A. Skill Invocation

• This skill is invoked by mentioning $gsd-complete-milestone.
• Treat all user text after $gsd-complete-milestone 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): Codex exposes two spawn_agent schemas:

• agent_type-capable schema (e.g. multi_agent_v2): spawn_agent accepts agent_type, message, reasoning_effort, fork_context, etc. — typed GSD agent dispatch is available.
• Generic schema (multi_agent_v1): spawn_agent accepts only message, items, fork_context — there is no agent_type field. Typed GSD agent dispatch is unavailable in this session.

Before spawning, inspect the spawn_agent tool's visible parameter schema (via tool_search or the tool list) to determine which form is active.

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="...") → 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).

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 → 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>

Mark milestone {{version}} complete, archive to milestones/, and update ROADMAP.md and REQUIREMENTS.md.

Purpose: Create historical record of shipped version, archive milestone artifacts (roadmap + requirements), and prepare for next milestone. Output: Milestone archived (roadmap + requirements), PROJECT.md evolved, git tagged.

<execution_context> Load these files NOW (before proceeding):

• @/home/user/projects/temp/ai-apps/.personal-projects/registry-atlas/.codex/gsd-core/workflows/complete-milestone.md (main workflow)
• @/home/user/projects/temp/ai-apps/.personal-projects/registry-atlas/.codex/gsd-core/templates/milestone-archive.md (archive template) </execution_context>

**Project files:** - `.planning/ROADMAP.md` - `.planning/REQUIREMENTS.md` - `.planning/STATE.md` - `.planning/PROJECT.md`

User input:

• Version: {{version}} (e.g., "1.0", "1.1", "2.0")

Follow complete-milestone.md workflow:

0. Check for audit:

   • Look for .planning/v{{version}}-MILESTONE-AUDIT.md
   • If missing or stale: recommend $gsd-audit-milestone first
   • If audit status is gaps_found: recommend closing the gaps inline (the audit output already enumerates them — insert closure phases via $gsd-phase --insert <N> plus the standard discuss/plan/execute chain) before proceeding.
   • If audit status is passed: proceed to step 1

   ## Pre-flight Check
   
   {If no v{{version}}-MILESTONE-AUDIT.md:}
   ⚠ No milestone audit found. Run `$gsd-audit-milestone` first to verify
   requirements coverage, cross-phase integration, and E2E flows.
   
   {If audit has gaps:}
   ⚠ Milestone audit found gaps. The audit output already enumerates the
   unsatisfied requirements, cross-phase issues, and broken flows — insert
   a closure phase per gap with `$gsd-phase --insert <N>` and run the
   standard `$gsd-discuss-phase` → `$gsd-plan-phase` → `$gsd-execute-phase`
   chain. Or proceed anyway to accept the gaps as tech debt.
   
   {If audit passed:}
   ✓ Milestone audit passed. Proceeding with completion.
   

1. Verify readiness:

   • Check all phases in milestone have completed plans (SUMMARY.md exists)
   • Present milestone scope and stats
   • Wait for confirmation

2. Gather stats:

   • Count phases, plans, tasks
   • Calculate git range, file changes, LOC
   • Extract timeline from git log
   • Present summary, confirm

3. Extract accomplishments:

   • Read all phase SUMMARY.md files in milestone range
   • Extract 4-6 key accomplishments
   • Present for approval

4. Archive milestone:

   • Create .planning/milestones/v{{version}}-ROADMAP.md
   • Extract full phase details from ROADMAP.md
   • Fill milestone-archive.md template
   • Update ROADMAP.md to one-line summary with link

5. Archive requirements:

   • Create .planning/milestones/v{{version}}-REQUIREMENTS.md
   • Mark all v1 requirements as complete (checkboxes checked)
   • Note requirement outcomes (validated, adjusted, dropped)
   • Delete .planning/REQUIREMENTS.md (fresh one created for next milestone)

6. Update PROJECT.md:

   • Add "Current State" section with shipped version
   • Add "Next Milestone Goals" section
   • Archive previous content in <details> (if v1.1+)

7. Commit and tag:

   • Stage: MILESTONES.md, PROJECT.md, ROADMAP.md, STATE.md, archive files
   • Commit: chore: archive v{{version}} milestone
   • Tag: git tag -a v{{version}} -m "[milestone summary]"
   • Ask about pushing tag

8. Offer next steps:

   • $gsd-new-milestone — start next milestone (questioning → research → requirements → roadmap)

<success_criteria>

• Milestone archived to .planning/milestones/v{{version}}-ROADMAP.md
• Requirements archived to .planning/milestones/v{{version}}-REQUIREMENTS.md
• .planning/REQUIREMENTS.md deleted (fresh for next milestone)
• ROADMAP.md collapsed to one-line entry
• PROJECT.md updated with current state
• Git tag v{{version}} created (if git.create_tag enabled)
• Commit successful
• User knows next steps (including need for fresh requirements) </success_criteria>

<critical_rules>

• Load workflow first: Read complete-milestone.md before executing
• Verify completion: All phases must have SUMMARY.md files
• User confirmation: Wait for approval at verification gates
• Archive before deleting: Always create archive files before updating/deleting originals
• One-line summary: Collapsed milestone in ROADMAP.md should be single line with link
• Context efficiency: Archive keeps ROADMAP.md and REQUIREMENTS.md constant size per milestone
• Fresh requirements: Next milestone starts with $gsd-new-milestone which includes requirements definition </critical_rules>
