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

With no annotations provided, the description carries the full burden of behavioral disclosure. It states it's a read operation ('Get'), implying safety, but lacks details on authentication needs, rate limits, error handling (e.g., invalid ID), or response format. For a tool with zero annotation coverage, this leaves significant gaps in understanding its behavior.

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 a single, front-loaded sentence with zero waste—it directly states the tool's purpose without unnecessary words. Every part of the sentence ('Get a specific time entry by ID') contributes essential information, making it highly efficient and easy to parse.

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?

Given no annotations and no output schema, the description is incomplete for a tool with parameters. It doesn't explain return values, error conditions, or behavioral traits like idempotency. While the purpose is clear, the lack of context for usage and behavior makes it inadequate for safe and effective tool invocation by an AI agent.

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%, so the schema fully documents both parameters (id and expand). The description adds no additional meaning beyond implying 'id' is required for retrieval, which is already clear from the schema. Baseline 3 is appropriate as the schema does the heavy lifting, but the description doesn't compensate with extra context like examples for 'expand'.

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 states the action ('Get') and resource ('a specific time entry by ID'), making the purpose immediately understandable. It distinguishes this from sibling tools like 'get_time_entries' (plural) by specifying retrieval of a single entry via ID. However, it doesn't explicitly contrast with other 'get_by_id' tools (e.g., get_contact_by_id), which slightly limits differentiation.

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 provides no guidance on when to use this tool versus alternatives. It doesn't mention sibling tools like 'get_time_entries' for listing multiple entries or clarify prerequisites (e.g., needing a valid time entry ID). Usage is implied from the name but not explicitly stated.

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