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

Annotations already declare readOnlyHint=true, idempotentHint=true, openWorldHint=true and destructiveHint=false, so safety behavior is covered. The description adds useful content-level context about what is returned (manifest, exact revisions, provenance, published customer guide links). It omits any mention of tenant scoping, auth requirements, or whether the published guide links are public URLs.

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 dense, front-loaded sentence with no hedging or filler. It is, however, verbatim identical to the title, so the description field contributes no additional structure or emphasis of its own.

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 output schema, the description does enumerate the kinds of content returned, which is the main thing an agent needs. But for a read tool over a company-scoped manifest it leaves open result shape, ordering, size, and whether revisions are per-document or aggregated — details that must live somewhere and currently live nowhere.

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% for the single required 'company' UUID parameter, so the description carries the burden and does not meet it. 'Company document revisions' gestures at company scoping but never states that a company UUID must be supplied or what it selects. An agent must open the schema to learn this is a mandatory identifier.

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 sentence names a specific verb ('Read') and a specific resource set: the effective knowledge manifest, exact shared/company document revisions used by agents, plus provenance and published guide links. That is far more informative than the bare name 'summer_knowledge_effective'. It does not, however, distinguish this from the many other knowledge siblings (get, list, changes, history, adoptions), so an agent still has to infer 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?

There is no guidance on when to call this instead of summer_knowledge_get, summer_knowledge_list or summer_knowledge_changes, and no prerequisites or exclusions are stated. The word 'effective' implies a resolved/live view but the description never explains that contrast.

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