Programming Discipline (Python · Rust · TypeScript · Go)

A four-language engineering constitution that forces reference reading before coding, then enforces strict types, TDD, and file-size discipline.

What it does

Fires whenever you touch .py, .rs, .ts/.tsx, or .go files and runs a mandatory "language gate": load the matching references/{python,rust,typescript,go} set before writing any code.
Encodes seven shared axioms: the best code is never written, the type system is your proof system, parse-don't-validate, branded primitives, exhaustive variant matching, validate only at boundaries, and test-first development.
Ships per-language canonical stacks (Pydantic v2/FastAPI, serde+thiserror/axum, Zod+Hono, gin+sqlc+pgx+slog) and mandated toolchains (uv, cargo-nextest+miri, Bun+Biome+tsc, gofumpt+golangci-lint v2+nilaway).
Enforces TDD discipline: red→green→refactor, Given/When/Then naming, a test pyramid with time budgets, minimal mocking, and a hard ban on asserting natural-language prompt text.
Runs a post-write review loop: measure pure LOC (250 = defect), then answer nine architectural self-review questions about responsibility, boundaries, escape hatches, and test coverage.

Who it's for

Developers working in any of Python, Rust, TypeScript, or Go who want consistent, type-strict AI-written code.
Tech leads who want team review standards delegated to the agent.
Teams committed to strict type safety, structured logging, and real TDD.

Example uses

"Add payment validation to this FastAPI handler" → loads the Python reference, parses input with Pydantic v2 at the boundary, writes a failing test first, then measures the file's LOC.
"Clean up logging in this Go service" → reads references/logging.md, uses log/slog at decision points only, and respects the project's existing logger.
"Refactor this Rust module with unsafe blocks" → additionally loads references/rust-ub/ and proposes a miri-backed soundness gate.

Try it now, no install

Paste this into Claude to use the skill without installing anything.

Read the instructions in this file and follow them to help me:
https://raw.githubusercontent.com/code-yeongyu/oh-my-openagent/HEAD/packages/shared-skills/skills/programming/SKILL.md

What I want: (describe your task here)

If Claude can't open the link, open it yourself and paste the contents instead.

↓ If it works for you, download the ZIP below and install it. Then it runs on its own — no pasting each time.

Install in the Claude app (no terminal)

Download the ZIP with the button below.
In Claude, open Settings → Capabilities and turn on 'Code execution and file creation'. (one time)
Go to Customize → Skills → + → 'Upload a skill' and upload the ZIP.

↓ Download ZIP

Install in Claude Code

Let Claude do it — paste this into Claude Code

Install the skill I found on AI Skill Mart.
Copy the packages/shared-skills/skills/programming folder from the GitHub repo code-yeongyu/oh-my-openagent into my ~/.claude/skills/programming/.
When it's done, tell me in one line what this skill can do.

Install with a command instead

git clone https://github.com/code-yeongyu/oh-my-openagent.git && mkdir -p ~/.claude/skills && cp -r oh-my-openagent/packages/shared-skills/skills/programming ~/.claude/skills/

⚠ This is a third-party skill. Check the source repository before installing.

Open a terminal.
Clone the repository: git clone https://github.com/code-yeongyu/oh-my-openagent.git
Create the skills directory: mkdir -p ~/.claude/skills
Copy the skill: cp -r oh-my-openagent/packages/shared-skills/skills/programming ~/.claude/skills/
Verify that the references/ and scripts/ subfolders came along — the skill depends on them.
Restart Claude Code and ask it to edit a Python/Rust/TS/Go file to confirm the skill triggers.
(Recommended) Pre-install the mandated tools: uv, bun, cargo-nextest, golangci-lint, gofumpt.
