A skill your agent uses when creating skills for Rust crates or std library documentation.

  • Works in 3 steps: Identify the Target → Execute the Command → Follow-up with Skill Creation
  • Creating skills for Rust crates
  • SKILL.md covers When to Use, Execution Mode Detection, Agent Mode (Plugin Install) and Inline Mode (Skills-only…, plus 8 more sections
  • Reaches docs.rs and doc.rust-lang.org

What it does

Rust Skill Creator is an agent skill from fjrevoredo/mini-diarium. Use when creating skills for Rust crates or std library documentation. Keywords: create rust skill, create crate skill, create std skill, 创建 rust skill, 创建 crate skill, 创建 std skill, 动态 rust skill, 动态 crate skill, skill for tokio, skill for serde, skill for axum, generate rust skill, rust 技能, crate 技能, 从文档创建skill, from docs create skill

Its SKILL.md is about 1.7k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in Agent Workflows, covering Skill authoring. It works with Rust. The repository describes itself as: A local-only journal with serious encryption. Free, open source, and never touches the internet. The licence is MIT.

When your agent uses it

  • Creating skills for Rust crates
  • Std library documentation

Example prompts

  • “/rust-skill-creator”

Workflow steps

3 steps, taken from the step headings in SKILL.md.

  1. Identify the Target
  2. Execute the Command
  3. Follow-up with Skill Creation

What it can do on your machine

Read from SKILL.md and the folder at commit 3ddc537. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    No scripts in the folder and no shell commands in SKILL.md (its code samples are bash and markdown).

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    Hosts in commands or code, which the agent is likely to contact:

    • docs.rs
    • doc.rust-lang.org

    Also links to:

    • crates.io

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Rust Skill Creator loads about 1.7k tokens when it runs. Until then it costs about 89 tokens; SKILL.md has 340 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~89
When it runs · the whole SKILL.md, loaded when a task matches
~1.7k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

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 RequestTarget TypeURL Pattern
"create tokio skill"Third-party cratedocs.rs/tokio/latest/tokio/
"create Send trait skill"Std librarydoc.rust-lang.org/std/marker/trait.Send.html
"create skill from URL" + URLCustom URLUser-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
TargetURL Template
Crate overviewhttps://docs.rs/{crate}/latest/{crate}/
Crate modulehttps://docs.rs/{crate}/latest/{crate}/{module}/
Std traithttps://doc.rust-lang.org/std/{module}/trait.{Name}.html
Std structhttps://doc.rust-lang.org/std/{module}/struct.{Name}.html
Std modulehttps://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 close

Or 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}/references
Step 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

```rust
{Example code from documentation}

Documentation

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

### 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
bash
# 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/
