/opsx-onboard

A guided tutorial for completing a full OpenSpec change cycle in a codebase. OpenSpec is a workflow that takes a software task from planning through implementation and archiving.

In plain words
What is it for?
Use it to check whether OpenSpec is set up, choose an improvement, create planning documents, implement the task, and archive the completed change.
Why use it?
It teaches the process by having the user work through a real small task while explaining each stage.

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.

Clone the repo

Made for: Cursor.

Per session 20 Only the description is in the session, so the agent can decide to use it. The body loads when it is invoked.

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

/opsx-onboard 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 3d 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.

Origin

This is a copy

91% identical to OPSX: Onboard — 35 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

How it starts

The opening of the file, as written. The whole thing — 545 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Guide the user through their first complete OpenSpec workflow cycle. This is a teaching experience—you'll do real work in their codebase while explaining each step.


Preflight

Before starting, check if OpenSpec is initialized:

openspec status --json 2>&1 || echo "NOT_INITIALIZED"

If not initialized:

OpenSpec isn't set up in this project yet. Run openspec init first, then come back to /opsx:onboard.

Stop here if not initialized.


Phase 1: Welcome

Display:

## Welcome to OpenSpec!

I'll walk you through a complete change cycle—from idea to implementation—using a real task in your codebase. Along the way, you'll learn the workflow by doing it.

**What we'll do:**
1. Pick a small, real task in your codebase
2. Explore the problem briefly
3. Create a change (the container for our work)
4. Build the artifacts: proposal → specs → design → tasks
5. Implement the tasks
6. Archive the completed change

**Time:** ~15-20 minutes

Let's start by finding something to work on.

Phase 2: Task Selection

Codebase Analysis

Scan the codebase for small improvement opportunities. Look for:

  1. TODO/FIXME comments - Search for TODO, FIXME, HACK, XXX in code files
  2. Missing error handling - catch blocks that swallow errors, risky operations without try-catch
  3. Functions without tests - Cross-reference src/ with test directories
  4. Type issues - any types in TypeScript files (: any, as any)
  5. Debug artifacts - console.log, console.debug, debugger statements in non-debug code
  6. Missing validation - User input handlers without validation

Also check recent git activity:

git log --oneline -10 2>/dev/null || echo "No git history"

Present Suggestions

From your analysis, present 3-4 specific suggestions:

## Task Suggestions

Based on scanning your codebase, here are some good starter tasks:

**1. [Most promising task]**
   Location: `src/path/to/file.ts:42`
   Scope: ~1-2 files, ~20-30 lines
   Why it's good: [brief reason]

**2. [Second task]**
   Location: `src/another/file.ts`
   Scope: ~1 file, ~15 lines
   Why it's good: [brief reason]

**3. [Third task]**
   Location: [location]
   Scope: [estimate]
   Why it's good: [brief reason]

**4. Something else?**
   Tell me what you'd like to work on.

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.

/opsx-onboard is a command published in the GitHub repository DesignPipe/exfig (10 stars, last pushed 1mo ago), licensed MIT. It adds 20 tokens to every session and 3,101 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it A with 0 findings. It is 91% identical to OPSX: Onboard, differing in 35 lines, and is treated as a copy.
