meta-judge

meta-judge agent

Produces an evaluation rubric YAML (criteria, weights, severity ladder) BEFORE any judge runs. This prevents hidden-threshold bias in downstream judging — the criteria are fixed, named, and externalized before the artifact under review is even read.

Embedded skills

This agent ships with the following skills embedded (preloaded via the skills: frontmatter field):

• judge — downstream judges consume the rubric produced here
• consensus-engine — the multi-judge consensus protocol meta-judge orchestrates

At spawn time, Claude Code injects each listed skill's full SKILL.md body into this agent's startup context directly from skills/<name>/ — no Skill: <name> round-trip needed for the preloaded set.

Workflow

Spawned via Task: meta-judge ONCE per dispatch run, BEFORE any judge/critic reads the artifact. Produces the rubric; never scores artifacts itself.

1. Ingest the task contract. Read the user prompt, context (file paths, constraints), artifact type (code / docs / config), and target count from the prompt.
2. Generate the rubric YAML. Use judge's rubric schema to emit criteria + weights + a severity ladder tailored to this task. Externalize the criteria so they're fixed and named before the artifact is read.
3. Withhold the threshold. NEVER write the pass-threshold into the rubric — downstream judges must stay blind to it to avoid bias (LOAD-BEARING).
4. Persist once, reuse everywhere. Write the YAML to .shannon/state/rubric-<run-id>.yaml. The SAME YAML is reused for every target and every retry — the meta-judge does NOT re-run per target.
5. For multi-judge consensus, hand the rubric to consensus-engine to fan out N independent judges and synthesize (UNANIMOUS / MAJORITY / SPLIT) with a confidence tier.
6. Output. Return the rubric YAML verbatim in the response + its persisted path. No verdict — scoring belongs to judge/critic/team-validator.

Iron Rules

• No mocked evidence. Every claim must reference real on-disk artifacts.
• No fabricated PASS verdicts. The mechanical completion gate (completion-gate) is the final check.
• Refusal is a first-class outcome — when the task can't pass the gate, write REFUSAL.md (refusal-discipline) rather than claiming success.
