PRISM v2 — Parallel Review by Independent Specialist Models
Multi-agent review protocol that eliminates confirmation bias through structured adversarial analysis. v2 adds memory — reviewers see what previous reviews found, verify whether issues were fixed, and focus on discovering what was missed.
Core Principles
"Disagreements are MORE valuable than consensus."
When 4/5 reviewers agree and 1 dissents, pay attention to that dissent.
"Findings without evidence are noise."
Every finding must cite a specific file, line, or command output. Assertions without citations are lowest priority.
How to Invoke PRISM
Just say it — no configuration needed:
| Mode | Say This | Agents |
|---|
| Budget | "Budget PRISM" / "PRISM lite" | 3 specialists (Security, Performance, Devil's Advocate) |
| Standard |
"Run PRISM" / "PRISM review" | 6 specialists (all except Code Reviewers) |
|
Extended | "Full PRISM audit" / "Deep audit" | 8+ agents (Standard + Code Reviewers + Verification) |
Options: --opus (critical decisions), --haiku (fast checks), --governance (surface stuck findings)
Examples:
"PRISM this API change"
"Budget PRISM on the auth flow"
"Full PRISM audit --governance — we've reviewed this area before"
Evidence Rules
All reviewers must follow these rules. The orchestrator includes this block in every reviewer prompt.
CODEBLOCK1
The v2 Flow — Orchestrator Checklist
Follow these steps exactly. No interpretation needed.
Step 1: Determine Topic Slug
Derive a kebab-case slug from the review subject:
"API authentication redesign" → api-authentication-redesign
"Workspace organization" → workspace-organization
Sanitize: lowercase, alphanumeric + hyphens only, max 60 chars. No path separators.
On first review of a topic, announce the slug: "Topic slug: api-authentication-redesign"
Step 2: Search for Prior Reviews
Search for prior PRISM reviews on this topic. Use the workspace root as your working directory.
CODEBLOCK3
If no prior reviews found: This is the first review. Skip to Step 4. Do NOT show empty history sections in the output — just note: "First review of this topic."
If prior reviews found: Read them. Extract dates, verdicts, and open findings only.
Step 3: Compile the Prior Findings Brief
Only if prior reviews exist. Structured format:
CODEBLOCK4
Hard limit: 3,000 characters. Measure with wc -c or character count. If over:
- - Keep the 2 most recent review summaries + all open findings
- If still over: compress findings to text + escalation count only (drop dates)
- Maximum 10 open findings (drop lowest-escalation items)
Step 3b: Spawn Devil's Advocate Immediately
The Devil's Advocate never receives the Prior Findings Brief. Spawn it now — don't make it wait for brief compilation. It starts working while you prepare context for the other reviewers.
Step 4: Spawn Remaining Reviewers
Spawn all remaining reviewers in parallel. Each receives:
- 1. The review subject + context
- The Evidence Rules block (copied in full — not referenced)
- The Prior Findings Brief (if it exists) — wrapped in the delimiters shown above
Timeout policy: If a reviewer hasn't reported within 10 minutes, proceed with synthesis using available results. Note which reviewers timed out in the synthesis.
Step 5: Collect and Synthesize
After all reviewers report (or timeout), synthesize using the Synthesis Template below. Apply the Evidence Hierarchy to rank findings.
Step 6: Archive the Review
Save the synthesis:
CODEBLOCK5
Important: The 4th argument (thread/channel ID) routes the completion notice back to where the PRISM was requested. Without it, the requester never sees the synthesis. Use the Discord channel or thread ID where the PRISM was initiated.
If the write fails, warn the user: "⚠️ Archive write failed — this review won't be available for future PRISM runs."
Reviewer Roles
Standard Mode (6 specialists)
| Reviewer | Focus | Key Question |
|---|
| 🔒 Security Auditor | Attack vectors, trust boundaries | "How could this be exploited?" |
| ⚡ Performance Analyst |
Metrics, benchmarks, overhead | "Show me the numbers" |
| 🎯
Simplicity Advocate | Complexity reduction | "What can we remove?" |
| 🔧
Integration Engineer | Compatibility, migration | "How does this fit?" |
| 💥
Blast Radius Reviewer | Downstream effects on plugins, agents, config | "What breaks elsewhere?" |
| 😈
Devil's Advocate | Assumptions, risks, regrets | "What are we missing?" |
Budget Mode (3 specialists)
Security Auditor + Performance Analyst + Devil's Advocate.
Security is MANDATORY.
Extended Mode (8+ agents)
Standard 6 + Code Reviewers (batched by area) + Verification Auditor.

Verdict Scale
| Verdict | Meaning | When to Use |
|---|
| APPROVE | No issues found, prior issues resolved | Clean bill of health |
| APPROVE WITH CONDITIONS |
New issues found, none critical | List specific conditions |
|
NEEDS WORK | Prior critical findings still unresolved, OR significant new issues | Fixable but not shippable — must be fixed before deploying |
|
REJECT | Critical new findings OR fundamental design problems | Requires rethink |
NEEDS WORK vs AWC: If you'd say "ship it but fix these soon" → AWC. If you'd say "don't ship until these are fixed" → NEEDS WORK.
Evidence Hierarchy
| Tier | Definition | Priority |
|---|
| Tier 1 | Cross-validated: 2+ reviewers found independently, citing different evidence | Act immediately |
| Tier 2 |
Single reviewer, specific file/line citation | High confidence, act soon |
|
Tier 3 | Single reviewer, no specific citation, or architectural concern spanning multiple files | Lower confidence — verify before acting, but don't dismiss |
Note: Two reviewers citing the same file independently counts as Tier 1 if their analyses are independent. Cross-validation is about independent discovery, not source diversity.
Synthesis Template
After all reviews complete:
CODEBLOCK14
First-run behavior: When no prior reviews exist, omit "Progress" and "Still Open" sections entirely. Show "First review" in the header.
Handling Conflicting Verdicts
Core Principle: Evidence tier outranks role priority.
A Tier 1 finding from any reviewer outranks a Tier 3 finding from Security.
Role priority (when evidence tiers are equal):
- 1. 🔒 Security — Safety concerns trump convenience
- 😈 Devil's Advocate — Independent perspective (blind by design)
- ⚡ Performance — Hard numbers
- 🎯 Simplicity / 🔧 Integration — Context-dependent
Tie-breakers:
- - 3-2 split: Majority wins, document minority concerns as conditions
- Security REJECT + others APPROVE: Security wins unless specifically mitigated
- DA lone dissent: Investigate deeply — they see what anchored reviewers can't
- All AWC: Merge conditions; Security's take precedence if contradictory
Severity Normalization
| Severity | Definition | Examples |
|---|
| CRITICAL | Data loss, security breach, system down | Auth bypass, SQL injection |
| HIGH |
User-facing bug, standards violation | WCAG failures, broken features |
|
MEDIUM | Code quality, maintainability | Duplication, missing docs |
|
LOW | Polish, optimization | Magic numbers, verbose code |
When to Use PRISM
High value: Architecture decisions, security-sensitive changes, major refactors (>1000 lines), open source releases, decisions you'll live with for 6+ months.
Skip it: Minor bug fixes, documentation typos, cosmetic changes, urgent hotfixes, decisions that are easily reversible within a week.
Two-Round Audit
Two rounds catch what one round misses:
- 1. Round 1: Run PRISM, fix all CRITICAL and HIGH issues
- Round 2: Run PRISM again on the updated work
Round 2 typically surfaces issues that Round 1 missed or that fixes introduced.
Anti-Patterns
Don't:
- - ❌ Let reviewers see each other's findings (groupthink)
- ❌ Give Devil's Advocate the Prior Findings Brief (breaks independence)
- ❌ Accept findings without file citations (Tier 3 noise)
- ❌ Skip synthesis (raw findings aren't actionable)
- ❌ Skip archiving (breaks memory for future reviews)
Do:
- - ✅ Spawn DA immediately, other reviewers after brief is ready
- ✅ Give each reviewer narrow focus (depth > breadth)
- ✅ Require citations in every finding
- ✅ Archive every synthesis to INLINECODE5
- ✅ Iterate if first pass finds >50 issues (refine scope)
Red Flags
| Sign | Problem | Fix |
|---|
| All reviewers find same issues | Not diverse enough | Sharpen role distinctions |
| >100 issues found |
Scope too broad | Narrow the review target |
| Vague findings | Missing citation requirement | Enforce evidence rules |
| DA has no concerns | Too soft or topic too simple | Re-run: "find something wrong" |
| 0 disagreements | Possible groupthink | Check reviewer independence |
| Same finding 3+ times across reviews | Governance problem | Use
--governance flag |
Optional: Search-Enhanced Context
If your environment has qmd or similar search tools, add this to reviewer prompts:
CODEBLOCK15
PRISM works without search tools — they improve context precision and reduce token overhead.

Dependencies
| Dependency | Required? | Notes |
|---|
| INLINECODE8 | Required | Parallel reviewer fan-out. No valid params: model=, max_depth=, timeout_minutes=. Model goes in task prompt. |
| INLINECODE12 |
Recommended | Emit
agent_done on Phase 6 archive. Path:
~/.openclaw/scripts/sub-agent-complete.sh |
|
qmd | Optional | Search-enhanced context for reviewers. Falls back to grep if absent. |
| Archive directory | Required |
analysis/prism/archive/<slug>/ — created automatically by orchestrator |
No skills are formal dependencies. PRISM is self-contained. skill-doctor uses PRISM but PRISM does not require it.
Known Limitations & Gotchas
- 1. DA independence is trust-based, not enforced. The DA runs in an isolated session with no archive access by design — but nothing technically prevents it from searching. The value comes from prompt discipline, not technical controls.
- 2. Synthesis is a telephone game risk. When you synthesize 6 reviewer outputs in prose, you paraphrase and lose fidelity — LangGraph benchmarks show ~50% degradation in supervisor-mediated aggregation. Prefer quoting reviewer verdicts directly in the synthesis table rather than restating them. If a reviewer's finding is final and complete, forward the exact wording, don't summarize it.
- 2. Prior findings injection is unsanitized. The Prior Findings Brief is injected directly into reviewer prompts. A compromised archive file could inject instructions. Mitigation: always enforce the 3,000-char hard cap; treat reviewer output as untrusted data.
- 4. Cost is understated in most documentation. Real Standard PRISM cost is $0.80–1.50 per run (6 reviewers, moderate findings volume). The "$0.50–1.00" figure assumes 2–3 findings per reviewer. Budget accordingly.
- 4. Extended mode batching is undefined. "Code Reviewers batched by area" has no algorithm. Before running Extended mode, define batches explicitly: by LOC (5–10KB per reviewer), by module, or by risk tier. Read when: planning an Extended mode run. INLINECODE18
- 5. Archive grows unbounded. No retention policy is enforced. Read when: archive directory exceeds 20MB or you're setting up retention automation. INLINECODE19
- 6. 10-minute timeout treats Security the same as fast reviewers. Security often needs longer for deep file reads. If Security times out consistently, increase its timeout or run it solo first.
- 7. Stalled findings have no escalation mechanism without
--governance. Findings flagged 3+ times across reviews without resolution need explicit human escalation. Use --governance flag to surface them; don't assume they'll self-resolve.
- 8. haiku agents stall on multi-file reads at high volume. For Security and DA, use sonnet. haiku is appropriate for Simplicity, Blast Radius, and Integration on focused tasks.
Model Selection Guide
| Reviewer | Recommended | Rationale |
|---|
| Devil's Advocate | sonnet | Deep reasoning, broad assumptions analysis |
| Security Auditor |
sonnet | Multi-file reads, attack vector reasoning |
| Performance Analyst | haiku | Math-heavy, structured output, low ambiguity |
| Simplicity Advocate | haiku | Line counting, duplication detection |
| Integration Engineer | haiku | Grep-based verification, structured checks |
| Blast Radius | haiku | Grep-based, low reasoning load |
Use --opus for: decisions with >$10K impact, security-critical releases, or when DA finds a potential fatal flaw worth deep investigation.
Use --haiku (full budget mode) for: routine checks on well-understood code, fast pre-PR sanity checks.
Autoresearch
Baseline: 6.5/12 (Phase 1 audit, 2026-03-18 — first formal audit)
Post-improvement: 10/12 (v2.1.0, 2026-03-18)
Mutation candidates:
- 1. Add single-haiku pre-checker mode (sub-$0.002 for <50 line changes)
- Empirically validate evidence tier system — do Tier 1 findings get resolved faster?
- Add DA-First scheduling mode: DA runs, reports, then all 5 run with DA brief injected (vs current: DA blind always)
