pentester-enum-services

A setup guide for the first information-gathering phase of a penetration test. This phase identifies reachable ports, services, operating-system clues, and related public information about an authorized target.

In plain words
What is it for?
Use it to print the phase-one scan plan, render environment settings, run service and port enumeration, and validate the phase summary.
Why use it?
It gives scans a defined plan and records their outputs consistently. This makes later testing decisions based on known services rather than guesses.

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

pentester-enum-services 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 2d 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

enum-services

Procedure: .agents/phases/01-intelligence.md

Parallelism: Phase 1 long scans (nmap full/UDP, multi-target enum) run as subagents under the main orchestrator — Task List + no short timeout. See root AGENTS.md (Phase-internal parallelism) and ROLE.md §6–7. Schema product paths still apply. Schema: phase 1 in schema.json

# Sole plan entry (Schema CLI)
node .agents/schema/validate-target-schema.js --print-plan 1 \
  --id ${ID} --host ${SCAN_HOST} --scan-env docker|host-kali

# Env / Evidence keys only
node .agents/schema/env-render.js --scan-env docker|host-kali --id ${ID} --host ${SCAN_HOST}
  • Outputs / forbidden / summary keys: schema.json only
  • web_ports non-empty → Phase 1b
  • End: validate-target-schema.js ${ID} --strict-summary --stamp-chain
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.

pentester-enum-services is a skill published in the GitHub repository fb0sh/pentester (23 stars, last pushed 1mo ago), licensed MIT. It adds 63 tokens to every session and 303 once invoked, about $0.0003 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.
