harness: Skill for Claude Code

.agents/skills/check-deps/SKILL.md

check-deps is a skill for Claude Code, Codex from boldblackai/harness. It costs 95 tokens per session (2,224 once invoked), scanned A, original, MIT.

A dependency update check for versions pinned in the project's harness Dockerfiles. Dockerfiles are instructions for building the project's container environments.

In plain words
What is it for?
Use it to check packages and tools including coding agents, GitHub CLI, cosign, uv, and pnpm, then compare pinned versions with available releases.
Why use it?
It shows whether the fixed versions used to build those environments are outdated.

Skill for Claude CodeCodex

Which agent this was written for is unclear — built for hermes-agent. Also seen: installed under .agents/ (shared by several agents); built for hermes-agent; mentions OpenCode.

This is boldblackai/harness's own configuration. It tells Claude Code and Codex how to work on harness 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 harness 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

check-deps scanned grade A with 1 finding 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.

Not a fault in itself. Listed so you know the mod talks to something, and to what.

Dependency Version Check

This project pins nine external dependencies across its Dockerfiles. Check each one for updates and report what's current vs. what's available.

Dependencies to check

Dep File What's pinned How to find latest
@earendil-works/pi-coding-agent Dockerfile ~L56 npm version in pnpm install -g @earendil-works/pi-coding-agent@<VER> npm show @earendil-works/pi-coding-agent version
opencode-ai Dockerfile.opencode ~L6 npm version in pnpm install -g opencode-ai@<VER> npm show opencode-ai version
hermes-agent Dockerfile.hermes ~L91 git tag in --branch <TAG> gh release list --repo NousResearch/hermes-agent --limit 5
gh (GitHub CLI) Dockerfile ~L5 ARG GH_VERSION=<VER> gh release list --repo cli/cli --limit 5
cosign Dockerfile.hermes ~L12 ARG COSIGN_VERSION=<VER> gh release list --repo sigstore/cosign --limit 5
uv Dockerfile.hermes ~L10–11 ARG UV_VERSION=<VER> + ARG UV_DIGEST=sha256:... gh release list --repo astral-sh/uv --limit 5
pnpm Dockerfile ~L51 version in corepack prepare pnpm@<VER> npm show pnpm version
mise Dockerfile ~L61–65 ENV MISE_VERSION=<VER> + MISE_AMD64_SHA256 / MISE_ARM64_SHA256 checksums gh release list --repo jdx/mise --limit 5
debian:stable-slim Dockerfile L1 digest in FROM debian:stable-slim@sha256:... docker manifest inspect debian:stable-slim — see note below

Steps

  1. Read all pinned versions in parallel — use grep or Read on the relevant Dockerfiles. Extract:
    • npm package versions (pattern: @<VERSION>)
    • GitHub release ARGs (pattern: ARG <NAME>_VERSION=)
    • hermes-agent git tag (pattern: --branch <tag>)
    • uv digest (pattern: ARG UV_DIGEST=sha256:)
    • debian digest (pattern: FROM debian:stable-slim@sha256:)
    • pnpm version (pattern: corepack prepare pnpm@<VER>)
    • mise version + checksums (pattern: ENV MISE_VERSION= plus MISE_AMD64_SHA256 / MISE_ARM64_SHA256)

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.

check-deps is a skill published in the GitHub repository boldblackai/harness (10 stars, last pushed 5d ago), licensed MIT. It adds 95 tokens to every session and 2,224 once invoked, about $0.0005 per session on Opus 5. A static security scan graded it A with 1 finding (makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
