# 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.
* [Pi Settings System](settings.md) — pi-era `settings.json` record (archive): providers, models, packages, subagent overrides.
* [dankvoice](dankvoice.md) — Voice output is the `dank/dankvoice` package (`pi install git:`); this page keeps fleet wiring and the cutover procedure.
* [OMP Status Line Customization](statusline.md) — How presets, composer shapes, and segment arrays actually interact; the fleet's tuned bar. (moved from /pi/, 2026-10-19)
* [OMP Subagent Limits & Fan-out Policy](subagent-limits.md) — Live caps: concurrency 2, no nested spawns (the `maxRecursionDepth: 0` trap), per-endpoint in-flight ceilings, isolation policy. (moved from /pi/, 2026-10-19)
