Inspecting Skills

Discover Python code across skills and enable universal imports. Solves the dash-underscore naming mismatch between skill directories (e.g., `browsing-bluesky`) and Python imports (e.g., `browsing_bluesky`).

Installation

import sys
sys.path.insert(0, '/home/user/claude-skills')
from inspecting_skills import setup_skill_path, skill_import

Quick Start

Import a Skill

from inspecting_skills import skill_import

# Import by skill name (dash or underscore form)
bsky = skill_import("browsing-bluesky")
posts = bsky.search_posts("python")

# Import specific functions
search, profile = skill_import("browsing-bluesky", ["search_posts", "get_profile"])

Enable Transparent Imports

from inspecting_skills import setup_skill_path

# Configure once at session start
setup_skill_path("/home/user/claude-skills")

# Now import skills directly (underscore form)
from browsing_bluesky import search_posts, get_profile
from remembering import remember, recall

Discover Available Skills

from inspecting_skills import list_importable_skills

skills = list_importable_skills()
for s in skills:
    print(f"{s['name']} -> import {s['module_name']}")

Core Functions

Discovery

| Function | Purpose | |----------|---------| | `discover_skill(path)` | Analyze a single skill directory | | `discover_all_skills(root)` | Find all skills with Python code | | `find_skill_by_name(name, root)` | Find skill by name (either form) | | `skill_name_to_module(name)` | Convert "browsing-bluesky" to "browsing_bluesky" |

Indexing

| Function | Purpose | |----------|---------| | `index_skill(layout)` | Extract symbols from a discovered skill | | `index_all_skills(root)` | Index all skills in repository | | `generate_registry(root, output)` | Create registry.json manifest |

Importing

| Function | Purpose | |----------|---------| | `setup_skill_path(root)` | Enable transparent skill imports | | `skill_import(name, symbols)` | Import skill or specific symbols | | `register_skill(name, path)` | Register skill at custom path | | `list_importable_skills()` | List all importable skills |

Skill Layouts

Skills organize Python code in three patterns:

1. Scripts Directory

browsing-bluesky/
  SKILL.md
  __init__.py          # Re-exports from scripts/
  scripts/
    __init__.py
    bsky.py            # Main implementation

2. Root-Level Modules

remembering/
  SKILL.md
  __init__.py          # Re-exports functions
  memory.py            # Core functionality
  boot.py
  config.py

3. Simple Package

simple-skill/
  SKILL.md
  __init__.py          # Contains all code

Generating a Registry

Create a `registry.json` for offline symbol lookup:

from inspecting_skills import generate_registry
from pathlib import Path

registry = generate_registry(
    Path("/home/user/claude-skills"),
    output_path=Path("registry.json")
)

# Registry structure:
# {
#   "version": "1.0.0",
#   "skills": {
#     "browsing-bluesky": {
#       "module_name": "browsing_bluesky",
#       "exports": ["search_posts", "get_profile", ...],
#       "modules": [...]
#     }
#   }
# }

Indexing a Single Skill

from inspecting_skills import discover_skill, index_skill
from pathlib import Path

# Discover the skill layout
layout = discover_skill(Path("/home/user/claude-skills/remembering"))
print(f"Layout: {layout.layout_type}")
print(f"Has __init__.py: {layout.has_init}")
print(f"Python files: {[f.name for f in layout.python_files]}")

# Index symbols
index = index_skill(layout)
for module in index.modules:
    print(f"\n{module.file_path}:")
    for sym in module.symbols:
        print(f"  {sym.kind} {sym.name}{sym.signature or ''}")

Integration with tree-sitting

This skill complements `tree-sitting`, which extracts code structure at runtime:

• **tree-sitting**: AST-derived structure via tree-sitter, multi-language
• **inspecting-skills**: Runtime import support, Python-focused, dynamic discovery

Use both together: 1. `tree-sitting` for navigation and code review 2. `inspecting-skills` for actual code imports and execution

Troubleshooting

Import Errors

# If skill_import fails, check:

# 1. Skill exists and has __init__.py
from inspecting_skills import discover_skill
layout = discover_skill(Path("/path/to/skill"))
print(layout.has_init)  # Must be True for importing

# 2. Skills root is configured
from inspecting_skills import get_skills_root
print(get_skills_root())

# 3. Symbol is exported in __all__
import ast
init_code = open("/path/to/skill/__init__.py").read()
# Check for __all__ definition

Path Not Found

# Manually set skills root
from inspecting_skills import set_skills_root
set_skills_root("/home/user/claude-skills")
