Running Bug Review Board

Running the Bug Review Board (BRB) QA pass

This skill runs a real-user QA pass on an app and feeds the output

into a Bug Review Board: a folder of structured bug reports, per-pass

run reports, a self-contained HTML dashboard, and a final YES/NO sign-off

the team can act on. Engineering's tracker (Linear / GitHub / Jira /

Notion) syncs bi-directionally so QA and engineering stay in step.

It generalizes a battle-tested workflow that already shipped phase QA on

Mokuhoe — the techniques are repo-agnostic.

Why this exists

Most engineers test their own code. They confirm what they wrote works.

That misses the bugs real users hit first — stale state across

flows, mobile overflow, copy that lies, paths that 404 mid-onboarding,

race conditions between auth and routing.

This skill simulates a real user. The QA agent acts like a careful,

mildly unforgiving customer who does not read the source code.

Two workflows — Auto QA and Interactive BRB

The skill splits the work into two distinct modes that share artifacts

but run in separate sessions on purpose:

• Auto QA pass — the agent drives the app, runs scenarios, files

bugs, generates the HTML report, writes a verdict. Optimized for

thoroughness and speed.

• Interactive BRB — a *different* agent meets with the user to

triage open / in-progress / fixed bugs. Runs the bi-directional pull

first, applies pattern-based heuristics to surface duplicates and

clusters, walks each bug, flips statuses, syncs to the tracker,

regenerates HTML, writes minutes. Optimized for shared judgment.

Keep them separate. Running BRB inside an auto pass lets triage bias

contaminate discovery and confuses attribution. See

references/brb-interactive.md.

The trifecta — three hats, one pass

For every pass, wear all three hats:

• Product Manager. Confirm the build delivers the user-visible

promise documented in the product spec or phase doc. If it does not,

that is a product gap, not a bug — flag it in the run report.

• QA. Execute every scenario from a real user's perspective on the

primary supported viewport(s). Capture evidence (snapshot, console,

server data when relevant). Pass / Fail / Blocked.

• Engineer. Watch for invalidated assumptions: phase doc says "X

uses function Y" but Y was renamed; new client orchestration appeared

in a flow the docs say is server-driven; fields exist in UI that

aren't in the spec. Finding gaps is the point — don't reverse-

engineer the docs to match buggy behavior.

Do not fix product code unless the user explicitly asks. Test,

document, file bugs, hand off.

Discover the app first (or you'll write bad tests)

Before writing a single test, understand the intent of the app —

what the customer is hired to do with it. See

references/discovering-the-app.md

for the full investigation playbook. The short version:

• Read the product spec / README / landing page / pitch deck (in that

priority order) for what the app promises.

• Read the phase doc (or current sprint plan) for what was **just

built**.

• Read prior QA gates / checklists for what passed before — regressions

are your highest-value finds.

• Read the bug-reports index — open bugs are scenarios you must re-test

first.

• Detect the project type(s). A repo can ship more than one app —

a web + iOS monorepo is common — so **collect every surface whose

signals are present** instead of stopping at the first hit. Two

disambiguation rules resolve *overlapping signals inside a single

app*; they are not a reason to skip a genuinely separate surface:

• Electron / Tauri beats Web app for the same app. An Electron /

Tauri project (electron, @electron/, @tauri-apps/ in

package.json, or electron-builder.yml / tauri.conf.json) also

contains package.json and web framework deps, but those deps

belong to the desktop app — count it once as a desktop app, do

not also count it as a separate Web app.

• macOS vs iOS on a shared *.xcodeproj / *.xcworkspace. A bare

Xcode project is shared between the two, so don't classify on it

alone — require a platform-specific marker (below).

The surfaces, with the playbook each activates:

• Electron / Tauri desktop app → use

computer-use-playbook.md. (On

non-macOS hosts where Computer Use is unavailable, the playbook's

graceful-degradation table directs you to drive the app's dev-server

URL via browser-playbook.md

instead.)

• Web app (web framework deps without Electron / Tauri markers) → use

browser-playbook.md.

• iOS / iPadOS app (an iOS-specific marker is present — .iOS(...),

platform :ios, UIDeviceFamily, or an ios/ directory) → use

ios-simulator-playbook.md.

• Native macOS app (a macOS-specific marker is present — .macOS(...),

a .app bundle, or LSMinimumSystemVersion — and no iOS marker) → use

computer-use-playbook.md.

• Mixed (monorepo) — signals for two or more distinct surfaces

above (e.g. web framework deps and an iOS marker) → run every

matched playbook; the test plan gets per-platform scenario blocks.

A web match must never short-circuit a co-located iOS (or macOS)

pass.

• Other (no UI signals) → no UI playbook activates.

Also note whether Codex Computer Use is available (macOS only) —

it enables a human-fidelity pass on web apps and is the only way to

reach a native Mac or Electron/Tauri app. Most VMs (Cursor cloud, CI)

won't have it, so never make the pass depend on it.

• Detect the issue tracker (Linear, GitHub, Jira, Notion, or

none). Surface every signal found and ask the user to confirm

before writing qa-config.json. See

issue-trackers.md.

• List the public routes / surfaces / entry points and decide which a

real new user would touch.

If the user says "QA this app" but no docs exist, ask — see

references/discovering-the-app.md § Asking the user.

Workflow (any phase, any repo)

1. Scope        → which surface / phase / build
2. Discover     → product intent + recent change + open bugs
                + project type + issue tracker (confirmed)
3. Plan         → manual test plan (scenarios, IDs, expected, gates)
4. Prepare      → env, build, test accounts, viewport / device matrix
5. Mode         → parallel coordinator OR sequential wrap-up
6. Execute      → real-user scenarios with evidence
7. File bugs    → P0/P1/P2 with reproduction steps
8. Merge        → results + verdict (YES/NO + open P0/P1)
9. Generate HTML → apply html-report-style-guide.md
10. Hand off    → next QA agent (if NO) or engineering (if blockers)
11. Schedule BRB → separate session for interactive triage

Surfaces — which playbook activates

Detected during the discovery step. Match repo signals to the

playbook(s) for every surface present — usually one, but a monorepo

matches more than one (see Mixed below). Record the choice(s) in

docs/qa/qa-config.json so later passes don't re-litigate it.

| Surface | Signals | Playbook |

|---------|---------|----------|

| Electron / Tauri desktop app *(check first — beats Web app)* | electron, @electron/, or @tauri-apps/ in package.json; electron-builder.yml; tauri.conf.json | computer-use-playbook.md |

| Web app | package.json with web framework deps (no Electron / Tauri markers), app/ / pages/ / src/routes/, deploy config for Vercel / Netlify / Cloudflare | browser-playbook.md (add Computer Use for a human-fidelity pass on a Mac) |

| iOS / iPadOS app | Package.swift with .iOS(...), Podfile with platform :ios, Info.plist with UIDeviceFamily, ios/ directory (bare *.xcodeproj / *.xcworkspace are shared with macOS — require at least one of these iOS-specific markers) | ios-simulator-playbook.md |

| Native macOS app | Package.swift with .macOS(...), a .app bundle, Info.plist with LSMinimumSystemVersion | computer-use-playbook.md |

| Mixed (monorepo) | Signals for two or more distinct surfaces above (e.g. web + iOS) — a web match must not short-circuit the iOS / macOS pass | Run every matched playbook — the test plan gets per-platform scenario blocks |

| CLI / library / backend | No UI signals | Neither UI playbook; QA focuses on integration tests + error paths |

For iOS app QA, our skill orchestrates (discovery, test plan, bug

filing, BRB) and defers the simulator driving to one of the

iOS community's purpose-built skills — AXe (Cameron Cooke),

XcodeBuildMCP (Cameron Cooke / Sentry), ios-simulator-skill (Conor

Luddy), ios-build-verify (Josh Adams), baguette (tddworks),

ios-idb-skill (Hao Wu), serve-sim-skill (malopezr7),

swiftui-autotest-skill (Yusuf Karan), xcode-build-skill (pzep1), and

App Store Connect CLI + skills (Rudrank Riyam) for the TestFlight

hand-off. See the playbook for the recommended-stack table.

Issue tracker integration

The skill discovers and confirms — it never assumes. The

discovery ceremony probes signals

(LINEAR_API_KEY, gh auth status, Atlassian URL, registered MCP

servers, etc.) and surfaces every finding to the user before writing

docs/qa/qa-config.json. Once confirmed, the agent files bugs

locally and syncs to the tracker (push at file time or BRB time per

config) and pulls engineering's status changes back (default ON for

BRB start). Bi-directional reconciliation rules are spelled out in the

reference so divergences surface as user-decision diffs, never silent

overwrites.

Tracker IDs live in the bug front-matter — Tracker / Linear,

Tracker / GitHub, Tracker / Jira, Tracker / Notion,

Tracker / lastSyncedAt. The HTML report renders them as tags on

every bug card.

Helpers:

scripts/bugs-needing-sync.sh lists

bugs missing tracker IDs (push candidates).

scripts/bugs-needing-pull.sh lists

bugs whose Tracker / lastSyncedAt is stale (pull candidates).

HTML report (Zite + Dieter Rams)

At the end of every pass and every BRB session, regenerate

docs/qa/report/index.html plus per-bug and per-run detail pages by

applying html-report-style-guide.md.

The report reads like a magazine, not a Kanban board. Typography does

the work — priority is the word P0 in small caps, status is the word

Open, verdict is a single display-type word (YES or NO). One ink

colour for body, one quiet terracotta accent for links and CTAs,

hairline rules for separation. No coloured chips, no pills, no

shadows. A 640px reading column on every screen size; on desktop, bug

detail pages add a quiet right rail for metadata. On mobile, a sticky

thumb-zone duplicates the primary action so the reader doesn't have

to scroll back up.

The information hierarchy is engineered for the engineer-reviewer's

sweep: **Title → Deck → Impact → Actual / Expected → Risk to fix →

Steps → Evidence**. The bug template grew Impact and Risk to fix

sections in v0.3 (additive — old bugs render gracefully without them).

Markdown stays the source of truth. HTML is read-only and

regenerated. Never edit the HTML to change bug state — edit the

markdown and regenerate. The dashboard is what stakeholders open

during BRB and ship reviews.

Pattern-based triage suggestions

The Interactive BRB opens with a Suggestions card surfaced by a

catalog of named heuristics in

triage-heuristics.md — same suspect

file, steps-prefix overlap, same console error, same persona+surface+

outcome, phase cascade, cosmetic cluster, regression marker, same

owner. Every suggestion cites a heuristic name and the matching text

so the user always sees *why* something was flagged. No embeddings, no

LLM API, no auto-merge. The agent suggests; the user decides.

The same heuristics are also opt-in during the auto pass at file time

(triage.runHeuristicsOnFile, default false) so the pass can ask

"file new, or update BUG-007?" instead of double-filing.

Scaffold folders if missing

If the target repo has no QA folder structure yet, run the bundled

scaffolder to create it:

bash <skill>/scripts/scaffold-qa.sh "$REPO_ROOT" PHASE_NUM [SLUG]

It creates (idempotent — won't overwrite existing files):

<repo>/docs/qa/
├── README.md                         # how QA works in this repo
├── qa-config.json                    # stub; discovery rewrites once user confirms
├── phase-NN-<slug>-manual-test-plan.md  # filled-in skeleton (if PHASE_NUM given)
├── report/                           # HTML report destination (agent generates)
├── bug-reports/
│   ├── README.md                     # index + status workflow
│   ├── _template.md                  # bug template
│   └── assets/                       # screenshots (incl. ios/ for iOS QA)
└── runs/                             # per-shard + coordinator merges + BRB minutes

If a different layout already exists in the repo (e.g. tests/manual/,

qa/, an issue tracker), adopt that layout — do not duplicate it.

Always

• Real user perspective. Drive the app, not the source. Test from

URLs and clicks (or simulator taps), not from convex/users.ts or

the API layer alone.

• Test mobile, tablet, and desktop. Real users arrive on all three,

and layout / overflow / tap-target bugs hide at the breakpoint you skip.

Cover all three modes for web apps — reference sizes **mobile 375 × 812,

tablet 768 × 1024, desktop 1280 × 800** (adjust to the spec's

breakpoints). Lead with the app's primary target: take it from the

product spec; if the spec is unclear, ask the user which mode matters

most; if the user isn't available, infer the most likely primary from

what you discovered in the repo (responsive CSS / breakpoints, framework

defaults, marketing copy) and note the assumption. Record the modes and

the chosen primary in qa-config.json#platforms.web so later passes

don't re-litigate it. For iOS apps, the device matrix comes from

qa-config.json#platforms.ios.devices.

• One browser tab per agent. Parallel agents on a shared tab cause

auth-provider rate limits and stale sessions.

• Capture evidence. Snapshot or screenshot at the moment of failure,

console errors verbatim, server data row when relevant.

• File bugs immediately on FAIL — see

references/bug-filing.md. Do not wait

until end of pass.

• Use the test account playbook. See

references/test-accounts.md. If none

documented, ask the user before guessing.

• Session hygiene between scenarios. See

references/session-hygiene.md. Stale

storage / cookies / +test email reuse silently poisons fresh-user

flows.

• Run the discovery ceremony in

issue-trackers.md once per repo

before filing bugs.

• Regenerate the HTML report at the end of every pass and every BRB

session per html-report-style-guide.md.

• For iOS app QA, defer the actual simulator driving to a companion

skill from ios-simulator-playbook.md;

do not reinvent boot / tap / screenshot.

Never

• Mark a scenario PASS from code inspection alone. The user does not

experience source — they experience the app.

• Mark a phase gate ☑ without evidence (snapshot, server row, console

clean).

• Fix product code unprompted. Document. File. Hand off.
• Skip the Known issues / deferrals section in the phase doc —

those drive your scope and prevent false bugs.

• Rename phase docs or specs to match buggy behavior. Hides regressions.
• Run multiple QA browser sub-agents on one cursor-ide-browser tab.
• Reuse a previously-failed test email without changing the run-tag

suffix.

• Assume an issue tracker without asking the user — even when

signals are obvious.

• Run Interactive BRB in the same session as an auto QA pass —

they are intentionally separate to keep triage bias out of discovery.

• Auto-import tracker-only bugs into local markdown without asking

the user (default pull.createLocalForUntracked: "ask").

• Auto-merge bugs the heuristics flag as duplicates — every

merge / dedup needs user confirmation.

• Edit the HTML to change bug state. Edit the markdown; regenerate.
• Use the iOS simulator playbook for web-app QA. It's for iOS app

projects only. Mobile web QA stays in the browser playbook.

Bug priority (BRB taxonomy)

| Level | Definition | Action |

|-------|------------|--------|

| P0 | Blocks core flow; data loss; auth bypass; security | Phase cannot ship; halt QA pass until triaged |

| P1 | Feature broken or wrong; workaround exists | Blocks current phase sign-off |

| P2 | Cosmetic, edge case, accessibility, dev console noise | Defer to polish phase or release hardening |

When in doubt between P0 and P1, choose P0 if a user could land in

a non-recoverable state or lose data.

Pass criteria (any phase)

• All scenarios in the phase manual test plan PASS (or are

explicitly deferred with reason in the phase doc).

• Phase gate / checklist all green.
• No open P0 or P1 bugs against this phase.
• For phases that touch auth / invites / notifications: the regression

matrix is green.

Definition of done

Every pass ends with a coordinator merge doc whose top line reads:

> Phase N ready? YES — all gates ☑, no open P0/P1.

> Phase N ready? NO — list open P0/P1 + remaining unrun scenarios

> + a one-paragraph handoff prompt for the next QA agent.

If NO, the merge doc must be paste-ready into a new conversation.

The next agent should not need to rediscover state. See

references/gate-merge.md.

The HTML report (docs/qa/report/index.html) is also regenerated and

committed.

Browser tools (cursor-first, fallback ladder)

Default to cursor-ide-browser MCP when running inside Cursor. If

the session is in another tool or browser MCP is missing, fall back per

the ladder in references/browser-playbook.md:

• cursor-ide-browser MCP (Cursor / Claude Code)
• Chrome DevTools for agents (chrome-devtools-mcp) — auto-waits for

results and adds DevTools-grade network / console / Lighthouse / a11y

inspection; can attach to your real signed-in Chrome so auth flows

don't get bot-flagged

• browser-use MCP (provider-agnostic)
• Playwright (CLI or MCP)
• Codex Computer Use (macOS) — human-fidelity pass on the real signed-in

app; see computer-use-playbook.md

• Driving manually + asking user to paste console errors / screenshots

Whatever tool, the playbook is the same: navigate → snapshot → act

on fresh refs → capture evidence → unlock when done. The reference

covers each tool's specifics, including how to drive like a human so the

app doesn't trip on bot detection or timing races. The pass must succeed

with whatever the environment has — don't depend on Computer Use, which

most VMs lack.

Deliverables per pass

| Path | What |

|------|------|

| docs/qa/qa-config.json | Tracker + triage + report + platforms config (discovery rewrites the stub) |

| docs/qa/phase-NN-<slug>-manual-test-plan.md | (if newly generated) |

| docs/qa/runs/QA-<shard>-run-YYYY-MM-DD.md | Per-shard results |

| docs/qa/runs/COORDINATOR-MERGE-YYYY-MM-DD.md | Merge + verdict |

| docs/qa/runs/BRB-YYYY-MM-DD.md | (Interactive BRB only) session minutes |

| docs/qa/bug-reports/BUG-NNN-*.md + assets/BUG-NNN/ | Each defect |

| docs/qa/report/index.html + bugs/ + runs/ + assets.css | Apple-language HTML dashboard |

| docs/QA_GATES.md (or your repo's equivalent) | Gate boxes updated |

| Phase doc § QA status | Sign-off note + link to merge |

| Tracker issues (Linear / GitHub / …) | If syncOnFile or after BRB |

Adapt paths to whatever the target repo already uses.

• scripts/bugs-needing-sync.sh REPO_ROOT [--tracker …] — lists bugs

missing a tracker ID; the agent reads the list and pushes per

issue-trackers.md.

• scripts/bugs-needing-pull.sh REPO_ROOT [--threshold 24h] [--tracker …]

— lists bugs whose Tracker / lastSyncedAt is stale; the agent reads

the list and pulls per issue-trackers.md.

Extending this skill

Adding a new issue tracker, triage heuristic, surface playbook, or mode

is additive — copy a section, fill it in, the agent picks it up on the

next session. Forward-compatible qa-config.json schema (version: 1,

unknown fields ignored), additive bug front-matter, versioned HTML

report marker. See

references/extending-the-skill.md.

Anti-patterns to avoid

| Don't | Why |

|-------|-----|

| Mark scenarios PASS from code inspection | Users don't experience source |

| Defer P0 bugs to "next phase" | Foundation bugs cascade everywhere |

| Trust prior PASS marks without re-running on a fresh build | Regressions appear from unrelated work |

| Run multiple QA agents on one browser tab | Auth providers throttle; sessions bleed |

| Edit the phase doc to match buggy behavior | Hides the regression — file a bug instead |

| File a bug without Steps to reproduce | Engineering can't act on it |

| Test only the happy path | The happy path is what engineers tested already |

| Run BRB and an auto pass in the same session | Triage bias contaminates discovery |

| Sync bugs to a tracker without filling qa-config.json | Duplicates and lost edits |

| Use the iOS playbook to test a web app on Mobile Safari | Out of scope; the iOS playbook is for iOS app projects only |

| Auto-merge heuristic suggestions | Every dedup needs user confirm |

| Auto-import tracker-only bugs as local markdown | Engineering may have filed them in a context QA shouldn't claim |

| Edit the HTML to change bug state | Markdown is the source of truth; regenerate the HTML |

When a QA pass reveals work bigger than QA

If during the pass you find:

• A missing feature the phase claims exists (no code path at all)
• A schema diverging from the spec across multiple scenarios
• A P0 blocking every remaining scenario

Stop testing. Surface the finding. The user decides whether to escalate

to engineering or carve a smaller phase. Continuing wastes time on a

foundation that needs replacing.
