Chipoto69 Claude Skills Devlog Harvester

DevLog Harvester

Captures development session data through smart, non-intrusive triggers.

Trigger Mechanisms

1. Git Commit Hook (Primary)

Every commit triggers a mini-harvest capturing:

• Files changed in commit
• Commit message (intent)
• Session context at commit time

2. Time-Based Rollups (3x Daily)

Scheduled at: 9:00, 14:00, 21:00

• Aggregates accumulated data
• Writes to Obsidian via knowledge-forge

3. Project Switch Detection

When changing project directories:

• Flush current project's accumulated data
• Initialize harvester for new project

4. Idle Flush (30 min)

After 30 minutes of no tool calls:

• Flush accumulated session data
• Prevents data loss

Data Captured

Per-Session Data

session:
  project: ATLAS-main
  started: 2026-01-19T09:15:00
  ended: 2026-01-19T12:30:00
  duration_minutes: 195
  
files_touched:
  - path: src/api/client.py
    operations: [read, edit, read]
    lines_changed: +45/-12
    
  - path: tests/test_api.py
    operations: [create, edit]
    lines_changed: +120/-0

git_activity:
  commits: 3
  messages:
    - "feat(api): add chat endpoint"
    - "test: add API client tests"
    - "fix: handle timeout errors"
  total_insertions: 165
  total_deletions: 12

errors_encountered:
  - type: "ImportError"
    file: "src/api/client.py"
    resolution: "Added missing httpx dependency"

decisions_made:
  - "Used httpx instead of requests for async support"
  - "Added retry logic with exponential backoff"

Usage

Manual Harvest

# Harvest current session
/harvest

# Harvest specific project
/harvest --project ATLAS-main

# Harvest and immediately write to Obsidian
/harvest --write

Automatic (via hooks)

The harvester runs automatically when:

• You make a git commit
• You switch projects (cd to different repo)
• 3x daily at scheduled times
• After 30 minutes of inactivity

Integration Points

Input Sources

• Git history (git log, git diff)
• Session transcripts (~/.claude/transcripts/)
• Tool usage (from session context)
• AGI-memory recalls

Output Destinations

• → knowledge-forge (for synthesis)
• → obsidian-bridge (for storage)
• → Local cache (~/.cache/devlog/)

Configuration

Set in ~/.config/devlog/config.yaml:

harvester:
  # Rollup times (24h format)
  rollup_times: ["09:00", "14:00", "21:00"]
  
  # Idle threshold before flush (minutes)
  idle_threshold: 30
  
  # Cache directory
  cache_dir: ~/.cache/devlog
  
  # Projects to track (empty = all)
  tracked_projects: []
  
  # Projects to ignore
  ignored_projects:
    - node_modules
    - .git
