Claude Powerpack
Essential productivity tools for Claude Code: deep codebase analysis agent, expert consultation docs, code extraction, PR workflows, and more
Features
Code Researcher Agent
Deep codebase analysis specialist for answering complex questions about code:
- Execution Flow Tracing: Follows call chains across frontend/backend boundaries through every layer
- Usage Pattern Finding: Quantified counts with file:line references
- Architecture Mapping: Full hierarchies with ASCII diagrams
- Inconsistency Auditing: Severity-rated findings across all consumer layers
- Structural Search: ast-grep for AST-level pattern matching
- Git Investigation: History, blame, evolution tracking
Debrief Skill
End-of-session learning capture with progressive disclosure:
- Session Analysis: Scans conversation for mistakes, corrections, discoveries, and decisions
- Doc Audit: Checks CLAUDE.md, .claude/rules/, and project docs to avoid duplicates
- Progressive Disclosure: High-signal one-liners to CLAUDE.md, detailed knowledge to .claude/rules/
- Stale Entry Pruning: Identifies entries duplicated by docs, enforced by toolchain, outdated, or left as session debris
- Token Discipline: Enforces CLAUDE.md under 300 lines, routes domain knowledge to scoped rules
- User Approval: Presents all proposed changes before writing anything
Deep Interview Skill
Structured requirements gathering via interactive interviews:
- 7-Phase Process: Context → Scope → Approach → Priority → Details → Technical → Timeline
- GitHub Integration: Pulls issue context before asking questions
- PRD Generation: Auto-generates PRD with decision log and implementation checklist
- Best Practices: Multi-select questions, tradeoff presentation, stakeholder probing
Trim PR Skill
Pre-merge PR cleanup to trim accumulated complexity:
- Cruft Detection: Debug logging, commented code, unused imports, TODOs for done work
- Over-Engineering Check: Premature abstractions, dead code paths, speculative features
- Framework-Agnostic: Auto-detects Node.js, Python, Go, Rust for verification
- Risk-Rated Output: Change summary with Low/Medium/High risk assessment
Update PR Skill
Create comprehensive PR descriptions that document every meaningful change:
- Systematic Review: Inventories ALL changed files and commits
- Multi-Category: Features, bug fixes, tests, docs, config - nothing missed
- Structured Output: Organized sections for user impact and technical details
- GitHub Integration: Updates PR via
gh pr edit
Analyze Dependencies Skill
Changelog analysis for dependency updates with actionable recommendations:
- Multi-Mode: Preflight (before updating), post-update (after), or specific package research
- Ecosystem Support: npm and NuGet (auto-detected from project files)
- Multi-Source Research: Context7, GitHub Releases API, WebSearch, WebFetch
- Codebase Cross-Reference: Greps for actual usage of deprecated/changed APIs
- Structured Report: Breaking changes, new features, deprecations, security fixes, recommendations
Ask Expert Skill
Create comprehensive technical consultation documents for external expert review:
- Code Extraction: Full files, line ranges, or git diffs
- Size Tracking: Real-time progress with 125KB limit warnings
- Multi-file Support: Batch multiple files in single command
- Section Organization: Structured markdown headers
- Git Integration: Extract changes between branches/commits
- Config Files: Reusable extraction plans via JSON

Usage
Code Researcher Agent
The code-researcher agent activates when Claude Code spawns a sub-agent for deep codebase analysis. It's used automatically by the Agent tool when research questions match its description. See Skills Included for example prompts.
Debrief Skill
Run at the end of a session to capture learnings. Claude reviews the conversation, identifies what was learned, audits existing docs, and proposes targeted updates. See Skills Included for example prompts.
