Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description must fully disclose behavioral traits. It only states that a URL is returned, but does not mention any side effects, creation of state, authentication requirements, or rate limits. The name suggests creation, but the description omits any creation semantics.
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 sentence, which is concise but too brief given the complexity of the tool (4 parameters, no schema descriptions). It front-loads the purpose but omits necessary details about parameters and behavior, making it under-specified for effective use.
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?
With 4 parameters, no output schema, and no annotations, the description is incomplete. It does not explain the function of the parameters, the format of the returned URL, or any behavioral implications. The agent lacks enough context to use the tool correctly without external knowledge.
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%, meaning no parameter descriptions exist in the schema. The tool description adds no information about the four parameters (sku, locale, agentSource, destination). It does not explain their meaning, usage, or how they affect the output, leaving the agent with no guidance.
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 that the tool returns a Simsima product URL with agent attribution for checkout. It uses a specific verb ('Return') and identifies the resource ('product URL'). This distinguishes it from sibling tools that deal with plans and destinations.
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?
No guidance is provided on when to use this tool versus alternatives. There is no mention of prerequisites, when not to use, or which scenarios require this tool. The description is purely functional with no contextual usage advice.
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.
Each tool has a clear primary purpose, but check_coverage and get_destination_info both provide coverage-related information, and recommend_plan/search_plans can overlap in plan selection. Descriptions are detailed enough to guide an agent, though a few boundary cases remain.
All tool names follow a consistent verb_noun pattern: check_, create_, get_, list_, recommend_, search_. The verbs are distinct and the nouns clearly identify the resource being acted on.
Seven tools is well-scoped for an eSIM connectivity server, covering coverage, destination info, plan discovery, recommendation, and checkout without unnecessary duplication.
The tool set covers coverage checks, destination details, plan search/retrieval, recommendations, and checkout handoff. Minor gaps exist around top-up actions and post-purchase order management, but the core connectivity workflow is well covered.
