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

Goes well beyond the annotations: it explicitly bounds the side effects ('No messages, filings or money movement occur'), states required consent levels and confirmation semantics, mandates a stable idempotency key, and adds optimistic-concurrency guidance ('use its current revision when changing an existing record'). Annotations only supply the destructive/idempotent flags; the description supplies the operational contract, and nothing contradicts them.

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?

Four sentences, no filler, purpose front-loaded ahead of preconditions. Dense but every sentence carries information; slight compression of the concurrency advice costs a little readability.

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, idempotent mutation with an output schema already present, the definition covers preconditions and side-effect boundaries well. It is not fully complete: it never says what 'due work' is selected or what happens on an idempotent replay, though these are minor against the rest.

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 description coverage is 0%, so the description must carry the parameter burden. It adds real meaning for idempotency_key ('stable') and the confirmation payload ('exact-intent confirmation') and ties the call to a project, but it never explains project_id's type/role or the nested confirmed=true const requirement, leaving gaps.

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 verb ('Process') and resource ('bounded due monthly reporting and obligation work') scoped to 'this project'. Clear enough to distinguish from non-founder_ops siblings, but it does not name or differentiate from adjacent siblings like founder_ops.prepare_monthly_close or founder_ops.complete_occurrence.

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?

Prerequisites are stated (Startup tier, read+write consent, idempotency key, exact-intent confirmation), which implies the correct calling context. However, there is no explicit when-to-use versus alternatives guidance, and no sibling is named as the wrong tool to pick here.

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