Gsd Quick Batch

<codex_skill_adapter>

A. Skill Invocation

• This skill is invoked by mentioning $gsd-quick-batch.
• Treat all user text after $gsd-quick-batch 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, activate TEXT_MODE: append --text to {{GSD_ARGS}} so the workflow's built-in text-mode branching takes over. Present every AskUserQuestion call as a plain-text numbered list, then stop and wait for the user's reply. Do NOT pick a default and continue (#3018 / #3808).
• 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:

Schema detection (required first step): Before spawning, inspect the spawn_agent tool's visible parameter schema (via tool_search or the tool list). Use the presence of agent_type only to choose typed dispatch versus the generic-agent workaround. Detect optional fields independently: model, reasoning_effort, task_name, fork_turns, and fork_context may be added or removed without agent_type changing. Never infer one field from a schema/version label or from the presence of another field.

• agent_type-capable schema: spawn_agent advertises agent_type — typed GSD agent dispatch is available.
• Generic schema: spawn_agent does not advertise agent_type — typed GSD agent dispatch is unavailable in this session, even if other optional fields are present.

Typed mapping (agent_type-capable schema only):

• Task(subagent_type="X", prompt="Y") → spawn_agent(agent_type="X", message="Y")
• Agent(subagent_type="X", prompt="Y") → spawn_agent(agent_type="X", message="Y")
• Task(model="{resolved_model}") → pass model="{resolved_model}" when the visible spawn_agent schema advertises model and the resolved value is explicit. This is how model_profile tier routing, including adaptive, reaches the child agent. Omit model only when the schema does not advertise model, or when the value is missing, empty, or "inherit"; omission deliberately inherits the session/static agent configuration. Explicit model_overrides may also be embedded in agent .toml files, but ordinary profile-resolved models are not, so a TOML file is not a reason to discard an available inline value.
• Before each typed spawn, obtain the paired effort for its role with gsd_run query resolve-model <subagent_type> --pick effort when the workflow has not already exposed it. The resolver's unified effort field maps to the Codex spawn argument reasoning_effort; do not look for a resolver field named reasoning_effort. Pass it when the visible spawn_agent schema advertises reasoning_effort. Omit the field when it is not advertised, or when the value is missing, empty, "inherit", or unsupported; do not invent one-off effort literals in workflow prose.
• fork_context: false by default — GSD agents load their own context via <required_reading> blocks
• task_name — when advertised, provide a descriptive name for each spawned task
• fork_turns — when advertised, controls turn-forking depth; coexists with fork_context (not a replacement)
• Task(isolation="worktree") / Agent(isolation="worktree") → no direct spawn_agent mapping, but Codex declares dispatch.isolation: orchestrator-worktree (#2584). Codex spawn_agent still does not create or bind a git worktree; instead GSD itself creates the worktree and process-spawns the executor into it with codex exec --cd <dir>, performing every git operation on the executor's behalf (its workspace-write sandbox makes .git read-only). Workflows must therefore never fabricate a manual worktree protocol — route through the negotiated isolation adapter, which still fails closed for hosts declaring none (#3360).

Generic-agent workaround (multi_agent_v1 schema — NO agent_type field): When only the generic multi_agent_v1 schema is available, typed GSD agent dispatch (gsd-planner, gsd-executor, etc.) is NOT possible. This is a known Codex limitation (openai/codex#15250). This workaround is NOT equivalent to typed gsd-planner/gsd-executor execution — GSD agents carry project-aware prompts, audit logging, and workflow context that a generic subagent lacks. Use the following fallback:

1. Resolve your active Codex config root — the directory that contains your config.toml. This directory is determined in priority order: $CODEX_HOME (if set), the path given by --config-dir (if passed on invocation), a local .codex directory in the current project (if --local was used), or the default global config directory. Read agents/<agent-name>.toml relative to that config root to extract the agent's system instructions.
2. Inject those instructions as a role-preamble into a generic spawn_agent(message=...) call.
3. Label results and logs clearly as "generic-agent workaround" so the orchestrator and user know full typed-agent guarantees are not in effect.
4. Where typed dispatch is mandatory for correctness (e.g. worktree isolation), fail closed and report the schema limitation rather than silently degrading.

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.
• In some Codex sessions, multi-agent tooling can be deferred. If spawn_agent is not currently visible, discover tools first via tool_search before defaulting to inline execution.

Parallel fan-out:

• Spawn multiple agents → collect agent IDs → collaboration.wait_agent(timeout_ms=...) for each to complete
• Do NOT use functions.wait(cell_id=...) — that is an unrelated exec-cell tool, not the collaboration wait
