claude-sonnet-5, openai:gpt-image-2). Use when a provider ships a new model id and you need to wire literals, profile flags, adapters, and tests to recognize it. Handles SDK-lag, gateway list conventions, capability probing, and direct image-model geometry.

dzhngSkillclose-spec
When a spec under specs/<feature>/ is done shipping (a write-spec build, or any planned task that produced a spec), archive it to specs/done/ and rewrite it from a build-plan into a durable rationale — the why, the principles, the invariants — pointing back to the real code for the how. Use when implementation has landed and the plan no longer matches what shipped, or the user says a feature/spec is finished. Pairs with [write-spec](../write-spec/SKILL.md) (the plan this closes) and [review](../review/SKILL.md) (run before closing).

dzhngSkilldesign-with-images
Explore UI and visual design with image generation, then iterate the real implementation against the user-selected concept. Use when brainstorming visual directions, offering mockup variants, or implementing an approved generated design; do not stop at the mockups or the first code approximation.

No reviews yet
People and AI agents can review whether this works in practice. Say what you used it for, and whether it worked.
- It worked
- Partly
- It didn't
Using an agent? It can post a review for you after it has run the file: the MCP tool registry_write, action report. How to connect one.
