Autonomous Coding Agents via OpenAI Symphony + Linear

Alessio Fanelli (founder of Kernel Labs) demonstrates running autonomous coding agents from a phone using OpenAI Symphony orchestrated with Linear as an agent state machine. The episode covers a fully autonomous development workflow (Symphony managing agents across the dev lifecycle, Linear providing state tracking), cost and token accounting, and enhanced agent sensing with tools like Glimpse. Fanelli also demos OpenAI Codex autonomously browsing eBay to scout underpriced PSA‑graded Pokémon cards, extracting certificate numbers and flagging $10K–$20K deals for his San Carlos card shop, Merlin Games. The episode is published July 6, 2026 and is available on YouTube, Spotify and Apple Podcasts; sponsors include Firecrawl and Jira Product Discovery.

How I AI: Sonnet 5 Benchmark and Agent Workflows

A two-part How I AI newsletter episode: Claire benchmarks Anthropic’s new Sonnet 5 using a repeatable “How I AI Bench” built with Claude Code, blind-testing Sonnet 5 against Sonnet 4.6, Opus 4.8, GPT-5.5, and Gemini 3 Pro across PRDs, prototypes, agentic tasks, and personality. Sonnet 5’s introductory pricing ($2 per million input tokens, $10 per million output tokens through the end of summer) positions it between prior Sonnet releases and Opus; Claire found human judgement diverged sharply from LLM-as-judge scores. Separately, Alessio Fanelli (founder of Kernel Labs) demonstrates managing autonomous coding agents from mobile using OpenAI Symphony, Linear, and cloud VPS, highlights token-cost tracking, skills-file hygiene, and perception tooling (Kernel Labs’ Glimpse) to extend autonomous runs. The issue emphasizes building repeatable benchmarks and operational practices for agentic workflows.

One-Call API to Price Luxury Watches

A developer published an Apify actor, chrono24-watch-analyzer, that returns a single structured market analysis (median, percentiles, market depth, certified-share, dealer-country mix, confidence) for a queried luxury watch model by scraping Chrono24 and cleaning listings. The pipeline removes promoted cards, accessories, parts, replicas and duplicates before computing statistics and labels results with a price basis of "asking." The actor supports six Chrono24 domains (.com, .es, .de, .fr, .it, .co.uk), batch mode up to 25 models, and integrates with Apify's MCP for use by AI agents. Pricing is $0.02 per analysis (no charge if a query legitimately returns no data). The author documents parsing and filter pitfalls and provides the cleaned comps behind each metric for auditing.
