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.

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 | $0.00051 | $0.00656 |
| Opus 5 | $0.00026 | $0.00328 |
| Sonnet 5 | $0.00010 | $0.00131 |
| Haiku 4.5 | $0.00005 | $0.00066 |
Grade A, and why
dev-commit 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 2d ago.
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.
How it starts
The opening of the file, as written. The whole thing — 40 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Dev Commit
Make one intentional, verified commit without sweeping in unrelated work.
Commit Contract
- Check repository state with
git status --short --branch,git diff --stat, andgit diff. - Identify the files that belong to the requested change. Treat pre-existing user edits, local config, generated artifacts, dependency caches, build outputs, and unrelated formatting churn as out of scope unless the user explicitly includes them.
- Run appropriate validation before committing. Prefer the repo's targeted tests, lint, typecheck, build, or documented verification commands. Record skipped validation with the reason. In workspaces whose packages resolve against built artifacts, ensure install and build have run in that worktree (
npm ci,npm run build) before full validation or commit hooks; a fresh worktree with stale artifacts fails hooks for environmental reasons. - Stage only intended paths. Prefer explicit pathspecs such as
git add path/to/fileovergit add .. - Re-check with
git diff --cached --stat,git diff --cached, andgit status --short. - Write a concise conventional commit message:
<type>(optional-scope): <summary>. - Commit, then report the commit SHA, final status, validation commands, and any unstaged/untracked files left behind.
Guardrails
- Do not commit secrets, credentials,
.envfiles, local machine config, caches, coverage, logs, screenshots, or generated files unless the change explicitly requires them. - Do not stage another person's unrelated edits. If intended and unrelated changes are mixed in one file, use an interactive or patch-based staging flow and review the staged diff carefully.
- Do not amend, rebase, force-push, reset, or delete branches unless the user explicitly asks for that operation.
- If validation fails, stop before committing unless the user explicitly instructs you to commit with failing validation. Report the failing command and key output.
- If the repo has commit hooks, let them run. If a hook changes files, inspect and stage only intended hook outputs before retrying. If a hook fails, first rule out environmental causes (missing install, stale workspace build artifacts, concurrent test runs sharing resources) by re-running the failing package in isolation; do not treat an environmental failure as a code regression or "stop" condition until isolated runs still fail.
What ships with it
1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

dev-commit is a skill published in the GitHub repository codeaholicguy/ai-devkit (1,601 stars, last pushed 2d ago), licensed MIT. It adds 51 tokens to every session and 656 once invoked, about $0.0003 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 2026-08-30.
Other skills, from other repositories
tmux
Remote-control tmux sessions for interactive CLIs by sending keystrokes and scraping pane output.
summarize
Summarize or extract text/transcripts from URLs, podcasts, and local files (great fallback for “transcribe this YouTube/video”).
foundry-config-setup
Resolve missing setup caused by a hardcoded Foundry project endpoint or model in a sample. Use when a sample fails because it uses a placeholder/hardcoded projectendpoint (for example "https://your-project.services.ai.azure.com") or a hardcoded model instead of reading them from the environment.
complete-partial-pr
Evaluate and complete an issue or PR where the submitted patch fixes only a narrow symptom of the reported pain point. Use when a contribution may miss adjacent integration surfaces, provider/spec semantics, roundtrip behavior, tests, docs, or historical maintainer decisions.
hive.chart-creation-foundations
Required reading whenever any chart tool is available. Teaches the one-tool embedding contract (call chartrender → live chart appears in chat AND a downloadable PNG lands in the queen session dir), the ECharts (data viz) vs Mermaid (structural diagrams) decision, the BI/financial-grade aesthetic baseline (no…
peon-ping-log
Log exercise reps for the Peon Trainer. Use when user says they did pushups, squats, or wants to log reps. Examples - "/peon-ping-log 25 pushups", "/peon-ping-log 30 squats", "log 50 pushups".
