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

No annotations exist, so the description carries the full burden; it discloses the key behavioral traits: nothing publishes without approval, submissions are gated by the Self-Sufficiency Contract, and failures occur at both submit and approval. It does not say what the tool returns, whether ref_id can be resubmitted after rejection, or what permissions are needed, which keeps 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?

Three tight sentences, front-loaded with the action, then the approval consequence, then the gating prerequisite. Dense but every sentence carries information; the contract name slightly obscures the concrete rule it stands for.

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 submission/mutation tool with no annotations and no output schema, the behavioral story is well covered, but the agent still lacks any indication of what a successful response looks like or how to reference/re-submit a rejected item.

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% for three parameters, and the description only partially compensates by implying kind distinguishes 'calculator' vs 'skill' and that ref_id points at a sandbox artifact. The 'notes' parameter is entirely unexplained, and no format expectations for ref_id are given.

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+destination: 'Submit a sandbox calculator or skill to the owner for review.' It also implicitly separates submission from creation (create_calculator/create_skill) and from publishing, so an agent can place it in the workflow.

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 a concrete prerequisite ('run validate_build first and fix any self_sufficient failures') and an exclusion ('a backend-dependent skill is rejected at submit AND at approval'). It does not name get_review_status or resubmission paths as follow-ups, but the when-to-use guidance is explicit and actionable.

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