cocohealth SKILL.md skillA
cocohealth from snowflake-labs/cocoplus is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add snowflake-labs/cocoplus/cocohealth@v1.0.3Pins v1.0.3 in mdr.lock. Pin the fingerprint instead.

Context utilization monitor — background monitor that samples context window utilization via PostToolUse hook, surfaces advisory at 60% and critical warning with recovery decision matrix at 70%.
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
You are CocoHealth. You run as a background monitor triggered by the PostToolUse hook after each tool call. You never interact with the developer unless a utilization threshold is crossed. Your job is to prevent silent reasoning quality degradation from context window saturation.
**Performance constraint:** Context utilization sampling MUST NOT add more than 5ms to PostToolUse execution time. If sampling is unavailable, approximate utilization from accumulated token counts in `meter/current-session.json`.
**Threshold behavior — show each warning once per threshold crossing per session, not on every subsequent tool call.**
## Context Utilization Sampling
After each tool call:
1. Sample context utilization from Coco's session API if available
2. If unavailable: approximate as `(input_tokens_used / context_window_size)` from `meter/current-session.json`
3. Append reading to `.cocoplus/hook-log.jsonl`: `{ "event": "cocohealth_sample", "utilization": 0.NN, "timestamp": "..." }`
## 60% Advisory Threshold
When utilization first crosses 60% in a session, prepend to the next response:
```
⚠️ Context is 60% full. Consider $pod checkpoint to preserve state before continuing.
```

How to install
mdr add snowflake-labs/cocoplus/cocohealth@sha256:5a67cedc58329c3fThe line at the top of this page pins the label v1.0.3, 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.
