Coverage — what this server can and cannot verify

coverage
Read-onlyIdempotent

What this server covers: deals and loans against the universe, the field inventory with full bound definitions, counterparty roles, current-only scope, and dual-sourced agreement stats (single-source reported separately). Call before reading an UNVERIFIED as meaningful. Contact cairn@cmdrvl.com for deeper coverage, history, bonds, entitlements.

TDQS

A4/5.0
Behavior4/5

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

Annotations already cover read-only, idempotent, closed-world behavior, so the bar is lower. The description adds valuable limits beyond annotations: current-only scope, dual-sourced agreement stats with single-source reported separately, and an explicit note that deeper coverage, history, bonds, and entitlements require contact. That is meaningful behavioral context.

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

Conciseness4/5

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

The description is compact and front-loads the coverage scope before the call guidance. The list of covered domains is dense but each item earns its place; nothing is redundant. It is slightly terse in structure rather than wasteful.

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

Completeness4/5

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

Given that this is a zero-parameter meta tool with an output schema, the description provides enough context to understand what the tool returns and when to invoke it. The main missing element is explicit sibling routing—telling the agent when to use verify_* instead—but the core completeness is strong.

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

Parameters4/5

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

With zero parameters and 100% schema description coverage, there is no parameter semantics to document. Baseline for a no-parameter tool is 4, and the description correctly does not waste space on nonexistent inputs.

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

Purpose4/5

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

The description states a specific purpose—documenting what the server covers (deals, loans, field inventory, counterparty roles, agreement stats)—which is clearly distinct from the verify_* and find_* siblings. It does not explicitly name those siblings or say 'not for X', so it stops short of full differentiation.

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?

It gives an explicit usage trigger: 'Call before reading an UNVERIFIED as meaningful.' That is a clear when-to-use condition. It does not name alternatives or state when not to call it, but for a meta-coverage tool the primary routing instruction is present.

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