rpi-workflow

rpi-workflow is a skill for Claude Code, Codex from shubham0704/claude-skills. It costs 62 tokens per session (909 once invoked), scanned A, original, MIT.

A structured Research-Plan-Implement workflow for complex engineering tasks, with a Codex review step. It stores research, plans, implementation reports, and optional validation documents in a project's docs folder.

In plain words
What is it for?
Use it to research a codebase, create an implementation plan, request an architectural review, and document the completed work and validation.
Why use it?
It separates investigation from design and coding, making decisions and review feedback easier to track.

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

rpi-workflow 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 10d 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.

RPI Workflow: Research -> Plan -> Implement

A structured workflow for complex engineering tasks with Codex architectural review.

When to Invoke

  • User says /rpi or "start RPI"
  • User wants structured research before implementation
  • User wants Codex to review a plan
  • User needs to create research docs or implementation plans

File Structure

All artifacts go in docs/ at the project root:

docs/
├── research/
│   └── YYYY-MM-DD-topic.md        # Research findings
└── plans/
    ├── PLAN-<repo>-<task>.md      # Claude creates
    ├── FEEDBACK-<repo>-<task>.md  # Codex creates
    ├── IMPL-<repo>-<task>.md      # Claude creates after implementation
    └── VALIDATION-<repo>-<task>.md # Codex creates (optional)

Workflow Steps

Step 1: Research Phase

Launch parallel Explore agents to gather codebase understanding:

Task(subagent_type="Explore", prompt="Research how X works...")
Task(subagent_type="Explore", prompt="Research how Y connects to Z...")

Save findings to docs/research/YYYY-MM-DD-topic.md using the research template. For the template structure, see TEMPLATES.md.

Step 2: Plan Phase

Create docs/plans/PLAN-<repo>-<task>.md with:

  • Goal (1-2 sentences)
  • Key Files (path:line references)
  • Problem (what's broken/missing)
  • Proposed Solution (phased, with file-level changes)
  • Success Criteria (checkboxes)
  • Risks (numbered)
  • Questions for Review (for Codex)

Step 3: Codex Review

Run from the project root:

codex exec --skip-git-repo-check "Read docs/plans/PLAN-<repo>-<task>.md and provide architectural feedback. Review the proposed solution, identify risks, suggest improvements. Write your feedback to docs/plans/FEEDBACK-<repo>-<task>.md"

Notes:

  • Always use --skip-git-repo-check for non-git repos
  • No --quiet flag exists
  • Codex writes feedback autonomously to the FEEDBACK file

Step 4: Read & Incorporate Feedback

Read docs/plans/FEEDBACK-<repo>-<task>.md and present key findings to the user:

  • Executive assessment
  • Missing edge cases
  • Better abstractions suggested
  • Risks not identified
  • Phase reordering suggestions
  • Actionable recommendations

What ships with it

2 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

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.
