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 | $0.00034 | $0.00510 |
| Opus 5 | $0.00017 | $0.00255 |
| Sonnet 5 | $0.00007 | $0.00102 |
| Haiku 4.5 | $0.00003 | $0.00051 |
Grade A, and why
resources-and-memory-management 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 7d 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
Resource and Memory Management
1. Always Clean Up
Resources: files, connections, locks, semaphores, memory, OS handles, GPU.
Clean up in ALL paths: success, error, early return.
Language patterns: Go=defer, Rust=Drop(RAII), Python=with, TS=try/finally, Java=try-with-resources.
2. Timeout All I/O
- Network: 30s default, 5-10s interactive
- DB queries: 10s default, per-query complexity
- Files: timeout on network FS
- MQ: configurable, avoid indefinite blocking
3. Pool Expensive Resources
- DB connections: pool 5-20 per instance
- HTTP: keep-alive reuse
- Threads: CPU count (CPU-bound) or I/O wait (I/O-bound)
Pool config: min 5 (warm), max 20-50, idle timeout 5-10 min, validate before use, monitor utilization/wait/timeout.
4. Prevent Leaks
Leak = acquire + never release → exhaust system resources. Detect: monitor fd/connection/memory over time, long-duration tests, leak tools (valgrind, ASan, heap profilers). Prevent: use language cleanup patterns, never rely on manual alone.
5. Handle Backpressure
Problem: producer > consumer → unbounded queue → OOM.
Solutions: bounded queues, rate limiting, flow control, circuit breakers, drop/reject (fail fast > crash).
Memory by Language
GC'd (Go, Java, Python, JS): auto-freed, still must release non-memory resources, GC pauses in latency-sensitive, profile for retained refs.
Manual (C/C++): malloc/free, RAII in C++, prefer smart pointers.
Ownership (Rust): compiler-enforced safety, no GC, no manual mgmt. Arc/Rc for shared ownership.

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.

resources-and-memory-management is a skill published in the GitHub repository irahardianto/rugged-gemini (5 stars, last pushed 4mo ago), licensed MIT. It adds 34 tokens to every session and 510 once invoked, about $0.0002 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 2026-09-03.
