> Vendor knowledge for ETYB (the [virtual AI engineering team at etyb.ai](https://etyb.ai)) — currency-stamped per-product and per-role pages across 13 vendor Stacks. Consumed by the `/etyb` skill (and any third-party agent) at runtime; readable by humans too.

## What this site is

- **Vendor knowledge repository.** ETYB itself ships *who* and *how* (the team, decision frameworks, principles — time-invariant) at [github.com/e-t-y-b/etyb-skills](https://github.com/e-t-y-b/etyb-skills). docs.etyb.ai ships *what*: 525 Markdown pages of platform-specific knowledge each team member needs when their work touches a vendor's surface.
- **Currency-stamped.** Every page carries `last_verified_on` and `drift_risk` in YAML frontmatter. Stale pages get a refresh PR; the [knowledge-currency model](/conventions/knowledge-currency/) explains the SLA.
- **Open contract.** Anyone can build agents against this site. The fetch + interpret rules live at [/introduction/for-agents](/introduction/for-agents/).

## How to consume (for agents)

Two entry points at the root:

- **`/llms.txt`** — this file. Compact, human-curated index pointing at the deeper indexes and the canonical pages.
- **`/llms-small.txt`** — auto-generated abridged Markdown of every page. Use as a sitemap with the page titles + descriptions for ~17K lines.
- **`/llms-full.txt`** — auto-generated full text of every page concatenated (~80K lines). Use only when you need everything in context.

Most agents should fetch `/llms.txt`, identify the Stack and product they need, then WebFetch the specific page directly:

- Per-product canonical: `https://docs.etyb.ai/stacks/<vendor>/<product>/`
- Per-role composed view: `https://docs.etyb.ai/stacks/<vendor>/<role>/`
- Stack index: `https://docs.etyb.ai/stacks/<vendor>/`

Pick the most-specific URL that exists; fall back to broader on 404.

## Conventions and protocols

- [Knowledge Currency Model](/conventions/knowledge-currency/) — per-product `drift_risk`, `last_verified_on` SLAs, soft / strict path
- [How to Read These Docs (Agents)](/introduction/for-agents/) — the fetch + interpret contract
- [Contributing](/conventions/contributing/) — currency refresh PRs, new product pages, new Stacks

## Vendor-skill delegation

Some vendors ship their own MCP servers or agent skills. When those are installed in the user's environment, ETYB defers to them rather than fetching from this site — the vendor's own surface knows current state better. Stack `delegate_to_skills` blocks declare which delegates each Stack prefers; the slim local pointer in [`e-t-y-b/etyb-skills`](https://github.com/e-t-y-b/etyb-skills) is the source of truth for that mapping.
