Cross-Check v2.1

Install: INLINECODE0

Verify assumptions in your responses. Opt-in — the agent suggests verification, you decide.

Capabilities Used

• - sessions_spawn — For 2-model verification mode (optional). Requires a second configured model. Only used when user explicitly requests "cross-check 2-model".
• HEARTBEAT.md — Reads (never writes) to check if user has enabled auto-suggestions.

Language

Detect from the user's message language. Default: English.

How It Works

Default: Suggest, Don't Auto-Run

When the agent detects a complex response (3+ assumptions), it appends a one-line suggestion:

CODEBLOCK0

The user chooses whether to activate. No silent auto-invocation.

User Activates

Opt-In Auto-Suggestions via HEARTBEAT

If the user adds the following to their HEARTBEAT.md:

CODEBLOCK1

...then the agent will suggest Cross-Check when it detects 3+ assumptions, without the user needing to trigger it first. This is still a suggestion — the user must reply "cross-check" to actually run it.

Three Output Levels

Default — Confidence Note

For responses with 1-2 assumptions, append:
CODEBLOCK2

Lite — 2 Rounds (same model)

Round 1 "The Analyst": Solve fully, extract assumptions.
Round 2 "The Challenger": Solve from scratch, different angles.

Output (max 8 lines):
CODEBLOCK3

Deep — 3 Rounds or 2-Model

Option A: Reinforced (same model, 3 rounds)
Round 3 "The Synthesizer": Both answers visible, finds consensus/divergence/blind spots. Includes pre-mortem.

Option B: Cross-Check (second model)
Uses sessions_spawn to run a verifier sub-agent. Requires a second configured model.

• - Step 1: Primary solves, extracts assumptions
• Step 2: Verifier challenges each assumption from 4 perspectives (Skeptic, Expert, Beneficiary, Contrarian)
• Step 3: Primary integrates challenges

Output (max 15 lines):
CODEBLOCK4

Assumption Tracking

Every round tracks: core assumptions, confidence (High/Medium/Low), unknowns, biases.

Guidelines for Agent

1. 1. Suggest, don't auto-run — show "Cross-Check available" line, let user decide
2. Respect "cross-check off" — disable suggestions for the session
3. Check HEARTBEAT.md — if auto-suggest is enabled, suggest proactively
4. Compact output — max 8 lines lite, 15 deep
5. Never modify files — reads HEARTBEAT.md only
6. 2-model is optional — only mention if user asks or has multiple models
7. Cost awareness — lite = ~2x tokens, deep = ~3x tokens

Privacy and Safety

• - Session-only — nothing persisted
• No personal data written anywhere
• Verifier receives only problem context + assumptions
• No file writes, no web searches unless user requests
• Uses only OpenClaw's configured providers via sessions_spawn

What This Skill Does NOT Do

• - Does NOT auto-run verification without user opt-in
• Does NOT modify any files
• Does NOT replace the primary model
• Does NOT persist anything
• Does NOT send raw user data externally
