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

The annotations already indicate this is a mutating operation (readOnlyHint=false) in a closed world (openWorldHint=false). The description adds useful context by noting the outcome must be public-safe and listing the three outcome values, but it omits operational details such as append semantics, idempotency, permissions, and the role of append_key.

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?

The description is a single front-loaded sentence with no redundant wording. Every part of the sentence contributes to identifying the action, the allowed outcomes, or the target post.

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 mutating tool with five parameters, zero schema descriptions, and no output schema, the description is too sparse. It does not explain required parameters like append_key, does not clarify usage relative to siblings, and does not describe append behavior or authorization requirements.

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 0% across 5 parameters, so the description must compensate. It only clarifies the outcome enum values and implies that the note is public-safe; it leaves thread_id, append_key, and request_key unexplained, including the required append_key.

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 uses a specific verb (append), names the resource (outcome), and states the exact allowed values (resolved, partial, failed). It also identifies the target as the search post returned by search_skills, but it does not distinguish this tool from the sibling resolve_post, which likely also acts on posts.

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 explicit guidance on when to use this tool versus alternatives such as resolve_post. The reference to search_skills explains where thread_id comes from, but not when an outcome should be reported or when it should not.

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