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

Annotations already declare idempotentHint=true, destructiveHint=false, and openWorldHint=false, so the safety profile is covered. The description adds only "privacy-filtered project metadata," which hints at what data may be supplied but says nothing about the actual conversion behavior, whether it is reversible, or what happens on a version conflict.

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?

It is a single short sentence with no padding, which is good, but it is under-specified rather than genuinely concise — the words "hosted convert" consume the limited space without resolving the core ambiguity.

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 7-parameter mutation with a nested object, required idempotency and versioning fields, and no output schema, one sentence is inadequate. Nothing explains the conversion semantics, retry/conflict expectations, or the effect on the target note.

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 baseline is 3; the schema documents all 7 parameters including idempotencyKey and expectedVersion. The description adds no parameter-level meaning beyond the vague reference to "privacy-filtered project metadata," which loosely maps to the nested details object but conveys nothing new.

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?

It names a verb (update) and a resource (context note), but the qualifier "convert" is never defined, so an agent cannot tell what is actually being converted or how this differs from the sibling update_context_note. The phrase "hosted convert context note" reads as a name restatement rather than a clear statement of purpose.

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?

There is no indication of when to use this tool versus update_context_note, archive_context_note, or move_context_note, all of which operate on the same resource. No prerequisites, no exclusions, no alternative named.

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