Route web-game auto-playtesting with WAI Play (waiterve/wai-play): decide whether the next move is a testability check, authoring or repairing the `GameFlowAgentAPI` bridge, running a real browser playtest, reading the five-dimension quality report, or unblocking a key node the agent cannot reach. Use when the user wants an AI agent to actually play their HTML5 / canvas / vibe-coded web game and return reproducible evidence, scores, and fix suggestions across the five supported types (survivor-like, arcade shooter, platformer, puzzle/card, visual novel). Triggers on: wai-play, WAI Play, auto-playtest, AI plays my game, web game testing agent, GameFlowAgentAPI, GameFlowIntegration, jumpToScenario, game quality score, playtest evidence. Route Unity/Unreal frame-time work to `game-performance-profiler`, engine build failures to `game-build-log-triage`, human playtest notes to `game-demo-feedback-triage`, and generic browser automation to `browser-harness`.

Python 3.12 recommended. Runs locally as a Streamlit app with Playwright Chromium (`streamlit`, `playwright`, `openai`, `python-dotenv`). DeepSeek (planner) and Kimi (reporter) API keys are optional but degrade source modeling, route planning, and natural-language suggestions when absent. The upstream UI and reports are Chinese-language. Docker image available.
WAI Play drives a real browser against a running web game, models the game's
goal and key nodes, plays it, and returns a five-dimension quality score with
reproducible problem cards (state deltas, screenshots, โค20 s clips) and fix
suggestions. Test credibility is reported separately from game quality, so
a weak harness never inflates or deflates the game's score.
The work almost never starts at "run the test". It starts at can this game
be tested at all, and that answer decides everything downstream.
When to use this skill
A vibe-coded web game needs an automated play-through before a demo, jam
deadline, or release, and the user wants evidence rather than vibes
The game has no agent-readable state and needs a GameFlowAgentAPI bridge
authored or repaired
A test run finished and the user needs help reading the score, the problem
cards, or the credibility diagnostics
A required key node (first upgrade, boss phase, level goal, ending) cannot
be reached and the user must choose between repairing preconditions,
jumping, or taking the natural route
The user is deciding between local, Docker, and keyless (degraded) operation

Instructions
Step 1: Capture the intake packet before touching the tool
Collect five facts. Missing any of them changes the recommendation:
Game type โ one of survivor_like, arcade_shooter, platformer,
puzzle_card, visual_novel. WAI Play supports these five and nothing
else; a game outside them gets the closest profile plus a stated caveat.
Reachable URL โ the running game, not a repo. Localhost is fine.
Integration state โ does the page expose window.GameFlowAgentAPI?
URL-only black-box testing works, but flow modeling and key-node routing
are markedly weaker without it.
Source availability โ an optional ZIP matching the deployed version.
It is analyzed as a temporary copy only; WAI Play never edits the project.
Key availability โ DeepSeek and Kimi keys, or the honest keyless path.
Step 2: Pick exactly one mode
Mode
Use when
Produces
testability
Unknown whether the game can be driven at all
A go / no-go readiness note naming each blocking capability
integration
No API, or the bridge is a stub
A GameFlowIntegration bridge wired to real game state
run
The game is testable and configured
A configured run: type, URL, optional ZIP, step budget
report
A run finished
Score reading that separates game quality from test credibility
scenario-gap
A required key node is unreachable
Repair-plan / jump / natural-route decision with a reason
ops
Deployment, privacy, or keyless questions
Local vs Docker vs degraded operating choice
Do not blend modes. testability before run is the single highest-value
ordering in this skill โ a run against an unreadable game produces confident
nonsense.
Step 3: Check readiness with the read-only doctor
bash .agent-skills/wai-play/scripts/wai-play.sh doctor
bash .agent-skills/wai-play/scripts/wai-play.sh doctor /path/to/wai-play
doctor reports Python version, the four runtime packages, whether a
Playwright Chromium build is present, and which .env keys are set โ by
name only, never by value. It installs nothing and starts no test.
Step 4: Author or repair the bridge before blaming the game
The upstream v2 template refuses to fabricate state: an unimplemented
observe() or step() throws instead of returning plausible-looking data.
That is deliberate. A bridge that returns invented state produces a score
describing the bridge, not the game.
Statically check a candidate integration file before shipping it:
The checker is stdlib-only and prints one ```review fenced JSON block
listing missing methods, leftover template placeholders, unimplemented
throw-stubs, and required state fields it could not find. It exits 1 when a
blocker is present. It is a static text check: passing it means the file
looks contract-shaped, never that the bridge is wired to real game logic.
Confirm that separately.
This starts a local static server in the foreground โ a deliberate,
user-visible action, not something to run as a background side effect.
Step 6: Read the report with quality and credibility kept apart
Five weighted dimensions score the game: core flow (0.24), gameplay
(0.26), UI/visual (0.20), feedback (0.15), technical stability (0.15).
API integration completeness, evidence completeness, and agent reliability
are reported as credibility diagnostics and are excluded from those scores.
Two rules that are easy to get wrong:
The feedback dimension scores only what a player can see or hear, or
what a reviewer can confirm from the clip. An internal API value changing
is not on its own evidence of good feedback.
A single problem appears once, bound to the best attempt's evidence. Do not
re-report the same defect per occurrence.
When a required scenario cannot be entered, the API returns a coded reason,
and each code has one correct response:
Code
Meaning
Correct response
SCENARIO_PRECONDITION_MISSING
Judgement state is unreadable
Add the missing fields to observe(), then re-check
SCENARIO_LOADER_NOT_IMPLEMENTED
No scenario initializer exists
Implement it, or take the natural route
SCENARIO_UNSAFE_TO_JUMP
Jumping would leave state incoherent
Natural route; do not force a partial jump
SERVER_AUTHORITATIVE_STATE
Server owns the state
Request a test account, save, or injection endpoint
REPAIRER_NOT_IMPLEMENTED
No safe repair path
Natural route
Never satisfy a key node by setting one field. Upstream calls this out
directly: writing elapsed = 360 to reach a boss phase without initializing
level, gear, map, spawn pool, and boss AI produces a scenario that passes and
means nothing.
Test only games and source you own or are authorized to test.
Uploaded ZIPs are analyzed as temporary copies; clean them up after a run.
With AI source modeling on, source summaries are sent to the configured
third-party model providers (DeepSeek, Kimi). Say so before enabling it on
unreleased or client-owned code.
The current version targets local use. Public multi-user hosting needs
accounts, a job queue, quotas, remote-URL restrictions, and automatic test
data cleanup that upstream has not built yet โ say this plainly rather than
implying it is deploy-ready.
Testability before test. A run against an unreadable game yields a
confident, wrong report.
Never fabricate state in the bridge. A stub that returns invented data
scores the stub. Throwing is the correct unimplemented behavior.
Keep game quality and test credibility separate in every summary, the
way the tool does.
Initialize whole scenarios, not single fields. Partial jumps produce
passing key nodes with no meaning.
Prefer the natural route over an unsafe jump. A slower honest path
beats a fast incoherent one.
Bind every problem to one best-attempt evidence set โ state delta plus
screenshot or a โค20 s clip โ and report it once.
Say when a result is degraded. No keys means no source modeling, no AI
route planning, and rule-level suggestions only.
Name the five-type limit up front when the game does not fit one.
Examples
Example 1: "Can WAI Play even test my game?"
Run doctor, then check whether the page mounts GameFlowAgentAPI. If it
does not, the answer is black-box-only testing plus an integration mode
recommendation โ not a run.
Example 2: A bridge exists but every score is suspiciously low
