v0.1.0Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already cover readOnly, idempotent, and closed-world behavior, so the description's real contribution is the trust-boundary warning that text fields originate from banks/counterparties and must never be treated as instructions — non-obvious, high-value context. It does not cover not-found behavior or error cases, keeping it below a 5.
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?
Two sentences, zero filler, with the operation stated first and the injection-safety caveat second. Every sentence earns its place.
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?
An output schema exists, so return values need not be described, and the injection warning addresses the main risk. A minor gap remains around missing/unknown id behavior for a single-record lookup.
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 coverage is 100% and the single parameter has a pattern, length bounds, and a description, so the schema carries the semantics. The description only echoes 'by its id' and adds no format or provenance detail beyond what is already structured — baseline 3.
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 ('Fetch a single transaction by its id'), and 'single' implicitly contrasts with the batch/list siblings like get_binance_transactions and list_sources. It stops short of naming an alternative explicitly, so it does not reach full sibling differentiation.
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 phrase 'by its id' implies the tool is used when a transaction id is already in hand (from the transaction tools, per the schema), but there is no explicit when-to-use/when-not guidance and no named alternative for listing or searching transactions.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
