get_legal_timeline

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

Adds context beyond annotations by noting it is a research tool with primary-source citations and disclaimers about legal advice. Annotations already declare readOnlyHint=true, so the description reinforces safe read-only behavior.

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?

Description is extremely concise with two sentences that convey the core purpose and key caveats, front-loaded with the main action. No wasted words.

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?

Given the tool has only one required parameter and no output schema, the description sufficiently covers what the tool does and its non-legal nature. Could be enhanced by hinting at the output format, but overall adequate.

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% for the single parameter 'celex'. The description does not add extra meaning beyond what the schema provides (e.g., example value), so baseline score of 3 is appropriate.

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?

Clearly states the tool returns an application-date timeline for a major EU act with staggered obligations, exemplified by the AI Act high-risk deadlines. It uses specific verb 'timeline' and resource 'EU act', distinguishing it from the sibling 'get_knowledge_article'.

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?

Mentions 'Free — no API key required' but does not explicitly state when to use this tool versus the sibling 'get_knowledge_article' or provide circumstances where it should not be used.

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