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

Since no annotations are provided, the description carries the full burden. It discloses key side effects: it groups charges, sends one message per client, creates confirmation tokens, and sets a grace period for auto-confirmation. This goes beyond a simple 'send' and informs the agent of consequential actions. It does not mention failure modes or whether the operation is reversible, but the core behavior is well covered.

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 three sentences, front-loaded with the primary action, and every sentence adds meaningful detail (grouping, channel, token creation, confirm requirement). There is no fluff or irrelevant information.

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?

The tool has 5 parameters, no output schema, and no annotations, so the description must cover operation, return value, and parameter nuances. It covers the action and notable side effects, but omits what the tool returns (e.g., status, counts), how clientId affects behavior, and error conditions. It is adequate for basic understanding but not fully complete for safe 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?

The schema has 0% description coverage, so the description must compensate for all parameters. It only clarifies that 'confirm' must be true and implicitly references the 'channel' option ('via WhatsApp or email'). It leaves 'orgSlug', 'apiKey', and 'clientId' unexplained, including how clientId might filter which clients receive the digest. This is a significant gap for a 5-parameter tool.

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 opens with 'Send pending confirmation digest to clients,' which uses a specific verb and resource. It clearly distinguishes from sibling tools like finance_list_confirmations (listing vs. sending) and describes the grouping and channel mechanism, making the tool's purpose unmistakable.

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 description provides clear context for when to use the tool: it sends a digest of pending confirmations, grouping by client. It also states 'Requires confirm: true,' which is a strong prerequisite. However, it does not explicitly mention alternatives or when not to use it (e.g., for a single client or non-confirmation communications).

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