qmd is a lightweight local search engine built by Tobi Luetke, CEO of Shopify, for indexing and querying personal knowledge bases, documentation, and meeting notes — entirely offline. It combines three retrieval approaches in a single pipeline: BM25 full-text search for exact keyword matches, vector semantic search via ONNX-based embeddings, and LLM re-ranking using GGUF models through node-llama-cpp. All three stages run locally with no cloud dependency. The tool ships in multiple deployment modes: a CLI for ad-hoc queries, a Node.js library for programmatic use, an HTTP service for local API access, and — most useful for AI workflows — a native MCP server that lets Claude Code, Cursor, and similar editors query your local knowledge base directly during coding sessions. The hybrid retrieval approach means it handles both "find the exact error message from last week's standup notes" and "what was our decision about the auth architecture" equally well. What makes this notable beyond its technical approach is provenance: Luetke shipped it as a personal tool he actually uses, not a startup product. The GitHub history shows active iteration and he's been talking about it on X. It's a credible signal of where pragmatic AI-augmented knowledge management is heading for technical users who prefer local-first tools.

Windsurf SWE-Agent 2
Multi-repo AI agent that executes cross-service engineering tasks end-to-end

Windsurf SWE-Agent 2 is an AI software engineering agent that can execute tasks spanning multiple repositories simultaneously, resolving cross-service dependencies and writing tests end-to-end. It integrates directly into the Windsurf IDE and supports GitHub Actions for CI/CD pipeline automation. The agent is designed to handle real-world multi-service codebases rather than single-file or single-repo tasks.
Reviewer scorecard
“Hybrid BM25 + vector + LLM re-rank is the right architecture for personal knowledge search — each layer catches what the others miss. The MCP server mode is genuinely useful: being able to ask Claude Code 'what did we decide about X last month' against my own notes changes the workflow. MIT licensed and from someone who ships real products.”
“The primitive here is a task-execution graph that can span repo boundaries — not just file edits, but dependency resolution across services, with test generation wired in. That's a genuinely hard problem and the right DX bet is embedding it in the IDE rather than making it a separate CLI or SaaS dashboard you have to context-switch into. The GitHub Actions integration is the moment of truth: if the agent can open a PR that passes CI on a realistic monorepo-plus-microservices setup without manual cleanup, that's not replicable with three API calls and a Lambda. My one callout: the blog post claims cross-repo dependency resolution but shows no concrete benchmark or failure-mode documentation — I want to see what happens when the agent hits a circular dependency or a private package registry before I call this fully earned.”
“This is a well-executed weekend project, not a production tool. It requires GGUF models and manual embedding setup — a meaningful friction barrier for non-technical users. The 'built by a CEO' narrative drives GitHub stars more than the technical differentiation. Obsidian with a local AI plugin gets you here with better UX.”
“Direct competitors here are Devin, GitHub Copilot Workspace, and Cursor's background agent — all of which are also claiming multi-repo execution right now, so the category is real but crowded. The specific scenario where SWE-Agent 2 breaks is any organization with non-standard monorepo tooling: Bazel, Pants, or Nx with custom executors will expose whether the agent actually understands build graphs or just pattern-matches on package.json files. What kills this in 12 months: GitHub ships Copilot Workspace with native Actions integration at no additional cost to Enterprise customers, and Windsurf's differentiation collapses to IDE preference. What would have to be true for me to be wrong: Codeium has trained on enough real multi-repo codebases that the agent has genuine structural understanding competitors can't replicate quickly — possible but unverified.”
“The pattern here — local hybrid retrieval as an MCP server feeding into AI coding agents — will be ubiquitous in two years. Today it's a technical power-user tool; tomorrow it's how everyone's AI assistant knows the institutional context behind the code. qmd is an early, clean implementation of that pattern.”
“The thesis here is falsifiable: by 2027, the unit of AI-assisted development is not the file or the PR but the cross-service feature, and the agent that owns task orchestration across repo boundaries becomes the default interface for engineering work. The dependency that has to hold is that model context windows and tool-call reliability continue improving faster than the complexity of real codebases grows — right now that race is genuinely close. The second-order effect nobody is talking about: if multi-repo agents work, they don't just speed up individual engineers, they make small teams structurally capable of maintaining service meshes that previously required platform engineering headcount, redistributing leverage away from large eng orgs toward startups. Windsurf is on-time to this trend, not early — Devin and SWE-bench have already established the category — but the IDE-native embedding is a real structural advantage over agent-as-a-service competitors.”
“I manage a lot of notes, references, and creative briefs, but the setup friction here — GGUF models, CLI configuration — makes this inaccessible for most creators. The concept is great; the UX needs a front-end before it reaches beyond developers.”
“The buyer is a VP of Engineering or a senior developer lead at a company with genuine multi-repo complexity — that's a real person with a real budget, probably coming out of tooling or platform eng spend. The problem is pricing: bundling the most compelling enterprise feature into a per-seat subscription means Windsurf is pricing on seats, not on value delivered, and a team that saves 20 hours of cross-service debugging per week should be paying a lot more than $35 per seat per month. The moat question is unresolved — the IDE is stickier than a web app but less sticky than a proprietary data asset, and if OpenAI or Anthropic ships a general coding agent with tool-call APIs, Codeium's model investment may not be defensible. What needs to change: usage-based pricing tied to tasks completed or PRs merged, which would both capture more value and create a clear signal that the agent is actually working in production.”
