saveFixItems

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

Beyond the annotations, the description discloses that this overwrites existing items for the same page/field, that the fix list is hand-authored and non-reproducible, and that blank/unchanged values are treated as removals upstream. However, there is an internal inconsistency: it says a note may leave proposedValue blank, but later says a blank value is rejected here, which slightly clouds the behavior.

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 well-structured: purpose first, overwrite warning second, validation and alternative tooling last. Every sentence carries operational weight, and the critical caveats are front-loaded.

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, non-reproducible write operation, the description covers read-before-write behavior, user confirmation, validation rules, and the correct deletion alternative. The only notable gap is the unresolved contradiction about whether a note with a blank proposedValue is actually accepted.

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 auditId, pageUrl, items, and proposedValue semantics. The description adds the upstream-removal context and validation rationale, but it largely restates the schema and introduces the blank-note ambiguity, so it does not unambiguously improve parameter understanding.

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 opens with a specific verb and resource: 'Record proposed metadata changes for one page of an audit — the developer handoff list.' It clearly identifies the write operation and the narrow scope, and it differentiates the tool from its siblings by mentioning listFixItems and deleteFixItem.

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 explicitly tells the agent to read with listFixItems first and confirm with the user before replacing entries, and it directs deliberate removals to deleteFixItem. This is exactly the when-to-use / when-not-to-use guidance needed for a destructive hand-authored tool.

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