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: New 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 today.

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.

What it actually says

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). 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 argument after /opsx:new 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. 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:

    • A specific schema name → use --schema <name>
    • "show workflows" or "what workflows" → run openspec schemas --json and let them choose

    Otherwise: Omit --schema to use the default.

  3. 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.

  4. Show the artifact status

    openspec status --change "<name>" --json
    

    Use the returned planningHome, changeRoot, artifactPaths, and nextSteps instead of assuming repo-local paths.

  5. Get instructions for the first artifact The first artifact depends on the schema. 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.

  6. STOP and wait for user direction

Output

After completing the steps, summarize:

  • Change name and location
  • Schema/workflow being used and its artifact sequence
  • Current status (0/N artifacts complete)
  • The template for the first artifact
  • Prompt: "Ready to create the first artifact? Run /opsx:continue or just describe what this change is about and I'll draft it."

Guardrails

  • Do NOT create any artifacts yet - just show the instructions
  • Do NOT advance beyond showing the first artifact template
  • If the name is invalid (not kebab-case), ask for a valid name
  • If a change with that name already exists, suggest using /opsx:continue instead
  • Pass --schema if using a non-default workflow

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.
