Update Accrual

brc_update_accrual

Destructive

Updates an accrual using its current concurrency timestamp. Requires a valid routeToken issued for the matching action workflow. The token remains valid through lookup, preview and the permitted transaction. Placeholder tokens are invalid. A routeToken does not bypass preview or explicit-confirmation requirements. A call without confirmWrite: true returns confirmation_required and a payload preview. confirmWrite: true applies the previewed change after explicit confirmation. Passing preflight is not confirmation.

Tool call template

Replace each placeholder with a value matching the input schema. Only required parameters are included; add optional parameters as needed.

Input Schema

Name	Required	Description
`id`	Yes	Parent accrual id.
`total`	Yes	Accrual total amount.
`acCode`	Yes	Nominal account code, for example 4000.
`procDate`	Yes	Processing date, for example 2024-03-15T00:00:00.
`entryDate`	Yes	Entry date, for example 2024-03-01T00:00:00.
`reference`	Yes	Accrual reference, for example ACC0001.
`timestamp`	Yes	Base64 timestamp returned by the accrual, for example K94UQIbL3gg=.
`routeToken`	Yes	Opaque routeToken from brc_route_request for this action workflow. Required for transactional tools. Routing permission only — does not replace preview-before-posting or confirmWrite.
`companyName`	Yes	Company context name, for example YOUR-COMPANY-NAME.
`firstDetail`	No	First detail text.
`confirmWrite`	No	Must be true only after the user explicitly confirms updating this accrual.
`secondDetail`	No	Second detail text.
`connectionRef`	No	Opaque Red connection reference returned by brc_confirm_company_connection. Pass this exact value on every later tool call when the MCP client rotates session ids (for example Vibe/Mistral). Keep reusing the same connectionRef after successful tool calls — do not start a new connection because a lookup returned empty or partial data. It is not an API key and does not contain credentials.

A4.8/5.0

Behavior5/5

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

Beyond the annotations (readOnlyHint=false, destructiveHint=true), the description explains the two-phase confirmWrite behavior, what happens without confirmWrite, that preflight is not confirmation, and that placeholder tokens are invalid. This is rich behavioral context that helps the agent avoid unsafe calls.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

Every sentence earns its place. The description front-loads the core action, then covers token requirements and confirmation semantics without filler or repetition of schema-only details.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness5/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Given the dangerous mutation, 13 parameters, 9 required fields, and no output schema, the description covers the critical interaction flow: token acquisition, preview behavior, confirmation, and the confirmation_required response. Nothing essential for safe invocation is missing.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters5/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema coverage is 100%, but the description adds significant meaning beyond the schema for the tricky parameters: timestamp is framed as a concurrency control value, routeToken's lifecycle and limitations are clarified, and confirmWrite's exact call behavior is specified. This goes well above the baseline for high schema coverage.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

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: 'Updates an accrual using its current concurrency timestamp.' It clearly distinguishes this from sibling create/delete/get accrual tools by emphasizing concurrency control and the routeToken workflow.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines4/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description gives explicit preconditions: a valid routeToken for the matching workflow, the token's validity window, and the requirement for explicit confirmation via confirmWrite. It does not explicitly name alternative tools or state when not to use the tool, so it falls just short of a 5.

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