poolAI: Skill for Claude Code

.agents/skills/rust-skill-creator/SKILL.md

rust-skill-creator is a skill for Claude Code from platinoff/poolAI. It costs 90 tokens per session (1,861 once invoked), scanned B, original, MIT.

A generator for creating coding guidance from Rust crate or standard-library documentation. Rust is a programming language, and a crate is a reusable Rust package.

In plain words
What is it for?
Use it to create skills for crates such as Tokio, Serde, or Axum, Rust standard-library topics, or a documentation URL.
Why use it?
It avoids having to manually turn technical Rust documentation into instructions an agent can use.

Skill for Claude Code

Written for Claude Code: argument-hint in frontmatter. Also seen: agent in frontmatter; reads .claude/ paths; installed under .agents/ (shared by several agents).

This is platinoff/poolAI's own configuration. It tells Claude Code how to work on poolAI itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything poolAI configures →

Token cost

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.

Security

Grade B, and why

rust-skill-creator scanned grade B with 1 finding 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 1mo 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.

Rust Skill Creator

Version: 2.1.0 | Last Updated: 2025-01-27

Create dynamic skills for Rust crates and std library documentation.

When to Use

This skill handles requests to create skills for:

  • Third-party crates (tokio, serde, axum, etc.)
  • Rust standard library (std::sync, std::marker, etc.)
  • Any Rust documentation URL

Execution Mode Detection

CRITICAL: Check if related commands/skills are available.

This skill relies on:

  • /create-llms-for-skills command
  • /create-skills-via-llms command

Agent Mode (Plugin Install)

When the commands above are available (full plugin installation):

Workflow

1. Identify the Target
User Request Target Type URL Pattern
"create tokio skill" Third-party crate docs.rs/tokio/latest/tokio/
"create Send trait skill" Std library doc.rust-lang.org/std/marker/trait.Send.html
"create skill from URL" + URL Custom URL User-provided URL
2. Execute the Command

Use the /create-llms-for-skills command:

/create-llms-for-skills <url> [requirements]

Examples:

# For third-party crate
/create-llms-for-skills https://docs.rs/tokio/latest/tokio/

# For std library
/create-llms-for-skills https://doc.rust-lang.org/std/marker/trait.Send.html

# With specific requirements
/create-llms-for-skills https://docs.rs/axum/latest/axum/ "Focus on routing and extractors"
3. Follow-up with Skill Creation

After llms.txt is generated, use:

/create-skills-via-llms <crate_name> <llms_path> [version]

Inline Mode (Skills-only Install)

When the commands above are NOT available, create skills manually:

Step 1: Identify Target and Construct URL

Target URL Template
Crate overview https://docs.rs/{crate}/latest/{crate}/
Crate module https://docs.rs/{crate}/latest/{crate}/{module}/
Std trait https://doc.rust-lang.org/std/{module}/trait.{Name}.html
Std struct https://doc.rust-lang.org/std/{module}/struct.{Name}.html
Std module https://doc.rust-lang.org/std/{module}/index.html

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.
