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

Annotations already declare readOnly, non-destructive and closed-world, so safety is covered. The description adds real value by disclosing the log's payload (decision + rationale) and a prompt-injection caution about third-party comment text; it does not address ordering, retention window or volume of entries.

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 compact sentences with the core purpose front-loaded, followed by the optional filter and the safety note. No filler, though the safety note is slightly disconnected from the reading flow.

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?

With no output schema, the description carries the return-value burden and does so by naming the fields the log exposes. Remaining gaps — recency ordering, pagination and entry count — are minor for a small read-only log tool.

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 only 33%, with just brand_id documented in the schema. The description clarifies that rule_id is optional and accepts a single rule, which is useful, but adds nothing about limit or the brand_id scoping rule beyond what the schema already says.

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 resource (the comment bot's recent log) and enumerates its content — which comment was seen, the decision (replied/suggested/skipped) and the reason. This clearly separates it from config-side siblings like update_comment_bot or list_comment_bots, though no sibling is named explicitly.

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?

'Opcional una sola regla' implies the tool can be scoped to one rule, hinting at usage, but never states when to pick this over the nearby get_activity_log or when-not to use it. The agent must infer the distinction from the name.

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