What problem does it solve? Debugging reported bugs requires manually correlating issue reports, source code, and production logs, which is slow and error-prone. This Skill structures that investigation end-to-end so you reach a root cause faster. ## Core Features & Use Cases - Issue Intake: Fetches the GitHub Issues bug report and comments, then extracts symptoms, scoping identifiers, and a time window. - Code Path Tracing: Greps the source tree for error messages and feature names, traces the call chain from controller to data layer, and collects every log statement along the way. - Tiered Log Queries: Runs scoped grep queries against local logs in three tiers (error overview, specific message templates, chronological entity trace) and cross-checks external dependency failures. - Use Case: A user reports that game verification fails intermittently. Provide the issue ID, and the Skill reads the report, traces the verification endpoint code, queries the last two days of logs filtered by the game ID, and produces a structured root cause report with a recommended fix. ## Quick Start Investigate the bug reported in GitHub issue 3922115 and produce a root cause analysis report.
