mvp-spec

mvp-spec is a command for coding agents from jcarlosrodicio/opencode-agent-orchestration-kit. It costs 21 tokens per session (120 once invoked), scanned A, original, Apache-2.0.

A command for researching and writing a strict minimum viable product (MVP) plan: the smallest useful first version of a product. It breaks the work into tasks intended to take one or two hours.

In plain words
What is it for?
Use it to define a small product scope, list what is explicitly excluded, and give each task acceptance criteria and a way to validate it.
Why use it?
It prevents early plans from growing into speculative architecture, platform work, or polish that the first version does not need.

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

mvp-spec 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.

What it actually says

Create a strict MVP spec for:

$ARGUMENTS

Use the /scope flow only: researcher -> scoper synthesis -> specifier.

Additional constraints:

  • Keep the MVP minimal.
  • Prefer tasks sized for 1-2 hours.
  • Make out of scope explicit.
  • Avoid speculative platform, architecture, or polish work.
  • Include acceptance criteria and validation for every task.
  • Stop if research is not ready for spec.

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.
