TDQS

A4.1/5.0
Behavior4/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

Annotations already declare read-only, idempotent, and non-destructive behavior. The description adds valuable context about the result limit and the behavior when search is omitted.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness3/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The core description is concise, but the long-form repeats the same information with a heading and parameter section, introducing redundancy.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness5/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a simple read-only lookup with one optional parameter, the description fully covers purpose, usage, behavior, and parameters. No output schema is needed for this straightforward tool.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema coverage is 100%, so the schema already documents the search parameter. The description repeats the same meaning without adding new semantic details.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states the tool searches US telephone area codes by code number or state name. The verb 'Search' and specific resource distinguish it from sibling tools like fetch_zipcodes and fetch_states.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines4/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

Provides clear context: omit search to get all area codes, and returns up to 10 results. It doesn't explicitly mention alternatives, but the resource scope is self-evident.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

A3.6/5.0
Disambiguation4/5

Most tools follow a clear resource+action pattern (fetch_* for lists, get_* for single items, create/update/delete for writes), making them distinguishable. A few near-overlaps exist (fetch_billing_transactions vs fetch_wallet_transactions, draw_winners vs schedule_drawing) but the descriptions clarify the boundaries.

Naming Consistency4/5

Tool names consistently use snake_case verb_noun, with fetch_ for list operations and get_ for single-item retrieval. Some verb variation (add_participant, count_participants, draw_winners, schedule_drawing) deviates from the dominant create/fetch/update/delete pattern but remains predictable and readable.

Tool Count1/5

With 83 tools, this is far beyond a well-scoped server (typically 3-15, with 25+ considered too many). Even though the platform has broad functionality, the sheer number of tools creates significant agent confusion and selection overhead.

Completeness4/5

The sweepstakes domain is thoroughly covered: lifecycle management, participants, groups, rules, drawings, winners, calendar, notes, todos, tickets, surveys, invoices, billing, files, and entry settings. A few minor gaps exist (e.g., no general participant field update, no archive action) but the surface is remarkably complete for its scope.
