<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:

• header → header
• question → question
• 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 or unavailable, you MUST stop and present the questions as a plain-text numbered list, then wait for the user's reply. Do NOT pick a default and continue (#3018).
• You may only proceed without a user answer when one of these is true: (a) the invocation included an explicit non-interactive flag (--auto or --all), (b) the user has explicitly approved a specific default for this question, or (c) the workflow's documented contract says defaults are safe (e.g. autonomous lifecycle paths).
• Do NOT write workflow artifacts (CONTEXT.md, DISCUSSION-LOG.md, PLAN.md, checkpoint files) until the user has answered the plain-text questions or one of (a)-(c) above applies. Surfacing the questions and waiting is the correct response — silently defaulting and writing artifacts is the #3018 failure mode.

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. spawn_agent has no inline model parameter; GSD embeds the resolved per-agent model directly into each agent's .toml at install time so model_overrides from .planning/config.json and ~/.gsd/defaults.json are honored automatically by Codex's agent router.
• fork_context: false by default — GSD agents load their own context via <files_to_read> blocks
• Task(isolation="worktree") / Agent(isolation="worktree") → no direct Codex mapping. Codex spawn_agent does not create or bind a git worktree automatically. Workflows that require this isolation must fail closed or use an explicit manual worktree protocol before spawning (#3360).

Spawn restriction:

• Codex restricts spawn_agent to cases where the user has explicitly requested sub-agents. When automatic spawning is not permitted, do the work inline in the current agent rather than attempting to force a spawn.

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

Research-only mode (--research-phase <N>): Spawn gsd-phase-researcher for phase N, write RESEARCH.md, then exit before the planner runs. Useful for cross-phase research, doc review before committing to a planning approach, and correction-without-replanning loops where iterating on research alone is dramatically cheaper than re-spawning the planner. Replaces the deleted $gsd-research-phase command (#3042).

Research-only modifiers:

• No flag — when RESEARCH.md already exists, prompt the user to choose update / view / skip.
• --research — force-refresh: re-spawn the researcher unconditionally, no prompt. Skips the existing-RESEARCH.md menu.
• --view — view-only: print existing RESEARCH.md to stdout. Does not spawn the researcher. Cheapest mode for the correction-without-replanning loop. If no RESEARCH.md exists yet, errors with a hint to drop --view.

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>

<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)
• --mvp — Vertical MVP mode. Planner organizes tasks as feature slices (UI→API→DB) instead of horizontal layers. On Phase 1 of a new project, also emits SKELETON.md (Walking Skeleton). Can be persisted on a phase via **Mode:** mvp in ROADMAP.md.

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

<process> Execute end-to-end. Preserve all workflow gates (validation, research, planning, verification loop, routing). </process>
