Name	Required	Description
`url`	No	Public Facebook Events explore URL for a city.
`link`	No	Alias for `url`. Prefer `url`.

`time`	No	Optional time window for events.
`trim`	No	Ignored if this tool does not support it.

A3.9/5.0

Behavior4/5

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

The annotations already declare readOnlyHint and openWorldHint, so the description is not required to repeat that. It adds the pagination hint ('use cursor when paginated'), which is useful behavioral context beyond the structured data. It does not mention rate limits or auth, but given the annotations cover safety, this is sufficient.

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 a single, well-structured sentence that front-loads the primary purpose and immediately states the return type and pagination behavior. Every word earns its place, with no redundancy or filler.

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 tool with 19 parameters and no output schema, the description is sparse but adequate for the core use case: it identifies the main input (URL) and the pagination mechanism. It does not explain the content of the returned list or any caveats about the explore URL, but given the schema fully covers parameters and annotations cover safety, it is minimally complete. More detail about the return structure would improve it, but it is not critically incomplete.

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 fully documents all parameters. The description adds no additional parameter semantics beyond what the schema already provides. It mentions the 'explore URL' but that is also in the schema. Thus, the description adds minimal value over the schema, which is the baseline for full coverage.

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?

The description clearly states the verb 'List' and the resource 'Facebook events for a city by explore URL', which distinguishes it from siblings like facebook_events_search_list (search) and facebook_event_get (single event). The scope is explicit.

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

Usage Guidelines3/5

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

The description implies usage when a city explore URL is available, but does not explicitly state when to use this versus alternative tools like facebook_events_search_list or facebook_profile_events_list. No exclusion criteria are given, so an agent must infer the appropriate context.

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