## What it does

The skill evaluates multi-component setups by reading `~/.claude/plugins/installed_plugins.json` and comparing it to `enabledPlugins` in `~/.claude/settings.json`. It maps existing assets for each plugin, categorizing skills, agents, commands, hooks, and MCP configs while keeping track of absent asset types.

Next, it determines call pathways between compatible items, such as `{component}:{skill}` or `{component}:{agent}` subagent invocations. If multiple tracks exist, it executes `bash scripts/mapped_tracks.sh` to identify governance mechanisms that can be transplanted between projects.

In environments with only one installed component, the skill skips execution because there are no pairings to evaluate. Simple evaluations run on Sonnet. The system escalates to Opus when analyzing cross-project setups or handling cold starts.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add chrono-meta/forge-harness --skill cross-ecosystem-synergy-detection -a claude-code
```

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

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add chrono-meta/forge-harness --skill cross-ecosystem-synergy-detection -a codex
```

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

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add chrono-meta/forge-harness --skill cross-ecosystem-synergy-detection -a cursor
```

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

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install chrono-meta/forge-harness cross-ecosystem-synergy-detection
```

2. **Manually: put the files in place**
- File: `.github/skills/cross-ecosystem-synergy-detection/SKILL.md`

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add chrono-meta/forge-harness --skill cross-ecosystem-synergy-detection -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/chrono-meta/forge-harness --path plugins/fh-meta/skills/cross-ecosystem-synergy-detection
```

### Windsurf (Devin Desktop)

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

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add chrono-meta/forge-harness --skill cross-ecosystem-synergy-detection -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/cross-ecosystem-synergy-detection/SKILL.md

## When to use it
- uncover cross-invocation pairs across active plugins and skills
- detect configuration drift between installed and enabled components
- rank potential tool synergies in a structured table
- transplant governance patterns across project harnesses

## Example prompts
- Do my installed tools work well together or are they isolated?
- Find synergies between my plugins and show the ranking table
- I just installed a new component, check for conflicts and combinations

# cross-ecosystem-synergy-detection — Multi-Ecosystem Automatic Synergy Discovery

Automatically discovers cross-invocable pairs in environments with multiple installed plugins and cross-CLI tools, and derives a synergy ranking table.

## Activation Triggers

1. **Multi-ecosystem component environment specified**: "multiple plugins/cross-CLI installed", "synergy with other components", "cross-ecosystem", "run together"
2. **New component added/removed**: "component install", "add/remove component"
3. **Synergy check phrasing**: "are they working in isolation?", "can they be integrated?", "environment check", "combination effect"
4. **Registry change detected** (optional): If a user-maintained `LOCAL_SKILL_REGISTRY.md` is present, Step 7 runs when a new project/skill is registered. The registry is not auto-created — absent file → Step 7 reports `[NOT-CONFIGURED]` and skips its body (see Step 7-1 outcome table).

**Exception**: Single-component environments (1 or fewer installed → no meaningful activation)

### Natural Language Triggers (General user phrasing — activates without internal vocabulary)

| Example phrasing | Intent |
|---|---|
| "Do my installed tools work well together?" | Check synergy of installed plugins/skills |
| "Would using this and that together be better?" | Explore cross-invocation possibilities |
| "I have multiple plugins installed in Claude — am I using them well?" | Diagnose installation ecosystem utilization |
| "My tools seem to be working in isolation" | Detect namespace/cwd fragmentation |
| "I just installed something new — check for conflicts with existing setup" | Check after adding new component |
| "I have multiple installs but not sure if I'm using them right" | Diagnose installation ecosystem utilization |
| "Wouldn't this and that work better together?" | Explore cross-invocation possibilities |
```
