What it does

Replica Test is an agent skill from Jakeschincariol/replica-skill. Clicks through every flow of an app clone and tests it for bugs: a test plan generated from the recon flows with happy paths and edge cases, Playwright end-to-end tests where possible, a browser click-through where not, and bug reports in a fixed format with severity, steps and evidence. Use when the user says "test my clone", "find bugs", "QA this", "click through everything", "write e2e tests", "does it work", or after /replica-build or /replica-backend.

Its SKILL.md is about 820 tokens, which your agent loads only when the skill is triggered. The skill folder holds 3 other files (for example `bug-report.md`, `e2e.example.spec.ts` and `test-plan.md`).

It sits in Testing & QA, covering Test generation, QA and bug reports and End-to-end testing. It works with Playwright. The repository describes itself as: Eleven free Claude skills that clone any app: reverse-engineer it, rebuild it, test it for bugs, then fix what its users hate. Free, MIT. The licence is MIT.

When your agent uses it

  • The user says test my clone
  • Click through everything
  • Write e2e tests
  • After /replica-build

Example prompts

  • “test my clone”
  • “find bugs”
  • “QA this”
  • “/replica-test”

Requirements

  • Node.js

Workflow steps

5 steps, taken from the step headings in SKILL.md.

  1. the plan
  2. automate what you can
  3. click through the rest
  4. report bugs
  5. fix loop

What it can do on your machine

Read from SKILL.md and the folder at commit 77c9436. 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

    Ships script files (TypeScript), which the agent can run.

    Shell commands in SKILL.md call:

    • npx
    • npm

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md. Its commands use npx and npm, which can reach the network depending on how they are called.

    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

Replica Test loads about 819 tokens when it runs. Until then it costs about 118 tokens; SKILL.md has 402 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~118
When it runs · the whole SKILL.md, loaded when a task matches
~819

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.

description
Clicks through every flow of an app clone and tests it for bugs: a test plan generated from the recon flows with happy paths and edge cases, Playwright end-to-end tests where possible, a browser click-through where not, and bug reports in a fixed format with severity, steps and evidence. Use when the user says "test my clone", "find bugs", "QA this", "click through everything", "write e2e tests", "does it work", or after /replica-build or /replica-backend.

replica-test

Reads the flows in replica/recon.md. Writes replica/test-plan.md, replica/bugs.md, and end-to-end tests in the project (e2e/). Templates in this folder: test-plan.md, bug-report.md, e2e.example.spec.ts.

The rule

Test your clone, not the original. Never load test, fuzz, script or hammer the original app's servers. Using the original by hand, as a normal user, to see how it behaves is fine.

Step 1: the plan

For every flow F01, F02... in the recon map, write:

  • Happy path: the steps, and what the user should see at the end.
  • Edge cases that apply. Go down this list for every flow: empty input, very long input, emoji and accents, two tabs at once, double click on submit, back button mid-flow, refresh mid-flow, slow network, offline, expired session, second user's data (must be invisible), time zones and daylight saving, mobile width, keyboard only, screen reader labels.
  • Negative cases: wrong password, card declined (Stripe test card 4000 0000 0000 0002), permission denied, deleted record.

Number every case: F01-H1, F01-E3, F01-N2.

Step 2: automate what you can

Playwright, one spec per flow, against the local dev server with seed data. Use roles and labels for selectors (getByRole('button', { name: 'Book' })), never CSS classes. See e2e.example.spec.ts.

bash
npm i -D @playwright/test && npx playwright install chromium
npx playwright test

Add to every spec: fail on console errors, fail on any 5xx response, and an axe accessibility scan (@axe-core/playwright) on each screen.

Step 3: click through the rest

What cannot be automated (emails arriving, OAuth with real providers, payments end to end, visual glitches) gets a manual pass. If a browser tool is available, drive the local clone with it and screenshot each step. Otherwise give the user the checklist and wait for answers.

Step 4: report bugs

Every bug goes in replica/bugs.md in the bug-report.md format: an ID, a severity, exact steps, expected, actual, evidence. Severity:

means
S1data loss, security hole, payments wrong, core flow blocked
S2a feature broken, no workaround
S3broken with a workaround, or visibly wrong
S4cosmetic

Only report what you reproduced. "Might be an issue" goes in a separate "to check" list.

Step 5: fix loop

Fix S1 and S2 first. For every fix: write the failing test first, fix, watch it pass, keep the test. Re-run the whole suite after each batch. Update bugs.md with the commit that fixed each one.

Output

test-plan.md, the specs, bugs.md, and a summary: cases run, passed, failed, bugs by severity, fixed so far. Ship nothing with an open S1. Next: /replica-diff.

When should I use Replica Test?

Replica Test fits situations like: the user says test my clone; click through everything; write e2e tests; after /replica-build.

How do I install Replica Test in Claude Code?

Run `npx skills add Jakeschincariol/replica-skill --skill replica-test -a claude-code`. Or copy the skill folder (replica-test in Jakeschincariol/replica-skill) into .claude/skills/replica-test in your project. Claude Code loads it when a task matches its description.

Can I use Replica Test in Cursor, Gemini CLI or GitHub Copilot?

Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add Jakeschincariol/replica-skill --skill replica-test -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/replica-test, .gemini/skills/replica-test, .github/skills/replica-test and .opencode/skills/replica-test in your project.

What does Replica Test need to run?

Going by SKILL.md and its folder, Replica Test needs TypeScript for the scripts in its folder and the command-line tools its instructions call (npx and npm). Our summary lists: Node.js.

Does Replica Test access the network?

SKILL.md contains no URLs. Its commands use npx and npm, which can reach the network depending on how they are called. This is read from the text; nothing was executed.
