Devil's Advocate Skill
Challenge research assumptions and identify weaknesses in your arguments.
Purpose
Based on Scott Cunningham's Part 3: "Creating Devil's Advocate Agents for Tough Problems" - addressing the "LLM thing of over-confidence in diagnosing a problem."
For formal code audits with replication scripts and referee reports, use the Referee 2 agent instead (.claude/agents/referee2-reviewer.md). This skill is for quick adversarial feedback on arguments, not systematic audits.
When to Use
- Before submitting a paper
- When stuck on a research problem
- When you want to stress-test an argument
- During paper revision planning
When NOT to Use
- Code audits — use the Referee 2 agent instead
- Replication verification — use the Referee 2 agent instead
- Quick proofreading — just ask for a read-through
- When you want validation — this skill is designed to challenge, not affirm
Workflow
- Understand the claim — Read the paper/argument being evaluated
- Generate competing hypotheses — If evaluating a research question or design, load
references/competing-hypotheses.md and generate 3-5 rival explanations before critiquing
- Run the debate — Use the multi-turn debate protocol below (default) or single-shot mode for quick checks
- Deliver the verdict — Synthesize surviving critiques with severity ratings
Multi-Turn Debate Protocol (Default)
Inspired by the simulated scientific debates in Google's AI Co-Scientist. A one-shot critique is easy for an LLM to produce but often superficial. Multi-turn debates force each critique to survive a defense, filtering out weak objections and sharpening the strong ones.
Round 1: Adversarial Critic
Adopt the persona of a hostile but competent reviewer. Challenge on:
- Theoretical foundations — Are the assumptions justified?
- Methodology — Limitations? Alternative approaches?
- Data — Selection bias? Measurement issues? External validity?
- Causal claims — Alternative explanations? Confounders?
- Contribution — Novel enough? Does it matter?
Produce numbered critiques (aim for 5-8), each with a concrete statement of the problem.
Round 2: Defense
Switch persona to the paper's author. For each numbered critique, provide the strongest possible defense:
- Cite evidence from the paper that addresses the concern
- Explain design choices that mitigate the issue
- Acknowledge limitations honestly where the defense is weak
- Propose concrete fixes where the critique has merit
Round 3: Adjudication
Switch to an impartial senior reviewer. For each critique-defense pair, rule:
- Critique stands — the defense is insufficient; this is a real weakness
- Critique partially addressed — defense has merit but issue remains
- Critique resolved — the defense adequately addresses the concern
Final Synthesis
Produce a structured report with only the surviving critiques (stands + partially addressed), ranked by severity:
## Devil's Advocate Report
### Critical (must fix before submission)
1. [Critique] — [Why the defense failed] — [Suggested fix]
### Major (reviewers will likely raise)
2. [Critique] — [What remains after defense] — [Suggested fix]
### Minor (worth acknowledging)
3. [Critique] — [Residual concern] — [How to preempt]
### Dismissed
- [Critiques that were resolved in Round 2, listed briefly for transparency]
Output Path & Stamping
When run on a paper in a research project (a paper-*/ directory exists), persist the report and stamp it into the review log — the same wiring as proofread and bib-validate, so review-recap renders it as a first-class review (not a manual slot).
- Write the report to
reviews/<scope>/devils-advocate/<YYYY-MM-DD-HHMM>.md, where <scope> is the in-scope paper slug (e.g. paper-prima) or _project for a project-level argument. Create the dir first (mkdir -p reviews/<scope>/devils-advocate/). Never overwrite — each run is timestamped to the minute. Per rules/review-artefact-routing.md, never write to the project root.
- Stamp
reviews/INDEX.md:
bash <skills-root>/_shared/review-state-log.sh \
--check devils-advocate \
--paper "<scope>" \
--verdict "<PASS|ISSUES FOUND>" \
--open-issues "<surviving-critiques>/<total-critiques-raised>" \
--report "reviews/<scope>/devils-advocate/<YYYY-MM-DD-HHMM>.md" \
--notes "<one line: e.g. '2 Critical, 1 Major survive; identification strategy weakest'>" \
[--trigger "review-cluster|pre-submission-report"]
- Verdict:
PASS if no critiques survive adjudication (all dismissed); ISSUES FOUND otherwise.
- Open issues: surviving critiques (Critical+Major+Minor) over total raised in Round 1.
- Trigger: pass an orchestrator name only if invoked via
review-cluster or pre-submission-report; otherwise omit.
Skip stamping only for non-paper use (challenging a bare argument with no project context) or single-shot mode on a paragraph — then the report stays inline. Schema: the installed shared resource shared/review-state-schema.md.
Single-Shot Mode
For quick checks (e.g., "just poke holes in this argument"), skip the multi-turn protocol and produce a direct critique. Use when the user says "quick", "just challenge this", or the input is a paragraph rather than a full paper.
Example Use
"Play devil's advocate on my research paper about preference drift - specifically challenge my identification strategy and the assumptions about utility functions."
Council Mode (Optional)
For the highest-stakes arguments, run the debate across multiple LLM providers — different models have genuinely different reasoning patterns, producing adversarial tension a single model cannot replicate. Each model plays Adversarial Critic, cross-reviews the others, and a chairman ranks surviving critiques by cross-model agreement. Trigger: "council devil's advocate" / "thorough challenge". Full orchestration + invocation: ../shared/council-protocol.md.
Value: High — the multi-turn debate becomes genuinely adversarial when different models play different roles. A critique that survives cross-model scrutiny is almost certainly a real weakness.
