Pattern Proposal: Git Delta to Prompt Facts

Summary

Steering models translate raw repository deltas into structured prompt facts and architectural deltas.

Candidate Pattern

• ID: git-delta-prompt-facts
• Classification: intelligence
• Maturity: emerging
• Type: emerging

Observed Signals

No specific signals listed.

Evidence

Supporting Evidence

• src/cas_runner/steering/models.py (RawGitDelta, GitChangeType, PromptFact, ArchitecturalDelta) - Model names indicate a data path from repository delta to structured steering fact.

Scope Assessment

• Evidence Strength: low
• Confidence: low
• Applies to: ideas-to-life-cas

Rationale

• Intent: Provide LLM steering based on concrete repository evidence rather than unstructured assumptions.
• Context: Present in the steering model layer, with RawGitDelta, GitChangeType, PromptFact, and ArchitecturalDelta definitions.
• Force: Prompts need relevant, bounded context.
• Force: Architectural reasoning should be traceable to code changes.
• Force: Raw diffs are noisy and need transformation before use.
