fff.nvim is a Rust-built file search toolkit with a dual identity: a Neovim plugin for human developers and an MCP server for AI coding agents. The core insight is that both humans and AI models need context-relevant file discovery, and the same algorithm serves both use cases well. The scoring system combines frecency (frequency + recency), git status (modified/staged files score higher), file size (prefers smaller files that fit in context), and definition match (files containing definitions of symbols you're searching). The result is that the most likely relevant file surfaces first, reducing the token cost of codebase exploration for AI agents by avoiding the need to open and read many irrelevant files. The MCP integration is the breakout feature — AI agents using tools like Claude Code or Cursor can invoke fff.nvim's search capabilities directly, getting curated file suggestions instead of brute-forcing directory traversal. fff.nvim trended at #5 on GitHub today with 767 new stars, suggesting strong interest from the developer community that runs both human and AI development workflows.

Waydev has relaunched as the measurement layer for AI-written code, letting engineering teams track which AI agent wrote which code, tokens consumed per PR, cost-per-shipped-line, and acceptance rates — with a unified comparison dashboard across GitHub Copilot, Cursor, Claude Code, and other AI coding tools. Founded in 2017 and backed by Y Combinator (W21), Waydev spent nine years building engineering analytics infrastructure. The pivot to AI SDLC measurement uses that existing integration surface (GitHub, GitLab, Jira, Linear) to add agent attribution metadata on top of existing flow metrics. The result is the first tool that can answer 'our team spent $4,200 on AI coding tools last month — which $1,000 was actually worth it?' With enterprise engineering budgets now routinely including five-figure monthly AI tooling costs and no standardized way to measure output quality by tool, Waydev's timing is sharp. The YC pedigree and existing customer relationships mean this isn't starting from zero — they're adding a new measurement layer to existing installed base.
Reviewer scorecard
“The frecency + git status scoring is exactly the heuristic I apply manually when navigating large codebases. Giving AI agents access to that same signal via MCP is a practical efficiency gain — fewer context tokens wasted on files that aren't what the model needs.”
“The 'which AI tool actually shipped good code' question is one every eng manager is asking. Waydev's existing Git integration means the attribution layer isn't a cold-start problem — if you're already using it for velocity metrics, the AI measurement upgrade is an obvious yes.”
“Frecency works well for personal workflows but can mislead AI agents on shared repos where your personal access patterns don't reflect what's architecturally important. The 'skip large files' heuristic is also a double-edged sword — some critical config files are large for good reason.”
“Measuring AI contribution by tokens or accepted suggestions is a proxy for value, not value itself. Code quality, bug rates, and time-to-review are better signals, and those are already available in existing tools. Enterprise pricing with no numbers on the website signals this is expensive; wait for a published case study with real ROI data.”
“This is an early example of tooling built simultaneously for humans and AI agents — a design pattern we'll see everywhere as coding workflows become hybrid. The shared context between how a human navigates a repo and how their AI agent does will be a meaningful collaboration advantage.”
“As AI coding tools proliferate, the meta-layer question becomes 'which tool compound returns the best for which task type and team composition?' Waydev is building the dataset that will eventually answer that — and the company that owns that benchmark data owns significant influence over enterprise AI tool purchasing decisions.”
“For creative projects with complex file structures — design systems, multi-locale content, large asset libraries — intelligent file search that understands recency and relevance is a genuine workflow improvement over fuzzy find.”
“For creative technologists who switch tools constantly by feel, a measurement dashboard adds overhead that slows down experimentation. The ROI framing is enterprise-first; indie builders will be better served by just trying tools and shipping.”
