Agentic Coding Tools

The first thing the wizard asks is which agentic coding tool(s) you use. Pick any combination of:

• Claude Code
• OpenAI Codex
• OpenCode
• Cline

The registry stores everything once, in Claude Code's native shape. At generation time each artifact is retargeted / translated into the layout the selected tool actually reads — so you get valid, tool-native files without maintaining three copies of anything.

What each tool gets

Artifact	Claude Code	OpenCode	OpenAI Codex	Cline
Instructions	CLAUDE.md	AGENTS.md	AGENTS.md	AGENTS.md
Skills (same SKILL.md)	.claude/skills/<n>/	reads .claude/skills natively	.agents/skills/<n>/	.clinerules/workflows/<n>.md
Subagents	.claude/agents/<n>.md	.opencode/agents/<n>.md	.codex/agents/<n>.toml	— (no per-file agents)
Config	—	opencode.json	—	—

When you select more than one tool, the instruction files share identical composed content, and skills aren't duplicated needlessly (OpenCode reads .claude/skills directly, so no extra copy is made when Claude Code is also on).

Instructions

The composed knowledge base is written to:

• CLAUDE.md when Claude Code is selected.
• AGENTS.md when Codex, OpenCode, or Cline is selected (the cross-tool standard; OpenCode also falls back to CLAUDE.md). Cline reads AGENTS.md natively, so its instructions need no extra work.

Both hold the same content and are appended to on re-runs.

Skills

SKILL.md is byte-identical across all three tools, so skills are pure file placement — no translation:

• .claude/skills/<name>/ — Claude Code (and OpenCode reads it natively).
• .opencode/skills/<name>/ — only when OpenCode is selected without Claude Code.
• .agents/skills/<name>/ — Codex.

Subagents (translated)

Subagents are genuinely translated from the Claude Code markdown source:

→ OpenCode (.opencode/agents/<name>.md)

• name is dropped (the filename is the name).
• mode: subagent is added.
• Read-only agents get permission:\n edit: deny.
• model is intentionally omitted so the agent inherits the workspace default (avoids pinning a possibly-stale model id).

---
description: "Reviews the current diff for correctness and security…"
mode: subagent
permission:
  edit: deny
---

You are a focused code reviewer. …

→ OpenAI Codex (.codex/agents/<name>.toml)

Codex uses TOML with name, description, and developer_instructions:

name = "code-reviewer"
description = "Reviews the current diff for correctness and security…"
developer_instructions = """
You are a focused code reviewer. …
"""

Stack agents convert too

Each stack ships a specialist agent (e.g. a react agent). Because retargeting runs on every copied template, those stack-bundled agents are translated to your selected tools automatically.

Adding a tool later

Re-run the CLI in an existing project and select a new tool. It backfills that tool's layout for everything already installed — instructions file, opencode.json, standalone and stack-bundled agents, and skills — without touching any existing files. Choosing all your tools up front gives the same result in one pass.
