oc-setup AGENTS.md is an instructions file for Codex, OpenCode from mercuryPark/oc-setup. It costs 999 tokens per session, scanned A, original, MIT.

Repository instructions for an OpenCode setup plugin and command-line tool written in TypeScript and Bun. They define communication rules, project structure, and the required implementation order.

In plain words
What is it for?
Use them when implementing or modifying setup, migration, preset, provider, prompt, and related OpenCode components.
Why use it?
They keep changes aligned with the project design document and its language, code, and development conventions.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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

oc-setup AGENTS.md 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 3d ago.

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 — 97 lines — stays where its author put it; the contents beside it link to each section on GitHub.

oc-setup

OpenCode 초기 환경 세팅 플러그인 + CLI (TypeScript/Bun). 설계 문서는 DESIGN.md에 있다.

Communication Rules

  • User's Question Language: Always respond in the same language as the user's question
  • Language Detection: Automatically detect the language of each user query
  • Consistency: Never switch languages mid-conversation or mid-response
  • Technical Terms: Technical terms may remain in English if no appropriate translation exists
  • Code Comments: Follow project conventions (English for code, user's language for explanations)

핵심 원칙

  • DESIGN.md가 진실의 원천이다. 구현 시 항상 DESIGN.md를 먼저 읽고 따를 것.
  • 구현 순서는 DESIGN.md 섹션 12 Phase 2를 따른다. Step 1 → 9 순서.
  • 한 번에 하나의 Step만 구현한다.

Code Standards

  • TypeScript strict mode
  • Bun 런타임
  • 에러 처리: try/catch + 의미 있는 에러 메시지, 절대 silent fail 하지 않음
  • 모든 exported 함수/타입에 JSDoc 주석
  • 외부 의존성 최소화. 표준 라이브러리로 해결 가능하면 표준 사용

Dependencies

핵심:

  • @opencode-ai/plugin — 플러그인 SDK
  • zod — 스키마 검증 (플러그인 SDK 의존)
  • commander — CLI 프레임워크

CLI 모드:

  • @inquirer/prompts — 대화형 프롬프트

선택:

  • yaml — Aider .aider.conf.yml 파싱용 (필요시만)

불필요한 의존성 추가 금지.

Testing

  • bun test 으로 전체 테스트 실행
  • test/ 디렉토리에 src/ 구조 미러링
  • test/fixtures/ 에 Claude Code, Cursor, Aider 샘플 설정 배치

Plugin Architecture

  • src/index.ts는 Plugin 타입을 export하는 async 함수
  • tool은 tool() 헬퍼로 정의. args는 zod 스키마.
  • tool의 execute 함수는 반드시 string을 반환
  • 플러그인 context: { client, project, $, directory, worktree }

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.
