01
Familiar visible outcome
A small evaluation set, explicit rubric, failure log, and evidence-backed decision to adopt, revise, or stop the workflow.
02
Who it is for
Anyone deciding whether a prompt, skill, agent, or automation is dependable enough for recurring use.
03
Inputs
- The promised outcome
- Representative normal cases
- At least one edge and one failure case
- A baseline manual method
- A scoring rubric
- Human review time and correction cost
04
Steps
Define the claim
Write what 'works' means as an observable artifact or decision. Separate technical execution, output quality, and business usefulness.
Build the evaluation set
Use a small representative set containing normal, incomplete, ambiguous, adversarial, and out-of-scope cases. Keep private production data out unless explicitly authorized.
Create the rubric before running
Score factual support, completeness, instruction following, safety, usability, and correction effort. Weight the dominant failure mode most heavily.
Run the baseline and workflow
Compare against the current manual or simpler method. Record inputs, versions, outputs, latency, cost, and human interventions.
Inspect failures
Classify each failure by cause, detectability, consequence, and recovery. A workflow that fails visibly may be safer than one that produces plausible errors.
Make the adoption decision
Adopt only for the cases demonstrated. Specify monitoring, review gates, rerun triggers, and the evidence that would suspend the workflow.
05
Tools
- An evaluation table
- Synthetic fixtures
- A baseline artifact
- A rubric
- Run receipts or logs
06
Human approval points
- Workflow owner approves the success claim and rubric
- Data owner approves evaluation inputs
- Qualified reviewer scores high-stakes outputs
- Process owner approves adoption scope and monitoring
07
Failure behavior
- If the success claim cannot be observed, rewrite it before testing
- If a failure is consequential and hard to detect, keep a human gate or reject the workflow
- If the workflow only beats a straw-man baseline, run a realistic comparison
- If model, prompt, skill, or tool version changes materially, rerun the relevant evaluation
08
Verification checklist
- The evaluation covers normal, edge, failure, and out-of-scope cases
- The rubric existed before outputs were judged
- A realistic baseline is included
- Human correction time and severity are recorded
- Failures have causes and recovery actions, not just scores
- The adoption claim is limited to demonstrated cases
- A suspension or reversal condition is defined
09
Copyable starter prompt
Design an honest evaluation for this AI workflow. Workflow: [prompt, skill, agent, or automation] Promised outcome: [observable result] Current baseline: [manual or simpler method] Users and stakes: [who relies on it and cost of error] Available test cases: [describe] Dominant failure mode: [what matters most] Create: a precise success claim, representative synthetic evaluation set, weighted rubric, baseline comparison, run log fields, failure taxonomy, human-effort measurement, adoption thresholds, monitoring plan, and suspension condition. Include normal, incomplete, ambiguous, adversarial, and out-of-scope cases. Do not use a successful run status or model confidence as proof.

Worked synthetic example
Synthetic example
Scenario
A meeting-summary prompt is proposed for weekly leadership meetings.
Input
Five synthetic transcripts: clear decisions, no decisions, conflicting owners, sensitive sidebar, and poor transcription. Baseline is a human note-taker.
Result
The prompt passes decision extraction but invents owners in two cases and leaks the sensitive sidebar. The decision is revise, not adopt. Owner invention becomes a hard-fail criterion; privacy filtering and a human approval gate are required before retest.
