Api timeline entries retrieve

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

Annotations already declare readOnly, idempotent, non-destructive and open-world, so the safety profile is covered. The description's one real contribution is disclosing that unauthorized related fields are masked in the response, which is behavioral context not present in annotations. It stops short of saying which fields are masked or how missing/forbidden IDs are surfaced.

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?

A single short sentence with no filler, which is good, but the terseness is under-specification rather than economy — the one sentence omits the resource, the identifier, and the return shape.

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?

For a single-object lookup with one undocumented parameter and no output schema, the description should state what entity is returned and roughly what the object contains. Neither is present, leaving the agent unable to confirm this is the timeline entry read it wants.

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?

There is one required parameter, id, with 0% schema description coverage, so the description carries the full burden. It says nothing about what the id identifies (primary key? ref_id? UUID format?) or the failure behavior for an unknown id.

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?

"Return a single object" is a generic verb+generic-resource that never names the resource (a timeline entry) or that it is selected by ID. It also fails to distinguish this from the sibling ciso_assistant_api_timeline_entries_object_retrieve, which appears to do the same thing.

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?

There is no when-to-use, no when-not-to-use, and no mention of the very similar object_retrieve sibling. An agent choosing between this and the sibling has nothing to go on from the description.

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