Introduction
When an application goes down, engineers need more than an error message. They need context: what happened during previous incidents, which approaches were tried, and what the team learned from those experiences.
In many development environments, valuable incident knowledge remains scattered across logs, documentation, and individual engineers' experiences. When a similar problem appears again, engineers may have to repeat parts of the investigation.
This is one of the challenges we wanted to address with RecallOps, a memory-first AI-assisted incident recovery application.
As part of the RecallOps team, my contribution focused on Hindsight and AI memory integration. This work helped us explore how persistent memory can support incident investigation and make previously recorded knowledge accessible when new incidents occur.
Why AI memory matters in incident response
Traditional incident management systems help teams record incidents, track their status, and document resolutions. However, storing information and making it useful during a future investigation are two different challenges.
An incident record may contain useful details, but engineers still need a way to discover relevant information when they encounter a related issue.
AI memory offers a way to connect information from previous investigations with the incident being analyzed now.
For example, imagine that an engineer is investigating a timeout in an inventory API. Previously recorded information about network connectivity or connection pool exhaustion may provide useful investigative context.
However, a similar symptom does not prove that the underlying cause is the same. Historical information should support investigation, not replace verification.
This idea became an important part of our approach to RecallOps.
Introducing Hindsight into RecallOps
RecallOps uses Hindsight Cloud as its persistent memory layer.
Hindsight provides memory capabilities that allow applications to retain information and retrieve relevant memories later. We used these capabilities to connect past incident knowledge with the current investigation workflow.
My contribution focused on the Hindsight and AI memory integration aspect of the project.
The overall workflow connects incident information from the RecallOps application to Hindsight, allowing relevant memories to be recalled during incident analysis.
This gives the application a way to work with information beyond the incident currently open on the dashboard.
The integration is designed to support two key activities:
Retaining useful knowledge: Incident observations and engineer-confirmed outcomes can be stored as memories, allowing the application to preserve context from previous investigations.
Recalling relevant information: When an engineer analyzes a new incident, the application can retrieve related memories and present them as evidence for review.
Together, these capabilities form the memory foundation of RecallOps.
From stored information to useful evidence
Persistent memory is useful only when engineers can understand how retrieved information relates to the incident they are investigating.
RecallOps connects Hindsight retrieval with its incident analysis workflow. The application can display retrieved evidence and associated suggestions, helping engineers inspect the context behind an investigation lead.
Consider a synthetic example involving a payment gateway with high latency. A previously recorded observation describes an exhausted outbound connection pool.
When a related incident is analyzed, this historical information may provide a possible investigation direction.
But what happens if the current incident involves a different service?
RecallOps is designed to distinguish direct historical references from cross-service references and general infrastructure knowledge. A memory associated with one service should not automatically be presented as a verified resolution for another.
This distinction matters because AI-assisted incident response needs to communicate uncertainty clearly.
The engineer must still investigate the current environment, verify the relevant evidence, and determine whether a suggested approach is appropriate.
Learning from both successful and unsuccessful approaches
Incident knowledge should not be limited to successful resolutions.
An unsuccessful troubleshooting attempt can also be valuable because it records what was tried and what did not help.
RecallOps supports a workflow in which engineers explicitly confirm investigation outcomes. The application can then retain the recorded outcome as part of its persistent memory.
This creates a feedback loop:
- An engineer reports an incident.
- RecallOps retrieves relevant historical memories.
- The engineer reviews evidence and investigates.
- The engineer confirms the outcome.
- The outcome can be retained for future investigations.
The purpose of this workflow is to make previous experience available when similar problems arise.
It does not mean that the system automatically learns a guaranteed fix or independently resolves production incidents. Human review remains central to the process.
Challenges and lessons
Working on Hindsight and AI memory integration highlighted an important distinction between retrieving relevant information and establishing that information is correct for the current situation.
A memory may be related to a symptom without being applicable to the affected service. A historical resolution may have depended on conditions that no longer exist.
For this reason, evidence and context are essential.
The project also reinforced the importance of treating external memory as part of a larger application workflow rather than as an isolated feature.
Memory retention, retrieval, incident analysis, and engineer-confirmed outcomes need to work together for the overall experience to be useful.
I gained experience exploring AI memory capabilities and their role in building applications that can use previously recorded knowledge to support future tasks.
What's next?
RecallOps is an ongoing project. Future improvements could include evaluating retrieval quality across a wider range of incident scenarios, organizing memories more effectively, and making evidence relevance easier for engineers to assess.
We also want to continue improving how the application communicates uncertainty and distinguishes historical context from verified findings.
Our goal is to help engineering teams preserve useful knowledge and make it easier to access during incident investigation.
