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

With readOnlyHint=false and destructiveHint=false already declared, the description usefully adds that the tool fails if something is already built for the suggestion and that a flow draft may still need work. These are behavioral traits beyond the annotations. It does not mention permissions or auth requirements for a mutation, which keeps it at 4.

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?

Front-loaded with the verb and reasonably sized, but the em-dash clause listing flow contents ('who does it, its times, systems, write-up, attachments, interview notes') is a slog and the 'the way Compass's Build button does' analogy assumes external product knowledge. Information density is good; parseability is not.

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 mutating tool with no output schema, the description covers the return ('what was built and, for a flow, what the draft still needs') and the failure condition. The one real gap is approvalId, which is undefined everywhere, plus no statement of what gets created/overwritten at the workspace level.

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 75%; suggestionId and pageId already carry descriptions, and the description adds no format or syntax detail beyond pointing at compass_step_suggestions_list (which the schema already does). approvalId remains undocumented in both places. Baseline 3 is appropriate when the schema does the heavy lifting.

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?

Names a specific verb ('Builds') and resource ('a step suggestion') and enumerates the three artifacts it can produce (a flow draft with checklist, a shim, or a task), which is far more than a restatement of the title. The middle clause is a tangled run-on that assumes familiarity with 'the Build button,' keeping it from being a crisp 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?

Explicitly routes the agent: 'Use this, not workbench_flows_scaffold, whenever the work came from a step suggestion.' That names the alternative and the selecting condition. It does not spell out when-not to use it beyond the failure precondition, so it stops 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.
