What it tells the agent

The instruction file, verbatim from the audited commit — this is the text the model reads, and the surface the audit's instruction layer examines. Quoted here so you can judge it without cloning anything.

---
name: openspec-propose
description: Propose a new change with all artifacts generated in one step. Use when the user wants to quickly describe what they want to build and get a complete proposal with design, specs, and tasks ready for implementation.
license: MIT
compatibility: Requires openspec CLI.
metadata:
  author: openspec
  version: "1.0"

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**

1. **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.

2. **Create the change directory**
   ```bash
   openspec new change "<name>"
   ```
   This creates a scaffolded change at `openspec/changes/<name>/` with `.openspec.yaml`.

3. **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

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:
        ```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

5. **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

Questions

What does the Openspec Propose skill do?

The Agent Harness for AI-Human Collaboration, inspired by the AI-DLC (AI-Driven Development Lifecycle)

Is Openspec Propose safe to install?

The audit found nothing in the source that contradicts what it says it does, and graded it B (89/100). Grade A is held back for packages that have also passed a sandboxed behavioural run, which is why a clean skill reads B.

What can Openspec Propose access on my machine?

The audit observed no filesystem, network or shell use at all in its source.

How current is this page?

The grade is for one exact copy of the source (3bb5b08404b5), read on 2026-10-12. The repository is watched, and a new audit runs when it changes — this is the first audit.
