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

The annotations already establish readOnly, idempotent, non-destructive, and open-world, so the safety profile is covered. The description adds one genuinely useful detail beyond that: the returned edit reasons are 'authenticated', meaning attributions are trustable. It says nothing about ordering, pagination, or completeness of the revision set.

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?

One tight, front-loaded sentence with no filler. It is efficient, though it is nearly a verbatim restatement of the title, so nothing is added to orient the reader beyond that single clause.

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?

There is no output schema, no annotation-level detail about return shape, and no parameter documentation, so the description is the only place to explain what the revision history looks like (ordering, volume, whether reasons can be null). For a three-required-parameter history endpoint with zero schema coverage, the single sentence leaves real gaps.

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 0% and there are three required parameters (job UUID, company UUID, environment enum), none of which the description explains. The agent gets no hint about what the UUIDs refer to, whether environment scoping changes results, or any format guidance, so the schema/documentation gap is not compensated.

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 (Read) and a specific resource (saved scheduled-job definition revisions, plus edit reasons). This is distinguishable from siblings like summer_scheduled_jobs_list or summer_scheduled_jobs_runs, though the description never names those siblings explicitly to reinforce the boundary.

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 word 'history' implies the audit/inspection use case, and 'revisions' implies looking at prior versions rather than current state. But there is no explicit when-to-use guidance versus summer_scheduled_jobs_list, summer_scheduled_jobs_runs, or summer_scheduled_jobs_save, and no stated prerequisites.

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