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

Step 2: Fetch Documentation

# Using agent-browser CLI
agent-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 documentation
agent-browser open "https://docs.rs/{crate}/latest/{crate}/{module}/"
agent-browser get text ".docblock" > ~/.claude/skills/{crate_name}/references/{module}.md
agent-browser close

Step 6: Verify Skill

# Check skill structure
ls -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 generation
4. 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 documentation
4. Create: ~/.claude/skills/tokio/SKILL.md
5. 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 traits
2. (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 manually
3. 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/

Error Handling

Error	Cause	Solution
Commands not found	Skills-only install	Use inline mode
URL not found	Invalid crate/module	Verify crate exists on crates.io
Empty documentation	API changed	Use alternative selectors
Permission denied	Directory issue	Check ~/.claude/skills/ permissions
