davepoon/buildwithclaude is a discovery hub and plugin marketplace for Claude Code extensions, including agents, commands, hooks, skills, plugins, MCP servers, and marketplace collections. Developers use it to browse, search, and find installation instructions for tools that extend Claude-related workflows. Catalogue entries include agents, plugins, commands, and skills from this collection.
Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

A badge with what this costs and how it scanned, read live from this page, so it follows the numbers instead of freezing them. Markdown for a README, HTML for a documentation site or a project page.

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00009 | $0.00371 |
| Opus 5 | $0.00005 | $0.00186 |
| Sonnet 5 | $0.00002 | $0.00074 |
| Haiku 4.5 | $0.00001 | $0.00037 |
Grade A, and why
check scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured today.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
What it actually says
Run project validation checks and resolve any errors found.
Process:
-
Detect Package Manager (for JavaScript/TypeScript projects):
- npm: Look for package-lock.json
- pnpm: Look for pnpm-lock.yaml
- yarn: Look for yarn.lock
- bun: Look for bun.lockb
-
Check Available Scripts:
- Read package.json to find check/validation scripts
- Common script names:
check,validate,verify,test,lint
-
Run Appropriate Check Command:
-
JavaScript/TypeScript:
- npm:
npm run checkornpm test - pnpm:
pnpm checkorpnpm test - yarn:
yarn checkoryarn test - bun:
bun checkorbun test
- npm:
-
Other languages:
- Python:
pytest,flake8,mypy, ormake check - Go:
go test ./...orgolangci-lint run - Rust:
cargo checkorcargo test - Ruby:
rubocoporrake test
- Python:
-
-
Fix Any Errors:
- Analyze error output
- Fix code issues, syntax errors, or test failures
- Re-run checks after fixing
-
Important Constraints:
- DO NOT commit any code
- DO NOT change version numbers
- Only fix errors to make checks pass
If no check script exists, run the most appropriate validation for the project type.
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

check is a command published in the GitHub repository davepoon/buildwithclaude (3,415 stars, last pushed yesterday), licensed MIT. It adds 9 tokens to every session and 371 once invoked, about $0.0000 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-05.
Other commands, from other repositories
work-flow-feature
Complete workflow for developing a new feature, from exploration to merge.
plan-execute
Execute a validated plan: worktree isolation, TDD scaffolding, level-based parallel agents, quality gate with smoke test, PR creation and merge. Handles everything through to merged PR.
tdd
Run the test-driven development workflow: write failing tests first, then the minimal code to pass.
fix-issue
Fix a GitHub issue — reproduce it as a failing test before touching source (stop if it cannot be reproduced), check ARCHAEOLOGY for the guard that should have caught it, fix minimally, run the tiers, independent review, changelog, PR referencing the issue, machine-produced checklist.
husky
Sets up and manages Husky Git hooks by configuring pre-commit hooks, establishing commit message standards, integrating with linting tools, and ensuring code quality on commits.
create-pr
Streamlines pull request creation by handling the entire workflow: creating a new branch, committing changes, formatting modified files with Biome, and submitting the PR.
