USE FOR: setting up rules, reviewing existing rules, scaffolding instruction files, or asking which editor format to use. DO NOT USE FOR: authoring skills (SKILL.md), agent definitions (.agent.md), or CI enforcement of rule files. |

Fusion Rules
Gateway for AI coding assistant rule authoring. Detects the target editor and routes to the right agent.
Routing
| Intent | Agent |
|---|
| Set up GitHub Copilot instructions / rules | agents/copilot.agent.md |
| Set up Cursor project rules | agents/cursor.agent.md |
| Set up Claude Code rules / CLAUDE.md | agents/claude-code.agent.md |
| Set up rules for all editors / mixed team | Run all three agents sequentially |
| Review or improve existing rules | Route to the agent matching the file format |
Intent detection
Detect target editor from the request:
- Copilot — "copilot", "copilot-instructions", ".github/instructions", "applyTo"
- Cursor — "cursor", ".cursor/rules", "mdc", "alwaysApply", "globs"
- Claude Code — "claude", "CLAUDE.md", ".claude/rules", "paths"
- All / unknown — "rules", "instructions", "set up AI rules", or no editor specified
Route directly on detected intent. No editor specified → run all three agents.
Loading behavior
Load ONLY the routed agent file. Each agent carries the full workflow and references .system/fusion-rule-author/ assets and templates on demand. Don't preload all agents.
Multi-editor workflow
When targeting multiple editors:
- Run first agent's scan and interview (Steps 1–3) in full
- Pass scan summary + interview answers as context to remaining agents — they skip Steps 1–3 and start at Step 4 (Classify)
- Each agent drafts, reviews, and writes files for its own editor format
- Generate parallel files with equivalent content — no duplication within a single editor
What this skill does NOT do
- Author skills (
SKILL.md) — use fusion-skill-authoring
- Author agent definitions (
.agent.md) — separate concern
- Write CI checks for rule validation — out of scope
- Migrate entire legacy codebases — incremental adoption only
Safety
- No secrets or credentials in rule files
- No overwrites without showing diff and getting approval
- No invented conventions — only document what the developer confirms
- Show drafts before writing any files
