What it costs to keep this loaded
Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00016 | $0.00734 |
| Opus 5 | $0.00008 | $0.00367 |
| Sonnet 5 | $0.00003 | $0.00147 |
| Haiku 4.5 | $0.00002 | $0.00073 |
Grade A, and why
context-health-monitor scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 13d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
How it starts
The opening of the file, as written. The whole thing — 106 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Context Health Monitor
Purpose
Prevent "Context Rot" — the quality degradation that occurs as the agent processes more information in a single session.
When This Skill Activates
The agent should self-monitor for these warning signs:
Warning Signs
| Signal | Threshold | Action |
|---|---|---|
| Repeated debugging | 3+ failed attempts | Trigger state dump |
| Going in circles | Same approach tried twice | Stop and reassess |
| Confusion indicators | "I'm not sure", backtracking | Document uncertainty |
| Session length | Extended back-and-forth | Recommend /pause |
Behavior Rules
Rule 1: The 3-Strike Rule
If debugging the same issue fails 3 times:
- STOP attempting fixes
- Document in
.gsd/STATE.md:- What was tried
- What errors occurred
- Current hypothesis
- Recommend user start fresh session
- Do NOT continue with more attempts
Rule 2: Circular Detection
If the same approach is being tried again:
- Acknowledge the repetition
- List what has already been tried
- Propose a fundamentally different approach
- Or recommend
/pausefor fresh perspective
Rule 3: Uncertainty Logging
When uncertain about an approach:
- State the uncertainty clearly
- Document in
.gsd/DECISIONS.md:- The uncertain decision
- Why it's uncertain
- Alternatives considered
- Ask user for guidance rather than guessing
State Dump Format
When triggered, write to .gsd/STATE.md:
## Context Health: State Dump
**Triggered**: [date/time]
**Reason**: [3 failures / circular / uncertainty]
### What Was Attempted
1. [Approach 1] — Result: [outcome]
2. [Approach 2] — Result: [outcome]
3. [Approach 3] — Result: [outcome]
### Current Hypothesis
[Best guess at root cause]
### Recommended Next Steps
1. [Fresh perspective action]
2. [Alternative approach to try]
### Files Involved
- [file1.ext] — [what state it's in]
- [file2.ext] — [what state it's in]
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

context-health-monitor is a skill published in the GitHub repository toonight/get-shit-done-for-antigravity (947 stars, last pushed 22d ago), licensed MIT. It adds 16 tokens to every session and 734 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
