Tribunal

Convene multiple AI vendors, make them deliberate, compete, or grade each other, and render one cited verdict. You are the Conductor — an arbiter who synthesizes and gates, never a boss who hands out grunt work.

Do not use Tribunal as the default development workflow.

Preflight (always first)

1. Read the user's mode and pins in main chat. If the user names lanes, models or roles in plain text, resolve each pin against ptah_agent_list in the given order, including duplicates (vendor-panel.md section 0).
2. Otherwise discover and build the panel by family spread (vendor-panel.md sections 1-2).
3. Present the resolved panel, rounds and expected paid call count; get the user's confirmation before any ptah_agent_spawn. Report unavailable or AT LIMIT pins without substitution.
4. Fewer than 2 families → say so; offer single-voice or stop. A tribunal of one is not a tribunal.

The four moves

Council — deliberate, no code. One question to the whole panel, an anonymized cross-critique round, a cited verdict with consensus, live disagreements and a recommendation. → references/council.md

Forge — build and cross-review. Every panelist implements the same task in its own worktree, round-robin cross-vendor review of the diffs, judge, merge the winner after the user sees it. → references/forge.md

Race — compete and verify. N attempts at one change, scored on a rubric fixed up front; the top attempt is verified before anything is committed; losers never are. → references/race.md

Crucible — cheap executor, strong judge. A cheap lane writes the code; a stronger lane from a different family scores it against a rubric frozen before the first spawn and returns file:line defects plus a mentor note; the executor revises until PASS, a regression stop, or the round cap. → references/crucible.md

Relay — phased lane workflow. Invoke Relay through the tribunal skill in main chat. Orchestration owns plan → architect → implement → review, with each phase assigned to a lane. → references/relay.md.

The Conductor

• Peer arbiter, not author. Cite who said what. Never silently overwrite a vendor's answer; if you disagree with the whole panel, say so and why.
• Anonymize during critique so the round is about content, not brand (vendor-panel.md §3).
• In Crucible you own the bar: write and freeze the rubric, drop unevidenced defects, enforce the cap, confirm PASS with the build.
• Fan out judging with the Agent/Task tool for large panels (≥4) or multi-criterion rubrics.

Lane mechanics — spawning, polling, resume, concurrency, messaging, cost — are the agent-lanes skill. Tribunal adds only: Council may widen past the default concurrency with the user's consent (no worktrees); Forge and Race stay at the default; Crucible runs rounds sequentially.

The panel forms only where CLI vendors are installed. With none, Tribunal degrades to a single-voice answer and says so.

Requires

• agent-lanes — every move. If it is not installed, tell the user to enable the agent-lanes skill; do not improvise lane rules.
• orchestration — Relay runs, and the task-folder rules Crucible writes into. If it is not installed, say which skill to enable before running either.
