get_weak_areas

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

With no annotations, the description carries the full behavioral burden. It discloses that the tool derives a 'weakness score' from attempt history, which is real behavioral context beyond the schema. It does not state that the operation is read-only, whether scoring is deterministic or recency-weighted, or what happens with an empty attempt history.

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?

A single front-loaded sentence with no filler; the analytical intent arrives immediately. Slightly loose phrasing ('assign a weakness score to it') costs a little precision but nothing is wasted.

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?

For a parameterless read with an output schema, the description supplies the essential framing: inputs come from attempt history and the output is per-topic weakness scores. Missing is any hint about scoring scale or how many topics are surfaced, but the return structure is covered by the output schema.

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 tool takes zero parameters, so there is nothing for the description to clarify; the baseline of 4 applies. No parameter-level gaps exist.

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 and derived output: 'Analyze the user's attempt history' and 'identify DSA topics where the user appears to be struggling and assign a weakness score.' This is a concrete analytical product rather than a restatement of the name. It does not, however, explicitly contrast itself with siblings like get_attempt_history or get_topic_history that also operate on attempt 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?

Usage is implied by the framing ('analyze the user's attempt history') but there is no explicit when-to-use, no prerequisites (e.g. requires logged attempts), and no named alternative such as get_attempt_history for raw data versus this diagnostic view. The agent can infer the intent but gets no routing guidance.

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