# Playbook

## Definition

A playbook is a governed, agent-consumable procedure for connecting a specific AI coding agent to CoreStory-grounded context and working against it. Each playbook is written for machines first: preconditions to check, ordered steps to execute, and validation criteria to confirm the agent is actually using retrieved organizational context rather than model priors.

## Key properties

- Required sections (per infra#266): **Preconditions** (what must be true before starting — endpoint reachable, auth configured, project ingested), **Procedure** (ordered grounding/retrieval steps), and **Validation** (how to confirm grounded context was used).

- Every playbook page carries the same governance metadata as all pages on this site: owner, last-reviewed date, status, canonical URL, and source (registry:[/linking-map.json](/linking-map.json) ).

- Concrete instances:[Claude (Claude Code / Claude Agent SDK)](/playbooks/claude.md),[Cursor](/playbooks/cursor.md),[Devin](/playbooks/devin.md),[CoreStory Agent (via CoreStory MCP)](/playbooks/corestory-agent.md).

- LLM-first style: bullets, steps, and config blocks — not marketing prose.
