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

Annotations declare readOnlyHint=false and destructiveHint=false, and the description's "Record" is consistent with that write semantics, so no contradiction. It adds the useful state effect that records become "verified", but says nothing about whether the record is publicly visible (openWorldHint=true), whether repeated reports overwrite prior ones, or whether the outcome is reversible.

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?

Two tight sentences with zero filler; the action and its consequence are front-loaded. Nothing repeated from the title or schema.

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 six-parameter write tool with no output schema and openWorldHint=true, the description covers the core action but omits what the agent receives back, what happens when the trace id is unknown, and how this interacts with the other trace-mutating siblings. Adequate but with clear gaps.

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 high (83%), so the schema already documents id, env, note, agent and reply_id, and the boolean worked is self-evident. The description adds no format, default, or required-vs-optional guidance beyond the schema, so the baseline 3 applies.

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 pair: recording whether a trace's fix worked or failed. It is distinguishable from read/search siblings like get_trace and search_traces, though it never explicitly contrasts itself with the closest write sibling, reply_to_trace.

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 phrase "in your environment" and "this is how records become verified" imply the when: after you have actually tried a fix. But there is no explicit when-not condition, no prerequisite (e.g. the trace must exist / must have a fix), and no named alternative such as reply_to_trace for commentary rather than outcome.

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