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

Annotations declare readOnlyHint=false, destructiveHint=false, idempotentHint=false, and openWorldHint=true, so the safety profile is already covered. The description adds real value beyond that by disclosing the propagation effect: previously published versions stop being served, and dynamic endpoints referencing @published change behavior. It stops short of saying what happens to the prior live version explicitly or whether re-publishing the same version is a no-op (relevant given idempotentHint=false).

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?

A single sentence that front-loads the action and then the consequence, with zero filler. Every clause (making it live, dynamic endpoints @published) contributes information.

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?

An output schema exists, so return values need no explanation, and annotations carry the safety profile. What the description supplies — the serving semantics and downstream @published effects — covers the main risk of calling this. It could add whether publishing is reversible or how to unpublish, but nothing essential to correct invocation is missing.

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 100% — both workflow_id and version are documented in the schema with clear semantics ('the workflow id to publish', 'the version number to make live'). The description adds no parameter-level detail beyond that, so the baseline 3 applies.

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 specific verb (publish) and resource (workflow version) and then explains the concrete effect: the version becomes the one served to callers. The parenthetical about @published references in dynamic endpoints is a genuinely clarifying detail that separates this from create_workflow_version. It doesn't explicitly contrast with siblings, but the resource is unambiguous.

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?

Usage is only implied: an agent can infer you call this after creating a version and before callers should see it. There is no explicit when/when-not, no statement that the workflow must already have the version created, and no mention of unpublish or rollback alternatives. Adequate but leaves sequencing to inference.

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