Running agent-generated code in a plain Docker container trusts a boundary built for reviewed workloads. MicroVMs give you a real kernel per execution at roughly 125ms boot.

A test written by the same agent that wrote the implementation is a mirror, not a check. Which TDD invariants survive agent authorship, and the mutation-testing gate that catches the rest.
August 18, 2026 AI ToolsContext engineering borrowed cache vocabulary but skipped the part that matters: key design. Here's how versioned, provenance-based keys fix stale retrieval where TTL clocks can't.
August 17, 2026 AI AgentsOpenAI's Ultrafast tier hits 750 output tokens/sec on Cerebras hardware. Whether that changes your agent's wall-clock time depends on one ratio you can measure in 20 lines of Python.
August 14, 2026 AI AgentsMeta's Muse Glimmer is 30B params under Apache 2.0 and ships with no documented tool-call schema. Three concrete audit steps to run before it touches your agent stack.
August 10, 2026 AI AgentsPer-call RBAC can't say "deny this refund because a cancellation already happened." Sequence-aware authorization for AI agents is two Postgres tables and one plpgsql function.
August 10, 2026 AI AgentsRole confusion exploits how text sounds, not which role tag it carries. The fix isn't a filter — it's a trust-level envelope in your message construction code. Here's the structural patch.
June 24, 2026 AI AgentsPublic leaderboards score tool calling on clean synthetic schemas, not the nested mess your MCP server exposes. Here's the ~50-line Python harness that settles the debate on your own stack.
June 19, 2026 AI AgentsLong agent loops collapse around turn 8 — not because the window is full, but because tool results silently eat the budget. Here's the audit pattern and checkpoint prompt to fix it.
June 01, 2026 AI AgentsCoding agents relocated your cognitive load from writing to reviewing — and judgment degrades fast. Here's a preamble prompt and a three-tier triage that cut the fatigue.
May 28, 2026 AI AgentsAn AI agent resolved an RLS error by making the table publicly readable. CI stayed green. Here's the grep triage and checklist I run before any LLM-generated code ships.
May 22, 2026 AI ToolsPure cosine similarity returns garbage on version numbers, SKUs, and exact phrases. The fix is hybrid search in Postgres — two indexes, one CTE, and a rule for which leg to weight.
May 18, 2026 WorkflowsMost LLM features ship on vibes — skim three outputs, merge. Here's the 40-line Python eval harness with JSON fixtures and a judge-model gate you can wire into CI today.
