**This is an INTERNAL workflow — NOT a user-facing command.**
There is no `/gsd-transition` command. This workflow is invoked automatically by
`execute-phase` during auto-advance, or inline by the orchestrator after phase
verification. Users should never be told to run `/gsd-transition`.
**Valid user commands for phase progression:**
- `/gsd:discuss-phase {N}` — discuss a phase before planning
- `/gsd:plan-phase {N}` — plan a phase
- `/gsd:execute-phase {N}` — execute a phase
- `/gsd:progress` — see roadmap progress
**Read these files NOW:**
1. `.planning/STATE.md`
2. `.planning/PROJECT.md`
3. `.planning/ROADMAP.md`
4. Current phase's plan files (`*-PLAN.md`)
5. Current phase's summary files (`*-SUMMARY.md`)
Mark current phase complete and advance to next. This is the natural point where progress tracking and PROJECT.md evolution happen.
"Planning next phase" = "current phase is done"
**Invocation mode — read this FIRST.** This workflow runs two ways:
1. **Standalone transition** (normal path): the phase is being marked complete AND
transitioned by this workflow. Run EVERY step below in order — `verify_completion`,
`update_roadmap_and_state` (which calls `gsd_run query phase.complete`), then the
post-processing.
2. **Post-completion delegation** (invoked by `execute-phase` after its auto-chain
completion — #1526): `phase.complete` was already called by execute-phase's
`update_roadmap` step and verification already passed in execute-phase's
`verify_phase_goal`. SKIP `verify_completion` and `update_roadmap_and_state`
(re-running `phase.complete` would double-write STATE.md/ROADMAP.md). Run
`cleanup_handoff` (stale `.continue-here` handoffs are still cleared post-completion),
then BEGIN at `evolve_project` and run every step from there through
`offer_next_phase` (this is the post-processing parity set: graduation scan,
session-continuity, project-reference, accumulated-context, current-position/progress).
`archive_prompts` is a documented no-op in either mode.
Detect post-completion mode when the caller states that phase completion and
verification have already run. When in doubt, run standalone (mode 1) — it is
idempotent enough to be safe, just slower.
Before transition, read project state:
```bash
cat .planning/STATE.md 2>/dev/null || true
cat .planning/PROJECT.md 2>/dev/null || true
```
Parse current position to verify we're transitioning the right phase.
Note accumulated context that may need updating after transition.
Check current phase has all plan summaries:
```bash
(ls .planning/phases/XX-current/*-PLAN.md 2>/dev/null || true) | sort
(ls .planning/phases/XX-current/*-SUMMARY.md 2>/dev/null || true) | sort
```
**Verification logic:**
- Count PLAN files
- Count SUMMARY files
- If counts match: all plans complete
- If counts don't match: incomplete
```bash
cat .planning/config.json 2>/dev/null || true
```
**Check for verification debt in this phase:**
```bash
_GSD_SHIM_NAME="gsd-tools.cjs"; _GSD_RUNTIME_ROOT="${RUNTIME_DIR:-$(git rev-parse --show-toplevel 2>/dev/null || pwd)}"; GSD_TOOLS="${_GSD_RUNTIME_ROOT}/gsd-core/bin/${_GSD_SHIM_NAME}"; _gsd_at() { for _p; do if [ -f "$_p" ]; then GSD_TOOLS="$_p"; return 0; fi; done; return 1; }; if _gsd_at "${_GSD_RUNTIME_ROOT}/gsd-core/bin/${_GSD_SHIM_NAME}" "${_GSD_RUNTIME_ROOT}/.claude/gsd-core/bin/${_GSD_SHIM_NAME}" "${_GSD_RUNTIME_ROOT}/.codex/gsd-core/bin/${_GSD_SHIM_NAME}"; then gsd_run() { node "$GSD_TOOLS" "$@"; }; elif unset -f gsd_run; _G="$(command -v gsd_run)"; then GSD_TOOLS="$_G"; gsd_run() { "$GSD_TOOLS" "$@"; }; elif _gsd_at "${CLAUDE_CONFIG_DIR:-$HOME/.claude}/gsd-core/bin/${_GSD_SHIM_NAME}" "${HERMES_HOME:-$HOME/.hermes}/gsd-core/bin/${_GSD_SHIM_NAME}" "${CURSOR_CONFIG_DIR:-$HOME/.cursor}/gsd-core/bin/${_GSD_SHIM_NAME}" "${CODEX_HOME:-$HOME/.codex}/gsd-core/bin/${_GSD_SHIM_NAME}" "${GEMINI_CONFIG_DIR:-$HOME/.gemini}/gsd-core/bin/${_GSD_SHIM_NAME}" "${COPILOT_CONFIG_DIR:-$HOME/.copilot}/gsd-core/bin/${_GSD_SHIM_NAME}" "${WINDSURF_CONFIG_DIR:-$HOME/.codeium/windsurf}/gsd-core/bin/${_GSD_SHIM_NAME}" "${AUGMENT_CONFIG_DIR:-$HOME/.augment}/gsd-core/bin/${_GSD_SHIM_NAME}" "${TRAE_CONFIG_DIR:-$HOME/.trae}/gsd-core/bin/${_GSD_SHIM_NAME}" "${QWEN_CONFIG_DIR:-$HOME/.qwen}/gsd-core/bin/${_GSD_SHIM_NAME}" "${CODEBUDDY_CONFIG_DIR:-$HOME/.codebuddy}/gsd-core/bin/${_GSD_SHIM_NAME}" "${CLINE_CONFIG_DIR:-$HOME/.cline}/gsd-core/bin/${_GSD_SHIM_NAME}" "${GROK_AGENTS_HOME:-$HOME/.agents}/gsd-core/bin/${_GSD_SHIM_NAME}" "${ANTIGRAVITY_CONFIG_DIR:-$HOME/.gemini/antigravity}/gsd-core/bin/${_GSD_SHIM_NAME}" "${OPENCODE_CONFIG_DIR:-${XDG_CONFIG_HOME:-$HOME/.config}/opencode}/gsd-core/bin/${_GSD_SHIM_NAME}" "${KILO_CONFIG_DIR:-${XDG_CONFIG_HOME:-$HOME/.config}/kilo}/gsd-core/bin/${_GSD_SHIM_NAME}"; then gsd_run() { node "$GSD_TOOLS" "$@"; }; else echo "ERROR: gsd-tools.cjs not found at $GSD_TOOLS and gsd_run is not on PATH.

# #3492: resolve THIS phase's own report through the single shared seam
# (src/verification.cts resolveVerificationFile) instead of a blind
# `*-VERIFICATION.md` glob — a stray ad-hoc worksheet (e.g.
# `03-CORRECTION-VERIFICATION.md`) alphabetically outranks the real report
# and previously fed this awk parse the wrong file.
VERIFICATION_FILE=$(gsd_run query verification.resolve-file .planning/phases/XX-current --raw 2>/dev/null)
# awk extracts only the status: field between the two --- fences to avoid
# false positives from historical body text (e.g. previous_status: gaps_found).
# FNR (not NR) re-arms the frontmatter scan per input file: NR only ever arms
# on the very FIRST line of the very first file, so a multi-file input would
# silently read empty status for every file after the first. The resolver
# above always hands back a single path, but the parse stays correct even if
# that ever changes.

"$VERIFICATION_FILE" 2>/dev/null | head -1)
```
**If VERIFY_STATUS is not `passed`:**
Stop before confirming:
```
Verification incomplete: ${VERIFY_STATUS:-missing}
Resolve before transition. Review: `/gsd:audit-uat`
```
This preliminary check blocks obviously unresolved verification early, ahead
of the authoritative gate below. `gsd_run query phase.complete` (in
`update_roadmap_and_state`) remains the authoritative stale-aware gate and
fail-closes unless canonical verification status is `passed`.
**If all plans complete:**
```
⚡ Auto-approved: Transition Phase [X] → Phase [X+1]
Phase [X] complete — all [Y] plans finished.
Proceeding to mark done and advance...
```
Proceed directly to cleanup_handoff step.
Ask: "Phase [X] complete — all [Y] plans finished. Ready to mark done and move to Phase [X+1]?"
Wait for confirmation before proceeding.
**If plans incomplete:**
**SAFETY RAIL: always_confirm_destructive applies here.**
Skipping incomplete plans is destructive — ALWAYS prompt regardless of mode.
Present:
```
Phase [X] has incomplete plans:
- {phase}-01-SUMMARY.md ✓ Complete
- {phase}-02-SUMMARY.md ✗ Missing
- {phase}-03-SUMMARY.md ✗ Missing
⚠️ Safety rail: Skipping plans requires confirmation (destructive action)
Options:
1. Continue current phase (execute remaining plans)
2. Mark complete anyway (skip remaining plans)
3. Review what's left
```
Wait for user decision.
Check for lingering handoffs:
```bash
ls .planning/phases/XX-current/.continue-here*.md 2>/dev/null || true
```
If found, delete them — phase is complete, handoffs are stale.
**Delegate ROADMAP.md and STATE.md updates to `gsd_run query phase.complete`:**
```bash
TRANSITION=$(gsd_run query phase.complete "${current_phase}")
```
The CLI handles:
- Marking the phase checkbox as `[x]` complete with today's date
- Updating plan count to final (e.g., "3/3 plans complete")
- Updating the Progress table (Status → Complete, adding date)
- Advancing STATE.md to next phase (Current Phase, Status → Ready to plan, Current Plan → Not started)
- Detecting if this is the last phase in the milestone
Extract from result: `completed_phase`, `plans_executed`, `next_phase`, `next_phase_name`, `is_last_phase`.
If prompts were generated for the phase, they stay in place.
The `completed/` subfolder pattern from create-meta-prompts handles archival.
Evolve PROJECT.md to reflect learnings from completed phase.
**Read phase summaries:**
```bash
_SUMMARIES=( .planning/phases/XX-current/*-SUMMARY.md )
if [ -e "${_SUMMARIES[0]}" ]; then cat "${_SUMMARIES[@]}"; fi
```
**Assess requirement changes:**
1. **Requirements validated?**
- Any Active requirements shipped in this phase?
- Move to Validated with phase reference: `- ✓ [Requirement] — Phase X`
2. **Requirements invalidated?**
- Any Active requirements discovered to be unnecessary or wrong?
- Move to Out of Scope with reason: `- [Requirement] — [why invalidated]`
3. **Requirements emerged?**
- Any new requirements discovered during building?
- Add to Active: `- [ ] [New requirement]`
4. **Decisions to log?**
- Extract decisions from SUMMARY.md files
- Add to Key Decisions table with outcome if known
5. **"What This Is" still accurate?**
- If the product has meaningfully changed, update the description
- Keep it current and accurate
**Update PROJECT.md:**
Make the edits inline. Update "Last updated" footer:
```markdown
---
*Last updated: [date] after Phase [X]*
```
**Example evolution:**
Before:
```markdown
### Active
- [ ] JWT authentication
- [ ] Real-time sync < 500ms
- [ ] Offline mode
### Out of Scope
- OAuth2 — complexity not needed for v1
```
After (Phase 2 shipped JWT auth, discovered rate limiting needed):
```markdown
### Validated
- ✓ JWT authentication — Phase 2
### Active
- [ ] Real-time sync < 500ms
- [ ] Offline mode
- [ ] Rate limiting on sync endpoint
### Out of Scope
- OAuth2 — complexity not needed for v1
```
**Step complete when:**
- [ ] Phase summaries reviewed for learnings
- [ ] Validated requirements moved from Active
- [ ] Invalidated requirements moved to Out of Scope with reason
- [ ] Emerged requirements added to Active
- [ ] New decisions logged with rationale
- [ ] "What This Is" updated if product changed
- [ ] "Last updated" footer reflects this transition
Scan LEARNINGS.md files from recent phases for recurring patterns and surface promotion candidates to the developer.
**Invoke the graduation helper:**
```text
@~/.claude/gsd-core/workflows/graduation.md
```
This step is fully delegated to `graduation.md`. It handles guard checks (feature flag, window size, threshold), clustering, backlog filtering, HITL prompting, promotion writes, and STATE.md updates.
**This step is always non-blocking:** graduation candidates are surfaced for the developer's decision; no action is required to continue the transition. If the graduation scan produces no qualifying clusters, it prints a single `[graduation: no qualifying clusters]` line and returns.
**Step complete when:**
- [ ] graduation.md guard checks passed (or skipped with silent no-op)
- [ ] Recurring clusters surfaced (or `[graduation: no qualifying clusters]` printed)
- [ ] Each cluster resolved as Promote / Defer / Dismiss (or all skipped)
**Note:** Basic position updates (Current Phase, Status, Current Plan, Last Activity) were already handled by `gsd_run query phase.complete` in the update_roadmap_and_state step.
Verify the updates are correct by reading STATE.md. If the progress bar needs updating, use:
```bash
PROGRESS=$(gsd_run query progress.bar --raw)
```
Update the progress bar line in STATE.md with the result.
**Step complete when:**
- [ ] Phase number incremented to next phase (done by phase complete)
- [ ] Plan status reset to "Not started" (done by phase complete)
- [ ] Status shows "Ready to plan" (done by phase complete)
- [ ] Progress bar reflects total completed plans
Update Project Reference section in STATE.md.
```markdown
## Project Reference
See: .planning/PROJECT.md (updated [today])
**Core value:** [Current core value from PROJECT.md]
**Current focus:** [Next phase name]
```
Update the date and current focus to reflect the transition.
Review and update Accumulated Context section in STATE.md.
**Decisions:**
- Note recent decisions from this phase (3-5 max)
- Full log lives in PROJECT.md Key Decisions table
**Blockers/Concerns:**
- Review blockers from completed phase
- If addressed in this phase: Remove from list
- If still relevant for future: Keep with "Phase X" prefix
- Add any new concerns from completed phase's summaries
**Example:**
Before:
```markdown
### Blockers/Concerns
- ⚠️ [Phase 1] Database schema not indexed for common queries
- ⚠️ [Phase 2] WebSocket reconnection behavior on flaky networks unknown
```
After (if database indexing was addressed in Phase 2):
```markdown
### Blockers/Concerns
- ⚠️ [Phase 2] WebSocket reconnection behavior on flaky networks unknown
```
**Step complete when:**
- [ ] Recent decisions noted (full log in PROJECT.md)
- [ ] Resolved blockers removed from list
- [ ] Unresolved blockers kept with phase prefix
- [ ] New concerns from completed phase added
Update Session Continuity section in STATE.md to reflect transition completion.
**Format:**
```markdown
Last session: [today]
Stopped at: Phase [X] complete, ready to plan Phase [X+1]
Resume file: None
```
**Step complete when:**
- [ ] Last session timestamp updated to current date and time
- [ ] Stopped at describes phase completion and next phase
- [ ] Resume file confirmed as None (transitions don't use resume files)
**MANDATORY: Verify milestone status before presenting next steps.**
**Use the transition result from `gsd_run query phase.complete`:**
The `is_last_phase` field from the phase complete result tells you directly:
- `is_last_phase: false` → More phases remain → Go to **Route A**
- `is_last_phase: true` → Last phase done → **Check for workstream collisions first**
The `next_phase` and `next_phase_name` fields give you the next phase details.
If you need additional context, use:
```bash
ROADMAP=$(gsd_run query roadmap.analyze)
```
This returns all phases with goals, disk status, and completion info.
**Section-manifest gate (#2994):** `gsd_run` is already established above (`verify_completion` step) — fetch the dedicated `init.transition` bundle for the workstream-collision-check gate below:
```bash
INIT_TRANSITION=$(gsd_run query init.transition)
if [[ "$INIT_TRANSITION" == @file:* ]]; then INIT_TRANSITION=$(cat "${INIT_TRANSITION#@file:}"); fi
```
Extract from `INIT_TRANSITION`: `other_active_workstreams`, `section_manifest`.
---
If `section_manifest` (from `INIT_TRANSITION`) is `null` or `"workstream-collision-check"` is in its `included` list: read and execute `gsd-core/workflows/transition/steps/workstream-collision-check.md`. Otherwise (flat mode) skip — do not read the file; go directly to **Route B**.
---
**Route A: More phases remain in milestone**
Read ROADMAP.md to get the next phase's name and goal.
**Check if next phase has CONTEXT.md:**
```bash
ls .planning/phases/*[X+1]*/*-CONTEXT.md 2>/dev/null || true
```
**If next phase exists:**
**If CONTEXT.md exists:**
```
Phase [X] marked complete.
Next: Phase [X+1] — [Name]
⚡ Auto-continuing: Plan Phase [X+1] in detail
```
Exit skill and invoke SlashCommand("/gsd:plan-phase [X+1] --auto ${GSD_WS}")
**If CONTEXT.md does NOT exist:**
```
Phase [X] marked complete.
Next: Phase [X+1] — [Name]
⚡ Auto-continuing: Discuss Phase [X+1] first
```
Exit skill and invoke SlashCommand("/gsd:discuss-phase [X+1] --auto ${GSD_WS}")
**If CONTEXT.md does NOT exist:**
```
## ✓ Phase [X] Complete
---
## ▶ Next Up — [${PROJECT_CODE}] ${PROJECT_TITLE}
**Phase [X+1]: [Name]** — [Goal from ROADMAP.md]
`/clear` then:
`/gsd:discuss-phase [X+1] ${GSD_WS}` — gather context and clarify approach
---
**Also available:**
- `/gsd:plan-phase [X+1] ${GSD_WS}` — skip discussion, plan directly
- `/gsd:plan-phase --research-phase [X+1] ${GSD_WS}` — investigate unknowns
---
```
**If CONTEXT.md exists:**
```
## ✓ Phase [X] Complete
---
## ▶ Next Up — [${PROJECT_CODE}] ${PROJECT_TITLE}
**Phase [X+1]: [Name]** — [Goal from ROADMAP.md]
✓ Context gathered, ready to plan
`/clear` then:
`/gsd:plan-phase [X+1] ${GSD_WS}`
---
**Also available:**
- `/gsd:discuss-phase [X+1] ${GSD_WS}` — revisit context
- `/gsd:plan-phase --research-phase [X+1] ${GSD_WS}` — investigate unknowns

```
---
**Route B1: Workstream done, other workstreams still active**
This route is reached when `is_last_phase: true` AND the collision check found
other active workstreams. Do NOT suggest completing the milestone or advancing
to the next milestone — other workstreams are still working.
**Clear auto-advance chain flag** — workstream boundary is the natural stopping point:
```bash
gsd_run query config-set workflow._auto_chain_active false
```
Override auto-advance: do NOT auto-continue to milestone completion.
Present the blocking information and stop.
Present (all modes):
```
## ✓ Phase {X}: {Phase Name} Complete
This workstream's phases are complete. Other workstreams are still active:
| Workstream | Status | Phase | Progress |
|------------|--------|-------|----------|
| {name} | {status} | {current_phase} | {completed_phases}/{phase_count} |
| ... | ... | ... | ... |
---
## Next Steps
Archive this workstream:
`/gsd:workstreams complete {current_ws_name} ${GSD_WS}`
See overall milestone progress:
`/gsd:workstreams progress ${GSD_WS}`
Milestone completion will be available once all workstreams finish.
---
```
Do NOT suggest `/gsd:complete-milestone` or `/gsd:new-milestone`.
Do NOT auto-invoke any further slash commands.
**Stop here.** The user must explicitly decide what to do next.
---
**Route B: All phases complete (milestone ready to close)**
**This route is only reached when:**
- `is_last_phase: true` AND no other active workstreams exist (or flat mode)
**Clear auto-advance chain flag** — milestone boundary is the natural stopping point:
```bash
gsd_run query config-set workflow._auto_chain_active false
```
```
Phase {X} marked complete.
🎉 Milestone {version} is 100% complete — all {N} phases finished!
⚡ Auto-continuing: Complete milestone and archive
```
Exit skill and invoke SlashCommand("/gsd:complete-milestone {version} ${GSD_WS}")
```
## ✓ Phase {X}: {Phase Name} Complete
🎉 Milestone {version} is 100% complete — all {N} phases finished!
---
## ▶ Next Up — [${PROJECT_CODE}] ${PROJECT_TITLE}
**Complete Milestone {version}** — archive and prepare for next
`/clear` then:
`/gsd:complete-milestone {version} ${GSD_WS}`
---
**Also available:**
- Review accomplishments before archiving

```
Progress tracking is IMPLICIT: planning phase N implies phases 1-(N-1) complete. No separate progress step—forward motion IS progress.
If user wants to move on but phase isn't fully complete:
```
Phase [X] has incomplete plans:
- {phase}-02-PLAN.md (not executed)
- {phase}-03-PLAN.md (not executed)
Options:
1. Mark complete anyway (plans weren't needed)
2. Defer work to later phase
3. Stay and finish current phase
```
Respect user judgment — they know if work matters.
**If marking complete with incomplete plans:**
- Update ROADMAP: "2/3 plans complete" (not "3/3")
- Note in transition message which plans were skipped
Transition is complete when:
- [ ] Current phase plan summaries verified (all exist or user chose to skip)
- [ ] Any stale handoffs deleted
- [ ] ROADMAP.md updated with completion status and plan count
- [ ] PROJECT.md evolved (requirements, decisions, description if needed)
- [ ] STATE.md updated (position, project reference, context, session)
- [ ] Progress table updated
- [ ] User knows next steps
