## A. Skill Invocation
- This skill is invoked by mentioning `$gsd-update`.
- Treat all user text after `$gsd-update` 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.
- Resolved `reasoning_effort="low|medium|high|xhigh"` (`xhigh` is a GSD/Codex tier, not a generic runtime enum) → pass `reasoning_effort`
  to `spawn_agent` when the runtime/tool supports it. Omit missing, empty,
  inherited, or unsupported values; do not invent one-off effort literals in
  workflow prose.
- `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

<objective>
Check for GSD updates, install if available, and display what changed.

Routes to the update workflow which handles:
- Version detection (local vs global installation)
- npm version checking
- Changelog fetching and display
- User confirmation with clean install warning
- Update execution and cache clearing
- Restart reminder
</objective>

<flags>
- **--sync**: Sync managed GSD skills across runtime roots so multi-runtime users stay aligned after an update. Runs the sync-skills workflow (--from, --to, --dry-run, --apply flags supported).
- **--reapply**: Reapply local modifications after a GSD update. Uses three-way comparison (pristine baseline, user-modified backup, newly installed version) to merge user customizations back. Runs the reapply-patches workflow.
- **(no flag)**: Standard update — check for new version, show changelog, install.
</flags>

<process>
Parse the first token of {{GSD_ARGS}}:
- If it is `--sync`: strip the flag, execute the sync-skills workflow (passing remaining args for --from/--to/--dry-run/--apply).
- If it is `--reapply`: strip the flag, execute the reapply-patches workflow.
- Otherwise: execute the update workflow end-to-end.
