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

Annotations already establish that this is a read-only, idempotent, non-destructive, closed-world operation. The description adds useful content-level context about ceilings and recently auto-executed actions, but it does not add much behavioral detail beyond what the annotations already provide.

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 description is a single dense but front-loaded sentence that immediately identifies the tool as an analysis view. The parenthetical list of action kinds and ceiling types is information-rich, though the sentence is somewhat heavy.

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 parameters, rich annotations, and an output schema, the description provides enough context about what the tool returns: rights per action kind, ceiling values, and recent autonomous actions. It could be slightly more explicit about the relationship to action_rights_set, but it is otherwise complete for invocation.

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?

The tool has zero parameters, so the baseline for parameter semantics is 4. The description does not need to document parameter behavior, and the empty schema is consistent with a no-argument listing/analysis tool.

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 clearly states that this tool surfaces execution rights per action kind, including auto/approve/never states, ceilings, and recently auto-run actions. It is specific about the resource and scope, but it does not explicitly distinguish itself from the sibling action_rights_set beyond implied read-only analysis.

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 labels the tool as an analysis view and describes what it contains, but it gives no explicit when-to-use guidance, prerequisites, or comparison to alternatives such as action_rights_set or list_pending_actions. The intended use is implied rather than stated.

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