Coding agents and harnesses
- michael-denyer/pstack-claude ports Poteto's Cursor-based pstack skill stack to Claude Code, Codex, Pi, OpenCode and Gemini. It tracks upstream and carries named policy forks declared in
tools/forks.json. - garrytan/gstack is Garry Tan's Claude Code setup: 23 opinionated tools acting as CEO, designer, eng manager, release manager, doc engineer and QA. It is a template for turning one agent into a role-split team.
- WXK-AI/jev-opus runs Claude Code on Opus 5.5 and asks Jev before each call whether the next step needs low, medium or high effort. Code enforces the floors and ceilings, and the prompt cache stays intact, so it is per-step effort routing without cache breakage.
- valentynkit/jev-belay is a Claude Code Stop hook from the same Jev tooling list. It is worth a look if you want end-of-turn checks wired into the harness.
- Matt Pocock's skills v1.3 ships
/retro, which mines old agent transcripts for improvements. Andre Staltz reports it surfaced problems his agents had silently worked around. - Theo's July 2026 take says Anthropic still has the best code models, but only by a small margin. He calls them slow and expensive with tight $200-sub limits, and says OpenAI is now the better daily driver. This is a useful signal for provider-switching decisions.
- T3 Code Nightly is a desktop agent app that takes your own Claude, Codex or OpenCode subscriptions. It supports multiple subs, native delegation between providers and cloud agents via T3 Connect.
Agent reliability and safety in production
- When a tool call times out, how does your agent know whether it happened? raises the core idempotency and retry problem for side-effecting tools.
- Policy-boundary starter update adds idempotency, audit logging and independent validation after production feedback.
- Before I let an agent call a tool in prod, I ask these five things is a pre-flight checklist for production tool access.
- Browser agents and fake success argues the main failure mode is an agent reporting success without the action having happened, not hallucination. This calls for verifying outcomes instead of trusting the agent's report.
- A Claude Code agent running growth for 2 weeks is a field report on which guardrails caught problems and when the agent refused.
- Are we optimizing token costs faster than agent security? frames the cost-versus-security tradeoff.
- AI agents in production: what problems are you actually facing? is a thread of operator pain points.
LLM mechanics: context and cost
- Right context beats more context argues that dumping a 200-page document into the window does not guarantee the model finds the one sentence that matters. It treats the context window as a desk where clutter hurts retrieval.
- Cheap, safe, proactive agents without noisy webhooks covers keeping event-driven agents from burning tokens on every webhook.
CLI/TUI and agent tooling
- Offline MCP and skills scanner is a free MIT scanner that audits the MCP servers and skills installed on your machine. It addresses supply-chain exposure from third-party agent extensions.
- mokkan carries reminders across Claude Code, Codex and plain terminal sessions.
- CoreSpeed bundles apps, memory and tools behind a single MCP endpoint, which would cut per-server tool-definition overhead.
Vibe-coding and agentic SaaS
- t3os is a headless, mostly Ubuntu-based OS for personal servers, built from tech choices agents prefer over humans. It ships no ISO and is not meant for a machine you use.
- Supabase as agents' top database pick credits 15+ launch weeks (75+ indexed pages) and per-competitor comparison pages. Optimizing for agent recommendation is now a distribution channel.
- OpenMontage is an open-source agentic video production system with 12 pipelines, 100+ tools and 700+ skill and knowledge files that turn a coding assistant into a video studio.
- text-to-cad is a plugin that lets agents generate STEP, GLB, STL and 3MF models. It also runs design-for-manufacturing checks and produces engineering drawings, and it works across Claude Code, Codex, Cursor and Gemini.
