What it does
Validate Idea is an agent skill from menkesu/awesome-pm-skills. Turns a product or startup idea into a ranked list of riskiest assumptions, the cheapest test for each, pass/kill thresholds, and a go/pivot/kill readout, before anyone builds. Use when someone says "validate my idea", "is this worth building", "what's the riskiest assumption", "design an MVP", "fake door", "smoke test", "will people pay", "pre-sell", "customer discovery plan" or "should we build this". Draws on 82 Lenny's Podcast guests incl. Mike Maples Jr., Eric Ries and Jake Knapp.
Its SKILL.md is about 4.6k tokens, which your agent loads only when the skill is triggered. The skill folder holds 5 other files, including reference files and assets (for example `references/frameworks.md` and `references/quotes.md`).
It sits in Testing & QA, covering Podcasting and QA and bug reports. The repository describes itself as: Product management workflows grounded in Lenny's Podcast, for Claude Code, Codex, and Cursor.
When your agent uses it
- Someone says validate my idea
- Is this worth building
- Whats the riskiest assumption
- Will people pay
Example prompts
- “validate my idea”
- “is this worth building”
- “s the riskiest assumption”
- “/validate-idea”
Workflow steps
3 steps, taken from the step headings in SKILL.md.
- Diagnose (ask before answering)
- Pick the play
- Run it
What it can do on your machine
Read from SKILL.md and the folder at commit c1b6e2d. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
No scripts in the folder and no shell commands in SKILL.md (its code samples are markdown).
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Validate Idea loads about 4.6k tokens when it runs, and up to ~10k if it reads all its reference files. Until then it costs about 126 tokens; SKILL.md has 2,579 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.
SKILL.md
Its licence (Custom licence) doesn't allow us to republish the file, so here is its outline and opening line. It has 2,579 words (~4,565 tokens).
“Riskiest assumptions first, cheapest test next, a pre-committed kill line, then a decision, all before building. Built from 182 insights from 82 Lenny's Podcast guests. Lead team: Mike Maples Jr., Eric Ries, Jake Knapp.”
