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

With no annotations present, the description carries the full burden, and it does disclose one real behavior: unpublished entries are excluded from results. However, it says nothing about pagination behavior despite a 'page' parameter, result ordering/relevance, result count limits, or authentication requirements — all material for a 4-parameter search tool.

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 short sentences, with the core scope (what corpus is searched) front-loaded ahead of the result-scope caveat. Nothing is redundant. It is efficient, though it spends its brevity on scope rather than on operationally useful 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?

For a 4-parameter, no-annotation, no-output-schema tool, the description omits filtering semantics, pagination, and result format. An agent knows what the tool searches but not how its filters compose or what a response looks like — significant gaps given zero structured behavioral metadata.

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 only 25%: only 'query' is documented in the schema, while 'tag', 'page', and 'category' (which has an enum) have no descriptions. The description adds no information about any of them — not whether tag and category can be combined, whether query matches tags, or how paging behaves — so the coverage gap is left fully unaddressed.

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?

States a specific verb (search) and a specific resource (the PostLaunchKit directory of human-reviewed free tools/projects), scoping it to published entries. It is clearly distinguishable from get_project, which implies retrieval of a single entry. It stops short of naming siblings like list_categories or explaining how that differs from this search.

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 statement of when to use this tool versus get_project, list_categories, or list_launch_directories, and no prerequisite or exclusion guidance. The only hint — 'Returns published entries only' — describes result scope, not invocation conditions. The agent must infer usage entirely.

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