AI Subroutines from rtrvr.ai are a new automation primitive: you record a browser task once (a form submission, a LinkedIn connection, a CRM update), and that recording becomes a deterministic, callable tool that AI agents can invoke with different parameters — without spending tokens on every run. Unlike Playwright, Browser-Use, or other out-of-process solutions, Subroutines execute entirely inside your browser tab, inheriting your live session cookies, CSRF tokens, and signed headers automatically. The technical approach is clever. During recording, the system captures network requests and DOM interactions, then ranks captured requests to identify the actual API call (filtering out analytics and telemetry). Replay-hostile identifiers are stripped while stable endpoints are preserved. The result is a script that runs in your browser context — no session rebuilding, no key extraction, no proxy rotation needed. The AI handles parameter selection; the script handles execution. The business case is clear for outreach and operations teams: bulk LinkedIn campaigns, CRM mass-updates, scraping pipelines, and form submissions that would cost hundreds of tokens per run instead execute as cheap deterministic scripts. The model positions Subroutines as the "function call" layer beneath AI agents — the actions that don't need intelligence every time they fire.

Goose is an open-source, local-first AI agent from Block (the company behind Square, Cash App, and CashApp) that runs on your machine across macOS, Linux, and Windows. Built in Rust, it's designed for general-purpose automation — coding, research, writing, data analysis — not just code suggestions. Agents can install packages, execute shell commands, edit files, test code, and browse the web through 70+ MCP-compatible extensions. In April 2026, Goose crossed 38,000 GitHub stars and completed its transition to the Agentic AI Foundation (AAIF) at the Linux Foundation, joining Anthropic's Model Context Protocol and OpenAI's AGENTS.md as founding projects. This governance move ensures the project stays vendor-neutral — a meaningful signal for teams worried about enterprise AI lock-in. Goose supports 15+ LLM providers (Anthropic, OpenAI, Google, Ollama, OpenRouter, Azure, Bedrock, and more), includes sandbox mode and prompt injection detection, and ships with a recipe system for portable YAML workflow configs. The Apache 2.0 license and AAIF backing make it one of the most credible options in the rapidly crowding local agent space.
Reviewer scorecard
“The 'record once, replay many' pattern solves a real cost problem in agent pipelines. The in-browser execution model is clever — you get auth context for free instead of fighting with session management. This is the kind of tool that drops into existing workflows without requiring a rewrite.”
“38K stars, Apache 2.0, built in Rust, works with every major LLM provider, has sandbox mode — and now it's got Linux Foundation governance so it won't get abandoned or enshittified. For local agent workflows, Goose is the reference implementation right now.”
“Browser automation that runs inside your session is exactly the attack surface that malicious sites exploit. Subroutines executing in-tab with full cookie access means a compromised script could do real damage. The 'zero token cost' claim also obscures that you still need LLM calls for parameter selection — the savings are real but overstated.”
“The local agent space is getting very crowded — Claude Code, Cursor, Roo Code, Amp, and now Goose all compete for the same developer mindshare. Goose's generalist positioning means it's good at everything and great at nothing. The AAIF governance is a nice story but doesn't change the UX day-to-day.”
“This is the 'compilation' step for agentic workflows — moving from 'LLM decides every click' to 'LLM selects a pre-compiled action.' That separation of concerns (intelligence vs. execution) is how you scale agent operations from one-off demos to production pipelines. The pattern will be widely copied.”
“The Linux Foundation move is underappreciated. Vendor-neutral governance for MCP + Goose + AGENTS.md means there's a neutral standards body forming around agentic AI infrastructure. That's how you prevent one company from owning the protocol layer of the agentic web.”
“For creators doing outreach, social posting, or newsletter campaigns, this is genuinely transformative. Recording a campaign action once and letting AI handle personalization at scale is the efficiency unlock that makes solo creator businesses actually viable at volume.”
“The YAML recipe system for automating workflows is genuinely useful for creative pipelines — batch processing, asset organization, research gathering. The fact that it stays local and works with Anthropic or OpenAI means you can pick your preferred model for each task.”
