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

No annotations are supplied, so the description must carry the behavioral burden. 'List' implies a read-only, non-destructive operation and the sentence reveals the metric set returned, but it says nothing about pagination, whether closed/stopped copies are included, or any auth/scope constraint on 'your'.

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 nine-word sentence with zero waste and the key qualifier ('your paper fund copies') front-loaded. It is a fragment rather than a sentence, which slightly weakens the opening.

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 an output schema present and no parameters, the description need not explain return values, and it doesn't. However, it leaves open whether stopped/closed copies appear and how this differs from the many per-copy get_* siblings, which is the main thing an agent needs to route correctly.

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?

The tool takes zero parameters, so the baseline is 4. The description adds no parameter filler, which is appropriate; there is simply nothing for it to disambiguate.

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?

Names the resource precisely ('your paper fund copies') and the payload it returns (live equity, P&L, allocation). The implicit verb is 'list', and 'your ... copies' distinguishes it from list_funds / get_fund, though the absence of an explicit verb keeps it from being maximally crisp.

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 when-to-use guidance and no named alternative. An agent cannot tell from the text whether to call this versus get_fund_copy_state, get_fund_live_pnl, or list_funds — it must infer the scope from 'your' alone.

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