Use when working on complex multi-step tasks, when a session is getting long (40+ tool calls), when the agent starts ignoring rules it followed earlier, when conventions drift, when output quality seems to degrade, or after any context compaction event. Prevents long-session corruption AND context compaction amnesia through behavioral self-enforcement.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Session Guard ## Overview Long sessions corrupt silently. Context compaction drops instructions unannounced. Hooks don't fix it (confirmed by multiple developers on GitHub issues #19471, #9796, #64171). This skill prevents both through behavioral self-enforcement: monitor health, anchor critical rules through compaction, split before damage occurs. No packages, no databases - pure behavioral enforcement that works in every harness. ## When to Use - Session exceeds 40 tool calls - Agent contradicts earlier decisions - Style/naming conventions start drifting - After any context compaction event - Task scope growing unbounded ## Health Signals | Signal | Threshold | Action | |--------|-----------|--------| | Tool call count | >40 | YELLOW: checkpoint + recite critical rules | | Tool call count | >60 | RED: split or compact with anchor | | Agent contradicts earlier decision | Any | VERIFY: re-read source of truth | | Style/naming drift | Any | RECITE: state the active rules aloud | | File read returns unexpected content | Any | RE-READ: don't trust cached state | | Task scope growing unbounded | Continuous | SPLIT: one task per session | ## Protocol …

How to install
mdr add wshobson/agents/session-guard@sha256:2bdc028582d5a6b8The line at the top of this page pins the label git:20260707.3ea6aad, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
