Activation

This is the description your AI agent reads to decide when to run this skill — the better it matches your request, the more reliably it fires.

Create detailed phase plan (PLAN.md) with verification loop
59 charsno explicit “when” trigger
Intermediate

Key capabilities

  • Create executable phase prompts (PLAN.md)
  • Integrate research into planning
  • Perform verification loops for plans
  • Spawn gsd-planner and gsd-plan-checker agents
  • Parse arguments and validate phases

How it works

The skill orchestrates research, planning, and verification, spawning sub-agents for specific tasks and iterating until the plan passes verification or reaches max iterations.

Inputs & outputs

You give it
Phase number as GSD_ARGS (optional), with flags like --research, --skip-research, --gaps, --skip-verify, --prd <file>, or --reviews
You get back
PLAN.md files for a roadmap phase

When to use gsd-plan-phase

  • Planning a new development phase
  • Structuring a complex feature implementation
  • Creating a verification loop for a task

About this skill

<codex_skill_adapter>

A. Skill Invocation

  • This skill is invoked by mentioning $gsd-plan-phase.
  • Treat all user text after $gsd-plan-phase as {{GSD_ARGS}}.
  • If no arguments are present, treat {{GSD_ARGS}} as empty.

B. AskUserQuestion → request_user_input Mapping

GSD workflows use AskUserQuestion (Claude Code syntax). Translate to Codex request_user_input:

Parameter mapping:

  • headerheader
  • questionquestion
  • Options formatted as "Label" — description{label: "Label", description: "description"}
  • Generate id from header: lowercase, replace spaces with underscores

Batched calls:

  • AskUserQuestion([q1, q2]) → single request_user_input with multiple entries in questions[]

Multi-select workaround:

  • Codex has no multiSelect. Use sequential single-selects, or present a numbered freeform list asking the user to enter comma-separated numbers.

Execute mode fallback:

  • When request_user_input is rejected (Execute mode), present a plain-text numbered list and pick a reasonable default.

C. Task() → spawn_agent Mapping

GSD workflows use Task(...) (Claude Code syntax). Translate to Codex collaboration tools:

Direct mapping:

  • Task(subagent_type="X", prompt="Y")spawn_agent(agent_type="X", message="Y")
  • Task(model="...") → omit (Codex uses per-role config, not inline model selection)
  • fork_context: false by default — GSD agents load their own context via <files_to_read> blocks

Parallel fan-out:

  • Spawn multiple agents → collect agent IDs → wait(ids) for all to complete

Result parsing:

  • Look for structured markers in agent output: CHECKPOINT, PLAN COMPLETE, SUMMARY, etc.
  • close_agent(id) after collecting results from each agent </codex_skill_adapter>
<objective> Create executable phase prompts (PLAN.md files) for a roadmap phase with integrated research and verification.

Default flow: Research (if needed) → Plan → Verify → Done

Orchestrator role: Parse arguments, validate phase, research domain (unless skipped), spawn gsd-planner, verify with gsd-plan-checker, iterate until pass or max iterations, present results. </objective>

<execution_context> @C:/Users/gusta/OneDrive/Documentos/gerenciador-de-quadras/.codex/get-shit-done/workflows/plan-phase.md @C:/Users/gusta/OneDrive/Documentos/gerenciador-de-quadras/.codex/get-shit-done/references/ui-brand.md </execution_context>

<runtime_note> Copilot (VS Code): Use vscode_askquestions wherever this workflow calls AskUserQuestion. They are equivalent — vscode_askquestions is the VS Code Copilot implementation of the same interactive question API. Do not skip questioning steps because AskUserQuestion appears unavailable; use vscode_askquestions instead. </runtime_note>

<context> Phase number: {{GSD_ARGS}} (optional — auto-detects next unplanned phase if omitted)

Flags:

  • --research — Force re-research even if RESEARCH.md exists
  • --skip-research — Skip research, go straight to planning
  • --gaps — Gap closure mode (reads VERIFICATION.md, skips research)
  • --skip-verify — Skip verification loop
  • --prd <file> — Use a PRD/acceptance criteria file instead of discuss-phase. Parses requirements into CONTEXT.md automatically. Skips discuss-phase entirely.
  • --reviews — Replan incorporating cross-AI review feedback from REVIEWS.md (produced by /gsd-review)
  • --text — Use plain-text numbered lists instead of TUI menus (required for /rc remote sessions)

Normalize phase input in step 2 before any directory lookups. </context>

<process> Execute the plan-phase workflow from @C:/Users/gusta/OneDrive/Documentos/gerenciador-de-quadras/.codex/get-shit-done/workflows/plan-phase.md end-to-end. Preserve all workflow gates (validation, research, planning, verification loop, routing). </process>

When not to use it

  • When a detailed plan is not needed
  • When the user wants to skip the verification loop

Limitations

  • Requires `AskUserQuestion` or `vscode_askquestions` for interactive mode

How it compares

This skill automates the creation of detailed, verified plans with integrated research and feedback loops, providing a more structured and reliable planning process than manual methods.
