Search LinkedIn posts

linkedin_posts_search_list
Read-only

Search public LinkedIn posts site-wide by keyword (not scoped to one profile or company — use linkedin.profiles.posts.list or linkedin.company.posts.list for that). Returns a list (use cursor when paginated).

Input Schema

TableJSON Schema
NameRequiredDescriptionDefault
qNoAlias for `query`. Prefer `query`.

cursorNoOpaque pagination cursor returned by a previous response.
offsetNoIgnored if this tool does not support it.
contextYesDescribe the user's underlying goal in one sentence — not the tool you are calling.
keywordsNoAlias for `query`. Prefer `query`.
pageSizeNoIgnored if this tool does not support it.
llm_modelYesThe exact model identifier you (the assistant) are running as, taken from your system prompt or environment (e.g. "claude-opus-4-8", "gpt-5.2"). Used for analytics only. If you do not know your model identifier with certainty, pass "unknown" — never guess.

TDQS

A4.4/5.0
Behavior4/5

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

Annotations (readOnlyHint=true, openWorldHint=true) already cover the safety profile and result volatility; the description adds non-scoped site-wide behavior and cursor-based pagination without contradicting annotations. It could go further by disclosing rate limits or what fields each list item contains, but with annotations present this is solid.

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

Conciseness5/5

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

Two tightly written sentences: the core behavior and scope appear first, the alternatives second, and the return/pagination note last. No filler or repetition of schema content.

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

Completeness4/5

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

For a search-list tool with 100% parameter schema coverage and no output schema, the description sufficiently conveys scope, return shape, and pagination. It does not describe the shape of list items, but 'Returns a list' plus cursor guidance is adequate for selecting and invoking the tool.

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

Parameters3/5

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

Schema coverage is 100%, so the schema already documents every parameter. The description adds only a generic 'keyword' and cursor/pagination hint, which maps to `query` and `cursor` but adds little new semantic information.

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'), resource ('public LinkedIn posts'), and scope ('site-wide by keyword'). Explicitly contrasts with profile/company-scoped search, so an agent can tell it apart from linkedin_company_posts_list and similar siblings.

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

Usage Guidelines5/5

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

Gives explicit when-to-use (site-wide keyword search) and when-not-to (profile/company-scoped), naming two alternatives. Adds a pagination note ('use cursor when paginated') that tells the agent how to continue retrieving results. The alternative names use dot notation rather than the sibling naming convention, but the routing intent is unambiguous.

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