A busy shared browser slot returns `incomplete/browser_slot_busy`; retry after its owner finishes. It finds an installed `playwright-cli` in the root, `webui/`, or `packages/admin/`, then PATH. `PLAYWRIGHT_CLI_BIN` can select an existing executable; relative paths resolve from the invocation directory before the session changes directories. It never invokes `npx` or bypasses the lock. `--baseline` requires `--live`; the incomplete result rejects that flag combination when execution was not explicitly enabled. + +This illustrative plan must be adapted to controls actually observed on the target page: + +```json +{ + "version": 1, + "url": "http://127.0.0.1:4173/", + "goal": "Open Settings, select Dark, then close Settings.", + "actions": [ + { "id": "open", "op": "click", "role": "button", "name": "Settings" }, + { + "id": "theme", + "op": "select", + "role": "combobox", + "name": "Theme", + "value": "Dark", + "within": { "role": "dialog", "name": "Settings" } + }, + { + "id": "close", + "op": "click", + "role": "button", + "name": "Close", + "within": { "role": "dialog", "name": "Settings" } + } + ], + "requiredActions": ["open", "theme", "close"], + "assertions": [ + { "type": "bodyClass", "value": "dark", "present": true }, + { "type": "role", "role": "dialog", "name": "Settings", "state": "hidden" } + ], + "reloadBeforeFinal": true, + "limits": { + "maxSteps": 8, + "deadlineMs": 120000, + "maxSnapshotBytes": 40000, + "maxCostUsd": 0.01, + "minProbability": 0.8 + } +} +``` + +- Actions support `click` (button/link/tab/menuitem), `fill` (textbox/searchbox), `select` (combobox by exact option label), `check`, and `uncheck`. Values come only from the plan. Each action runs at most once unless `maxUses` explicitly allows up to three attempts. `nth` is a zero-based index for an intentionally duplicated role/name; otherwise duplicates are unavailable. `within` restricts a target to an exact named role. +- `requiredActions` must be present; use `[]` only when no action is required. Completion always requires every exact assertion, regardless of what the model predicts. Assertions support full URL equality; a body class present/absent; and a role's `visible`, `hidden`, `checked`, `unchecked`, `value`, or exact `text` state. Value/text assertions use `equals`. +- `reloadBeforeFinal` proves those assertions again after reload. It is useful for persistence checks; it should be off for deliberately transient states. +- `allowRemote: true` explicitly permits an HTTPS non-local starting URL. All subsequent top-level navigation stays on that exact origin. Popups are closed; service workers are blocked. This is a scope guard, not a network sandbox: applications can still make their normal requests. +- Common login/publication/payment/destructive labels are blocked unless the plan explicitly sets `allowSensitiveActions: true`. Label matching is not proof of safety: inspect the allowlist and expected effects yourself. Do not use real credentials, public posting, or payment flows without task authorization. +- Plan/schema errors, absent/ambiguous controls, uncertain choices, API failures, step/time/budget limits, assertion failures, and cleanup failures return `incomplete`. If a selected control disappears or its ref changes during a decision, the helper discards that decision and makes up to two fresh plans within the existing step/request/time budgets. Continued target churn returns `incomplete/stale_target`; stale actions are never executed. Unsupported snapshot serialization is unavailable, never guessed. The coding agent can inspect the page and continue with ordinary Playwright. + +Each decision uses a fresh snapshot, only currently observed approved controls, a strictly validated typed response, and a pinned returned model. After Jev answers, the helper refreshes the snapshot again and checks the same ref; fixed Playwright code checks the exact role/name locator, element identity, visibility, enabled state, and origin immediately before acting. The model cannot supply JavaScript, selectors, shell commands, arbitrary URLs, or a passing result. + +JSON stdout includes a bounded, key-redacted plan path relative to the invocation directory, status, action IDs, exact assertion booleans, advisory results, the `staleReplans` count, elapsed time, and sanitized usage totals. Exit `0` means offline validation succeeded or the exact assertions and all requested semantic checks were satisfied; exit `2` means incomplete/invalid or semantic review is needed. A wrapper warning that its browser close failed returns `incomplete/cleanup_failed`, even when the wrapper exits zero. The plan reference distinguishes route-specific runs without repeating full URLs that may contain query or hash secrets. Private temporary browser output is removed during cleanup. A failed close or forced termination can leave the owned session behind; identify the exact session through the shared wrapper before cleanup. + +## Semantic text checks + +Optionally add checks to a browser plan: + +```json +{ + "semanticChecks": [ + { + "id": "posting_error_help", + "role": "alert", + "name": "", + "criterion": "Explains why this attempted operation failed and gives an actionable next step." + } + ] +} +``` + +After exact completion assertions pass, the helper freshly reads text from that unique visible target and asks one narrow question. Results are `satisfies`, `issue`, `uncertain`, or `unavailable`, always advisory. An issue, uncertainty, or unavailable answer requires human/agent review: the overall result is `incomplete`/exit `2`, with `flowCompleted: true` preserving the separate exact completion evidence. Baseline runs report `not_run`, require review for those requested checks, and make no Jev calls. Semantic checks cannot validate layout/screenshots, diagnose wasted React renders, or overrule a failed deterministic assertion. + +Use only task-approved test content: relevant page text is sent to TypeSafe. The helper does not use personal profiles or persist prompts, raw model responses, or page snapshots in its final report. A full snapshot may contain peer content; keep fixtures/public test data small and intentionally scoped. + +## Budgets and evidence + +The shared client enforces request count, per-request UTF-8 bytes, a cumulative conservative input-token reservation, spend reservation, and time limits. It never retries automatically. Failed calls consume reservation too. Cost estimates use $0.042 per million input tokens and free output, the documented rate when introduced; confirm current provider pricing before treating estimates as bills. `usageMissing` counts requests with unknown billed input, including errors; when nonzero, `estimatedCostUsd` is `null` and `knownCostSubtotalUsd` is only the known subtotal. Actual metered tokens and the conservative reservation are reported separately; the latter is not a billing guarantee. + +The default browser bounds are eight actions, 120 seconds, 40 KB snapshots, a $0.01 reservation, and a minimum selected-choice probability of 0.8. This probability is a routing threshold, not a calibrated probability that the test is correct. A pinned model is chosen through runtime environment/arguments so upgrades remain intentional. + +Compare the same plan in baseline and Jev modes, across multiple representative flows. Count full-loop time, incomplete runs, cleanup, and API usage as well as model latency. Jev only accelerates the agent's decision layer; an already deterministic Playwright script is often faster and should stay deterministic.
