A workflow for creating OpenShell RFCs, or Requests for Comments: written proposals for architecture, APIs, processes, or changes affecting several parts of a project.

Use it to draft or update an RFC in the project’s rfc/ directory, including its scope, motivation, proposal, alternatives, and open questions.

It provides the required project template and lifecycle steps, making proposals consistent and easier for others to review.

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.

Made for: Claude Code, Codex.

Per session 67 Skills are progressive disclosure: only the name and description are preloaded; the body loads when the skill is used.

When invoked 565 The whole file, excluding the scripts and references it only reads on demand.

Origin original No closer match found in the catalogue.

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.

Model	Per session	Once invoked
Fable 5	$0.00067	$0.00565
Opus 5	$0.00034	$0.00282
Sonnet 5	$0.00013	$0.00113
Haiku 4.5	$0.00007	$0.00056

Security

Grade A, and why

create-rfc 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 yesterday.

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.

How it starts

The opening of the file, as written. The whole thing — 52 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Create RFC

Workflow

Create RFCs by following rfc/README.md and rfc/0000-template/README.md. Keep the template as the source of truth for section guidance.

Read rfc/README.md to confirm when an RFC is appropriate, how to choose the RFC number, and how the lifecycle works.
Read rfc/0000-template/README.md before drafting. Follow its section guidance, including scope, expected detail, and suggested section length.
Choose the next available NNNN from the existing rfc/NNNN-* directories unless the user provided a specific number.
Create rfc/NNNN-short-title/README.md by copying the template and replacing placeholders. Use a short hyphenated folder title.
Fill in front matter with the RFC author, state: draft, and any related links the user provided. If the author is unknown, use the requesting user's GitHub handle when available or leave the template placeholder.
Draft each section from the user's design context. Keep Summary concise, Motivation readable by anyone, Non-goals explicit, Proposal focused on what is being proposed, and Alternatives focused on credible competing approaches.
Preserve uncertainty in Open questions instead of silently deciding unknowns. If a missing decision blocks a coherent RFC, ask the user for that decision.
Check the completed RFC against the template once more before finishing.

Writing Standards

Prefer concrete design statements over placeholder language.
Link to relevant issues, prior RFCs, and architecture docs when they provide needed context.
Keep rejected or left-out designs in Alternatives, not Proposal.
Use Mermaid diagrams for architecture or data flow when a diagram would make the proposal easier to review.
Do not update architecture/ or published docs just because an RFC was drafted. Those updates belong with implementation or with an accepted RFC when the user asks for them.

Validation

Before handing the RFC back to the user:

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.

create-rfc is a skill published in the GitHub repository NVIDIA/OpenShell (8,421 stars, last pushed 2d ago), licensed Apache-2.0. It adds 67 tokens to every session and 565 once invoked, about $0.0003 per session on Opus 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 2026-08-30.
