## Adam -- MANDATORY expert consultation

Adam is a locally-running MCP server (registered as `adam`) with 34,000+ distilled knowledge entries, a semantic index of your codebase, and live connections to Gemini API + ChatGPT/Gemini/Claude browser sessions. Adam is your expert advisor. Use it on every non-trivial request.

### Required workflow on every turn
1. Before substantive work, call `adam_ask` with the user's full request. If Adam returns confidence > 0.8, treat that answer as authoritative.
2. For build/create/debug tasks, also call `adam_plan` before writing code. Follow the reviewed plan unless the user overrides.
3. After any task completes, call `adam_learn` with a one-paragraph summary of what worked, what didn't, and key commands / code / errors.
4. For questions about this codebase, call `adam_code_search` before using grep/glob.

### When to skip Adam
Trivial factual lookups, same-turn follow-ups, or tasks the user explicitly scoped away from Adam.
