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 | $0.00074 | $0.01087 |
| Opus 5 | $0.00037 | $0.00544 |
| Sonnet 5 | $0.00015 | $0.00217 |
| Haiku 4.5 | $0.00007 | $0.00109 |
Grade A, and why
m02-resource 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 9d 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.

Resource Management
Layer 1: Language Mechanics
Core Question
What ownership pattern does this resource need?
Before choosing a smart pointer, understand:
- Is ownership single or shared?
- Is access single-threaded or multi-threaded?
- Are there potential cycles?
Error → Design Question
| Error | Don't Just Say | Ask Instead |
|---|---|---|
| "Need heap allocation" | "Use Box" | Why can't this be on stack? |
| Rc memory leak | "Use Weak" | Is the cycle necessary in design? |
| RefCell panic | "Use try_borrow" | Is runtime check the right approach? |
| Arc overhead complaint | "Accept it" | Is multi-thread access actually needed? |
Thinking Prompt
Before choosing a smart pointer:
-
What's the ownership model?
- Single owner → Box or owned value
- Shared ownership → Rc/Arc
- Weak reference → Weak
-
What's the thread context?
- Single-thread → Rc, Cell, RefCell
- Multi-thread → Arc, Mutex, RwLock
-
Are there cycles?
- Yes → One direction must be Weak
- No → Regular Rc/Arc is fine
Trace Up ↑
When pointer choice is unclear, trace to design:
"Should I use Arc or Rc?"
↑ Ask: Is this data shared across threads?
↑ Check: m07-concurrency (thread model)
↑ Check: domain-* (performance constraints)
| Situation | Trace To | Question |
|---|---|---|
| Rc vs Arc confusion | m07-concurrency | What's the concurrency model? |
| RefCell panics | m03-mutability | Is interior mutability right here? |
| Memory leaks | m12-lifecycle | Where should cleanup happen? |
Trace Down ↓
From design to implementation:
"Need single-owner heap data"
↓ Use: Box<T>
"Need shared immutable data (single-thread)"
↓ Use: Rc<T>
"Need shared immutable data (multi-thread)"
↓ Use: Arc<T>
"Need to break reference cycle"
↓ Use: Weak<T>
"Need shared mutable data"
↓ Single-thread: Rc<RefCell<T>>
↓ Multi-thread: Arc<Mutex<T>> or Arc<RwLock<T>>
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.

m02-resource is a skill published in the GitHub repository moeru-ai/auv (27 stars, last pushed yesterday), licensed Apache-2.0. It adds 74 tokens to every session and 1,087 once invoked, about $0.0004 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.
