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

Annotations already declare readOnlyHint=true and openWorldHint=false, so safety is covered. The description adds real context beyond that: it states the data is 'Facts as the contract states them; the contract text governs' (a fidelity caveat) and 'Free (no credit)' (cost behavior not present in annotations).

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?

Purpose is front-loaded in the first clause, but the middle sentence is a long, comma-heavy enumeration ('the date inputs, the term, notice and renewal inputs and the agreed option of each term, renewal, termination, notice or duration clause') that is hard to parse and partly redundant.

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?

With no output schema, the description does the work of explaining what is returned: the obligations ledger and the date/term/notice/renewal inputs per clause. It omits any note on result shape, ordering, or volume, but for a read-only per-deal listing it is largely complete.

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 50%; dealId is well documented in the schema ('dealId from generate_contract') and lang is a self-explanatory en/es enum, so structured fields carry most of the weight. The description adds no parameter meaning, so the 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?

States a specific resource and content: 'What a contract commits its parties to and the dates it states', then enumerates the obligations ledger plus term/notice/renewal inputs. Clear verb-implied retrieve/list of a concrete resource, but it never distinguishes itself from the nearby get_deadlines sibling, so sibling differentiation is missing.

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?

There is no explicit when-to-use or when-not-to-use guidance and no alternative tool is named, even though get_deadlines and get_deal overlap. The only context clues are a scope aside ('for the DPA today') and 'Free (no credit)', which conveys cost rather than usage routing.

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