Description
Custom GPTs built to a professional standard
Instructions, knowledge plan, action schemas, and safety controls designed deliberately — instead of the trial-and-error most custom GPTs are assembled from.
Specification discipline from four decades of shipping
We have written the requirements behind hundreds of deployed systems. Vague specifications cause expensive rework — that lesson is engineered into how rigorously this studio pins down your instructions, knowledge and controls.
Design reliable, governable Custom GPTs
Emerald Custom GPT Prompt & Governance Studio creates implementation-ready specifications without claiming to deploy or configure an external platform.
Included workflows
- Purpose, persona, scope, instruction architecture, and response contracts
- Knowledge-source inventory, freshness, metadata, citation, and access planning
- OpenAPI-oriented action specifications and safe-failure behavior
- Privacy, security, moderation, accessibility, and sensitive-data controls
- Evaluation, monitoring, rollback, versioning, ownership, and change control
Access and limits
One-time $49 purchase; no recurring subscription. Current limits are 20 requests and 50,000 AI tokens per UTC day, with a maximum of 6 requests per minute. Service-wide safety and cost controls may pause requests.
The application uses read-only content context. It cannot create, configure, publish, or deploy a Custom GPT, API action, WordPress content, or external service. Platform features change; verify implementation steps against current provider documentation.
Replaces days of guess-and-check GPT building.
