OpenGAP is a framework-independent standard for defining AI agents as Git repositories, using files such as an agent manifest and identity document. It is intended for portable, version-controlled agents that can be adapted to systems such as Claude Code, OpenAI, LangChain, CrewAI, and AutoGen. The catalogue skills represent workflows and extensions built around this agent format.
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.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00065 | $0.00687 |
| Opus 5.5 | $0.00026 | $0.00275 |
| Sonnet 5.5 | $0.00013 | $0.00137 |
| Haiku 4.5 | $0.00006 | $0.00069 |
Grade A, and why
manage-skills 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 1mo 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 — 120 lines — stays where its author put it; the contents beside it link to each section on GitHub.

When to Use
When a user wants to find skills, install them, create new ones, or understand the skills system.
Verify Installation
After installing a skill, confirm it's available:
opengap skills list -d ./my-agent | grep "code-review"
Search Skills
# Search SkillsMP registry
opengap skills search "code review"
# Search GitHub
opengap skills search "pdf reader" --provider github
# Limit results
opengap skills search "testing" --limit 5
Install Skills
# Install from SkillsMP to agent-local skills/
opengap skills install code-review -d ./my-agent
# Install globally to ~/.agents/skills/
opengap skills install code-review --global
# Install from GitHub
opengap skills install owner/repo#skills/my-skill --provider github
List Skills
# Show all discovered skills (local + global)
opengap skills list -d ./my-agent
# Only agent-local skills
opengap skills list -d ./my-agent --local

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.
- 1mo ago First seen · 120 lines · 65 tokens per session scan A 0d81b5bd350f
manage-skills is a skill published in the GitHub repository open-gitagent/opengap (2,981 stars, last pushed 3mo ago), licensed MIT. It adds 65 tokens to every session and 687 once invoked, about $0.0003 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
