Lean (low-token budget) starter
Under 1.5k tokens of overhead per turn
Install
Run in your project root. Existing files are never overwritten (unzip -n / [ -e … ] skip them). Review AGENTS.md and fill in the <placeholders>.
$ curl -fsSL https://agentrigs.dev/starters/agentrigs-lean.zip -o agentrigs-starter.zip && unzip -n agentrigs-starter.zip && chmod +x .claude/hooks/guard.sh && rm agentrigs-starter.zip $ npx degit obra/superpowers/skills/systematic-debugging .claude/skills/systematic-debugging $ npx degit obra/superpowers/skills/verification-before-completion .claude/skills/verification-before-completion
Or download agentrigs-lean.zip (5 files). Skills are fetched from their source repos with npx degit.

# Project
<one line: what this is and the main language>
## Commands
- Test: `<cmd>` · Lint: `<cmd>`
## Rules
- Small diffs. Run tests before saying done.
- Ask before adding dependencies.
- Never read secrets or run destructive commands.
## Workflow
1. Restate the task in one line and list the files you expect to touch.
2. Make the smallest change that works; keep diffs reviewable.
3. Run the checks below before saying you're done, and show the output.
4. If something is ambiguous, ask one precise question instead of guessing.
## Safety
- Never read or print secrets (.env, keys, ~/.ssh). Ask for values instead.
- No destructive commands (rm -rf, force-push, reset --hard) without explicit approval; the guard hook blocks them anyway.
- Don't add dependencies, services or paid APIs without asking.

## Install
1. Unzip into your repo root (`unzip -n` won't overwrite existing files).
2. `chmod +x .claude/hooks/guard.sh` (needs `jq`).
3. Fill in the <placeholders> in AGENTS.md.
4. Install the recommended skills (third-party code, so review first):
```bash
npx degit obra/superpowers/skills/systematic-debugging .claude/skills/systematic-debugging
npx degit obra/superpowers/skills/verification-before-completion .claude/skills/verification-before-completion
```
Optional MCP servers (each adds context tax every turn):
```bash
claude mcp add --transport http context7 https://mcp.context7.com/mcp
```
Codex / Cursor / other harnesses read AGENTS.md directly; Claude Code reads CLAUDE.md, which imports AGENTS.md.

Claude Code pays for CLAUDE.md plus the imported AGENTS.md (~234 tok of instructions); Codex reads AGENTS.md alone (~203 tok). Index median: 2.3k tok. How we measure.

Recommended skills
Use when encountering any bug, test failure, or unexpected behavior, before proposing fixes
Use when about to claim work is complete, fixed, or passing, before committing or creating PRs - requires running verification commands and confirming output before making any success claims; evidence
