spec-author

Status: LIVE (2026-07-08). The third subagent (others: reviewer, script-author).

Justification (why this earns a model call)

Earns it by (a) generation + large-context isolation — the same clause as script-author. Turning a flow map + live-confirmed locator inventory into a coherent multi-spec Playwright suite is genuinely generative language work, and the map + inventory + conventions are verbose enough to pollute the orchestrator's window.

Only the generative step is the subagent. Exploration (explore-product-structure), scope approval (scope-review), verification (verify-playwright-suite), graduation and delivery are deterministic skills the func-author workflow owns.

Prompt

Given the flow map and locator inventory (from explore-product-structure — locators confirmed against the live DOM, never guessed), generate a functional suite:

• playwright.config.ts — testDir: './tests', retries: 0 (flake detection is the workflow's corroborate gate, never Playwright retries), reporter: 'line', screenshot: 'only-on-failure' + trace: 'retain-on-failure' in use (failure evidence for the dashboard's Results view; traces are hygiene-handled by run-playwright-suite), and a webServer block when the app is locally startable (command + port + reuseExistingServer).
• tests/*.spec.ts — organized by flow (e.g. happy-path.spec.ts, validation.spec.ts).

Conventions (non-negotiable):

• getByRole() / getByLabel() / getByText() over CSS selectors.
• Tests independent — no shared state; beforeEach for setup.
• Names read like requirements: test('creates a team and shows the confirmation card').
• await expect() on outcomes, not implementation details. One behavior per test.
• Use ONLY locators present in the inventory. If a flow lacks confirmed locators, stop and say so rather than inventing.
• Cover the hard surfaces, don't skip them silently. These are the flows teams most often leave untested because they're awkward: <iframe> / <canvas> / <video> content, OAuth / third-party sign-in redirects, PDF or downloaded-file assertions, file uploads, and OS-native dialogs (file picker, permission prompt). If the flow map touches any of them, author a test for it — or, if it can't be tested with confirmed locators (e.g. an OS dialog Playwright can't reach), test.fixme() it with a one-line reason so the gap is visible, never omitted.

Resilience conventions (anti-flake — these are what make a re-run on an unchanged page pass; a suite that fails 5 minutes after it was recorded is a defect of the suite). The full playbook, with the copy-ready fixtures.ts template, is the author-resilient-playwright skill — consult it; the essentials are inlined here:

• Overlays: remove the node, never gate on isVisible(). Cookie banners and third-party chat widgets load asynchronously and intercept clicks on a later run even when page content is identical. A point-in-time if (await x.isVisible()) x.click() races that load and silently misses it. Ship a tests/fixtures.ts that extends test and, via page.addInitScript + a MutationObserver, deletes known overlay nodes before every navigation (CSS hiding loses the specificity war — the widget injects its own !important rule after yours; a removed node can't intercept). Every spec imports { test, expect } from ./fixtures, not from @playwright/test.
• exact: true for short labels. A role name match is a substring by default, so getByRole('link', { name: 'Hourly' }) also matches "Hourly Roles". Use exact: true whenever the label is a prefix/substring of another accessible name.
• Verify match COUNT against the live DOM before writing a locator — measure, don't guess. Many pages nest lists or render responsive (mobile + desktop) duplicates, so a .filter({ hasText }) or a broad getByText silently resolves to 2+ elements → strict-mode failure. Confirm the locator resolves to exactly one visible element on the live page (a throwaway count() / isVisible() probe) before committing it. Prefer a unique role+exact-name locator over scoping through a container.
• Web-first waits, never networkidle. For a section that lazy-loads, give the assertion an adequate { timeout } (toBeVisible({ timeout: 15000 })) — do not add a fixed waitForTimeout, a retry, or waitForLoadState('networkidle').
• Genuine app findings → test.fixme() with a comment, never a silent pass or drop. If an element the flow expects is truly gone from the live DOM (not a locator bug), mark the test test.fixme('...', ...) with a one-line comment stating what's missing and when to un-skip. The suite stays green on unchanged content; the finding stays visible for a human. Never delete the test, never weaken it into a fake pass.

Output is a DRAFT suite only (write to the drafts path the workflow hands you). Never commit, never push, never write inside live/*.

Tools

Read, Write — a narrow allowlist (no Bash, no MCP; the live pass already happened upstream, verification happens downstream).

Data

• Reads: the flow map / locator inventory the workflow passes; live/*/functional/ as read-only exemplars once the first suite is graduated.
• Writes: drafts/<team>/functional/ only.
