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

readOnlyHint=true already declares the safety profile. The description adds useful context by enumerating the returned fields (id, content, should_publish, public link, times) and the underlying endpoint, but says nothing about pagination, ordering, or visibility filtering of unpublished updates.

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?

Front-loads the verb and resource, with the returned fields and endpoint appended efficiently. The 'Sorry: GET ...' endpoint note is a bit terse but not wasteful; overall tightly sized.

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?

With no output schema, the description compensates by listing the returned fields, which is genuinely helpful. It's adequate for a simple two-param read tool, though ordering/pagination behavior is unaddressed.

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 both page_id and notice_id are already documented (including the page_id cross-reference to list_pages). The description adds no syntax or semantics beyond the schema, leaving the baseline of 3 appropriate.

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 ('List') and resource ('updates (timeline comments) of one notice') plus the fields returned. It's clear what the tool does, but it doesn't explicitly differentiate itself from the sibling get_notice_update (single update) or list_notices.

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 'of one notice' phrasing implies usage when you have a notice_id and want its timeline, but there is no explicit when-to-use, when-not, or named alternative (e.g., get_notice_update for a single update). Usage is only inferable.

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