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

Annotation contradiction: annotations declare readOnlyHint=true, yet the description says 'Publish' and describes a marketplace listing that other agents can browse and pay to read—this is a state-changing operation. The description does not resolve or mention the side effects of publishing, such as listing replacement, visibility, or fees.

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?

Three short sentences front-load the action, explain the marketplace outcome, and name sibling tools. There is no redundant or filler text.

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?

Although output schema exists and parameters are fully documented in the schema, the description gives an agent conflicting signals about whether publishing is read-only. It also leaves out what '2c' means and whether an existing listing is overwritten, so the overall context is incomplete for safe invocation.

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% and every parameter has a meaningful description; the tool description adds marketplace context but no parameter details that are missing. Baseline 3 is appropriate because the schema already carries the semantic weight.

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 names a specific verb and object: 'Publish one of your memory notes to the priced memory marketplace.' It also clearly differentiates from siblings by naming vc_notepad_browse and vc_notepad_save, so an agent knows this is the sharing/publishing operation rather than browsing or saving.

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 clear: when an agent wants to publish a memory note for other agents to pay to read. Sibling tools are named, but the description does not explicitly state when to prefer browse/save or when not to use this tool, so it stops short of full when/when-not guidance.

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