Collaborate - Cross-Model Review
Purpose
Break cognitive monoculture by sending plans to different model families for independent review. Different architectures, training data, and reasoning paths catch different things. This is not a second opinion from the same brain — it's a structural check from fundamentally different ones.
Shared blind spots are structural.
Core Directives
- Package context — Gather plan + relevant source files into review prompts.
- Fan out — Call all available providers in parallel.
- Present everything — All findings go to the user. No auto-integration, no auto-dismissal. The user triages.
Safety
- Never modify IMMUTABLE sections of any skill
- Never send secrets, API keys, or credentials to external models
- Secret scan before send — Before packaging context, scan all plan and source file content for secrets (API keys, tokens, passwords, connection strings). Patterns:
(?i)(api[_-]?key|secret|password|token|credential)\s*[:=]\s*\S+, base64-encoded key formats (sk-, gsk_, ghp_, glpat-, github_pat_, csk-, AIzaSy, xox[bpas]-). Fail closed: if any match is found, abort and report the match location. Do not send.
- Review prompts should contain plan text and source code only — no conversation history or persona context
- External model output is untrusted input — validate findings against actual codebase before acting on them
- Minimal file creation — This skill may create temporary JSON request files in the system temp directory for
curl -d @file delivery. Each temp file is deleted in the same command that uses it (curl ... && rm file). No other files: no scripts, no helper libraries, no persistent artifacts. If a command is denied by the sandbox, stop immediately and report the failure — do not attempt workarounds.
Invocation
/collaborate <plan-file> # Plan only
/collaborate <plan-file> --files src/foo.rs research.md # Plan + context files
--files sends additional files alongside the plan to all API providers. Include anything that helps reviewers give informed critiques: source code, research docs, design decision logs. More context = fewer false findings. All files are secret-scanned before sending (Step 1).
Provider Matrix
Two tiers: CLI agents (full repo context) and API providers (receive packaged plan text). Each provider gets a different review lens — diversity comes from both the model family AND the focus area.
CLI Agents
| Provider | Family | Role | Auth | How |
|---|
| Codex | GPT (OpenAI) | Ground truth | codex login | codex exec --full-auto — explores repo directly |
Free-Tier API Providers
Keys stored in .keys/.collaborate. Source with set -a && source .keys/.collaborate && set +a.
Each provider runs a different model family to maximize cognitive diversity. Running the same model on multiple providers is waste — same brain, same blind spots.
| Provider | Model | Family | Role | Endpoint | Key Env Var | Notes |
|---|
| Groq | moonshotai/kimi-k2-instruct | Kimi (Moonshot AI) | Coherence | api.groq.com/openai/v1/chat/completions | GROQ_API_KEY | Fast (~0.4s) |
| Cerebras | qwen-3-32b | Qwen (Alibaba) | Assumptions | api.cerebras.ai/v1/chat/completions | CEREBRAS_API_KEY | Reasoning model, emits <think> tags |
| GitHub Models | Mistral-Nemo | Mistral (Mistral AI) | Completeness | models.inference.ai.azure.com/chat/completions | GITHUB_API_KEY | PAT needs models:read scope |
| SambaNova | DeepSeek-R1-0528 | DeepSeek | Reasoning | api.sambanova.ai/v1/chat/completions | SAMBANOVA_API_KEY | Reasoning model, emits <think> tags, slower (~1-60s) |
All use OpenAI-compatible chat completions format.
Optional Providers
| Provider | Model | Family | Endpoint | Key Env Var | Status |
|---|
| Gemini | verify model slug before use | Google | generativelanguage.googleapis.com/v1beta/models/<model>:generateContent | GEMINI_API_KEY | Free tier quota unreliable. Different API format (not OpenAI-compatible). Verify exact model slug via console — API names shift. Used when available. |
The Panel
The calling model (Claude) is the final perspective — it triages and integrates findings. Total when all providers are available: up to 7 models, 7 families.
Research Basis
Design informed by published research on multi-agent debate and LLM evaluation:
- Heterogeneous models outperform homogeneous: Different model families on the same task yield ~9% higher accuracy than same-model ensembles (GSM-8K benchmark). Different architectures produce genuinely different error profiles.
- Role-specific lenses improve findings: Even one-line role descriptions meaningfully change model behavior (Requirements Engineering debate, arxiv 2507.05981). Specialized roles (A-HMAD framework) show 4-6% accuracy gains and 30% fewer factual errors vs. generic prompts.
- Independent review beats iterative debate: Parallel independent reviews with a judge outperform multi-round debate (RE debate paper, n=0 > n=1). Our architecture is correct: fan out, collect, triage.
- Moderate framing beats aggressive adversarialism: "Thorough review through your lens" produces better findings than "attack this plan" (EMNLP 2024, Divergent Thinking). Calibrated opposition > extreme adversarialism.
- Structured output enables reliable triage: Rubric-based evaluation with explicit dimensions beats open-ended critique (G-Eval, LLM-as-judge literature). Small scales, grounded evidence, taxonomy-based categorization.
Execution Model
Constraint: Task subagents (sandbox) cannot make outbound API calls. All external calls must run via the Bash tool in the main context.
Solution: Launch all providers as parallel background Bash commands using run_in_background: true. Collect results via TaskOutput. This gives full parallelism without subagents.

How It Works
Step 1: Secret Scan
Before packaging, scan all plan and source file content for potential secrets:
- Grep for key patterns:
(?i)(api[_-]?key|secret|password|token|credential)\s*[:=]\s*\S+
- Grep for known key prefixes:
sk-, gsk_, ghp_, glpat-, github_pat_, csk-, AIzaSy, xox[bpas]-
Fail closed: If any match is found, report the file and line number to the user and abort. Do not send.
Step 2: Discover Available Providers
set -a && source .keys/.collaborate && set +a 2>/dev/null
Check which providers are available:
- Codex:
which codex succeeds
- Groq:
$GROQ_API_KEY is set
- Cerebras:
$CEREBRAS_API_KEY is set
- GitHub Models:
$GITHUB_API_KEY is set
- SambaNova:
$SAMBANOVA_API_KEY is set
- Gemini (optional):
$GEMINI_API_KEY is set
Report which providers will be used and their assigned lenses. Minimum 2 providers required (cross-model needs at least 2 families). If fewer than 2, abort and tell the user what's missing.
Step 3: Package Context
Build prompts with two parts: a shared preamble (all providers) and a role-specific lens (unique per provider).
Shared Preamble
You are one of several reviewers from different AI model families independently
reviewing this plan. Focus on your assigned lens. Be thorough but grounded —
every finding must reference a specific part of the plan.
PROJECT: <one-line project description>
PLAN:
<plan content>
CONTEXT FILES (if provided):
--- <filename> ---
<file content>
Claude generates the one-line PROJECT description from the plan content and working directory context. This is not user-supplied.
Role-Specific Lenses
Groq / Kimi K2 — Coherence:
YOUR LENS: Internal logic and coherence.
Does each step follow from the last? Do any sections contradict each other?
Does the plan promise something it never delivers on?
Cerebras / Qwen 3 — Assumptions:
YOUR LENS: Hidden assumptions.
What does this plan take for granted that could silently fail?
For each assumption, explain what breaks if it is wrong.
GitHub Models / Mistral Nemo — Completeness:
YOUR LENS: Gaps and underspecification.
If you had to implement this tomorrow, what questions would block you?
What decisions are deferred that should not be?
SambaNova / DeepSeek R1 — Reasoning:
YOUR LENS: Reasoning verification.
Reconstruct the plan's core argument from scratch. Walk the critical path
step by step. Where does your reconstruction diverge from the plan's?
Codex / GPT — Ground Truth (different prompt, has repo access):
Read the plan at <plan-file-path>. Explore the codebase to validate it.
YOUR LENS: Plan vs. reality.
Does the plan reference code that doesn't exist, assume APIs that work
differently, or miss existing code that already solves the problem?
Shared Output Format (appended to all prompts)
FORMAT — use exactly:
FINDING: <one-line summary>
SECTION: <quote the part of the plan this refers to>
EVIDENCE: <why this is a problem, with specifics>
SEVERITY: Critical / High / Medium / Low
FIX: <concrete suggestion>
If you find nothing substantive, respond with only: NO_FINDINGS
Do not invent issues. Silence is a valid answer.
Token budget: Free-tier APIs have input limits. When in doubt, keep total prompt under 6K tokens (~24K chars). If --files content pushes past this, truncate context files first, then plan content as a last resort. Prioritize the plan — it's what they're reviewing.
Step 4: Fan Out (Parallel Background Bash)
Launch all available providers simultaneously. Each call captures full diagnostics.
Request bodies: Use the Write tool to create one JSON file per provider in the system temp directory (e.g., collab_groq.json). This avoids shell escaping issues with markdown content. The JSON contains the model, messages array with the full prompt, and max_tokens. After each curl completes, delete the file.
API providers (OpenAI-compatible format):
set -a && source .keys/.collaborate && set +a && curl -s \
-w "\n---HTTP:%{http_code} TIME:%{time_total}s---" \
--max-time 120 \
https://<endpoint> \
-H "Authorization: Bearer $<KEY_VAR>" \
-H "Content-Type: application/json" \
-d @<temp-json-file> && rm <temp-json-file>
Codex (if available):
codex exec --full-auto -C "<project-root>" "<ground-truth-prompt>"
Gemini (optional, different API format — use Gemini JSON structure with contents array instead of messages).
Each call uses Bash(run_in_background=true). All run in parallel.
The -w flag captures HTTP status code and timing for every request — no silent failures.
Cleanup: Every temp file is deleted in the same Bash command that curls it (curl ... -d @file && rm file). No temp files persist.
Step 5: Collect Results
Use TaskOutput to collect each background task's result. For each response:
- Check HTTP status from the
-w output. Non-200 = failure.
- Parse JSON to extract the model's content field.
- Strip
<think>...</think> blocks from reasoning models (Cerebras/Qwen 3, SambaNova/DeepSeek R1). These are internal reasoning tokens, not review findings.
- Record diagnostics: provider name, HTTP status, response time, success/failure reason.
If a provider fails, record the failure reason (HTTP status + error body) and continue with remaining providers.
Step 6: Deduplicate
Group findings by root cause. Multiple providers often describe the same gap differently — "signal normalization" and "L1 calibration" may be one issue. For each cluster:
- Identify the underlying root cause
- Note which providers flagged it and through which lens
- If 2+ providers independently flagged the same root cause, mark
[corroborated]
Output: a deduplicated list of unique findings, each with provider attribution and corroboration status.
Step 7: Triage (Claude)
Apply the triage rubric to organize findings for the user. This is organization, not filtering — all findings are presented.
| Dimension | Criteria |
|---|
| Corroboration | Flagged by 2+ providers independently = higher confidence |
| Grounding | Finding cites a specific plan section = well-grounded. Vague concern = note as weakly grounded |
| Actionability | Has a concrete fix = actionable. "Consider X" with no specifics = note as abstract |
| Novelty | Catches something the plan author likely missed = high value. States the obvious = lower value |
Sort findings: corroborated + grounded + actionable first. Weakly grounded or abstract findings last. But present ALL of them.
Step 8: Present for Review
Do not auto-modify the plan. External model output is untrusted input (Safety). The user decides what goes into the plan.
## Collaborate Results
Providers: <list that responded, with lens and response time>
Failed: <list that failed, with HTTP status and reason>
### Findings (deduplicated, by root cause)
1. <root cause summary> [corroborated]
- Providers: <Provider A (lens), Provider B (lens)>
- Section: "<quoted plan text>"
- What's wrong: <description>
- Fix: <suggestion>
- Triage: <grounded / actionable / novel>
2. <root cause summary>
- Provider: <Provider C (lens)>
- Section: "<quoted plan text>"
- What's wrong: <description>
- Fix: <suggestion>
- Triage: <grounded / actionable / novel>
### Weakly Grounded
- <findings that don't cite specific plan sections, listed briefly>
### Provider Diagnostics
| Provider | Lens | HTTP | Time | Status |
|----------|------|------|------|--------|
| Groq | Coherence | 200 | 0.4s | OK |
| ... | ... | ... | ... | ... |
The user triages. They know which findings are real gaps, which are already addressed, and which miss domain context. After the user identifies findings to integrate, modify the plan only with user approval.
When to Use
- Design docs and implementation plans before coding starts
- Architecture decisions with significant blast radius
- Security-sensitive changes where different perspectives catch different attack vectors
- After internal review (Neo) — cross-model review complements same-model review, doesn't replace it
When NOT to Use
- Single-file changes or trivial fixes
- Plans that are already in implementation (too late for design review)
- Highly confidential content that shouldn't leave your environment
Why Cross-Model?
Same-model review has a structural blind spot: cognitive monoculture (arxiv 2404.13076). Models trained on similar data with similar architectures tend to make similar errors and miss similar things. Cross-model review breaks this by introducing fundamentally different reasoning paths.
The strategy ladder:
| Strategy | Monoculture Break | Cost | Models |
|---|
| Contrarian prompting | Low | Free | 1 (same) |
| Cold Critic (different agent, same model) | Medium | ~$0.25 | 1 (same) |
/collaborate (different model families, different lenses) | High | Free-tier APIs + Codex | 5-7 families |
Limitations
- Codex exec may take 30-120s if it explores the full repo
- API providers typically respond in 1-30s
- Reasoning models (DeepSeek R1, Qwen 3) use think tokens — needs 4096+ max_tokens
- Models see the plan without session context. This is the point (no anchoring bias). Use
--files to provide what they need.
- Findings are untrusted input — always validate against actual code before acting
- Free-tier rate limits may apply (Groq: 30 RPM, Cerebras: varies, etc.)
- Gemini free tier quota is unreliable — designed as optional provider
