open_workspace

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

With no annotations, the description must disclose behavior itself. It reveals persistence but not what opening or initializing does: whether it creates files, changes state, is idempotent, or modifies an existing directory. For a tool that may initialize (write) a workspace, this is a substantial transparency 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 one concise sentence with the action front-loaded and no filler. It could earn a 5 if it added crucial path/behavior details without padding, but as written it is brief rather than optimally informative.

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?

Despite the tool's low parameter complexity, the complete absence of parameter documentation, annotation coverage, and output schema means the description must carry the full context. It omits return behavior, path semantics, and side effects of 'initialize,' leaving an agent with only a vague idea of how to invoke it correctly.

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 single required parameter 'path' has zero schema description coverage, and the description never mentions it. The agent cannot infer whether path is a directory, a file, a repository, or a remote reference, or what constraints apply.

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 uses a clear verb ('Open or initialize') and identifies the resource type ('persistent multi-paper workspace'), which separates it from sibling paper-level tools like load_paper and workspace_add_*. It is slightly vague about whether initialization creates a new artifact or opens an existing one, but the core purpose is recognizable.

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?

No guidance indicates when to call this tool versus the many workspace_* and paper-loading siblings. The phrase 'Open or initialize' implies it should precede paper operations, but the description never states this precondition or mentions any alternative.

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