Instructions file for Claude CodeCodexOpenCode

Written for Claude Code and Codex and OpenCode: Claude Code plugin machinery, but also the file is AGENTS.md. Also seen: mentions Claude Code.

This is BitYoungjae/marketplace's own configuration. It tells Claude Code, Codex and OpenCode how to work on marketplace itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything marketplace configures →

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

marketplace 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 8d 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.

Repository Guidelines

Project Structure & Module Organization

  • plugins/ contains publishable Claude Code plugins (dokhak, gitkkal, nvim-doctor, obsidian-blocks, omarchy).
  • Each plugin keeps metadata in .claude-plugin/plugin.json, plus capability folders such as commands/, skills/, agents/, and optional contexts/.
  • contexts/ stores shared reference documents (for example contexts/cc/ synced Claude Code docs).
  • scripts/ contains maintenance utilities (currently scripts/cc-docs-sync.sh).
  • .github/PULL_REQUEST_TEMPLATE.md defines PR expectations.

Build, Test, and Development Commands

  • No compile/build step is required; this repository is Markdown/JSON-first.
  • Add marketplace and install a plugin locally:
    /plugin marketplace add bityoungjae/marketplace
    /plugin install gitkkal@bityoungjae-marketplace
    
  • Sync Claude Code docs:
    ./scripts/cc-docs-sync.sh --dry-run
    ./scripts/cc-docs-sync.sh --include-prompt-engineering --verbose
    
    Use --dry-run before writing files.

Coding Style & Naming Conventions

  • Use Markdown for docs and command/skill definitions; keep sections short and task-oriented.
  • Use 2-space indentation in JSON files (see plugins/*/.claude-plugin/plugin.json).
  • Use kebab-case for plugin and skill directories (for example plugins/obsidian-blocks/skills/mermaid-diagramming/).
  • Command files should map directly to slash commands (for example commands/diagnose.md -> /nvim-doctor:diagnose).
  • If English and Korean READMEs both exist, update both when behavior changes.

Testing Guidelines

  • There is no centralized automated test suite yet.
  • For each change, run focused manual validation:
    1. Verify referenced files in updated plugin.json exist.
    2. Exercise changed commands/skills in Claude Code.
    3. If docs sync changed, run ./scripts/cc-docs-sync.sh --dry-run to confirm target diffs.

Commit & Pull Request Guidelines

  • Preferred commit format follows Conventional Commits with optional scope:
    • feat(dokhak): add model-aware tool selection
    • docs(obsidian-blocks): update mermaid note
  • Emoji-style subjects appear in history, but keep messages clear, scoped, and actionable.
  • Open PRs using .github/PULL_REQUEST_TEMPLATE.md: complete Summary, Changes, Test Plan, and checklist items for style/docs updates.
  • Link related issues/PRs in the title or body (for example (#5)).

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.
