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

readOnlyHint=true is consistent (a proposal, not an execution). The description adds real behavioral context beyond the annotation: steps must name real write tools, execute in order only after user approval, and the tool must not be used when there are no writes. It stops short of describing approval/rejection flow or failure handling beyond what the schema notes.

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?

Four sentences, each carrying distinct payload (purpose, trigger, mechanics, negative case), with the primary action front-loaded. No filler or repetition.

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?

With no output schema, the description carries return-value burden, and it adequately explains that a reviewable plan is produced and executed post-approval. It does not detail what the user sees or how rejection is signaled, but for this lifecycle position that is a minor gap.

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 67%, above the baseline threshold, and the description still adds meaning: it explains that each step pairs a tool with its parameters and that steps execute sequentially after approval, clarifying the intent behind the steps array and its ordering semantics.

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+resource ('Produce a structured execution plan') and scopes it precisely to plan mode with concrete write operations. It is clearly distinguishable from siblings like ticket_draft_plan or list_playground_plans, which serve different planning contexts.

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?

Gives explicit when-to-use ('your FINAL action in plan mode when you have concrete write operations to schedule'), an explicit when-not ('If you have no writes to propose, end the turn with plain text'), and a prohibition against an alternative behavior ('Never call write tools directly in plan mode'). Nothing is left to inference.

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