fow_audit_phase

Compare current requirement traceability against a scope's prior snapshot and save the phase audit as a durable local job for later review.

Instructions

Compare current requirement traceability with the previous snapshot of a named scope and retain the resulting phase audit as a durable local job. Single operation; call directly without an operation argument. Prerequisites: Use a defined requirement scope; retain the same requirement selection when reusing its scope_id. Effects: Schedules a durable local audit of traceability changes since the prior scope snapshot. No model/provider call or lifecycle transition; audit evidence is distinct from acceptance. Exact help (replace operation_name with the selected route): fow_capabilities({"view":"operation","operation_tool":"fow_audit_phase","operation_name":"call"}).

Input Schema

TableJSON Schema

Name	Required	Description
`actor`	Yes	Identity of the human or agent recording this action; retain the original identity when replaying its request.
`scope_id`	Yes	Named audit/work scope selecting the relevant requirement phase or work projection.
`project_id`	Yes	Canonical lifecycle project ID. Select the existing project explicitly; development Markdown authorities are separate from runtime projects.
`request_id`	No	Caller-owned retry identity. For receipted mutations replay the same actor and contents; changed contents can conflict. Inspect exact operation help for its receipt policy.
`requirement_ids`	No	Explicit existing requirement IDs defining the selected scope.

A3.9/5.0

Behavior4/5

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

Beyond the annotations, the description discloses that it schedules a durable LOCAL job, makes no model/provider call, performs no lifecycle transition, and that audit evidence is distinct from acceptance. This meaningfully expands on destructiveHint=false/readOnlyHint=false, though it stays silent on idempotency/replay behavior despite idempotentHint=false.

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

Conciseness4/5

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

Front-loaded with purpose, then Prerequisites and Effects blocks that are easy to scan. The final fow_capabilities help-pointer line is slightly meta/verbose but every other sentence earns its place.

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

Completeness4/5

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

For a mutation-style job-scheduling tool, the description covers prerequisites, effects, and scope semantics, and an output schema exists so return values need no explanation. Only the retry/idempotency story (relevant given idempotentHint=false) is left largely to the schema's request_id field.

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

Parameters3/5

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

Schema description coverage is 100%, so the baseline is 3. The description adds only marginal value for parameters, mainly the scope_id reuse constraint ('retain the same requirement selection when reusing its scope_id'); it does not explain requirement_ids or request_id beyond what the schema already documents.

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

Purpose4/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description states a precise verb and resource: 'Compare current requirement traceability with the previous snapshot of a named scope' and clarifies the output is a retained phase audit. It is specific enough to distinguish itself from passive read siblings like fow_traceability, though it never names an alternative explicitly.

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?

'Single operation; call directly without an operation argument' plus a Prerequisites line ('Use a defined requirement scope; retain the same requirement selection when reusing its scope_id') gives clear invocation context. It does not name a competing sibling tool or state when NOT to use it, so it stops 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.
