How to Avoid Runaway API Costs in OpenClaw | Brian Gershon Routing every OpenClaw request, from background tasks to complex reasoning, through a premium model adds up fast. Here is how to right-size it.

$25 in API charges after one day running OpenClaw on defaults. A few config changes cut that dramatically.

Building OpenClaw-style agents? Here is how to run skills without API keys in the agent container.

Pattern: two containers - agent posts to an internal URL, tool service holds the credential. The key never crosses into agent space.

Supercharging Claude Code with the Right (CLI) Tools Ten CLI tools recommended by Claude Code itself, ranked by how much they’d boost its productivity.

Claude Code was asked what tools would make it most effective.

Top picks: ast-grep for structural code search, difftastic for AST-based diffs, shellcheck for shell script safety. Tools that let AI work on code structure - not just text patterns.

Make the Tool You Wish Existed (with Your LLM) | Brian Gershon Build custom HTML tools that fit your exact workflow using LLMs. No extensive programming knowledge required. Turn workflow problems into practical tools in hours.

Want to try vibe coding without production software complexity?

HTML tools are the perfect playground for LLM-assisted development.

Single files, no deployment, no dependencies. Just experiment and iterate.

Build a Registry of AI Tools. Generate MCP Servers and CLIs. | Brian Gershon Define prompts and tools in markdown files by describing them to an LLM. A registry framework converts those markdown specs into MCP servers and CLI tools automatically. You iterate in markdown, not f...

I wanted portable AI tools you can spin up by describing them, not hand-coding MCP servers.

Describe what you want once. A registry turns that into MCP servers and CLIs that any AI coding assistant can use.

One definition, every assistant and format you need.

How to Correct AI Errors When Analyzing Customer Reviews | Brian Gershon When AI generates customer review summaries and trends, it hallucinates numbers and names. Learn how verification tools and feedback loops catch these errors automatically and teach AI to correct its ...

When AI summarizes customer reviews, it often invents names and numbers that look real but aren’t.

We saw this in weekly reports across Google, DoorDash, Yelp. Strong insights, wrong facts.

Fix: teach AI to verify its own work, not just summarize data.

This is a very major rewrite, and also open sourcing of the whole codebase - with more features yet to come!

Events connect people - the exact kind of thing that should be available on an open protocol.

this might finally get me to publish sh.tangled.*
