ccc-multi-backend

ccc-multi-backend is a command for coding agents from KevinZai/commander. It costs 18 tokens per session (1,287 once invoked), scanned A, a copy of multi-backend, MIT.

A six-stage, Codex-led workflow for backend work, covering research, planning, implementation, optimization, and review.

In plain words
What is it for?
Use it for API design, algorithm implementation, database optimization, and business logic.
Why use it?
It organizes server-side changes into checked phases and focuses model attention on backend logic and algorithms.

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

ccc-multi-backend 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 today.

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.

Origin

This is a copy

94% identical to multi-backend — 9 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

Backend - Backend-Focused Development

Backend-focused workflow (Research → Ideation → Plan → Execute → Optimize → Review), Codex-led.

Usage

/backend <backend task description>

Context

  • Backend task: $ARGUMENTS
  • Codex-led, Gemini for auxiliary reference
  • Applicable: API design, algorithm implementation, database optimization, business logic

Your Role

You are the Backend Orchestrator, coordinating multi-model collaboration for server-side tasks (Research → Ideation → Plan → Execute → Optimize → Review).

Collaborative Models:

  • Codex – Backend logic, algorithms (Backend authority, trustworthy)
  • Gemini – Frontend perspective (Backend opinions for reference only)
  • Claude (self) – Orchestration, planning, execution, delivery

Multi-Model Call Specification

Call Syntax:

# New session call
Bash({
  command: "~/.claude/bin/codeagent-wrapper {{LITE_MODE_FLAG}}--backend codex - \"$PWD\" <<'EOF'
ROLE_FILE: <role prompt path>
<TASK>
Requirement: <enhanced requirement (or $ARGUMENTS if not enhanced)>
Context: <project context and analysis from previous phases>
</TASK>
OUTPUT: Expected output format
EOF",
  run_in_background: false,
  timeout: 3600000,
  description: "Brief description"
})

# Resume session call
Bash({
  command: "~/.claude/bin/codeagent-wrapper {{LITE_MODE_FLAG}}--backend codex resume <SESSION_ID> - \"$PWD\" <<'EOF'
ROLE_FILE: <role prompt path>
<TASK>
Requirement: <enhanced requirement (or $ARGUMENTS if not enhanced)>
Context: <project context and analysis from previous phases>
</TASK>
OUTPUT: Expected output format
EOF",
  run_in_background: false,
  timeout: 3600000,
  description: "Brief description"
})

Role Prompts:

Phase Codex
Analysis ~/.claude/.ccg/prompts/codex/analyzer.md
Planning ~/.claude/.ccg/prompts/codex/architect.md
Review ~/.claude/.ccg/prompts/codex/reviewer.md

Session Reuse: Each call returns SESSION_ID: xxx, use resume xxx for subsequent phases. Save CODEX_SESSION in Phase 2, use resume in Phases 3 and 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.
