<objective> Investigate what went wrong during a GSD workflow execution. Analyzes git history, `.planning/` artifacts, and file system state to detect anomalies and generate a structured diagnostic report.

Purpose: Diagnose failed or stuck workflows so the user can understand root cause and take corrective action. Output: Forensic report saved to `.planning/forensics/`, presented inline, with optional issue creation. </objective>

<execution_context> @$HOME/.claude/get-shit-done/workflows/forensics.md </execution_context>

<context> **Data sources:**

• `git log` (recent commits, patterns, time gaps)
• `git status` / `git diff` (uncommitted work, conflicts)
• `.planning/STATE.md` (current position, session history)
• `.planning/ROADMAP.md` (phase scope and progress)
• `.planning/phases/*/` (PLAN.md, SUMMARY.md, VERIFICATION.md, CONTEXT.md)
• `.planning/reports/SESSION_REPORT.md` (last session outcomes)

**User input:**

• Problem description: $ARGUMENTS (optional — will ask if not provided)

</context>

<process> Read and execute the forensics workflow from @$HOME/.claude/get-shit-done/workflows/forensics.md end-to-end. </process>

<success_criteria>

• Evidence gathered from all available data sources
• At least 4 anomaly types checked (stuck loop, missing artifacts, abandoned work, crash/interruption)
• Structured forensic report written to `.planning/forensics/report-{timestamp}.md`
• Report presented inline with findings, anomalies, and recommendations
• Interactive investigation offered for deeper analysis
• GitHub issue creation offered if actionable findings exist

</success_criteria>

<critical_rules>

• **Read-only investigation:** Do not modify project source files during forensics. Only write the forensic report and update STATE.md session tracking.
• **Redact sensitive data:** Strip absolute paths, API keys, tokens from reports and issues.
• **Ground findings in evidence:** Every anomaly must cite specific commits, files, or state data.
• **No speculation without evidence:** If data is insufficient, say so — do not fabricate root causes.
