What problem does it solve? Long-running AI-assisted engineering conversations lose context, mix discussion with implementation, and produce duplicated or orphaned notes. This Skill enforces a structured session workflow so every non-trivial conversation is classified, documented, and handed off consistently. ## Core Features & Use Cases - Phase Classification: Routes each conversation round into 1xx (discussion), 2xx (design), 3xx (implementation), 4xx (review), or 5xx (documentation) phases with explicit entry gates. - Session Notes & Handoff: Manages topic folders under .sessions/ with session notes, topic indexes, handoff documents, and archival rules, plus deduplication checks before writing. - Sub-Agent Orchestration: Dispatches sub-agents for code reading and file scanning with a minimal prompt structure, while the main thread acts as orchestrator and verifier. - Use Case: A team running multi-session feature design can rely on the Skill to block premature implementation, require feasibility checks before design, and auto-generate handoff documents when a conversation needs to split. ## Quick Start Start a new non-trivial conversation and ask the assistant to run the session-collab entry classification to determine the current phase, required readings, and next-round plan.
