Govern evidence-backed canonical project state across sessions, branches, reviews, and research cycles. Maintains authoritative status, decisions, constraints, and negative evidence so any agent resuming work can verify claims, avoid repeated failures, and know the next step.

A governance skill designed to secure AI agent tool calls using advanced authorization policies. It implements Cedar policies to control which tools agents can access and under what conditions. Key features include running in 'Shadow mode' for safe observation, 'Enforce mode' for strict blocking, and generating cryptographically signed Ed25519 receipts to provide an immutable, tamper-evident audit trail for every policy decision.

Read every Architecture Decision Record (ADR) in a project before summarizing architectural context or decisions. Discover the actual ADR location, inventory all records, read each complete file, and report unread, missing, or inaccessible records explicitly. Preserve distinctions between proposals and accepted decisions.

Reference document for monopoly scale-benchmarks. Provides quick formulas for converting DAU to RPS, storage and bandwidth estimation, known scale limits of common technologies (databases, queues, caching), capacity planning by user scale (1K to 10M DAU), SLO targets, and latency budget guidelines. Useful for system design, capacity planning, and architecture decisions.

This skill helps design honest scarcity and urgency messaging based on verified inventory, capacity, or deadlines. It creates genuine psychological motivation without manipulation, ensuring trust is preserved. It involves audience research, ethical guardrails, and matching tone to cynicism levels to drive timely decisions effectively.

Designs email nurture and multi-touch sequences using commitment-pacing psychology: curiosity loops, reciprocity, gradual commitment, and one emotional job per message to build trust and prepare the next decision.

This skill covers essential principles for managing production servers, focusing on decision-making rather than memorizing commands. It includes process management, monitoring strategies, log handling, scaling decisions, health checks, and security best practices to ensure system stability and reliability.

Rewrites the last response to be simpler and shorter while preserving all key decisions, action items, and substance. Useful when the user requests a TLDR, a condensed version, or a compressed answer without losing important details.

This skill helps select and place genuine testimonials, case studies, and social proof to address specific trust barriers in marketing.

The analyst uses data-driven frameworks to deliver actionable insights for pre-seed through Series A companies, ensuring strategic decisions are grounded in realistic benchmarks and industry standards.

This skill provides a structured approach to systematically identify security threats by applying the STRIDE methodology (Spoofing, Tampering, Repudiation, Information Disclosure, Denial of Service, Elevation of Privilege). It is crucial for conducting thorough threat modeling sessions, analyzing system architectures, reviewing security design decisions, and creating robust security documentation for compliance and auditing purposes.

A comprehensive reference guide for selecting core infrastructure technologies including databases, caching, message queues, and API protocols. Helps architects and developers make informed decisions based on scale, consistency, and specific use cases to optimize system design.
