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

The annotations already declare readOnlyHint, idempotentHint, destructiveHint=false and openWorldHint=false, so safety is covered structurally. The description's one genuine addition is 'Free' (no credit cost) plus the note that it discloses the only steps a human must do and the limits — useful, but nothing about response size, freshness, or whether it is cached.

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 short sentences, front-loaded with the entry-point directive and then the payload summary. The hyphenated stage list is dense but earns its place by signalling the breadth of the workflow overview; the trailing 'Free' is a small but load-bearing cost signal.

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 no-param, read-only orientation tool with no output schema, the description covers when to call it and roughly what it returns (workflow steps, human-only steps, limits). It could be slightly more explicit that the response is a structured capability document rather than prose, but nothing an agent needs to call it correctly is absent.

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 tool takes zero parameters, so there is nothing for the description to disambiguate; baseline 4 applies. The empty input schema is fully consistent with the described behavior.

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 directive verb ('Describes the whole agent workflow end to end') and enumerates the workflow stages (make, approve, render, publish, automate, pay), which distinguishes it from the sibling action tools. It never literally says 'returns capability/limits data', so the resource is implied rather than stated, which keeps it from a 5.

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?

'Start here' is an explicit entry-point instruction that no sibling can claim, and the workflow-stages list implies the alternatives (the individual make/render/publish tools) it precedes. There is no explicit 'do not use this when...' clause, so it stops just short of a 5.

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