What is openspec-new-change?

A setup helper for OpenSpec, a system that organizes proposed software changes into structured documents. It creates a change folder and displays the template for the first document.

Use it when starting or scaffolding an OpenSpec change, or when you need to know which document comes first.

It removes the need to remember the folder structure and setup commands before planning a change. It stops before writing proposal content.

Install

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.

Any agent

npx skills add redhat-developer/rhdh-skills --skill openspec-new-change

Clone the repo

git clone --depth 1 https://github.com/redhat-developer/rhdh-skills

Made for: Claude Code, Codex.

Or install refinement, the plugin that ships this one along with the rest of its 13 skills.

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 5.1	$0.00098	$0.00787
Opus 5	$0.00049	$0.00394
Sonnet 5	$0.00020	$0.00157
Haiku 4.5	$0.00010	$0.00079

Security

Grade A, and why

openspec-new-change 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 8d 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.

How it starts

The opening of the file, as written. The whole thing — 80 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Start a new OpenSpec change

Scaffold a change directory and hand the caller the first artifact's template, then stop — drafting content is a separate turn.

Steps

Ensure the project schema is installed. Check whether openspec/config.yaml and openspec/schemas/rhdh-spec-driven/ already exist. Only if either is missing, invoke /rhdh-spec-driven-schema and run its project-install step. Then confirm with openspec schemas --json that rhdh-spec-driven is listed.
Get the change name. If the user's request already names it or describes what they want to build, derive a kebab-case name (e.g. "add user authentication" -> add-user-auth). Otherwise ask what they want to build or fix; do not proceed without knowing.
Pick the schema. Prefer rhdh-spec-driven (now on disk). Pass --schema rhdh-spec-driven, or omit --schema to take the configured default from openspec/config.yaml. If the user names another available schema from openspec schemas --json, use that instead.
Create the change directory:
```
openspec new change "<name>" [--schema <name>]
```
This scaffolds openspec/changes/<name>/ with the selected schema.
Show status:
```
openspec status --change "<name>"
```
Get the first artifact's instructions. Find the first artifact with status: "ready" in the status output (schema-dependent — proposal for rhdh-spec-driven), then:
```
openspec instructions <first-artifact-id> --change "<name>" --json
```
Read /rhdh-spec-driven-schema for what the context, rules, and template fields in that response mean before summarizing them.
Stop and wait for user direction.

Output

Summarize: change name and location, schema and its artifact sequence (proposal -> {specs, design} -> tasks for rhdh-spec-driven — specs and design are siblings that each depend only on proposal), current status (0/N artifacts complete), and the template for the first artifact. Close with: "Ready to create the first artifact? Describe what this change is about and I'll draft it, or ask me to continue."

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.
