Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00020 | $0.00339 |
| Opus 5.5 | $0.00008 | $0.00136 |
| Sonnet 5.5 | $0.00004 | $0.00068 |
| Haiku 4.5 | $0.00002 | $0.00034 |
Grade A, and why
multi-plan 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 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.
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.
What it actually says
Multi-Model Collaborative Planning
Advanced skill — Uses external model backends (Codex, Gemini) for collaborative analysis and planning.
Usage
/multi-plan <task description>
Workflow
Phase 1: Context Retrieval
- Enhance prompt using MCP tools (if available)
- Retrieve project context via semantic search
- Verify requirement completeness (score >= 7/10 to proceed)
Phase 2: Multi-Model Analysis
- Distribute requirements to multiple model backends in parallel
- Each backend analyzes from its perspective (backend logic vs frontend UX)
- Cross-validate results: identify consensus and divergence
Phase 3: Plan Synthesis
- Synthesize analyses into step-by-step implementation plan
- Include: task type, technical solution, implementation steps, key files, risks
- Save plan to
.codex/plan/<feature-name>.md
Plan Output Format
## Implementation Plan: <Task Name>
### Technical Solution
<Synthesized solution>
### Implementation Steps
1. Step 1 - Expected deliverable
2. Step 2 - Expected deliverable
### Key Files
| File | Operation | Description |
|------|-----------|-------------|
### Risks and Mitigation
| Risk | Mitigation |
|------|------------|
Key Rules
- Plan only, no implementation
- External models have zero filesystem write access
- All modifications by the orchestrator
- Present plan for user approval before execution
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.

multi-plan is a skill published in the GitHub repository Luohaothu/everything-codex (25 stars, last pushed 2mo ago), licensed MIT. It adds 20 tokens to every session and 339 once invoked, about $0.0001 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-03.
