The ten sephirot

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

Annotations already establish that this is a safe, read-only, idempotent operation. The description adds useful behavioral context: the result is static reference data, not computed output, and the response itself says so. It does not cover caching or rate-limit behavior, but those are less critical here.

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?

The core description is front-loaded into two efficient sentences, followed by useful metadata tags for group, endpoint, and cost. It is appropriately sized for a simple reference tool, with no redundant explanation.

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 zero-parameter reference tool with an output schema, the description supplies enough context: the fields included, grouping by pillar, and the fact that no computation occurs. The output schema carries the return-value detail, so nothing essential 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?

The tool takes zero parameters, so there is no parameter semantics to explain. The description appropriately focuses on what the static table contains rather than inventing input details.

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 identifies a specific resource: a static Tree of Life reference table containing Hebrew names, meanings, pillars, triads, and Golden Dawn planetary attributions. It is distinguishable from computational Kabbalah tools by stating 'Nothing here is computed,' though it does not name sibling tools such as gematria or shem names.

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?

Usage is implied by calling it a 'reference table' and noting that nothing is computed, which suggests lookup rather than calculation. However, there is no explicit guidance on when to choose this over related Kabbalah tools or what questions it is best suited to answer.

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