get_error_log

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

No annotations provided, so description carries full burden. It details the return values including error handling, implying a read-only operation. It does not mention permissions or side effects, but for a zero-parameter tool, this is largely sufficient.

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?

Description is well-structured with sections for description, returns, examples, and best practices. It is concise but the examples section is minimal. No redundant information.

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?

Given zero parameters and no annotations, the description covers the output schema and usage advice thoroughly. It is complete for the tool's complexity.

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?

No parameters exist; schema coverage is 100% vacuously. Baseline for 0 parameters is 4. Description adds value by explaining the output, which indirectly clarifies that no input is needed.

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?

Description clearly states 'Get the Home Assistant error log for troubleshooting', specifying the verb and resource. While it doesn't explicitly differentiate from siblings like get_core_log or get_addon_logs, the focus on errors and troubleshooting provides adequate purpose clarity.

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?

Best practices explicitly state when to use this tool ('when troubleshooting specific Home Assistant errors') and provide guidance on analyzing the log. However, it lacks explicit exclusions or mentions of alternative tools.

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