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

The annotations already declare readOnlyHint=true, idempotentHint=true, destructiveHint=false, and openWorldHint=false, so the safety profile is fully covered by structured data. The only added claim, "without deterministic outcome claims," hints at an epistemic/ethical constraint on the output but is too vague to be actionable; nothing is said about computation scope, required inputs, or how results are sourced.

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?

It is short, but brevity here reflects under-specification rather than conciseness: the single sentence is grammatically garbled ("Evidence-linked analyze career structure") and no sentence earns its place by conveying usable information. There is no front-loaded statement of what the tool returns.

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 tool with only 30% schema coverage, a required name/date/time triple, and an either/or location requirement, one vague sentence is wholly inadequate. Although an output schema exists (so return values need not be described), the description omits everything an agent needs to invoke 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 only 30% and the description adds zero parameter information, so the documentation burden falls entirely on the schema, which leaves latitude/longitude, asOfIso, timezoneOffset semantics and the anyOf place-vs-coordinates rule largely implicit. The description does nothing to compensate for this coverage gap across the 10 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?

"Evidence-linked analyze career structure without deterministic outcome claims" essentially restates the tool name and title rather than describing what the tool actually produces. It never says this is a Jyotish/astrological career reading, what inputs drive it, or what the analysis contains, so it does not distinguish it from siblings like analyze_finance_structure or analyze_education_structure beyond the word "career".

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 mention of prerequisites (birth name/date/time required), no exclusions, and no pointer to an alternative sibling tool. The single sentence offers no routing information an agent could act on when choosing among the many analyze_* tools.

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