Agent Loop EngineeringVersion-Controlling the Prompts in Your LoopA team changed one line of an agent prompt, shipped it, and couldn't roll back when it broke — no version history. Agent loop prompt versioning would have made it a one-line revert. Here's how.August 27, 2026·8 min read
Agent Loop EngineeringComparing Loop Traces to Find RegressionsMost teams catch agent regressions by watching aggregate metrics. That's too late and too coarse. Agent loop trace comparison finds the exact step a change broke. Here's how to do it.August 27, 2026·8 min read
Agent Loop EngineeringReplaying Agent Loops for DebuggingEver tried to debug an agent failure you couldn't reproduce? Agent loop replay lets you re-run the exact failed trace step by step. Here's the teardown of a debug setup that can't replay, and its fix.August 27, 2026·8 min read
Agent Loop EngineeringLoop Instrumentation for Production MonitoringPicture finding out your agent broke from an angry customer, not your dashboard. Agent loop monitoring turns silent failures into alerts you catch first. This case study shows what to instrument.August 27, 2026·8 min read
Agent Loop EngineeringHow Long Should an Agent Loop Run?Half of agent overruns aren't hard tasks — they're loops with no sensible length limit thrashing past the point of usefulness. Getting agent loop length right saves cost and catches bugs. Here's how.August 27, 2026·9 min read
Agent Loop EngineeringRewriting the Goal Mid-Loop: Self-RepromptingAn agent chasing a goal it had misread wasted 20 steps before failing. Agent self-reprompting lets a loop rewrite its own objective as it learns. Here's how to build it without letting it drift.August 25, 2026·9 min read
Agent Loop EngineeringBuilding a Loop That Asks for Help When StuckMost agent advice pushes full autonomy. That's wrong when the stakes are real. An agent ask for help loop knows when to stop guessing and pull in a human. Here's the teardown.August 25, 2026·9 min read
Agent Loop EngineeringState Machines vs Free-Form Agent LoopsWondering whether to let your agent roam free or lock it into defined states? An agent state machine trades flexibility for control. This case study shows when that trade pays off.August 25, 2026·9 min read
Agent Loop EngineeringHow to Cache Tool Results Across IterationsPicture your agent calling the same expensive API four times in one run for identical data. Agent loop tool caching kills that waste. Here's how to add a cache that speeds up loops without serving stale data.August 25, 2026·8 min read
Agent Loop EngineeringDeterministic vs Exploratory Loop ModesRunning the same input twice, one agent gave two different answers 40% of the time. A deterministic agent loop trades some flexibility for reproducibility you can actually debug. Here's how to switch modes.August 25, 2026·8 min read
Agent Loop EngineeringTemperature Settings Across Loop StepsAn agent set to temperature 0.9 for consistency invented a tool that didn't exist. Agent loop temperature isn't one setting — it should shift across steps. Here's the teardown.August 25, 2026·8 min read
Agent Loop EngineeringMeasuring Loop Efficiency: Steps to CompletionMost teams measure the wrong thing: they track average steps and miss the runs that actually hurt. Agent loop efficiency metrics done right look at the tail, not the mean. Here's a real reckoning.August 25, 2026·8 min read
