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

Goes well beyond the annotations: it discloses that every SKU is re-read live and skipped if the listing changed since the preview, that a batch halts if the prior batch is not confirmed applied, and that the prior value is persisted to a registry for title_seo_rollback. These are exactly the write-safety and reversibility facts an agent needs before invoking a destructiveHint=true tool.

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?

Three sentences, front-loaded with the tool's role and write nature, then the batching rules, then the live-verification and rollback guarantees. No filler and no repetition of the schema.

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 batch-write tool with no output schema, the description covers prerequisites, size limits, abort conditions and rollback. What it omits is what a partial or halted batch returns to the caller (per-SKU success/failure, which SKUs were skipped), which matters for a batch operation.

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%, so the baseline is 3; the description nonetheless adds operational meaning by tying the batch-size ceilings (2 then 50) to the skus parameter and clarifying that the batch is drawn from the plan's ready set. It adds real constraint information rather than restating field descriptions.

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 and resource — applies a batch of a title-SEO plan, write step, ready SKUs only — and labels itself 'passo 2', which positions it against the planning/preview and rollback siblings. It never names plan_title_seo_fix, title_seo_rollback or title_seo_status directly, so the routing is inferable rather than explicit.

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 a clear precondition (a plan must exist, SKUs must be 'ready') and sequencing rules: first batch per outpost is capped at 2 SKUs, later ones at 50, and the previous batch is re-read before continuing. It does not explicitly state 'do not use this to create a plan — use plan_title_seo_fix', leaving the alternative to inference from 'passo 2' and the schema note.

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