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

dry-run 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 11d 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.

What it actually says

MorningStar Dry Run

Fetch a Notion PRD and generate a task plan without executing anything. Use this to preview what the agent would do before committing to a full run.

Arguments

User provided: $ARGUMENTS

Parse the notion-url (required): Notion page URL or ID containing the PRD.

Instructions

  1. Fetch the PRD from the provided Notion URL
  2. Analyze the codebase in the current working directory
  3. Generate a task list of what needs to be built
  4. Display the plan as a numbered list with:
    • Task ID
    • Title
    • Files to modify
    • Acceptance criteria
  5. Do NOT execute any tasks, write any code, or make any commits
  6. Report the estimated number of tasks and approximate cost

Example

/morningstar:dry-run https://notion.so/My-PRD-abc123
Changes

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.
