Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare readOnlyHint=true, idempotentHint=true, and destructiveHint=false, covering the safety profile. The description adds the behavioral detail that the tool tests reachability, but it does not elaborate on what happens if unreachable or what the output represents. With annotations present, a score of 3 is appropriate.
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, clear sentence that directly states the purpose. It contains no unnecessary words and is front-loaded with the action and subject.
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 health check tool with no parameters, strong annotations, and an output schema (not shown but present), the description provides sufficient context. It does not need to explain return values because the output schema covers that.
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?
The tool has zero parameters, so the baseline is 4. The description does not need to add parameter details, and the empty input schema already fully describes the parameter surface.
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 function: checking whether an MCP-compatible client can reach KimchiSushi. It uses a specific verb ('check') and resource ('KimchiSushi'), and it is distinct from sibling tools like fetch, search, or get_recent_posts, which 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 conveys that this is a health/connectivity check, so the usage context is implied. However, it does not explicitly state when to use this tool versus alternatives or provide any exclusion criteria, such as 'use this before other calls to verify connectivity.'
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 are clearly distinct (search, recent posts, health check, routing), but fetch and get_post_with_comments both retrieve posts, differing only by id type and whether comments are included. This overlap could cause misselection, though the descriptions help.
Naming styles are mixed: bare verbs (fetch, search), get_ prefixed names (get_post_with_comments, get_recent_posts), and a long noun-like name (get_kimchisushi_agent_entrypoints). The inconsistent use of verbs and prefixes makes the pattern unpredictable.
With 6 tools, the server is well-scoped for a read-only content access service. Each tool serves a clear purpose without redundancy or excessive sprawl.
The tool surface covers the core lifecycle for the domain: searching, fetching individual items, listing recent items, and routing to relevant areas. No obvious gaps for a read-only information retrieval service.
