plaid_transactions

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

Annotations already declare readOnlyHint=true, idempotentHint=true, destructiveHint=false and openWorldHint=true, so the description carries a lower burden. It adds nothing beyond them: no rate-limit behavior, no pagination semantics despite count/offset existing, and no note that credentials are required to authenticate against a live Plaid environment.

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 zero filler. It is efficient, but its brevity is achieved by omission rather than by tight writing, so it sits just below the top mark.

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 9-parameter authenticated financial-data read with no output schema, the description should cover credential requirements, paging, and account filtering. Instead it says only that transactions fall in a date range, leaving most of what an agent needs to call it correctly undisclosed.

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 33% across 9 parameters. The description's 'date range' merely echoes the already-documented start_date/end_date, and it says nothing about count (max 500, default 100), offset paging, account_ids filtering, or the sandbox/development/production environment enum — all of which the schema leaves bare or thin.

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 and resource (get transactions) plus a scope qualifier (Plaid-linked item, date range). It is clearly the transactions-fetching member of the plaid_accounts / plaid_balances / plaid_identity family, though it never names those siblings to sharpen the distinction.

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 gives no when-to-use guidance, no prerequisites (a client_id/secret/access_token triple is required), and no indication of what to call if the agent wants balances, identity, or accounts instead. Usage is only inferrable from the tool name.

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