.claude/commands/opsx/propose.md

OPSX: Propose is a command for Claude Code from mendix/web-widgets. It costs 21 tokens per session (1,090 once invoked), scanned A, a copy of OPSX: Propose, Apache-2.0.

A command for proposing a new software change and generating its proposal, design, and task documents.

In plain words
What is it for?
It helps name a change, place it in the correct package, and create the planning artifacts for it.
Why use it?
It turns a feature or fix description into a documented plan before implementation begins.

Command for Claude Code

Written for Claude Code: installed under .claude/. Also seen: names the AskUserQuestion tool.

This is mendix/web-widgets's own configuration. It tells Claude Code how to work on web-widgets itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything web-widgets configures →

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: Propose 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 1mo 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 — 121 lines — stays where its author put it; the contents beside it link to each section on GitHub.

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 argument after /opsx:propose is the change name (kebab-case), OR a description of what the user wants to build.

Steps

  1. If no 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.

  2. Create the change directory (inside the target package)

    Specs/changes are PER-PACKAGE. First determine which package this change belongs to (ask the user if unclear), then cd into it before running openspec. NEVER create changes at the monorepo root — a guardrail hook blocks it.

    cd PACKAGE_DIR && openspec new change "CHANGE_NAME"
    

    This creates a scaffolded change at <package-dir>/openspec/changes/<name>/ with .openspec.yaml. If the package has no openspec/ yet, run openspec init inside the package first.

  3. Get the artifact build order

    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
  4. 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:
      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 "

    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
  5. Show final status

    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 to start implementing."

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

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.
