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

No annotations are supplied, so the description carries the full behavioral burden and mostly fails it: nothing about permissions, side effects, output format, or limits. The only substantive claim is that the pack 'includes the complete prompt, usage guide, and edge-case handling', which hints at packaged prompt content but reads as promotional copy rather than a behavioral disclosure.

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 sentences, none of which front-loads the actual function; the lead sentence is an abstract slogan. The wording is compact but wasted on sales language ('professional results in minutes') instead of operational detail.

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?

With no annotations, no output schema, and four confusable siblings, the definition should explain what a 'board' artifact is and how it differs from analyze/diag/formula/tpl. It delivers none of that, leaving the agent without enough information to invoke the tool 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?

There is a single optional parameter with 100% schema description coverage ('Optional user query to scope the analysis'), so the schema already carries the meaning. The description adds nothing about the query parameter — not its format, not what scoping does — so baseline 3 applies.

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 never states a concrete verb+resource for the operation; 'Turn expertise into output' and 'prompt pack' are marketing framing, not a description of what the tool does with a funnel. It does not distinguish itself from the four sibling funnel tools (funnel-analyze-tool, funnel-diag-tool, funnel-formula-tool, funnel-tpl-tool), so an agent cannot tell which funnel variant to pick.

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, when-not-to-use, or alternative-tool guidance anywhere in the text. With five near-identically named funnel siblings, the absence of any routing guidance is actively harmful rather than merely missing.

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