name: auto-review-loop description: Autonomous multi-round research review loop. In Copilot CLI it defaults to the native complementary rubber-duck subagent with host-event model evidence; elsewhere it uses Codex, while explicit external reviewer overrides remain available. Implements fixes and re-reviews until a policy-approved positive assessment or max rounds is reached. argument-hint: "[topic-or-scope]" allowed-tools: Bash(*), Read, Grep, Glob, Write, Edit, Skill, Task, mcp__codex__codex, mcp__codex__codex-reply, mcp__manual_review__review, mcp__manual_review__review_reply

Auto Review Loop: Autonomous Research Improvement

🔒 Do not wrap this skill in /loop, /schedule, or CronCreate. It already loops internally (review → fix → re-review) and the reviewer carries round-to-round memory in one threadId (codex-reply). An external timer re-enters from the top each tick — fresh threadId, reviewer memory reset — firing the verdict on wall-clock time instead of on artifact change: zero new signal, full token cost. If you want to schedule something, schedule the external wait that precedes it (experiments done → then run this once). See shared-references/external-cadence.md.

Autonomously iterate: review → implement fixes → re-review, until an independent reviewer gives a policy-approved positive assessment or MAX_ROUNDS is reached.

Context: $ARGUMENTS

Constants

• MAX_ROUNDS = 4
• POSITIVE_THRESHOLD: score >= 6/10 AND verdict ∈ {"ready", "almost"} — both must hold. This matches the operative Phase-E STOP CONDITION exactly; the verdict vocabulary is {"ready", "almost", "not ready"} (a high score with a "not ready" verdict does NOT stop the loop). Earlier wording here used or and a stale verdict set ("accept"/"sufficient"/"ready for submission") — that was an internal inconsistency; the AND form is authoritative.
• REVIEW_DOC: review-stage/AUTO_REVIEW.md (cumulative log) (fall back to ./AUTO_REVIEW.md for legacy projects)
• REVIEWER_MODEL = gpt-6-astra — Default model for the Codex backend. Must be an OpenAI model (e.g., gpt-6-astra, o3, gpt-4o). Manual backend uses a model the user chooses — it must be a recognized model from a different family (OpenAI, Anthropic, Google, DeepSeek, Moonshot/Kimi, Qwen).
• REVIEWER_BACKEND — With no reviewer directive, start as auto; Step -1 runs exactly one two-call native marker/challenge probe for the first review. A bound Copilot CLI root session uses copilot-native (built-in complementary rubber-duck subagent); an unbound/non-Copilot host keeps the existing codex default. Explicit — reviewer: codex, oracle-pro, agy, or manual bypasses the probe and selects that external backend. Explicit — reviewer: copilot retains the compatibility copilot --agent drive mode and its later Codex/manual finalizer. The native path gets both actual model IDs from host session events; it never needs COPILOT_CLI or caller-provided --executor-model. See shared-references/reviewer-routing.md.
• OUTPUT_DIR = review-stage/ — All review-stage outputs go here. Create the directory if it doesn't exist.
• HUMAN_CHECKPOINT = false — When true, pause after each round's review (Phase B) and present the score + weaknesses to the user. Wait for user input before proceeding to Phase C. The user can: approve the suggested fixes, provide custom modification instructions, skip specific fixes, or stop the loop early. When false (default), the loop runs fully autonomously.
• COMPACT = false — When true, (1) read EXPERIMENT_LOG.md and findings.md instead of parsing full logs on session recovery, (2) append key findings to findings.md after each round.
• REVIEWER_DIFFICULTY = medium — Controls how adversarial the reviewer is. Three levels:
  • medium (default): Current behavior — MCP-based review, the executor controls what context the reviewer sees.
  • hard: Adds Reviewer Memory (the reviewer tracks its own suspicions across rounds) + Debate Protocol (the executor can rebut, the reviewer rules).
  • nightmare: Everything in hard + Codex exec reviewer reads the repo directly via codex exec (the executor cannot filter what the reviewer sees) + Adversarial Verification (the reviewer independently checks if code matches claims).
• RENDER_HTML = true — When true (default), auto-render review-stage/AUTO_REVIEW.md to HTML on loop termination via /render-html. Uses --no-review (the loop itself IS the cross-model review; the HTML is a structural conversion). Set false to skip, or pass — render html: false.

⚠️ Nightmare + Manual incompatibility: If REVIEWER_BACKEND = manual and REVIEWER_DIFFICULTY = nightmare, STOP with: "difficulty: nightmare requires Codex CLI / codex exec and is not compatible with --reviewer: manual. Use difficulty: hard, or switch reviewer to codex."

💡 Override: /auto-review-loop "topic" — compact: true, human checkpoint: true, difficulty: hard

Reviewer Calling Convention

When calling the reviewer, branch on REVIEWER_BACKEND:

If no --reviewer: directive was supplied: Set REVIEWER_BACKEND to auto. At Step -1 of the first round, resolve copilot_native_evidence.py using the canonical four-layer helper chain. Generate a fresh binding <run_id>_r<round>_review_<8-random-hex> and invoke marker, wait, then invoke challenge as two distinct root Bash calls. Put the literal binding and concrete resolved helper path in both calls; Copilot Bash calls do not share variables. If the challenge binds, set REVIEWER_BACKEND to copilot-native and use that same challenge for the first review. Do not issue a second activation challenge in Phase A. If it exits 3 because no current Copilot root session is bound, use codex. Explicit reviewer directives bypass this probe. If the helper is missing, native acceptance is unavailable; use Codex only if that external backend is positively available, otherwise emit REVIEW_UNAVAILABLE.

If REVIEWER_BACKEND = copilot-native: Read the challenge nonce and host-reported executor model. Invoke the host's native task tool with agent_type: rubber-duck; do not start a subprocess and do not specify a reviewer model. The prompt contains the exact standalone ARIS_REVIEW_NONCE=<nonce> line, artifact/diff paths, the output contract, and (round 2+) review-stage/REVIEWER_MEMORY.md. It contains no executor summary or fix narrative. After the task completes, invoke copilot_native_evidence.py verify to create the evidence and raw-response artifacts. The verifier must observe one successful linked rubber-duck lifecycle and known, different host-reported model families.

Pass the evidence to both review_gate.py --native-evidence and save_trace.sh --backend copilot-native --native-evidence. A qualifying native positive may stop directly; no external finalizer is needed. A native negative continues with a fresh marker/challenge/subagent next round. Every verdict-bearing native call—including a hard-mode rebuttal ruling—gets one unique <run_id, round, purpose> artifact set and exactly one challenge. Missing, same/unknown-family, malformed, stale, or mismatched evidence is never a verdict. If native complementary dispatch is unavailable, fall back only to a positively available opposite-family backend: Anthropic/Google executor → Codex; OpenAI executor → manual with a reported non-OpenAI model. Otherwise emit REVIEW_UNAVAILABLE. Full protocol: shared-references/reviewer-routing.md.

If REVIEWER_BACKEND = copilot: Require --executor-model: if not provided → emit REVIEW_UNAVAILABLE. Determine executor family from --executor-model (see reviewer-routing.md). Router picks opposite-family profile:

• executor_family=openai → profile="aris-reviewer-claude" (anthropic)
• executor_family=anthropic → profile="aris-reviewer-openai" (openai)
• executor_family=google → profile="aris-reviewer-openai" (openai, default cross)
• executor_family=unknown → REVIEW_UNAVAILABLE (fail closed). Verify the profile file exists at .github/agents/<profile>.agent.md. If missing → REVIEW_UNAVAILABLE. Read its model: field into REVIEWER_MODEL, derive reviewer_family from that model string, and verify it differs from executor_family. Pass the same value through subprocess --model; never trust a caller-supplied family label or profile-only pinning under an Auto session. Identity assurance: --executor-model is caller-declared routing input, not runtime attestation. Record executor_model_source: caller-declared, the derived family_relation, and independence_verified: unverified. A pair of different model strings must never be promoted to independently verified. Capability gate: copilot --help must advertise --model, --effort, and --allow-tool; otherwise emit REVIEW_UNAVAILABLE. Use the copilot --agent subprocess (documented Copilot CLI form) with the selected profile, --model "$REVIEWER_MODEL", --effort xhigh, and --allow-tool=read for each review call. Multi-round: each round is a fresh copilot --agent call with the same profile; reviewer memory is carried via review-stage/REVIEWER_MEMORY.md artifact. If copilot CLI is unavailable → REVIEW_UNAVAILABLE for that drive round; do not silently substitute another transport. A later positive Copilot verdict still requires the separately documented Codex/manual finalizer. See shared-references/reviewer-routing.md for the full copilot contract.

If REVIEWER_BACKEND = codex: Use mcp__codex__codex for new review threads. Use mcp__codex__codex-reply for follow-up rounds (reuse threadId).

If REVIEWER_BACKEND = manual: Use mcp__manual_review__review for new review threads with: prompt: [exact same prompt that would go to Codex] config: {"model_reasoning_effort": "xhigh", "executor_model": "<actual executor model>", "require_reviewer_model": true} Save the returned threadId. Use mcp__manual_review__review_reply for follow-up rounds with: threadId: [saved manual-review threadId] prompt: [follow-up prompt] config: {"model_reasoning_effort": "xhigh", "executor_model": "<actual executor model>", "require_reviewer_model": true} A verdict-bearing manual response MUST begin with Reviewer-Model: <exact-model-id>. Derive reviewer_family from that model identity. Missing, unknown, or same-family identity cannot acquit; for a mandatory escalation, emit REVIEW_UNAVAILABLE rather than guessing.

Prompt fidelity: the manual review task must be exactly the same text that Codex would receive; the transport may add only the required Reviewer-Model: response-format instruction. Review tracing applies to every backend. Native traces are populated from the revalidated host-event artifact rather than caller model declarations.

State Persistence (Compact Recovery)

Long-running loops may hit the context window limit, triggering automatic compaction. To survive this, persist state to review-stage/REVIEW_STATE.json after each round:
