workspace_create_version_and_publish

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

With no annotations, the description discloses that this is 'the most powerful write operation' that 'goes live in production immediately,' effectively communicating the risk. It also notes required environment variable. Absent mention of reversibility or side effects, but sufficient for a mutation tool.

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 tight paragraph with three sentences: action, prerequisites, and warning. No redundant information; each sentence earns its place.

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?

The tool is complex (create+publication) with high impact and no output schema. The description covers core action, prerequisites, and risk, but omits return value, workspace state implications, and relationship with sibling tools.

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 only 50% (accountId, containerId, workspaceId lack descriptions). The description adds no new parameter details beyond the schema. It mentions confirm but does not elaborate on its role beyond what schema already states.

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 'Create a new container version from a workspace and immediately publish it,' specifying the verb and resource. It distinguishes from siblings like versions_create and versions_publish via the combined action and [PUBLISH] prefix, but does not explicitly contrast them.

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 includes prerequisites (GTM_MCP_ENABLE_PUBLISH=true, confirm=true) and a strong caution about production impact. However, it lacks explicit guidance on when to use this tool versus alternatives (e.g., versions_create for creation-only).

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