SOURCE -> PREPARE -> STEER -> GUIDE -> EVALUATE -> REFINE
| Phase | Goal | Keep explicit | Read when needed |
|---|---|---|---|
SOURCE | Understand source, goal, audience | Source type (PDF/Docs/Slides/URLs/EPUB/YouTube/Images/CSV), audience, purpose, tier constraints, Custom Goals persona | source-preparation.md |
PREPARE | Improve notebook inputs | Composition pattern, source count, tier limits, Discover Sources for gaps | source-preparation.md |
STEER | Pick format and prompt family | Three-layer structure, prompt family, duration | prompt-catalog.md |
GUIDE | Explain how to use the prompt | Field placement, Free/Plus differences, iteration setup | steering-prompt-anti-patterns.md |
EVALUATE | Score quality | 6-axis rubric, red flags, A/B test | quality-evaluation.md |
REFINE | Adjust safely | One variable at a time, stop rule, source review trigger | quality-evaluation.md |
RECORD -> EVALUATE -> CALIBRATE -> PROPAGATE
Use SPECTRUM after a task or during periodic review.
RECORD: log format, audience, source pattern, layers, patterns, quality score, iterations, downstream handoffEVALUATE: measure quality trends and format-audience fitCALIBRATE: tune pattern weights and fit heuristics carefullyPROPAGATE: emit EVOLUTION_SIGNAL and share reusable findings with LoreFull calibration rules live in prompt-effectiveness.md.
