How to use
- Copy the installation command and review the source package before installing it in your own agent environment.
- Check the source document for required tools, credentials and supported hosts.
- Describe your input and desired deliverable; review the output against the source material.

- Installation does not include a model subscription, API allowance or permission to access your files.
- Repository stars and installation counts describe activity, not an independent quality or security test.

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-skillscommand/create-skills-via-llmscommand
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:
bash
# 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
bash
# Using agent-browser CLI
agent-browser open "<documentation_url>"
agent-browser get text ".docblock"
agent-browser closeOr with WebFetch fallback:
WebFetch("<documentation_url>", "Extract API documentation including types, functions, and examples")Step 3: Create Skill Directory
bash
mkdir -p ~/.claude/skills/{crate_name}
mkdir -p ~/.claude/skills/{crate_name}/referencesStep 4: Generate SKILL.md
Create ~/.claude/skills/{crate_name}/SKILL.md with this template:
markdown
---
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
{Example code from documentation}
## Documentation
- `./references/overview.md` - Main overview
- `./references/{module}.md` - Module documentation
## Links
- [docs.rs](https://docs.rs/{crate})
- [crates.io](https://crates.io/crates/{crate})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 closeStep 6: Verify Skill
bash
# Check skill structure
ls -la ~/.claude/skills/{crate_name}/
cat ~/.claude/skills/{crate_name}/SKILL.mdURL Construction Helper

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.txtExample 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 creationDO NOT
- Use
best-skill-creatorfor 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 |
