Portable cross-language engineering guidance selected from ECC rules.

[Upstream project ↗](https://github.com/affaan-m/ECC/tree/25278e7d7b6cf6e6a4e7a6c8e10f14ff22f0eb5b/rules/common) [View repository ↗](https://github.com/affaan-m/ECC) 

### Install into your coding agents

```sh
uvx awesome-python-dev init --agents codex,claude --tools ecc-common-rules
```

Run inside the project you want to equip. This command targets Codex and Claude Code; use `--agents` to choose other supported agents. [Read the prerequisites and setup guide](https://m9rco.github.io/awesome-python-dev/getting-started/) .

Rule packs are adapted to native agent instructions. Required common and language packs are included automatically. Existing user instructions outside managed sections are preserved.

### Integration notes

Selected Markdown rules only; excludes ECC hooks, agent orchestration, and model-selection rule files. Native activation adapts language scopes and crosslinks; original sources retain MIT attribution. Named ECC reviewer/planner roles and Claude settings assumptions require the portable adaptation described in docs/ECC-MIGRATION.md.
