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

Annotations already declare readOnlyHint=true, idempotentHint=true, destructiveHint=false, and openWorldHint=false, so the safety profile is fully covered. The description adds a genuine epistemic trait beyond annotations — output is evidence-linked and explicitly avoids deterministic outcome claims — which sets expectations for how results should be framed. It stops short of describing depth, determinism of scope, or any limitations.

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 with no filler, which is appropriately sized, but the phrasing is awkward ('Evidence-linked analyze career structure') and reads as a name-plus-disclaimer rather than a front-loaded statement of purpose. Brevity here reflects under-specification rather than disciplined concision.

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 tool with 10 parameters, two input modes (place or lat/long/timezone), and a topics enum, the description omits input guidance, topic selection, and how results relate to the sibling analyzers. An output schema exists, so return format needn't be explained, but nearly everything else an agent needs for correct invocation is missing.

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 detail: it never mentions date, time, the place-vs-coordinates anyOf requirement, the topics enum, or asOfIso. With 10 parameters and two mutually exclusive input modes, the description leaves the agent to reconstruct input requirements entirely from the schema. It does not compensate for the coverage gap.

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 sentence essentially restates the tool name ('analyze career structure') with two qualifiers, so an agent learns nothing about what the analysis actually produces or what domain inputs drive it. 'Evidence-linked' and 'without deterministic outcome claims' describe epistemic posture, not the operation. No differentiation from siblings like analyze_house or analyze_chart_topic.

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 exclusions, and no named alternative among the many overlapping siblings (analyze_chart_topic, analyze_house, analyze_yogas, detect_life_themes). The only implicit hint is that the tool concerns careers. Nothing tells the agent when this tool is the right choice over a broader chart analysis.

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