app-teardown

app-teardown is a skill for Claude Code from LucasSantana-Dev/sharekit. It costs 152 tokens per session (1,177 once invoked), scanned A, original, MIT.

A product teardown is a structured review of a live web app, SaaS product, or mobile app by using its real flows. It records useful patterns and evidence, then decides what to adopt, adapt, keep, or reject.

In plain words
What is it for?
Use it to study another product's user experience, features, visual design, wording, or growth methods before building your own.
Why use it?
It turns competitor research into concrete decisions instead of a general tour or list of impressions.

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

app-teardown 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.

App Teardown

Studies a live product the way a chef eats at a rival's restaurant: walk the real flows, name what works, explain WHY it works for them, and decide what transfers to our context. The output is a decision artifact, not a tour.

Use When

  • A live app/product should be mined for ideas applicable to one of our projects.
  • Before building a surface that a named competitor/product already does well.
  • User names a product and asks what to learn, steal, or adapt from it.

Do Not Use When

  • Target is a repo/codebase → code-teardown.
  • Only visual direction is wanted (moodboard, type, palette) → frontend-reference-hunt.
  • Understanding OUR OWN system's internals → doc-and-modernize.

Inputs / Prereqs

  • Target URL + whether login is needed (drive the user's Chrome via claude-in-chrome).
  • OUR context lock: which project the ideas land in, its goals and constraints.
  • Memory state-check FIRST: reference_<target>_evaluated_* note exists → surface prior outcome and stop unless the revisit condition is met.

Workflow

  1. Scope + constraint capture — target, key flows to walk, and the gate question: why does their design work FOR THEM (scale, audience, pricing model, compliance, platform, legacy)? Record it; it powers the cargo-cult gate later.
  2. Live exploration (claude-in-chrome) — walk onboarding, core flow, settings, empty states, error recovery, upgrade/paywall moments. Screenshot each finding into <project>/.claude/design/refs/. Note deliberate ABSENCES and simplifications too.
  3. Map by dimension — UX (interaction, feedback, empty/error states), Features (jobs-to-be-done, scope cuts, free-vs-paid line), Visual design (type, spacing, components, motion), Copy (tone, terminology), Growth (activation, referral, retention hooks). 2+ dimensions minimum; skip dimensions irrelevant to the brief.
  4. State-check per candidate finding — do WE already have it? Query graphify (graphify query) when the target project has graphify-out/, plus grep/memory. Mark hits already-have instead of re-proposing them.
  5. Verdict + rationale per finding — apply the contract in references/teardown-contract.md: evidence, adopt | adapt | already-have | reject, the mandatory constraint rationale ("[their constraint] → [applies to us?] → [action]"), effort, landing spot in our repo.
  6. Emit + remember — report to <project>/docs/reference/<target>-teardown-<date>.md (committable). Memory note reference_<target>_evaluated_<date>.md with outcome + revisit condition; an "evaluated → nothing" outcome is a valid, valuable result (prevents re-evaluation — megabrain/llmwiki precedent). Summary line: "N findings, A adopt, D adapt, H already-have, R rejected".

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.
