Juno Hosting Deploy

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

Annotations already indicate non-readonly and non-idempotent behavior. The description adds useful context about source directory, batch parallelism, and options for clearing/pruning. However, it does not disclose potential consequences like downtime or overwriting, which would be expected for a deployment 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?

The description is two sentences: first sentence states the core purpose, second lists key features. No wasted words, appropriately front-loaded.

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?

The description lacks information about return values (no output schema), prerequisites, and post-deployment behavior. For a tool with 14 parameters, it is somewhat terse but covers the primary action adequately.

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?

With 100% schema description coverage, the schema already documents all parameters adequately. The description briefly echoes batch, clear, and prune but adds no new semantic meaning. Baseline of 3 is appropriate.

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 clearly states the verb (Deploy), resource (app's frontend files to your satellite), and scope (reads from source directory). It distinguishes from sibling tools like juno_hosting_clear and juno_hosting_prune by mentioning them as sub-actions.

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 description does not provide explicit guidance on when to use this tool versus alternatives. It lists supported features but fails to differentiate from siblings like juno_functions_publish or juno_config_apply, nor does it state when not to use it.

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