spec-draft

A guided command for starting a product specification: a written description of what the product does and how people use it. It interviews you and saves a rough first draft in docs/project-spec.md.

In plain words
What is it for?
Use it to define the core problem, users, workflows, user roles, external services, and what counts as complete for the first version.
Why use it?
It turns an incomplete idea into a shared description before framework, database, or library choices distract from the actual user needs.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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

spec-draft 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 2d 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

You are running Step 1 of the Vibe-Spec spec-driven workflow: writing a V0 spec. Consult the vibe-spec skill (${CLAUDE_PLUGIN_ROOT}/skills/vibe-spec/reference/00-workflow.md) for the full methodology.

The goal of V0 is a rough first draft. It is intentionally tool-agnostic — do not choose frameworks, databases, or libraries yet. Capture what the product does and how users interact with it.

What to do

  1. If $ARGUMENTS (the idea) is empty, ask the user for a one-line description of what they want to build.
  2. Interview the user to fill in the essentials. Ask about, at minimum:
    • The core problem the product solves and who it's for
    • The exact user workflows — e.g. "user logs in with OTP, sees a dashboard; pages differ by role; the app ingests data from an external API on a schedule"
    • Distinct user types / roles, if any
    • External systems it talks to (webhooks in/out, third-party APIs, scheduled jobs)
    • What "done" looks like for a first version Ask in small batches; don't overwhelm. Accept that the user won't know everything yet — that's fine for V0.
  3. Write the result to docs/project-spec.md with a clear heading marking it as V0. Structure it as: product summary, user types, user workflows (the bulk), external integrations, and open questions you couldn't resolve.

Keep it high-level and readable. Do not map features to tools — that's /spec-refine (Step 2). End by telling the user to run /spec-refine next.

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.

spec-draft is a command published in the GitHub repository Connorrmcd6/vibe-spec (9 stars, last pushed 1mo ago), licensed MIT. It adds 40 tokens to every session and 440 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
