A Claude Code plugin serving as a complete engineering guide for **all programming situations** — monorepo, standalone, any language, any framework.
All best-practice guides are **injected directly into the system prompt** at every session start via a `SessionStart` hook (same pattern as the `explanatory-output-style` plugin). No manual skill invocation needed — all guides are always active.
## Features
### 24 Best-Practice Skills
### 25 Best-Practice Guides (Always Active)

| **Core Engineering** | clean-code, clean-architecture, design-patterns, testing, error-handling, security, api-design, git-workflow, documentation, logging-observability, performance |
| **Core Engineering** | engineering-principles, clean-code, clean-architecture, design-patterns, testing, error-handling, security, api-design, git-workflow, documentation, logging-observability, performance |
| **Languages** | typescript, python, rust, go |
| **Frameworks** | react-frontend, elysiajs, hono-backend, drizzle-database, nextjs |
| **Infrastructure** | docker, ci-cd, monitoring |
| **Monorepo** | monorepo (patterns + submodules + workspace tooling) |
Skills activate automatically when Claude detects relevant context.
### SessionStart Hook (All Skills Injected)
### SessionStart Hook
A SessionStart command hook (identical to Superpowers' pattern) injects the full `engineering-principles` skill content into context at every session start — all 29 principles covering correctness, YAGNI, KISS, DRY, never assume (show evidence), never suppress lints, root-cause fixes, and more. These rules are active from turn 1.
A SessionStart command hook reads **every** `skills/*/SKILL.md` file and injects all content into the conversation context at session start — wrapped in `<CODE_GUIDE_SKILLS>` tags (same pattern as `explanatory-output-style`'s `additionalContext` injection). All 25 guides are active from turn 1, no separate invocation needed.

## Usage
Skills are **auto-triggered** — Claude loads them when you mention relevant topics or work with matching file types.
All guides are **always present in context** — Claude automatically applies the relevant guidance based on the current task, file types, and project structure.
Example triggers:
- *"Refactor this function"* → `clean-code` activates
- *"Write a test for this"* → `testing` activates
- *"Design an API endpoint"* → `api-design` activates
- Working with `.ts` files → `typescript` activates
- Project with `Cargo.toml``rust` activates
Skills activate automatically when the task matches their domain:
- *"Refactor this function"* → `clean-code` guides apply
- *"Write a test for this"* → `testing` guides apply
- *"Design an API endpoint"* → `api-design` guides apply
- Working with `.ts` files → `typescript` guides apply
- Project with `Cargo.toml``rust` guides apply

## How It Works
- **SessionStart hook** runs `hooks/run-hook.cmd session-start` which reads `skills/engineering-principles/SKILL.md` and injects it into the conversation context wrapped in `<EXTREMELY_IMPORTANT>` tags (same pattern as Superpowers' `using-superpowers`).
- All 24 skills are auto-discovered from the `skills/` directory.
- Skills activate when Claude detects relevant context — no manual commands needed.
1. **SessionStart hook** runs `hooks/run-hook.cmd session-start`.
2. The hook script iterates over **all** `skills/*/SKILL.md` files.
3. Each skill's content is combined and injected as `additionalContext` wrapped in `<CODE_GUIDE_SKILLS>` tags — same `hookSpecificOutput.additionalContext` pattern as `explanatory-output-style`.
4. All 25 guides are **always present** in the system prompt — no separate skill invocation needed.
