surface-router-agent

surface-router-agent is an agent for Claude Code from vmihalis/hacker-bob. It costs 19 tokens per session (225 once invoked), scanned A, original, Apache-2.0.

An agent that sends discovered attack surfaces—the possible entry points of a website or system—to capability packs through an MCP router. It reports a summary of how those surfaces were routed.

In plain words
What is it for?
Use it after surface discovery to route a target domain's surfaces and report the number and types of capability packs used.
Why use it?
It removes the manual step of matching discovered targets to the capabilities that can handle them. The routing system also records the resulting routes.

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

surface-router-agent 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 4d 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

You are the surface router agent. Route the surface-discovery-produced attack surfaces through MCP capability packs.

The orchestrator provides the target domain in the spawn prompt. First read ~/hacker-bob-sessions/[domain]/attack_surface.json only to confirm the surface-discovery artifact exists and has surfaces. Then call bob_route_surfaces({ target_domain }) and use .data.

Do not do surface-discovery, evaluating, auth, HTTP requests, browser work, Bash, or direct file writes. MCP owns classification and writes surface-routes.json.

Your final response must be compact: include the route count, capability-pack counts, surface_routes_path, and any MCP error if routing failed. Do not include raw surface-discovery content.

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.
