Automated summary
This skill allows users to create, improve, list, and analyze Claude Code skills through a structured workflow.
Strengths
- Provides a structured process for skill creation and improvement
- Supports bilingual trigger phrases
- Allows for both global and project-level skill management
- Includes templates and reference directory
Limitations
- Requires user input for requirements
- May be limited by existing skill structure
- Does not automatically test skills
Use this skill when you need to create a new Claude Code skill or improve an existing one.
Do not use this skill for tasks unrelated to Claude Code skill management, such as general coding or file editing.
Security analysis
CautionThe skill-manager is a meta-skill that uses Bash for directory listing and file operations, which is necessary for its function. It does not contain any suspicious payloads like curl|sh, data exfiltration, or safety bypasses. However, because it has the ability to write and execute shell commands, it warrants caution.
- •Uses Bash to list directories and potentially run other shell commands, which could be leveraged if the skill is compromised or misused, but the intended use is safe.
- •Skill creation and improvement involve writing files that could be modified to include malicious instructions, but the skill itself does not inherently perform destructive or exfiltrating actions.

Skill Manager
Manage Claude Code skills: create, improve, list, and analyze.
Usage
/skill-manager create [skill-name] # Create a new skill
/skill-manager improve [skill-name] # Improve an existing skill
/skill-manager list # List all skills
/skill-manager [skill-name] # Analyze/improve (default)
Parse $ARGUMENTS to determine the action. If no action is specified, default to improve if a skill name is given.
Current Skills
Global skills:
!ls -1 ~/.claude/skills/ 2>/dev/null || echo "(none)"
Project skills:
!ls -1 .claude/skills/ 2>/dev/null || echo "(none)"
Action: create
Create a new skill from scratch.
Workflow
-
Gather Requirements via AskUserQuestion:
- Skill name (kebab-case)
- Purpose and description
- Trigger phrases (Japanese + English)
- Required tools
- Location:
~/.claude/skills/(global) or.claude/skills/(project)
-
Create Directory Structure:
skill-name/ ├── SKILL.md # Required ├── references/ # Optional: Reference docs ├── templates/ # Optional: Template files └── examples/ # Optional: Usage examples -
Write SKILL.md using the template in
templates/basic.mdortemplates/advanced.md -
Report Success: Show the invoke command
/skill-name
Action: improve
Improve an existing skill.
Workflow
-
Locate the Skill:
- Check
~/.claude/skills/{skill-name}/SKILL.md - Check
.claude/skills/{skill-name}/SKILL.md - If not found, list available skills and ask user
- Check
-
Analyze Current State:
- Read SKILL.md and all related files
- Identify issues:
- Vague or missing trigger phrases
- Overly broad or missing tool restrictions
- Unclear instructions
- Missing error handling
- No examples
-
Suggest Improvements via AskUserQuestion:
- Present findings and recommendations
- Ask what the user wants to improve:
- Trigger phrases (more specific, bilingual)
- Instructions (clearer workflow)
- Tool restrictions (security)
- Examples (usage clarity)
- Structure (add references/, templates/)
-
Apply Changes: Edit SKILL.md and related files
-
Report Changes: Summarize what was improved
Action: list
List all available skills with their status.
Workflow
-
Scan Directories:
~/.claude/skills/(global).claude/skills/(project-local)
-
For Each Skill, Report:
- Name and version
- Description (first line)
- Trigger phrases count
- Allowed tools
- Location (global/project)
-
Output Format:
📁 Global Skills (~/.claude/skills/) ├── skill-name (v1.0.0) - Description │ └── Triggers: "phrase1", "phrase2" 📁 Project Skills (.claude/skills/) └── (none)

description: This skill should be used when the user asks to "create a migration", "generate migration", "マイグレーション作成".
Bad:
description: Helps with database tasks. # Too vague, won't trigger
Dynamic Content
Embed shell output in SKILL.md:
!`git status --short`

Best Practices
- Specific triggers: Include exact phrases users will say (quoted)
- Bilingual: Japanese + English trigger phrases
- Restrict tools: Use
allowed-toolsfor security - Keep SKILL.md concise: Put reference docs in
references/ - Version your skills: Update version on changes
- Test triggers: Verify the skill activates on expected phrases
From the file to a first result
The download contains exactly the content displayed on this page. This copy may differ from the latest version in the source repository.
View the source and supporting filesThis download contains SKILL.md only. Any scripts, references, templates and dependencies are not included. Get the required files from the source, preserving their directory structure, before continuing.
1. Download the file
Download SKILL.mdFrom the root of a test project, save the file as .skill-downloads/claude-code-skill-manager-mm8o529p/SKILL.md, or use the command below. This folder is for inspecting the skill before installation.
Command for macOS/Linux or WSL: requires a POSIX shell and curl. On Windows without WSL, use the download button and create the folder manually.
mkdir -p '.skill-downloads/claude-code-skill-manager-mm8o529p' && curl --fail --show-error --location 'https://skills-guides.com/api/skills/claude-code-skill-manager-mm8o529p/download' --output '.skill-downloads/claude-code-skill-manager-mm8o529p/SKILL.md.part' && mv '.skill-downloads/claude-code-skill-manager-mm8o529p/SKILL.md.part' '.skill-downloads/claude-code-skill-manager-mm8o529p/SKILL.md'2. Check prerequisites
Read SKILL.md before using it. If it references scripts or external services, inspect them and prepare the required access in your test environment.
No recognized prerequisites section in this file. This does not mean it is self-contained: libraries, tools and access requirements may be mentioned elsewhere in the content or source repository.
The platforms on this page are catalog indications. The paths below follow tool documentation; they do not prove this skill has been run in those tools. No minimum tool version is confirmed for this listing.
3. Load the skill
After inspection, copy the complete folder into your project using one of the commands below, then open a new tool session. The command stops if a folder with the same name already exists: compare the files before replacing it.
Claude Code
test -f '.skill-downloads/claude-code-skill-manager-mm8o529p/SKILL.md' && test -s '.skill-downloads/claude-code-skill-manager-mm8o529p/SKILL.md' && mkdir -p '.claude/skills' && test ! -e '.claude/skills/skill-manager' && cp -R '.skill-downloads/claude-code-skill-manager-mm8o529p' '.claude/skills/skill-manager'OpenSkills
OpenSkills must already be installed. The local install/read procedure is checked with OpenSkills 1.5.0, which requires Node.js ≥ 20.6.0. Catalog slugs are not resolved automatically.
Official OpenSkills installationopenskills install './.skill-downloads/claude-code-skill-manager-mm8o529p'openskills read 'claude-code-skill-manager-mm8o529p'Reading should display the installed file content and its base directory. It does not run the skill or install its dependencies.
For an agent that reads AGENTS.md, then sync the index. This command changes AGENTS.md: review the diff before using it.
openskills syncManual method or another tool: attach SKILL.md to a conversation, or open it in an agent that can read files. Include any required supporting resources. No universal folder is recognized by every tool.
4. Try a first task
Use a short, synthetic input: an API endpoint, a small document or an interface brief. In a new conversation, attach the file or give the agent its path, then adapt this request:
Read .skill-downloads/claude-code-skill-manager-mm8o529p/SKILL.md and apply its instructions to this example: [describe a test input]. Identify any missing files, dependencies or access. Produce the result requested by the skill without inventing data or running unreviewed scripts.Expected result: output matching the skill instructions, or a precise list of missing prerequisites. A read confirmation alone does not validate a first use. If an external resource is unavailable, that path remains untested.
React Hook Form Best Practices
Development
Master React Hook Form: avoid anti-patterns, manage subscriptions, and handle reset, dirty state, and controlled inputs correctly.
Emotion to Mantine Migration
Development
Migrate Emotion styled-components to Mantine components with style props and CSS modules. Use when converting .styled.tsx files or removing @emotion imports.
Scope Creep Detector
Development
Analyzes git diffs against a stated intent to detect scope creep, unrelated files, broad PRs, and oversized changes, then suggests keep, split, or justify actions.
