B3.2/5.0
Behavior3/5

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 covered. The description adds genuinely new behavioral information the annotations lack: the POST endpoint and a cost of 20 credits (Tier 2), which matters for an agent budgeting calls. It says nothing about output shape or how many planets are returned.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness4/5

Is the description appropriately sized, front-loaded, and free of redundancy?

One dense, well front-loaded sentence states the operation, followed by three short structured metadata lines (group, endpoint, cost). Nothing is padded, though the bracketed metadata is boilerplate rather than explanatory.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness3/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

An output schema exists and the input schema is fully documented, so the description needn't explain return values or parameter formats. Still, for an essential-dignities tool the modern/traditional ruler-set choice is central to interpreting results, and a one-clause mention of it would have closed the remaining gap.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 100%, so the heavy lifting is already done by the schema. The description adds only 'for each planet' and never mentions the mode switch (modern vs traditional) that changes which planets receive dignities, nor custom termsData/decansData, so it does not compensate beyond the schema baseline.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose4/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description gives a specific verb ('Calculate') and resource ('the five Ptolemaic essential dignities') and even enumerates the five: rulership, exaltation, triplicity, term, face, plus debilities. An agent knows exactly what comes back. It does not, however, distinguish this from sibling dignity tools such as almuten, receptions, or disposition_chains.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines2/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

There is no sentence telling the agent when to pick this over astroway_dignities_almuten, astroway_dignities_receptions, or the disposition-chain tools, and no prerequisites or exclusions. The '[Group: Dignities & Receptions]' tag and the tool name are the only routing signal.

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