Instructions file for Claude CodeCodexOpenCode

Written for Claude Code and Codex and OpenCode: Claude Code plugin machinery, but also the file is AGENTS.md. Also seen: mentions CLAUDE.md; mentions AGENTS.md.

This is powabase-ai/agent-skills's own configuration. It tells Claude Code, Codex and OpenCode how to work on agent-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 agent-skills 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

agent-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 6d 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.

How it starts

The opening of the file, as written. The whole thing — 104 lines — stays where its author put it; the contents beside it link to each section on GitHub.

AGENTS.md

Guidance for AI coding agents working on this repository (authoring and maintaining the skills). If you are an agent trying to use Powabase, you want skills/powabase/SKILL.md, not this file.

Note: CLAUDE.md is a symlink to this file.

    SKILL.md
    references/      # load-on-demand topic files

.claude-plugin/marketplace.json

Prerequisites & commands

Uses pnpm and the Node.js version in .node-version.

pnpm install            # install dependencies
pnpm test               # run the sanity tests
pnpm build:release      # build dist/*.tar.gz + dist/index.json (needs RELEASE_TAG, GITHUB_* env)

Before completing any task, run pnpm test.

Writing SKILL.md files

A skill is YAML frontmatter followed by Markdown instructions, per the Agent Skills Open Standard.

Frontmatter (required)

---
name: powabase
description: What this skill does AND when to use it (this is the trigger).
license: Apache-2.0
metadata:
  author: powabase
  version: "0.0.0" # x-release-please-version
---
Field Required Constraints
name Yes 1–64 chars. Lowercase alphanumeric + single hyphens. Must match the dir name.
description Yes 1–1024 chars. Must state what the skill does and when to use it.
license No License name.
metadata No Free-form. Include version: "0.0.0" with an # x-release-please-version comment so Release Please bumps it.

The description is the primary trigger — Claude reads it to decide whether to activate the skill, so pack it with concrete nouns/contexts. Do not put "when to use" only in the body; the body loads after triggering.

Changes

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.
