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

No annotations are provided, so the description carries the full behavioral burden. It conveys the resulting state ("not a sale") but says nothing about reversibility, required permissions, whether the credit is removed from reporting/reconciliation, or what happens if the credit was already assigned.

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?

A single front-loaded sentence with no filler. It is efficient, though the extreme brevity for a mutation tool edges toward under-specification rather than disciplined conciseness.

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 state-changing tool with no annotations, no output schema, and an undocumented required parameter, the description is too thin. An agent cannot confirm prerequisites, side effects, or the response shape before invoking it.

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?

There is one required parameter (credit_id) at 0% schema description coverage, and the description never mentions it. It does not state the expected ID format, where the ID comes from (e.g., list_bank_credits), or what happens with an unknown ID, so it adds no meaning beyond the bare schema.

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 pairs a specific verb ("dismiss") with a specific resource ("bank credit") and clarifies the semantic effect ("as not a sale"), which meaningfully separates it from the sibling assign_bank_credit. It stops short of naming the alternative tool or the state the credit ends up in, so it is clear but not fully differentiated.

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?

There is no statement of when this tool should be used versus assign_bank_credit, list_bank_credits, or any other sibling. An agent must infer the trigger condition (a credit that is not a sale) entirely from the one-line effect description.

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