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

There are no annotations, so the description must carry the full burden of behavioral disclosure. It only states a mutation ('Record') and the outcome type, but does not describe side effects (e.g., updating scheduling, idempotency), required prior state (e.g., memory must exist), or any other behavioral traits. This is a significant transparency gap for a write operation.

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?

The description is a single, concise sentence that is front-loaded with the key action and subject. No wasted words; it efficiently conveys the core purpose. Structure is appropriate for the tool's simplicity.

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 annotations and no output schema, the description is the sole source of context. It is too sparse given the large sibling set and the nature of the operation (recording an outcome could have downstream effects). The description does not explain the workflow, prerequisites, or relationship to other tools, making it incomplete for an agent to use correctly in context.

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%, so the description must compensate. The description hints that 'success' is a boolean for success/fail, adding some meaning beyond the schema's bare boolean type. However, it does not explain 'memory_id' or what happens if 'success' is omitted. The description provides minimal semantic value for one parameter and none for the other.

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 uses a specific verb ('Record') and identifies the resource ('spaced-repetition outcome') and the data shape ('success/fail'). This is clear about what the tool does, though it does not explicitly differentiate itself from similar siblings like 'record_outcome' or 'review_batch'.

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 is provided about when to use this tool vs alternatives. The description only states the action ('Record a spaced-repetition outcome') without mentioning context, prerequisites, or exclusions. There is no 'use this when...' or 'instead of...' guidance, leaving the agent without clear direction on selecting this tool among many siblings.

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