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
Routes to the add-phase workflow which handles:
Phase number calculation (next sequential integer)
Directory creation with slug generation
Roadmap structure updates
STATE.md roadmap evolution tracking
Roadmap and state are resolved in-workflow via init phase-op and targeted tool calls.
The workflow handles all logic including:
Argument parsing and validation
Roadmap existence checking
Current milestone identification
Next phase number calculation (ignoring decimals)
Slug generation from description
Phase directory creation
Roadmap entry insertion
STATE.md updates
1---2name: gsd-add-phase3description: Add phase to end of current milestone in roadmap4---56<codex_skill_adapter>7## A. Skill Invocation8- This skill is invoked by mentioning `$gsd-add-phase`.9- Treat all user text after `$gsd-add-phase` as `{{GSD_ARGS}}`.10- If no arguments are present, treat `{{GSD_ARGS}}` as empty.1112## B. AskUserQuestion → request_user_input Mapping13GSD workflows use `AskUserQuestion` (Claude Code syntax). Translate to Codex `request_user_input`:1415Parameter mapping:16- `header` → `header`17- `question` → `question`18- Options formatted as `"Label" — description` → `{label: "Label", description: "description"}`19- Generate `id` from header: lowercase, replace spaces with underscores2021Batched calls:22- `AskUserQuestion([q1, q2])` → single `request_user_input` with multiple entries in `questions[]`2324Multi-select workaround:25- Codex has no `multiSelect`. Use sequential single-selects, or present a numbered freeform list asking the user to enter comma-separated numbers.2627Execute mode fallback:28- When `request_user_input` is rejected (Execute mode), present a plain-text numbered list and pick a reasonable default.2930## C. Task() → spawn_agent Mapping31GSD workflows use `Task(...)` (Claude Code syntax). Translate to Codex collaboration tools:3233Direct mapping:34- `Task(subagent_type="X", prompt="Y")` → `spawn_agent(agent_type="X", message="Y")`35- `Task(model="...")` → omit (Codex uses per-role config, not inline model selection)36- `fork_context: false` by default — GSD agents load their own context via `<files_to_read>` blocks3738Parallel fan-out:39- Spawn multiple agents → collect agent IDs → `wait(ids)` for all to complete4041Result parsing:42- Look for structured markers in agent output: `CHECKPOINT`, `PLAN COMPLETE`, `SUMMARY`, etc.43- `close_agent(id)` after collecting results from each agent44</codex_skill_adapter>4546<objective>47Add a new integer phase to the end of the current milestone in the roadmap.4849Routes to the add-phase workflow which handles:50- Phase number calculation (next sequential integer)51- Directory creation with slug generation52- Roadmap structure updates53- STATE.md roadmap evolution tracking54</objective>5556<execution_context>57@/Users/richardhightower/clients/spillwave/src/agent-brain/.codex/get-shit-done/workflows/add-phase.md58</execution_context>5960<context>61Arguments: {{GSD_ARGS}} (phase description)6263Roadmap and state are resolved in-workflow via `init phase-op` and targeted tool calls.64</context>6566<process>67**Follow the add-phase workflow** from `@/Users/richardhightower/clients/spillwave/src/agent-brain/.codex/get-shit-done/workflows/add-phase.md`.6869The workflow handles all logic including:701.
