Complete Milestone

/meridian:complete-milestone — Complete Milestone

Audit readiness, mark the milestone complete, create a git tag, persist a summary, and optionally archive.

Prerequisites

• MERIDIAN_HOME set to the repo root (default: current directory)
• uv installed with project dependencies synced
• Clean or committed working tree (for git tag)

Arguments

• --archive — Also archive after completion
• --no-uat — Skip UAT debt check in audit
• --no-stubs — Skip stub detection in audit
• --force — Complete even if UAT/stub issues exist (phase/plan checks still enforced)

Keywords

complete, milestone, finish, archive, git tag, ship

Procedure

Step 1: Identify active milestone

MERIDIAN_HOME="${MERIDIAN_HOME:-.}"
PYTHONPATH="$MERIDIAN_HOME" uv run --project "$MERIDIAN_HOME" python -c "
import json
from scripts.db import connect, get_db_path
from scripts.state import get_status
conn = connect(get_db_path('.'))
status = get_status(conn)
ms = status.get('active_milestone')
if not ms:
    print('ERROR: no active milestone')
else:
    print(json.dumps({'id': ms['id'], 'name': ms['name']}, indent=2))
conn.close()
"

Save the milestone id as MILESTONE_ID and name as MILESTONE_NAME.

Step 2: Run audit

Run /meridian:audit-milestone first and confirm ready is true.

For --force mode, set check_uat=False, check_stubs=False in Step 3.

Step 3: Complete the milestone

PYTHONPATH="$MERIDIAN_HOME" uv run --project "$MERIDIAN_HOME" python -c "
import json
from pathlib import Path
from scripts.db import connect, get_db_path
from scripts.milestone_lifecycle import complete_milestone
conn = connect(get_db_path('.'))
result = complete_milestone(
    conn,
    '$MILESTONE_ID',
    repo_path=Path('.'),
    planning_dir=Path('.planning'),
    check_uat=True,
    check_stubs=True,
    persist_summary=True,
)
print(json.dumps(result, indent=2, default=str))
conn.close()
"

Save result['git_tag'] as GIT_TAG and result['summary_path'] as SUMMARY_PATH.

Step 4: Create git tag

git tag -a "$GIT_TAG" -m "Milestone $MILESTONE_ID ($MILESTONE_NAME) completed"

Verify: git tag -l "milestone/*"

Step 5: Display summary

cat "$SUMMARY_PATH"

Or generate on demand:

PYTHONPATH="$MERIDIAN_HOME" uv run --project "$MERIDIAN_HOME" python -c "
from scripts.db import connect, get_db_path
from scripts.milestone_lifecycle import generate_milestone_summary
conn = connect(get_db_path('.'))
print(generate_milestone_summary(conn, '$MILESTONE_ID'))
conn.close()
"

Step 6 (optional): Archive

If --archive was requested:

PYTHONPATH="$MERIDIAN_HOME" uv run --project "$MERIDIAN_HOME" python -c "
import json
from scripts.db import connect, get_db_path
from scripts.milestone_lifecycle import archive_milestone
conn = connect(get_db_path('.'))
result = archive_milestone(conn, '$MILESTONE_ID')
print(json.dumps(result, indent=2))
conn.close()
"

Output Format

# Milestone Complete — {milestone_name}

Status: complete
Git tag: milestone/{id}
Summary: .planning/milestones/{id}-SUMMARY.md

## Stats
  Phases:   {n}
  Plans:    {n}
  Duration: {n} days

→ Run: git push origin milestone/{id}
→ Start next milestone with /meridian:roadmap

Error Handling

| Error | Cause | Fix | |-------|-------|-----| | not ready for completion | Incomplete phases or failed plans | Resolve issues from audit | | Milestone not found | Wrong milestone ID | Check active milestone in Step 1 | | git tag already exists | Tag was created before | Delete with git tag -d $GIT_TAG then retry |

Notes for non-Claude LLMs

• All bash blocks are self-contained; substitute $MILESTONE_ID / $GIT_TAG with actual values
• Steps 2-6 depend on the id from Step 1 — execute sequentially
• check_uat=False, check_stubs=False disables optional checks (equivalent to --force)
• If the milestone has no completed_at after Step 3, the transition failed — check DB state
