trace_complete

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

Adds behavioral context beyond annotations: states trace becomes immutable and available for audit. Consistent with destructiveHint=false, providing useful side-effect info.

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?

Highly concise with clear structure: summary line, explanation, then Args/Returns. No redundant content.

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?

Adequate for a simple tool with one parameter and output hint, but lacks details like preconditions (e.g., cannot complete already completed trace), error handling, or relationship to 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?

Single parameter trace_id described as 'ID of the trace to complete,' which adds minimal meaning beyond schema (title 'Trace Id'). No format or example provided.

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?

Clearly states the tool marks an execution trace as complete, using specific verb and resource. Distinguishes from siblings like trace_step and trace_create by explicitly focusing on finalization.

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?

Implies usage context: finalizing a trace to make it immutable and audit-ready. However, lacks explicit when-not-to-use or alternatives, though no direct sibling conflicts.

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