Bug Report Deduplicator
Bug triage automation workflow built with Langflow that deduplicates new bug reports against backlogs, links related issues, and suggests fixes from previously resolved bugs.

This Langflow flow streamlines bug triage by turning a noisy stream of incoming reports into structured, actionable decisions. It evaluates each new bug report against your existing backlog, detects likely duplicates, links related issues, and proposes a fix direction based on how similar bugs were resolved in the past. The outcome is faster triage, fewer redundant investigations, and more consistent handling of recurring defects across product releases.
How it works
This Langflow flow implements an issue triage and deduplication pipeline for bug reports.
The workflow starts by ingesting a new bug report (title, description, steps, environment, and optional logs). The system normalizes the text, extracts key signals (component area, suspected root cause, error messages, reproduction steps), and produces a structured representation that is comparable across reports.
A retrieval stage searches an indexed bug backlog (tickets, incident notes, and resolved issues) to find the most similar items. Similarity can be driven by embeddings and semantic search so the system can match reports even when wording differs.
A deduplication decision layer scores candidate matches and classifies the report as duplicate, related, or novel. For duplicates, it recommends linking to the canonical ticket and suggests metadata updates (labels, affected versions, severity signals). For related issues, it creates linkage recommendations to preserve context and prevent fragmented investigations.
For fix proposals, the flow retrieves resolution notes from similar closed bugs and synthesizes a suggested fix approach. The output is grounded in retrieved historical context, so recommendations reflect what previously worked and highlight when evidence is missing.
Finally, structured output components format the results into a consistent triage payload that can be pasted into issue trackers or used as an automated comment: matched ticket links, confidence rationale, recommended actions, and a proposed fix summary.
Example use cases
• QA teams can automatically detect when a new report is a duplicate of an existing ticket, reducing backlog clutter and improving prioritization accuracy.
• Support engineering can link customer-reported issues to known bugs quickly by retrieving similar historical tickets and suggested canonical links.
• Engineering leads can accelerate triage during incidents by grouping related reports and surfacing likely root causes from prior resolved defects.
• Product teams can maintain higher-quality bug backlogs by enforcing consistent linking, labeling, and structured triage notes across releases.
• Open-source maintainers can reduce duplicate GitHub issues by automatically suggesting existing issues and proposed next steps to reporters.
The flow can be extended to integrate directly with your issue tracker and raise the quality of triage decisions. Add connectors for Jira, Linear, or GitHub Issues to fetch backlogs, write comments, auto-link duplicates, and apply labels. Store structured ticket metadata (component, platform, version, stack trace hashes) to improve matching precision. For stronger governance, add thresholds and review gates so only high-confidence duplicates are auto-closed, while medium-confidence matches are routed to humans. You can also implement an incremental indexing pipeline to keep embeddings fresh and include release notes or changelog context to detect regressions and cluster bugs by release.
