Structured debugging skill for methodical root cause analysis. Use when investigating bugs, unexpected behavior, or errors. Produces an issue summary, key findings, root cause analysis, and recommended solutions without modifying code.
Root cause analysis methods for PHP bugs. Provides 5 Whys technique, fault tree analysis, git bisect guidance, and stack trace parsing.
Stops execution and fixes root cause when commands, builds, scripts, or tools fail unexpectedly. Triggers on workaround language: 'directly', 'instead', 'alternatively', 'skip', 'fall back', 'work around', 'isn't working', 'broken', 'manually'. Activates on any unexpected non-zero exit code or process failure.
Identifies bugs, analyzes errors, performs root cause analysis, and proposes fixes
Deep analysis debugging mode for complex issues. Activates methodical investigation protocol with evidence gathering, hypothesis testing, and rigorous verification. Use when standard troubleshooting fails or when issues require systematic root cause analysis.
Reliable end-to-end engineering workflow for debugging, root-cause analysis, minimal patching, and verification in production codebases. Use when Codex needs to investigate a failure systematically, trace execution, test hypotheses, implement a correct fix, validate the resolution, and check for regressions before declaring the task complete.
DTC Full-Funnel Diagnosis & Attribution Engine —— Full-funnel attribution analysis, key indicator anomaly detection, cross-business-line problem localization, root cause analysis, priority ranking. Use when user mentions: 诊断, diagnose, 归因, attribution, 问题分析, root cause, 指标下降, conversion rate decline, ROAS decline, CPA increase, 全链路, full-funnel, 异常检测, anomaly, 问题出在哪, why the decline.
Diagnose a recurring failure (STUCK task, clustered CI error, frequent reverts) by dispatching sub-agents to digest CI logs without bloating main context. Returns one root-cause diagnosis.
You are an expert error analysis specialist with deep expertise in debugging distributed systems, analyzing production incidents, and implementing comprehensive observability solutions.
Use when working with debugging toolkit smart debug
Systematic debugging methodology with root cause analysis. Phases: investigate, hypothesize, validate, verify. Capabilities: backward call stack tracing, multi-layer validation, verification protocols, symptom analysis, regression prevention. Actions: debug, investigate, trace, analyze, validate, verify bugs. Keywords: debugging, root cause, bug fix, stack trace, error investigation, test failure, exception handling, breakpoint, logging, reproduce, isolate, regression, call stack, symptom vs cause, hypothesis testing, validation, verification protocol. Use when: encountering bugs, analyzing test failures, tracing unexpected behavior, investigating performance issues, preventing regressions, validating fixes before completion claims.
Execute provided command(s), capture failures, and summarize root cause and fixes. Use when asked to run a command and report errors.
