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

Annotations already declare readOnlyHint, idempotentHint, openWorldHint and destructiveHint=false, so the safety profile is fully covered. The description contributes only the notion that this returns a log of edits/uploads/publications, with no mention of ordering, pagination, volume or whether the history is scoped to a time window; with annotations carrying the burden, a 3 is appropriate.

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 short, front-loaded sentence with zero padding, which is appropriate for a simple read tool. It is essentially a restatement of the title, so brevity here edges toward under-specification rather than deliberate economy.

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?

No output schema exists, so the description should say more about what comes back (entry types, ordering, result size/pagination). It names the three history categories, which is a useful start, but an agent still cannot tell how many records to expect or whether a time filter is possible.

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 single parameter (company, UUID, 'Summer company ID') is 100% documented in the schema, so the schema does the work. The description adds nothing about the parameter (e.g. whether it accepts a slug or requires the canonical company UUID), so baseline 3 applies.

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 (the company's guide edits, upload and publication history), which is more precise than the bare tool name. It does not distinguish itself from adjacent read tools such as summer_guides_get, summer_guides_articles_get, summer_knowledge_history or summer_saved_replies_history, all of which could plausibly return history-like data.

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?

No guidance on when to use this versus the many sibling read tools, no prerequisites, and no exclusions. The agent must infer usage entirely from the tool name and its own knowledge of the product.

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