A3.6/5.0

Behavior3/5

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

Annotations already declare readOnly=true, idempotent=true, destructive=false and closedWorld=false, so safety is covered. The description's only added behavioral fact is that it operates on already-saved collection members rather than discovering new ones; it says nothing about ordering tie-breaks, empty-collection behavior, or cost/latency.

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

Conciseness5/5

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

Two tight sentences: the capability first, the scope constraint second. No filler, no restatement of the title, and every word earns its place.

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?

With an output schema and full annotation coverage, the description need not explain return values, and it is complete enough to call the tool correctly. Minor gaps remain: what happens if the collection has no contacts and what the ranking does with ties or missing data.

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 description coverage is 100% and the enum values are already documented in the schema, so the description's criterion list largely restates it. The only added nuance is the parenthetical gloss that 'decision-maker' means procurement/buyer plus seniority, which is a modest, not decisive, contribution.

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?

States a specific verb (ranks) and a specific resource (contacts saved on a collection), and enumerates the four ranking criteria. It narrows scope against contact-discovery tools via 'Does not discover new contacts', though it does not name the closest sibling (exim__employees__filter) it should be preferred over.

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

Usage Guidelines3/5

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

The exclusion ('Does not discover new contacts') gives one clear when-not boundary, which is useful. But there is no positive when-to-use guidance (e.g. 'use after items__add to order a saved list') and no named alternative such as exim__employees__filter or exim__prospects__find for discovery, so routing is only implied.

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