## Tools (as reported by the server, not verified)

- `search\_lacuna`: Search Lacuna's ML/AI corpus for papers, research directions, authors, venues, institutions, novel research hypotheses, and research resources \(code repositories, datasets, models, and demos linked to papers\). For novel ML/AI research ideas, use search\_type="hypothesis", then get\_hypothesis on promi
- `get\_hypothesis`: Fetch a generated novel ML/AI research proposal from Lacuna. Use after search\_lacuna\(search\_type="hypothesis"\) to inspect a proposal. view selects the response shape: - "context" \(default, recommended\): compact single-fetch proposal context — summary\_markdown, abstract, and linked directions, with t
- `get\_direction`: Fetch a Lacuna research direction/cluster. Use a numeric cluster ID \(for example 25005\) or a direction URL ending in that number. view selects the response shape \(\`context\` typically contains the fields \`full\` provides plus the agent-oriented summary content\): - "context" \(default, recommended\): com
- `get\_direction\_papers`: Fetch paginated papers associated with a Lacuna research direction/cluster. view selects the per-paper shape: - "compact" \(default, recommended\): citation-ready rows \(id, url, title, year, venue, a few authors, abstract snippet\). Drops the raw upstream info blob and levels.cluster internals that oth
- `get\_paper`: Fetch a Lacuna paper by artifact id or paper URL. include\_resources adds linked resources \(code repositories, datasets, models, and demos\) in context and full views by default. Pass False to omit them; other views ignore this option. Pass a resource entry's id to get\_resource for further details. vi
- `get\_resource`: Fetch a Lacuna research resource \(code repository, dataset, model, or demo\). Accepts a resource artifact ID \(art\_...\) or a Lacuna resource URL containing that ID \(/resource/\<slug\>/art\_...\). The response includes the external url, a summary, facets \(tasks, modalities, size, license, access\), provider
- `get\_author\_papers`: Fetch one page of an author's papers, ordered from newest to oldest.
- `get\_author\_directions`: Fetch one page of an author's named research directions.
- `get\_author\_context`: Fetch agent-oriented context for a Lacuna author. Author profiles describe research output \(papers, directions, impact\). A free-text \`affiliation\` field may be present but can be incomplete or outdated and may not represent current employment; the corpus has no biography or employment history, so do
- `get\_author\_neighbors`: Fetch one ranked page of neighboring/similar Lacuna authors.
- `get\_venue\_context`: Fetch agent-oriented context for a Lacuna venue, optionally scoped to a year. Venue keys are opaque hashes \(e.g. "d7bf22905bd6"\), never human-readable names like "icml". Find the key first via search\_lacuna\(search\_type="venue"\) or pass a /venue/... page URL. view selects the response shape: - "conte
- `get\_institution\_context`: Fetch agent-oriented context for a Lacuna institution. view selects the response shape: - "context" \(default, recommended\): compact institution context — capped top authors with the duplicated institution block dropped server-side. - "full": the complete institution context shape \(duplicated institu
- `get\_institution\_authors`: Fetch one page of authors affiliated with a Lacuna institution. Results are ordered by paper count. Use authors\_total, authors\_returned, authors\_offset, and authors\_truncated to page through the complete list.
