## Next Steps

Continue execution from task ${n}

// Try plan filename first
const planFiles = glob('docs/plans/YYYY-MM-DD-*.md')
if (planFiles.length > 0) {
  // Extract from: docs/plans/2025-11-20-user-auth.md → user-auth
  featureName = planFiles[0].match(/\d{4}-\d{2}-\d{2}-(.+)\.md$/)[1]
}

// Fall back to brainstorm topic
if (!featureName) {
  // Extract from conversation history
  featureName = extractFromBrainstormTopic()
}

// Ask user if ambiguous
if (!featureName) {
  featureName = await askUser("Feature name for save file?")
}

# Git commit hash
git rev-parse HEAD

# Current branch
git branch --show-current

# ISO timestamp
date -Iseconds

# Git status for changes
git status --short

Save checkpoint as:
A) Research (brainstorm + research complete, no plan yet)
B) Planning (plan in progress)
C) Execution (currently implementing tasks)
D) Complete (all tasks finished)

Current stage? (A/B/C/D)

await mcp__serena__write_memory({
  memory_file_name: `${date}-${feature}-${stage}.md`,
  content: `---\n${frontmatter}\n---\n\n${content}`
})

Checkpoint saved: ${filename}

Stage: ${stage}
