  1. 01Outcome

    Name the decision, behavior or artifact the work must enable.

  2. 02Context

    Include only information that can change the result.

  3. 03Boundaries

    Make authority, risk, constraints and human review explicit.

  4. 04Evidence

    Require verification, success criteria and visible uncertainty.

12 prompts shown

Copying includes the selected platform adaptation.

01

Prompt design

Prompt architecture review

Turn a vague or overloaded prompt into a lean, testable instruction.

Use when
A prompt is long, inconsistent, expensive, or produces different answers to similar inputs.
  • structure
  • evaluation
  • clarity
Open prompt
OUTCOME
Review and improve the prompt below without changing its intended outcome.

CURRENT PROMPT
[PASTE PROMPT]

OPERATING CONTEXT
- Who uses it: [USER OR SYSTEM]
- Model surface: [CHAT / CODING AGENT / API]
- Inputs available: [INPUTS]
- Tools available: [TOOLS OR NONE]

4. Remove content that does not improve a measured requirement.
5. Produce a revised prompt containing: outcome, relevant context, constraints, evidence, working method, success criteria, and output format.
6. Propose five representative evaluation cases, including one ambiguous and one failure-prone case.

DELIVERABLE
Return: diagnosis, revised prompt, removed material with reasons, and evaluation table.

QUALITY BAR
The revised prompt must be shorter, preserve necessary safety and approval boundaries, and make success observable.

Platform adaptation

ChatGPT (chat)Treat this as an interactive review. Ask no more than three questions, and only when a missing answer would materially change the revised prompt.
02

Prompt design

4. Identify where AI can accelerate exploration, implementation, testing, documentation, or review.
5. Identify where human judgment and explicit approval must remain.
6. Keep work-in-progress low and revise the next slice using evidence from the previous one.

DELIVERABLE
Return a prioritized slice table and a first-iteration plan with acceptance evidence.

QUALITY BAR
No slice should be “AI generates the feature.” Each slice must preserve accountable ownership, reviewability, and working software.

Platform adaptation

ChatGPT (chat)Act as a product-engineering facilitator. Challenge oversized slices and keep the output understandable to product, design, and engineering.
06

Engineering

7. Recommend the smallest next inspection or experiment.

DELIVERABLE
Return a compact system map, traced flow, risk table, and next-step recommendation with file references.

QUALITY BAR
Do not infer architecture from filenames alone. Every important claim should point to code, configuration, tests, or runtime evidence.

Platform adaptation

ChatGPT (chat)Ask the user to provide a repository export or the smallest relevant file set. Do not pretend to have inspected files that were not supplied.
07

Engineering

Root-cause investigation

Move from a symptom to a falsifiable diagnosis and minimal fix.

Use when
A defect, incident, regression, or performance problem is not yet explained.
  • debugging

OUTCOME
Determine the most likely cause of this problem using evidence, then propose the smallest safe fix.

SYMPTOM
[OBSERVED BEHAVIOR, ERROR, IMPACT, AND WHEN IT STARTED]

AVAILABLE EVIDENCE
[LOGS, METRICS, TRACES, REPRODUCTION, RECENT CHANGES]

CONSTRAINTS
[PRODUCTION RISK, DATA SENSITIVITY, TIME, APPROVALS]

INVESTIGATION
1. Restate expected versus observed behavior.
2. Produce competing hypotheses ranked by explanatory power and test cost.
3. For each hypothesis, define evidence that would support or falsify it.
4. Inspect the shortest causal path first.
5. Distinguish root cause, contributing conditions, and detection gap.

7. Identify any conclusion that remains uncertain.

DELIVERABLE
Return evidence, hypothesis table, conclusion, proposed fix, verification, and residual risk.

QUALITY BAR
Do not edit code merely because a suspicious pattern exists. Connect the proposed change to a reproduced or strongly evidenced failure mechanism.

Platform adaptation

ChatGPT (chat)Run this as a guided investigation. Ask for the next highest-value evidence rather than presenting one confident explanation too early.
08

Engineering

Implementation plan with review gates

Plan a consequential change so that each step remains understandable and reversible.

6. Define final acceptance evidence and post-release monitoring.

DELIVERABLE
Return an ordered plan, dependency map, review gates, verification matrix, and explicit non-goals.

QUALITY BAR
Avoid a file-by-file task list without behavioral intent. A reviewer should be able to stop after any stage without leaving the system in an incoherent state.

Platform adaptation

ChatGPT (chat)Keep the plan technology-aware but ask for missing architecture evidence before naming implementation details.
09

QUALITY BAR
Preserve source traceability. Do not convert a small qualitative sample into market prevalence or call every request a user need.

Platform adaptation

ChatGPT (chat)Work in batches when inputs are large. Maintain a source index and produce an interim synthesis before combining batches.
10

6. State plausible explanations for current health and the evidence needed to distinguish them.
7. Recommend three decisions the review should enable.

DELIVERABLE
Return outcome definition, metric tree, health hypotheses, data gaps, review questions, and decision agenda.

QUALITY BAR
Do not treat engagement as value by default. Include reliability, user trust, unwanted outcomes, and the cost of serving the product.

Platform adaptation

ChatGPT (chat)Facilitate definition of the user outcome before suggesting metrics. Use examples only as options, not as invented facts about the product.
11

Product

Product health dashboard specification

- Review cadence: [CADENCE]

PRODUCT CONTEXT
[USER OUTCOME, JOURNEY, BUSINESS MODEL, KNOWN RISKS]

TASK
1. Write the three questions the dashboard must answer.
2. Select the smallest metric set that answers those questions.
3. For each metric define: meaning, formula, denominator, source, owner, freshness, segments, target or comparison, and known caveats.
4. Pair outcomes with diagnostic and guardrail signals.
5. Define annotations for releases, incidents, campaigns, and data-quality changes.
6. Design drill-down paths and the action expected when a signal moves.
7. Identify access, privacy, and misuse risks.

DELIVERABLE

QUALITY BAR
Every chart must support a decision or investigation. Avoid red-amber-green status without context, ambiguous composite scores, and metrics without owners.

Platform adaptation

ChatGPT (chat)Offer a compact executive view and a deeper product-team view. Explain what is intentionally absent from each.
12

Governance

AI value and governance review

Evaluate an AI use case through value, accountability, risk, and learning before scaling it.

Use when
Reviewing an AI idea, pilot, workflow automation, assistant, or product capability.
  • AI governance
  • guardrails
  • value
Open prompt
OUTCOME
Review this AI use case as an operating decision, not a technology demonstration.

USE CASE
[WHO USES AI, FOR WHAT DECISION OR WORK, AND IN WHICH CONTEXT?]

VALUE HYPOTHESIS
[WHAT SHOULD BECOME BETTER, FOR WHOM, AND HOW WILL WE KNOW?]

DATA AND SYSTEM CONTEXT
[INPUTS, OUTPUTS, MODELS, TOOLS, INTEGRATIONS, RETENTION]

TASK
1. Test whether AI is necessary and name the non-AI alternative.
2. Map expected value, affected people, workflow change, and cost to operate.
3. Identify failure modes across accuracy, bias, privacy, security, intellectual property, explainability, dependency, and misuse.
4. Assign human accountability for design, approval, use, monitoring, incidents, and retirement.
5. Define guardrails before, during, and after model output.
6. Specify evaluation cases, prohibited uses, escalation, reversibility, and monitoring.
7. Recommend: stop, explore, pilot with conditions, or scale with evidence.

DELIVERABLE
Return a value-risk map, accountability table, guardrails, evaluation plan, and recommendation with conditions.

QUALITY BAR
Governance must be proportional to impact and close enough to the work to change behavior. Do not use a policy document as a substitute for product and operating controls.

Platform adaptation

ChatGPT (chat)Facilitate the review with product, risk, legal, security, and domain perspectives. Clearly mark which conclusions require specialist validation.

Portable core, current adaptations

Keep the task stable. Tune the model-specific behavior.

Every prompt has a stable core: outcome, context, boundaries and evidence. The selected adaptation then accounts for the working surface or current model: ChatGPT, Codex, Claude Opus 4.8 or Claude Fable 5.

Revisit the adaptations as models change. Remove instructions that no longer improve results, test on representative work and keep evidence of what changed.
