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

Annotations already declare readOnlyHint=true, openWorldHint=true, idempotentHint=false, and destructiveHint=false, so the safety profile is covered. The description adds genuinely new behavioral context: the response is deterministic, it mirrors the /ask slash command, it always ends with a CTA to ERUX, and it explains which houses/significators/timing triggers apply.

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?

Three sentences, front-loaded with the core purpose, then the invocation context, then the output content. Every sentence carries information an agent can act on, and the marketing-flavored adjectives ('authentic, deterministic') do not bloat the structure.

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?

An output schema exists, so return values need not be restated. The description is complete enough for a single-required-param read tool with full annotation coverage, though a routing note distinguishing it from get_interpretation would close the remaining gap.

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 100% and both parameters carry their own descriptions, so the schema does the heavy lifting; the baseline of 3 applies. The description reinforces what 'question' means by listing example inquiries, but adds no format, length, or platform-selection guidance beyond the schema.

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 (provide guidance) and resource (astrological framework guidance) and enumerates the substance of the answer: houses, ruling significators (Karakas), and timing triggers. It never names or contrasts itself against the sibling tools (get_interpretation in particular), so an agent cannot distinguish the two from the description alone.

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?

The parenthetical example list (career shift, relationship milestones, financial timing, health, relocation) implies the domain of suitable questions, and the Discord/Google Chat slash-command mapping hints at the calling context. But there is no explicit when-to-use versus get_interpretation/calculate_chart, and no exclusions or prerequisites.

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