01 · the contract
Start from a bounded job, not a blank chat box.
trigger
A customer story has internal and customer permission to enter drafting.
owner
marketing owner
agent stops at
Internal owners and the customer approve every attributed quote, metric, and publication use.
KPI · decrease
customer story approval cycle (days). Measure evidence-complete draft to final customer approval.
outputs
Artifacts the run must produce
- Evidence-linked story draft
- Quote and metric approval table
- Missing proof 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 customer story draft inputs.
- 02
evidence storyteller
Produce the evidence-linked story draft.
- 03
claim verifier
Produce the quote and metric approval table.
- 04
customer marketing reviewer
Challenge the customer story draft 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/marketing/customer-story-draft/inputs/**Read only the evidence attached to this workflow instance.
case outputs
workspace/marketing/customer-story-draft/outputs/**Write drafts and evidence artifacts without modifying source records.
approved tools
marketing:customer-story-draft: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.

- 01
Evidence traceability
Every material conclusion cites an input artifact or a scoped tool result from this run.
- 02
The narrative does not claim causation beyond the approved evidence and keeps all metrics scoped and dated.

- 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.
A headline result lacks a stable baseline, approved metric, or customer permission.
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.
