openspec-propose

Propose a new change - create the change and generate all artifacts in one step.

I'll create a change with artifacts:

proposal.md (what & why)
design.md (how)
tasks.md (implementation steps)

When ready to implement, run /opsx:apply

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

Use the AskUserQuestion tool (open-ended, no preset options) to ask:

"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.
Create the change directory
bash
```
openspec new change "<name>"
```
This creates a scaffolded change at
```
openspec/changes/<name>/
```
with
```
.openspec.yaml
```
.
Get the artifact build order
bash
```
openspec status --change "<name>" --json
```
Parse the JSON to get:
- ```
applyRequires
```
  : array of artifact IDs needed before implementation (e.g.,
```
["tasks"]
```
  )
- ```
artifacts
```
  : list of all artifacts with their status and dependencies
Create artifacts in sequence until apply-ready

Use the TodoWrite tool to track progress through the artifacts.

Loop through artifacts in dependency order (artifacts with no pending dependencies first):
a. For each artifact that is
ready
(dependencies satisfied):
- Get instructions:
  bash
```
openspec instructions <artifact-id> --change "<name>" --json
```
- The instructions JSON includes:
  - context
    : Project background (constraints for you - do NOT include in output)
  - rules
    : Artifact-specific rules (constraints for you - do NOT include in output)
  - template
    : The structure to use for your output file
  - instruction
    : Schema-specific guidance for this artifact type
  - outputPath
    : Where to write the artifact
  - dependencies
    : Completed artifacts to read for context
- Read any completed dependency files for context
- Create the artifact file using
```
template
```
  as the structure
- Apply
```
context
```
  and
```
rules
```
  as constraints - but do NOT copy them into the file
- Show brief progress: "Created <artifact-id>"
b. Continue until all
applyRequires
artifacts are complete
- After creating each artifact, re-run
```
openspec status --change "<name>" --json
```
- Check if every artifact ID in
```
applyRequires
```
  has
```
status: "done"
```
  in the artifacts array
- Stop when all
```
applyRequires
```
  artifacts are done
c. If an artifact requires user input (unclear context):
- Use AskUserQuestion tool to clarify
- Then continue with creation
Show final status
bash
```
openspec status --change "<name>"
```

Output

After completing all artifacts, summarize:

Change name and location
List of artifacts created with brief descriptions
What's ready: "All artifacts created! Ready for implementation."
Prompt: "Run
```
/opsx:apply
```
or ask me to implement to start working on the tasks."

Artifact Creation Guidelines

Follow the
```
instruction
```
field from
```
openspec instructions
```
for each artifact type
The schema defines what each artifact should contain - follow it
Read dependency artifacts for context before creating new ones
Use
```
template
```
as the structure for your output file - fill in its sections
IMPORTANT:
```
context
```
and
```
rules
```
are constraints for YOU, not content for the file
- Do NOT copy
```
<context>
```
  ,
```
<rules>
```
  ,
```
<project_context>
```
  blocks into the artifact
- These guide what you write, but should never appear in the output

Guardrails

Create ALL artifacts needed for implementation (as defined by schema's
```
apply.requires
```
)
Always read dependency artifacts before creating a new one
If context is critically unclear, ask the user - but prefer making reasonable decisions to keep momentum
If a change with that name already exists, ask if user wants to continue it or create a new one
Verify each artifact file exists after writing before proceeding to next
