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

With no annotations, the description carries the full burden, and it does add one genuinely valuable behavioral caveat: channel presence never proves eligibility, supported submission, or publication, which prevents the agent over-trusting results. However, it omits other important traits such as read-only nature, result ordering/ranking, default page size, and what the returned items look like.

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?

Two tight sentences with the primary action front-loaded and the caution appended, no filler or restated field names. The second sentence is slightly cryptic in isolation ('Channel presence never proves...') but is still short and purposeful.

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 four-parameter, unannotated, output-schema-less search tool, the description leaves major gaps: no indication of what a result item contains, how guides/skills/channels differ in shape, how 'query' interacts with the enum 'gap' filter, or any default for 'limit'. An agent would need to guess several behaviors before calling it confidently.

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%, so the description must compensate for all four parameters and largely does not. It gestures at 'gap' via 'a specific gap' and loosely at 'source' via the listed resource types, but never explains the ten gap values, what each of launchbuddy/launchready/agentready/swarm contains, the meaning or default of 'limit', or the role of 'query' versus 'gap'.

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 ('Find') plus a concrete resource set ('public guides, skills, and Swarm launch channels') scoped to 'a specific gap', so an agent knows this is a discovery/search tool rather than a fetch-by-id tool. It does not explicitly name how it differs from the adjacent get_launch_resource sibling, which is the only reason it falls short of 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: 'for a specific gap' suggests calling it after a gap has been identified, but there is no explicit when-to-use, when-not-to-use, or named alternative (e.g. get_launch_resource for a known resource). The second sentence is result-interpretation guidance rather than selection guidance, so the agent must infer routing.

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