pentest-engagement
Run a professional penetration engagement OR a network vulnerability scan from a scope. WEB mode (apex domains / app URLs) — mandatory surface expansion, systematic OWASP attack-class coverage, reversible active exploitation, authoritative validation, Transilience PDF. NETWORK mode (a list of IPs/CIDRs, e.g. 1500 hosts) — machine-prudent BATCHED tool-first nmap sweep (host discovery + bounded common+less-common port/service scan + CVE surfacing) with a uniform per-IP output tree, then bounded deep-dives on the highest-value hosts. The general (non-CTF) analogue of hackthebox/htb-solve.

- Gen Agent Trust Hubwarn
The pentest-engagement skill automates security testing and vulnerability scanning. It accesses environment credentials, executes network discovery tools, and can transmit results to Slack. It also allows for custom reporting commands, which provides flexibility but represents a potential vector for command execution if input scope files are not strictly controlled.

What does this agent skill do?
Pentest Engagement
Orchestrates a scoped pentest end-to-end via the pentest-engagement workflow. It is the breadth-complete, coverage-gated counterpart to the flag-shaped htb-solve — same engine (coordinator-loop, now with interleaved per-finding validation built into the loop), but driven by an attack-class coverage matrix instead of a flag, with surface expansion and root-cause severity baked in.
When to use
A real (non-CTF) engagement defined by a scope — either:
- WEB — web / API / cloud apps defined by apex domains / asset URLs, or
- NETWORK — a list of IPs / CIDRs / ranges (e.g. 1500 hosts) to scan for live services and vulnerabilities.
The workflow auto-detects the mode in Setup (engagement_kind): predominantly IPs/CIDRs → network; apex domains / app URLs → web. For HackTheBox/CTF use hackthebox (htb-solve) instead.
Run it
WEB — from a scope file or inline:
Workflow('pentest-engagement', { scope_file: 'projects/pentest/<engagement>-scope.md' })
Workflow('pentest-engagement', { scope: { engagement_name, apex_domains:[], assets:[...], creds_env:[...], roe, business_tier } })
NETWORK — inline IP/CIDR list or a scope file containing one (a plain newline list of IPs/CIDRs is accepted):
Workflow('pentest-engagement', { targets: ['10.0.0.0/24', '192.0.2.0/24', '198.51.100.7'] })
Workflow('pentest-engagement', { scope_file: 'projects/pentest/<engagement>-ips.txt', scan_profile: 'standard' })
Options (shared): maxConcurrent (default = prudent, derived from CPU cores — ~half the cores, capped 2–8; never hundreds/thousands of parallel tasks), dryRun, max_experiments, business_tier, report (default true).
Options (network): scan_profile light (bounded 1-1024 + curated less-common, for large/fast sweeps) / standard (full-range -p- on every reachable host, DEFAULT; two-stage SYN→-sV on found-open ports, host-count-guarded, message-bus + non-443-TLS aware) / full (-p- + bounded UDP); udp (top-50 UDP; off for light/standard, auto-on for full); slice_size (hosts per scan worker, auto ≈64 IP-list / 2 CIDR-heavy); deepen_top (deep-dive the N highest-value hosts, default 10, 0 to skip); geo_vantages (≤2 gcp zones for the 2nd-vantage allowlist re-probe; overrides the US+EU default), auto_provision (default true; false = detect+flag only, no cloud spend). On a source-IP/geo-allowlist signature the workflow auto-provisions a 2nd-geography vantage and re-probes the filtered hosts before concluding "no surface."
Write the scope file per reference/scope-file-format.md. Credentials are referenced by env-var name only and read from the repo .env via python3 tools/env-reader.py — never inline secret values.
Phases (what the workflow does)
- Setup —
env-readercreds, parse scope, classify kind (web|network), read CPU cores → prudent parallel-task cap,OUTPUT_DIR = projects/pentest/<date>_<engagement>/, STARTED Slack (gated). - Expand (WEB, the #1 fix) — MANDATORY CT-log / passive-DNS / origin-discovery across every in-scope apex (
crt.sh,certspotter,subfinder, origin-discovery for CDN/WAF-fronted hosts). Scope = the discovered surface, not the handoff. Builds the per-asset work list + seeds each asset's coverage matrix. Scan (NETWORK, replaces Expand) — slice the IP/CIDR set into machine-prudent batches; one nmap worker per slice (agents scale with slices ≈ dozens, never with IP count) runs the SAME pipeline: host discovery (reachability is unknown) → bounded common+less-common port/service scan → CVE surfacing (nmap --script vulners,nuclei, each CVE-ID enriched viatools/nvd-lookup.py) → writes a uniform per-IP treehosts/<ip>/{recon,host.json,findings}+ a mergedrecon/inventory/. - Assess (single interleaved stage — no separate downstream validation pass) — WEB: each asset →
coordinator-loop(coverage mode), which validates each candidate the instant it is materialized on fresh blind agents (strict per-finding cure/drop loop) before search continues. NETWORK: boundedcoordinator-loopdeep-dives on only thedeepen_tophighest-value hosts, same interleaved per-finding validation (everything else is the uniform tool-scan, not a per-host agent). Coverage-by-VALID: a class is covered only by aVALID/REPAIREDfinding, a justified N/A, or a genuine negative — a class whose candidates were all rejected/dropped stayspendingand search keeps going. - Correlate —
attack-path-stitcher+risk-prioritiseracross all validated findings → ranked org roadmap. - Report (deterministic — no agent authors the report) — JS hands the resolved engagement block + exact commands to ONE finalize runner:
tools/report_data_build.pymerges the namespaced interim finding-JSONs into the canonicalreport_data.json(the sole-owner assembly), then the format-dispatched renderer runs —transilience→ the canonicalgenerate_report.pyPDF skill,custom→custom_report_cmd(or a Markdown fallback). JS then hard-gates:report_dataassembled ∧ (transilience:WROTE∧bytes>0∧ the[assets: …/formats/transilience-report-style]provenance tag), retry-once →BLOCKED. OnlyVALID/REPAIREDfindings appear (drop-entirely —validated/is confirmed-only by construction); REJECTED (false-positives/) and uncured DROPPED (dropped/) never appear and there is no gaps/assurance section. The finalize runner also runsnetwork_coverage_map.py(swept-host tail) +coverage_gate.pyover the whole engagement, writesreports/coverage-matrix.json, and the deliverable includes a deterministic Attack Pattern Coverage section (surface-unit × attack-class). COMPLETE is a hard 100% gate: it requires the report to assemble+render AND the coverage gate to reportcomplete:true(every applicable cell covered) — for BOTH web and network (network additionally requires scan-completion). Any untested applicable cell →INCOMPLETE_coverage/BLOCKED. - Package & deliver — a verified
<report_id>_deliverable.zip(reports/ input/ logs/ artifacts/), a short stats summary (summary.md: agents, findings by severity, elapsed; tokens/cost renderunavailable — no runtime token counter), and the workflow returnsslack_offer: true.
Post-run (main loop, outside the workflow): because coordinators must not call AskUserQuestion, the invoking agent shows the returned summary and asks whether to post the deliverable_zip to Slack; on yes, python3 tools/slack-send.py --channel "$PENTEST_SLACK_CHANNEL_ID" (gated on a successful, COMPLETE engagement).
Report options: report_format transilience (default) | custom; custom_report_cmd (the custom renderer, receives the report_data.json path + reports/ dir); prior_report (a prior PDF or report_data.json — its title/sector/scope are metadata-only, never seeding the work list) + version to mint the cover version + "Supersedes" line.
Determinism (be honest)
The decision layer is a frozen pure-JS computeVerdict (parity-guarded, fixture-pinned), its operands are frozen per engagement via NVD/KEV --cache-dir snapshots (artifacts/nvd-cache/, artifacts/kev-snapshot.json), and the adversarial quorum is raised to 3. Given identical inputs the verdict is provably identical. But a fresh live run is highly reproducible, not 100% — LLM sampling produces the booleans/numbers that feed the verdict, and live-target drift moves the inputs; that ceiling is inherent and stated plainly, not papered over. Byte-identical results are a guarantee 100% only on replay of a frozen evidence set (the Phase-2 replay cache, artifacts/validation-cache/) — that is the sole context in which "same request → same result" is a guarantee rather than a strong tendency.
Boundaries
- Orchestrator only — never run the coordinator loop inline; the coverage/bookkeeping discipline needs the workflow boundary.
- A missing credential is not a global block — the unauthenticated surface is always tested; only a no-reachable-asset scope blocks.
- Reversible own-org/own-tenant writes are authorized by default (create-then-delete is non-destructive); destructive ops, DoS, brute force, and out-of-scope tenants are prohibited (set in RoE).
