List HelloTime features (shifts, rosters, leave types, timesheets, time tracking, productivity, GPS / geofence, biometric kiosk, payroll, invoicing, analytics, projects, reports, integrations).
| Name | Required | Description | Default |
|---|---|---|---|
| plan | No | Only return features available in this plan tier. | |
| category | No | Filter to one feature category (shifts, rosters, leave, timesheets, gps-geofence, biometric-kiosk, etc.). |
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description carries the burden of behavioral disclosure. It accurately describes a read-only listing operation with optional parameter filtering. However, it does not disclose return format, potential pagination, or error behavior, which would be helpful for a tool with no output schema.
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, well-front-loaded sentence that efficiently lists the feature categories. It wastes no words, though the list is long and could benefit from a brief summary phrase before enumeration.
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 the tool's simplicity (2 optional enum parameters, no output schema, no nested objects), the description is reasonably complete. It covers the core purpose and the breadth of what is listed. However, for a tool that might support multiple plan tiers, it could explicitly state that the full list is returned when no plan is specified.
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% and all parameters have enum constraints with descriptions. The tool description reiterates the feature list already in the schema, adding no new semantic detail beyond what's in the schema. Baseline 3 is appropriate.
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 features and provides an exhaustive enumeration of feature categories. It effectively distinguishes from siblings like list_plans or feature_search by indicating this is a broad listing of all available features.
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 that this tool is for retrieving a list of feature categories, but does not explicitly contrast with sibling tools like feature_search or list_competitors. However, the sibling tool names suggest different purposes, so a clear usage context is inferable but lacks explicit when-not-to-use guidance.
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.
