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

Annotations already declare readOnlyHint, idempotentHint, non-destructive and closed-world, so safety is fully covered structurally. The description adds that the payload is a set of reflective questions, but says nothing about how many, whether they are fixed or vary per call, or what the response shape looks like — which is the only behavior an agent still needs to know.

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?

Effectively two short sentences with the purpose front-loaded and no filler. The Spanish line is arguably redundant given the lang parameter, but it is brief and consistent with the tool's bilingual nature.

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-required-parameter, read-only tool with a fully documented enum and no output schema, the description is close to sufficient. Still missing is whether the question set is static across invocations, which an agent would want before calling it repeatedly for iterative self-review.

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 coverage is 100% and the single 'lang' enum is fully documented with default 'es', so the description owes little. The bilingual ES line hints at the multilingual output, but no language behavior (e.g., fallback) is added beyond the schema; baseline 3 applies.

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 names a specific resource (examen of conscience questions) and states their intended use: an agent reviewing its own work honestly. That is materially clearer than a tautology and separates it from doctrinal siblings like catechism or commandments, though it never explicitly contrasts with them.

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 phrase 'for an agent to review its own work honestly' implies the moment of use (self-check after producing output) but gives no explicit trigger, no exclusions, and no reference to any sibling tool as an alternative. Usage is inferable rather than stated.

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