# Agent Definition Language — Knowledge Bundle

This is an [Open Knowledge Format](https://github.com/GoogleCloudPlatform/knowledge-catalog/blob/main/okf/SPEC.md)
(OKF v0.1) bundle for the **Agent Definition Language (ADL)** — the open standard for
defining AI agent identity, permissions, lifecycle, compliance, and governance in one
auditable, machine-readable document.

This bundle is a linked structure of directories. The specification, protocol, profiles,
patterns, and examples are each a subdirectory with its own `index.md` listing that
directory's concept files. Those trees are **generated from the pinned specification on
every build** — each page carries the full verbatim source text — so they can never drift
from what the site ships. The top-level concept files (overview, implementations,
standardization, governance) are editorial summaries linking to the authoritative sources on
<https://adl-spec.org>. For the complete text as a single document, fetch
<https://adl-spec.org/llms-full.txt>.

## Contents

* [Overview](overview.md) - what ADL is, who it is for, and the document model.
* [Specification](spec/) - the normative core spec (structure, members, MUST/SHOULD requirements), one page per section.
* [Trust & Runtime Protocol](protocol/) - protocol procedures layered on top of the core spec.
* [Profiles](profiles/) - domain-specific profiles that extend the core spec, one page per profile.
* [Patterns](patterns/) - reusable deployment and design patterns, one page each.
* [Examples](examples/) - worked example ADL documents with full YAML inlined.
* [Implementations](implementations.md) - SDKs, validators, and tooling that consume ADL.
* [Standardization](standardization.md) - ADL's roadmap toward a recognized industry standard.
* [Governance](governance.md) - how the specification is stewarded and evolves.
