# Mandatory Engineering Discipline & Production Etiquette

- All software architecture, implementation, refactoring, and pair-programming tasks MUST strictly adhere to the SkillBuilder suite (20 Modular Skills):

+ All software architecture, implementation, refactoring, and pair-programming tasks MUST strictly adhere to the SkillBuilder suite (22 Modular Skills):

1. **Prompt Polishing First (PPE - `/prompt-polish`)**:

- Analyze, refine, and structure incoming prompts into clear, token-efficient engineering specifications with explicit verification criteria.

2. **Continuous Conversational Learning (CLP - `/continuous-learning`)**:

- Immediately absorb user corrections and project conventions. Persist invariants to `.agents/learned_conventions.md` via `scripts/record_learning.py` and never repeat corrected mistakes.

3. **Anti-AI-Slop & Clean Craftsmanship (`/anti-slop`)**:

- Prohibit decorative badges (`shields.io`), synthetic AI marketing copy, obvious restatement comments (`// set loading to true`), and toy mock arrays.

- Prohibit neon purple gradients, glowing borders, and card-soup layouts.

- Prohibit raw emojis in interactive UI controls; use semantic Lucide SVG icons with `aria-hidden="true"`.

4. **Autonomous Deep Research & Fallback Pivots (`/research`)**:

- When any library, package, or build tool fails or is deprecated, autonomously research production alternatives, evaluate trade-offs, and implement drop-in replacements.

5. **Responsiveness QA & Sub-Agent Verification (`/qa`)**:

- Enforce 4-tier viewport matrix (Mobile 375px, Tablet 768px, Desktop 1280px, Widescreen 1920px+).

- Zero fixed-pixel containers breaking mobile layouts. Enforce minimum 44x44px touch targets and accessible focus rings.

6. **Anti-Mock / Fully Functional Mandate (`/fullstack`)**:

- Zero static mock arrays pretending to be databases. Wire up real persistence (PostgreSQL, SQLite, structured file stores), real schema validation, and end-to-end integration.

7. **Token Savings & High-Density Pairing**:

- Communicate with high information density. Omit conversational padding. Use targeted diffs and structured markdown tables.

8. **Security & Vulnerability Defense (`/security`)**:

- Never commit raw credentials. Enforce parameterization against SQL/command injection, OWASP Top 10 hardening, and secret hygiene (`.env.example`, `.env`, `.gitignore`).

9. **Standardized Containerization (`/devops`)**:

- Provide production-hardened multi-stage Dockerfiles (non-root `USER 10001`, minimal base) and `docker-compose.yml` with health checks.

10. **Network & Request Resilience (`/production-etiquette`)**:

- Enforce explicit connection/read timeouts (3s/15s), in-memory caching with invalidation, debouncing on inputs, and bounded exponential backoff with jitter on retries.

11. **Continuous Testing, QA & List-an-Error (LaE)**:

- Provide automated unit/integration tests for every feature. Catalog failures with signature, root cause, remediation, and regression test.

- 12. **Git Branching, Commit Chunking (< 1k lines), & Ready-to-Review PRs (`/git-workflow`)**:

- - Branch deliberately (`feat/`, `fix/`), decompose changes into cohesive atomic commits within the 1,000-line budget, and author complete, ready-to-merge Pull Requests.

- 13. **500-Line Source File Policy (`/world-class-engineering`)**:

+ 12. **Git Branching, Meaningful Commits (Title + Description), Push to Branch & Ready-to-Review PRs (`/git-workflow`, `/full-scale-mode`)**:

+ - Branch deliberately (`feat/`, `fix/`, `refactor/`). Enforce the 1,000-line commit budget.

+ - Mandatory multi-line commits with Conventional title AND structured description body explaining *Why*, *What*, and *Verification*. Zero lazy commits.

+ - Always push commits immediately to the remote branch (`git push origin <branch>`).

+ - Always author or update an active, ready-to-merge GitHub Pull Request with complete context, verification evidence, and rollback plans.

+ 13. **500-Line Source File Policy & Full-Scale Orchestration (`/full-scale-mode`, `/world-class-engineering`)**:

- Maintain a 500-line physical limit on all source files, verified via `scripts/check_source_line_limits.py`.
