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

Beyond the annotations, the description discloses important behavioral details: it unstamps the previous Fixed state, returns the card to pending, does not mint a sibling remint, refuses certain Fixed types, and may require manager approval on first use. The description is consistent with destructiveHint=true and readOnlyHint=false.

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 stays dense throughout. Every clause adds behavioral or operational value: allowed false-Fixed cases, resulting statuses, exclusions, membership requirement, and approval handling. It is longer than average, but the complexity justifies the length.

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?

Given the tool's write/destructive nature and no output schema, the description covers the key operational context: what action is performed, what statuses result, when the tool refuses, who may use it, and how approvals behave. An agent has enough information to select and 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 description coverage is 100%, so the schema already documents companyId and request_id. The description adds little parameter-level detail beyond emphasizing that the request_id must be the same product request, which is helpful but not a significant extension over the 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 precise verb ('Unstamp a false Fixed'), a specific resource ('the SAME FreedomOS product request'), and the resulting state ('Returns the card to pending with product_status queued or pr_open'). It also distinguishes itself from related operations by explicitly saying it 'Does not mint a sibling remint', so an agent can tell it apart from nearby sibling tools.

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 gives an explicit when-to-use condition: 'Use when a product request was stamped Fixed without a verified class fix and you need to reopen that same request_id.' It also provides clear when-not-to-use signals: it 'Refuses deploy-verified / auto-shipped Fixed' and restricts use to 'FreedomOS product-inbox members only', plus the write-tier approval note explains the approval flow.

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