product-os: Command for Claude Code

.claude/commands/create-new-project.md

create-new-project is a command for Claude Code from motorway-sandbox/product-os. It costs 0 tokens per session (2,205 once invoked), scanned A, original, MIT.

A guided project-document creator that uses a standard template and questions to develop an experiment or project plan. It also reviews the document against stated quality criteria.

In plain words
What is it for?
Start a new project or experiment document, clarify its goals and assumptions, and review whether the plan is well defined.
Why use it?
It helps turn an incomplete idea into a clearer plan by asking about the problem, evidence, alternatives, users, and measures of success.

Command for Claude Code

This is motorway-sandbox/product-os's own configuration. It tells Claude Code how to work on product-os 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 product-os 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

create-new-project 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 5d 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.

The opening of the file, as written. The whole thing — 232 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Create New Project

Create a new experiment/project document using the standard template, complete it through guided conversation, and ensure quality through review criteria and Socratic questioning.

Instructions

Phase 1: Gather Project Information

  1. Start the conversation by asking the user for the project/experiment name and a brief description of what they want to achieve.

  2. Use Socratic questioning to help the user think through the project. Ask 3-5 questions from the categories below (pick the most relevant):

    Problem Clarity:

    • "What specific user pain point does this solve?"
    • "How do we know this is a real problem? What evidence do we have?"
    • "Who experiences this problem most acutely?"
    • "What's the cost of NOT solving this?"

    Solution Validation:

    • "Why is this the right solution for that problem?"
    • "What alternatives did you consider? Why did you reject them?"
    • "What's the simplest version that solves the core problem?"
    • "How will users discover this feature?"

    Success Criteria:

    • "How will we know if this feature is successful?"
    • "What would make you consider this a failure?"
    • "What metric are we trying to move? By how much?"
    • "What's the adoption target?"

    Constraints & Trade-offs:

    • "What are the technical constraints or risks?"
    • "What are we NOT going to do as part of this?"
    • "What existing features or workflows does this affect?"
    • "If we had half the time/resources, what would we cut?"

    Strategic Fit:

    • "Why is this the right feature to build RIGHT NOW?"
    • "How does this fit into our broader product strategy?"
    • "What happens if we wait 6 months to build this?"
    • "How does this affect our competitive position?"
  3. Gather specific template fields through conversation:

    • Objective (clear, measurable goal)
    • Hypothesis (if we do X, then Y will happen because Z)
    • Evidence (user research, data, competitive analysis)
    • Success metric (primary KPI)
    • Secondary metrics
    • Guardrail metrics (what we don't want to negatively impact)
    • ROTI score estimate (Expected impact / dev days)
    • Evaluation plan: what to evaluate, criteria, method (Logfire/manual/hybrid), baseline, frequency, owner
    • Experiment details (if applicable): test type, audience, run time, MDE/ROPE
    • Launch and end dates
    • Solution details: link, scope, build time, out of scope, key assumptions
    • Risks and mitigations: impact, technical, internal, monitoring plans
    • Cross-functional stakeholders
    • Next steps

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.
