Remove an unstarted future phase from the roadmap and renumber all subsequent phases to maintain a clean, linear sequence.
Purpose: Clean removal of work you've decided not to do, without polluting context with cancelled/deferred markers.
Output: Phase deleted, all subsequent phases renumbered, git commit as historical record.

<step name="parse_arguments">
Parse the command arguments:
- Argument is the phase number to remove (integer or decimal)
- Example: `/kata-remove-phase 17` → phase = 17
- Example: `/kata-remove-phase 16.1` → phase = 16.1
If no argument provided:
ERROR: Phase number required
Usage: /kata-remove-phase <phase-number>
Example: /kata-remove-phase 17
Exit.
</step>
<step name="load_state">
Load project state:
bash
cat .planning/STATE.md 2>/dev/null
cat .planning/ROADMAP.md 2>/dev/null
Parse current phase number from STATE.md "Current Position" section.
</step>
<step name="validate_phase_exists">
Verify the target phase exists in ROADMAP.md:
-
-
If not found:
ERROR: Phase {target} not found in roadmap
Available phases: [list phase numbers]
Exit.
</step>
<step name="validate_future_phase">
Verify the phase is a future phase (not started):
- Compare target phase to current phase from STATE.md
- Target must be > current phase number
If target <= current phase:
ERROR: Cannot remove Phase {target}
Only future phases can be removed:
- Current phase: {current}
- Phase {target} is current or completed
To abandon current work, use /kata-pause-work instead.
Exit.
- Find and check for SUMMARY.md files in phase directory:
bash
# Universal phase discovery for target phase
PADDED_TARGET=$(printf "%02d" "$TARGET" 2>/dev/null || echo "$TARGET")
PHASE_DIR=""
for state in active pending completed; do
PHASE_DIR=$(find .planning/phases/${state} -maxdepth 1 -type d -name "${PADDED_TARGET}-*" 2>/dev/null | head -1)
[ -z "$PHASE_DIR" ] && PHASE_DIR=$(find .planning/phases/${state} -maxdepth 1 -type d -name "${TARGET}-*" 2>/dev/null | head -1)
[ -n "$PHASE_DIR" ] && break
done
# Fallback: flat directory (backward compatibility)
if [ -z "$PHASE_DIR" ]; then
PHASE_DIR=$(find .planning/phases -maxdepth 1 -type d -name "${PADDED_TARGET}-*" 2>/dev/null | head -1)
[ -z "$PHASE_DIR" ] && PHASE_DIR=$(find .planning/phases -maxdepth 1 -type d -name "${TARGET}-*" 2>/dev/null | head -1)
fi
find "${PHASE_DIR}" -maxdepth 1 -name "*-SUMMARY.md" 2>/dev/null
If any SUMMARY.md files exist:
ERROR: Phase {target} has completed work
Found executed plans:
- {list of SUMMARY.md files}
Cannot remove phases with completed work.
Exit.
</step>
<step name="gather_phase_info">
Collect information about the phase being removed:
- Extract phase name from ROADMAP.md heading:
### Phase {target}: {Name}
- Phase directory already found via universal discovery:
- Find all subsequent phases (searching across active/pending/completed subdirectories) (integer and decimal) that need renumbering
Subsequent phase detection:
For integer phase removal (e.g., 17):
- Find all phases > 17 (integers: 18, 19, 20...)
- Find all decimal phases >= 17.0 and < 18.0 (17.1, 17.2...) → these become 16.x
- Find all decimal phases for subsequent integers (18.1, 19.1...) → renumber with their parent
For decimal phase removal (e.g., 17.1):
- Find all decimal phases > 17.1 and < 18 (17.2, 17.3...) → renumber down
- Integer phases unchanged
List all phases that will be renumbered.
</step>
<step name="confirm_removal">
Present removal summary and confirm:
Removing Phase {target}: {Name}
This will:
- Delete: ${PHASE_DIR}
- Renumber {N} subsequent phases:
- Phase 18 → Phase 17
- Phase 18.1 → Phase 17.1
- Phase 19 → Phase 18
[etc.]
Proceed? (y/n)
Wait for confirmation.
</step>
<step name="delete_phase_directory">
Delete the target phase directory if it exists:
bash
if [ -d "${PHASE_DIR}" ]; then
rm -rf "${PHASE_DIR}"
echo "Deleted: ${PHASE_DIR}"
fi
If directory doesn't exist, note: "No directory to delete (phase not yet created)"
</step>
<step name="renumber_directories">
Rename all subsequent phase directories:
For each phase directory that needs renumbering (in reverse order to avoid conflicts):
Find each subsequent phase using universal discovery, then rename within the same state subdirectory:
bash
# For each subsequent phase, find it across state subdirectories
for state in active pending completed; do
# Example: renaming 18-dashboard to 17-dashboard within the same state dir
SRC=$(find .planning/phases/${state} -maxdepth 1 -type d -name "18-dashboard" 2>/dev/null | head -1)
[ -n "$SRC" ] && mv "$SRC" ".planning/phases/${state}/17-dashboard"
done
# Fallback: flat directory
SRC=$(find .planning/phases -maxdepth 1 -type d -name "18-dashboard" 2>/dev/null | head -1)
[ -n "$SRC" ] && mv "$SRC" ".planning/phases/17-dashboard"
Process in descending order (20→19, then 19→18, then 18→17) to avoid overwriting.
Also rename decimal phase directories:
- → (if removing integer 17)
- → (if removing decimal 17.1)
</step>
<step name="rename_files_in_directories">
Rename plan files inside renumbered directories:
For each renumbered directory, rename files that contain the phase number:
bash
# Inside 17-dashboard (was 18-dashboard):
mv "18-01-PLAN.md" "17-01-PLAN.md"
mv "18-02-PLAN.md" "17-02-PLAN.md"
mv "18-01-SUMMARY.md" "17-01-SUMMARY.md" # if exists
# etc.
Also handle CONTEXT.md and DISCOVERY.md (these don't have phase prefixes, so no rename needed).
</step>
<step name="update_roadmap">
Update ROADMAP.md:
-
Remove the phase section entirely:
- Delete from to the next phase heading (or section end)
-
Remove from phase list:
- Delete line
- [ ] **Phase {target}: {Name}**
or similar
-
Remove from Progress table:
- Delete the row for Phase {target}
-
Renumber all subsequent phases:
- →
- →
- Table rows: →
- Plan references: →
-
Update dependency references:
- →
- For the phase that depended on the removed phase:
-
Renumber decimal phases:
- → (if integer 17 removed)
- Update all references consistently
Write updated ROADMAP.md.
</step>
<step name="update_state">
Update STATE.md:
-
Update total phase count:
-
Recalculate progress percentage:
- New percentage based on completed plans / new total plans
Do NOT add a "Roadmap Evolution" note - the git commit is the record.
Write updated STATE.md.
</step>
<step name="update_file_contents">
Search for and update phase references inside plan files:
bash
# Find files that reference the old phase numbers (search across state subdirectories)
for state in active pending completed; do
grep -r "Phase 18" .planning/phases/${state}/17-*/ 2>/dev/null
grep -r "Phase 19" .planning/phases/${state}/18-*/ 2>/dev/null
done
# Fallback: flat directories
grep -r "Phase 18" .planning/phases/17-*/ 2>/dev/null
grep -r "Phase 19" .planning/phases/18-*/ 2>/dev/null
# etc.
Update any internal references to reflect new numbering.
</step>
<step name="commit">
Stage and commit the removal:
Check planning config:
bash
COMMIT_PLANNING_DOCS=$(cat .planning/config.json 2>/dev/null | grep -o '"commit_docs"[[:space:]]*:[[:space:]]*[^,}]*' | grep -o 'true\|false' || echo "true")
git check-ignore -q .planning 2>/dev/null && COMMIT_PLANNING_DOCS=false
If COMMIT_PLANNING_DOCS=false
: Skip git operations
If COMMIT_PLANNING_DOCS=true
(default):
bash
git add .planning/
git commit -m "chore: remove phase {target} ({original-phase-name})"
The commit message preserves the historical record of what was removed.

<anti_patterns>
- Don't remove completed phases (have SUMMARY.md files)
- Don't remove current or past phases
- Don't leave gaps in numbering - always renumber
- Don't add "removed phase" notes to STATE.md - git commit is the record
- Don't ask about each decimal phase - just renumber them
- Don't modify completed phase directories
</anti_patterns>
<edge_cases>
Removing a decimal phase (e.g., 17.1):
- Only affects other decimals in same series (17.2 → 17.1, 17.3 → 17.2)
- Integer phases unchanged
- Simpler operation
No subsequent phases to renumber:
- Removing the last phase (e.g., Phase 20 when that's the end)
- Just delete and update ROADMAP.md, no renumbering needed
Phase directory doesn't exist:
- Phase may be in ROADMAP.md but directory not created yet
- Skip directory deletion, proceed with ROADMAP.md updates
Decimal phases under removed integer:
- Removing Phase 17 when 17.1, 17.2 exist
- 17.1 → 16.1, 17.2 → 16.2
- They maintain their position in execution order (after current last integer)
</edge_cases>
<success_criteria>
Phase removal is complete when:
