fallow: Skill for Claude Code

.agents/skills/ship/SKILL.md

ship is a skill for Claude Code, Codex from fallow-rs/fallow. It costs 42 tokens per session (2,004 once invoked), scanned A, original, MIT.

A release checklist for moving reviewed Fallow work onto the main branch and confirming that the merged code is healthy. It covers checks, commits, protected-branch merging, CI, generated files, and repository cleanup.

In plain words
What is it for?
It is for shipping or merging approved work, rerunning quality gates, monitoring merged-commit CI, checking the final tree, and leaving local repositories synchronized and clean.
Why use it?
It reduces the risk of shipping unreviewed changes, missing companion files, unnoticed merge problems, or code whose required checks are still running.

Skill for Claude CodeCodex

Written for no agent in particular: nothing here depends on one. Also seen: installed under .agents/ (shared by several agents).

This is fallow-rs/fallow's own configuration. It tells Claude Code and Codex how to work on fallow itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything fallow configures →

Needs its repository: it runs a file that does not travel with it, so clone the repository first. The line is node scripts/ship-wait-checks.mjs --pr <number> --head <full sha> --min-checks <count>.

About the project

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.

Token cost

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.

Security

Grade A, and why

ship 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.

How it starts

The opening of the file, as written. The whole thing — 145 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Ship

  1. Confirm the branch and diff exactly match the reviewed scope. To put the branch on the current base, run node scripts/ship-rebase.mjs --pr <number> --push, also for one pull request. Do not rebase by hand. The script compares the result with a merge and checks each version constant. A failed manual rebase --continue leaves commits on a detached HEAD.
  2. Re-run the required checks from docs/development/quality-gates.md.
  3. Verify that public contracts and generated files are pushed. Merge each companion change into the default branch of its repository (for example fallow-docs main). A pushed feature branch is not enough: the release then must merge it. When the merged change touches npm/fallow/skills, run node scripts/sync-skills-companion.mjs and push the fallow-skills commit that it prepares.
  4. Create signed conventional commits only.
  5. Merge through the repository's current protected-main workflow.
  6. Monitor the merged commit until required CI completes. Use node scripts/ship-wait-checks.mjs --commit <full sha> --min-checks <count> --follow-main, with the run count of a recent push to main. A newer push to main cancels the runs of the merged commit. With --follow-main, the script then waits for the newest commit of origin/main that contains the merged commit, and prints one line for each move. On a busy main, new pushes can cancel each long run, and the wait can time out with pending runs. Then do not start the same wait again. For each workflow without a pass, watch its newest in-progress run on a commit that contains the merged commit (gh run watch <run id> --exit-status). Before you retry a failed job, confirm that the branch contains the current base (git merge-base --is-ancestor origin/main HEAD). A second identical failure is a defect, not a flake: diagnose it instead of a third retry.
  7. Inspect the merged tree for conflict markers and generated drift. Then run git diff <reviewed head> <merge commit>. A pull request that merged after your last rebase shows there, also when it did not conflict. Read each hunk in a file that your pull request changed. Such a merge can make your code, a comment or a doc wrong without a text conflict. Fix that in a follow-up pull request.
  8. Return every touched checkout to a clean, synchronized state.

Do not call work complete while required merged-commit workflows are still running.

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.
