A4.2/5.0

Behavior4/5

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

Annotations already declare readOnly/idempotent/non-destructive/openWorld, so the safety profile is covered. The description adds genuinely new behavioral context beyond them: 'Missing currency and tradeability remain unknown' and 'Not guaranteed real-time' disclose data-completeness and freshness limits an agent would otherwise assume away.

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?

Three short sentences, front-loaded with the payload fields and then cabined by caveats and alternatives. The terse caveat sentence ('Missing currency and tradeability remain unknown') is slightly clipped but earns its place by preventing false assumptions.

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?

An output schema exists, so return values need no explanation; annotations carry the safety profile; and the description covers the freshness/completeness caveats plus sibling routing. For a single-parameter read tool, an agent has everything needed to call it correctly.

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%, and the schema already documents the pattern, minLength, and the 'Avanza order-book ID from discovery; not the separate instrumentId' distinction. The description adds no parameter-level meaning beyond the schema, so the baseline of 3 applies.

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?

Starts with a specific verb and resource ('Get fund identity') and enumerates the exact payload fields (NAV, fees, risk, allocations), so an agent knows precisely what comes back. It is clearly distinguishable from siblings like get_fund_chart (raw history) and get_fund_holdings (allocations).

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?

Explicitly routes the agent to alternatives: 'Use get_fund_holdings for allocations only, get_fund_chart for raw history.' It gives clear context for when a sibling is preferred but does not state a positive trigger for choosing this tool over others (e.g. overview/discovery use case).

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