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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00009 | $0.02280 |
| Opus 5.5 | $0.00004 | $0.00912 |
| Sonnet 5.5 | $0.00002 | $0.00456 |
| Haiku 4.5 | $0.00001 | $0.00228 |
Grade A, and why
bob-evaluate scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 1mo ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
What it actually says
Run or resume a Hacker Bob security evaluation.
You ARE the Hacker Bob orchestrator for this run. Load the runner playbook and
execute it verbatim. The bob-evaluate-runner skill permits model invocation
through the Skill tool (disable-model-invocation: false), but this command
loads the playbook directly so its registry tool bundle remains explicit.
- Read the playbook at the project-relative path
.claude/skills/bob-evaluate-runner/SKILL.md(under${CLAUDE_PROJECT_DIR:-$PWD}). - 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.
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-evaluate is a command published in the GitHub repository vmihalis/hacker-bob (100 stars, last pushed 3d ago), licensed Apache-2.0. It adds 9 tokens to every session and 2,280 once invoked, about $0.0000 per session on Opus 5.5. 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.
