Check EU AI Act Implementation Deadlines

euaiact_check_deadlines

Read-onlyIdempotent

Check EU AI Act deadlines and milestones with days remaining, next milestone, upcoming-only filter, and Digital Omnibus status.

Instructions

Returns key implementation milestones and deadlines for the EU AI Act with days remaining, a next_milestone shortcut, and a summary of the Digital Omnibus. The milestone timeline always reflects the operative law. Set include_pending_omnibus: true to also receive the structured Digital Omnibus pack (each item source-status labelled; its status and enacted fields carry the current legislative state). Use only_upcoming: true to drop past milestones.

Input Schema

TableJSON Schema

Name	Required	Description
`area`	No	Optional filter by compliance area (e.g. 'GPAI', 'high-risk', 'prohibited')
`only_upcoming`	No	If true, return only milestones that have not yet come into effect.
`include_pending_omnibus`	No	If true, also return the structured Digital Omnibus pack with per-item source-status labels. OFF by default: the milestone timeline always reflects the operative law only. Check the pack's `status` and `enacted` fields for its current legislative state; non-enacted content must not be treated as current law.

A4.1/5.0

Behavior4/5

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

Annotations already declare readOnlyHint, idempotentHint, and openWorldHint=false, so the safety profile is covered. The description adds real behavioral value beyond that: the milestone timeline 'always reflects the operative law', and the omnibus pack items are source-status labelled with `status`/`enacted` carrying legislative state. It does not discuss pagination or result volume, but read-only status is well established.

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

Conciseness4/5

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

Front-loaded with the return payload in the first sentence, then behavior and option semantics. Four sentences, each carrying information, though the omnibus caveat is repeated in the schema and could be tighter. No filler.

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?

With an output schema present, the description needn't explain return values, and annotations cover the safety profile; the remaining burden (operative-law semantics, pending omnibus labelling, option effects) is addressed. Only the `area` filter's behavior is left entirely to the schema, a minor gap for a fully documented read tool.

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

Parameters3/5

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

Schema description coverage is 100%, so the schema already documents area, only_upcoming, and include_pending_omnibus, and the schema's own include_pending_omnibus text already states the operative-law default. The description largely restates this, adding marginal semantics, so the baseline of 3 is appropriate.

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 precise verb and resource ('Returns key implementation milestones and deadlines for the EU AI Act') and enumerates the payload contents (days remaining, `next_milestone`, Digital Omnibus summary). This clearly distinguishes it from siblings like euaiact_get_obligations or euaiact_calculate_penalty, which serve different intents.

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?

It gives clear conditional guidance for the options ('Set `include_pending_omnibus: true` to also receive...', 'Use `only_upcoming: true` to drop past milestones'), which is effectively when-to-use guidance. It stops short of naming alternatives or when-not to use this tool, but given the sibling set covers unrelated tasks the routing is unambiguous.

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