gsd-plan
Plan a phase — optional discussion → research → plan → verify
Best use case
gsd-plan is best used when you need a repeatable AI agent workflow instead of a one-off prompt.
Plan a phase — optional discussion → research → plan → verify
Teams using gsd-plan should expect a more consistent output, faster repeated execution, less prompt rewriting.
When to use this skill
- You want a reusable workflow that can be run more than once with consistent structure.
When not to use this skill
- You only need a quick one-off answer and do not need a reusable workflow.
- You cannot install or maintain the underlying files, dependencies, or repository context.

## A. Skill Invocation
- Invoked by mentioning `$gsd-SLUG`.
- Treat all user text after `$gsd-SLUG` as `{{GSD_ARGS}}`.
## B. AskUserQuestion → request_user_input Mapping
- `header` → `header`, `question` → `question`
- Execute mode fallback: plain-text numbered list, pick reasonable default
## C. Task() → spawn_agent Mapping
- `Task(subagent_type="X", prompt="Y")` → `spawn_agent(agent_type="X", message="Y")`
- `Task(model="...")` → omit
- Parallel: spawn → collect IDs → `wait(ids)` → `close_agent(id)`

<objective>
Create an executable PLAN.md for a roadmap phase.
Default flow: Research (if needed) → Plan → Verify → Done
Flags:
- `--discuss` — Clarify assumptions before planning
- `--ui` — Generate UI design contract before planning
- `--auto` — Skip questions, use recommended defaults
- `--skip-research` — Go straight to planning
- `--gaps` — Gap closure mode from VERIFICATION.md
- `--prd <file>` — Parse PRD into CONTEXT.md
- `add-phase "desc"` — Append future phase to roadmap
- `insert-phase N "desc"` — Insert future phase after N
- `remove-phase N` — Remove future phase safely
After: run gsd-run <phase> to execute.
</objective>
<context>
Phase: {{GSD_ARGS}} (auto-detects next unplanned if omitted)
</context>
<process>
Route by intent:
- `add-phase` → add-phase workflow
- `insert-phase` → insert-phase workflow
- `remove-phase` → remove-phase workflow
- `--ui` → ui-phase workflow
- `--gaps` → plan-milestone-gaps workflow
- `--discuss` → discuss-phase workflow first, then plan-phase
- otherwise → execute plan-phase workflow end-to-end
