Agent skills for Claude Code

Insert urgent work as decimal phase (e.g., 72.1) between existing phases

Interactive command center for managing multiple phases from one terminal

Plan an MVP-mode phase — captures an "As a / I want to / So that" user story, runs SPIDR splitting, then delegates to plan-phase

Start a new milestone cycle — update PROJECT.md and route to requirements

Create an isolated workspace with repo copies and independent .planning/

Automatically advance to the next logical step in the GSD workflow

Create phases to close all gaps identified by milestone audit

Create detailed phase plan (PLAN.md) with verification loop

Capture a forward-looking idea with trigger conditions — surfaces automatically at the right milestone

Generate developer behavioral profile and create Claude-discoverable artifacts

Check project progress, show context, and route to next action (execute or plan).

Execute a quick task with GSD guarantees (atomic commits, state tracking) but skip optional agents

Schedule a future resume of work - e.g. '/gsd:resume-at 09:00', '/gsd:resume-at +2h', or '/gsd:resume-at 04:00 --cmd /gsd:execute-phase 9

Resume work from previous session with full context restoration

Package sketch design findings into a persistent project skill for future build conversations

Socratic spec refinement — clarify WHAT a phase delivers with ambiguity scoring before discuss-phase.

Spike an idea through experiential exploration, or propose what to spike next (frontier mode)

Package spike findings into a persistent project skill for future build conversations

Manage parallel workstreams — list, create, switch, status, progress, complete, and resume
