Definition
Shadow mode evaluation runs a candidate agent alongside an existing workflow and records what it would propose. The active workflow remains responsible for customer-visible results. For an agent, shadowing must isolate tools as well as responses: suppressing chat output is insufficient if the candidate can still create orders, send messages, or change inventory.
Why It Matters
- Offline cases may omit the incomplete data and tool failures that occur in real operations. Copied live requests can reveal these conditions.
- A candidate can agree with current decisions and still be too slow, expensive, or dependent on missing evidence for deployment.
- A Commerce Intelligence OS needs evidence about proposed actions and execution constraints before granting a candidate operational authority.
How It Works
- Define eligible traffic, the baseline, evaluation duration, and review criteria. Mirror only the input data needed for the evaluation.
- Remove write credentials and route action tools to isolated stubs or dry-run services. Check nested workflows so a simulated action cannot invoke a real downstream write.
- Log baseline and candidate proposals with evidence, latency, tool errors, and cost. Review disagreements by business severity rather than treating baseline agreement as proof of correctness.
- Use shadow findings to decide whether to revise the candidate or proceed to a separately controlled live test. Shadow results alone cannot establish incremental revenue or real customer response.
Ecommerce Example
Context: Illustrative example: a candidate support agent proposes replacement orders alongside the current service workflow.
Recommended move: Record the proposed SKU, eligibility evidence, and intended action in an isolated evaluation log. Let only the active workflow issue the actual replacement.
Why it matters: Review incorrect eligibility, missing evidence, and slow responses before enabling execution. No duplicate replacement should arise from the shadow path.
iKawn Framework
Mirror
Use the iKawn framework to provide bounded live context to an isolated candidate.
Contain
Keep commercial writes outside the shadow agent tool permissions.
Review
Connect proposed actions to evidence and operator-assessed disagreement severity.
Advance
Require separate evidence and authorization for any live rollout.
Concise Summary
Shadow mode tests proposals against real input conditions while the existing workflow remains active. It requires side-effect isolation and cannot substitute for measuring actual customer outcomes.
