skill-forge AGENTS.md

skill-forge AGENTS.md is an instructions file for Codex, OpenCode from pavelzw/skill-forge. It costs 613 tokens per session, scanned A, original, BSD-3-Clause.

Repository instructions for maintaining conda packages that contain coding-agent skills. Skills are instruction files that help an AI agent work with a specialized topic or tool.

In plain words
What is it for?
Use them when changing the repository structure, adding or updating mirrored skills, or configuring automatic updates for skills fetched from remote sources.
Why use it?
They explain where skill files live, how to mirror skills from skills.sh, and how to keep mirrored skills updated. This avoids inconsistent package contents and missed update automation.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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

skill-forge 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 4d 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.

Project Summary

This repository contains conda packages for coding agent skills.

Structure

"Skills" are text files that AI-based coding agents can read to enhance their understanding of a complex topic or tool, like an internal library or company-specific guidelines and knowledge. They're usually structured as markdown files with brief documentation, instructions, code examples, and usage guidelines. A skill may reference additional markdown files in a references/ subdirectory that are read on demand. Every skill is shipped in a conda package located in share/agent-skills/<skill>/SKILL.md (plus additional files).

Mirroring from skills.sh

When mirroring a skill from https://skills.sh/, start with the example in examples/mirror-skills.sh. You then need to look into the repository and find the actual skill directory.

Update Strategies for Mirrors

If you build a skill that fetches data from a remote source, please also add it to .github/workflows/autobump.yml with appropriate update strategies.

  • github-latest-release: Use this strategy if the repository has releases and the latest release is somewhat recent.
  • git-main: Use this strategy otherwise.

Updating skill contents

When the user asks you to update the content of a skill, follow these steps:

  1. Check out the latest version of the tool or API that the skill is based on to a temporary location.
  2. Investigate which parts of the skill still accurately reflect the current state of the tool or API and which parts need to be updated or added to the skill.
  3. Apply the minimal viable update to the skill's content. This means: a) NEVER change information in the skill that is still accurate, exhaustive, correct, and up-to-date. b) ONLY change information that is outdated, incorrect, or missing. c) Often times, this means edits will be local to a subsection or a few paragraphs, or new subsections will be added.
  4. If there is a PROMPT.md next to the recipe.yaml, read that file and also include it in how you update the skill.

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.
