review-cluster

name	review-cluster
description	Use when you need a mid-draft adversarial review of a paper — runs paper-critic + domain-reviewer + claim-verify + blindspot in parallel, then auto-synthesises into a prioritised revision plan. Distinct from /pre-submission-report (final-gate kitchen sink, 13 sub-agents) — this is the active-drafting feedback loop. Triggers: 'review my draft', 'adversarial review', 'cluster review', 'mid-draft critique', 'feedback before pre-submission'.

Review Cluster — Mid-Draft Adversarial Feedback

Parallel fan-out of 4 read-only review agents on an active-drafting paper, with auto-synthesise downstream. Lighter than /pre-submission-report --parallel (4 agents vs 13); designed for tight iteration, not final-gate verification. Outputs reviews/<scope>/review-cluster/YYYY-MM-DD-cluster-report.md (scope = paper slug from the paper path).

Output Path

Per rules/review-artefact-routing.md (auto-loads in research projects (path-scoped to paper-*/ and paper/)):

• Source slug: review-cluster
• Write reports to: reviews/<scope>/review-cluster/YYYY-MM-DD.md (scope = paper slug) inside the project. Path is relative to the research project root, not the Task-Management repo.
• Never at project root (./CRITIC-REPORT.md-style filenames are forbidden — pre-rule layout).
• Idempotency: if today's file exists, append a same-day descriptor ({date}-revision.md, {date}-r2.md, {date}-pre-submission.md) — never overwrite.
• Index update: if reviews/INDEX.md exists, write a one-line entry under "Latest per source" pointing at the new file. Otherwise /review-recap will rebuild the index next time it runs.
• Infrastructure repos (Task-Management, atlas-workspace, etc.): this section does not apply — the path-scoped rule won't load there.

Hard Rules

Existential — block output

1. All 4 sub-agents are read-only. No git, no latexmk, no edits. See subagent-write-guard.md.
2. Auto-synthesise via /synthesise-reviews (unless --no-synthesise). Mid-draft work needs an actionable revision plan, not 4 raw reports.
3. Skip if paper isn't compile-ready — run /latex first; review on broken builds is misleading. The skill checks compile-status before dispatching.
4. Cluster is for the user's own papers. For external papers, use peer-reviewer agent instead.

Format — catch in review

5. Single consolidated report at reviews/<scope>/review-cluster/YYYY-MM-DD-cluster-report.md (scope = paper slug) — not 4 separate files.
6. Findings tiered M/m/n (Major / moderate / minor) per severity-gradient.md.
7. Show which sub-agent flagged each finding (audit trail for traceability).

When to Use

• Active drafting: paper compiles, content is taking shape, want adversarial feedback before final polish
• Mid-revision: addressed first round of supervisor comments; want fresh perspective before next pass
• Pre-pre-submission: ~2 weeks before submission, want to surface major issues with time to address
• Before sharing draft with co-authors

When NOT to Use

• Paper is in final pre-submission state — use /pre-submission-report --parallel (13 sub-agents, full kitchen sink)
• Paper is in early scaffold (introduction only, no method/results) — review will flag everything as missing
• Reviewing someone else's paper — use peer-reviewer agent
• R&R revision response — use /strategic-revision instead (referee-comment-driven)

Modes

Invocation	Behaviour
/review-cluster	Full 4-agent fan-out + auto-synthesise
/review-cluster <paper-path>	Same, explicit paper
/review-cluster --no-synthesise	Run agents in parallel; show 4 raw reports without merging

Architecture

Phase 1 (preflight) → /latex compile check; abort if broken
Phase 2 (dispatch)  → 4 read-only sub-agents in parallel via Task tool
Phase 3 (math)      → IF theory paper: /verify-math on the model section(s) [orchestrator-run skill]
Phase 4 (consolidate) → /synthesise-reviews merges (incl. math verdict) → revision plan
Phase 5 (report)    → reviews/<scope>/review-cluster/YYYY-MM-DD-cluster-report.md

The 4 sub-agents

#	Agent	Why this lens
1	paper-critic (specialist mode if venue known)	General adversarial — structural issues, argument quality, contribution clarity. Most-cited reviewer in the family.
2	domain-reviewer	Math derivations, assumption completeness, citation fidelity at the substantive level, code-theory alignment. Catches what paper-critic doesn't have the lens for.
3	claim-verify	Citation fidelity at the per-claim level — does what's written about Smith (2024) actually match Smith (2024)? Distinct from bib-validate (existence) and paper-critic (structure).
4	blindspot	Peripheral-vision audit — vices in plain sight + virtues being overlooked. Distinct from adversarial review because it surfaces missed opportunities, not just things to fix.

Why these four (and not more):

• referee2-reviewer is excluded — it's the final-stage hostile review, used in /pre-submission-report. Mid-draft, hostile review pre-empts genuine improvement.
• artifact-coherence-auditor / reproducibility-auditor are excluded — relevant only when the paper is paired with a replication artifact, which is typically a pre-submission concern.
• code-paper-auditor is excluded — a separate /code-suite skill exists for code-side review.
• proofread is excluded — editorial issues are too noisy mid-draft; deferred to pre-submission.

Phase 1: Pre-flight

# Auto-detect paper or use arg
PAPER_PATH="${1:-$(ls -d paper-*/paper 2>/dev/null | head -1)}"
[ -z "$PAPER_PATH" ] && echo "No paper-*/ directory found" && exit 1

# Check compile-readiness — exit if last latex run failed
LATEST_PDF=$(find "$PAPER_PATH/out" -name "*.pdf" -newer "$PAPER_PATH/main.tex" 2>/dev/null | head -1)
if [ -z "$LATEST_PDF" ]; then
    echo "Paper not compiled or stale. Run /latex first."
    # AskUserQuestion: run /latex now, or proceed anyway (risky)?
fi

Phase 2: Dispatch

Launch all 4 in a single message with parallel Task tool calls (the standard pattern from system-audit / pre-submission-report). Each gets:

• Read-only with respect to project files under review — Read, Glob, Grep, Bash (read-only commands only) against the paper / code being reviewed; the agent does NOT modify any project source files

• The standard forbid-list from subagent-write-guard.md

• Paper path explicitly named

• Output target — two-step, both required:

  1. Write the per-agent report to reviews/<scope>/<source-slug>/<YYYY-MM-DD-HHMM>.md (scope = paper slug, source-slug = agent name like paper-critic; run mkdir -p reviews/<scope>/<source-slug>/ first) per the agent's own "Log to REVIEW-STATE.md (final step)" instruction. The agent's logging step appends a row to reviews/INDEX.md (or legacy REVIEW-STATE.md) via the shared helper — this is the durable record + stamp that /review-recap reads.
  2. Return a structured findings summary to the orchestrator for the Phase 4 consolidate step.

  These two outputs are NOT mutually exclusive. The file under reviews/<source-slug>/ is the durable artefact and triggers the row stamp; the structured return value is the orchestrator's working copy for consolidation. Earlier wording — "not a file write" — was wrong: it suppressed the per-agent logging step and resulted in 0–1 of 4 cluster dispatches stamping a row in INDEX.md. The 2026-05-17 5-agent patch (commit 23ebcfff) made the agent-side intro unconditional; this dispatch-side fix is the orchestrator-side complement.

Wait for all 4. Do not start Phase 4 (consolidate) until all return.

Phase 3: Math verification (theory papers only)

The 4-agent fan-out covers the conceptual math layer (via domain-reviewer, rung R0) but does not run the computational verification rungs. For a theory paper, add a /verify-math pass so the algebra/analytic claims are machine-checked, not just read.

Detect a theory paper (any of):

grep -lE '\\begin\{(theorem|proposition|lemma|corollary)\}' "$PAPER_PATH"/**/*.tex 2>/dev/null

If there are no formal environments, skip this phase entirely.

If it IS a theory paper, invoke /verify-math (via the Skill tool) scoped to the section(s) holding the model — it decomposes each proposition into atomic obligations and routes them across the spectrum (R0 conceptual · R1 numerical falsification · R2 symbolic/CAS · R3 Lean). /verify-math is a skill, run by this orchestrator in the main session — this is deliberate: the computational rungs (/numerical-check, /symbolic-check, /lean-check) need Bash + sympy/lean, which sub-agents cannot reliably obtain at runtime (the same Bash-grant fragility documented below). The orchestrator always has Bash, so the rungs run here, not inside an agent.

/verify-math writes its own aggregate report to reviews/<scope>/verify-math/<YYYY-MM-DD-HHMM>.md and stamps its own INDEX.md row (it is a self-stamping skill, like /proofread). Fold its aggregate verdict — and any FALSIFIED obligation — into the Phase 4 synthesis as a high-confidence finding (a machine-falsified claim outranks any single reviewer's concern).

Avoid double-work: domain-reviewer (agent #2) and /verify-math's R0 rung both cover the conceptual layer. When this phase runs, tell domain-reviewer in its dispatch prompt that the algebraic identities and comparative-static signs are being machine-verified separately, so it should focus on the conceptual obligations (assumption completeness, citation fidelity, backward logic) rather than re-deriving algebra — see the domain-reviewer "Math R0 Mode" preset.

Phase 4: Consolidate

If --no-synthesise: stop here, show 4 raw reports.

Otherwise, invoke /synthesise-reviews with the 4 reports as input. Output is a prioritised revision plan with:

• Cross-reviewer agreement (claims raised by ≥2 reviewers — high confidence)
• Single-reviewer claims (medium confidence)
• Blindspot virtues (opportunities, not problems — sometimes the most valuable finding)
• Recommended action queue with priority + estimated effort

Phase 5: Report

Save to reviews/<scope>/review-cluster/YYYY-MM-DD-cluster-report.md (scope = paper slug):

# Review Cluster Report — YYYY-MM-DD

**Paper:** <path>
**Compile status:** <PASS / WARN / FAIL>

REVIEW-STATE.md propagation (orchestrator-side stamping)

This skill is an orchestrator in the REVIEW-STATE.md schema. As of the 2026-05-19 architecture change, the orchestrator (this skill) handles all stamping; sub-agents emit directives but do not call the helper themselves. Each of the 4 sub-agents (paper-critic, domain-reviewer, claim-verify, blindspot) ends its final response with a review-state-stamp fenced block (see skills/_shared/stamp-directive-spec.md).

Required orchestrator behaviour

When constructing the prompts for the 4 parallel sub-agents, include this line in each:

Emit a review-state-stamp directive at the end of your final response per skills/_shared/stamp-directive-spec.md. Set trigger: review-cluster (or omit — this orchestrator overrides). Do not call the stamping helper yourself.

After all 4 sub-agents return

For each sub-agent's return:

1. Write the agent's final response to a temp file (/tmp/review-cluster-<agent>.md).
2. Parse the directive:

   ARGS=$(bash ~/.claude/skills/_shared/parse-stamp-directive.sh /tmp/review-cluster-<agent>.md)
   

   If parse-stamp-directive.sh exits non-zero, log a warning ("Agent X return did not contain a review-state-stamp directive") and continue with the next agent — best-effort.
3. Verify the .md report file exists; reconstruct from return content if missing:

   VERIFY=$(bash ~/.claude/skills/_shared/post-dispatch-verify.sh \
       --return-file /tmp/review-cluster-<agent>.md \
       --project "$PROJECT_ROOT" \
       --agent <agent>)
   # $VERIFY is 'OK <path>' or 'RECONSTRUCTED <path>'.
   # Exit code 10 means reconstruction happened — append a marker to the notes
   # so /review-recap shows this row was a recovery, not a real run.
   

   If VERIFY starts with RECONSTRUCTED, append (report reconstructed by orchestrator — agent skipped Write) to the --notes value before stamping. This guards against the blindspot-class failure mode (agent claims to write but skips the call). See log/2026-05-21-blindspot-write-fix.md.
4. Stamp with the orchestrator's --trigger override (overriding whatever the agent emitted):

   eval bash ~/.claude/skills/_shared/review-state-log.sh "$ARGS" \
       --trigger review-cluster \
       --source agent \
       --project "$PROJECT_ROOT"
   

5. Clean up the temp file.

All 4 stamps land in <project>/reviews/INDEX.md with the same orchestrator name and roughly the same Last Run timestamp, making the cluster visible at a glance.

Why the orchestrator stamps (not the sub-agent)

Agents have inconsistent Bash tool grants at runtime (the 2026-05-19 harness investigation showed paper-critic and domain-reviewer self-report Bash unavailable despite YAML grants). The orchestrator always has Bash and always runs after the agents return. Moving stamping here decouples it from agent tool-surface uncertainty.

Schema: ~/Task-Management/docs/reference/review-state-schema.md. Stamp directive format: ~/Task-Management/skills/_shared/stamp-directive-spec.md.

Anti-Patterns

• Don't include referee2-reviewer in the cluster — that's the final-stage hostile review, not mid-draft.
• Don't run cluster review on a broken build — phase-1 check should abort.
• Don't auto-apply fixes from the synthesised report — the report is read-only output. User reviews and dispatches edit-agents (per subagent-write-guard.md) separately.
• Don't run cluster review on every save — designed for milestone-driven iteration, not continuous integration.
