get_company_timeline

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

No annotations are provided, so the description carries the full behavioral burden, and it discloses almost nothing: no mention of what counts as an 'event' (name changes, board changes, bankruptcies?), no ordering, no result volume, no pagination, no auth requirements. Only the read-only nature is inferable from the verb 'Get'.

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?

A single front-loaded sentence with zero filler or repetition. It is lean to a fault, but no sentence is wasted.

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?

With no annotations, no output schema, and no explanation of event types, result size, or temporal ordering, the definition leaves the agent unable to predict what it will get back. For a timeline tool the notion of 'event' is the core concept and is entirely undefined.

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 description coverage is 100% — orgnr format/examples and the lang enum are fully documented in the schema, so the baseline of 3 applies. The description adds nothing beyond 'Swedish company', which merely reinforces the schema's existing org-number semantics.

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?

The description pairs a specific verb (Get) with a specific resource (historical events / timeline) and a scope (Swedish company). This distinguishes it implicitly from financial-data siblings like get_annual_reports or get_compliance_data, but it never names or contrasts with any sibling explicitly.

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?

There is no guidance on when to use this tool rather than lookup_company, get_annual_reports, or get_compliance_data, all of which plausibly overlap with 'historical events'. The agent must infer the boundary entirely from the sibling names.

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