name: log-to-project description: Log work activity to a specific project folder. Maintains changelogs, session notes, and decision records for projects. use_when: User asks to log activity to a project, update project documentation, capture session outcomes, or record changes to a project.

Log to Project

Capture project-specific activity to the project folder, maintaining history and context for ongoing work.

Why This Matters

Projects without documentation become black boxes. With project logging:

• You can resume work after weeks away
• Decisions have recorded rationale
• Progress is visible and trackable
• Future sessions have full context

Configuration

Add to your CLAUDE.md:

Copy## Vault Configuration
Projects location: 02 Projects/
Code repositories: ~/Dev/

Project Folder Structure

Copy02 Projects/[Project Name]/
├── PROJECT.md                    # Canonical status file
├── CHANGELOG.md                  # Version history

Quick Start

1. Identify project(s) worked on
2. Find or create project folder in 02 Projects/
3. Update CHANGELOG.md with changes
4. Create session log if substantial work
5. Create decision record if architectural choices made

Process

Step 1: Identify the project

• Match work to existing project in 02 Projects/
• Or identify code repo in development folder
• If new project, use /start-project first

Step 2: Ensure structure exists

• Create Sessions/ and Decisions/ folders if needed
• Verify PROJECT.md exists

Step 3: Analyze session content

Identify:

• Features added or modified
• Bugs fixed
• Architectural decisions
• Configuration changes
• Files modified
• Next steps

Step 4: Update CHANGELOG.md

• Add entries under [Unreleased]
• Categorize as Added, Changed, Fixed, or Removed
• Be specific: "Add user authentication" not "Updates"

Step 5: Create session log (for substantial work)

• Create Sessions/session-YYYYMMDD.md
• Include summary, changes, decisions, next steps

Step 6: Create decision record (for significant decisions)

• Create Decisions/decision-YYYYMMDD-topic.md
• Document context, decision, and consequences

Good entries:

• "Add password reset flow with email verification"
• "Fix calculation error in monthly totals"
