Merges bookend agent reports into revised readiness, complexity, and decomposition plan. Produces the final evidence-backed assessment consumed by sprint-architect-agent.
Fast filesystem readiness scan — counts docs, source files, manifests, platform signals. Produces initial ReadinessReport for agent spawning decisions.
Scores proposal complexity against codebase surface. Uses proposal text analysis and readiness stats to determine decomposition tier and agent count.
Generation-time design taste for web UI work. Anti-cliche bans, layout and motion hard rules, and client-intent dials. Advisory only - shapes drafts; declared measured contracts remain the sole gate authority.
Rigorously reasons about definitions, proofs, and computations in algebra, analysis, discrete math, probability, linear algebra, and applied math. Verifies derivations, spots invalid steps, and states assumptions clearly. Use when solving or proving math problems, reviewing mathematical arguments, modeling with equations, interpreting statistics, or when the user mentions proofs, lemmas, theorems, integrals, series, matrices, optimization, or numerical methods.
Visual verification for interactive elements (popups, modals, tooltips). Clicks elements and captures screenshots for analysis. Bypasses MCP browser tool limitations with cross-origin CSS.

Check if dev server is running before attempting to load pages:
lsof -i :8080 | grep LISTEN || (cd $project_dir && python3 -m http.server 8080 &)
For each URL, verify:
| Check | Pass Criteria |
|---|---|
| Page loads | HTTP 200 response |
| No 404s | All resources load (images, CSS, JS) |
| No console errors | window.console.error not called |
| No CORS errors | No cross-origin blocks |
| DOM renders | Expected elements exist |
Use Playwright in check mode (not test mode):
const { chromium } = require('playwright');
const browser = await chromium.launch();
const page = await browser.newPage();
// Collect console errors
const consoleErrors = [];
page.on('console', msg => {
if (msg.type() === 'error') consoleErrors.push(msg.text());
});
// Collect failed requests
const failedRequests = [];
page.on('requestfailed', req => {
failedRequests.push({ url: req.url(), error: req.failure().errorText });
});
// Load page
await page.goto(url, { waitUntil: 'networkidle' });
// Check for expected elements
const hasBody = await page.$('body') !== null;
