How to Handle Partial Failures Inside the Loop

What happens when one tool call in a batch fails but the rest succeed? Handling agent loop partial failure well is the difference between a resilient agent and one that dies on a hiccup.

Checkpointing Agent State Between Iterations

Agent loop checkpointing saves the agent's state each iteration so a crash costs one step, not the whole run. Here's how to checkpoint what matters, cheaply, without slowing the loop.

Interrupting and Resuming an Agent Loop

Most agents can't be paused — kill one mid-task and its work is gone. Building a pause resume agent loop takes one design change. Here's the fragile version and the resumable fix.

Streaming Intermediate Steps From the Loop

An agent sat silent for forty seconds and users assumed it had frozen — and left. Streaming agent loop steps to the UI fixed the abandonment overnight. Here's the case and the how-to.

How to Log Every Step of the Agent Loop

Most agent loop logging is useless — walls of text nobody reads until something breaks. Here's how to log an agent so you can actually debug it, with a structured schema that pays off.

Sequential vs Parallel Tool Execution in Agents

When should an agent run tools in parallel and when must it wait? Getting parallel vs sequential tool calls wrong either wastes time or corrupts results. Here's how to decide, with code.

Tool Call Batching Inside the Loop

Agent tool call batching lets the model request several tools at once instead of one per turn. Here's a slow one-at-a-time loop, why it drags, and the batched version that runs 3x faster.

Scratchpads and Working Memory in the Agent Loop

Agents with a scratchpad solve multi-step problems a scratchpad-less agent can't, even on the same model. Here's how agent scratchpad memory works and a case where it doubled success.

How to Summarize History Mid-Loop Without Losing State

An agent summarized its own history mid-run and forgot it had already booked the flight — then booked it again. Good agent loop history summarization keeps state intact. Here's how.

Context Compaction Between Agent Turns

Most advice on agent context compaction is backwards: it compresses on a timer and loses the wrong things. Here's how to compact by relevance, keep what matters, and do it safely.

Managing the Context Window Across Loop Iterations

Why does your agent get slower and dumber the longer it runs? The agent loop context window is filling with junk. Here's a bloated loop, why it degrades, and how to keep context lean.

Tree of Thoughts Inside the Agent Loop

A tree of thoughts agent explores several reasoning paths and keeps the best, instead of committing to the first. Here's a real case where branching turned a stuck agent into a solver.
