tf_workspace_init

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

With no annotations present, the description carries the full burden of disclosing side effects and behavior. It says the tool copies/checks out a project into a sandboxed workdir, but it does not state whether an existing workdir is overwritten, whether this operation is destructive, what happens on re-initialization, or whether it creates a new workspace. The term 'sandboxed' hints at isolation but does not clarify the mutation profile.

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 a single efficient sentence with no filler, and the primary action is front-loaded. It is appropriately short for a simple tool, though it is terse enough to omit valuable behavioral details. Structurally it earns its place without redundancy.

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 no annotations, no output schema, and a non-trivial setup operation, the description is incomplete for safe and correct invocation. It does not explain what a successful initialization returns, how the workspaceId relates to the sandboxed workdir, or whether an empty workspace can be created (which the schema's sourceDir description does mention). An agent would need to infer too much about prerequisites and side effects.

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 only 50%, and the description does not compensate for the gap. workspaceId has no description beyond a regex pattern, and the tool description does not clarify its role as the target workspace identifier. sourceDir is explained only in the schema, not in the tool description, so the description adds no parameter-level meaning beyond what structured fields already provide.

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 states a clear action — checks out or copies a Terraform project into a sandboxed workdir — with a specific resource and destination. It distinguishes this setup tool from the planning/apply/write siblings by implying workspace preparation, though it does not explicitly name an alternative. The compound verb 'checks out/copies' is slightly ambiguous but still conveys the purpose.

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 provides no guidance on when to use this tool versus alternatives such as tf_write_file or tf_plan. There is no mention of prerequisites, ordering, or exclusions. The only usage hint is the schema's note about omitting sourceDir to create an empty workspace, which is parameter-level guidance rather than tool-selection guidance.

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