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

Beyond the annotations, it discloses that credits are spent, only the character slot is patched, the previous approval is cleared, retries are safe with the same planId, and approval must wait for the user. This adds real operational context on top of destructiveHint, idempotentHint, and openWorldHint.

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 dense and mostly front-loaded, though it opens with setup/auth instructions before the core action. Every sentence carries useful information, with no filler.

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 destructive, credit-spending mutation with no output schema, the description covers auth, cost, idempotency, approval clearing, downstream polling, and the user-approval gate. An agent has everything needed to invoke it correctly.

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 100%, and the schema already explains that planId comes from plan_style_sheet_character_edit. The description only reinforces reuse of the same planId for retries, so it adds little beyond the structured field.

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 states a specific verb and resource: it queues the character-region change produced by plan_style_sheet_character_edit and patches only the character slot into the current Style Sheet. It is clearly distinguishable from the planning sibling and from approve_design_sheet.

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?

It makes the workflow explicit: obtain the plan first, retry only with the same planId, then poll get_style_sheet_character_edit_status, show the revised image, and call approve_design_sheet only after explicit user approval. Prerequisites (approved AlertForge connection, OAuth sign-in) are stated up front.

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