01 · the contract

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

trigger

A supplier reaches a scheduled performance or governance checkpoint.

owner

procurement owner

agent stops at

The vendor manager and business owner approve ratings, feedback, and any commercial action.

KPI · increase

vendor actions closed on time (percent). Measure approved supplier actions completed by their accountable due date.

inputs

Evidence the run may read

  • Approved service and delivery metrics
  • Issue and commitment history
  • Contractual target references
outputs

Artifacts the run must produce

  • Performance scorecard
  • Commitment and issue timeline
  • Improvement and decision questions
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.

  1. 01

    intake

    Validate and normalize the vendor performance review inputs.

  2. 02

    performance data analyst

    Produce the performance scorecard.

  3. 03

    commitment historian

    Produce the commitment and issue timeline.

  4. 04

    vendor manager reviewer

    Challenge the vendor performance review result and prepare an approval packet.

  5. 05

    procurement owner

    The vendor manager and business owner approve ratings, feedback, and any commercial action.

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.

read

case inputs

workspace/procurement/vendor-performance-review/inputs/**

Read only the evidence attached to this workflow instance.

write-output

case outputs

workspace/procurement/vendor-performance-review/outputs/**

Write drafts and evidence artifacts without modifying source records.

invoke-scoped-tool

approved tools

procurement:vendor-performance-review:read-or-propose

Invoke only tools explicitly granted for this run; external writes remain gated.

required human decision

The vendor manager and business owner approve ratings, feedback, and any commercial action.

Decision owner: procurement owner.

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.

Pass only with evidence.

  1. 01

    Evidence traceability

    Every material conclusion cites an input artifact or a scoped tool result from this run.

  2. 02

    Every rating uses a defined period, metric, target, and source and distinguishes supplier-controlled from shared causes.

    Every rating uses a defined period, metric, target, and source and distinguishes supplier-controlled from shared causes.

  3. 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.

Metrics changed definition or issue records cannot be attributed to the reviewed service and period.

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.

put the pattern to work

Start private. Scope the authority. Require the decision.

Deploy the workflow as a bounded internal agent, verify its outputs and the receipt fields actually emitted, then expand only the scopes your acceptance test proves it needs.
