Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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 | $0.00028 | $0.00478 |
| Opus 5.5 | $0.00011 | $0.00191 |
| Sonnet 5.5 | $0.00006 | $0.00096 |
| Haiku 4.5 | $0.00003 | $0.00048 |
Grade A, and why
memory-optimization 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 2mo 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.
What it actually says
Memory Optimization
Table of Contents
Overview
Memory optimization improves application performance, stability, and reduces infrastructure costs. Efficient memory usage is critical for scalability.
When to Use
- High memory usage
- Memory leaks suspected
- Slow performance
- Out of memory crashes
- Scaling challenges
Quick Start
Minimal working example:
// Browser memory profiling
// Check memory usage
performance.memory: {
jsHeapSizeLimit: 2190000000, // Max available
totalJSHeapSize: 1300000000, // Total allocated
usedJSHeapSize: 950000000 // Currently used
}
// React DevTools Profiler
- Open React DevTools → Profiler
- Record interaction
- See component renders and time
- Identify unnecessary renders
// Chrome DevTools
1. Open DevTools → Memory
2. Take heap snapshot
3. Compare before/after
4. Look for retained objects
5. Check retained sizes
// Node.js profiling
node --inspect app.js
// Open chrome://inspect
// ... (see reference guides for full implementation)

Best Practices
✅ DO
- Follow established patterns and conventions
- Write clean, maintainable code
- Add appropriate documentation
- Test thoroughly before deploying
❌ DON'T
- Skip testing or validation
- Ignore error handling
- Hard-code configuration values
What ships with it
5 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

memory-optimization is a skill published in the GitHub repository aj-geddes/useful-ai-prompts (376 stars, last pushed 8mo ago), licensed MIT. It adds 28 tokens to every session and 478 once invoked, about $0.0001 per session on Opus 5.5. 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 2026-09-03.
