description	This skill should be used when the user asks to "build review skills", "generate review skills", "create review perspectives", "build review setup", "レビュースキルを生成", "レビュースキルをビルド", "レビューを作って", or after interview skill has populated the knowledge-base. This is the core of tailored-reviewer: it builds project-specific SKILL.md files that form a complete review system.

Build Review Skills

Generate a complete set of project-specific review SKILL.md files based on the knowledge-base.

Step 0: Environment Setup (MUST do first)

The current directory is the review data project (e.g., ~/review/rclc/). This directory contains:

• config.md — project configuration
• knowledge-base/ — collected project knowledge
• meta/ — metadata files (plugin-version-used.md, build-inputs.md, etc.)
• workspace/ — git clone of the actual project
• .claude/skills/ — generated skill files (output destination)

All paths in this skill are relative to this project root.

• meta/ means the project root's meta/, NOT .claude/skills/meta/
• knowledge-base/ means the project root's knowledge-base/
• Generated skills go to .claude/skills/{perspective-id}/SKILL.md

Prerequisites:

• knowledge-base/ directory exists with populated files
• config.md exists with project information
• workspace/ exists with project clone

Process

Step 1: Read Knowledge Base and Backtest Learnings

Read ALL files in knowledge-base/:

• project-context.md
• source-map.md
• design-principles.md
• implementation-principles.md
• roadmap.md
• bug-patterns.md
• pr-review-patterns.md
• team-context.md
• spec-sources.md

Note confidence levels. Low-confidence entries (<0.5) should be used cautiously in generated skills.

Also read backtest/learnings.md if it exists. This file contains detection patterns extracted from previous backtest misses — concrete checks that the review system failed to perform. Each learning specifies a target perspective and a check to add. These have the highest priority for inclusion in generated skills because they represent proven detection gaps validated against real bugs.

Step 2: Detect Tech Stack and Project Archetype

2a: Detect tech stack from workspace/ (package.json, requirements.txt, Cargo.toml, etc.):

• Frameworks: Next.js (Pages/App Router), React, Vue, Express, FastAPI, etc.
• Databases: PostgreSQL, MySQL, MongoDB, Redis, Prisma ORM, etc.
• Runtime: Node.js, Python, Go, Rust, etc.
• Infrastructure: Docker, Kubernetes, serverless, edge, etc.

2b: Classify archetype:

Signal	Archetype
Next.js/React/Vue + API routes	Web Application
gRPC/REST services + Docker/K8s	Backend Service / Microservice
Spark/Airflow/Kafka consumers	Data Pipeline
Swift/Kotlin + mobile frameworks	Mobile Application
C/C++/Rust + hardware interfaces	Embedded / Real-time
Large single repo + tight coupling	Legacy Monolith

Projects may match multiple archetypes. Include all that apply.

Step 3: Generate Technical Concern Perspectives

Read ${CLAUDE_PLUGIN_ROOT}/skills/build-skills/references/archetype-checklists.md (Technical Concern Perspectives section).

MANDATORY — generate ALL 8 of these perspectives. No exceptions. No substitutions. No skipping.

1. execution-flow
2. resource-management
3. concurrency
4. security
5. platform-constraints
6. implementation-quality
7. code-health (cognitive load + debt trajectory + design integrity + observability)
8. strategic-alignment (problem diagnosis + roadmap consistency)

1-6 are Technical Concerns (does the code work correctly?). 7-8 are Design Concerns (is the code maintainable and strategically sound?). All types are mandatory.

These are NOT alternatives to domain perspectives — they COEXIST with domain perspectives generated in Step 4. A project will have these 8 PLUS domain-specific perspectives.

Do NOT replace these 8 with project-specific perspectives (e.g., do not generate "shell-script-robustness" instead of "execution-flow"). Project-specific concerns go into domain perspectives in Step 4.

For each, read ${CLAUDE_PLUGIN_ROOT}/skills/build-skills/references/templates/technical-concern.md and use the template:

• Populate check items from archetype-checklists.md
• Overlay tech-stack-specific checks from ${CLAUDE_PLUGIN_ROOT}/skills/build-skills/references/tech-patterns/{stack}.md (if exists for detected stack)
• Inject high-impact patterns: read ${CLAUDE_PLUGIN_ROOT}/skills/build-skills/references/high-impact-patterns.md. For each pattern whose condition is met by the project (detected in Step 2), include it in the matching concern's check items. Only include patterns whose condition ID matches the project's characteristics.
• Inject backtest learnings: if backtest/learnings.md exists, include learnings whose Target perspective matches this concern. These are proven detection gaps and must be included as check items.
• Selective knowledge-base injection: only include knowledge-base entries relevant to this specific concern (NOT the full knowledge-base)
  • For concurrency: race condition patterns from bug-patterns.md, transaction-related principles
  • For security: auth-related patterns, data exposure rules
  • For implementation-quality: coding conventions from implementation-principles.md
  • For code-health: design-principles.md (architectural patterns, module boundaries), bug-patterns.md (areas with high churn indicating debt), implementation-principles.md (coding conventions)
  • For strategic-alignment: roadmap.md (planned features, migration plans), design-principles.md (architectural direction), project-context.md (project goals)
  • etc.

Verification: After generating, confirm you have exactly 8 files:

• .claude/skills/execution-flow/SKILL.md
• .claude/skills/resource-management/SKILL.md
• .claude/skills/concurrency/SKILL.md
• .claude/skills/security/SKILL.md
• .claude/skills/platform-constraints/SKILL.md
• .claude/skills/implementation-quality/SKILL.md
• .claude/skills/code-health/SKILL.md
• .claude/skills/strategic-alignment/SKILL.md

If any are missing, go back and generate them before proceeding to Step 4.

Step 4: Generate Domain Perspectives

Read archetype-checklists.md (Domain Perspective Archetypes section).

For each matched archetype:

1. Include all REQUIRED domain perspectives
2. Check CONDITIONAL perspectives against knowledge-base — include if relevant data exists
3. DO NOT duplicate what the 6 technical concern perspectives already cover
   • e.g., if "Authentication & Authorization" is already covered by the security concern, only generate a domain perspective if there are project-specific auth rules beyond standard security checks

For each domain perspective, read ${CLAUDE_PLUGIN_ROOT}/skills/build-skills/references/templates/domain-perspective.md and use the template:

• Fill in project-specific content from knowledge-base
• Convert bug-patterns.md entries → specific check items
• Convert pr-review-patterns.md entries → reviewer knowledge
• Convert design-principles.md → deviation detection rules
• Inject backtest learnings: include learnings whose Target perspective matches this domain perspective

Step 5: Write All SKILL.md Files

Write all generated skills to .claude/skills/{perspective-id}/SKILL.md. Generate review entry point, fact-check, design-critique, debate, and consolidation skills from their respective templates, filling in the FULL perspective list (technical + domain) and project name:

• Review entry point: read ${CLAUDE_PLUGIN_ROOT}/skills/build-skills/references/templates/orchestrator.md → write to .claude/skills/review-{project_name_slug}/SKILL.md (where {project_name_slug} is the project name lowercased, spaces/special chars replaced with hyphens). CRITICAL: The orchestrator template contains Steps 0 through Phase 4. Do NOT summarize or omit any steps. Every numbered step and phase must appear in the generated skill. In particular: Step 0.6 (base branch alignment), Step 0.7 (Spec Context Collection with AskUserQuestion), and Phase 4 (Cleanup) are frequently dropped by accident — verify they are present.
• Fact Check: read ${CLAUDE_PLUGIN_ROOT}/skills/build-skills/references/templates/fact-check.md
• Design Critique: read ${CLAUDE_PLUGIN_ROOT}/skills/build-skills/references/templates/design-critique.md
• Debate: read ${CLAUDE_PLUGIN_ROOT}/skills/build-skills/references/templates/debate.md
• Consolidation: read ${CLAUDE_PLUGIN_ROOT}/skills/build-skills/references/templates/consolidation.md

Step 6: Completeness Verification

Before finishing, verify:

Perspective Coverage (CRITICAL — failure here means restart Step 3):

• execution-flow/SKILL.md exists
• resource-management/SKILL.md exists
• concurrency/SKILL.md exists
• security/SKILL.md exists
• platform-constraints/SKILL.md exists
• implementation-quality/SKILL.md exists
• code-health/SKILL.md exists
• strategic-alignment/SKILL.md exists

Content Quality:

• Each technical concern has tech-stack-specific checks (not just generic)
• Domain perspectives don't duplicate technical concerns
• Knowledge-base injection is selective (each skill only has relevant KB entries)
• knowledge-base entries with unique patterns (bug hotspots, reviewer focus areas) are reflected
• Generated skills reference specific files/modules from the project, not just generic advice

Review Entry Point Completeness:

• Skill name is review-{project_name_slug} (NOT review-orchestrator)
• Description includes trigger phrases for the skill system
• Lists ALL generated perspectives (8 perspectives + domain)
• Step 0.6 fetches PR metadata (pr-meta.json with base branch), diff, info, and files; aligns workspace to PR base branch
• Step 0.7 Spec Context Collection is present — auto-fetches linked tickets AND asks user via AskUserQuestion
• Has Phase 1.5 with workspace verification AND PR diff reconciliation
• Has Phase 1.7 Design Critique
• Has Phase 2 Contradiction Detection
• Has Phase 3 Consolidation dispatch
• Has Phase 4 Cleanup — restores workspace to default_branch after review

Consolidation Completeness:

• Has MANDATORY File Output section at the TOP
• File path uses reviews/ directory
• Report format includes Design Critique section
• Report format includes workspace reconciliation drops in Fact-Check Log

Step 6: Run Debug-Review

Automatically invoke the debug-review skill to validate the generated skills. If debug-review reports issues, fix them and re-validate.

Step 7: Skill-Reviewer Validation (Optional)

If plugin-dev plugin is installed, invoke its skill-reviewer agent on each generated SKILL.md. If not installed, skip — debug-review provides sufficient validation.

Step 8: Record Metadata

IMPORTANT: All metadata files go in the meta/ directory at the PROJECT ROOT (next to config.md, knowledge-base/, workspace/). NOT in .claude/skills/meta/. The .claude/skills/ directory is ONLY for generated skill SKILL.md files.

• Write current tailored-reviewer version to meta/plugin-version-used.md
• Update meta/last-updated.md with generation timestamp
• Record build inputs: write meta/build-inputs.md with the hash (first 8 chars of sha256) of each reference file used during generation:

# Build Inputs
Generated: YYYY-MM-DD

## Reference File Hashes
- archetype-checklists.md: {hash}
- high-impact-patterns.md: {hash}
- templates/orchestrator.md: {hash}
- templates/technical-concern.md: {hash}
- templates/domain-perspective.md: {hash}
- templates/fact-check.md: {hash}
- templates/design-critique.md: {hash}
- templates/debate.md: {hash}
- templates/consolidation.md: {hash}
- tech-patterns/{stack1}.md: {hash}
- tech-patterns/{stack2}.md: {hash}
...

## Knowledge Base Hashes
- project-context.md: {hash}
- design-principles.md: {hash}
...

## Backtest Learnings
- backtest/learnings.md: {hash} (or "not present")

To compute hashes, run: shasum -a 256 <file> | cut -c1-8

This file is used by update-skills to determine which build inputs changed and target only affected skills for regeneration.

Output

Report to user:

• Number of perspectives generated
• List of perspective names with one-line descriptions
• Any warnings from debug-review
• Prompt: "Review skills generated. Run /review-{project_name_slug} from this project directory."
