using-startup-superpowersUse at the start of any conversation about a startup idea, product validation, founder strategy, or work inside a startup/ workspace.
Using Startup Superpowers is an agent skill from davepoon/buildwithclaude. Use at the start of any conversation about a startup idea, product validation, founder strategy, or work inside a startup/ workspace. Establishes file conventions, voice-input handling, subagent dispatch rules, and how to update each artifact safely. Activate before invoking any other startup-superpowers skill.
Its SKILL.md is about 1.8k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
It sits in Agent Workflows, covering Subagents. The repository describes itself as: A single hub to find Claude Skills, Agents, Commands, Hooks, Plugins, and Marketplace collections to extend Claude Code, Claude Desktop, Agent SDK and OpenClaw. The licence is MIT.
Read from SKILL.md and the folder at commit 10bfc43. It shows what the files ask for, not the result of running them.
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.
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.
Hosts in commands or code, which the agent is likely to contact:
tally.soFrom URLs in SKILL.md, links to its own repository left out.
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Using Startup Superpowers loads about 1.8k tokens when it runs. Until then it costs about 85 tokens; SKILL.md has 898 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.
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.

.claude/skills/using-startup-superpowers/SKILL.md (or your agent's skills folder).This skill carries the always-on context for the startup-superpowers plugin. When it activates, treat its contents as plugin-wide ground rules — file formats, voice-input handling, subagent dispatch — that apply across every other startup-superpowers skill. It is not a workflow to execute; it is the shared backdrop you operate against.
Load this before invoking whats-next, competitors, hypotheses, interviews, market-research, surveys, or mvp.
The founder may be using voice input. Voice transcription is unreliable with proper nouns — competitor names, product names, URLs, technical terms, and non-English words often come through garbled. When the input contains something that looks like a misheard name or an unintelligible fragment, ask the founder to clarify or spell it out rather than guessing.
The source of truth for the project definition is startup/core.md. It is a markdown file with:
version (format version) and name (working project name)## Seed Description section with the founder's original description of what they're building## Core section with structured fields as - **Key:** Value list items (audience, problem, solution, geography, etc.) — these accumulate as the onboarding conversation progressesRead startup/core.md at the start of any conversation that touches the startup idea, product, or strategy.
When updating core.md, read the current file first, modify the fields you need under ## Core (using - **Key:** Value format), and write the file back. Leave the frontmatter and ## Seed Description untouched. Propose changes to the founder and get confirmation before writing. Fields missing from ## Core are not yet defined — don't push to fill everything at once.
The project plan lives in startup/plan.md. It tracks the founder's current focus, next steps as a checklist, and a log of past assessments. The whats-next skill manages it — don't update it directly. When the founder asks about direction or next steps, invoke the whats-next skill which dispatches the lean-startup-advisor subagent for an independent assessment.
Hypotheses are testable assumptions about the project — things the founder believes but hasn't validated yet. Each hypothesis is a .md file in startup/hypotheses/.
Format: YAML frontmatter with status (untested/confirmed/invalidated), an H1 title (the testable statement), an Obsidian tag for type (#problem, #solution, #willingness_to_pay, #urgency, #other), a description, and an optional ## Notes section.
When the founder mentions a new assumption or risk in conversation, suggest capturing it as a hypothesis. Read the hypotheses folder before any conversation about validation, interviews, or pivots. To update a hypothesis, read the file first, propose the change, get confirmation, then write it back.
Competitors are tracked as individual .md files in startup/competitors/.
Format: YAML frontmatter with type (direct/indirect) and url (competitor's website), an H1 heading with the competitor name, and sections for Description, Core Features, and Notes.
When the founder mentions a competitor or asks about the competitive landscape, read the competitors folder for context. To add or update a competitor, follow the file conventions and get confirmation before writing.
A web-researcher subagent is available for any research task that goes beyond a quick search — competitive landscape discovery, problem space validation, market signals, community discussion. Use it when the founder asks to research something or when research would meaningfully sharpen an assumption or decision.
Research summaries from web-researcher runs are saved to startup/research/ as dated .md files. This preserves expensive research for future reference. The calling skill is responsible for writing the file after getting the agent's output.
At a few high-value milestones, offer the founder an optional, anonymous feedback link. This is the plugin's only feedback mechanism — there is no telemetry and nothing is ever sent automatically. Everything here is advisory and founder-driven.
The ledger. Invite state lives in startup/.superpowers/feedback.md, created lazily on the first invite:
---
opted_out: false
---
# Feedback invites (managed by Startup Superpowers — safe to delete)
- competitors-done — invited 2026-05-31opted_out: true → never invite for any milestone again.{stage-tag} — invited {YYYY-MM-DD} line means that milestone was already offered. One invite per stage tag, ever — the "first time only" behavior falls out of this; no counting needed.Before inviting at any milestone, read startup/.superpowers/feedback.md (if it doesn't exist, treat it as "nothing invited, not opted out"). Stay silent if it shows opted_out: true or already lists the stage tag. Otherwise emit the invite, then append the {stage-tag} — invited {today} line, creating the file and startup/.superpowers/ folder if absent.
Milestones and stage tags — each owned by the skill that produces the artifact:
| Stage tag | Fires when |
|---|---|
competitors-done | first startup/competitive-landscape.md written |
first-interview-analyzed | first startup/interviews/*.md analysis written |
mvp-designed | first startup/mvp-plan.md written |
market-brief-done | first startup/market-brief.md written |
The invite — one warm, milestone-specific sentence tied to the win the founder just got, then the link, then the opt-out clause:
"Before you go — {one line tying to what they just received}. If you've got 60 seconds, here's a quick, anonymous form:
https://tally.so/r/Bz0ArK?stage={stage-tag}. Totally optional, and just say the word if you'd rather I never bring this up again."
https://tally.so/r/Bz0ArK?stage={stage-tag}.stage value is the only thing that travels with the link, and only if the founder submits — no identity, no project content.Status: live. The form id is set below (Bz0ArK), so invites are active. (Guard: if the id is ever reset to the literal {FORM_ID} placeholder, treat the protocol as inert and do not emit any invite.)
Opt-out. If the founder ever says "stop asking" / "don't bring this up again," set opted_out: true in the ledger and confirm briefly. Never ask again.
FORM_ID: Bz0ArK <!-- Live Tally form: https://tally.so/r/Bz0ArK . Reset to the literal {FORM_ID} placeholder to make invites dormant again. -->
