Web Summary Skill
Single-URL content summarisation and topic extraction via the web-summary
subcommand of agentbox-mcp — a single Rust rmcp binary
(services/agentbox-mcp) that also serves the imagemagick and
gemini-url-context skills. It replaces the former Python FastMCP server
one-for-one, including its own direct YouTube transcript fetch (watch page +
timedtext, no youtube-transcript-api dependency). It fetches the page (or
YouTube transcript) and summarises it through the Ontology Loom facade — the
load-bearing, model-swappable LLM door (agentbox ADR-051). The former Z.AI
service on port 9600 is retired; see references/architecture.md.
When to use
- Summarise one web article, blog post, or documentation page
- Extract and summarise a YouTube video transcript
- Generate semantic topic links for note-taking in the vault (Obsidian)
- Produce short, medium, or long summaries; extract key concepts from text
When not to use
- Interactive browser automation (clicking, filling forms, live scraping) — use the
browserorplaywrightskills. - Multi-URL comparison or structured data extraction from URLs — use
web-researcher(scrape_page/search_and_scrape) or thebrowsersidecar for JS-rendered pages. - Broad, multi-source web search with citations — use
perplexity-researchorweb-researcher. - Content you already have as local text — summarise it directly without this pipeline.

Examples
# Summarise a web article
summarize_url({
"url": "https://example.com/article",
"length": "medium",
"include_topics": True,
"format": "obsidian"
})
# Get a YouTube transcript
youtube_transcript({"video_id": "dQw4w9WgXcQ", "language": "en"})
# Generate topic links
generate_topics({"text": "Your text content here...", "max_topics": 10, "format": "obsidian"})
Output formats
obsidian is the default (ADR-2028 D4) and emits - [[Topic]] wiki-links
ready to paste into a vault page; plain emits - Topic.
logseq is legacy: it is still selectable and emits the identical
- [[Topic]] wiki-link syntax, but it is retained only for callers pinned to
the old name and should not be used in new work. Pages this skill's output
lands in carry V2 YAML frontmatter — see project/docs/VAULT-corpus-format.md
