recipe-validate

recipe-validate is a skill for Claude Code, Codex from shinpr/claude-code-discover. It costs 26 tokens per session (1,245 once invoked), scanned A, original, MIT.

A guided workflow for testing product assumptions with methods suited to each risk, such as prototypes, code analysis, market research, or expert review.

In plain words
What is it for?
Use it to assess hypotheses, choose validation methods, run the applicable specialist checks, and record results in hypothesis files.
Why use it?
It helps determine whether an assumption is supported before committing to development and adds an independent attempt to disprove it.

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

recipe-validate 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.

How it starts

The opening of the file, as written. The whole thing — 120 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Context: Validate hypotheses using appropriate methods based on risk type. Always invoke hypothesis-verifier for an independent disconfirming pass. Record results in hypothesis files.

Orchestrator Definition

Execution Protocol:

  1. Required specialist execution: Invoking this recipe is the user's explicit instruction and authorization to execute every named specialist whose condition applies. Execute each applicable Agent call with its declared subagent_type when its prerequisites are met and continue from its returned result; equivalent orchestrator work does not complete that step
  2. Exact specialist handoff: The complete Agent prompt consists of all and only the applicable canonical field: value entries declared by the specialist's Input Contract or, for a built-in specialist, by the call site's inline contract. Copy each value unchanged from its authoritative source; serialize path fields as path strings so the specialist reads referenced artifacts directly
  3. Follow the validation flow defined below
  4. Approval gates: At each [STOP — BLOCKING], present the named decision and resume after explicit user confirmation

Workflow

Assess the hypothesis → independently design and approve the smallest disconfirming test → execute it → record and review the result.

Execution Decision Flow

1. Hypothesis Assessment

Input: $ARGUMENTS

Read the target hypothesis file(s). Understand:

  • What is being tested (the hypothesis statement)
  • Which risk dimension is primary (Value / Usability / Feasibility / Viability)
  • Current confidence scores
  • Time budget and deadline
  • Parent Opportunity context

2. Validation Design

Invoke hypothesis-verifier using Agent tool (subagent_type: "discover:hypothesis-verifier") with hypothesis_path: <target hypothesis path> to design the validation:

  • hypothesis-verifier operates in a separate context to preserve an independent disconfirming pass
  • It defines success/failure criteria independently

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.

recipe-validate is a skill published in the GitHub repository shinpr/claude-code-discover (10 stars, last pushed 7d ago), licensed MIT. It adds 26 tokens to every session and 1,245 once invoked, about $0.0001 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.
