Skill Lister

VerifiedCaution

Lists all AgenticDev skills installed in the project by scanning the .claude/skills/ directory. Extracts metadata from each skill's SKILL.md file, including name, description, and available scripts, and presents it in a readable or JSON format. Use this at the start of a session to discover which skills are available or when verifying the project's skill setup.

Our review

Lists all installed AgenticDev skills in a project by scanning the .claude/skills/ directory.

Strengths

  • Provides a quick overview of all available skills without manual exploration
  • Outputs both human-readable and JSON formats for programmatic use
  • Integrates with AI agent bootstrap to inform agents of their capabilities

Limitations

  • Only works if skills follow the SKILL.md convention with YAML frontmatter
  • Does not add or modify skills—only lists them
  • May fail if directory permissions are insufficient
When to use it

Use this skill at the start of a work session or when onboarding a new AI agent to discover all available skills.

When not to use it

Avoid using it when you already know the skills or when you need to execute a specific skill without listing everything.

Security analysis

Caution
Quality score90/100

The skill uses bash to run a script that scans directories. While it claims to be safe and read-only, the execution of arbitrary bash commands is inherently powerful and could be misused if the script is compromised. No destructive or exfiltrating actions are described, so it's not 'risky', but the use of bash warrants caution.

Findings
  • The skill instructs to execute a local bash script, which could be malicious or tampered with. Although intended to be read-only, running any script carries inherent risk.

name: skill-lister description: Use this skill to discover all available AgenticDev skills and their capabilities. Provides a bootstrap context for AI agents by listing all skills, their descriptions, and script paths from the .claude/skills/ directory.

Skill Lister

Purpose

Provide a comprehensive overview of all available AgenticDev skills in the project. The skill-lister scans the .claude/skills/ directory, extracts skill metadata from SKILL.md files, and returns a formatted list of all discovered skills with their descriptions and script paths. This enables AI agents to quickly understand what capabilities are available without manually exploring the directory structure.

When to Use

Use this skill in the following situations:

  • At the beginning of any work session to understand available AgenticDev capabilities
  • When onboarding to a new project using AgenticDev
  • Before deciding which skill to use for a particular task
  • When documenting or auditing the project's AgenticDev setup
  • To verify that all expected skills are installed and accessible

Prerequisites

  • The project must have a .claude/skills/ directory
  • Skills should follow the convention of including SKILL.md files with YAML frontmatter
  • No additional tools required (pure bash implementation)

Workflow

Step 1: Run the Skill Lister

Execute the helper script to scan all skills in the .claude/skills/ directory:

bash .claude/skills/skill-lister/scripts/list-skills.sh

This will output a human-readable summary showing each skill's metadata including:

  • Skill name
  • Description
  • Available scripts

For machine-readable JSON output (useful for programmatic processing):

bash .claude/skills/skill-lister/scripts/list-skills.sh -j

Step 2: Review the Skills List

The scanner returns information about all skills found in .claude/skills/, including:

  • Skill name: The identifier for the skill (from YAML frontmatter)
  • Description: What the skill does and when to use it
  • Script paths: All executable scripts available for the skill
  • Directory: Location of the skill in the filesystem

Step 3: Choose the Appropriate Skill

Based on the output, select the skill that best matches your current task:

  • Need to understand documentation? → Use doc-indexer
  • Starting work on an issue? → Use issue-executor
  • Proposing a change? → Use spec-authoring
  • Planning a sprint? → Use sprint-planner
  • Setting up a new project? → Use project-init

Error Handling

No Skills Directory Found

Symptom: Script reports that .claude/skills/ directory doesn't exist

Solution:

  • Verify you're in the project root directory
  • Run project-init skill to set up AgenticDev
  • Check if skills are installed in a different location

Missing SKILL.md Files

Symptom: Script lists skills but shows no metadata

Solution:

  • Verify that each skill directory contains a SKILL.md file
  • Check that SKILL.md files have proper YAML frontmatter with name and description fields
  • Run validation script if available: bash scripts/validate-skills.sh

No Scripts Found

Symptom: Skill is listed but shows no scripts

Solution:

  • Verify that the skill's scripts/ directory exists and contains executable files
  • Check file permissions: chmod +x .claude/skills/*/scripts/*
  • Some skills may not have scripts (documentation-only skills)

Permission Denied

Symptom: Cannot read skill directories or files

Solution:

  • Check directory permissions: ls -la .claude/skills/
  • Ensure you have read access to the skills directory
  • Verify the script itself is executable: chmod +x .claude/skills/skill-lister/scripts/list-skills.sh

Notes

  • Bootstrap context: Designed to be run by agent-integrator to provide AI agents with skill discovery capability
  • Lightweight: Minimal dependencies, works with standard bash tools
  • Extensible: Automatically discovers new skills as they're added
  • JSON support: Can output structured data for integration with other tools
  • Convention-based: Relies on standard AgenticDev skill structure (SKILL.md + scripts/)
  • Safe to run: Read-only operation with no side effects
  • Discovery pattern: Similar to doc-indexer but for skills instead of documentation
