Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description bears full responsibility. It discloses that Free is permanent for a single user and paid tiers have a 7-day free trial. It does not mention read-only nature, but the verb 'list' strongly implies it. Lacks details on rate limits or authentication, but the core behavior is well covered.
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?
Two sentences, no wasted words. The first sentence delivers the core purpose and outputs; the second adds critical nuance (free trial, permanent free tier). Information is front-loaded and easy to parse.
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?
Despite no output schema, the description adequately explains what the tool returns: pricing details, discounts, free trial info. It covers the key aspects for a listing tool with two optional parameters. No missing critical information.
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 100%, so baseline is 3. The description adds value by explaining that the response includes 'charged price and a standing list-price anchor per region' and 'volume and annual prepay discounts', which contextualizes the parameters without explicitly repeating their schema definitions.
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 lists HelloTime pricing plans with specific details (charged price, list-price anchor, volume/annual discounts). It names the tiers (Free, Attend, Track, Business) and distinguishes from siblings like feature_search and list_competitors by focusing on pricing.
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 implies usage for retrieving pricing information but does not explicitly state when to use this tool versus alternatives (e.g., country_support for regional support, list_competitors for competitor comparison). No when-not-to-use or exclusion criteria are provided.
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 targets a distinct resource: features, plans, competitors, country support, payroll engines, statutory rates, payment methods, and a free-text search across all of them. There is no overlap in purpose; even feature_search complements the list tools by handling ad-hoc queries.
Tool names are inconsistent: three use a 'list_' prefix (list_competitors, list_features, list_plans), while the rest are noun phrases like 'country_support', 'feature_search', 'local_payment_methods', 'payroll_capabilities', and 'statutory_rates'. There is no uniform verb_noun pattern, making names less predictable.
Eight tools is a well-scoped number for a product information server covering features, plans, competitors, countries, payroll, payments, and rates. Each tool has a clear role and the count is within the ideal range.
The tool surface covers all major categories one would expect for the HelloTime product domain: features, plans, competitor positioning, country-specific support, payroll engines, statutory rates, and payment methods. The feature_search tool further fills gaps by enabling cross-category queries, leaving no obvious dead ends.
