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

Annotations already declare the safety profile (readOnlyHint, idempotentHint, destructiveHint=false, openWorldHint). The description adds that the report is curated/edited from dailies and grouped by section, which sets expectations about coverage and shape, but says nothing about auth, rate limits, or freshness/latency of the underlying data.

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 sentences, no filler: the content summary comes first and the usage/default rule follows. Every clause carries information an agent needs to select and call the tool.

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 single-optional-parameter read tool with rich annotations and no output schema, the description covers what the tool returns conceptually and how the default resolves. Missing only peripheral detail such as how sections are enumerated or how much history is available.

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?

There is one optional parameter with 100% schema description coverage, including the YYYY-MM pattern and the omit-for-latest behavior. The description merely restates the omit-month default and adds no format or boundary detail beyond the schema, 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?

The description names a concrete verb and resource ("Get AIHOT's edited monthly report") and characterizes the content: the month's most important events drawn from its dailies, grouped by section, with an overview. That implicitly separates it from aihot_get_daily/aihot_get_weekly, though it never names those siblings explicitly.

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 states the use case directly ("Use this for what happened this month or in a given month") and gives the default-selection rule ("omit month for the latest"). It lacks explicit exclusion guidance such as when to prefer aihot_get_weekly or aihot_get_daily instead.

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