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 | $0.00044 | $0.00249 |
| Opus 5.5 | $0.00018 | $0.00100 |
| Sonnet 5.5 | $0.00009 | $0.00050 |
| Haiku 4.5 | $0.00004 | $0.00025 |
Grade A, and why
fix-gh-actions 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 1mo 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
Fix GitHub Actions
Use GitHub metadata, local repo inspection, and local reproduction where possible.
Workflow:
- Identify the failing workflow, job, and step.
- Classify the failure as flake, infra, or real before any action. When many unrelated jobs fail at once, check https://www.githubstatus.com first.
- Before a retry, check the base with
git merge-base --is-ancestor origin/main HEAD. On a stale base, rebase instead of a retry. - Retry a suspected flake one time. A second identical failure is a defect.
- Inspect the relevant workflow files, scripts, jq filters, and code paths.
- Reproduce locally when feasible.
- Fix the smallest root cause rather than papering over symptoms.
- Re-run targeted validation and report residual risk.
If the failure is in action/ or action.yml, also use github-action-review.
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.

fix-gh-actions is a skill published in the GitHub repository fallow-rs/fallow (5,273 stars, last pushed today), licensed MIT. It adds 44 tokens to every session and 249 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.
