Gaia AI Agent Skill Registry CLI

Gaia: The Evidence-Backed AI Agent Skill Graph 🌲

Stop guessing if your agent works. Prove it.

Gaia is the open-source registry where AI agent capabilities aren't just claimed—they're verified through a public ledger of code-execution runs, license checks, and security audits.

👉 Claim your skill origin: Run curl -fsSL https://gaiaskilltree.com/install.sh | sh and verify your first skill in under 2 minutes.

Get your badges! Some skills already curated.

Generate yours at gaiaskilltree.com/badges/.

Who maintains this?

Right now just me.

Truth is, Gaia will exist even without anyone sending their skills.

I built this because skills should be attributed to the people who proved them. Permanently, not just until the repo goes private.

So that means, its the developers who make skills maintaining this. I have a thorough curation process, and the dev community is evidence on why this works. As long as developers making skills exists, this registry will exist. This is open-source, so feel free to contribute!

How Skills Fuse

Do a gaia scan and gaia fuse render in your terminal:

  mattpocock/grill-me  ────────────┐
                                   ├──▶  mattpocock/grill-with-docs  ◇
  mattpocock/ubiquitous-language  ─┘

Basics fuse into Extras; Extras can fuse into Ultimates. Evidence powers each ascent.

[!TIP] New here? The interactive tutorial at gaiaskilltree.com covers everything visually: skill tiers, the stars axis, The Initiate's Rite, and copy-paste commands.

---

Stars

Gaia uses a tiered star system (0★–6★) to rank agent capabilities.

Symbol	Tier	Levels
○ Basic	Primitive capability	0★ → 4★
◉ Unique	Mastery without fusion	4★ → 6★
◇ Extra	Composite workflow	2★ → 4★
◆ Ultimate	Platform capstone	5★ → 6★

Evidence

1. Evidence Type (provenance: one of 10 canonical types per the G7 Trust Taxonomy RFC

arxiv repo or repo-own github-stars github-stars-own peer-review social-signal proxy-containment benchmark-result verifier-attestation fusion-recipe

2. Evidence Grade S | A | B | C | ungraded

3. Trust Magnitude This is the evidence grade at the Skill level.

Detailed Policy: See META.md for the full evidence methodology, ranking floors, and prestige requirements.

Public Trust Ledger: The Trust Ledger ranks every named skill by computed Trust Magnitude — see docs/trust/ledger/ (deployed at https://gaiaskilltree.com/trust/ledger/ once the site rebuilds).

API

The Gaia registry is available as a static read-only JSON API — no authentication, no rate limits.

• Base URL: https://gaiaskilltree.com/api/v1/
• Docs: gaiaskilltree.com/api/
• OpenAPI 3.1 spec: /api/v1/openapi.json

Quick examples:

# Health check
curl https://gaiaskilltree.com/api/v1/health.json

# All skills (page 1, sorted by Trust Magnitude)
curl https://gaiaskilltree.com/api/v1/skills/index.json

# Single skill detail
curl https://gaiaskilltree.com/api/v1/skills/garrytan/gstack.json

# Trust leaderboard

Quickstart

**1. CLI

Current Gaia CLI version: 6.0.1.

curl -fsSL https://gaiaskilltree.com/install.sh | sh

Python installation alternative:

pip install gaia-cli

pipx / Windows alternatives

pipx:

brew install pipx
pipx install gaia-cli

Windows (PowerShell one-liner installer):

iex (irm https://gaiaskilltree.com/install.ps1)

Manual Python/pip fallback (Windows):

py -m pip install gaia-cli
$env:PATH += ";" + (python -c "import sysconfig; print(sysconfig.get_path('scripts', 'nt_user'))")

Full Install (for devs) (editable install with all extras):

git clone https://github.com/gaia-research/gaia-skill-tree.git
cd gaia-skill-tree
pip install -e ".[embeddings,dev,docs]"

The dev extra installs packaging/test tools such as build and pytest; without it, packaging-specific tests are skipped locally with guidance to install developer extras.

Update

gaia update

2. Init / Scan

gaia init

gaia scan

Your repo will be scanned for existing skills. Everything will be in .gaia folder.

3. Push to this repo!

gaia push

A GitHub issue opens automatically. Don't worry, we thoroughly review every intake.

4. MCP Server

claude mcp add gaia -- npx @gaia-registry/mcp-server

If you wanna be fancy and do all sorts of agentic MCP goodness.

---

Interactive TUI

gaia

Will open all sorts of commands in a nice way.

gaia skills

Navigate skills:

• Fuzzy search by name, description, or intent
• View tree (^T) and run scan (^G) without leaving the TUI
• Install skills with one keystroke
• Keyboard-native: ↑↓ navigate · Enter install · q quit

Gaia is a shared map of agent capabilities.

Common ways to help:

• Review draft skills for clarity, overlap, and evidence quality.
• Turn accepted reviews into concrete PRs (new skill, fusion, or reclassification).

Programmatic Management

The Gaia registry is programmatically managed. All meta shifts (adding, merging, splitting, adding evidence) must be performed via the Gaia CLI. Hand-editing JSON nodes is deprecated to ensure schema integrity and automated timeline logging.

---

Privacy

Gaia does not store personal information.

• Skills are summarised, not stored. gaia scan records capability type, level, and evidence class — never file contents, prompt text, or conversation history.
• Only public repo links. The registry stores your public GitHub username and a public repo URL when you explicitly submit a named skill. Nothing else.
• Generalised by default. Skill descriptions capture capability categories, not personal details about you or your agent's behaviour.
• No telemetry. The CLI and the static website collect zero analytics or usage data.

Inspiration

Be like Rimuru. The main inspiration for this repository. Basically stole the idea of the "Great Sage" and applied it to agent skills.
