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

Annotations already declare readOnly/idempotent/non-destructive, so the safety profile is covered. The description adds real behavioral context beyond that: the evidence is 'frozen' (snapshot/immutability semantics) and current owner direction overrides saved suggestions (a result-interpretation precedence rule). It stops short of describing auth or pagination.

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 tight sentences with the core read purpose and contents front-loaded, and no filler. The second sentence is terse but earns its place by stating a precedence rule.

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-value documentation is unnecessary, and annotations carry the safety profile for this read tool. The main shortfall is the absence of any parameter explanation, but otherwise the definition is sufficient to call the tool correctly.

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 never mentions jobId or workspaceId, so it does not compensate for the undocumented parameters. The agent must infer meaning purely from self-descriptive parameter names, which is a clear gap under the low-coverage rule.

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 resource (workspace learning job), plus the concrete contents returned: frozen evidence, creative lineage, progress, and saved lessons. It is distinguishable from learning_start/learning_control by the read framing, but it does not explicitly name or contrast those siblings.

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 guidance, no prerequisites, and no mention of the sibling tools (learning_start, learning_control, learning_quote) that an agent must choose between. The only supplementary sentence addresses precedence of results, not invocation context.

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