SkillCorpus is an open-source ai agents skill for AI coding assistants such as Claude Code, Codex CLI, and ChatGPT, built by EverMind-AI. Open-source infrastructure that turns scattered SKILL.md files into curated, retrieval-ready agent-skill corpora—with retrieval and evaluation tooling included. It has 646 GitHub stars.
Yes. SkillCorpus passed SkillsLLM's automated security scan — a dependency vulnerability audit plus prompt-injection heuristics — with no high-severity issues. You can read the full report in the Security Report section on this page.
Clone the repository with "git clone https://github.com/EverMind-AI/SkillCorpus" and add it to your Claude Code skills directory (see the Installation section above).
SkillCorpus is primarily written in Python. It is open-source under EverMind-AI on GitHub, so you can review or fork the full source.

SkillCorpus is EverMind's open-source pipeline for turning scattered SKILL.md files from public
repositories into reliable agent context. It aggregates sources, applies safety and license gates,
evaluates quality, and matches task-specific skills before the agent answers.
You can use the live SkillHub without cloning this repository. Clone SkillCorpus when you want the open-source machinery behind that experience:
The core code is Apache-2.0 licensed (match/ and evaluate/ are MIT); each skill retains its
upstream license. The public 1,000-skill demo, three agent benchmarks, and live SkillHub show the
result.

skill_search on demand.At answer time, the practical difference is a retrieval layer: SkillHub selects vetted procedural knowledge for the task and puts it into the agent's context.
The result is the same agent with better task-specific procedures available at the moment it needs them — stronger execution without asking users to memorise skill names or wire up tool calls.
Pass rate with no skills → with SkillCorpus, same harness, same backbone (paper, Table 1):
| Harness × backbone | SkillsBench | GDPVal | QwenClawBench |
|---|---|---|---|
| OpenClaw × Qwen3.5-27B | 8.8 → 13.0 | 81.2 → 83.1 | 65.2 → 66.7 |
| OpenClaw × Qwen3.5-397B | 11.1 → 16.9 | 82.2 → 84.0 | 65.7 → 67.0 |
| Raven × Qwen3.5-27B | 10.0 → 16.5 | 82.6 → 83.8 | 66.9 → 70.8 |
| Raven × Qwen3.5-397B | 9.2 → 22.6 | 84.0 → 85.2 | 68.8 → 73.2 |
| Pooled ∆ | +7.5±2.3 (z=3.2) | +1.51±0.49 (z=3.1) | +2.79±0.70 (z=4.0) |
The gain is largest where the task needs procedural knowledge the model does not already have (SkillsBench), and smallest on open-ended economic tasks it can already do (GDPVal).
SkillHub brings skill retrieval to the five agent platforms below. Choose a platform to open its plugin guide:
Two modes, one setting. On demand — the default — gives the agent a skill_search tool and
lets it decide: a long task pays for retrieval at the step that needs it and nothing on the turns
that do not. mode: auto is the older behaviour: search every turn, before the model answers,
with no tool call and no skill names to memorise. They are exclusive; running both would search
twice for one turn.
OpenClaw ships as two packages, because 2.0 dropped the hook the 1.x plugin injects through:
plugin-openclaw for releases up to 2026.7.x, plugin-openclaw2 for 2.0 (2026.8.1) and newer.
The packaged Raven plugin installs and its on-demand mode works today; mode: auto there will
claim the skills stage once Raven merges its upstream context_segments slot, and is inert
until then. Raven's built-in retrieval keeps working either way.
Install SkillCorpus Plugins following https://github.com/EverMind-AI/SkillCorpus/blob/main/skillcorpus_plugin/INSTALL.agent.md
Paste that line to your agent and it installs itself. Per-host setup, the five settings you
will actually touch, what each turn costs and what leaves your machine —
