Session Sync

What it does

Session Sync provides a one-command checkpoint workflow that appends structured summaries to session-context files and updates MEMORY.md. It is focused on speed and minimal interruption: the skill edits the active context, decisions, patterns, and troubleshooting files, and optionally runs a capability inventory when invoked with the full flag. The result is a concise session snapshot you can review later.

When to use it

Use this skill whenever the agent or user wants a fast, deterministic save of session state — e.g., before switching tasks, handing off the session, or taking a break. Invoke with /sync for a lightweight checkpoint or /sync --full to regenerate the capability inventory and capture tool/test coverage metadata.

What's included

• Scripts: none embedded, but the skill defines clear file-editing steps to update session-context/* and MEMORY.md.
• References: none bundled.
• Instructions: procedural steps to append a timestamped "SYNC" section to CLAUDE-activeContext.md, CLAUDE-decisions.md, CLAUDE-patterns.md, and CLAUDE-troubleshooting.md, plus guidance for capability inventory generation when --full is used.

Compatible agents

This skill is suitable for agents with file access in the main session (Claude-style assistants or similar) that can perform local file edits and run local tooling. It intentionally avoids spawning subagents or external MCP tools.
