# production-grade A skill that makes the agent read the repo, plan before coding and ship the smallest correct change. Useful for non-trivial work and refactoring. - skill · `type=skill` · Claude Code, Codex, Cursor, GitHub Copilot, Gemini CLI, OpenCode · 815 installs · ★ 17 - Author: a-tokyo - License: MIT · policy=mirror · the beginning of the file is at the end of this page - Source: https://github.com/a-tokyo/agent-skills/tree/HEAD/skills/production-grade/SKILL.md - Updated: 2026-10-24 - HTML: https://affpapa.org/en/nevibecode/skills/production-grade ## What it does The skill encodes an engineering posture for the agent: harvest the local codebase first, match its idiom, and check current framework docs instead of relying on training recall. It ships three meta-rules and sixteen operating rules, with a `references` folder covering anti-patterns, minimalism and stack eras. The rules cover planning, database schema changes, security, infrastructure and public API surfaces. There is a dependency and CVE audit lane, plus guidance for hardening inherited or generated code and stripping over-engineering. A minimalism ladder runs before any code: does this need to exist, does the stdlib do it, does a native platform feature do it, does an installed dependency do it. Nothing here is tied to one language or framework. Skip it for one-line typos and config edits with no code consequence. ## Install ### Claude Code (native platform) 1. **Skills CLI (Vercel)** ```bash npx skills add a-tokyo/agent-skills --skill production-grade -a claude-code ``` 2. **Manually: put the files in place** - File: `~/.claude/skills/production-grade/SKILL.md` — Copy the whole skill folder; for one project use .claude/skills/production-grade/ ### Codex 1. **Skills CLI (Vercel)** ```bash npx skills add a-tokyo/agent-skills --skill production-grade -a codex ``` 2. **Manually: put the files in place** - File: `.agents/skills/production-grade/SKILL.md` — For all projects use ~/.agents/skills/ ### Cursor 1. **Skills CLI (Vercel)** ```bash npx skills add a-tokyo/agent-skills --skill production-grade -a cursor ``` 2. **Manually: put the files in place** - File: `.cursor/skills/production-grade/SKILL.md` — Cursor also reads .agents/skills/ and .claude/skills/ ### GitHub Copilot 1. **GitHub CLI** ```bash gh skill install a-tokyo/agent-skills production-grade ``` 2. **Manually: put the files in place** - File: `.github/skills/production-grade/SKILL.md` ### Gemini CLI 1. **Skills CLI (Vercel)** ```bash npx skills add a-tokyo/agent-skills --skill production-grade -a gemini-cli ``` 2. **Platform CLI** ```bash gemini skills install https://github.com/a-tokyo/agent-skills --path skills/production-grade ``` ### Windsurf (Devin Desktop) **Manually: put the files in place** - File: `.devin/skills/production-grade/SKILL.md` — The legacy .windsurf/skills/ path still works ### OpenCode **Skills CLI (Vercel)** ```bash npx skills add a-tokyo/agent-skills --skill production-grade -a opencode ``` ### Claude.ai **Claude.ai** - Zip the folder and upload it in Settings → Capabilities → Skills Where a file is given instead of a command, copy the files from the source to that path: https://github.com/a-tokyo/agent-skills/tree/HEAD/skills/production-grade/SKILL.md ## When to use it - plan a non-trivial change before writing any code - run root-cause analysis across several subsystems - audit dependencies and migrations in inherited code - strip over-engineering and dead code under YAGNI - keep schema, queries and indexes in one artefact ## Example prompts - plan the payments refactor, plan first then code - check this service for over-engineering and tell me what we can delete - do an RCA on why the worker crashes after deploy ## Source text · SKILL.md · MIT Below is the content of a third-party file.

BEGIN THIRD-PARTY FILE 1aca30ff1ccaa86f ```text --- name: production-grade version: 0.0.5 description: "Principle-engineering posture for production-grade code: reads the repo first, plans before code, matches conventions, pulls latest docs over training recall, and ships the simplest correct change that holds the bar — proper algorithms and data structures, idempotent writes, schema+queries+indexes as one artefact, typed errors, tests in the same diff. Substrate-agnostic; defers to peer skills on their lanes. Use for non-trivial planning, design, implementation, review, or refactoring; RCA and debugging; performance and optimization work; changes touching a database schema, security, infrastructure, or a public API; hardening inherited, vibe-coded, or LLM-generated code (dependency/CVE and migration audits); and over-engineering cleanup (\"simplest solution,\" \"YAGNI,\" \"what can we delete\")." license: MIT --- # production-grade Principle-engineering posture as a skill. Reads the local codebase first, matches its idiom, ships changes that earn every character. Substrate-agnostic — the principle is portable; the stack is a fit decision. ## When to use Load this skill for non-trivial engineering work in any language, framework, or substrate: planning ("plan of plans," "do it the right way") and implementation; changes touching a database schema, a security-impacting subsystem, infrastructure, or a public API surface; RCA, coordinated multi-subsystem drops, and rename campaigns; reviewing or refactoring; raising a vibe-coded codebase toward the principle bar; hardening inherited or generated code — dependency / CVE, security, and migration audits (R16); and minimalism passes — *"be lazy," "simplest / minimal solution," "YAGNI," "is this over-engineered," "what can we delete"* (R2, `references/11-minimalism-audit.md`). Skip for one-line typos, comma-only doc fixes, and config edits with no code consequence. ## Meta-rules Three meta-rules modulate every operating rule. Read them as the lens; read the R-rules as the directive set. ### M1 — Principle over substrate, concept over instance The principle is portable; the substrate is not the principle. The agent names slots, not brands — *"an SMS provider"* before *"Twilio,"* *"an observability platform"* before *"Datadog."* It leads with the principle (EXPLAIN-first, runtime-coherent, never-N+1) and lets the substrate be a fit decision. Era is per-file inside long-lived repos — new code follows the modern era, existing code follows its own, mixing eras inside a single diff is the anti-pattern. See `references/01-stack-eras.md` and `references/04-toolchain.md`. ### M2 — Context first, continuously learning ``` END THIRD-PARTY FILE 1aca30ff1ccaa86f The third-party file has ended.
