Find an EU payments reading pathway

get_orientation

Read-onlyIdempotent

Use this for a starting reading order in EU payments legislation when a relevant curated pathway exists. For other subjects use search_legislation. Curated reading pathways into the corpus for a stated audience: ordered waypoints with cite anchors every other tool can open, related defined terms and known pitfalls. The prose is editorial and labelled as such — it maps the reading order, never legal weight. Omit the pathway argument for the catalogue; an unknown id is refused with the catalogue, nothing substituted. Catalogue entries and pathway waypoints paginate whole: follow pagination.next_cursor with the same pathway and limit until complete.

TDQS

A4.9/5.0

Behavior5/5

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

Beyond the readOnly/idempotent annotations, the description explains the content shape (ordered waypoints, cite anchors, related defined terms, known pitfalls), the editorial non-legal nature of the prose, and safe pagination behavior. It also discloses failure semantics: an unknown id is refused with the catalogue, nothing substituted.

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?

Every sentence carries operational or conceptual weight: usage condition, alternative tool, output nature, catalogue behavior, and pagination contract. The description is dense but not padded, and the most important selection guidance is front-loaded.

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?

Given the tool has an output schema, the description does not need to explain return values. It covers when to use the tool, how to identify curated pathways, how to avoid the legal-weight misunderstanding, and the complete pagination loop. No critical caller-facing gap remains.

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 the baseline is 3. The description adds meaning beyond the schema by clarifying that an unknown pathway id is refused, that pagination must reuse the same pathway and limit, and that catalogue entries and waypoints paginate as whole items. These details help an agent invoke the parameters correctly.

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?

The description states a specific purpose: finding a starting reading order in EU payments legislation via curated pathways. It also names the broader catalogue behavior and explicitly differentiates from search_legislation, so an agent can distinguish this tool from its siblings without opening schemas.

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

Usage Guidelines5/5

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

It gives an explicit condition for use ('when a relevant curated pathway exists') and an explicit alternative ('For other subjects use search_legislation'). It also provides concrete operational guidance: omit the pathway argument for the catalogue, and treat unknown ids as refused rather than substituted.

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