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.

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 | $0.00078 | $0.00777 |
| Opus 5 | $0.00039 | $0.00388 |
| Sonnet 5 | $0.00016 | $0.00155 |
| Haiku 4.5 | $0.00008 | $0.00078 |
Grade A, and why
rust-network-module 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 2d 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.
How it starts
The opening of the file, as written. The whole thing — 73 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Rust Network Module Scaffolding
Scaffold new async networking modules following nat464-sidecar's established patterns.
Workflow
1. Determine Module Type
| Type | Pattern | Example |
|---|---|---|
| Listener | Accept connections, spawn handler tasks | proxy/inbound.rs |
| Protocol handler | Parse/serialize protocol messages | socks5/handshake.rs |
| Relay/proxy | Bidirectional byte forwarding between streams | proxy/copy.rs, socks5/relay.rs |
| Resolver/racer | DNS resolution, connection racing | happy_eyeballs/resolver.rs, racer.rs |
| HTTP server | Hyper-based HTTP endpoint | health.rs |
2. Create Module Files
Every module is a directory under src/ with mod.rs + implementation files.
src/<module_name>/
├── mod.rs # Re-exports, shared types/constants
├── <primary>.rs # Main logic
└── (optional).rs # Additional files as needed
Register in parent: add pub mod <module_name>; to src/main.rs or parent mod.rs.
3. Apply Project Conventions
See references/patterns.md for the full pattern catalog with code templates.
Key conventions:
pub async fn run_<name>(port: u16, ...) -> anyhow::Result<()>for server entry pointstokio::spawnper connection, errors logged inside spawn (never crash the server)tracingstructured fields:debug!per-connection,info!lifecycle,error!failuresanyhow::Resulteverywhere,anyhow::bail!for protocol errors- In-module
#[cfg(test)] mod testswithtest_pair()helper for TCP stream pairs - Tests bind to port 0 for random allocation
4. Add to Cargo.toml If Needed
Only add dependencies if the new module requires crates not already in Cargo.toml. Current deps: tokio, clap, tracing, tracing-subscriber, hyper, hyper-util, http-body-util, tokio-util, anyhow, thiserror.
5. Wire Into main.rs
Add the new server to tokio::try_join! in main.rs if it runs as a long-lived server. Add CLI flags to config.rs if the module needs configuration.
What ships with it
5 files 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.

rust-network-module is a skill published in the GitHub repository fakoli/fakoli-plugins (4 stars, last pushed 24d ago), licensed MIT. It adds 78 tokens to every session and 777 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 2026-08-31.
