qualiow-exploratory-testing

AI-powered exploratory testing for web, mobile and backend/API — Claude Code skills, a QA knowledge base, and the CLI that wires them into a project.

Claude acts as a Principal QA Engineer: it understands the business first, risk-ranks what matters, explores systematically, and writes bug reports an executive can act on. No test scripts and no framework — AI reasoning, browser/device commands, and QA heuristics.

| Surface | Driver | Skill | |---------|--------|-------| | Web app in a desktop browser | playwright-cli | /qa-explore, /qa-explore-quick | | Native iOS/Android app, or a web app in real Simulator Safari / Emulator Chrome | bin/mobile-cli.mjs (Maestro shim) | /qa-explore-mobile | | Acceptance criteria with no UI at all — tables, streams, queues, IAM, HTTP endpoints | git show, read-only aws-cli, authenticated fetch | /qa-verify-backend |

Requirements

• Node.js >= 22.4 (node --version)
• Claude Code — the skills run as slash commands inside it
• playwright-cli ships as a dependency of this package; nothing extra to install for the web path. Mobile needs the iOS/Android toolchains — see docs/MOBILE-SETUP.md.

Install

Three supported paths. Pick one.

1. npm (recommended for a project)

npm install -g qualiow-exploratory-testing
cd my-project
qualiow init

qualiow init copies into the current project:

| Copied | To | |--------|----| | the 11 skills | .claude/skills/qa-*/ | | the five sub-agents | .claude/agents/ | | knowledge base, domain profiles (*.yml), templates, security policy | data/ | | _default.yml target (with --include-examples: the _example-*.yml templates and the parabank.yml and saucedemo.yml demo targets) | data/targets/ | | the mobile driver, setup-mobile.sh, doctor-mobile.sh (executable) | qa/bin/ | | the credential template | qa/.env.example |

It also creates output/{sessions,bugs,context}, .auth/ and qa/, and appends a # Qualiow block to .gitignore (.auth/, .env, qa/.env, output/sessions/*/, !output/sessions/INDEX.md, output/context/*.md, data/targets/local-*.yml, .playwright-cli/, *.trace.zip, *.webm).

Re-running init is a no-op — existing files are kept unless you pass --force, and --dry-run prints the plan without writing anything. Add --hooks to install the three guard hooks into the project as well — see Hooks.

cp qa/.env.example qa/.env      # credentials live here, never in YAML
npx playwright-cli install --skills   # optional: the official Playwright skill alongside
/qa-explore https://your-app.com      # inside Claude Code

2. Claude Code plugin

claude plugin marketplace add willcoliveira/qualiow-exploratory-testing-skills
claude plugin install qualiow@qualiow

The repository is its own marketplace (.claude-plugin/marketplace.json), so those two commands are the whole install. For development against a local checkout, point Claude Code at the directory instead:

claude --plugin-dir /path/to/qualiow-exploratory-testing-skills

Skills appear namespaced: /qualiow:qa-explore, /qualiow:qa-verify-backend, and so on. Data (knowledge, domains, templates, targets) resolves from ${CLAUDE_PLUGIN_ROOT}/data/ unless the project you are in has its own data/ or qa/ directory, which wins.

bin/ lands on PATH only for marketplace installs — with --plugin-dir, call the driver by its full path, ${CLAUDE_PLUGIN_ROOT}/bin/mcli.

Under a plugin install the qualiow CLI runs through bin/qualiow, a launcher shim: it uses the local build when the checkout has one, and otherwise fetches the published npm package with npx, pinned to the version in .claude-plugin/plugin.json. A plugin install has no dist/, so the first run of that path needs network.

3. Git checkout (contributors, dogfooding)

git clone https://github.com/willcoliveira/qualiow-exploratory-testing-skills.git
cd qualiow-exploratory-testing-skills
npm install
npm run build
npm test

.claude/skills/ and .claude/agents/ are canonical. skills/ and agents/ are generated mirrors (shipped to npm and used by the plugin) kept in sync by npm run sync:plugin; CI fails on drift, so never hand-edit the mirrors.

CLI

The CLI is the plumbing around the skills — project setup, config validation, session listing, report export. The exploratory sessions themselves run inside Claude Code, not from the shell.

| Command | Flags | What it does | |---------|-------|--------------| | qualiow init | --include-examples --force --dry-run --hooks | Install skills, sub-agents, data, qa/bin/ and the output tree into the current project. Idempotent. --hooks also copies the guard scripts to qa/hooks/ and merges the hook and permission entries into .claude/settings.json | | qualiow explore [url] | -t <target> -c <context> --time-box 45m --dry-run | Pre-flight only. Validates the inputs, creates the session directory skeleton, and prints the /qa-explore … --session <dir> command to paste into Claude Code. It does not drive a browser | | qualiow validate | --targets --domains --knowledge --kb --all | Validate configs against their schemas; exits 1 on any failure. --all also checks a project-local qa/target.yml and cross-checks the knowledge base against its manifest | | qualiow list <type> | sessions | knowledge | targets | domains; for knowledge also --domain --tag --type --entry <id> --changelog --stats | List what is installed or recorded. list knowledge --entry <id> prints that entry's YAML; --changelog and --stats read the knowledge changelog and the manifest counts | | qualiow report | -s <id>\|latest -f md\|html\|json\|jira -o <file> --stdout | Export an existing session. -o is confined to output/ (relative paths resolve inside it; .. is refused). md writes session-summary.md; html/json/jira carry the confidentiality header and pass through redaction | | qualiow kb <sync\|check> | — | Regenerate or validate data/knowledge/manifest.yml from the release files | | qualiow kb digest | --for explore\|backend\|mobile --domain <id> --tag <t...> --entry <id> --data <dir> --max-lines <n> | Print a compact digest of the knowledge entries a session needs, instead of the manifest and the entries read whole. --entry <id> prints one entry in full | | qualiow session finalize <dir\|latest> | --check --redact | Close a session: validate it against the output contract, then append the INDEX row, the bug rows and the metrics line. --check writes nothing; --redact rewrites files that still carry a secret. A contract-2 session is refused while its areas, evidence or bug areas fail the checks or its coverage level is missing or stale | | qualiow session level <dir> | --write | Validate a contract-2 session (/qa-explore, /qa-explore-quick) and print its coverage level, overall and per risk tier, with a separate findings line and a "To raise this level" list. --write writes evidence-level.md, backlog.md and stats.coverage_level; refused once the session is finalized | | qualiow session continue-check <name\|latest> | --target <id> (required) | Read-only. Checks one finalized contract-2 explore session of the same target and prints the only carry-forward /qa-explore --continue gets: a fenced, redacted, path-only summary of its risk rows, backlog and site map | | qualiow session list | — | The session listing, same as list sessions | | qualiow session archive <dir> | --remove | Tar the session directory; --remove also deletes it and marks its INDEX row archived | | qualiow session delete <dir> | --yes | Remove a session directory and its index rows. Dry-run until --yes | | qualiow session prune | --older-than <days> --yes | The same, for every session older than N days | | qualiow judge triage <claim-file> | --target <id> --out <dir> --evidence-max-lines <n> --dry-run --mock <json> --provider typesafe\|laya --endpoint <url> | Opt-in, advisory. Asks a decision model typed questions about one claim card and records the answers beside the judge's verdict. Sends nothing unless the target sets verification.mode: triage-shadow and lists the provider; exit 2 = not enabled (nothing sent), 3 = unavailable | | qualiow --version | — | Print the package version |

qualiow gather was removed in 2.0.0 — it was a stub that wrote nothing. Use the /qa-gather skill, which does the real work.

A global install also puts the mobile helpers on PATH: mcli, wadb, wk-ios, qualiow-doctor-mobile, qualiow-setup-mobile.

Token routing

Work with a fixed contract belongs to the CLI, not to the model. A session loads the knowledge base through qualiow kb digest instead of reading data/knowledge/manifest.yml and the five always-load entries (~964 lines) whole, and it ends with qualiow session finalize, so the INDEX and all-bugs.md rows and the metrics line are never hand-written; /qa-knowledge-list and /qa-explore-cleanup are wrappers around list knowledge and session …. The coverage level of a contract-2 session is computed the same way, by qualiow session level, and the report copies it verbatim.

Below the CLI sits a second tier, new in 2.2.0: bulk reads that need light judgement go to a cheap sub-agent that returns a bounded, cited digest rather than a whole file.

Everything that requires judgement stays where it is: severity, priority, business impact, the bug reports themselves, the charter and risk ranking, what is missing, the AC verdicts, the executive summary and the reflection. The one bounded exception is the bug judge (below): a second opinion on whether a candidate bug reproduces, from a context that never saw how it was found. The list of what is never delegated, and the read thresholds that route the rest, is skills/qa-explore/references/delegation-rules.md.

Sub-agents

Five sub-agents ship with the pack, in .claude/agents/ (mirrored to agents/). Each one works on the session's behalf and hands back a bounded result:

| Sub-agent | Model | Returns | Called by | |-----------|-------|---------|-----------| | qa-gather-agent | sonnet | the requirements context file, with [GAP] and [ASSUMPTION] markers where a source was silent | /qa-gather, which runs entirely inside it | | qa-reporting-agent | sonnet, effort: low | session-report.md assembled from the phase files and phase-7-notes.md, then qualiow session finalize; a summary of at most eight lines | the reporting phase of /qa-explore, /qa-explore-mobile and /qa-verify-backend, and /qa-explore-report | | qa-diff-indexer-agent | haiku, effort: low | a table of file → symbols or resources → line ranges → candidate AC ids, plus the files that map to no AC and the ACs that map to no file | the static-review phase of /qa-verify-backend, when the diff crosses the gate | | qa-page-mapper-agent | haiku, effort: low | a map of one raw snapshot: forms and their fields, navigation text → ref, interactive controls, visible error and empty-state text, hidden/disabled counts | the discovery phase of /qa-explore, for a snapshot too large to read | | qa-bug-judge | opus, effort: high | one fenced verdict on one claim card — CONFIRMED, CONFIRMED-ADJUSTED, REFUTED, UNREPRODUCIBLE or UNVERIFIED — with method, confidence, repro result and reasoning | the reporting phase of /qa-explore, once per candidate bug, unless verification is off |

Four of them never return a verdict. No severity, no priority, no business impact, no "this is a bug", no PASS/FAIL. They extract, index and assemble; the session decides. A delegate that volunteers a judgement has exceeded its brief and that part of its answer is discarded.

qa-bug-judge is the one bounded exception. It rules on two things only: whether the claim in a card reproduces or is carried by its evidence, and, as advice, whether the claimed severity fits the severity guide. Whether to ship, the final severity, the business impact and every word of the shipped report stay with the session, which may overrule a refutation it can disprove. See Bug verification.

Quick sessions write their own report — spinning up an agent costs more than it saves for a 15-minute session.

Advisory triage (opt-in)

Phase 7 of /qa-explore can also ask a decision model — one that returns typed probabilities about text, not prose — how a claim card looks before the judge runs, and record the answers next to the judge's verdict. It is off by default and strictly advisory: the judge still sees every claim, in the same order and with the same budget, never reads the triage files, and nothing ships or is skipped on the triage's say-so. A target opts in with:

verification:
  mode: triage-shadow            # judge (default) | off | triage-shadow
  triage_providers: [laya]       # laya (self-hosted, loopback only) and/or typesafe (hosted)
  # triage_api_key_env: TYPESAFE_API_KEY   # typesafe only; the value lives in qa/.env or .env

• laya — a self-hosted Laya server on /v1/systemone. Its endpoint must be loopback, checked before anything is sent, and redirects are refused, so nothing leaves the machine.
• typesafe — TypeSafe's hosted Jev. One scrubbed claim card per candidate bug leaves the machine; the exact request is saved as verification/JEV-NNN.json. The scrubbing is pattern-based and has gaps (IP addresses, single-label hosts, URL paths, free-text names), so read a --dry-run first.
• --provider only narrows the target's own list; it cannot add a provider the target did not name.

Each run writes verification/JEV-NNN.* or LAYA-NNN.*: a predicted verdict, a recorded reading (refute-risk, unclear, likely-confirmed), a severity fit and the evidence that was and was not sent. The predicted verdict is a guess at the judge's, never a verdict. Full reference: skills/qa-explore/references/evidence-triage.md.

Hooks

Three PreToolUse hooks enforce what the delegation and security rules ask for. The read and write guards are scoped to qualiow-owned paths; the bash guard sees every Bash command but only acts on the few patterns below, so ordinary coding in the same project is unaffected:

• read-guard.mjs (matcher Read) fires only for data/knowledge/manifest.yml, data/knowledge/releases/**, output/sessions/*/phase-*.md and output/sessions/*/snapshots/*. A whole-file read of one of those over QUALIOW_READ_MAX_LINES lines (default 300) is denied, with the cheaper route named in the reason — qualiow kb digest, qualiow list knowledge --entry <id>, a Grep plus a Read with offset/limit, or qa-page-mapper-agent. A Read that already carries offset or limit passes untouched.
• write-guard.mjs (matcher Write|Edit|MultiEdit|NotebookEdit) fires only for files under output/ and never inside snapshots/. It denies content matching the same redaction list the formatters and qualiow session finalize apply — for an Edit, the file as it will read after the edit — naming the categories it matched, so a secret is caught before it reaches disk rather than after.
• bash-guard.mjs (matcher Bash) asks before playwright-cli run-code (it runs in the Playwright node process, not the browser sandbox), asks before git with options that can run a shell (-c, --upload-pack, --ext-diff…), and denies npx -c and npx -y/-p of a package outside playwright-cli, @playwright/cli and qualiow-exploratory-testing. It is a safety net, not a sandbox.

Set QUALIOW_HOOKS=off to disable all three, and QUALIOW_READ_MAX_LINES to move the threshold — in .claude/settings.json under env:

{ "env": { "QUALIOW_HOOKS": "off", "QUALIOW_READ_MAX_LINES": "500" } }

Plugin installs get the hooks by default — hooks/hooks.json ships with the plugin and is discovered without any configuration. npm projects opt in with qualiow init --hooks, which copies the scripts to qa/hooks/ and merges into .claude/settings.json the three hook entries plus permissions.allow rules for Bash(playwright-cli:*), Bash(npx playwright-cli:*) and Bash(qualiow:*). The merge is by exact string, so running it twice changes nothing and hooks you already had are left alone. docs/GETTING-STARTED.md carries the same snippet for anyone who would rather write it by hand.

Do not enable both in one project. The plugin's hooks and the project's copies would both run — a harmless double deny, and two node processes per tool call for nothing.

Running sessions

Full session (45 minutes, 8 phases)

/qa-explore https://www.saucedemo.com/          # any public site
/qa-explore --target company-staging             # a saved target config
/qa-explore --target company-staging --context output/context/TICKET-123-context.md
/qa-explore --target company-staging --continue latest   # pick up what the last one deferred

Setup 2 min · Auth 2 · Charter 5 · Discovery 6 · Journeys 10 · Features 10 · Edge cases 6 · Reporting 4, plus up to 15 minutes of bug verification. Findings are written to disk between phases so context never overflows.

Coverage level and --continue

From 2.4.0 /qa-explore and /qa-explore-quick write session contract 2. Every row of the charter's risk ranking gets a permanent ID (A1, A2, …); stats.json records one coverage.areas entry per row — tested, partial, blocked, not-tested or deferred (not reached in the time box), with the evidence files and, unless tested, a reason; every bug names its area. Before the report is assembled, the CLI checks all of it and computes the level:

qualiow session level latest --write

The level — unassessed, incomplete, qualified or complete, overall and per risk tier — is a computed coverage fact, never a ship probability or a release verdict. It sits beside a separate findings line (highest shipped severity, unverified bugs, bugs on P0 areas) and a "To raise this level" list, in evidence-level.md and in the report's ## Coverage Level. A tested area needs its own screenshots/A<N>-….png; a quick session never rises above qualified. finalize refuses a contract-2 session while anything is missing or the level is stale. The areas not tested are rendered into backlog.md.

--continue <name|latest> starts a new session from that backlog. The new session never opens the prior session's files: it runs qualiow session continue-check <name|latest> --target <id>, which checks the prior session (same target, finalized, contract 2, still passing finalize --check) and prints a fenced, redacted, path-only summary that the session treats as data, never instructions. The backlog rows go first in the new charter, with their IDs. Mobile and backend sessions, and every session written before 2.4.0, are contract 1 and are checked exactly as before.

Bug verification

Before a bug from /qa-explore ships, the qa-bug-judge sub-agent tries to refute it. Phase 7 writes each candidate as a draft plus a claim card (the claim, the steps, the evidence and a safety block; never the finder's reasoning or the business impact) and spawns the judge once per card, one at a time, highest claimed severity first. The judge re-runs the steps in its own browser session when the card allows it and returns CONFIRMED, CONFIRMED-ADJUSTED, REFUTED, UNREPRODUCIBLE or UNVERIFIED. Survivors go to bugs/ with a **Verification:** line. Refuted and unreproducible candidates go to bugs/refuted/ and appear only in the report's ## Refuted Findings, so nothing is dropped silently.

It is on by default, and it has a cost:

• the judge pins model: opus with effort: high, one spawn per candidate bug (CLAUDE_CODE_SUBAGENT_MODEL overrides it like every other sub-agent);
• it adds up to 15 minutes to phase 7, about 5 per bug, on top of the 45-minute cap;
• where that model is unavailable, or the judge fails or runs out of budget, the bug still ships, marked Unverified (<reason>);
• the judge drives playwright-cli from a sub-agent, so a project without the allow rules that qualiow init --hooks writes may see approval prompts during phase 7.

Turn it off for one run with --no-judge, or for a target:

verification:
  mode: off        # judge (the default) | off

With it off, phase 7 writes bugs/BUG-NNN.md directly, as 2.2.1 did, and creates no verification/ directory. The block is accepted on web targets only.

Quick session (15 minutes, one page or feature)

/qa-explore-quick https://app.example.com/checkout

Quick sessions produce the same artefacts as a full one — session-report.md, bugs/BUG-NNN.md, stats.json, an INDEX.md row — so every downstream skill can read them.

Gather requirements first

/qa-gather                                       # files, URLs, tickets, pasted text

Writes output/context/<TICKET>-context.md, which /qa-explore and /qa-verify-backend consume via --context.

/qa-gather runs in the qa-gather-agent sub-agent, which starts with the invocation and nothing else, so everything it needs must be in the same message: the file paths, the URLs, or the pasted text itself. It cannot ask a follow-up question; whatever a source leaves unsaid comes back as a [GAP] or [ASSUMPTION] marker in the context file.

After a session

/qa-explore-report output/sessions/2026-09-08-1813-explore-parabank   # regenerate/reformat
/qa-explore-feedback                                                   # false positives, missed bugs
/qa-explore-cleanup                                                    # archive or delete old sessions
/qa-target-setup                                                       # configure a new target
/qa-knowledge-add                                                      # teach it a new heuristic
/qa-knowledge-list                                                     # browse the knowledge base

What a session leaves behind

Every session — web, quick, mobile or backend — lands in output/sessions/<YYYY-MM-DD-HHmm>-<kind>-<slug>/, where kind is explore, quick, mobile or backend:

output/sessions/2026-09-08-1813-explore-parabank/
  charter.md               # what is being tested and why
  session-log.md           # real-time findings with WHY reasoning
  phase-3-discovery.md     # phase artefacts (file number == phase number)
  phase-4-journeys.md
  phase-5-features.md
  phase-6-edge-cases.md
  bugs/BUG-001.md          # one bug = one report
  bugs/refuted/BUG-004.md  # a candidate the bug judge refuted (explore, judge on)
  verification/            # claim cards and verdicts (explore, judge on)
  screenshots/BUG-001.png
  screenshots/A1-login.png # per-area evidence (explore and quick)
  snapshots/               # raw page snapshots — working files, never part of the report
  videos/
  traces/                  # Playwright traces kept as evidence (explore)
  evidence/                # any other evidence file an area or bug cites
  session-report.md        # executive summary, coverage level, coverage map, recommendations
  evidence-level.md        # CLI-written coverage level (explore and quick)
  backlog.md               # CLI-rendered areas not tested (explore and quick)
  stats.json

Plus a row in output/sessions/INDEX.md (| Date | Kind | Target | Bugs | Duration | Status | Report |) and an entry in output/bugs/all-bugs.md — both written by qualiow session finalize, which validates the session first and refuses one with a missing confidentiality header or an unredacted secret, or — for a contract-2 session — a gap in its coverage record or a stale coverage level. Bug reports open with the two-line confidentiality blockquote and the headline # BUG-NNN: [Component] fails [Condition] causing [Impact].

Project-local configuration

/qa-target-setup writes qa/target.yml (project-local, one target per repo) or, with --shared, data/targets/<id>.yml. Resolution order is:

--target <name>  →  qa/target.yml  →  data/targets/_default.yml

Credentials come from qa/.env, falling back to .env. The env var names the shipped configs reference: QA_USER, QA_PASS, QA_TOKEN, QA_AWS_PROFILE, QA_AWS_REGION, QA_API_TOKEN, EXAMPLE_API_KEY. Never put a secret in a YAML file — reference it by variable name.

Mobile sessions

/qa-explore-mobile runs a full exploratory session on an iOS Simulator or Android Emulator — either a native app (the installed app is the system under test) or a web app in the real device browser (Simulator Safari / Emulator Chrome — the genuine engines, which Playwright cannot drive). The mode comes from the target config.

1. One-time machine setup

bin/setup-mobile.sh                       # both platforms
bin/setup-mobile.sh --android             # or --ios to scope
bin/setup-mobile.sh --yes --allow-curl-bash   # non-interactive, incl. the curl|bash installers

It installs everything scriptable — Maestro (pinned via MAESTRO_VERSION, default 2.10.0), JDK 17, Android cmdline-tools + platform-tools + a Google-Play system image, the standard AVD qa_pixel_api35, the qa-iphone simulator device, and ios-webkit-debug-proxy — and prints the two genuinely manual iOS steps (installing Xcode, downloading an iOS runtime).

2. Preflight

bin/doctor-mobile.sh          # or --ios / --android / --quiet

Read-only. Installs nothing; prints ✓/✗ with the exact fix command for each gap, and checks Node >= 22.4, python3, Maestro >= 2.6.0 and ios-webkit-debug-proxy.

3. Pick a target template

cp data/targets/_example-sim-ios-safari.yml data/targets/local-my-app.yml

| Template | What it tests | Driver | |----------|---------------|--------| | _example-native-mobile.yml | An installed iOS/Android app (native mode) | mobile-cli (Maestro) | | _example-sim-ios-safari.yml | A mobile web app in real iOS Simulator Safari | mobile-cli (Maestro) | | _example-sim-android-chrome.yml | A mobile web app in real Android Emulator Chrome | mobile-cli (Maestro) | | _example-mobile-emulation.yml | A mobile web app via Playwright device emulation (no simulator) | /qa-explore (playwright-cli) |

/qa-explore-mobile --target local-my-app     # real sim/emulator, native or web
/qa-explore --target local-my-emulation      # Playwright mobile emulation

4. Driving the device by hand

The skill runs bin/mcli (or qa/bin/mcli in an init'ed project, or mcli on PATH). Everything it does is available to you directly:

bin/mcli boot qa_pixel_api35                 # or an iOS sim name / UDID
bin/mcli --state /tmp/my-run.json set-device emulator-5554 --platform android
bin/mcli set-app com.android.chrome          # or com.apple.mobilesafari, or your app id
bin/mcli launch
bin/mcli open-url https://staging.m.example.com   # web mode (alias of deep-link)
bin/mcli snapshot                            # a11y tree as refs e1, e2, … (refs expire after 60 s)
bin/mcli fill e4 my-username                 # Maestro inputText
bin/mcli snapshot                            # ALWAYS re-snapshot after the keyboard appears
bin/mcli click e7
bin/mcli fill-id login-btn "pass"            # tap + type by testID, no snapshot needed
bin/mcli wait-text "Dashboard" 15
bin/mcli press HOME                          # BACK | ENTER | HOME | TAB | ESCAPE
bin/mcli screenshot evidence.png             # no app required
bin/mcli logs --errors --since 60            # logcat / simctl log; logs-clear on Android
bin/mcli record-start run.mp4 && bin/mcli record-stop   # mp4 on both platforms
bin/mcli info                                # resolved state + which state file is in use
bin/mcli --help

Exit codes: 0 ok · 1 command failed · 2 usage · 3 stale/unknown ref (re-run snapshot) · 4 no device or app set.

iOS Safari web targets also get real JS/DOM access through the WebKit bridge (needs ios-webkit-debug-proxy, python3 and Node >= 22.4; WK_IOS_PORT overrides the port):

bin/wk-ios 'document.title'
bin/wk-ios 'document.querySelectorAll(".cart_item").length'
bin/wk-ios --stop

Notes that save time:

• Never relaunch-clean a web target — it wipes the logged-in browser profile.
• SSO/MFA logins are done once, by hand, on the device. There is no transferable storage_state for a real device browser.
• bin/wadb is raw adb with ANDROID_HOME and JDK 17 resolved for you.
• Full guide and troubleshooting: docs/MOBILE-SETUP.md.

Backend, API and infrastructure verification

Not every acceptance criterion is visible in a browser. /qa-verify-backend covers tickets whose ACs live below the UI — tables and streams, queue consumers, Lambda triggers, IAM policies, webhooks, IaC, and the service's own HTTP endpoints — and produces an AC traceability matrix instead of a pass/fail claim.

cp data/targets/_example-backend.yml  data/targets/local-my-service.yml   # service behind a UI
cp data/targets/_example-api-only.yml data/targets/local-my-api.yml       # HTTP API, no UI

| Lane | What it does | |------|--------------| | Static | Reads the implementation branch against each AC with git show (never checks out) — spec drift, scope creep, failure paths, identity propagation, producer/consumer contract breaks | | Live | Read-only aws-cli probes, one per AC, raw output saved as evidence. Never mutates; hard stop on production | | API | Calls the service's own endpoints from the already-authenticated page, with a written case matrix covering everything the browser's guards prevent. Read-only, limited to the target's api.probe_allowlist | | End-to-end | Drives the real write path in a non-production environment, then re-probes the data layer — same-tick writes, deletes, bulk saves, a second identity, DLQ depth |

Each AC gets a verdict with cited evidence — PASS, PARTIAL, FAIL, BLOCKED, NOT-REACHABLE or UNVERIFIABLE — and the verdict names the mode it was reached by and the environment it holds in. PASS (direct request, raw response attached) and PASS (read the diff) are different claims, and a verdict backed only by a code reading is UNVERIFIABLE, never PASS. BLOCKED is a first-class outcome: when credentials are missing, the probe commands are written out ready to run rather than the verdict being inferred from source.

Two things it will not let you get away with

Believing a green result from an environment that does not run your code. Before the first probe, the skill fingerprints every component of the request path: which build is deployed, whether the changed path is selected here, and whether the commit under test is genuinely an ancestor of what is running. One identical build can hold two implementations of the same feature with a flag choosing between them — same build, different behaviour ⇒ configuration, not deploy lag. An environment that does not run the change gets NOT-REACHABLE.

Recording a client-side guard as the endpoint's behaviour. "The search box refuses to fire when empty" describes the browser. Every other client — mobile, partner integration, script — sends that request, and it is frequently the one that fails. When a ticket has both a screen and an endpoint, the same cases run at both surfaces and each finding is sorted into both, API only (a real defect the guard is hiding), UI only (the client invents or masks behaviour the service does not have) or neither.

The API lane needs no token handling: the request runs inside the page that is already logged in, so it carries the same session cookie, CSRF token and interceptors as the UI — which also means it works with SSO and MFA that no scripted login can pass. Credentials stay in the browser profile under .auth/ and never enter a script, a report or the repository. A service with no UI at all declares api.auth: api-key-env and the lane runs out of browser, reading the key from the environment variable the target names.

Correct shape is not a correct answer

Every derived value — a percentage, total, ratio, delta or aggregate — is recomputed from the raw figures in the same response, with the formula taken from the specification rather than from the code under test, and with cases chosen to stress sign, zero, scale and cardinality. Then the report states the limitation plainly: when both sides of the check come from one payload, the derivation is verified and the inputs are not, so the independent oracle that would close the gap is named along with whether it was run.

The payload is also held next to the screen, because a correct response can still reach the user as a wrong number — a formatter that guesses what a value is, a unit applied twice, a truncated figure presented as a total. That defect is invisible from either surface alone, and it usually belongs to a different change than the one under test.

Findings with no acceptance criterion become a spec

Most of what an API probe turns up has nothing to be filed against, so it turns into an argument rather than a fix. data/templates/expected-behaviour.md converts a pile of observations into one reviewable decision: observed against expected, grouped by cause, with the decisions the fix forces made explicit — reject rather than clamp, an error rather than a silent zero, validation at the layer that covers every implementation — ranked by what real users can reach today, and closed with a plain-English reply for whoever decides to fund the work.

Verifying a release rather than a ticket

skills/qa-verify-backend/references/release-readiness.md changes the shape of the session: the deployment table first for every ticket, so a ticket whose backend is not in the build is marked not testable here rather than tested against a UI that will render convincing nonsense; a result vocabulary that keeps not tested visible; a coverage map where 🔍 code-verified only is marked as UNVERIFIABLE rather than green, with one sentence naming the untested item that carries the most risk; carry-over defects in their own section; and a disposition with the condition that would reverse it.

Reports

qualiow report exports an existing session in four formats. Every export carries the confidentiality header and runs through the same redaction list as the skills.

qualiow report -s latest -f html -o report.html      # writes output/report.html
qualiow report -s 2026-09-08-1813-explore-parabank -f jira -o bugs.csv
qualiow report -s latest -f json --stdout

| Format | Output | |--------|--------| | md (default) | session-summary.md next to the session report — never overwrites it | | html | Self-contained dark-mode page: severity cards, bug details, coverage map, recommendations. Print-friendly, CSP-restricted, noindex | | json | Structured data for dashboards, CI and metrics tracking | | jira | CSV for Jira bulk import; severity maps to priority (Critical → Blocker, High → Critical, Medium → Major, Low → Minor) |

The same formatters are exported as a library:

import {
  generateHtmlReport,
  generateJsonReport,
  generateJiraExport,
} from 'qualiow-exploratory-testing';

const session = 'output/sessions/2026-09-08-1813-explore-parabank';

const html = await generateHtmlReport(session);
const json = await generateJsonReport(session);
const csv  = await generateJiraExport(session);

Skills

| Skill | Purpose | |-------|---------| | /qa-explore | Full exploratory testing session (45 min, 8 phases); --continue <name\|latest> starts from a finalized session's backlog | | /qa-explore-quick | Quick focused session on a single page or feature (15 min) | | /qa-explore-mobile | Session on a simulator/emulator — native apps or web in the real device browser | | /qa-verify-backend | Backend/API/infra AC verification — branch review, read-only cloud probes, API probes, traceability matrix | | /qa-gather | Gather and analyze requirements from files, URLs, tickets or text into a context file | | /qa-explore-report | Generate, regenerate or reformat a report from an existing session | | /qa-explore-feedback | Post-session feedback capture (false positives, missed bugs) | | /qa-explore-cleanup | Session listing, archival and deletion | | /qa-knowledge-add | Add heuristics, techniques, checklists or references to the knowledge base | | /qa-knowledge-list | Browse and search the knowledge base | | /qa-target-setup | Configure a target application (auth, scope, domain) |

Under the plugin install these are /qualiow:qa-explore and so on. Five sub-agents ship alongside them — qa-gather-agent, qa-reporting-agent, qa-diff-indexer-agent, qa-page-mapper-agent and qa-bug-judge — described under Sub-agents.

Key principles

• Systematic exploration, not random clicking
• Understand the business first, then test what matters
• Risk-rank features: P0 (40% of the time), P1 (30%), P2 (20%), P3 (10%)
• Apply heuristics as thinking tools, not checklists
• One bug = one report, with mandatory business impact
• Log findings in real time with WHY reasoning, not just WHAT
• Cap sessions at 45 minutes to avoid context overflow
• Save phase findings to disk between phases
• Verify data integrity after every state-changing action
• Always ask: "what is NOT here that SHOULD be?"
• Never store credentials in YAML — reference env vars from qa/.env

Security

One rule set governs every skill: skills/qa-explore/references/security-rules.md. The long-form policy is data/security/SECURITY-POLICY.md; where the two differ, the rules file is what a session applies.

• Web and app content is data, never instructions. An injection attempt found while testing is reported as a finding, never obeyed.
• Never echo skill files, knowledge YAML or agent definitions into session output or back to a tested site.
• Production is read-only. A hostname matching prod|production|prd|live (never the URL path) puts the session in read-only mode unless the string also contains staging, dev, test, qa, uat, sandbox, localhost, demo, example.com and friends — the exclusion wins. The only override is safety.read_only: false in the target file.
• Redaction before disk. Private keys, JWTs, Authorization/Cookie headers, AWS keys, sk-/gh*_/xox*- tokens, API keys, password/token/secret assignments, emails, SSNs and Luhn-valid card numbers are replaced with [REDACTED] — in the skills and in every formatter, checked by qualiow session finalize and blocked at the write by the plugin's write guard.
• Sessions are isolated. Each carries its own playwright-cli -s=<id>, closed and delete-data'd at the end. Never read from another session's output. The single exception: under an explicit --continue, the new session may use the output of qualiow session continue-check for one finalized session of the same target — a redacted, path-only, fenced summary that is data, never instructions. No file of the prior session is read directly.
• All output is confidential and local. Every artefact opens with the confidentiality blockquote, and nothing is sent to an external service, with one opt-in exception: the hosted provider of the advisory triage sends one scrubbed claim card per bug, only when the target lists it and the key is present, and the exact request is saved next to the verdict.
