skills: Instructions file for Claude Code

AGENTS.md

skills AGENTS.md is an instructions file for Claude Code, Codex, OpenCode from zaks-io/skills. It costs 1,169 tokens per session, scanned A, original, MIT.

An instruction guide for a repository that publishes reusable workflow skills for coding agents. It explains the repository layout, shared rules, and required checks.

In plain words
What is it for?
Use it when editing or reviewing skills, agent configuration, workflow documentation, plugin files, or repository guidance.
Why use it?
It gives agents one source of guidance so published skills, adapters, and internal workflow documents stay aligned.

Instructions file for Claude CodeCodexOpenCode

Written for Claude Code and Codex and OpenCode: ${CLAUDE_PLUGIN_ROOT} variable, but also the file is AGENTS.md. Also seen: mentions .claude-plugin; mentions CLAUDE.md; mentions subagents.

This is zaks-io/skills's own configuration. It tells Claude Code, Codex and OpenCode how to work on skills 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 skills configures →

Runs only inside a plugin — its command needs a path that Claude Code sets for a plugin’s own hooks and for nothing else, and the catalogue could not identify which plugin ships it.

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

skills AGENTS.md 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 — 102 lines — stays where its author put it; the contents beside it link to each section on GitHub.

zaks-io-skills Agent Guide

Purpose

This repo publishes shared workflow skills for engineering agents. The skills help agents set up repo-local workflow config, move issue-tracked work through implementation, review code and PRs, and create or update PRs consistently.

AGENTS.md is the source of truth for agent guidance. Keep CLAUDE.md as a one-line @AGENTS.md import so Claude Code and other agents read the same content.

Map

  • skills/<skill>/SKILL.md: portable skill instructions. Each skill should have one job and one top-level heading.
  • skills/<skill>/agents/openai.yaml: Codex adapter and trigger fixture for the matching skill.
  • .claude-plugin/plugin.json: Claude Code plugin manifest.
  • .agents/: repo-internal runbooks that are not published by skill discovery.
  • .agents/skill-maintenance.md: instruction authoring and behavioral validation.
  • agents/<agent>.md: Claude Code sub-agent definitions for the few workflow roles that benefit from isolated context.
  • skills/ziw-setup/references/workflow.md: the shared workflow contract (roles, lifecycle, states, labels, ticket body, rules). One home per rule.
  • skills/ziw-setup/references/config-template.md: template for downstream docs/agents/workflow/config.md and planner.json.
  • skills/ziw-code-review/references/: review support material.
  • docs/planner-internals.md: maintainer notes for planner evidence, collection, and compatibility.
  • docs/agent-workflow.md: how the skills fit together and the design rules for changing them.
  • docs/skill-distribution.md: source-backed policy for project skills, plugins, global installs, lockfiles, and downstream refresh PRs.
  • docs/skill-portfolio.md: publishable skill surface, trim criteria, and keep/remove rationale.
  • docs/agents/workflow/config.md: repo-local workflow lookup table. Read it before running ziw-* workflow skills in this repo.
  • scripts/check-skills.mjs: structural validation and repo invariants.
  • scripts/planner-schema/: planner JSON Schema source. Run pnpm generate:planner-contract after edits; pnpm check verifies generated schema and standalone validator freshness.
  • scripts/update-downstream-skills.mjs: discovers downstream skills-lock.json consumers, runs project-scope skill updates, and reports repos needing PRs.
  • scripts/workflow-contract.mjs: pure workflow decision helpers covered by node --test.
  • README.md: user-facing overview, quick start, and install commands.

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.
