# Core Documentation

These files define the structural conventions that govern the agent system itself. They are the grammar rules — boring until you break them, then devastating.

> **Archive note (2026-10-18).** The settings pages (`settings.md`, `settings.json`)
> capture the retired **pi** harness configuration (`frank-default-*` endpoints,
> RTX 3090-era hardware) and are historical records. The live config is
> `agent/config.yml` + `agent/models.yml` in this repo; current fleet endpoints
> are on [System hosts](/system/index.md). The AGENTS.md format pages remain current.

## Concept Files

* [AGENTS.md Format Specification](agents-md-format.md) — Canonical structure and conventions for the system-level instruction file that governs agent behavior.
* [AGENTS.md Index](index-doc.md) — Overview of the cached tool documentation system and how to add new entries.
* [Pi Settings System](settings.md) — pi-era `settings.json` record (archive): providers, models, packages, subagent overrides.
* [dankvoice](dankvoice.md) — Cloned-voice vocalization extension: `/say` and auto-speak over frank-tts, endpoint read from `agent/models.yml`.

## Change Tracking

* [Bundle Change Log](log.md) — Chronological update history.
