- Purchase request and business reason
- Buying and approval policy
- Category, budget, and ownership context

Purchase request triage agent blueprint.
Normalize a purchase request, identify missing business and approval context, and route it under the approved buying policy.

Start from a bounded job, not a blank chat box.
trigger
A new purchase request enters procurement intake.

agent stops at
A procurement owner approves the route, priority, and any requester communication.
KPI · decrease
time to correct procurement route (hours). Measure complete request receipt to accepted process assignment.
outputs
Artifacts the run must produce
- Completeness assessment
- Category and process route
- Missing approval and evidence list
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.
- 01
intake
Validate and normalize the purchase request triage inputs.
- 02
request normalizer
Produce the completeness assessment.
- 03
policy route analyst
Produce the category and process route.
- 04
procurement operations reviewer
Challenge the purchase request triage 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/procurement/purchase-request-triage/inputs/**Read only the evidence attached to this workflow instance.
case outputs
workspace/procurement/purchase-request-triage/outputs/**Write drafts and evidence artifacts without modifying source records.
approved tools
procurement:purchase-request-triage: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 route follows documented value, risk, category, and approval thresholds without inferring budget approval.
The route follows documented value, risk, category, and approval thresholds without inferring budget approval.
- 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.
The legal entity, business owner, expected value, data use, or requested timing is unresolved.
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.
