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

Annotations already declare readOnlyHint, idempotentHint and destructiveHint=false, so 'No changes are made' is largely redundant. The description does add genuinely new behavioral context with the 'newest first' ordering, but it says nothing about pagination behavior despite the offset parameter.

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?

Two short sentences, front-loaded with the resource and ordering. The closing 'No changes are made' earns little because the annotations already assert it, so the description is efficient but slightly padded.

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?

An output schema exists, so return values need no explanation, and the read-only nature is covered. However, for a tool with an offset parameter the absence of any pagination or paging guidance leaves a real gap for an agent that must fetch long histories.

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 the description names neither parameter. curriculumEntryId's role is inferable from the tool name, but the offset parameter and its pagination semantics are entirely undocumented in both the schema and the description, so the description fails to compensate for the coverage gap.

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 gives a specific verb ('Read') and resource ('previous and new content for a saved curriculum entry') plus ordering ('newest first'), which is enough to separate it from get_curriculum_context and curriculum_audit. It stops short of naming the siblings it should be chosen over, so it is clear but not fully differentiated.

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?

Usage is only implied: an agent can infer this is for inspecting the change history of one entry, but the description never states when to prefer it over get_curriculum_context, curriculum_audit, or search_curriculum. No prerequisites or exclusions are given.

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