platform_arch_auto_loop

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

With no annotations provided, the description carries the full burden of disclosing behavioral traits. It mentions the actions (list, create, get, execute_action, record_decision) but gives no detail on their effects, side effects, required permissions, or what happens to data. The phrase 'project-scoped Auto Loop runs' adds some scoping context, but it does not explain the consequences of mutation actions like create or execute_action, which is a significant gap.

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 but includes a somewhat redundant opening ('[Arch Optimize] Arch validates...') that provides background context rather than tool-specific instructions. It is not overly long, but the first sentence could be trimmed without losing core information. The action list is useful but not explained. Overall, it is reasonably compact but could be more streamlined.

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?

Given that the tool has five distinct actions with different operational requirements, the description is insufficiently detailed. It does not explain what each action does, when to use which, what parameters are relevant per action, or what the response looks like (no output schema). An agent would struggle to correctly invoke this tool without further clarification, especially for create and execute_action which likely require a body.

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?

The schema covers 75% of parameters with descriptions, and the description lists the actions (the main enumerated values) but does not add meaning beyond the schema. It does not explain what each action does, what body should contain, or how runId is used per action. Since coverage is close to high, the baseline is 3, and the description offers minimal additional value.

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 tool's purpose: it drives Arch Auto Loop repair workflows through the Studio API. The opening line gives context about what Arch does (validates packages, inspects models, drives repair loops), and the list of actions specifies the available operations. It distinguishes itself from siblings by focusing solely on the Arch Auto Loop domain, which is unique among the listed platform_arch_* tools.

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 implies usage for Arch Auto Loop repair workflows but does not explicitly state when to use this tool over alternatives, nor does it mention any exclusions or when-not-to-use conditions. The phrase 'Drive Arch Auto Loop repair workflows' provides a general context, but there is no comparative guidance against siblings like platform_arch_sop or platform_validate_package.

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