DxC: Natural-Language Content Workbench with 8-Step Pipeline & Local Memory

DxC is a personal content workbench that uses natural language to orchestrate an 8-step production pipeline — research, brief, outline, draft, title, visuals, review, and WeChat draft delivery — backed by local hybrid retrieval (SQLite FTS5 + BGE embeddings) and a four-layer memory system that persists across projects.

Architectural Evolution of a Workflow Agent Native Product: DxC's Boundary Redefinition

This article details the architectural evolution of DxC, a workflow-type Agent Native product for WeChat content creation, describing how it progressed from Skills-driven workflows to a three-boundary architecture separating Agent intent, Skill interaction, and deterministic machine contracts, with principles for tool design, opaque work items, and a five-layer verification strategy.

How Enterprises Build Their Own AI Intelligence Production Line: Sequoia's Sovereign AI Deconstructed

Sequoia Capital's Sovereign AI framework reveals how enterprises can build continuous learning loops by capturing production traces, defining private evaluations, constructing RL environments, and localizing failures across context, harness, and model layers to turn real work into proprietary intelligence.

Why Agents Overstep Skill Constraints: How Ambiguity Triggers Error Cascades

The author analyzes why AI agents like WorkBuddy violate Skill constraints in the DxC writing system, identifying three failure modes, two anti-patterns, and how moving orchestration back to deterministic CLI in v0.3 reduced but didn't eliminate boundary issues, highlighting the need to separate probabilistic judgment from deterministic state management.

Why I Rejected a Web UI for My Agent-Native Writing System

The author describes building DxC, an Agent-Native WeChat writing system, explaining why they chose a Skill+CLI architecture over a complete Web prototype, and how removing forms shifted determinism burdens to the agent architecture, causing issues like skipped steps, parameter errors, and idempotency risks.
