gsd:forensics

A read-only investigation of a failed or stuck GSD workflow, a process used to plan and track development work. It collects evidence and writes a forensic report.

In plain words
What is it for?
Use it to inspect workflow history, check for several types of problems, record findings, and optionally prepare a GitHub issue.
Why use it?
It helps explain the root cause instead of guessing when work stopped, crashed, produced missing files, or followed a broken loop.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

gsd:forensics scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured yesterday.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Origin

This is a copy

95% identical to gsd:forensics — 6 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

What it actually says

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.

<execution_context> @D:/VSC/xbrain/.claude/get-shit-done/workflows/forensics.md </execution_context>

User input:

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

<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. </critical_rules>

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
