prompt engineering automation

what i use it for

i use this for consultancy — any client prompt engineering task runs through this pipeline before delivery.

the problem

prompt engineering is skill-intensive and repetitive. analysing the task, writing the spec, drafting and validating two prompts — done well, this takes hours per client. there was no systematic way to apply senior-level prompt engineering consistently across multiple clients without sacrificing quality.

the approach

  1. 01 planner

    analyses the client task and produces a structured specification — audience, tone, constraints, success criteria, and edge cases. you review and optionally add feedback before anything moves forward.

  2. 02 system prompt generator

    builds a production-grade instruction set for the ai model from the specification. feedback from stage 1 is injected into this stage's input.

  3. 03 task prompt generator

    writes the end-user-facing prompt or prompt chain, tested against both the spec and the system prompt. the three artefacts are now complete.

  4. 04 validator

    formal quality check across all artefacts against prompt engineering principles. returns a verdict — ready to ship, or needs revision with specific notes. approved runs are saved to history.
