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

With no annotations, the description carries full behavioral burden. It reveals that 'add=true' triggers a log action but leaves unclear what happens when add is false or omitted (e.g., listing/tracking behavior). No side effects, permissions, or return behavior are disclosed.

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 description is concise at two clauses and front-loads the primary purpose. However, it sacrifices clarity about the tool's full behavior to achieve brevity, so it's slightly under-specified for a 7-parameter tool.

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 7-parameter tool with no annotations or output schema, the description is minimal. It fails to explain return values, the effect of other parameters, or the default behavior when 'add' is not true, making it incomplete for reliable invocation.

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 0% and the description only explains the 'add' parameter. The other six parameters (notes, decision, reviewer, account_id, review_date, overdue_days) receive no semantic clarification, leaving significant ambiguity for agent usage.

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 'Track access recertification reviews' with a specific verb and resource. It distinguishes from siblings like 'access_gap_analysis' and 'mfa_compliance' by focusing on recertification, though it doesn't explicitly name alternatives.

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?

No guidance is provided on when to use this tool versus siblings; the only conditional is 'Set add=true to log a review,' which does not cover when to use the tool for tracking/list scenarios. Alternatives are not mentioned.

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