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

The annotations already establish that this is a safe, idempotent, closed-world read operation. The description adds a useful domain caveat that channel presence never proves eligibility, supported submission, or publication, which goes beyond the annotations. However, it does not disclose result format, ranking behavior, or how results are limited.

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 efficient: the first sentence states the purpose, the second adds an important caveat, and the third points to documentation. Every sentence contributes value, though it could be more specific about parameters without becoming bloated.

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 search tool with four parameters, no output schema, and no schema descriptions, the definition is under-specified. It does not explain how to choose a source, what query matches, what limit does, or what the results look like, so an agent has significant gaps when invoking 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?

With 0% schema description coverage and four optional parameters, the description only clarifies the idea of a "gap" and loosely gestures at resource types. It does not explain the source enum values (launchbuddy, launchready, agentready, swarm), the meaning of query, or how limit controls result size, so most parameter semantics remain undocumented.

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 and resource set: finding public LaunchBuddy guides, free tools, skills, and launch channels. The scope is narrowed to "a specific gap," so the agent can tell what the tool retrieves. It does not explicitly differentiate itself from siblings like get_launch_resource, which keeps this from a 5.

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?

Usage is only implied by "for a specific gap"; there is no explicit when-to-use guidance, no exclusions, and no mention of alternatives such as get_launch_resource. An agent must infer the routing decision from the tool name and purpose alone.

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