programming

programming is a skill for Claude Code from code-yeongyu/lazyclaudecode. It costs 261 tokens per session (9,266 once invoked), scanned A, original, MIT.

A strict set of programming instructions for Python, Rust, and TypeScript projects, with language-specific rules and modern development tools.

In plain words
What is it for?
Use it when writing or changing files in these languages, including application code, tests, and related configuration.
Why use it?
It helps keep code typed, checked, and aligned with the project's chosen tools and conventions.

Skill for Claude Code

Written for Claude Code: shipped in a Claude Code plugin.

Needs its repository: it runs a file that does not travel with it, so clone the repository first. The line is uv run scripts/python/check-no-excuse-rules.py <changed paths>.

Getting it into your agent

It runs from inside its repository, so the clone comes first — what it calls does not travel with the file alone.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

programming scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 1mo ago.

The scan reads SKILL.md. This mod also ships 2 executable files (scripts/go/check-no-excuse-rules.sh, scripts/go/new-project.py), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How it starts

The opening of the file, as written. The whole thing — 464 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Programming

You are a senior engineer who writes Python, Rust, and TypeScript with one shared discipline. Type-strict. Stack-first. Async-correct. Architecturally honest about file size.

This skill is an index. The hard per-language rules live under references/. Load the language-specific reference before writing a single line of code.

PHASE 0 — LANGUAGE GATE (RUN THIS FIRST, EVERY TIME)

DO NOT WRITE OR EDIT A SINGLE LINE OF CODE BEFORE COMPLETING THIS GATE.

  1. Identify the language from the file extension or the user's request.

  2. STOP and read the matching reference set:

    File / Language MANDATORY reading (load Read tool on every file below)
    .py, .pyi, "Python" references/python/README.md + every file under references/python/ that the README tells you to load on demand
    .rs, Cargo.toml, "Rust" references/rust/README.md + every file under references/rust/ that the README tells you to load on demand. IF the change touches unsafe, *mut, *const, MaybeUninit, FFI, unsafe impl Send/Sync, or a custom lock-free primitive: ALSO load references/rust-ub/README.md plus every file under references/rust-ub/.
    .ts, .tsx, .mts, .cts, "TypeScript" references/typescript/README.md + every file under references/typescript/ that the README tells you to load on demand
    .go, go.mod, go.sum, .golangci.yml, *.proto next to a Go module, "Go" / "Golang" references/go/README.md + every file under references/go/ that the README tells you to load on demand

  3. Only after the references are loaded, apply the shared philosophy below plus the per-language iron list from the reference.

No exceptions for "small" or "one-off" code. The whole point of the modern toolchain (uv + PEP 723, rust-script, Bun) is that disposable scripts cost nothing to write with full discipline.

Shared philosophy (all three languages)

These are not style preferences. They are the six axioms every recipe in references/ derives from.

What ships with it

60 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

programming is a skill published in the GitHub repository code-yeongyu/lazyclaudecode (18 stars, last pushed 4mo ago), licensed MIT. It adds 261 tokens to every session and 9,266 once invoked, about $0.0010 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
