guider

Establishes and enforces engineering conventions, quality gates, and architectural guardrails for a codebase, and onboards itself via `/guider init`. Use whenever the user wants to set up or apply project standards: conventions, naming, linters, formatters, pre-commit hooks, secret scanning, CI gates, data integrity (RLS, encryption, transactions, idempotency, race conditions), enums over string literals, bounded contexts and state machines, folder structure, fast/full test split, responsibility separation, DRY, and API docs (OpenAPI/Swagger generated from code and drift-gated). Also trigger on "set conventions", "harden this repo", "audit against standards", "apply the audit fixes", "document the API"; on `/guider init`, `/guider audit`, `/guider fix`, or `/guider spec`; on requests to generate an AGENTS.md / CLAUDE.md / ARCHITECTURE.md / APPLICATION.md; or when asked to follow the project's established standards while writing code.
