Use when the user wants an HTML discussion artifact — a page generated and revised over the life of a conversation. Best for planning a feature, comparing options, surfacing decisions with options grids, recapping analysis, dogfooding a design. Pages save to .scratch/<slug>.html with a sibling .scratch/<slug>.json manifest as source of truth. Sections are byte-addressable by ID via shell scripts in bin/, so revisions cost ~10 tokens each instead of re-reading a 30KB file. Not a build system; not a replacement for visual-explainer.

Simulates pair programming with a third-party auditor for autonomous execution of work. Point it at a task, a list of tasks, or a plan with scoped scenarios — the lead decomposes as needed and dispatches a per-scenario trio (ping = navigator, pong = driver, auditor = QC). Use when prior attempts produced premature-done or wrong-diagnosis loops, or when the user invokes /ping-pong.

Use when the user asks what a project `.scratch/` folder is for, wants a safe place for temporary scripts/artifacts, or needs guidance on promoting ad-hoc work into committed project code.

Claude Code dev-session analytics for THIS repo — DuckDB views over the native session JSONL logs at `~/.claude/projects/<project>/*.jsonl`. Tracks token spend, tool calls, skill activations, sessions, cache efficiency. Use when answering "how much did today cost?", "what tools am I using most?", "show me my last 5 sessions", "which sessions burned the most tokens?".

Run, extract, update, or check the status of the FlowStay feature catalog at `features/`. Use when the user invokes `/features`, asks to extract features from the architecture doc, asks to run the feature catalog against the codebase, asks to re-sync the catalog after a doc edit, or asks about catalog coverage status.
