ccc-multi-plan

ccc-multi-plan is a command for coding agents from KevinZai/commander. It costs 15 tokens per session (2,337 once invoked), scanned C, a copy of multi-plan, MIT.

A planning workflow that gathers project context and asks two models to produce a step-by-step implementation plan without changing production code.

In plain words
What is it for?
Use it to create and save a detailed plan for a software change, with external models restricted to reading context and proposing work.
Why use it?
It separates planning from coding and validates each phase before continuing, reducing the risk of implementing an incomplete or misunderstood requirement.

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 C, and why

ccc-multi-plan scanned grade C 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 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.

Directions to print, repeat or translate the system prompt extract configuration the operator did not intend to expose.

3. Output prompt in **bold text** (MUST use actual saved file path):

Unrestricted tool accessmediumExcessive agency

A wildcard tool grant or "run any command" leaves no least-privilege boundary at all.

$ARGUMENTS


Core Protocols

  • Language Protocol: Use English when interacting with tools/models, communicate with user in their language
  • Mandatory Parallel: Codex/Gemini calls MUST use run_in_background: true (including single model calls, to avoid blocking main thread)
  • Code Sovereignty: External models have zero filesystem write access, all modifications by Claude
  • Stop-Loss Mechanism: Do not proceed to next phase until current phase output is validated
  • Planning Only: This command allows reading context and writing to .claude/plan/* plan files, but NEVER modify production code

Multi-Model Call Specification

Call Syntax (parallel: use run_in_background: true):

Bash({
  command: "~/.claude/bin/codeagent-wrapper {{LITE_MODE_FLAG}}--backend <codex|gemini> {{GEMINI_MODEL_FLAG}}- \"$PWD\" <<'EOF'
ROLE_FILE: <role prompt path>
<TASK>
Requirement: <enhanced requirement>
Context: <retrieved project context>
</TASK>
OUTPUT: Step-by-step implementation plan with pseudo-code. DO NOT modify any files.
EOF",
  run_in_background: true,
  timeout: 3600000,
  description: "Brief description"
})

Model Parameter Notes:

  • {{GEMINI_MODEL_FLAG}}: When using --backend gemini, replace with --gemini-model gemini-3-pro-preview (note trailing space); use empty string for codex

Role Prompts:

Phase Codex Gemini
Analysis ~/.claude/.ccg/prompts/codex/analyzer.md ~/.claude/.ccg/prompts/gemini/analyzer.md
Planning ~/.claude/.ccg/prompts/codex/architect.md ~/.claude/.ccg/prompts/gemini/architect.md

Session Reuse: Each call returns SESSION_ID: xxx (typically output by wrapper), MUST save for subsequent /ccg:execute use.

Wait for Background Tasks (max timeout 600000ms = 10 minutes):

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.

ccc-multi-plan is a command published in the GitHub repository KevinZai/commander (6 stars, last pushed yesterday), licensed MIT. It adds 15 tokens to every session and 2,337 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it C with 2 findings (asks the agent to reveal its instructions, unrestricted tool access). It is 95% identical to multi-plan, differing in 9 lines, and is treated as a copy.
