surface

surface is a command for coding agents from elementalsouls/Claude-BugHunter. It costs 51 tokens per session (458 once invoked), scanned A, original, MIT.

A command that ranks the parts of a website or service most worth testing for security problems, using reconnaissance data and earlier testing records.

In plain words
What is it for?
Use it after reconnaissance to prioritize endpoints, APIs, and other possible entry points for security testing.
Why use it?
It reduces the time spent testing low-priority or already-covered areas by showing where to start and what to skip.

About the project

Claude Code Spec Workflow is a set of Claude Code commands and agents that organizes software work into documented stages for new features and bug fixes. It is for developers who want Claude Code to handle requirements, design, implementation, issue resolution, and verification through repeatable workflows, with the catalogue entries providing the associated commands and agents.

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 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

/surface

View the prioritized attack surface for a target.

What This Does

  1. Reads the recon manifest at recon/<target>/manifest.json (produced by cbh recon) — the deterministic ranking comes from cbh surface <target>
  2. Reads hunt memory for patterns and previously tested endpoints
  3. Layers engine/skill_map.py (surface → bug-class → skill) + ledger signal on top of the manifest's ranked_surface (P1/P2/Kill)
  4. Outputs P1 (start here), P2 (after P1), and Kill List (skip)

The manifest is the recon→hunt contract — see docs/recon-manifest.md. Run cbh surface <target> for the raw deterministic ranking.

Usage

/surface target.com

Prerequisites

Run /recon target.com first. If no recon data exists, you'll be prompted to run recon.

Output

ATTACK SURFACE: target.com
═══════════════════════════════════════

Priority 1 (start here):
1. api.target.com/v2/users/{id} — IDOR candidate
   Tech: Express + PostgreSQL | First seen 12 days ago
   Suggested: numeric ID swap on GET/PUT/DELETE

2. api.target.com/graphql — introspection enabled, 47 mutations
   Suggested: field-level auth check on sensitive mutations

Priority 2 (after P1):
1. cdn.target.com:8443/upload — file upload endpoint
   Suggested: extension bypass, magic bytes

Kill List (skip):
- static.target.com — CDN only
- docs.target.com — third-party hosted

Memory:
- Pattern from alpha.com (same tech): auth bypass via method override ($800)
- 3 endpoints tested in previous session, 5 remain
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.
