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

Annotations already declare readOnlyHint=true, so safety is covered; the description usefully discloses that category and a type discriminator (opening/closing) come back, which annotations don't say. It adds no information about pagination defaults, ordering, or whether the list is scoped to the authenticated account only.

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?

One front-loaded sentence that states the resource and the returned shape, followed by the endpoint. The endpoint fragment is arguably filler since it restates nothing an agent can act on, but there is no real bloat.

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 low-complexity, zero-required-parameter list tool with no output schema and fully covered params, the description supplies enough: what is listed, what fields come back, and the read-only nature. The missing piece is disambiguation from the proposal-scoped sibling listing.

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?

Both parameters (page, per_page) are already fully documented in the schema at 100% coverage, including defaults and the 100 max, so the baseline is 3. The description contributes nothing about paging semantics, such as whether the section list is short enough to need paging at all.

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?

Specific verb plus resource: 'List the reusable content sections saved on the account', and it even names the returned attributes (category and type: opening or closing). It's clear what the tool does, but it never distinguishes itself from the close sibling bidsketch_list_proposal_sections (sections attached to a proposal vs. the account-level library), which is the one differentiation an agent actually needs here.

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?

There is no when-to-use guidance: no statement of what it's for (browsing a content library before adding a section to a proposal), and no mention of when to use bidsketch_list_proposal_sections or bidsketch_get_section instead. The 'GET /sections.json' fragment implies a read but adds nothing about selection.

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