skill-extractor

Package any installed OpenClaw skill into a clean, shareable ZIP. External runtime files referenced in SKILL.md are detected, staged under _external/, and documented — so a new install knows exactly where every file belongs and can reproduce full functionality.

All file operations are local only. Nothing is transmitted anywhere. The user confirms what gets included before anything is zipped.

Agent Rules

• Always list available skills before asking for selection (unless skill name is already given)
• Always work on a staging copy — never modify the original skill directory or any external paths
• Always show the user what external files were found and get explicit confirmation before zipping
• Files are packaged as-is — values are not modified. Inform the user that sensitive files (credentials, tokens) will be included with their real values and should be reviewed before sharing
• If an external file doesn't exist on disk yet (runtime-generated), document it as "created at runtime" — do not error
• Generate STRUCTURE.md inside the staging folder before zipping
• Default ZIP output: the user's Desktop — confirm with user first
• If ZIP already exists at target, overwrite it
• Clean up staging after a successful ZIP
• If any step fails, leave staging intact and report clearly

Step 1 — List Available Skills

Scan all known OpenClaw skill locations (workspace skills folder, user-local skills folder, and the bundled npm package skills folder) for subdirectories that contain a SKILL.md. Present the list with skill name and source. Ask which to export.

Step 2 — Locate Skill

Find the skill folder by name. If not found, report and stop.

Step 3 — Stage Skill Files

Create a hidden temp staging folder inside the workspace named after the skill. Copy all files from the skill directory into it. Originals are never touched.

Step 4 — Detect External Files

Read the SKILL.md from the original skill directory. Extract all path-like strings that begin with a user home or app-data prefix (home dir shorthands and platform app-data equivalents). Resolve each to an absolute path.

For each path:

• If it is a file that exists: add it to the external files list.
• If it is a directory that exists: add all files inside it recursively to the list.
• If it doesn't exist yet: record it as a "created at runtime" entry.

Do not copy anything yet. Build the list first — it goes to the user for review in the next step.

Step 5 — Confirm with User

Present the user with everything that will be included in the ZIP:

1. All files from the skill directory
2. The full list of detected external files with their resolved paths

Clearly warn: "These files will be packaged with their real values — including any credentials, tokens, or sensitive config. Review before sharing the ZIP."

Ask: *"Proceed with packaging these files?"*

• If yes: stage the external files into _external/, mirroring the directory structure relative to the user's home, then continue.
• If no: abort and clean up staging. Do not create a ZIP.

Step 6 — Generate STRUCTURE.md

Write STRUCTURE.md into the staging dir with these sections in order:

Header — skill name, generation timestamp, one-line purpose statement.

Folder Layout — ASCII tree of the staging dir. Directories before files at each level, both sorted alphabetically. Use standard tree connectors (├──, └──, │). Directory names end with /.

File Descriptions table — two columns: relative file path and one-line purpose. Describe each file by what it does rather than its type. Well-known skill files have fixed descriptions:

External Files table — only if external files were detected. Three columns: file path inside the ZIP | target install path on the machine | notes. Determine the notes value by this logic:

Follow the table with a brief note on how to place _external/ files at their target paths on both Windows and Unix systems.

Install Instructions — three options:

• Option A: install via ClawhHub if the skill is published
• Option B: manual — copy the skill folder into the workspace skills directory, place any _external/ files at their target paths, confirm with openclaw skills list
• Option C: local clawhub install, then handle _external/ files manually

Step 7 — Zip and Deliver

Confirm the output path with the user (default: the user's Desktop). Remove any existing ZIP at that path first. Compress the staging dir. Report the saved path and file size. Delete the staging folder.
