Force-resync the iTerm2 tab color for a Claude Code session whose hook chain has fallen out of sync. Use when a tab's color is visibly stuck on a stale state (e.g., still orange after the user replied, still white after Claude started processing) — that means Claude Code's automatic PreToolUse/PostToolUse/UserPromptSubmit/etc. events aren't reaching the hook. This skill bypasses the automatic path

Interactive sprint worker. Reads status/ready + owner/ai items from GitHub Issues (or local backlog), presents them with context, groups into proposed PRs, and waits for your approval before building. Dispatches parallel sub-agents with self-review and full testing. Reads CONTEXT.md for domain terminology and .pm/out-of-scope/ for negative constraints. Trigger: "let's build", "work the backlog", "

第五步：为指定课程编写自含教材 lesson.md。调用方式：/write-lesson <book> <module> <lesson>

Manage the macOS notification that fires when a Claude Code tab has been waiting on the user for more than N minutes. Use when the user types /headsup-notifications, asks to enable/disable the "Claude is waiting" notification, wants to change how long it waits before notifying, or wants to test that notifications are working. Accepts on/off, a numeric threshold (minutes), "test" to fire a one-off

Print a health snapshot for the headsup hook stack — daemon PID + heartbeat status, launchd watchdog state, active sessions and their current colors, count of stray PostToolUse events suppressed today, and token usage for the current Claude Code session ($PWD). Use when the user asks "is this still working", "how's the headsup tab thing", "show me the headsup hook status", or invokes /headsup-stat

Process status/needs-triage items through the full pipeline: sort (reject/dedup), spec (brainstorming + writing-plans for M/L/XL items), score against the agent-ready checklist, and promote to status/ready (with owner/ai or owner/human) or reject to out-of-scope. Interactive — you confirm every decision. Trigger: "triage", "process backlog", "review incoming items", "spec items", or /pm:triage.

Find where a feature, component, or concept lives in the ODD codebase. Uses the navigation index for O(1) lookups.

Run the feature-reflector subagent (Layer 4b — top-down product-owner reflection) over one composed feature flow. Produces `lineage/{repo}/feature-reflections/detail/{F-NNN}.yaml` with a stepped-back product-owner narrative + 5-15 falsifiable user-facing hypotheses + per-hypothesis verdicts (confirmed / contradicted / partial / probe-needed) traced through the implementation chain. Contradictions

Convert raw scanner findings into atomic work items in the backlog. Assigns priority, category, effort, and identifies file conflicts.

Customize the three global tab colors for Claude Code's iTerm2 status hook — idle (fresh session), processing (Claude working), and waiting (Claude needs you). Invoke when the user wants to change any of those three colors ("change waiting color to orange", "idle should be gray", "swap blue for purple while processing"). Edits ~/.claude/hooks/headsup-status.conf, applies the matching color to the
