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.

|---|---|---|
layout_diff | View frame/bounds changed | Auto Layout changes |

Any test failed?
YES → Check diff_percent
> 5% → status: "fail", next_action: "fix"
1-5% → status: "warning", manual review
< 1% → likely rendering variance, pass
Record mode requested?
YES → Update reference snapshots
Basic snapshot test:
{
"project_dir": "/projects/MyiOSApp",
"ticket_id": "TICKET-IOS-001"
}
Record new baselines:
{
"project_dir": "/projects/MyiOSApp",
"ticket_id": "TICKET-IOS-001",
"record_mode": true
}
