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

No annotations are provided, so the description carries the full behavioral burden. 'Get details' implies a read-only lookup and the enumeration of returned fields describes the payload, but there is no disclosure of auth requirements, rate limits, or failure behavior (e.g., unknown slug) for a tool that takes an externally sourced identifier.

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?

One front-loaded sentence with a bracketed category tag, then the essential payload list — nothing redundant. It is appropriately sized for a single-parameter lookup, though the tag prefix is mild structural noise.

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 simple read-only lookup with no annotations and no output schema, the description compensates by enumerating the returned fields, which is what the agent would otherwise lack. It leaves only minor gaps around error behavior and the slug format.

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 coverage is 0% for the single 'slug' parameter, and the description only adds its provenance ('from search_tools'). It does not state the expected slug format or that the value must come from a prior search result — useful, but partial compensation for a fully undocumented parameter.

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 and resource ('Get details for one tool by slug') and enumerates exactly what is returned (GitHub stats, capabilities, best-for, limitations, alternatives). It also distinguishes itself from search_tools by naming it as the source of the slug, so an agent can tell the lookup apart from the sibling search tool.

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 parenthetical '(from search_tools)' implies the usage pattern: call search_tools first, then drill into one result. However, it never says when NOT to use this tool, nor does it route to the close sibling get_alternatives even though 'alternatives' is listed as returned data — an overlap the agent must resolve by inference.

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