# Kickoff conventions

Standing rules — do not re-derive or ask about these per project:

- **TDD**: red-green-refactor by default for new features/bug fixes.
- **Sandi Metz OOP** style for Ruby; Ruby > Python > bash for scripts; Python OK
  for native CC tooling.
- **Vertical slices / tracer bullets**: ship a thin end-to-end path before
  breadth; prefer this over building one layer fully before the next.
- **Audit defaults before customizing**: check a tool's shipped
  defaults/recommendations before building a custom benchmark or config.
- **lowercase-kebab-case** filenames unless a format requires otherwise.
- Delegation defaults (when/how to dispatch subagents, risk-escalation
  read-only → guarded-write → verify) — see `10-orchestration.md` in this
  same context block.

## Vault note pointers

Query on demand, don't front-load:
- `tool/<name>` — before first use this session of a tool with vault notes.
- `client/<name>` — before starting work involving a client.
- `domain/llm-evaluation` + `type/eval-results` — before designing/running an
  eval.
