MDV (Markdown Data Views) is a markdown superset that extends standard .md files with embedded live data, interactive charts, and presentation-ready slides. The goal is a single document format that serves simultaneously as developer documentation, a live dashboard, and a shareable slide deck — without requiring a separate tool for each use case. MDV files can embed SQL queries, API calls, and data transforms directly in markdown, with results rendering as tables, charts, or visualizations on the fly. The syntax extends frontmatter conventions that markdown users already know, keeping the learning curve minimal. Output can be previewed in a local server, exported as HTML, or converted to a slide deck — the same source file serves all three outputs. MDV surfaced on Hacker News with 44 points and active discussion around the concept of "living documents" — reports and runbooks that stay current because their data sources are live queries rather than screenshots. For developer-heavy teams who live in their editors and resist adopting heavyweight BI tools, MDV offers a markdown-native alternative that slots into existing documentation workflows.

Superpowers
Composable workflow framework that forces AI coding agents to write tests first

Superpowers is an open-source framework by Jesse Vincent (obra) that imposes a disciplined 7-phase software development workflow on AI coding agents: brainstorm → git worktrees → plan → subagent development → test-driven development → code review → branch completion. The core insight is that agents like Claude Code and Codex will skip tests and architectural planning if not explicitly constrained — Superpowers enforces these phases via structured prompts and hooks that agents cannot easily bypass. The framework works across Claude Code, Cursor, Codex, Gemini CLI, and GitHub Copilot CLI. Each phase has defined inputs, outputs, and acceptance criteria, and agents use git worktrees to isolate branches so failed experiments don't contaminate main. The TDD phase is mandatory: tests must be written and passing before any implementation code is reviewed. V5.0.7, released March 31, fixed Node.js 22+ compatibility and added Codex App support. As of April 8, 2026, Superpowers is the #1 trending repository on GitHub with 1,926 new stars today, bringing its total to 141k. It's one of the fastest-growing developer tools of 2026 — growing from ~27k stars in January to 141k in under three months.
Reviewer scorecard
“I've been writing separate README, dashboard, and slide deck for the same data for years. MDV collapsing those into one source-of-truth file is the kind of DRY solution I didn't know I needed. The frontmatter-extension approach means it works in existing markdown tooling. Shipping for internal docs immediately.”
“141k stars doesn't lie — this fills a real gap. Claude Code is brilliant at generating code and terrible at knowing when to stop and write a test. Superpowers adds the engineering discipline that solo devs usually skip under deadline pressure. The git worktree isolation is a particularly smart detail that prevents agent experiments from trashing your main branch.”
“Embedding live SQL queries in documentation is a security and maintainability footgun. Who reviews the data access in a markdown file? The concept is compelling but the execution needs a clear story for access control, query sandboxing, and handling stale or broken data connections in production docs.”
“The 7-phase workflow adds significant overhead for simple tasks — if you're just fixing a bug or adding a small feature, going through brainstorm → worktrees → subagents → TDD → review is overkill and will frustrate developers who just want to ship. The star count reflects GitHub trending momentum as much as actual adoption.”
“The next evolution of documentation is documents that are executable — that don't just describe the system but are the system. MDV is an early step toward that: markdown that isn't just readable by humans but queryable, renderable, and automatable by agents. Worth watching closely.”
“What Superpowers is really doing is encoding decades of software engineering best practices into a prompt-based specification that AI agents can follow. As agents become more autonomous, frameworks like this become the guardrails between 'AI that writes code' and 'AI that ships reliable software.' The TDD enforcement alone could prevent enormous amounts of AI-generated technical debt.”
“Being able to write a client report in markdown that automatically pulls live data and renders as a slide deck is genuinely transformative for independent consultants and content creators. MDV could replace Notion, Google Slides, and a BI tool for a substantial percentage of small team workflows.”
“As someone who uses AI coding tools to build side projects, the biggest pain point is agents generating code that works once and breaks mysteriously later. Superpowers' mandatory test phase would have saved me countless debugging sessions. It's more structure than I'd set up myself, which is exactly the point.”
