Claude Code Power Pack

12 slash commands, 4 subagents, and 3 CLAUDE.md templates for real engineering workflows — code review, testing, security, performance, migrations, incident response, and onboarding. Not affiliated with or endorsed by Anthropic; built for use with Claude Code.

Get it

Everything in this repo is free to clone and use right now — git clone or download the zip. If it saves you time, a suggested $12 in crypto is appreciated (no payment account is needed; native coins work on Ethereum, Base, Arbitrum, Optimism, Polygon, or BNB, and USDC works on Ethereum, Base, Arbitrum, Optimism, or Polygon):

No payment login, license key, or tracking. Pay if and when it's useful to you. A GitHub account is required only if you want to claim the private Pro repository.

Sponsors get 3 bonus commands/agents (/changelog-gen, /release-checklist, an architecture-reviewer subagent) in a private companion repo. After sending any amount, open a "Claim Pro access" issue with the chain and transaction hash — a GitHub Action checks it on-chain automatically (usually within a couple minutes) and invites your GitHub account as a collaborator. No email or manual step on my end.

Every command and agent here follows the same rules: concrete file:line findings over vague advice, evidence over guessing, and no padding sections with "N/A" just to look thorough. These are the same standards a careful senior engineer would hold a review to.

Install

Project-level (recommended — scoped to one repo):

./install.sh /path/to/your/project

Or manually, copy what you want:

cp commands/*.md  ~/.claude/commands/     # or .claude/commands/ inside a project
cp agents/*.md     ~/.claude/agents/       # or .claude/agents/ inside a project

Then pick a CLAUDE.md template from claude-md-templates/ matching your stack, copy it to your repo root as CLAUDE.md, and fill in the bracketed sections.

What's included

Slash commands (commands/)

Command	Use it for
/code-review	Deep review of the current diff — correctness, security, performance, test coverage
/test-gen	Generate missing tests for a file or function, run and verify them
/refactor-safe	Refactor with behavior-preservation as a hard constraint
/pr-description	Write a PR description reviewers actually want to read
/bug-repro	Turn a vague bug report into a minimal, confirmed repro
/security-audit	OWASP-style pass over a diff or path
/perf-audit	Find real performance hotspots, not theoretical ones
/dependency-audit	Audit dependencies for CVEs, staleness, and bloat
/onboarding-doc	Generate an onboarding doc for an unfamiliar codebase
/incident-postmortem	Structured, blameless incident postmortem
/api-docs	Accurate API reference generated from actual code, not stale docstrings
/migration-plan	Plan a DB/schema migration that won't take down production

Subagents (agents/)

Agent	Role
code-reviewer	Read-only reviewer for diffs/branches — correctness, security, performance
test-writer	Writes and runs tests until they pass, reports coverage gaps honestly
security-auditor	OWASP-style security pass, exploitability-ranked findings
refactor-planner	Plans safe, incremental refactor steps before any code is touched

CLAUDE.md templates (claude-md-templates/)

Node/TypeScript, Python, and Go — structured starting points covering commands, conventions, architecture, and the "things that will bite you" section that actually matters most.

Customizing

Every file here is plain markdown. Edit freely — these are a strong starting point tuned for real engineering rigor, not a black box. If a command's checklist doesn't match how your team works, cut what doesn't apply.
