Fallow is a command-line static-analysis tool that builds a dependency graph of TypeScript and JavaScript code to identify unused code, duplication, circular dependencies, complexity hotspots, boundary violations, and styling drift. It is for developers reviewing codebases and verifying changes, with catalogue entries that add agent, editor, and workflow integrations.

What it costs to keep this loaded
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 | $0.00047 | $0.00482 |
| Opus 5.5 | $0.00019 | $0.00193 |
| Sonnet 5.5 | $0.00009 | $0.00096 |
| Haiku 4.5 | $0.00005 | $0.00048 |
Grade A, and why
open-draft-pr scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 8d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
What it actually says
Open Review PR
This skill keeps its historical file/name for compatibility, but fallow PRs are ready for review by default. Do not open draft PRs unless the user explicitly asks for a draft.
Workflow:
- Review the changed files and confirm the scope.
- Run the smallest relevant validation for the touched area.
- Prepare a concise conventional commit message.
- Commit with
-S -s(signature and DCO sign-off) if committing is requested. - Push the branch. GitHub refuses a PR for a branch with no commits; make an intentional empty coordination commit before the first push when the branch is fresh.
- Write the PR body to a file and run the CI deferral check on it:
PR_BODY="$(cat body.md)" GITHUB_REPOSITORY=fallow-rs/fallow node .github/scripts/check-pr-deferrals.mjs. The check fails a body that defers work without an issue link, for example a "Follow-up" or "Not in this change" section. Link an issue, or add "No follow-up planned." to an intentional non-goal. Call a docs change a companion fallow-docs PR, not a follow-up. - Open a ready PR with a high-signal conventional title and that body.
After a later body edit, do not rerun the failed commit-message job:
the
editedevent starts a new run with the new body.
Requirements:
- Use conventional commits.
- Use signed commits with a DCO sign-off:
git commit -S -s. - Use a descriptive non-
codex/branch name, for examplefeat/<slug>,fix/<slug>,refactor/<slug>,docs/<slug>, orchore/<slug>. - Do not pass
--drafttogh pr createunless the user explicitly asks for a draft. - Do not add AI attribution.
- Summarize validation honestly if some checks were not run.
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.

open-draft-pr is a skill published in the GitHub repository fallow-rs/fallow (5,273 stars, last pushed today), licensed MIT. It adds 47 tokens to every session and 482 once invoked, about $0.0002 per session on Opus 5.5. 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.

Skill "github" from Hmbown/Codewhale, covering github, when to use, setup, workflow and non-goals.
release
Cut a brooks-lint release: set the version in package.json, propagate it across all four plugin manifests and every version-bearing text file (README badges, docs site metadata), write the CHANGELOG entry, validate, then commit, push, tag, and publish the GitHub release. Triggers when the maintainer asks to "release"…
release-habit-hooks
Cut a new release of the habit-hooks packages. Use when asked to release, publish, or bump the version. Reviews what lands, enforces the in-sync versioning rule, validates the changelog, and drives the tag-triggered PyPI publish.
argot-setup
Set argot up for a repository end to end — audit its history, decide what should shape its voice, fit, verify the fit actually catches things, tune the rules its own history says are noisy, and wire the places it runs (pre-write hook, pre-commit, MCP, CI). One sitting, one decision at a time, each proposed with the…
bump-version
Bump the Logic-Lens version across all six metadata locations at once (package.json, the four plugin manifests, and the README badge), then validate. Use when cutting a release or when npm run validate reports a version mismatch.
release-docs
Diff-driven documentation sync after a release. Determines what source files changed, delegates changelog to zuvo:docs, updates only docs whose source changed. Flags: --dry-run, explicit range argument.
