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

With annotations already declaring destructive=true and idempotent=true, the description adds useful non-obvious context: Startup-or-higher entitlement, read and write consent, stable idempotency key, exact-intent confirmation, and revision handling. It does not explain the concrete consequences of approval, such as locking or finality.

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?

Three tightly written sentences with no filler: purpose first, then requirements, then state/revision guidance. Every sentence earns its place and the action is front-loaded.

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 destructive approval tool with annotations and an output schema, the description covers the important prerequisites, idempotency, confirmation, and revision behavior. It could be more complete by stating what approval actually changes, but return values are already delegated to the output schema.

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%, so the description must carry parameter meaning. It explains content_hash, evidence_fingerprint, idempotency_key, confirmation_token, and revision/expected_version semantics, but leaves project_id, close_id, and report_id unexplained.

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 states a specific verb and resource: approving an exact monthly report by content hash and evidence fingerprint. It is clearly distinguishable from siblings such as save_report and publish_report because it targets exact approval artifacts rather than saving or publishing.

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?

It gives clear usage context: approve after reviewing the report text and source exceptions, and read current state before changing an existing record. Prerequisites are stated, but no alternatives or when-not-to-use guidance is provided.

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