Rust Skill Creator

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

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

Step 2: Fetch Documentation

# Using agent-browser CLIagent-browser open "<documentation_url>"agent-browser get text ".docblock"agent-browser close

Or with WebFetch fallback:

WebFetch("<documentation_url>", "Extract API documentation including types, functions, and examples")

Step 3: Create Skill Directory

mkdir -p ~/.claude/skills/{crate_name}mkdir -p ~/.claude/skills/{crate_name}/references

Step 4: Generate SKILL.md

Create ~/.claude/skills/{crate_name}/SKILL.md with this template:

---name: {crate_name}description: "Documentation for {crate_name} crate. Keywords: {keywords}"---
# {Crate Name}
> **Version:** {version} | **Source:** docs.rs
## Overview
{Brief description from documentation}
## Key Types
### {Type1}{Description and usage}
### {Type2}{Description and usage}
## Common Patterns
{Usage patterns extracted from documentation}
## Examples
```rust{Example code from documentation}

Documentation

• ./references/overview.md - Main overview
• ./references/{module}.md - Module documentation

Links

• docs.rs
• crates.io

### Step 5: Generate Reference Files
For each major module or type, create a reference file:
```bash# Fetch and save module documentationagent-browser open "https://docs.rs/{crate}/latest/{crate}/{module}/"agent-browser get text ".docblock" > ~/.claude/skills/{crate_name}/references/{module}.mdagent-browser close

Step 6: Verify Skill

# Check skill structurels -la ~/.claude/skills/{crate_name}/cat ~/.claude/skills/{crate_name}/SKILL.md

Example Interactions

Example 1: Create Crate Skill (Agent Mode)

User: "Create a dynamic skill for tokio"
Claude:1. Identify: Third-party crate "tokio"2. Execute: /create-llms-for-skills https://docs.rs/tokio/latest/tokio/3. Wait for llms.txt generation4. Execute: /create-skills-via-llms tokio ~/tmp/{timestamp}-tokio-llms.txt

Example 2: Create Crate Skill (Inline Mode)

User: "Create a dynamic skill for tokio"
Claude:1. Identify: Third-party crate "tokio"2. Fetch: agent-browser open "https://docs.rs/tokio/latest/tokio/"3. Extract documentation4. Create: ~/.claude/skills/tokio/SKILL.md5. Create: ~/.claude/skills/tokio/references/6. Save reference files for key modules (sync, task, runtime, etc.)

Example 3: Create Std Library Skill

User: "Create a skill for Send and Sync traits"
Claude:1. Identify: Std library traits2. (Agent Mode) Execute: /create-llms-for-skills https://doc.rust-lang.org/std/marker/trait.Send.html https://doc.rust-lang.org/std/marker/trait.Sync.html   (Inline Mode) Fetch each URL, create skill manually3. Complete skill creation

DO NOT

• Use best-skill-creator for Rust-related skill creation
• Guess documentation URLs without verification
• Skip documentation fetching step

Output Location

All generated skills are saved to: ~/.claude/skills/
