verdict-dfir: Instructions file for Claude Code

CLAUDE.md

verdict-dfir CLAUDE.md is an instructions file for Claude Code from TimothyVang/verdict-dfir. It costs 5,628 tokens per session, scanned A, original, Apache-2.0.

Repository instructions for VERDICT DFIR, a digital forensics and incident response application that examines evidence and produces an analyst report. They define its commands, result terms, read-only investigation tools, and signed Verdict output.

In plain words
What is it for?
Use them when running or maintaining VERDICT, investigating supported evidence, interpreting SUSPICIOUS, INDETERMINATE, and NO_EVIL results, or preparing its reports.
Why use it?
They prevent users and agents from treating a limited examination as proof that an entire environment is clean. They also provide a consistent operating contract for investigations and reports.

Instructions file for Claude Code

Written for Claude Code: $CLAUDE_PROJECT_DIR variable. Also seen: reads .claude/ paths; mentions CLAUDE.md; mentions Claude Code.

This is TimothyVang/verdict-dfir's own configuration. It tells Claude Code how to work on verdict-dfir itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything verdict-dfir configures →

Not installable: its command points at a path on the author’s own machine, so it runs nowhere else. The line is /home/sansforensics/....

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

verdict-dfir CLAUDE.md 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 2d ago.

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.

CLAUDE.md

This file is the Claude Code operating contract for VERDICT DFIR. It is public-release guidance for running and maintaining the application, not a private development diary.

What VERDICT Is

VERDICT is a DFIR agent that runs inside Claude Code. Point it at supported evidence and it opens a Case, drives the typed read-only MCP tool surface, verifies every Finding, and writes a signed Verdict plus analyst report.

Canonical one-shot path:

bash scripts/setup
scripts/verdict <path-to-evidence>

Interactive Claude Code path:

claude
# then type one of:
/verdict <path-to-evidence>
investigate <path-to-evidence>

Verdict words are strictly scoped:

  • SUSPICIOUS means VERDICT found reportable evidence.
  • INDETERMINATE means leads or limited coverage prevent a scoped clearance.
  • NO_EVIL means no reportable Finding in the artifacts actually examined. It is never a whole-environment clean bill of health.

VERDICT ecosystem — what is what

VERDICT is a local-first DFIR (digital forensics & incident response) agent platform, split into three repos:

Repo Role It is…
caseforge-core Headless controller: privacy routing, model selection, structured findings, custody validation, the caseforge CLI. the driver
verdict-opencode The agent runtime — a branded fork of opencode; the verdict binary is built from it. the engine
verdict-dfir-beta / this repo The forensic toolkit: findevil-mcp (Rust, 34 read-only tools) + findevil-agent-mcp (Python, 14 custody/crypto tools) + DFIR doctrine (agent-config/) + hash-chained custody. Consumed by caseforge via VERDICT_DFIR_HOME. the evidence lab (you are here)

Runtime flow: caseforge (controls + guards) → verdict binary (runs the agent) → this repo's findevil MCP tools (do the forensics) → hash-chained custody → caseforge verify.

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.
