OmoiOS: Skill for Claude Code

.claude/skills/oip-proposal/SKILL.md

oip-proposal is a skill for Claude Code from kivo360/OmoiOS. It costs 104 tokens per session (1,864 once invoked), scanned A, original, Apache-2.0.

A guided workflow for writing OmoiOS Improvement Proposals, documents that describe a proposed change to the OmoiOS project.

In plain words
What is it for?
Use it to create a new proposal, find the next proposal number, research relevant code, and write the result using the project’s required template.
Why use it?
It helps turn a vague idea into a proposal grounded in the project’s existing files and goals. It first asks questions about the problem and who benefits, which reduces rewrites caused by missing context.

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

oip-proposal 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 9d 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.

OIP Proposal Skill

Create OmoiOS Improvement Proposals (OIPs) through an interactive, question-driven workflow. This skill gathers context from the user, researches the codebase for accurate file references, and writes a complete proposal following the project's OIP template.

Workflow

Follow these three phases in order. Do not skip the clarification phase — proposals written without understanding the user's intent produce vague specifications that require rewrites.


Phase 1: Clarify the Proposal

Goal: Understand what the user wants to propose and why, before writing anything.

Step 1: Determine the next OIP number

Read docs/proposals/README.md and check which OIP numbers are taken:

ls docs/proposals/oip-*.md

The next number is one above the highest existing number, zero-padded to 4 digits.

Step 2: Ask clarifying questions

Use the AskUserQuestion tool to gather essential context. Ask questions based on what the user has provided so far. Not all questions will be needed for every proposal — use judgment.

Always ask:

  • What problem does this solve? (The "motivation" — should be concrete, not vague)
  • Who benefits? (Users, developers, ops, everyone?)
  • What's the proposed solution at a high level?

Ask if unclear:

  • What type of proposal is this? (Standards Track for product/code changes, Informational for guidelines, Process for workflow changes)
  • Are there constraints or non-goals? (Things this proposal deliberately does NOT do)
  • Are there alternatives you considered and rejected?
  • Does this depend on or conflict with other OIPs?
  • What's the security surface? (New endpoints, auth changes, public-facing features)
  • What infrastructure is needed? (New services, databases, external APIs)

Ask if the proposal involves frontend work:

  • Which routes or pages are affected?
  • Are new components needed, or can existing ones be reused?
  • How does this interact with the navigation/sidebar?

Ask if the proposal involves backend work:

  • Which services are affected?
  • Are database migrations needed?
  • Does this require new API endpoints?

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.
