Template system for building, tagging, and distributing competitive battlecards.

Reporting framework for executive visibility into manufacturing pursuits.

Use to craft executive-ready value narratives and ROI/TCO stories for enterprise pursuits.

Operational template for building social content calendars with approvals and publishing workflows.

Toolkit for structuring hypotheses, variants, guardrails, and measurement plans.

Style and formatting rules for API/SDK documentation, samples, and tutorials.

Use when designing copy experiments to optimize hooks, offers, and CTAs.

Processes and guardrails for recruiting, scheduling, consent, and incentive fulfillment.

Render A2UI JSON as native Castella widgets. Parse A2UI messages, handle actions, progressive rendering, data binding, and connect to A2UI-enabled agents.

Use to compile visual inspiration, color palettes, and typography references for creative concepts.

Use when structuring payouts, tiers, and eligibility for referral programs.

Use to track pursuit risks, owners, mitigation steps, and escalation triggers.

Build chat interfaces and agent management UIs with Castella. Create chat components, display tool calls, manage multiple agents, and build agent hubs.

Use to enforce stage definitions, next-step requirements, and data completeness across the pipeline.

Create user-centered, accessible interface copy (microcopy) for digital products including buttons, labels, error messages, notifications, forms, onboarding, empty states, success messages, and help text. Use when writing or editing any text that appears in apps, websites, or software interfaces, designing conversational flows, establishing voice and tone guidelines, auditing product content for consistency and usability, reviewing UI strings, or improving existing interface copy. Applies UX writing best practices based on four quality standards — purposeful, concise, conversational, and clear. Includes accessibility guidelines, research-backed benchmarks (sentence length, comprehension rates, reading levels), expanded error patterns, tone adaptation frameworks, and comprehensive reference materials.

Template for designing onboarding journeys, milestones, and measurement plans.

Format code and keep style consistent using the repository’s canonical formatting/lint commands from `AGENTS.md`. Use after implementing changes or when formatting drift causes noisy diffs; keep formatting changes intentional and verified with build/tests.

Framework for recruiting, activating, and rewarding community champions.

Checklist covering accuracy, style, accessibility, and localization requirements for documentation releases.

Enable AI agents to introspect and control Castella UIs via MCP. Create MCP servers, expose UI resources, handle MCP tools, and use semantic IDs.
