Dev Session

What it does

The Dev Session skill helps manage and structure development work across multiple sessions, particularly for complex features or projects where context limitations might be a concern. It generates SESSION.md files that act as persistent records of progress, allowing developers to easily resume work later and handoff tasks cleanly. The skill supports starting new sessions, creating checkpoints at key milestones, resuming previous sessions, and wrapping up completed phases.

When to use it

• Multi-phase feature development: When working on a feature that spans multiple coding sessions.
• Potential context compaction issues: If you anticipate your work might exceed the AI agent's context window.
• Before risky changes: To create a checkpoint before making potentially destructive code modifications.

Key capabilities

• Session Management: Starts, resumes, and wraps development sessions.
• Checkpointing: Creates checkpoints with commit hashes and detailed progress information.
• Persistent Progress Tracking: Stores session details in SESSION.md files that survive context limitations.
• Contextual Resumption: Provides a summary of the last known state (phase, position, changes, blockers, next steps) when resuming a session.
• Learning Capture: Adds key learnings and commands to a project's CLAUDE.md file for future reference.
• Git Integration: Automatically performs Git add and commit operations during checkpointing.

Example prompts

• "start session"
• "checkpoint"
• "resume"
• "wrap session"

Tips & gotchas

• The skill relies on a CLAUDE.md file in the project root for initial context and learning capture.
• SESSION.md files are created in the project root, so be mindful of their presence.
• Ensure your Resume Instructions within SESSION.md are clear and actionable for future sessions.
