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

Annotations already establish the safety profile (readOnlyHint=false, destructiveHint=false, idempotentHint=true), so the '🟡 WRITE · updates data' prefix adds little. The explicit PUT method offers mild extra context implying full-resource update semantics consistent with the required amount/date/statement_balance fields, but no further behavior such as validation rules or effects on related records is disclosed. No contradiction with annotations.

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 short and front-loaded with a useful WRITE/PUT marker, but it restates the same operation three times ('updates data', 'Update bank statement transaction', 'updating an existing bank statement transaction'). The final two sentences are redundant and could be merged into one.

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 tool with a nested body object, three required parameters, and no output schema, this description is too thin. It provides no domain context about statement transactions, no update semantics beyond the bare verb, and no validation constraints, and with 50% schema coverage the unexplained parameters leave an agent under-informed.

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 only 50%, and several parameters (bank_account_id, id, date, reference, description, bank_reference) have no descriptions. The tool description adds nothing about parameter meaning, relationships, or required body fields, so it fails to compensate for the coverage gap; only the idempotency_key schema text is genuinely informative.

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 names a specific verb and resource ('Update bank statement transaction', 'updating an existing bank statement transaction') and the PUT path identifies the exact target. The action distinguishes it from the create/retrieve/list/destroy siblings on the same resource, though it does not explicitly contrast with partial_update.

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 given on when to use this tool versus the sibling partial_update, create, retrieve, or destroy variants. There is no mention of prerequisites, typical use cases, or exclusions, so an agent gets no help choosing this over alternatives.

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