Compare agent skills before installing.

Write the current session's in-flight work state to a human-readable handoff doc on disk (docs/context/CONTEXT-{topic}.md) so a future chat session — or another person — can pick up exactly where this one stops. Distinct from Claude Code's built-in memory system, which captures long-lived facts and preferences; this skill captures **active session context** (what's being built right now, which files are mid-edit, what's been tried, what's next). Use when the user says "save context", "checkpoint", "save progress", "preserve state", "save before I step away", "dump this so I can continue tomorrow", or before ending a long session with incomplete work. Optimizes for correctness, completeness, minimal size, and trajectory preservation.

Implement work from an approved spec or ticket set, run focused and full tests, invoke code review, and commit the result to the current branch.
