back-on-the-horse
Recap what happened on a project in roughly the last 24 hours (or a stated window), rendered as a visual card with a light "rough morning, here's the highlights" tone, plus a clear list of what's still open and what to do next. Triggers on "what happened while I was out", "catch me up", "back on the horse", "recap the last 24 hours", "get back on track", "morning recap for this project". Not for calendar/personal-schedule briefs — use the morning skill for that.
delegate
Route work off the expensive tier -- a Codex CLI worker, a Haiku/Sonnet subagent, or local Ollama -- instead of running it inline. Use for read-only investigation that would flood the transcript (grep sweeps, log trawls, triage) and to dispatch already-specified implementation, on "hand this off", "give it to codex", "use a worker". Code changes still need a GitHub issue first -- route through polyhydra-issue-router, this is not a way to implement without one.
dont-reinvent-the-wheel
Before scaffolding a "new" idea (tool, automation, script), search the user's own ecosystem and known external projects for prior art so work is not duplicated. Triggers on "new idea", "what if we built", "let's create a", "is there something already for this" -- any moment a fresh tool/automation/skill is about to be proposed. Not for routine bug fixes or well-scoped features in an already-identified codebase.
haiku-storm
Fan out a batch of independent, well-specified housekeeping/recon/mechanical work across several parallel lanes at once instead of working through it serially. Lanes dispatch to Codex Luna by default, with Haiku reserved for lanes that need Claude Code's own tool surface (MCP servers, nested Agent calls, a named subagent type). Use on "haiku storm", "storm this", or when there's a pile of low-ambiguity work (close stale issues, clean up merged worktrees, survey a backlog, verify-and-report tasks) that splits cleanly into 3-5 independent lanes. Not for work that needs judgment, touches files another in-flight task is actively editing, or requires a GitHub issue that doesn't exist yet.
handoff
Split part of the current conversation into a durable handoff file and launch a fresh session seeded with it, so the old thread can close instead of dragging its context forward. Triggers on "handoff", "hand this off to a new thread", "close this thread and start fresh", "this thread is getting long". Also use when a new session is pointed at a handoff file, to orient before starting work.
projects
Navigate ~/projects -- list hubs with purpose and health, initialize a new hub (single-repo, or multi-repo via project-home), print a briefing block for a new conversation, give a "catch me up" recent/horizon/goals summary for one project, recommend what to work on next (git-dirty plus PR plus live-session signal), launch a session in a project, capture a stray idea with no home yet, park or activate backlog entries. Use for "what should I work on", "list my projects", "set me up on X", "start a session in X", "new day", "catch me up on X", "standup", "what happened on X", "new idea", "jot this down", "note this idea for later", or naming a project under ~/projects.
