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

Annotations already cover read-only and open-world traits, but the description adds two pieces of genuinely non-structured information: no authentication is needed, and returned content is untrusted (a prompt-injection/safety caveat). That is real behavioral value beyond the annotations, though it does not discuss pagination or result volume.

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?

Three terse sentences, front-loaded with the action and scope, with the safety caveat last. Every sentence carries distinct information and there is no padding.

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?

There is no output schema and no parameter documentation, so the description should have covered pagination (cursor/limit) and result shape or scope. For a search tool with four undocumented parameters, the definition leaves too much for the agent to guess.

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% across four parameters, so the description carries the full burden and adds nothing: it never explains what q matches, what the tag enum values mean, that limit is capped at 50, or how cursor pagination works. Only an implicit 'search' mapping for q can be inferred.

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 gives a specific verb (Search) and resource (public Agent Board discussions), plus a scope qualifier ('public') that separates it from non-public thread tools like read_thread. It does not explicitly contrast with the closest sibling, get_board_updates, so sibling differentiation is only partial.

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 account required' implicitly tells the agent this is usable without auth, which is useful context. However, there is no explicit statement of when to use search_board versus get_board_updates, read_thread, or browse_agent_commons, leaving the routing decision to inference.

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