go-nogo-memo is a skill for Claude Code from stanislavnianko/product-discovery-claude-skills. It costs 66 tokens per session (1,155 once invoked), scanned A, original, MIT.

A decision document that summarizes the available evidence and recommends whether a project should proceed, change direction, or stop. The agency recommends; the client or other decision-owner decides.

In plain words
What is it for?
Use it at the end of product discovery, or after major new evidence, to support a go, no-go, or pivot decision.
Why use it?
It brings scattered research, assumptions, gaps, risks, and options into one document for a clear decision.

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

go-nogo-memo 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 12d 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.

Go / No-Go Memo

Part of the discovery-phase skill pack · deliverables group · reads discovery-context.md (run profile-builder first if missing).

The terminal decision document. Everything before this fed into it; everything after follows from it. In outsourcing, the agency recommends, the client decides — the memo must support both perspectives.

When to run

  • End of any discovery cycle
  • Standalone if BA brings in evidence from elsewhere and just needs to write the memo
  • Re-run after major new evidence (re-versioned)

Differs from proposal: proposal is commercial (here's what we'd do, please sign); memo is decisional (here's what we believe, please decide). They can co-exist.

Step 1 — Read context + scan evidence

Read discovery-context.md (section 5. Expected deliverable). Then scan ./discovery/ for available artifacts — even partial discovery can produce a memo, but flag the gaps explicitly in the memo's "Evidence" section.

If discovery-context.md is missing, ask the BA inline: "who's the decision-owner (client / agency / both) and what decision are we framing (proceed / pivot / kill)?" — tag the output [ASSUMED FRAMING]. Never block; recommend profile-builder for high-stakes work.

Step 2 — Force the decision first

Before writing anything, ask the BA:

"Based on what we have, what's the recommendation: GO / PIVOT / KILL? One word. We'll justify on paper next."

If they hesitate, probe:

  • "What's the one finding that would flip this to the opposite answer?"
  • "If you had to bet 10% of the agency's quarterly capacity (or your own time) on this, would you?"
  • "Imagine this memo arrived from another team. Would you approve their recommendation?"

The memo serves the recommendation. No defensive prose.

Step 3 — Clarify the decision split (outsourcing)

Two roles must be explicit:

  • Recommendation owner — the agency BA / lead. Owns the recommendation in the memo.
  • Decision owner — typically the client (per discovery-context.md engagement). The memo gives them what they need to decide.
