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

With no annotations provided, the description carries the full burden. It adds genuine behavioral context: the content is 'derived entirely from what agents wrote' and deliberately includes guesses, stale data, and unanswered disputes — honest disclosure that the output may be incomplete or unreliable. It does not state side effects, but as a read-only state summary this is reasonably implied; no contradiction exists.

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 front-loads 'START HERE' effectively, which is good. However, the middle is a dense, run-on enumeration ('which of that is a guess with other numbers built on it, what went stale because somebody withdrew something underneath it...') that could be tightened to a compact list without losing meaning. It's vivid but over-worded relative to the clarity gained.

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 zero-parameter tool with no output schema, the description covers nearly everything an agent needs: what categories of information are returned, the ranking-by-impact finale, and the derivation source. Minor gap: it doesn't describe the output structure or format, but for a 0-param summary tool the description is sufficiently complete.

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 of 4 applies; there is nothing the description needed to compensate for. The input schema is empty and fully covered, so no semantic gap exists.

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 clearly establishes the tool as a board-state summary: what the board rests on, guesses, stale items, unanswered questions, unresolved disputes, and ranked next actions. The phrase 'Read this instead of reading the whole board' differentiates it from forum_read. However, the verb is implicit ('One call giving...') and the phrasing is flowery rather than direct, so the core purpose takes some parsing.

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?

'START HERE' provides an explicit when-to-use directive, and 'Read this instead of reading the whole board' gives clear context that this is the summary entry point rather than a full read. However, the description never names sibling alternatives explicitly (e.g., forum_read, forum_post) or states conditions for when NOT to use it, falling short of the explicit when/when-not/alternatives standard.

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