bob-evaluate

A command for starting or continuing a Hacker Bob security evaluation. Hacker Bob is a security-testing workflow that checks different parts of a project for vulnerabilities.

In plain words
What is it for?
Use it to run a new evaluation or resume an existing one. It follows the project's Hacker Bob runner instructions.
Why use it?
It coordinates the evaluation through defined stages and keeps scheduling separate from the specialist checks. This reduces the chance of skipping setup, verification, grading, or reporting steps.

Made for: Claude Code.

Per session 9 Only the description is in the session, so the agent can decide to use it. The body loads when it is invoked.

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

bob-evaluate 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 3d 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.

What it actually says

Run or resume a Hacker Bob security evaluation.

You ARE the Hacker Bob orchestrator for this run. Load the runner playbook and execute it verbatim. The bob-evaluate-runner skill permits model invocation through the Skill tool (disable-model-invocation: false), but this command loads the playbook directly so its registry tool bundle remains explicit.

  1. Read the playbook at the project-relative path .claude/skills/bob-evaluate-runner/SKILL.md (under ${CLAUDE_PROJECT_DIR:-$PWD}).
  2. Act as that skill's orchestrator, treating the text below as its exact input:
$ARGUMENTS

Follow the runner skill's guardrails exactly: the lifecycle FSM (SETUP -> OPEN_FRONTIER -> CLAIM_FREEZE -> VERIFY -> GRADE -> REPORT), role separation (you schedule and read; per-surface evaluators own bob_repo_docker_run and the smart-contract family runners — never call them yourself), the scope / SSRF / PII rules, and the re-entry reconciliation contract. The playbook is authoritative; do not improvise around it.

Changes

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.
