get_hours_entry

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 states it's a read operation ('Get'), but doesn't disclose behavioral traits such as authentication requirements, error handling (e.g., invalid ID), rate limits, or what happens if the entry doesn't exist. The description is minimal and lacks necessary context for safe invocation.

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 concise with a single sentence 'Get specific hours entry by ID', which is front-loaded and wastes no words. However, it's arguably too brief, bordering on under-specification, but within the bounds of efficient communication.

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 the tool's complexity (simple retrieval), no annotations, no output schema, and 0% schema coverage, the description is incomplete. It doesn't explain return values, error cases, or operational context, leaving significant gaps for an AI agent to understand how to use it effectively.

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 0%, with one parameter 'hours_id' undocumented in the schema. The description adds minimal meaning by specifying 'by ID', but doesn't explain what 'hours_id' is (e.g., format, source, uniqueness) or provide examples. It partially compensates for the coverage gap but insufficiently for a tool with a required parameter.

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 'Get specific hours entry by ID' clearly states the verb ('Get') and resource ('hours entry'), but it's vague about what 'hours entry' represents (e.g., time tracking record, work log). It distinguishes from sibling 'get_hours' (plural) by specifying 'by ID', but doesn't fully differentiate from other retrieval tools like 'get_task' or 'get_project' in purpose.

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?

No guidance is provided on when to use this tool versus alternatives. It doesn't mention prerequisites (e.g., needing a valid hours_id), when not to use it (e.g., for bulk retrieval), or direct alternatives like 'get_hours' for listing entries. The description implies usage for single-entry retrieval but lacks explicit context.

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