Agent Decision & Evidence Tools (MCP + x402)

EU AI Act disclosure evidence

ai_act_disclosure

Read-only

Create a signed Article 50 provenance record and German/English disclosure for AI-generated content, including a privacy-first hash-only path. This attests declared origin; it does not detect AI in arbitrary content.

TDQS

A4.1/5.0

Behavior4/5

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

The description adds useful behavioral context beyond annotations: the privacy-first hash-only path and the limitation that it attests declared origin rather than detecting AI. The word 'Create' is slightly ambiguous against readOnlyHint, but it reads as generating a returned artifact rather than mutating persistent state.

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?

Two sentences with no filler. The primary action and resource are front-loaded, and the second sentence earns its place by preventing a common misuse case.

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

Completeness4/5

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

The description provides enough domain context for tool selection and communicates the privacy and limitation boundaries. The output schema covers return values and annotations cover read-only/idempotency, leaving only parameter-level semantics underspecified.

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

Parameters2/5

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

Schema description coverage is 0%, so the description must compensate, but it names none of the seven parameters explicitly. 'German/English disclosure' hints at the language parameter and 'hash-only path' hints at content_sha256, but kind, model, deployer, content, and model_provider receive no explanation.

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 concrete action and resource: creating a signed Article 50 provenance record and German/English disclosure for AI-generated content. It also clarifies a non-goal—this does not detect AI in arbitrary content—which meaningfully distinguishes it from other tools.

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 intended use is clear from the first sentence: use this when a provenance/disclosure record is needed for declared AI origin. The second sentence provides an explicit exclusion for arbitrary-content AI detection, though it does not name a specific sibling alternative.

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