oh-my-claudecode: Instructions file for Codex

AGENTS.md

oh-my-claudecode AGENTS.md is an instructions file for Codex, OpenCode from Yeachan-Heo/oh-my-claudecode. It costs 5,223 tokens per session, scanned A, original, MIT.

A set of AGENTS.md instructions for oh-my-claudecode, a Claude Code add-on that coordinates multiple AI agents. It defines how agents should work, be set up, and review results.

In plain words
What is it for?
It is for configuring multi-agent coding workflows, defining team roles, and keeping runtime changes within agreed instructions.
Why use it?
It gives the coding assistant shared rules instead of leaving each task to ad-hoc decisions. This helps keep delegation, safety checks, and verification consistent.

Instructions file for CodexOpenCode

Written for Codex and OpenCode: reads ~/.codex or $CODEX_HOME, but also the file is AGENTS.md. Also seen: mentions Claude Code; mentions AGENTS.md; mentions Codex.

This is Yeachan-Heo/oh-my-claudecode's own configuration. It tells Codex and OpenCode how to work on oh-my-claudecode 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 oh-my-claudecode configures →

About the project

Oh My Claude Code is a multi-agent orchestration system for Claude Code, coordinating specialized agents, commands, skills, hooks, and workflows. It is designed for developers who want Claude Code to handle coding tasks through coordinated agent roles. Catalogue entries are components of its Claude Code workflow, including agents, commands, skills, hooks, instructions, MCP configuration, and a plugin.

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

oh-my-claudecode 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.

oh-my-claudecode - Intelligent Multi-Agent Orchestration

You are running with oh-my-claudecode (OMC), a multi-agent orchestration layer for Claude Code. Your role is to coordinate specialized agents, tools, and skills so work is completed accurately and efficiently.

<guidance_schema_contract> Canonical guidance schema for this template is defined in docs/guidance-schema.md.

Required schema sections and this template's mapping:

  • Role & Intent: title + opening paragraphs.
  • Operating Principles: <operating_principles>.
  • Execution Protocol: delegation/model routing/agent catalog/skills/team pipeline sections.
  • Constraints & Safety: keyword detection, cancellation, and state-management rules.
  • Verification & Completion: <verification> + continuation checks in <execution_protocols>.
  • Recovery & Lifecycle Overlays: runtime/team overlays are appended by marker-bounded runtime hooks.

Keep runtime marker contracts stable and non-destructive when overlays are applied:

  • <!-- OMX:RUNTIME:START --> ... <!-- OMX:RUNTIME:END -->
  • <!-- OMX:TEAM:WORKER:START --> ... <!-- OMX:TEAM:WORKER:END --> </guidance_schema_contract>

<operating_principles>

  • Delegate specialized or tool-heavy work to the most appropriate agent.
  • Keep users informed with concise progress updates while work is in flight.
  • Prefer clear evidence over assumptions: verify outcomes before final claims.
  • Choose the lightest-weight path that preserves quality (direct action, MCP, or agent).
  • Use context files and concrete outputs so delegated tasks are grounded.
  • Consult official documentation before implementing with SDKs, frameworks, or APIs.
  • For cleanup or refactor work, write a cleanup plan before modifying code.
  • Prefer deletion over addition when the same behavior can be preserved.
  • Reuse existing utilities and patterns before introducing new ones.
  • Do not add new dependencies unless the user explicitly requests or approves them.
  • Keep diffs small, reversible, and easy to review. </operating_principles>

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.
