opencode-simple: Skill for Claude Code

.opencode/skills/configure-ecc/SKILL.md

configure-ecc is a skill for Claude Code, OpenCode from zhmxiaowo/opencode-simple. It costs 38 tokens per session (3,255 once invoked), scanned D, a copy of configure-ecc, MIT.

An interactive installer for Everything Claude Code, a collection of coding-agent skills and rules. It guides you through selecting what to install and checking the resulting files.

In plain words
What is it for?
Use it to set up Everything Claude Code at user or project level, select individual skills and rules, verify paths, or optimize installed files.
Why use it?
It avoids installing the entire collection when only some parts are needed. It also helps verify or optimize an existing installation.

Skill for Claude CodeOpenCode

Written for Claude Code and OpenCode: Claude Code plugin machinery, but also installed under .opencode/. Also seen: reads .claude/ paths; mentions subagents; names the AskUserQuestion tool.

This is zhmxiaowo/opencode-simple's own configuration. It tells Claude Code and OpenCode how to work on opencode-simple 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 opencode-simple configures →

Needs its repository: it reads a path above its own folder, which exists only inside the repository. The line is grep -rn "../common/" $TARGET/rules/.

Reuse

Borrowing it

Nothing to install: this file belongs to zhmxiaowo/opencode-simple. Take a copy, put it at the same path in your own repository, and replace the rules that are about this project with yours.

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 D, and why

configure-ecc scanned grade D with 2 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 1mo 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.

.claude/, .codex/, .gemini/ hold keys, settings and other credentials a mod has no legitimate need for.

Configure Everything Claude Code (ECC)

An interactive, step-by-step installation wizard for the Everything Claude Code project. Uses AskUserQuestion to guide users through selective installation of skills and rules, then verifies correctness and offers optimization.

When to Activate

  • User says "configure ecc", "install ecc", "setup everything claude code", or similar
  • User wants to selectively install skills or rules from this project
  • User wants to verify or fix an existing ECC installation
  • User wants to optimize installed skills or rules for their project

Prerequisites

This skill must be accessible to Claude Code before activation. Two ways to bootstrap:

  1. Via Plugin: /plugin install everything-claude-code — the plugin loads this skill automatically
  2. Manual: Copy only this skill to ~/.claude/skills/configure-ecc/SKILL.md, then activate by saying "configure ecc"

Step 0: Clone ECC Repository

Before any installation, clone the latest ECC source to /tmp:

rm -rf /tmp/everything-claude-code
git clone https://github.com/affaan-m/everything-claude-code.git /tmp/everything-claude-code

Set ECC_ROOT=/tmp/everything-claude-code as the source for all subsequent copy operations.

If the clone fails (network issues, etc.), use AskUserQuestion to ask the user to provide a local path to an existing ECC clone.


Step 1: Choose Installation Level

Use AskUserQuestion to ask the user where to install:

Question: "Where should ECC components be installed?"
Options:
  - "User-level (~/.claude/)" — "Applies to all your Claude Code projects"
  - "Project-level (.claude/)" — "Applies only to the current project"
  - "Both" — "Common/shared items user-level, project-specific items project-level"

Store the choice as INSTALL_LEVEL. Set the target directory:

  • User-level: TARGET=~/.claude
  • Project-level: TARGET=.claude (relative to current project root)
  • Both: TARGET_USER=~/.claude, TARGET_PROJECT=.claude

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.
