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

With no annotations, the description carries the full behavioral burden. It helpfully discloses the returned fields and hints at a permission/role gate, but omits pagination behavior beyond the limit param, ordering, and what happens when no acts are readable.

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 sentences, front-loaded with the core action and the resource. The parenthetical field list is informative rather than wasteful, though 'what this installation's agents have already read off the official sites' is slightly verbose.

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 usefully spells out the returned fields, which an agent cannot get elsewhere. It is reasonably complete for a simple list tool, lacking only ordering/pagination behavior and clearer access semantics.

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 limit and filter are already fully documented in the schema. The description adds no syntax, format, or semantic detail beyond what structured fields provide, making the baseline 3 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 verb+resource ('List the acts in the legal library') and even enumerates the fields returned (url, title, fetched_at, checked_at, length). It does not, however, explicitly distinguish itself from the sibling search_legal_library, so an agent must infer the difference from the verb alone.

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 trailing phrase 'Open where the company lets an agent role read laws' gestures at an access condition but is too cryptic to act on. There is no explicit when-to-use guidance and no mention of the obvious alternative search_legal_library for filtered lookups.

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