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 genuinely non-derivable context: that user-written content is returned as data and never as instructions (prompt-injection stance), and that an OAuth account is required, with the tool reporting its absence.

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?

The opening clause is well front-loaded, but the rest is a single sprawling sentence with nested parenthetical enumerations that are hard to parse. Nearly every clause is informative, yet the density and structure could be trimmed into separate sentences for readability.

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 only two parameters, a full enum, annotations, and an output schema (so return values need not be described), the description covers the remaining gaps: auth requirement and the content-as-data safety note. It is essentially complete, though it could state when a sibling search tool is preferable.

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% and the kind enum is fully documented in the schema, so the schema carries the parameter burden. The description restates each kind with slightly more detail (e.g., 'e_…' with verification state), but adds little beyond what the enum descriptions already say.

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 ('Reads one object') plus the resource (the user's JusticeLibre account) and enumerates the four kinds of objects it can return. An agent can distinguish it from create_account_item, update_account_item, delete_account_item, and the search_* siblings without opening any schema.

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 maps each kind to its use case (account, case_file, item, ticket) and tells the agent that id is omitted for kind=account, which implies when to call it. However, it never names an alternative for retrieving data (e.g., search) or states when NOT to use this tool, so usage is implied rather than explicit.

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