## What it does

The skill checks which sidecar CLIs are available, then recruits a verifier from another model family when one is present. It runs for consequential changes, such as verification infrastructure, destructive operations, or outputs that other skills rely on. Small, routine edits stay within the current session.

External calls and credit use require one-time consent stored in the UAP. Without consent, the skill does not recruit sidecars. Claude retains the final verdict, and findings from a sidecar must be checked against source code before acceptance. Consent does not trigger a check on every change.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add chrono-meta/forge-harness --skill auto-decorrelation -a claude-code
```

2. **Manually: put the files in place**
- File: `~/.claude/skills/auto-decorrelation/SKILL.md` — Copy the whole skill folder; for one project use .claude/skills/auto-decorrelation/

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add chrono-meta/forge-harness --skill auto-decorrelation -a codex
```

2. **Manually: put the files in place**
- File: `.agents/skills/auto-decorrelation/SKILL.md` — For all projects use ~/.agents/skills/

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add chrono-meta/forge-harness --skill auto-decorrelation -a cursor
```

2. **Manually: put the files in place**
- File: `.cursor/skills/auto-decorrelation/SKILL.md` — Cursor also reads .agents/skills/ and .claude/skills/

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install chrono-meta/forge-harness auto-decorrelation
```

2. **Manually: put the files in place**
- File: `.github/skills/auto-decorrelation/SKILL.md`

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add chrono-meta/forge-harness --skill auto-decorrelation -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/chrono-meta/forge-harness --path plugins/fh-meta/skills/auto-decorrelation
```

### Windsurf (Devin Desktop)

**Manually: put the files in place**
- File: `.devin/skills/auto-decorrelation/SKILL.md` — The legacy .windsurf/skills/ path still works

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add chrono-meta/forge-harness --skill auto-decorrelation -a opencode
```

### Claude.ai

**Claude.ai**
- Zip the folder and upload it in Settings → Capabilities → Skills

Where a file is given instead of a command, copy the files from the source to that path: https://github.com/chrono-meta/forge-harness/tree/HEAD/plugins/fh-meta/skills/auto-decorrelation/SKILL.md

## When to use it
- check a consequential change with a different model family
- discover available sidecar CLIs before verification
- keep routine edits within the current session
- validate a sidecar's findings against source code

## Example prompts
- Recruit a verifier from another model family for this change.
- Check this change with the available sidecar CLIs.

description: Recruits cross-family verifier sidecars (codex, agy, local 4090 over Tailscale) for adversarial verification of load-bearing changes, maximizing model-family diversity against the orchestrator. Mechanically discovers the available sidecar panel, recruits at least one cross-family verifier when present, and degrades gracefully when none are. The governor (Claude) keeps the terminal verdict; sidecar findings must be source-grounded before acceptance. Opt-in via one-time consent, stored in the UAP; fires only on load-bearing changes.

# auto-decorrelation — Cross-Family Verifier Recruitment

The lever for catching a model's blind spots is **decorrelation, not repetition** — a model cannot find
its own family's flaws by repeating itself. FH's adversarial verification (Axis-2 challenger) dispatches
in-session at the session tier, **same family** as the governor. When frontier CLIs are installed and a
local GPU box is live, leaving them idle wastes the one thing that actually raises the verification
ceiling. This skill recruits a **cross-family** verifier for load-bearing changes — and degrades
honestly when none is available.

It is a thin recruitment-and-degrade **policy** that REUSES existing machinery: `agent-composer` does the
actual dispatch, `cross-ecosystem-synergy-detection` inventories tools, `token-budget-gate` gates spend,
the headless CLI patterns and the floor-tier canary already exist. Net-new = the discovery + the
family-diversity recruitment + the degrade ladder only. (A **composing policy skill** — it fans out to
several callees, so its token floor is higher than a leaf skill by design; this is composition, not
reinvention, and the chain is return-path-closed — Step 5 gates acceptance on the callee's back-trace.)

## Triggers

- "recruit a cross-family check" · "decorrelate this verification"
- "use the idle sidecars to verify this" · "don't let codex/gemini sit idle on this gate"
- "is opus alone enough to verify this, or should another family look?"
- "auto-decorrelation"

## Step 0 — Consent gate (default OFF)

External-CLI calls and credit spend are never silent. Run only if the operator has consented (one-time,
surfaced at `install-wizard` setup or right after project mapping). Consent is stored in the UAP
(`tracks/_meta/user_adaptation_profile.md` — behavioral pref, not domain content). No UAP / no consent
(incl. ephemeral/cloud sessions) → **do not recruit**; verify in-session same-family and record a
"single-family, below-ceiling" note. Consent wording is honest by requirement: *"멀티-CLI 사이드카로
