init_workspace

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

With no annotations, the description carries the full burden. It does disclose two non-obvious behaviors: the workspace is always created at the server-bound root (no path parameter, no user-chosen location), and the profile is a reference only and confers no executable authority — a meaningful safety note for a creation tool. It omits idempotency/conflict behavior, required permissions, and what artifacts get created.

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?

Two sentences, front-loaded with the action and scope; the second sentence adds a distinct security-relevant caveat rather than padding. Slightly dense phrasing ('reference, never executable authority') costs a bit of immediate readability.

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 mutation tool with no annotations, no output schema, and an entirely undocumented parameter, the description should cover failure modes, idempotency, and what a successful initialization produces. It covers root binding and profile authority but leaves the agent unable to predict behavior on re-invocation or on error.

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 the single 'profile' parameter, so the description must compensate. It clarifies that profile is optional and is a non-authoritative reference, but says nothing about its expected form (path, name, identifier) or what happens when it is null versus supplied.

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 gives a specific verb (create) and resource (canonical FCoP 4.0 workspace), and the word 'only' constrains scope so the agent knows this is not a general-purpose initializer. It implies a separation from inspect_workspace/validate_workspace but never names them or states the difference explicitly.

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?

There is no guidance on when to call this versus inspect_workspace or validate_workspace, nor any prerequisite or exclusion (e.g., whether it fails if a workspace already exists, or when re-initialization is appropriate). The only implicit signal is 'only ... at the server-bound root', which constrains scope but not usage timing.

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