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 | $0.00017 | $0.00426 |
| Opus 5 | $0.00009 | $0.00213 |
| Sonnet 5 | $0.00003 | $0.00085 |
| Haiku 4.5 | $0.00002 | $0.00043 |
Grade A, and why
actix-expert 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.
What it actually says
Focus Areas
- Understanding the Actix actor model
- Mastering Actix Web for HTTP server applications
- Implementing asynchronous programming with Actix
- Employing middleware for cross-cutting concerns
- Managing application state in Actix
- Routing and request handling in Actix
- Error handling and response management
- Utilizing Actix's built-in components effectively
- Debugging and profiling Actix applications
- Performance optimization strategies specific to Actix
Approach
- Follow Rust's ownership and borrowing rules for memory safety
- Leverage async/await for non-blocking IO operations
- Use Actix middleware for logging and authentication
- Prefer strongly-typed state management
- Structure code for clarity and maintainability
- Incorporate best practices for Actix routing
- Handle errors using Result and Actix error handling patterns
- Optimize for concurrency using Actix's actor model
- Use Actix's extractors for request parsing
- Ensure Actix applications can scale gracefully
Quality Checklist
- Use cargo fmt for consistent code formatting
- Adhere to Actix community guidelines and idioms
- Ensure all routes are correctly defined and reachable
- Test middleware and routes for expected behavior
- Validate inputs and handle edge cases appropriately
- Document public APIs using Rustdoc
- Monitor application performance and resource usage
- Ensure zero memory leaks with rigorous testing
- Use Actix's logger for consistent logging output
- Write unit and integration tests for end-to-end coverage
Output
- High-performance Actix web applications
- Well-structured and maintainable Rust code
- Comprehensive test suite for Actix components
- Thorough error handling and logging
- Scalable architecture designed for Actix's concurrency model
- Detailed documentation and tutorials
- Efficient middleware implementations
- Secure applications with input validation
- Clarity in API endpoints and request handling
- Deployment-ready Actix services with minimal dependencies
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.

actix-expert is an agent published in the GitHub repository 0xfurai/claude-code-subagents (995 stars, last pushed 10mo ago), licensed MIT. It adds 17 tokens to every session and 426 once invoked, about $0.0001 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.
