openspec-new-changeStart a new OpenSpec change using the experimental artifact workflow.
Openspec New Change is an agent skill from elastic/terraform-provider-elasticstack, published by the product's own GitHub organization. Start a new OpenSpec change using the experimental artifact workflow. Use when the user wants to create a new feature, fix, or modification with a structured step-by-step approach.
Its SKILL.md is about 940 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts. Compatibility notes: Requires openspec CLI.
The repository describes itself as: Terraform provider for Elastic Stack. The licence is MIT.
6 steps, taken from the first numbered list in SKILL.md.
Read from SKILL.md and the folder at commit ab9d355. It shows what the files ask for, not the result of running them.
Pre-approves these tools, so the agent can use them without asking each time:
Bash(openspec:*)From allowed-tools in the SKILL.md frontmatter.
No scripts in the folder and no shell commands in SKILL.md (its code samples are bash).
From the folder's file list and the shell code blocks in SKILL.md.
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Requires openspec CLI.
From compatibility in the SKILL.md frontmatter.
Openspec New Change loads about 943 tokens when it runs. Until then it costs about 50 tokens; SKILL.md has 476 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

.claude/skills/openspec-new-change/SKILL.md (or your agent's skills folder).Start a new change using the experimental artifact-driven approach.
Store selection: If the user names a store (a store is a standalone OpenSpec repo registered on this machine) or the work lives in one, run openspec store list --json to discover registered store ids, then pass --store <id> on the commands that read or write specs and changes (new change, status, instructions, list, show, validate, archive, doctor, context, schemas, view). Once selected, treat --store <id> as sticky for the rest of the workflow. Every unscoped example of those commands below is shorthand: before running it, append the flag. For example, run openspec status --change "<name>" --json --store "<id>", not the unscoped form shown below. Other commands do not take the flag. Hints printed by commands already carry the flag; keep it on follow-ups. Without a store, commands act on the nearest local openspec/ root.
Input: The user's request should include a change name (kebab-case) OR a description of what they want to build.
Steps
If no clear input provided, ask what they want to build
Ask the user (open-ended, no preset options):
"What change do you want to work on? Describe what you want to build or fix."
From their description, derive a kebab-case name (e.g., "add user authentication" → add-user-auth).
IMPORTANT: Do NOT proceed without understanding what the user wants to build.
Determine the workflow schema
Use the default schema (omit --schema) unless the user explicitly requests a different workflow.
Use a different schema only if the user mentions:
--schema <name>openspec schemas --json and let them chooseOtherwise: Omit --schema to use the default.
Create the change directory
openspec new change "<name>"Add --schema <name> only if the user requested a specific workflow.
This creates a scaffolded change in the planning home resolved by the CLI.
Show the artifact status
openspec status --change "<name>" --jsonUse the returned planningHome, changeRoot, artifactPaths, and nextSteps instead of assuming repo-local paths.
Get instructions for the first artifact
The first artifact depends on the schema (e.g., proposal for spec-driven).
Check the status output to find the first artifact with status "ready".
openspec instructions <first-artifact-id> --change "<name>"This outputs the template and context for creating the first artifact.
STOP and wait for user direction

Openspec New Change fits situations like: the user wants to create a new feature; modification with a structured step-by-step approach.
Run `npx skills add elastic/terraform-provider-elasticstack --skill openspec-new-change -a claude-code`. Or copy the skill folder (.agents/skills/openspec-new-change in elastic/terraform-provider-elasticstack) into .claude/skills/openspec-new-change in your project. Claude Code loads it when a task matches its description.
Run `npx skills add elastic/terraform-provider-elasticstack --skill openspec-new-change -a codex`. Or copy the skill folder (.agents/skills/openspec-new-change in elastic/terraform-provider-elasticstack) into .agents/skills/openspec-new-change in your project. Codex loads it when a task matches its description.
Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add elastic/terraform-provider-elasticstack --skill openspec-new-change -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/openspec-new-change, .gemini/skills/openspec-new-change, .github/skills/openspec-new-change and .opencode/skills/openspec-new-change in your project.
SKILL.md names no scripts, command-line tools or credentials: Openspec New Change is instructions for the agent only. Its frontmatter pre-approves these tools: Bash(openspec:*). Compatibility (from SKILL.md): Requires openspec CLI..
SKILL.md contains no URLs. Any network use would come from the scripts or tools the agent runs. This is read from the text; nothing was executed.
Our automated static check of SKILL.md found no risky patterns, such as piping downloads into a shell, reading credential files or hidden Unicode. It is not a guarantee. Review the folder before installing.
Openspec New Change is published under the MIT licence (declared in SKILL.md). It allows redistribution, so the full SKILL.md is shown on this page.
About 943 tokens (SKILL.md is roughly 3.8k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full.
