.codex/skills/ralplan/SKILL.md

ralplan is a skill for Codex from junghwaYang/oh-my-codex. It costs 0 tokens per session (426 once invoked), scanned A, original, MIT.

An iterative planning process that drafts a solution, has it challenged, then refines it until the plan is agreed and ready to implement.

In plain words
What is it for?
Use it to plan complex features, architecture decisions, integrations, and collaborative design work.
Why use it?
It helps uncover missing requirements, risks, unnecessary complexity, and better alternatives before coding begins.

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

ralplan 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 2mo 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

Ralplan Skill

Iterative planning with consensus building.

When to Use

  • Complex features needing multiple perspectives
  • Architecture decisions with tradeoffs
  • When initial plan might miss considerations
  • Collaborative design sessions

How It Works

Round 1: Initial Plan
    │
    ▼
Round 2: Critique & Improve
    │
    ▼
Round 3: Refine & Validate
    │
    ▼
Consensus Reached → Execute

Process

Round 1: Draft

Planner creates initial plan:
- Goals
- Approach
- Tasks
- Estimates

Round 2: Critique

Critic reviews and challenges:
- Missing considerations?
- Better alternatives?
- Risks not addressed?
- Complexity concerns?

Round 3: Refine

Planner incorporates feedback:
- Address critiques
- Add missing pieces
- Simplify where possible
- Finalize plan

Consensus Check

Both agents agree:
- Plan is complete
- Risks are mitigated
- Approach is sound
→ Ready for execution

Usage

ralplan: design the notification system

ralplan: architect the payment integration

ralplan this feature before implementing

Output

## Ralplan: {Feature}

### Round 1: Initial Plan
{Planner's draft}

### Round 2: Critique
{Critic's feedback}
- ⚠️ {concern 1}
- ⚠️ {concern 2}
- 💡 {suggestion}

### Round 3: Refined Plan
{Improved plan addressing feedback}

### Consensus
✅ Both agents agree on final plan

### Final Plan
{Ready for execution}

Benefits

  1. Multiple perspectives - Catches blind spots
  2. Stress-tested - Plan survives criticism
  3. Better estimates - More realistic after critique
  4. Documented reasoning - Know why decisions were made

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.
