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

Annotations already declare readOnlyHint, idempotentHint, non-destructive, and closed-world, so safety behavior is covered. The phrase 'Evidence-linked ... without deterministic outcome claims' adds a genuine epistemic trait (the output will be sourced and non-fatalistic), which is useful beyond annotations, though it is too vague to describe output format or limits.

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 short sentence, but it is under-specified rather than concise — it mostly echoes the name/title and omits the information an agent needs. Brevity here reflects missing content, not efficiency.

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 10-parameter, anyOf-constrained tool with an output schema and many domain siblings, the one-sentence description is grossly incomplete. Return values are covered by the output schema and safety by annotations, but usage, parameter meaning, and analytical scope are all absent.

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?

With 10 parameters and only 30% schema description coverage, the description must compensate and adds nothing: no mention of date/time requirements, the place-vs-coordinates anyOf branch, topics, asOfIso, or name. An agent gets no semantic help for the undocumented parameters.

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 is essentially the title restated: 'Evidence-linked analyze education structure without deterministic outcome claims.' It names no specific analytical content (houses, planets, dashas, etc.) that would let an agent distinguish this education analysis from the many sibling 'analyze_*_structure' tools. The only added content is an epistemic disclaimer, not a purpose statement.

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 use this tool versus siblings like analyze_career_structure, analyze_marriage_structure, or analyze_chart_topic, nor any prerequisites or exclusions. The description gives no context for selection.

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