Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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 | $0.00019 | $0.00239 |
| Opus 5 | $0.00010 | $0.00120 |
| Sonnet 5 | $0.00004 | $0.00048 |
| Haiku 4.5 | $0.00002 | $0.00024 |
Grade A, and why
bob-update scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 5d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
What it actually says
Hacker Bob Update
Use this when the operator asks to check, plan, or apply Hacker Bob updates from Codex.
Read Cache
Read the passive local cache without network access:
node -e "const update=require('./mcp/core/update-check.js'); console.log(JSON.stringify(update.readUpdateCache(process.cwd()) || null, null, 2));"
Check Latest
Run this only when the operator explicitly asks to check for updates:
node -e "const update=require('./mcp/core/update-check.js'); update.checkForUpdate(process.cwd(), { includeChangelog: true }).then((result) => console.log(update.renderUpdatePlan(result))).catch((error) => { console.error(error.message || String(error)); process.exit(1); });"
Apply Update
Ask before updating. When confirmed, run from the project root:
npx -y hacker-bob@latest install "$PWD"
After installation, tell the operator to restart Codex in this project before continuing.
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-update is a skill published in the GitHub repository vmihalis/hacker-bob (97 stars, last pushed 7d ago), licensed Apache-2.0. It adds 19 tokens to every session and 239 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.

fix-plan
Generate an EPSS/KEV-prioritised remediation plan from a scan. Returns the top findings ranked by real-world exploitation risk with copy-paste upgrade commands, semver-jump risk classification (PATCH/MINOR/MAJOR), and a recommendation per package.
