Caveman is a Claude Code skill and AI editor plugin that makes language models respond in compressed, fragment-based prose — dropping articles, filler, and pleasantries while keeping full technical content intact. It offers four intensity levels from Lite (removes fluff, preserves grammar) to Ultra (telegraphic shorthand) and even a classical Chinese mode (文言文) for extreme compression. The result: roughly 65–75% fewer output tokens on average. The plugin ships with companion utilities: caveman-commit for sub-50-char commit messages, caveman-review for one-line PR verdicts with inline annotations, and caveman-compress to shrink documentation fed into sessions by ~46%. Installation is a single command across Claude Code, Cursor, Windsurf, Codex, Copilot, and 40+ other editors via the skills ecosystem. With 27k+ GitHub stars since its Product Hunt launch today, Caveman has struck a nerve with developers who are burning through token budgets on Claude's verbose default style. It's arguably the simplest ROI improvement you can apply to any AI-assisted coding workflow today.

farmer is an npm package that intercepts tool-call permission requests from AI coding agents and routes them to a mobile-friendly dashboard. Instead of watching a terminal scroll as Claude Code or another agent quietly runs shell commands, you get a swipe-card view on your phone where each pending tool call shows the command, its arguments, and the agent's reasoning — and you approve or deny with a swipe. The architecture is deliberately simple: farmer acts as a hook in the agent's tool-call loop, holds execution until you respond, then forwards your decision back. It ships with a Claude Code adapter out of the box and a documented adapter interface for other agents. The mobile UI is a PWA, so there's nothing to install — just navigate to the local server address in Safari or Chrome. For developers running long agentic sessions — overnight refactors, automated test generation, or repo-wide migrations — farmer fills a real gap. Current tools either block the terminal or run with blind trust. farmer offers a middle path: human-in-the-loop control without requiring you to be physically at your machine.
Reviewer scorecard
“This is one of the most practical DX improvements I've seen in the Claude Code ecosystem. Token budgets are a real constraint, and cutting 75% of output without touching correctness is legitimately impressive. One-command install across every editor seals it.”
“This solves the exact anxiety of kicking off a Claude Code session and then walking away. The swipe-card mobile UI is well thought out — you can do a quick code review of the pending command right from the notification. The adapter interface is clean enough that I could wire it to my own agents in an afternoon.”
“The 75% figure is self-reported and depends heavily on use case — code-heavy tasks already have dense outputs. There's also a real risk that terse AI responses miss critical nuance in complex debugging sessions, which could cost more time than the token savings are worth.”
“The security model is concerning: you're routing tool-call details through a local WebSocket server that's exposed to your network. Anyone on the same WiFi can potentially see (or intercept) pending commands. There's no auth on the dashboard in v0.1. Fix that before using this on anything sensitive.”
“This points toward a future where AI assistants adapt their verbosity to context automatically — terse for experienced devs, explanatory for learners. Caveman is a blunt instrument today, but it's validating an interface paradigm shift. The 27k stars say the market agrees.”
“Human-in-the-loop approval is going to become a compliance requirement for agentic AI in enterprise settings. farmer is ahead of the curve — the patterns it's establishing for mobile-first agent oversight will likely influence how official agent SDKs handle permission gating.”
“The Wenyan (classical Chinese) mode is genuinely inspired as a design choice — it reframes token compression as an aesthetic rather than a tradeoff. The branding is memorable and the single-sentence tagline does exactly what the product does.”
“I run AI agents to manage my content pipeline and frequently can't be at my desk. The idea of approving file writes and API calls from my phone while I'm at a coffee shop is exactly what I've wanted. The activity feed is a nice touch for auditing what ran while I was away.”
