opsx-onboard

opsx-onboard is a command for Codex from theoden8/webspace_app. It costs 14 tokens per session (3,093 once invoked), scanned A, a copy of OPSX: Onboard, MIT.

A guided first-time walkthrough of the complete OpenSpec workflow, from choosing a small coding task through planning, implementation, and archiving. OpenSpec is a system for organizing software changes and their requirements.

In plain words
What is it for?
Use it to learn OpenSpec while completing a small change, including creating requirements, design notes, tasks, and implementation steps.
Why use it?
It teaches the workflow by applying it to a real task in the codebase instead of only explaining it abstractly.

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 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.

Origin

This is a copy

94% identical to OPSX: Onboard — 4 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 — 524 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.
