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

Annotations already declare readOnly/idempotent/non-destructive, so safety is covered. The description adds substantial behavioral context beyond that: pagination ('Pass next_cursor verbatim as cursor... null on the last page'), empty-list meaning, and the action_role lifecycle including the side effect that undoing a decision rebuilds its action from the next claim.

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?

It is front-loaded with the core purpose, but the body is a single dense run-on covering action_role, site conflicts, not-on-site choices, pagination and empty state. Much of the field semantics is justified because there is no output schema, yet the paragraph could be broken up for far easier parsing.

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 and 0% param coverage, the description carries the burden and largely meets it by explaining the returned fields, the action_role state machine, conflict URL semantics, choice values, and pagination. Gaps remain: no limit guidance and no differentiation from the other accuracy list/get tools.

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?

With 0% schema description coverage, the description must compensate. It does well for 'cursor' ('Pass next_cursor verbatim as cursor for the next page; it is null on the last page') but says nothing about 'limit', whose default 25 and max 100 live only in the machine-readable schema constraints.

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?

It states a specific verb and resource ('List the Accuracy Reviewed list: the decisions the team made on claims, newest first') and even enumerates the fields returned, so the tool's function is unmistakable. However, it never distinguishes itself from near-name siblings like devtune_list_accuracy_claims or devtune_get_accuracy, so it stops short of full sibling differentiation.

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 explains what the list contains but gives no when-to-use context and never names an alternative such as devtune_list_accuracy_claims or devtune_get_accuracy_claim. Usage is at best implied by the wording, leaving the agent to guess which accuracy tool to call.

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