Input Schema

NameRequiredDescriptionDefault
limitNoMaximum records to return (1-100). Each returned record costs one credit.
sinceNoReturn records announced on or after this date (YYYY-MM-DD) or ISO-8601 timestamp.
untilNoReturn records announced on or before this date (YYYY-MM-DD, inclusive) or ISO-8601 timestamp.
cursorNoOpaque pagination cursor returned as pagination.nextCursor on the previous page.
domainNoCompany domain, e.g. stripe.com. Matches the company's primary domain or any domain it redirected from; a full URL works too.
statusNoDeal status filters: announced, completed, or terminated (called off or blocked).
isMergerNoFilter to mergers (true) or acquisitions (false).
companyIdNoReturn only events where this company is the acquirer or target.
countriesNoHeadquarters country codes (ISO alpha-2, OR). Pass "unknown" to include companies with no country on file.
naicsCodeNoNAICS 2022 code for the target (acquired) company. Matches the code and everything beneath it, so "51" also returns 5132 and 5173. Sector ranges work: "31-33" returns all manufacturing. Any 2- to 6-digit code is accepted; codes deeper than we classify (e.g. 541511) match at their deepest classified parent (5415).
verticalsNoTarget company sector filters (OR). Canonical values: ai, fintech, saas, devtools, healthcare, climate, robotics, cybersecurity, logistics, commerce, data, crypto, media, education, marketing, telecom, realestate, hardware, gaming, space.
paymentTypeNoPayment type filters. Canonical values: cash, stock, mixed, undisclosed.
includeTotalNoAlso return pagination.total, the number of records matching these filters across all pages. Costs no credits.
maxAmountUsdNoMaximum deal amount in USD.
minAmountUsdNoMinimum deal amount in USD.
industryGroupsNoCompany industry groups (OR). LinkedIn industry labels, matched case-insensitively; older LinkedIn names and short forms like "software" map to the current label. Pass "unknown" for companies with no industry on file.

A3.5/5.0
Behavior4/5

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

Annotations already declare readOnlyHint=true, openWorldHint=true, and destructiveHint=false, so safety is covered. The description adds meaningful behavioral context by stating results are ordered newest first and that each returned record costs one credit. It does not cover pagination behavior or return shape, but the cost disclosure is a substantive addition.

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?

The description is two efficient sentences: purpose and ordering are front-loaded, then filter coverage and cost are stated compactly. Every sentence adds useful information without repetition.

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

Completeness3/5

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

For a 16-parameter list tool with no output schema, the description is adequate at the invocation level: it states scope, ordering, filter categories, and cost. However, it does not explain pagination behavior or what an acquisition record contains, which would be more important in the absence of an output schema.

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 description coverage is 100%, so the schema already fully documents all 16 parameters. The description summarizes several filters (payment type, deal amount range, merger flag, acquirer/target company) but does not add syntax or interpretation beyond what the schema provides. A baseline 3 is appropriate when the schema carries detailed parameter semantics.

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

Purpose4/5

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

The description gives a specific verb and resource: 'List acquisition and merger events.' It also states ordering, so the agent knows this is a reverse-chronological acquisition/merger search rather than a generic company or funding search. It does not explicitly differentiate itself from sibling tools such as funding_events, which keeps it from a 5.

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

Usage Guidelines2/5

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

The description explains what filters are available and notes the credit cost, but it does not say when to use this tool versus alternatives like funding_events or company_timeline. There are no when-not conditions or explicit routing guidance.

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