## What system-architecture-capture does, in the publisher's words

The second brain for system architecture information.

SAC is the specialized second brain for this class of knowledge: reverse-engineered services, packages, APIs, IaC, containers, serverless, CI/CD, networking, IAM, identity, ownership, and architectural context from monorepos or multi-repo estates.

It materializes that information as a durable OKF graph using a standard OKF schema pack (plus PKC) so agents and humans can query topology, ownership, and blast radius with precision.

- Microservices, web apps, APIs, packages, monorepos / multi-repos
- Dependency graphs and build artifacts (npm · maven · gradle · go · cargo · pip: common model)
- Containers (Docker/containerd/CRI-O) and serverless (Lambda, Cloud Functions, Azure Functions)
- CloudFormation · Terraform · CDK · Pulumi · Helm · Kustomize · Kubernetes

## Skills

- sac-blast-radius: Compute and optionally write blast-radius analysis for a service or concept through the SAC graph.
- sac-c4: C4 model integration for the architecture second brain. Map System/Person/ SoftwareContainer/Component/Code, generate L1: L4 Mermaid views, import Structurizr DSL, and avoid Docker vs C4 Container confusion.
- sac-capture-diagrams: Capture wireframes and architecture diagrams into the SAC second brain as OKF concepts with Mermaid or PlantUML listings embedded in Markdown. Covers wireframes (PlantUML salt), architecture, component, sequence, activity, state machine, class, ERD, deployment, C4, and data-flow diagrams. Also use…
- sac-capture: Materialize a scan (or live scan) into SAC OKF concepts under the knowledge bundle.
- sac-design-with: Use the SAC architecture second brain when designing new features, services, APIs, mobile apps, web apps, or infra. Loads progressive-disclosure packs (blast radius, contracts, deps, environments) so design work reuses existing topology instead of inventing in a vacuum. Trigger on design, new servi…
- sac-doctor: One-screen health check for SAC knowledge bundles (types, thin concepts, broken links).
- sac-graph: Export the architecture dependency graph as JSON or Mermaid from a SAC knowledge bundle.
- sac-ingest-tickets: Ingest Jira/Linear/Azure DevOps/GitHub Issues JSON exports into TicketLink and Feature concepts.
- sac-ingest-wiki: Ingest Confluence/Notion/wiki Markdown exports into ADRs, glossary terms, runbooks, and discoveries.
- sac-init: Scaffold a System Architecture Capture knowledge bundle with SAC + PKC catalogs for reverse-engineering systems into OKF. Use when starting architecture capture in a repo.
- sac-link: Add typed architecture edges between SAC concepts (calls, exposes_api, deploys_to, secured_by, …).
- sac-pack: Build progressive disclosure context packs (default 2-hop) for precise LLM queries over architecture knowledge.
- sac-plan
- sac-retrieve
- sac-reverse-engineer
- sac-scan
- sac-search
- sac-session
