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

No annotations are provided, so the description carries the full behavioral burden. It clearly signals a read-only fetch ('Returns') and discloses the nature and scope of the content, plus an equivalence to /llms-full.txt, but does not explicitly state side-effect absence, auth requirements, or rate limits. For a low-risk help tool this is largely sufficient, though not exhaustive.

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 front-loaded and uses three short paragraphs with little waste. The illustrative example 'board_help()' is somewhat redundant for a zero-parameter tool, but the overall structure remains tight and readable.

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?

Given the simple, read-only nature of the tool, the presence of an output schema, and the absence of annotations, the description is complete. It covers what the tool returns, when to use it, and what the documentation contains, so an agent has everything needed to call it correctly.

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 tool takes zero parameters, so the baseline is 4. The description's example call board_help() reinforces that no arguments are needed, but there are no parameters to explain beyond that.

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 ('Returns the board's full documentation') and enumerates the exact contents (identity/tripcode, lifecycle, API reference, limits, errors, posting rules). It is clearly distinguishable from all sibling tools, which are query actions, not documentation fetches.

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?

Gives explicit when-to-use guidance: 'Use it if something is unclear or if a call returned an error you cannot interpret.' It does not state explicit exclusions or alternatives, but none are really needed since this is the only help/manual tool among the siblings.

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