warren: Skill for Claude Code

.agents/skills/os-eco-dep-sync/SKILL.md

os-eco-dep-sync is a skill for Claude Code, Codex from jayminwest/warren. It costs 69 tokens per session (1,943 once invoked), scanned A, original, MIT.

A repository-specific guide for updating the Warren project’s published os-eco command-line tool dependencies and Docker image version pins.

In plain words
What is it for?
Use it to check published versions, update the relevant dependency files, run validation, and open a pull request.
Why use it?
It prevents the project from using mismatched or outdated tool versions across its package lockfile and container setup.

Skill for Claude CodeCodex

Written for no agent in particular: nothing here depends on one. Also seen: mentions CLAUDE.md; installed under .agents/ (shared by several agents); $skill-name invocation.

This is jayminwest/warren's own configuration. It tells Claude Code and Codex how to work on warren 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 warren configures →

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

os-eco-dep-sync 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 9d 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.

os-eco-dep-sync

Use this skill inside the warren repo when you need to confirm warren is running the newest published versions of the other os-eco tools and bump it if not. Warren is the only ecosystem consumer, and it tracks the rest of os-eco across two surfaces that must stay in lockstep:

  1. npm dependencies in package.json (+ bun.lock): @os-eco/burrow-cli and @os-eco/plot-cli. These are what warren builds and imports against — consumed as published registry packages, not links.
  2. Global CLI pins in the Dockerfile bun install -g block: all six bundled CLIs — @os-eco/burrow-cli, @os-eco/plot-cli, @os-eco/canopy-cli, @os-eco/seeds-cli, @os-eco/mulch-cli, @os-eco/sapling-cli — that back warren's opt-in features at runtime.

"Latest" always means the published npm version (npm view ... version), never the local sibling working tree.

The burrow double-pin invariant. @os-eco/burrow-cli (and plot-cli) appears in both surfaces. Bun.spawn resolves ./node_modules/.bin/burrow before PATH, so bumping only the Dockerfile is a silent no-op — the supervisor keeps running the lockfile copy. The two pins MUST be identical. See CLAUDE.md → "Relationship to burrow".

Pre-flight

cd warren                         # this skill operates only on the warren repo
git status                        # MUST be clean before you start
command -v bun npm git gh         # gh optional (only for the PR step)

If the tree is dirty, stop and let the user commit or stash first — this skill ends in a focused, reviewable commit and a noisy tree defeats that.

Read the current pins so you know the starting point:

grep '@os-eco/' package.json
grep '@os-eco/' Dockerfile

Procedure

1. Discover the latest published version of each tool

for t in burrow plot canopy seeds mulch sapling; do
  printf '%-8s %s\n' "$t" "$(npm view @os-eco/$t-cli version)"
done

If inputs.package was given, restrict the loop to that one tool. Record each latest. Compare against the pins printed in pre-flight; anything behind is a bump target. If every surface already matches latest, report "warren is up to date" and stop — do not create an empty commit.

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.
