GAP-PROMPT-008: Coding Philosophy Prompt Section

Description

Inject coding philosophy guardrails into task prompts for code-writing effects. When the orchestrator delegates code tasks to non-CC harnesses (Pi, Gemini, Codex), the delegated agent lacks CC's built-in coding philosophy rules that prevent over-engineering, speculative abstractions, and unnecessary refactoring.

Current State

CC includes detailed coding philosophy in its system prompt ("Don't add features beyond what was asked", "Don't create helpers for one-time operations", "Three similar lines is better than a premature abstraction"). When babysitter delegates to CC, these rules apply. When delegating to Pi, Gemini, or Codex, no equivalent rules exist. Process prompts and instructions:* output do not include coding philosophy.

Target State

A codingPhilosophy prompt section in packages/sdk/src/prompts/ injected into task prompts for code-writing effects. Content adapted from CC's "Doing Tasks" section. Injected via the runtime stratum when task kind indicates code modification. Configurable per process definition (can override or extend).

Dependencies

• GAP-PROMPT-001 -- strata model for section placement

Recommendation

Phase 2 implementation. Small effort -- extract CC's coding philosophy phrasing, adapt for babysitter context, add as a prompt section. High impact for non-CC harness quality.
