Payments Law — EU payments legislation

Read legislative source notes

get_source_notes

Read-onlyIdempotent

Use this to read the original legislative footnotes and source-note bodies for a held instrument, including preamble and annex notes. Omit note_key for the paginated inventory; supply an exact returned key to retrieve one. Keys retain source scope because printed markers may repeat. This tool does not infer ownership by a provision. Historical versions return an explicit version_not_served link.

Input Schema

TableJSON Schema

Name	Required	Description
`limit`	No	Notes per page, default 10; complete bodies are never truncated.
`cursor`	No	Continue with the same arguments; bound to this corpus release.
`note_key`	No	Exact key returned by this tool. Omit to list notes. Printed markers may be reused and are not necessarily unique keys.
`version_id`	No	Omit or use current for the served version; pinned versions return an explicit version_not_served link.
`instrument_id`	Yes	Registry instrument id.

TDQS

A4.7/5.0

Behavior5/5

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

Annotations already cover read-only/idempotent/non-destructive, and the description adds real behavioral context beyond them: keys retain source scope because printed markers may repeat, the tool does not infer ownership by a provision, and historical versions return an explicit version_not_served link. These are non-obvious traits an agent needs.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

Five tight sentences, each carrying distinct information, with the core purpose front-loaded and mode selection immediately after. No filler or restatement of the name.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness5/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

With an output schema present and annotations covering the safety profile, the description supplies the remaining essentials: paging vs. single-note modes, key semantics, the non-inference caveat, and historical version behavior. Nothing needed to call it correctly is missing.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters4/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema coverage is 100%, so baseline is 3, but the description adds meaning: why note_key should be omitted vs. supplied, and why the key format matters (markers can repeat, so keys carry source scope). It does not elaborate on limit/cursor/version_id beyond the schema text.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

States a specific verb (read) and resource (original legislative footnotes/source-note bodies) and scopes it to a held instrument, including preamble and annex notes. This is clearly distinguishable from siblings like get_provision or get_instrument, which return other content.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines4/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description gives explicit conditional usage: omit note_key to get the paginated inventory, supply an exact returned key to retrieve a single note. It does not name alternative tools or state when not to use this one, so it falls short of full routing guidance.

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