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

No annotations are provided, so the description carries the full burden. It correctly discloses that the tool creates and changes projects, agents, tools, configuration, versions, and deployments (a mutating, state-changing tool). It does not contradict anything. But it omits behavioral details like response behavior, required sequence (e.g., creator → upload → message → project), or side effects of the body override. Adequate but not rich.

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?

Four sentences with the action list front-loaded and the critical routing guidance up front. The [Arch Build] tag orients the reader, and the actionable mapping to actions is efficient. Slightly long on the enumerated action list, which partially repeats the schema enum, but overall well-organized and earns its length.

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?

This is a complex compound tool with 8 actions and 12 parameters, and the description guides only 5 of the actions. No output schema exists, so return behavior is nowhere documented. Given the tool's complexity, the description covers the primary workflow well but leaves the auxiliary actions (get_session, continue, recover, cancel) and sequencing details unexplained, which is a notable gap.

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 high at 92%, so the schema already documents most parameters and the baseline is 3. The description adds a modest mapping of text→send_message, file→upload_file, and fileRefs→send_message, which clarifies which params belong to which action. But this is largely redundant with the schema descriptions, so the added value is marginal.

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 clear purpose: driving Arch SOP-build sessions through the Studio API. Lists the 8 distinct actions with specific verbs (create_session, upload_file, send_message, create_project) and describes what Arch does overall. Explicitly differentiates the actions from one another, so an agent knows the tool is a polymorphic driver rather than a single-purpose call.

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?

Provides explicit when-to-use routing for the core actions: create_session for SOP/onboarding or in-project sessions, upload_file for SOP/source files, send_message for SOP-build instructions/fileRefs, and create_project for materializing the project. This is actionable guidance. However, it leaves get_session, continue, recover, and cancel without usage context, and doesn't address how this tool relates to the many debug siblings.

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