- Extract it into a folder your agent can access.
- Paste one of the prompts below and point your agent at the extracted folder.
## Suggested prompts
### New install

```text
I downloaded a skill package from Yavira. Read SKILL.md from the extracted folder and install it by following the included instructions. Tell me what you changed and call out any manual steps you could not complete.
```
### Upgrade existing

```text
I downloaded an updated skill package from Yavira. Read SKILL.md from the extracted folder, compare it with my current installation, and upgrade it while preserving any custom configuration unless the package docs explicitly say otherwise. Summarize what changed and any follow-up checks I should run.

## Documentation

### Skill Writer

Write well-structured, effective SKILL.md files for the ClawdHub registry. Covers the skill format specification, frontmatter schema, content patterns, example quality, and common anti-patterns.

### When to Use

Creating a new skill from scratch
Structuring technical content as an agent skill
Writing frontmatter that the registry indexes correctly
Choosing section organization for different skill types
Reviewing your own skill before publishing

### The SKILL.md Format

A skill is a single Markdown file with YAML frontmatter. The agent loads it on demand and follows its instructions.

---
name: my-skill-slug
description: One-sentence description of when to use this skill.
metadata: {"clawdbot":{"emoji":"🔧","requires":{"anyBins":["tool1","tool2"]},"os":["linux","darwin","win32"]}}
---

# Skill Title

One-paragraph summary of what this skill covers.

## When to Use

- Bullet list of trigger scenarios

## Main Content Sections

### Subsection with examples

Code blocks, commands, patterns...

## Tips

- Practical advice bullets

### name (required)

The skill's slug identifier. Must match what you publish with.

name: my-skill

Rules:

Lowercase, hyphenated: csv-pipeline, git-workflows
No spaces, no underscores
Keep it short and descriptive (1-3 words)
Check for slug collisions before publishing: npx molthub@latest search "your-slug"

### description (required)

The single most important field. This is what:

The registry indexes for semantic search (vector embeddings)
The agent reads to decide whether to activate the skill
Users see when browsing search results

# GOOD: Specific triggers and scope
description: Write Makefiles for any project type. Use when setting up build automation, defining multi-target builds, managing dependencies between tasks, creating project task runners, or using Make for non-C projects (Go, Python, Docker, Node.js). Also covers Just and Task as modern alternatives.

# BAD: Vague, no triggers
description: A skill about Makefiles.

# BAD: Too long (gets truncated in search results)
description: This skill covers everything you need to know about Makefiles including variables, targets, prerequisites, pattern rules, automatic variables, phony targets, conditional logic, multi-directory builds, includes, silent execution, and also covers Just and Task as modern alternatives to Make for projects that use Go, Python, Docker, or Node.js...

Pattern for effective descriptions:

[What it does]. Use when [trigger 1], [trigger 2], [trigger 3]. Also covers [related topic].

### metadata (required)

JSON object with the clawdbot schema:

metadata: {"clawdbot":{"emoji":"🔧","requires":{"anyBins":["make","just"]},"os":["linux","darwin","win32"]}}

Fields:

emoji: Single emoji displayed in registry listings
requires.anyBins: Array of CLI tools the skill needs (at least one must be available)
os: Array of supported platforms: "linux", "darwin" (macOS), "win32" (Windows)

Choose requires.anyBins carefully:

# Good: lists the actual tools the skill's commands use
"requires": {"anyBins": ["docker", "docker-compose"]}

# Bad: lists generic tools every system has
"requires": {"anyBins": ["bash", "echo"]}

# Good for skills that work via multiple tools
"requires": {"anyBins": ["make", "just", "task"]}

### The "When to Use" Section

Always include this immediately after the title paragraph. It tells the agent (and the user) the specific scenarios where this skill applies.

## When to Use

- Automating build, test, lint, deploy commands
- Defining dependencies between tasks (build before test)
- Creating a project-level task runner
- Replacing long CLI commands with short targets

Rules:

4-8 bullet points
Each bullet is a concrete scenario, not an abstract concept
Start with a verb or gerund: "Automating...", "Debugging...", "Converting..."
Don't repeat the description field verbatim

### Main Content Sections

Organize by task, not by concept. The agent needs to find the right command for a specific situation.

## GOOD: Organized by task
## Encode and Decode
### Base64
### URL Encoding
### Hex

## BAD: Organized by abstraction
## Theory of Encoding
## Encoding Types
## Advanced Topics

### Code Blocks

Every section should have at least one code block. Skills without code blocks are opinions, not tools.

## GOOD: Concrete, runnable example
\`\`\`bash
# Encode a string to Base64
echo -n "Hello, World!" | base64
# SGVsbG8sIFdvcmxkIQ==
\`\`\`

## BAD: Abstract description
Base64 encoding converts binary data to ASCII text using a 64-character alphabet...

Code block best practices:

Always specify the language (bash, python, javascript, yaml, sql, etc.)
Show the output in a comment below the command
Use realistic values, not foo/bar (use myapp, api-server, real IP formats)
Include the most common case first, then variations
Add inline comments for non-obvious flags or arguments

### Multi-Language Coverage

If a skill applies across languages, use consistent section structure:

## Hashing

### Bash
\`\`\`bash
echo -n "Hello" | sha256sum

### JavaScript

const crypto = require('crypto');
crypto.createHash('sha256').update('Hello').digest('hex');

### Python

import hashlib
hashlib.sha256(b"Hello").hexdigest()

Order: Bash first (most universal), then by popularity for the topic.

### The "Tips" Section

End every skill with a Tips section. These are the distilled wisdom — the things that save hours of debugging.

\`\`\`markdown
## Tips

- The number one Makefile bug: using spaces instead of tabs for indentation.
- SHA-256 is the standard for integrity checks. MD5 is fine for dedup but broken for cryptographic use.
- Never schedule critical cron jobs between 1:00-3:00 AM if DST applies.

Rules:

5-10 bullets
Each tip is a standalone insight (no dependencies on other tips)
Prioritize gotchas and non-obvious behavior over basic advice
No "always use best practices" platitudes

### CLI Tool Reference

For skills about a specific tool or command family.

---
name: tool-name
description: [What tool does]. Use when [scenario 1], [scenario 2].
metadata: {"clawdbot":{"emoji":"🔧","requires":{"anyBins":["tool-name"]}}}
---

# Tool Name

[One paragraph: what it does and why you'd use it.]

## When to Use
- [4-6 scenarios]

## Quick Reference
[Most common commands with examples]

## Common Operations
### [Operation 1]
### [Operation 2]

## Advanced Patterns
### [Pattern 1]

## Troubleshooting
### [Common error and fix]

## Tips

### Language/Framework Reference

For skills about patterns in a specific language or framework.

---
name: pattern-name
description: [Pattern] in [language/framework]. Use when [scenario 1], [scenario 2].
metadata: {"clawdbot":{"emoji":"📐","requires":{"anyBins":["runtime"]}}}
---

# Pattern Name

## When to Use

## Quick Reference
[Cheat sheet / syntax summary]

## Patterns
### [Pattern 1 — with full example]
### [Pattern 2 — with full example]

## Cross-Language Comparison (if applicable)

---
name: workflow-name
description: [Workflow description]. Use when [scenario 1], [scenario 2].
metadata: {"clawdbot":{"emoji":"🔄","requires":{"anyBins":["tool1","tool2"]}}}
---

# Workflow Name

## When to Use

## Prerequisites
[What needs to be set up first]

## Step-by-Step
### Step 1: [Action]
### Step 2: [Action]
### Step 3: [Action]

## Variations
### [Variation for different context]

## Troubleshooting

## Tips

### Too abstract

# BAD
## Error Handling
Error handling is important for robust applications. You should always
handle errors properly to prevent unexpected crashes...

# GOOD
## Error Handling
\`\`\`bash
# Bash: exit on any error
set -euo pipefail

# Trap for cleanup on exit
trap 'rm -f "$TMPFILE"' EXIT

### Too narrow

\`\`\`markdown
# BAD: Only useful for one specific case
---
name: react-useeffect-cleanup
description: How to clean up useEffect hooks in React
---

# GOOD: Broad enough to be a real reference
---
name: react-hooks
description: React hooks patterns. Use when working with useState, useEffect, useCallback, useMemo, custom hooks, or debugging hook-related issues.
---

### Wall of text without examples

If any section goes more than 10 lines without a code block, it's too text-heavy. Break it up with examples.

### Missing cross-references

If your skill mentions another tool or concept that has its own skill, note it:

# For Docker networking issues, see the \`container-debug\` skill.
# For regex syntax details, see the \`regex-patterns\` skill.

### Outdated commands

Verify every command works on current tool versions. Common traps:

Docker Compose: docker-compose (v1) vs. docker compose (v2)
Python: pip vs. pip3, python vs. python3
Node.js: CommonJS (require) vs. ESM (import)

### Size Guidelines

MetricTargetToo ShortToo LongTotal lines300-550< 150> 700Sections5-10< 3> 15Code blocks15-40< 8> 60Tips5-10< 3> 15

A skill under 150 lines probably lacks examples. A skill over 700 lines should be split into two skills.

### Publishing Checklist

Before publishing, verify:

Frontmatter is valid YAML — test by pasting into a YAML validator
Description starts with what the skill does — not "This skill..." or "A skill for..."
Every section has at least one code block — no text-only sections in the main content
Commands actually work — test in a clean environment
No placeholder values left — search for TODO, FIXME, example.com used as real URLs
Slug is available — npx molthub@latest search "your-slug" returns no exact match
requires.anyBins lists real dependencies — tools the skill's commands actually invoke
Tips section exists — with 5+ actionable, non-obvious bullets

### Publishing

# Publish a new skill
npx molthub@latest publish ./skills/my-skill \\
  --slug my-skill \\
  --name "My Skill" \\
  --version 1.0.0 \\
  --changelog "Initial release"

# Update an existing skill
npx molthub@latest publish ./skills/my-skill \\
  --slug my-skill \\
  --name "My Skill" \\
  --version 1.1.0 \\
  --changelog "Added new section on X"

# Verify it's published
npx molthub@latest search "my-skill"

### Tips

The description field is your skill's search ranking. Spend more time on it than any single content section. Include the specific verbs and nouns users would search for.
Lead with the most common use case. If 80% of users need "how to encode Base64", put that before "how to convert between MessagePack and CBOR."
Every code example should be copy-pasteable. If it needs setup that isn't shown, add the setup.
Write for the agent, not the human. The agent needs unambiguous instructions it can follow step by step. Avoid "you might want to consider" — say "do X when Y."
Test your skill by asking an agent to use it on a real task. If the agent can't follow the instructions to produce a correct result, the skill needs work.
Prefer bash code blocks for commands, even in language-specific skills. The agent often operates via shell, and bash blocks signal "run this."
Don't duplicate what --help already provides. Focus on patterns, combinations, and the non-obvious things that --help doesn't teach.
Version your skills semantically: patch for typo fixes, minor for new sections, major for restructures. The registry tracks version history.
