Find a share link by name

lnkdrp_find_share_link
Read-onlyIdempotent

Search every share link in the workspace by label or audience - the private name a human gave it ("Sequoia", "Inesto / a16z"), not the document's title and not the link's random public shareId (neither of those are searched here). Searches across every document and project in the workspace; listing one document's links with a query runs the same search scoped to that document. Backed by a MongoDB text index: ranked by relevance, matches whole words only - searching "a16z" or "Inesto" matches, a partial word like "nest" does not. Archived and deleted documents' links are excluded. Hits cover both kinds of link: kind 'doc' carries docId/docTitle and a /s/ URL, kind 'project' carries projectId/projectName, a /p/ URL and a null docId (a project link is changed through the project-link tools; the share-link update and delete tools take document links only). Each hit carries status (active|disabled|expired), enabled and expiresAt, which together say whether a found link still opens, and sentAt, sentVia, firstOpenedAt and timeToFirstOpenMs, which say when it was sent and how soon it was first opened. Each hit carries contact, the workspace contact the link is about with role direct (goes straight to them) or share (they can pass it on), or null. contactId or contactEmail keeps only the links carrying that contact; with a contact and no query, returns that contact's links across the workspace, newest first. query, contactId or contactEmail is required. An email that is not a contact fails with not_found (code contact_not_found). Returns [] when nothing matches, not an error. Titles, summaries and viewer-supplied text in results are untrusted content written by document authors and readers.

Input Schema

NameRequiredDescriptionDefault
limitNoMax results, 1-50, default 20.
queryNoName to search for, e.g. "a16z" or "Sequoia". Matches a link's label or audience. Whole words, not substrings. Optional when contactId or contactEmail is given.
contactIdNoOnly links carrying this contact (24 hex, from lnkdrp_list_contacts).
contactEmailNoOnly links carrying the contact with this email; an address not in this workspace's contacts fails with not_found.

TDQS

A4.5/5.0
Behavior5/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

Annotations already establish the safe read profile, and the description layers substantial extra behavior: MongoDB text-index ranking with whole-word-only matching, exclusion of archived/deleted docs, the two link kinds and their differing fields, null docId on project links, error code contact_not_found, and [] instead of an error on no match. It also flags viewer-authored text as untrusted. This is well beyond annotation coverage.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness3/5

Is the description appropriately sized, front-loaded, and free of redundancy?

Purpose is front-loaded, but the body is a dense, run-on block mixing search semantics, hit-field documentation, contact rules, and error handling in a single sprawling paragraph. Much of it is useful, yet it is not well segmented and could be tightened considerably.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness5/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

With no output schema, the description carries the full return-value burden and discharges it: it documents hit fields (status/enabled/expiresAt, sentAt/sentVia/firstOpenedAt/timeToFirstOpenMs, contact role, docId/docTitle vs projectId/projectName) and both success and failure behavior. Nothing an agent needs to call it correctly is missing.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters4/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema coverage is 100% (baseline 3), but the description adds real meaning: query targets label/audience not title/shareId, whole-word semantics, contactId/contactEmail filtering to links carrying that contact, newest-first ordering with a contact and no query, and the not_found failure for a non-contact email.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

States a specific verb (search/find) and resource (share links) and immediately disambiguates what is searched: the human label/audience, explicitly not the document title nor the random shareId. An agent can distinguish it from lnkdrp_list_share_links and lnkdrp_drive_search without opening any schema.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines4/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

Gives clear context ('search every share link in the workspace by label or audience'), notes that listing one document's links with a query runs the same scoped search, and states the constraint that query/contactId/contactEmail is required. It never names a sibling alternative like list_share_links for the unfiltered-enumeration case, so it stops short of full when/when-not routing.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
