# Gaia: A Skill Tree 🌲
**Share your skill. We prove that it works. Then we name it to you.**
Gaia is not a marketplace of skills, or an installer of some sorts. What we do is we verify your skill, check its capability, and reward them to those who AUTHORED them. Not the model, not the AI, but the HUMAN who authored them.

# 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!

### Skills can fuse. Here's how:
Do a `gaia scan` and `gaia fuse` render in your terminal:
```text
mattpocock/grill-me ────────────┐
├──▶ mattpocock/grill-with-docs ◇
mattpocock/ubiquitous-language ─┘
```
Then the whole tree emerges from the fusions. Here's what it looks like.

## Stars
| Stars | Rank | Notes |
|------:|----------------|--------------------------------------------------------|
| 0★ | Starless | |
| 1★ | Awakened | Default star rank once you push |
| 2★ | Named | You get to be on the tree if you reach here |
| 3★ | Evolved | You ranked up!! |
| 4★ | Extra / Unique | Extra (skill packs/suites), Unique (standalone) |
| 5★ | Ultimate | Ultimate / Unique Ultimate |
| 6★ | Apex | Apex / Unique Impossible |
## Evidence
1. **Evidence Type**
| # | Evidence Type | Notes |
|---|---------------|-------|
| 1 | `arxiv` | scientific papers |
| 2 | `repo` / `repo-own` | contains a repo link |
| 3 | `github-stars` | how many github stars you have |
| 4 | `peer-review` | someone reviewed your skill |
| 5 | `social-signal` | youtube, X, or any post |
| 6 | `proxy` | someone used your skill, maybe in another repo and it has a lot of stars |
| 7 | `benchmark-result` | benchmark that showcases your skill |
| 8 | `verifier-attestation` | our own verifiers attest to your skill |
| 9 | `fusion-recipe` | gaia's own fusion structure |
2. **Evidence Grade**
| Evidence Name | Grade |
|---|----------------|
| Platinum | S |
| Gold | A |
| Silver | B |
| Bronze | C |
| Grey | ungraded |
4. **Trust Magnitude**
This is the evidence grade at the Skill level.
> **Detailed Policy:** See [META.md](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/`](docs/trust/ledger/) (deployed at <https://gaiaskilltree.com/trust/ledger/> once the site rebuilds).

## Quickstart
**1. CLI**
<!-- gaia:version-start -->
Current Gaia CLI version: `7.5.6`.
```bash
curl -fsSL https://gaiaskilltree.com/install.sh | sh
```
Python installation alternative:
```bash
pip install gaia-cli
```
<!-- gaia:version-end -->
<details>
<summary>pipx / Windows alternatives</summary>
**pipx:**
```bash
brew install pipx
pipx install gaia-cli
```
**Windows** (PowerShell one-liner installer):
```powershell
iex (irm https://gaiaskilltree.com/install.ps1)
```
Manual Python/pip fallback (Windows):
```powershell
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):
```bash
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.
</details>
**Update**
```bash
gaia update
```
**2. Init / Scan**
```bash
gaia init
```
```bash
gaia scan
```
Your repo will be scanned for existing skills. Everything will be in `.gaia` folder.
**3. Push to this repo!**
```bash
gaia push
```
A GitHub issue opens automatically. Don't worry, we thoroughly review every intake.
**4. MCP Server**
```bash
claude mcp add gaia -- npx --yes --package=@gaia-research/mcp@latest gaia-mcp
```
Connects your AI agent to the public Gaia Skill Tree registry over stdio. The
scoped package has two binaries, so the explicit package selector invokes
`gaia-mcp`; see the [Gaia MCP 0.4.0 release](https://github.com/gaia-research/gaia-mcp/releases/tag/mcp-v0.4.0) for the current
contract.
---
## Interactive TUI
```bash
gaia
```
Will open all sorts of commands in a nice way.
```bash
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

## MCP Server
[`@gaia-research/mcp@0.4.0`](https://github.com/gaia-research/gaia-mcp/releases/tag/mcp-v0.4.0) is the published Gaia MCP prototype.
Public installation examples use `@latest`; it currently resolves to that
release. The scoped package registers two binaries, `gaia-mcp` and
`skill-hell`, so an MCP client must select `gaia-mcp` explicitly.
| Agent | Install |
|-------|---------|
| Claude Code | `claude mcp add gaia -- npx --yes --package=@gaia-research/mcp@latest gaia-mcp` |
| Any MCP client | Command: `npx`; args: `["--yes", "--package=@gaia-research/mcp@latest", "gaia-mcp"]` |
**Current rich Registry/Bond package surface:**
| Tool | Purpose |
|---|---|
| `gaia_search` | Find generic and Named Skills by task and constraints. |
| `gaia_inspect` | Return an evidence-backed skill dossier. |
| `summon` | Materialize a matching Named Skill into an ephemeral session. |
| `gaia_status` | Report version, compatibility, Registry freshness, counts, and tools. |
`summon` is the current tool name, not `gaia_summon`. It never mutates the
Registry, current repository, or persistent user configuration. The current
package is not an implemented or measured D4 thin `search_skills` + `summon`
profile; that profile does not deprecate the four tools above. Hell/Heaven
scoring, routing eligibility, and content-hash admission or verification are
not shipped.
For a direct CLI summon, use the npx-friendly alias:
```bash
npx --yes skill-hell@latest summon "code review" --card
```
Source and releases: <https://github.com/gaia-research/gaia-mcp>. See the
[Gaia MCP Page](https://research.gaiaskilltree.com/mcp) for current
configuration guidance.

## API
The 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/](https://gaiaskilltree.com/api/)
- **OpenAPI 3.1 spec:** [/api/v1/openapi.json](https://gaiaskilltree.com/api/v1/openapi.json)
Quick examples:
```bash
# 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
curl https://gaiaskilltree.com/api/v1/leaderboard.json
```

## Agent Discovery
To help AI agents and automated clients discover and crawl the registry programmatically:
- **registry graph:** [`/graph/gaia.json`](https://gaiaskilltree.com/graph/gaia.json)
- **Named skills:** [`/named/`](https://gaiaskilltree.com/named/)
- **Trust ledger:** [`/trust/ledger/`](https://gaiaskilltree.com/trust/ledger/)
---
## Ecosystem
Companion tools that build on Gaia but run independently:
- **[skill-fuse](https://github.com/gaia-research/skill-fuse)** — a standalone skill that combines two AI agent skills into one fused skill. Powered by Gaia, works without it. Registered in the registry as [`gaia-research/fuse`](https://gaiaskilltree.com/named/).

## Programmatic Management
The registry is programmatically managed. All meta shifts (adding, merging, splitting, adding evidence) must be performed via the [Gaia CLI](src/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.
Full details: [PRIVACY.md](PRIVACY.md) · [gaiaskilltree.com/privacy.html](https://gaiaskilltree.com/privacy.html)
**Topics:** gaia-skill-tree, ai-agent, skill-registry, capability-graph, evidence-backed, agent-skills, attribution, model-context-protocol, open-source-ai, llm-ops, agent-framework
---
## Inspiration
**Be like Rimuru.** The main inspiration for this repository. Basically stole the idea of the "Great Sage" and applied it to agent skills.
