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

No annotations are provided, so the description carries the full burden of behavioral disclosure. It states what data is returned but does not disclose whether this is a read-only operation, whether the slug must be URL-encoded, what happens if the slug is not found, or any rate limits. For a simple read tool, the lack of error/not-found behavior and response format details is a notable gap.

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 a single, information-dense sentence. It front-loads the core purpose ('Full indexed detail for one project by slug') and then lists the included fields. No wasted words.

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 single-parameter read tool, the description covers the main purpose and return contents. However, with no output schema and no annotations, it lacks details on error behavior, response format, and slug semantics. It is adequate but not complete for an agent that needs to handle edge cases.

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 the single 'slug' parameter. The description says 'by slug' but does not explain what a slug is, how it should be formatted, or where to find it. It adds minimal meaning beyond the schema's bare 'slug' string property.

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 states the tool's purpose: retrieving full indexed detail for one project by slug, and enumerates the specific fields included (ownership, builtBy, canonical URL, links, proof count). This distinguishes it from sibling tools like list_projects (which presumably lists projects) and get_proof (which fetches a proof).

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?

The description implies usage: call this when you need full detail for a single project identified by slug. It does not explicitly state when to use alternatives like list_projects or get_profile_summary, nor does it mention any exclusions or prerequisites. The context is clear enough for a single-project lookup, but no explicit routing guidance is provided.

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