What it does

Supercheck Testing QA is an agent skill from supercheck-io/supercheck. Test or validate Supercheck changes using package checks, Jest, Playwright UI/API E2E, recorder browser tests, contract tests, AI SRE acceptance, release evidence, and commit/merge readiness gates.

Its SKILL.md is about 940 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 Testing & QA, covering Site reliability engineering, Unit testing and End-to-end testing. It works with Playwright and Jest. The repository describes itself as: Open-Source Testing, Monitoring, and AI SRE — as Code. The licence is AGPL-3.0.

Example prompts

“/supercheck-testing-qa”

What it can do on your machine

Read from SKILL.md and the folder at commit 0c077d0. 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 mermaid).
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

Supercheck Testing QA loads about 942 tokens when it runs. Until then it costs about 55 tokens; SKILL.md has 341 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it: ~55
When it runs · the whole SKILL.md, loaded when a task matches: ~942

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.

Supercheck testing and quality assurance

mermaid

flowchart LR
  STATIC[Typecheck and lint] --> UNIT[Unit tests]
  UNIT --> CONTRACT[Integration and contract tests]
  CONTRACT --> E2E[Browser E2E]
  E2E --> DEPLOY[Exact-SHA deployment]
  DEPLOY --> ACCEPT[Provider/manual acceptance]

Package boundaries

Run app commands from app, worker commands from worker, CLI commands from cli, recorder commands from recorder, and docs commands from docs.
Inspect each package’s current scripts instead of assuming command names.
Start with the narrowest test proving the changed behavior, then broaden based on blast radius.
App/worker shared contracts require producer and consumer coverage. Schema changes require generated migration and schema-contract verification.
CLI changes require typecheck, lint, Jest, build, and package-content validation.
Recorder changes require unit/security tests, lint, vendored Playwright/CRX/example/test-extension builds, and browser suite acceptance.

Test design

Test observable behavior and invariants, not implementation wording.
Include happy path, validation failure, authorization denial, tenant isolation, dependency failure, timeout/cancellation, retries/idempotency, and cleanup where applicable.
Use deterministic clocks/IDs/providers where useful without bypassing production logic.
Do not weaken assertions, add unconditional retries, inflate timeouts, or disable security controls merely to obtain green output.
Browser tests cover routing, auth, focus/accessibility, streaming, extension messaging, and integrated user flows that lower-level tests cannot prove.

Evidence

Record exact command, revision/worktree state, pass/fail/skip counts, relevant environment, and artifacts.
A test that did not execute is not a pass. Classify application regression, fixture defect, sandbox/network limitation, browser/platform incompatibility, or external-account gate.
Screenshots, traces, reports, and logs are evidence only when tied to the tested revision and scenario.
Confirm generated outputs, reports, coverage, auth state, and temporary fixtures are ignored/removed before commit.

AI SRE acceptance

Use disposable non-production incidents, services, connectors, provider accounts, and scoped users.
Prove RBAC and tenant denial before provider/tool execution.
Cover streaming/persisted message identity, connector and private-agent behavior, cancellation, provider/tool failure, rate limits, durable usage, billing exactly-once behavior, and cleanup.
Never use customer data/credentials, grant cluster-admin, disrupt production, exhaust quotas, or repeat a paid scenario with no new decision value.

Readiness gates

mermaid

flowchart TD
  REVIEW[Source and diff reviewed] --> TEST{Relevant local checks pass?}
  TEST -->|no| BLOCK[Not commit-ready]
  TEST -->|yes| STATE{No accidental or hidden files?}
  STATE -->|no| BLOCK
  STATE -->|yes| COMMIT[Commit-ready]
  COMMIT --> CI[Required CI]
  CI --> DEPLOY[Exact-SHA acceptance]
  DEPLOY --> GA[Merge/release-ready]

Commit readiness requires reviewed changes, relevant local checks, docs/skill parity, clean diff checks, and disclosed test boundaries.
Merge requires required CI and review policy.
Release/GA additionally requires exact deployed SHA, migration health, zero unexpected acceptance failures, browser evidence, RBAC/flags, worker/control-plane observation, provider/billing acceptance where relevant, and fixture cleanup.
