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

Annotations already declare a non-read-only, non-destructive, idempotent write. The description adds important context: it records in Goppa rather than changing the site, and the next site audit checks each page. That resolves the apparent tension between a write tool and 'changes nothing on the site'.

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 front-loaded with the core action and uses only two sentences after it to state the audit consequence and the no-site-change guarantee. It contains 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?

With complete schema coverage, an output schema, and annotations covering safety traits, the description supplies the remaining workflow context: source of fixes, status meanings, and downstream audit behavior. Nothing essential for correct invocation is missing.

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 description coverage is 100%, so the schema already documents site, results, fix_id, reason, and status in detail. The description reinforces the status meanings and the source of fix_id, but it does not add much beyond the structured schema.

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: recording in Goppa which approved SEO fixes from get_fixes_to_apply were applied, not applied, or undone. It names the source sibling tool explicitly, so an agent can distinguish it from retrieval tools like get_fixes_to_apply.

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 clearly implies this tool is used after handling approved fixes from get_fixes_to_apply, with statuses for applied, not_applied, and undone/kept. It does not explicitly state when not to use it or name alternatives, but the workflow context is clear.

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