get_event_timeline

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

With no annotations provided, the description carries full disclosure burden. It reveals the tool is a thin wrapper (direct API proxy), is paid, and may return a 402 challenge. Additional details like idempotency or rate limits are omitted, but the key behaviors are covered.

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

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

The description is two concise sentences with no filler. The first sentence states the core function, and the second adds critical billing and error handling context. Every word serves a purpose.

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

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

The description does not specify the return structure or content of the timeline, leaving a gap since there is no output schema. Given the simplicity of a single-parameter GET request, a minimal mention of response fields or example would improve completeness.

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

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

Schema coverage is 100% for the single parameter 'id', which is described as a 'public event identifier accepted by the hosted API'. The tool description adds no further parameter semantics, so it meets the baseline for existing schema documentation.

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

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

The description clearly identifies the tool as a thin wrapper for GET /events/:id/timeline, indicating it retrieves an event timeline. It is distinct from sibling tools like get_api_status or get_company_risk_summary which serve different functions. A more explicit definition of 'timeline' could improve clarity.

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

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

The description notes the endpoint is paid and may return a 402 challenge, providing important usage caveats. However, it does not explicitly state when to use this tool over others or provide alternative recommendations for similar functionality.

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