Stop making your agent navigate your codebase without a map, its inconsiderate. Before it starts working, have it build a knowledge graph of the codebase so it actually has a map of the whole thing. Vector databases embed and index your code for semantic search, but I prefer...

Chrome DevTools MCP is insane for frontend dev. It gives your agent X-ray vision into the browser while it tests what youre building - it reads console logs, runtime errors, stack traces, hydration issues, failed API calls, bad auth headers, CORS errors, missing assets. It...

I deleted all my MCP servers and replaced them with CLI tools, and saved an average of 40% of my context window. Its also faster, because when Claude Code uses an MCP tool a bunch of extra JSON schema gets injected into context, but a CLI tool dynamically generates a bash...

If you're not using Claude Code to drive Codex you're probably burning tokens and shipping worse code. There's a plugin that lets Claude Code call Codex directly, and once you've run both you see exactly why it works. Claude Code is better at the orchestration and multi-agent...

If you run both Codex and Claude Code you've probably felt the pain of keeping their configs in sync. Here's how I actually solved it. agents.md is the canonical instructions file now, so instead of maintaining a separate CLAUDE.md, just import agents.md into it and you're...

Stop letting your coding agent commit to its first idea. Branch and prune: fan out adversarial variations through sub agents, then pick the strongest. Works for architecture, features, UI, even copy. Even better across Gemini, Codex, and Claude. Comment branch for the skill.

[James Goldbach @agentic_james]

One memory across Claude, ChatGPT, Gemini, and every AI tool. Runs on Hindsight, a cloud memory database with an MCP server, so every app points at the same brain. Retain, recall, reflect. Cleanest fix for memory living in ten silos. Comment memory for the link.

[James Goldbach @agentic_james]

I built a skill that turns any video into an actionable skill for your agent. Send it any link, it scrapes and transcribes the post, enriches it with web research, and turns it into concrete steps for your setup. Runs on Apify. Link in bio.

[James Goldbach @agentic_james]

The easiest vector DB knowledge base for your AI agents: NotebookLM. No RAG, no Supabase setup, just connect your agent to the NotebookLM MCP server. You lean on Google's semantic search across thousands of docs, retrieval pre-filtered through free Gemini credits. Link in bio.

[James Goldbach @agentic_james]

My Claude Code improves its own skills overnight. Every tool call is stored in a JSONL transcript, so one agent grades another's run after it uses a skill, finds what broke, and rewrites the skill so the next run is better. Skills that sharpen while you sleep. Link in bio.

Vibe-coding consumer apps without security testing means shipping exploits you can't see. Shannon is an agentic hacker that maps your attack vectors and runs real exploits on your live app. Light version is open source. Comment SECURITY and I'll send the repo.

[James Goldbach @agentic_james]

One of the most useful tools I've touched all year and nobody's talking about it: the understand-anything repo turns any codebase into an interactive knowledge graph. It even shows a PR's full impact before you push. Comment UNDERSTAND and I'll send the repo.

[James Goldbach @agentic_james]

The Claude Code features that separate the top 1%: background sub-agents running in parallel, hooks that intercept or block actions, skills in forked context windows, and agent teams that message each other while they work. Master these four. Full masterclass, link in bio.

[James Goldbach @agentic_james]

The easiest agentic AI automation for your business takes five minutes and most people sleep on it. Claude Code's routines tab schedules a prompt to fire daily inside a folder on your machine. Mine deploys sub agents to research products, run sourcing math, and drop a report every day on its own. Full masterclass in my community, link in bio.

[James Goldbach @agentic_james]

Having a dedicated Codex computer-use agent inside my system is honestly insane. It drives every actual desktop app on my computer. My content agent writes a script, opens my video editor, drops the script in before I record, then after I edit it pulls the file, goes to the...

[James Goldbach @agentic_james]

Can we as a community agree to stop putting API keys in a .env file when you're using coding agents. That file is not a secret vault, it's just a file. The key linked to your OpenAI account, which is linked to your bank, ends up sitting in your agent's session transcript...

[James Goldbach @agentic_james]

Stop using ASCII diagrams to plan your UI, use HTML specs instead. I just mean a quick HTML mockup of the screen you want the agent to build. It's dirt cheap to generate and you get the actual layout plus every state, error, loading, toggles, all of it. You can bake local...

[James Goldbach @agentic_james]

If you're still connecting MCP servers the normal way you're burning a stupid amount of tokens. One response body can dump tens of thousands of tokens straight into your context and you have zero control over it. The fix everyone's moving to is programmatic tool calling, you...

[James Goldbach @agentic_james]

Ranked every agentic coding harness I actually use. OpenClaw drops to D, it breaks every time they ship an update and the codebase is a slop factory. Pi lands in B, rock solid and barely touches memory. Hermes is A, less for session coding and more for running a 24/7 agent in...
