get_block_children

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

No annotations are provided, so the description carries the burden. It discloses the fetch_all default (True, auto-paginate) which is genuinely useful behavioral context. However, it does not state permissions, rate limits, ordering, or what happens with deeply nested children.

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-loaded purpose sentence followed by compact Args and Returns sections. Every line earns its place, though the Args block largely restates the schema titles with little added detail for block_id.

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?

An output schema exists, so return values needn't be detailed, and the description still summarizes them. With no annotations, the description addresses pagination and parameter defaults adequately, though it omits safety/behavioral traits.

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%, so the description must compensate. It documents all four parameters including the fetch_all auto-pagination semantics, which the schema's title 'Fetch All' does not explain. Minor gap: it doesn't clarify page_size interaction with fetch_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?

States a specific verb and resource ('Retrieve children blocks of a block or page') and distinguishes itself from get_block (single block) by targeting children. The 'or page' phrasing is slightly loose but the scope is clear.

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 given on when to use this instead of get_block, get_page, or append_blocks. An agent gets no signal about hierarchy traversal vs single-block retrieval, which matters given the many sibling tools.

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