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

Annotations already declare readOnlyHint=true and destructiveHint=false, so safety is covered. The description adds behavioral richness beyond that: it surfaces multiple candidate Hebrew spellings, names the chosen one, and enumerates the response contents including readings, per-letter breakdown, sephirah, and curated shared-value words. No contradiction with annotations.

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?

Two dense, front-loaded sentences: the first defines the core behavior and differentiator, the second inventories the response and target use cases. Every clause earns its place and there is no filler or circular wording.

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 6 parameters, 3 enums, and no output schema, the description compensates by describing the response shape and intended contexts. It relies appropriately on the schema for parameter semantics; a minor gap is that it does not explicitly state that one of name or nameHebrew must be provided, though the schema makes that discoverable.

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%, so the baseline is 3. The description alludes to spelling selection and transliteration nuance, which connects to name/nameHebrew/transliteration, but it does not add parameter-level details beyond what the schema already provides.

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 clearly states the action ('Score a name'), the method ('rabbinic gematria ciphers', 'Tree of Life'), and the distinctive output ('every candidate Hebrew spelling shown and the chosen one named'). This separates it from sibling gematria or name tools by framing it as a full name-reading profile rather than a simple cipher lookup.

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 description gives concrete intended use cases: 'name meaning pages, Kabbalah numerology features and any product that wants a name reading it can defend line by line.' This tells an agent when to reach for this tool, though it does not explicitly name sibling alternatives or states when not to use it.

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