context-guard

A Claude Code mod in melodic-software/claude-code-plugins

Per-session context-window observability. A mod writes each session's context-window figures to a snapshot file and shows the person a toast and a transcript line when the context zone (smart, acceptable or dumb, from bands in zones.json) worsens; with model_notices on (off by default) it also tells Claude the zone at each crossing, approach and compaction. /context-guard prints status and toggles an optional band row. It answers a status tool. A PostCompact hook leaves a marker.

context-guard reaches L2 (writes or runs) by its classified calls and passed claude plugin validate on Claude Code 2.1.302.

These are the hooks and API calls reported by claude plugin validate. Access levels describe the widest reach of those calls and are not safety ratings. Validation is a static check, not a runtime test, and a passing result does not prove that a mod works or is safe. How the scan works.
