Blast Radius Tiers: A Permission Model for Agents That Act
Anthropic found users approve 97% of permission prompts while human review catches 13.6% of dangerous commands. Approval was already theatre. Here is the tier model that replaces it.
How to Build a Local Agent Bridge: Context and Failures
The HTTP in a local agent bridge is twenty lines. Compiling context and designing failures is where the real work is. Here is how both are built.
Three Bugs My Test Suite Could Not Find
A green test suite and a working system are different things. Three bugs from one afternoon of real use, and why each was invisible to the tests.
What Is a Local Agent Bridge? Transport and Auth Rules
A local agent bridge lets a browser extension, Slack bot or CI runner call a coding agent on your machine. Here is what decides the transport.
Graph Engineering: When an Agent Loop Should Be a Graph
Graph engineering moves agent control flow from inference time to authoring time. When a loop should become a graph, and what each pattern actually costs.
The Math That Kills Most Multi-Agent Pipelines Before They Ship
The best AI agent succeeds at 30% of office tasks. Chain three together and end-to-end success drops to 34%. This is the compounding failure math every AI engineer needs to run before building.
Why Your AI Agents Keep Failing (It Is Not the Model)
58% of agent bugs live in the context layer, not model weights. A breakdown of the context engineering failures causing production AI agents to fail, with real incident analysis.
Your Agent Swarm Is Probably Just Expensive Ensembling
A multi-agent swarm can beat one model on decisions, but debate often loses to self-consistency at equal compute. Four conditions under which the swarm actually earns its cost.
The Verification Burden Your AI Product Ignores
Accuracy is a lagging indicator. A controlled study found AI made expert developers 19% slower, because the work moved into reviewing. Here is the number to optimize instead.
The Shape of a Coding Agent: 544 Lines That Matter
I read Tau, a 225-file terminal coding agent, as a knowledge graph. The whole coding agent architecture turns on one idea. The event stream is the contract.
