get_hl_copy_trade_tx_list

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

Annotations already establish readOnlyHint=true and openWorldHint=true, so the safety profile is covered. The description adds real operational context beyond that: session-key auth is required, results are cached for 15s, and page size caps at 100. It omits what happens with a missing/expired session key, but the added traits are substantive.

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?

Four terse sentences, front-loaded with the core purpose, followed by pagination, auth, and caching facts. No filler and nothing buried.

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?

For a read-only, annotation-covered list tool with a fully documented schema and no output schema, the description supplies the missing operational pieces: auth requirement, cache window, and page cap. The main gap is the absence of routing guidance against the many similar history/list siblings.

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%, so the schema already documents data, page, limit, userId, and accountRef. The description only restates the limit cap ('max 100 per page') and adds no meaning about the encrypted session key or accountRef flow. Baseline 3 applies when the schema does the heavy lifting.

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?

States a specific verb and resource: 'Get HL copy trade fill history'. An agent can identify it as the HL copy-trade fill-history reader. It does not explicitly distinguish itself from near-neighbors such as get_copy_trade_tx_list, hl_tx_list, or get_hl_trade_history, so it falls short of a 5.

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?

No when-to-use guidance and no named alternative. The agent gets no signal on when this beats get_hl_trade_history, hl_tx_list, or get_copy_trade_tx_list, which all live in the same sibling set. Only implicit usage is conveyed by the name.

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