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

Annotations only declare readOnlyHint=false, openWorldHint=true, destructiveHint=false — the mechanically checkable facts. The description goes beyond them with substantive context: publication is opt-in, anonymization redacts project/repo, and exactly what third parties can see (requirements + matrix only). It omits reversibility/visibility scope details, keeping it short of a 5.

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?

A single dense sentence with the value proposition and the consent model front-loaded before the privacy guarantee. Slightly telegraphic phrasing ('Free:', 'requirements + matrix') but no wasted sentence.

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?

One required parameter, full schema coverage, and an output schema, so return values need no explanation. The description supplies the privacy/visibility framing an agent needs for a write operation with open-world reach; only the reversibility story (via unpublish) is unstated.

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?

Only one parameter, and the schema already documents it fully (coverage 100%) including the 'fm_… id from capture_feature or list_feature_memory' provenance. The description adds nothing about the parameter beyond that, so the baseline 3 applies when the schema carries the semantics.

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 (publish) and resource (a captured feature to the anonymized community library), plus the effect (project/repo redacted, others see requirements + matrix). The verb+resource pair and the 'captured feature' input make it distinguishable from capture_feature and unpublish_feature_pattern, though it never names those siblings directly.

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?

'Opt-in' and 'Free' together imply the user-consent precondition for calling this, which is real guidance about when it is appropriate. However, there is no explicit statement of when to prefer this over list_community_patterns or how it relates to unpublish_feature_pattern, so routing is left to inference.

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