https://logic64.com/blog/why-ai-coding-agents-hallucinate-architecture https://logic64.com/media/diag-14-where-drift-comes-from.svg None of these four steps looks like a failure. That's exactly the problem. Diagram: a prompt is a request, not a constraint — the model fills a missing decision, the code compiles and runs, and the boundary has already been decided quietly, with no one held to it https://logic64.com/media/diag-04-governed-vs-unconstrained.svg Same prompt, two processes. The difference is whether anything checks the output before it ships. Diagram comparing the same prompt through two processes: without guardrails it ships unchecked, under the governed pattern it is locked and validated before it ships https://logic64.com/media/diag-02-plan-build-pull.svg How Logic64 applies the pattern above: Plan, Build, Pull. Diagram of the Plan, Build, Pull lifecycle with each stage's real output https://logic64.com/blog/spec-driven-development-with-claude-code-and-cursor https://logic64.com/media/diag-05-vibe-coding-session-drift.svg Neither session knew what the other one decided — the collision just takes two weeks to surface. Diagram of two separate vibe-coding sessions, days apart, silently assuming different things about the same system, colliding two weeks later as a rewrite https://logic64.com/blog/what-belongs-in-a-claude-md https://logic64.com/media/diag-06-claude-md-belongs-vs-not.svg Both lists above, side by side. Diagram: what belongs in a CLAUDE.md file versus what does not — exact commands, locked stack, approval boundaries, and doc pointers belong; directory trees, restated decisions, style opinions, and marketing copy do not https://logic64.com/blog/plan-generate-pull-architecture-first-ai-workflow https://logic64.com/media/diag-01-system-dataflow.svg How a request actually moves through the system, end to end. Diagram of the Logic64 request flow: Frontend to Backend to Queue to Engine, with the SSE stream flowing back and the separate CLI acknowledgement request https://logic64.com/media/diag-02-plan-build-pull.svg The same three phases, laid out end to end. Diagram of the Plan, Build, Pull lifecycle with each stage's real output https://logic64.com/blog/logic64-vs-raw-prompting https://logic64.com/media/diag-07-risk-vs-scale.svg The risk doesn't show up on day one. It shows up as the system grows. Chart showing the risk of an unreviewed assumption causing a bug rising sharply under raw prompting as system complexity grows, while staying low and flat under Logic64's locked architecture https://logic64.com/blog/ai-coding-guardrails-for-production-teams https://logic64.com/media/diag-08-guardrail-pipeline.svg Four gates, each one able to say no. Diagram of a generated artifact passing through four checks — schema, routing, dependency approval, and layer boundaries — any of which can reject it before it ships https://logic64.com/blog/claude-md-vs-skills https://logic64.com/media/diag-03-where-things-live.svg Two different loading models, one shared source of truth underneath both. Diagram showing CLAUDE.md loaded on every session, a Skill loaded only on demand, and both reading from the same docs/okf/ knowledge tree https://logic64.com/blog/mcp-server-setup-guide https://logic64.com/media/diag-09-mcp-connection-map.svg The worked example above, as a connection map — the secret is resolved outside the file, never inside it. Diagram of Claude Code connecting through three MCP servers to a local filesystem, a Postgres database, and GitHub, with the database credential referenced as an environment variable rather than written into mcp.json https://logic64.com/blog/how-to-structure-a-saas-project https://logic64.com/media/diag-01-system-dataflow.svg One predictable request path, plus the async legs it doesn't block on — this is that pattern in a real system. Diagram of the Logic64 request flow: Frontend to Backend to Queue to Engine, with the SSE stream flowing back and the separate CLI acknowledgement request https://logic64.com/blog/cursor-rules-explained https://logic64.com/media/diag-10-cursor-rules-actual-comparison.svg The pairing everyone searches for isn't the one that actually matches. Diagram: Cursor rules and CLAUDE.md are both always-on context, the actual comparison; a Skill is a separate category, on-demand capability, not comparable to either https://logic64.com/media/diag-11-cursor-migration-map.svg Same role, different file — plus one extra layer. Diagram: Cursor rules map directly to CLAUDE.md, and Skills sit on top as an additive, on-demand layer, not a replacement for either https://logic64.com/blog/best-ai-coding-assistant-tools-compared https://logic64.com/media/diag-12-three-different-shapes.svg Same problem space, three different shapes. Diagram of three different shapes: GitHub Copilot is a plugin inside many editors, Cursor is one self-contained AI-native editor, Claude Code is a CLI tool tied to no editor at all https://logic64.com/media/diag-13-where-logic64-fits-layer.svg Not a fourth option in the table above — a layer underneath all three. Diagram showing Logic64 as a different layer, not a competing coding assistant: it locks the architecture, produces a governed workspace, and any assistant then works inside it
