Fusion Rules

Name: fusion-rules
Author: equinor

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
