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

With no annotations, the description carries the behavioral disclosure burden. It explains the two accepted source forms (file path or docker:container_name), that it scans and counts trades/errors/signals, and exactly what fields it returns, including an optional error field. It does not discuss permissions or max_errors behavior, but the read-only 'scan' framing plus detailed return contract gives a strong behavioral picture.

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?

The description is compact and front-loaded with the core purpose, followed by useful path syntax and return fields. The return-dict list is slightly redundant given that an output schema exists, but the overall structure is efficient and easy to scan.

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?

An agent can successfully invoke the tool based on this description: the required parameter format is clear, the optional parameter has a schema default, and the return contract is specified. The main gaps are undocumented max_errors semantics and lack of explicit sibling differentiation, but the core invocation path is well covered.

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 0%, so the description must compensate. It does explain logs_path well, including the file-or-docker format with an example. However, max_errors is never mentioned, leaving its effect on recent_errors and counts to inference.

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 states a specific verb and resource: 'Scan Freqtrade logs for trades / errors / signals.' It also lists the return contract, which makes its purpose unmistakable and distinguishes it from siblings like trade_signal or backtest_report even without naming them.

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?

The intended use is implied by the description — it scans Freqtrade logs — but there is no explicit guidance on when to prefer this tool over alternatives, nor any exclusions or when-not-to-use conditions. The context is clear, but the tool is not positioned against its siblings.

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