Fetch URLs

Fetch web content via a Python script. Three modes: full page, single anchor section, or anchor discovery.

Commands

Full page as markdown:

uv run "$SKILLS_DIR/scripts/fetch_anchor.py" "<url>"

Single anchor section (URL must contain #fragment):

uv run "$SKILLS_DIR/scripts/fetch_anchor.py" "<url>#<anchor>" --only-current-anchor

List all anchors (shows heading hierarchy):

uv run "$SKILLS_DIR/scripts/fetch_anchor.py" "<url>" --list-anchors

Pagination (for large pages or sections):

uv run "$SKILLS_DIR/scripts/fetch_anchor.py" "<url>" --max-length 5000 --start-index 5000

Raw HTML (combine with any mode above):

uv run "$SKILLS_DIR/scripts/fetch_anchor.py" "<url>" --raw

Flags

Flag	Description
--only-current-anchor	Return only the section matching the URL's #fragment
--raw	Output raw HTML instead of markdown
--max-length N	Limit output to N characters (enables pagination)
--start-index N	Start at character N (use with --max-length for next page)
--list-anchors	List all anchors, grouped by heading hierarchy

Workflow

1. Full page: pass the URL. HTML is simplified via readability, then converted to markdown. Non-HTML (JSON, plain text) is returned as-is.
2. Anchor mode: if the user provides a URL with #fragment, pass it with --only-current-anchor. The fragment is extracted from the URL automatically. Captures the full section including all sub-headings at lower levels.
3. Discovery: if the user asks for a section but the anchor ID is unknown, use --list-anchors first. Output shows heading hierarchy with indentation and levels (h1-h6) so you can pick the right anchor.
4. Pagination: for large content, use --max-length. The script appends a truncation notice with the next --start-index value.

Requirements

Requires uv on the system. The script uses PEP 723 inline metadata — uv run resolves and caches dependencies automatically (no venv needed).
