Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare readOnlyHint, idempotentHint, and destructiveHint. The description adds value by specifying 'aggregate read-only' and detailing the exact metrics returned, which provides context beyond the annotations.
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?
Single sentence that is front-loaded with the key action ('Fetch aggregate read-only registry stats') and includes specific details. No unnecessary 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?
Given no parameters and presence of output schema, the description adequately explains what the tool returns. It covers the key aspects without needing further elaboration.
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?
There are no parameters, so schema coverage is 100% by default. The description adds meaning by listing the types of data included in the response, compensating for the lack of parameters.
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?
Description clearly states the verb 'Fetch' and the resource 'aggregate registry stats', listing specific metrics like freshness, category counts, and coverage. This distinguishes it from sibling tools such as 'registry.info' and 'registry.list', which likely serve different purposes.
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 does not explicitly provide when-to-use or when-not-to-use guidance relative to other sibling tools. Usage is implied for aggregate statistics, but no alternatives or exclusions are mentioned.
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.
Most tools have distinct purposes, especially with clear prefixes. However, there is some overlap between entry.safety and entry.trust (both deal with safety/trust metadata), and between registry.recommend and registry.plan (both provide recommendations). The descriptions help differentiate but some ambiguity remains.
All tool names follow a consistent pattern: a domain prefix (entry, install, registry, submission) followed by a descriptive noun, all lowercase with underscores. This makes the surface predictable and easy to navigate.
27 tools is slightly high but reasonable given the broad scope of the HeyClaude registry, which includes browsing, recommending, installing guidance, and submission preparation. The count is appropriate for the server's purpose.
The tool surface is comprehensive, covering search, detail, comparison, safety/trust analysis, install setup for multiple clients, recommendation, and a full submission pipeline (validation, review, schema, etc.). There are no obvious gaps for the intended read-only registry directory functionality.
