PR Review Chamber Skill

Capture, organize, and retrieve knowledge from PR reviews within project memory palaces.

When To Use

• Capturing PR review knowledge for future reference

• Building review pattern libraries from past reviews

When NOT To Use

• Quick self-reviews of trivial changes

• Automated CI checks that cover the review scope

Overview

The Review Chamber is a dedicated room within each project palace that stores valuable knowledge extracted from PR reviews. It transforms ephemeral PR discussions into persistent, searchable institutional memory.

Room Structure

review-chamber/ ├── decisions/ # Architectural choices from PR discussions ├── patterns/ # Recurring issues and their solutions ├── standards/ # Quality bar examples and coding conventions └── lessons/ # Post-mortems and learnings

Verification: Run the command with --help flag to verify availability.

Workflow Phases

Phase 1: Knowledge Detection

After a PR review completes, evaluate findings for knowledge capture:

Knowledge Detection Checklist

For each finding from sanctum:pr-review, evaluate:

• Novelty: Is this a new pattern or first occurrence?
• Applicability: Will this affect future PRs in this area?
• Durability: Is this architectural (capture) or tactical (skip)?
• Connectivity: Does it link to existing palace rooms?

Verification: Run the command with --help flag to verify availability.

Phase 2: Classification

Route findings to appropriate subrooms:

Finding Type Target Room Criteria

Architectural choice decisions/

BLOCKING + architectural context

Recurring issue patterns/

Seen before or likely to recur

Quality example standards/

Exemplifies coding standards

Learning/insight lessons/

Retrospective or post-mortem

Phase 3: Capture

Create structured entry with:

source_pr: "#42 - Add authentication" date: 2025-01-15 participants: [author, reviewer1, reviewer2] palace_location: review-chamber/decisions related_rooms: [workshop/auth-patterns, library/security-adr] tags: [authentication, jwt, security]

Decision Title

Decision

Chose JWT tokens over server-side sessions.

Context (from PR discussion)

• Reviewer asked: "Why not use sessions?"
• Author explained: stateless scaling requirements
• Discussion refined: added refresh token rotation

Captured Knowledge

• Pattern: JWT + refresh tokens for stateless auth
• Tradeoff: Complexity vs. horizontal scaling
• Application: Use for all API authentication

Connected Concepts

• [[auth-patterns]] - Updated with JWT best practices
• [[security-adr-003]] - Referenced this decision

Verification: Run the command with --help flag to verify availability.

Phase 4: Integration

After capture, update related palace rooms:

• Add bidirectional links to related entries

• Update tags in project palace index

• Notify if this contradicts existing entries

Usage Examples

Capture After PR Review

Automatic: sanctum:pr-review triggers capture

/pr-review 42

→ Review posted to GitHub

→ Knowledge capture evaluates findings

→ Significant decisions stored in review-chamber

Manual: Explicitly capture from PR

/review-room capture 42 --room decisions

Verification: Run the command with --help flag to verify availability.

Search Past Decisions

Find authentication decisions

/review-room search "authentication" --room decisions

Find patterns in a specific area

/review-room search "error handling" --room patterns --tags api

List recent entries

/review-room list --limit 10 --room standards

Verification: Run the command with --help flag to verify availability.

Surface Relevant Knowledge

When starting work in a code area:

Relevant Review Knowledge

Starting work in auth/ directory...

Past Decisions:

• [#42] JWT token decision → decisions/jwt-over-sessions
• [#67] Rate limiting pattern → patterns/api-throttling

Quality Standards:

• [#55] Error response format → standards/api-errors

Known Patterns:

• [#38] Token refresh edge case → patterns/token-refresh-race

Verification: Run the command with --help flag to verify availability.

Integration Points

With sanctum:pr-review

The review-chamber integrates after Phase 6 (Generate Report):

Verification: Run the command with --help flag to verify availability. Phase 6: Generate Report ↓ [HOOK] Evaluate findings for knowledge capture ↓ For each significant finding: ├── Classify into room type ├── Create ReviewEntry ├── Add to project palace └── Update connections ↓ Phase 7: Post to GitHub

Verification: Run the command with --help flag to verify availability.

With knowledge-intake

Uses the same evaluation framework:

Criterion Weight PR Review Application

Novelty 25% New pattern or first occurrence

Applicability 30% Affects future PRs in this area

Durability 20% Architectural vs tactical

Connectivity 15% Links to existing rooms

Authority 10% Senior reviewer or domain expert

With knowledge-locator

Extends search to include review-chamber:

python scripts/palace_manager.py search "authentication"
--palace project-name
--room review-chamber
--type semantic

Verification: Run python --version to verify Python environment.

Evaluation Rubric

Worth Capturing (Score ≥ 60)

• Architectural decisions with documented rationale

• Recurring patterns seen in 2+ PRs

• Security/performance critical findings

• Domain knowledge that explains business logic

• Convention changes that affect future code

Skip (Score < 60)

• One-off tactical fixes

• Style preferences without rationale

• Obvious bugs without pattern

• External dependency issues

• Temporary workarounds

CLI Reference

Capture knowledge from PR

/review-room capture <pr_number> [--room <room_type>] [--tags <tags>]

Search review chamber

/review-room search "<query>" [--room <room_type>] [--tags <tags>]

List entries

/review-room list [--room <room_type>] [--limit N]

View entry details

/review-room view <entry_id>

Export for documentation

/review-room export [--format markdown|json] [--room <room_type>]

Statistics

/review-room stats [--palace <palace_id>]

Verification: Run the command with --help flag to verify availability.

Best Practices

• Capture decisions immediately - Context is freshest right after review

• Link related entries - Build the knowledge graph

• Use consistent tags - Enable cross-project discovery

• Review periodically - Prune outdated entries

• Surface proactively - Show relevant knowledge when starting related work

Module Reference

• See modules/capture-workflow.md for detailed capture process

• See modules/evaluation-criteria.md for knowledge worth assessment

• See modules/search-patterns.md for query optimization

Troubleshooting

Common Issues

Command not found Ensure all dependencies are installed and in PATH

Permission errors Check file permissions and run with appropriate privileges

Unexpected behavior Enable verbose logging with --verbose flag
