# HarnessLink 17.5.62 release notes

3 changes, released Oct 9, 2026.

### Added

- Context monitor in local gateway (`gateway/context-monitor.ts`): evaluates prompt tokens against model context windows and emits `x-superpi-recommend-clear` and utilization headers when reaching the 10% context ceiling, preventing expensive LLM context compaction while preserving prefix cache hits.
- Instruction Decomposition Engine and `hnl tasks` command (`tasks/decomposer.ts`, `commands/tasks.ts`): tears apart complex or gabbled prompts into atomic requirements organized across 5 disciplined execution phases (Investigation, Implementation, Verification, Auto-Verification, Validation & Use).
- Zero-loss session clear recovery: `assembleBrief` automatically injects active work-state snapshots (`state/<harness>--<sessionId>.md`) on `SessionStart`, restoring plans and progress immediately following a `/clear` reset.
