Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description carries the full burden. It reveals that the tool is a 'catalog' (likely read-only) but does not explain any behavior beyond that, such as whether it returns a list, filters by input, or has any side effects. This is minimal disclosure.
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 only one short clause, which is concise, but it sacrifices substance. For a tool with four unrelated parameters and no usage context, this is under-specification rather than efficient brevity; it could be clearer while still being short.
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?
The tool is simple in concept, but with no output schema, no annotations, and four mismatched parameters, the description should clarify how those parameters relate to the HTTP status catalog. It does not, leaving the agent with a vague reference and no guidance on how inputs are used or what result to expect.
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 100% for all four parameters, each with a clear description in the schema. The tool description itself adds no parameter-level detail, but the schema already documents the parameters adequately, so the baseline 3 applies.
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 'Short catalog of common HTTP status codes' uses a noun phrase rather than a verb+resource structure. It does not state what action the tool performs or what an agent can do with this catalog, making it distinct from siblings only by topic, not by function.
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 guidance on when to use this tool versus the siblings (citation, compatibility, normalize-url, validate-json, etc.). The description implies a reference/consultation purpose but does not specify conditions or alternatives, leaving the agent to infer applicability.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Add one secure layer between your agents and this server.
Several tools overlap: citation and normalize-url both decompose URLs into host/scheme, http-200 is a single-code subset of status-catalog, and timezone/utc-time both give current time. compatibility is too vague to position relative to the others, so an agent could easily select the wrong tool.
All names use lowercase-with-hyphens, but the style mixes nouns (status-catalog, timezone), verbs (normalize-url, validate-json), and code-like labels (http-200). There is no consistent verb_noun pattern, though the naming remains readable.
Eleven tools is within a reasonable range for a web/HTTP utility server. However, a few tools could be consolidated (http-200 into status-catalog, utc-time into timezone), so the count is slightly higher than needed but not excessive.
The set covers common status-code lookup, URL parsing, robots.txt inspection, JSON validation, and time retrieval, but it lacks natural complements such as timezone conversion, header inspection, or URL construction. These gaps are workable, but they make the surface feel incomplete for a general HTTP/URL utility tool.
