nav-marker

Create a context save point that preserves conversation state so you can resume work later without re-explaining everything.

Triggers

Natural-language phrases that auto-invoke the skill:

  • “save my progress”
  • “create checkpoint”
  • “mark this point”
  • “before I take a break” / “save before lunch”
  • “risky refactor ahead” / “experiment with new approach”
  • “end of day” / “stopping for today”

What it does

  • Ensures .agent/.context-markers/ exists, then derives a marker name from your input or auto-generates marker-{YYYY-MM-DD}-{HHmm}.
  • Writes a markdown marker capturing conversation summary, docs loaded, files modified, current focus, technical decisions, and next steps.
  • Captures Theory of Mind sections: user intent and goals, stated preferences, corrections made, and belief state (what you know, assumptions made, uncertainty areas).
  • Records Loop Mode state (iteration, phase, exit signal) and Knowledge Graph state (surfaced memories, active concepts) when present.
  • Verifies the written file is non-empty, logs an md5 checksum to .agent/.marker-log, and reports the marker path and size.

Example

"Save my progress before I refactor the routing layer"

Navigator writes .agent/.context-markers/{timestamp}_before-routing-refactor.md with the full session state, verifies it, and tells you how to restore it later. Markers are git-ignored and typically 2-5k tokens.
