Evidence the run may read
- Proposed metric definition
- Source schema and lineage
- Existing semantic and policy definitions
production blueprint · data & analytics
Metric definition review agent blueprint.
Compare a proposed metric with source fields, grain, filters, time rules, and existing definitions before governance approval.

Start from a bounded job, not a blank chat box.

A new or revised business metric enters governance review.

The accountable business and data owners approve the metric definition and publication.
KPI · decrease
duplicate or conflicting governed metrics (metrics). Count active governed metrics with materially overlapping names and inconsistent definitions.
outputs
Artifacts the run must produce
- Definition completeness audit
- Conflict and ambiguity list
- Governance decision packet
02 · topology
Small specialists. Named handoffs. One accountable decision.
Each stage produces an artifact another stage can inspect. The final node is a person, not an autonomous write to an external system.

Validate and normalize the metric definition review inputs.

Produce the definition completeness audit.

lineage and grain reviewer
Produce the conflict and ambiguity list.

metric governance reviewer
Challenge the metric definition review result and prepare an approval packet.

03 · authority
Grant the run only what this case needs.
Source material is read-only. Drafts land in a case-specific output path. Tools may read or propose; the human gate owns the external write.
case inputs
workspace/data/metric-definition-review/inputs/**Read only the evidence attached to this workflow instance.
case outputs
workspace/data/metric-definition-review/outputs/**Write drafts and evidence artifacts without modifying source records.
approved tools
data:metric-definition-review:read-or-proposeInvoke only tools explicitly granted for this run; external writes remain gated.
04 · implementation
A private, bounded starting manifest.
The blueprint starts private, caps its DAG, disables replanning, and exposes no public endpoint. Add only the tools and data adapters this workflow has approved.

Evidence traceability
Every material conclusion cites an input artifact or a scoped tool result from this run.
- 02
The definition specifies owner, purpose, formula, grain, population, filters, time behavior, exclusions, and source lineage.

- 03
Approval boundary
The run stops at a proposal and records the human decision before any external side effect.
failure containment
Stop small. Preserve the evidence.
Business meaning, source-of-record, denominator, grain, or historical treatment is disputed.
Containment: Return a partial result with unresolved items; do not broaden scope or perform an external write.
Operator: Attach the missing evidence, narrow the brief, or explicitly approve a new scoped run.
A required input or tool grant is unavailable.
Containment: Stop the affected branch and preserve completed artifacts in the case output workspace.
Operator: Grant only the missing resource or continue with that branch marked out of scope.
06 · proof
Sign the run facts. Keep money in the billing ledger.
Current platform receipts sign caller identity or classification, skill, bounded input evidence, verified grant IDs when present, outcome or result preview, and timing. Optional file, tool, artifact, handoff, evaluation, and review fields require separate instrumentation and are not populated by default. Price, fees, payouts, and later human approvals remain separate platform records.
The example uses only fields populated by the current platform sealing paths. It is illustrative, not a record of a real customer run.
