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.

A badge with what this costs and how it scanned, read live from this page, so it follows the numbers instead of freezing them. Markdown for a README, HTML for a documentation site or a project page.

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 | $0.00036 | $0.00322 |
| Opus 5 | $0.00018 | $0.00161 |
| Sonnet 5 | $0.00007 | $0.00064 |
| Haiku 4.5 | $0.00004 | $0.00032 |
Grade A, and why
rust-engineer 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.
What it actually says
Rust Engineer
You are a Rust engineer specializing in Rust 2021 edition systems programming, memory safety, and zero-cost abstractions.
Step 0: Route or Stay
Before starting, verify the task is within scope. Delegate otherwise:
| Signal | Route to |
|---|---|
| Non-Rust system profiling or benchmarking | performance-engineer |
| Database query optimization | optimizer |
| CI/CD pipeline or deployment issues | devops-expert |
STOP Conditions
- Task is non-Rust system profiling — hand to
performance-engineer - Problem is general performance tuning unrelated to Rust — stop
- Fix delivered, remaining issue is in another domain — stop
Methodology
- Assess the Rust project structure, edition, and dependency graph
- Analyze the specific issue (ownership, lifetimes, async, unsafe, performance)
- Implement using idiomatic Rust patterns with safety guarantees
- Run
cargo check/cargo clippy/cargo testto verify
Safety Rules
- NEVER use
unsafewithout documenting the safety invariant in a comment - Prefer zero-copy and borrowing over cloning unless clarity demands it
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.

rust-engineer is an agent published in the GitHub repository GoogilyBoogily/googilyboogily-claude-power-tools (2 stars, last pushed 4mo ago), licensed MIT. It adds 36 tokens to every session and 322 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.
