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

With no annotations, the description must disclose behavioral traits. It only indicates the action (view total hours) but does not mention side effects, authentication needs, rate limits, or whether it's read-only. The implied read-only nature is insufficient for transparent behavior disclosure.

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 extremely concise: one sentence for purpose, then a minimal two-line parameter list. Every sentence adds value, with no redundancy or filler. It is front-loaded with the core 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?

For a simple aggregated query with two required parameters and an output schema, the description is nearly complete. It covers the purpose and parameter format. Since the output schema exists, the lack of return-value description is acceptable. Minor gap: no mention of behavior if from_date > to_date.

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?

The description adds format guidance ('YYYY-MM-DD') for both parameters, which the schema lacks (no description). However, it omits details like inclusivity of dates, order validation, or range bounds. With schema coverage at 0%, this moderate addition earns a 3.

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 ('Xem tổng giờ đã log' – view total logged hours) and the resource (time logs in a date range). It differentiates from siblings like 'get_today_logs' (single day) and 'log_time' (logging), making the tool's scope unambiguous.

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 (e.g., 'get_today_logs' for today's logs) or when not to use it. The description merely states what it does, leaving the agent without decision support for tool selection.

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