MissionBrief

Mandatory input contract for warden dispatch.

When to invoke

• Before any Agent call targeting a warden agent (kernel-warden, future wardens).
• Optional for vanilla cavecrew agents during pilot, but encouraged.

Schema

Prepend this YAML block (inside a fenced code block, language yaml) at the very top of the Agent prompt:

mission-brief:
  end-state: <one sentence, measurable. e.g., "Loop-detector streak counter resets on ACTION steps only; existing 2458 tests still pass.">
  why: <one sentence, the constraint or motivation. e.g., "Observations resetting the streak masked IC-1 loop bug; project memory entry feedback_clean_types.md.">
  key-tasks: <ordered list, ≤5 items>
  authority-bounds:
    paths: <glob list of paths the warden may Read/Edit>
    commands: <list of bash commands the warden may run>
    out-of-scope: <explicit list — refuse rather than escalate silently>
  success-criteria: <deterministic gates: tests-green | file:line landmark | LOC delta ceiling | ablation-warden lift threshold>
  retries-allowed: <integer, default 2>

Validation rule

Refuse to dispatch if any required field (end-state, why, authority-bounds.paths, success-criteria) is missing or contains "TBD" / "TODO" / vague phrasing.

Example

mission-brief:
  end-state: "loop-detector.ts:102 streak counter resets only on ACTION steps; 2458 tests green."
  why: "IC-1 (Apr 12) regression — observations were resetting streak, masking infinite loops."
  key-tasks:
    - Read loop-detector.ts to locate streak-reset call sites
    - Write failing test asserting streak persists across observation
    - Implement guard
    - Run typecheck + targeted test
    - Run full reasoning package suite
  authority-bounds:
    paths:
      - packages/reasoning/src/kernel/capabilities/reflect/loop-detector.ts
      - packages/reasoning/src/kernel/capabilities/reflect/*.test.ts
    commands:
      - bunx turbo run typecheck --filter=@reactive-agents/reasoning
      - bun test packages/reasoning/src/kernel/capabilities/reflect/
    out-of-scope:
      - Edits outside packages/reasoning/src/kernel/
      - Changes to act.ts or terminate.ts
  success-criteria: "Targeted test fails before, passes after; full reasoning suite green; no LOC delta > 30."
  retries-allowed: 2

Status

Ratified as permanent. See [[2026-09-03-warden-pilot-ratified]].
