hacker-bob: Skill for Claude Code

.claude/skills/bob-status/SKILL.md

bob-status is a skill for Claude Code from vmihalis/hacker-bob. It costs 20 tokens per session (1,687 once invoked), scanned A, original, Apache-2.0.

A read-only command that reports the current state of a Hacker Bob security-evaluation session. It shows wave progress, findings, verification details, and grade summaries.

In plain words
What is it for?
Use it to inspect the latest session or a named target, check what to do next, and view stored status information at a glance.
Why use it?
It lets you see where an evaluation stands without changing its state, writing reports, or running new scans.

This is vmihalis/hacker-bob's own configuration. It tells Claude Code how to work on hacker-bob 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 hacker-bob configures →

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-status 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 7d 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.

How it starts

The opening of the file, as written. The whole thing — 108 lines — stays where its author put it; the contents beside it link to each section on GitHub.

You are Bob's read-only session status command. Give the operator a compact answer about where a Hacker Bob run stands and what command to run next. This is not a debug review.

Input: $ARGUMENTS (--last, no args, or <target_domain>)

Hard Rules

  • Read-only only. Never call mutating MCP tools, never write files, never merge waves, never transition phases, never update auth, never write reports, and never use HTTP scan or browser/target interaction tools.
  • Do not use Task.
  • Do not inspect Claude transcripts. Use /bob-debug --deep for transcript-backed root-cause analysis.
  • Keep the final answer short enough to read at a glance.

Argument Handling

  • No args or --last: inspect the latest local session under ~/hacker-bob-sessions.
  • <target_domain>: inspect that specific session directory.
  • If multiple non-flag tokens are present, stop and ask for one target domain.

Latest-session detection must pick the newest target directory by pipeline-events.jsonl mtime. If no pipeline event file exists, fall back in order to state.json, grade.json, report.md, then directory mtime.

Read Order

First, read the passive update cache if the helper is installed:

node "${CLAUDE_PROJECT_DIR:-$PWD}/.claude/hooks/bob-update.js" status "${CLAUDE_PROJECT_DIR:-$PWD}" --json

This command must only read the local update cache. Do not run network update checks from /bob-status.

After resolving target_domain, call:

bob_read_pipeline_analytics({ target_domain, include_events: false, limit: 20 })
bob_read_session_summary({ target_domain })
bob_read_state_summary({ target_domain })
bob_wave_status({ target_domain })
bob_read_verification_context({ target_domain })

If a read returns an authority error, report it as a session-integrity blocker. Do not treat the supplied target_domain as sufficient authority, and do not inspect or repair raw state.json; session-bound MCP tools must authorize against the initialized session record. Legacy sessions may default presentation or progress fields, but missing or drifted authority fields fail closed for tools that rely on them.

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.

bob-status is a skill published in the GitHub repository vmihalis/hacker-bob (97 stars, last pushed 8d ago), licensed Apache-2.0. It adds 20 tokens to every session and 1,687 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
