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

No annotations are provided, so the description carries the full burden. It usefully discloses that the response includes link rows (bank transactions linked to the event), which is real behavioral value, but it says nothing about authorization requirements or behavior when the id is not found. Partial coverage only.

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?

Two compact sentences, front-loaded with the core purpose and followed by the operational hint about where to get the id. No filler.

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?

For a simple single-entity read with no output schema, the description compensates by describing the return composition (link rows) and the ID provenance. Error/failure behavior is unaddressed, but nothing essential for invoking the tool correctly is missing.

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 description coverage is 100% and the single eventId parameter is fully documented (uuid format, pattern, and the 'from list_venture_events' note). The description's reminder of the ID source largely repeats what the schema already states, so the baseline 3 applies.

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?

States a specific verb (retrieve) and resource (venture event) with explicit scope (single, by id), and distinguishes itself from the list sibling by referencing list_venture_events as the ID source. An agent can tell it apart from list_venture_events and the other get_* venture tools without opening a schema.

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?

It implies usage by pointing to list_venture_events for the eventId, which gives a usable workflow hint, but there is no explicit when-to-use vs when-not or statement of what to do instead if the caller wants many events. Usage is implied rather than spelled out.

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