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

Annotations already declare readOnlyHint, idempotentHint, and destructiveHint=false, so the safety profile is covered. The description adds a genuine behavioral fact beyond them: the tool requires admission via atlas.enroll followed by atlas.bind_actor, an auth prerequisite not visible in the annotations or schema. It stops short of describing what the returned records contain.

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?

Two compact fragments with the prerequisite correctly front-loaded, so nothing is wasted. The trade-off is under-specification rather than excess: the body sentence is a noun phrase that conveys very little, which is terseness, not efficiency.

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 rich annotations and 100% schema coverage, the remaining burden is describing the return value, and there is no output schema. "Verification records for a matter" is too vague to tell an agent what it will receive (receipts? signatures? status?), so the definition is adequate but leaves a real gap for a query tool.

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 description coverage is 100%, so both matter_id and actor_token are fully documented in the schema, including the "optional when bound to exactly one matter" nuance. The description contributes no additional parameter meaning, which is the expected baseline when the schema does the heavy lifting.

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?

The description names a resource ("verification records for a matter") but the phrasing is a bare noun fragment with no verb, and "resulting state" in the name/title is never explained. An agent cannot confidently distinguish this from siblings like atlas.get_matter, atlas.get_context, or atlas.get_authority without opening schemas.

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 bracketed prerequisite "[NEEDS ADMISSION: enroll, then atlas.bind_actor]" gives real, actionable routing to two sibling tools, which is more than most definitions offer. However, it never states when to call this tool versus other state/introspection tools such as atlas.get_context or atlas.get_matter, so selection guidance is only implied.

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