# Session Guard

For when the agent quietly stops following the rules you set

## What this does

In a long working session an agent can start ignoring instructions it was following fine an hour ago, and conventions slowly slip. This is a check against that, including after context gets compacted and things drop out of memory. Reach for it on long multi-step tasks, or the moment you notice the quality sliding.

### Top 3 things it does for you

- Keep an agent on the rules it agreed to earlier in a long session
- Recover after context was compacted and things were forgotten
- Steady output that's been drifting over a long task

A scan is named by the exact content it read, not by a version number. A different version is a different artifact, and nothing here applies to a version AIR has not scanned.

## About Session Guard

Long sessions decay. Rules that were followed early get ignored, conventions drift, and output quality slips - often without anything announcing it. Context compaction adds its own kind of forgetting.

This works against both, through behavioral self-enforcement. Use it during complex multi-step tasks, once a session has run long, when the agent starts ignoring earlier rules, or after any context compaction event.

## Questions

### Is Session Guard safe to install?

AIR scanned this exact version of Session Guard and flagged nothing. AIR's verdict: safe. The verdict is named by the content that was read, at commit b6af37110581, so it cannot drift onto a version nobody scanned. The full report is at https://airmarket.ai/security/session-guard.

### How do I install Session Guard?

Open https://airmarket.ai/app/session-guard on Air Market and use the install action: Air Market hands Claude a prompt naming this exact skill, and Claude sets it up. Source, pinned to the exact commit this listing describes: https://github.com/wshobson/agents/tree/b6af3711058190e4b5c5274b9758498fe626ec5a/plugins/skill-forge-essentials/skills/session-guard.
