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 | $0.00045 | $0.00568 |
| Opus 5 | $0.00023 | $0.00284 |
| Sonnet 5 | $0.00009 | $0.00114 |
| Haiku 4.5 | $0.00005 | $0.00057 |
Grade A, and why
memory-safety-patterns 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 4d 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.

Memory Safety Patterns
Cross-language patterns for memory-safe programming including RAII, ownership, smart pointers, and resource management.
When to Use This Skill
- Writing memory-safe systems code
- Managing resources (files, sockets, memory)
- Preventing use-after-free and leaks
- Implementing RAII patterns
- Choosing between languages for safety
- Debugging memory issues
Core Concepts
1. Memory Bug Categories
| Bug Type | Description | Prevention |
|---|---|---|
| Use-after-free | Access freed memory | Ownership, RAII |
| Double-free | Free same memory twice | Smart pointers |
| Memory leak | Never free memory | RAII, GC |
| Buffer overflow | Write past buffer end | Bounds checking |
| Dangling pointer | Pointer to freed memory | Lifetime tracking |
| Data race | Concurrent unsynchronized access | Ownership, Sync |
2. Safety Spectrum
Manual (C) → Smart Pointers (C++) → Ownership (Rust) → GC (Go, Java)
Less safe More safe
More control Less control

Best Practices
Do's
- Prefer RAII - Tie resource lifetime to scope
- Use smart pointers - Avoid raw pointers in C++
- Understand ownership - Know who owns what
- Check bounds - Use safe access methods
- Use tools - AddressSanitizer, Valgrind, Miri
Don'ts
- Don't use raw pointers - Unless interfacing with C
- Don't return local references - Dangling pointer
- Don't ignore compiler warnings - They catch bugs
- Don't use
unsafecarelessly - In Rust, minimize it - Don't assume thread safety - Be explicit
What ships with it
1 file 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-safety-patterns is a skill published in the GitHub repository RudyCity/superagent (21 stars, last pushed today), licensed MIT. It adds 45 tokens to every session and 568 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.
