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

Annotations already declare destructiveHint=true, openWorldHint=true, idempotentHint=false, so the risk profile is known. The description adds the two confirmation gates and that channel resolution is internal, but says nothing about what happens on a repeat call to an already-configured store — an important omission for a non-idempotent, destructive tool.

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, verb-front-loaded, no filler paragraphs. The final clause 'Requires HGRApi Header channel / ChannelOAuthId resolved internally' is jargon-heavy and partially redundant with the schema, but the definition is compact overall.

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?

With an output schema and fully documented annotations, the description needn't explain return values, and it does cover the confirmation gates. It is still thin on the side effects of a destructive, non-idempotent create on a store that already has an AI Publisher agent configured.

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 coverage is 100% and each parameter already carries a detailed description, so the baseline is 3. The description restates the confirmation flags and adds 'ChannelOAuthId resolved internally', which mildly conflicts with the schema framing of channelOAuthId as a value returned by hgr_list_channels, so it does not add net clarity.

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+resource ('Creates/activates the default AI Publisher automation') and scopes it to 'one visible store', which is concrete. It does not distinguish itself from the nearby sibling hgr_change_ai_publisher_status, so an agent must infer which is the create path versus the status-toggle path.

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?

Gives prerequisites ('Requires confirmed=true and impactConfirmed=true') and points at hgr_list_channels as the source of channelOAuthId, which is a useful workflow hint. However it never says when to use this versus hgr_change_ai_publisher_status, nor what to do if an agent already exists, so usage is only implied.

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