Performing Penetration Testing

Performing Penetration Testing

Overview

v3.0.0 of penetration-tester is a 25-skill pack. Each skill is narrow and heavy-hitter compliant (≥250 LOC scripts, ≥2 reference docs, 8-field SKILL.md frontmatter). This orchestrator routes user intent to the right combination of narrow skills.

The 25 skills group into 7 clusters:

• Cluster 0 — this orchestrator
• Cluster 1 (5 skills) — Network / transport
• Cluster 2 (4 skills) — Information disclosure
• Cluster 3 (6 skills) — Source-code static analysis
• Cluster 4 (4 skills) — Dependency analysis
• Cluster 5 (3 skills) — Engagement governance
• Cluster 6 (3 skills) — Reporting

Cluster 5 + 6 are the v3 additions versus v2. Cluster 5 runs BEFORE any scan and refuses to proceed if authorization is missing or scope is malformed. Cluster 6 runs AFTER scans and produces the deliverable artifacts (vulnerability report, OWASP coverage report, executive summary, chain-of-custody archive).

Instructions

The orchestrator's job is intent routing — given a user utterance, decide which of the 25 narrow skills to invoke and in what order. Four steps:

Step 1 — Parse the user intent

Match the utterance against the intent-routing table below. The leftmost matching row determines the routing. If no exact match, default to the cluster-1-4 governance-first sequence and pare back based on context.

Step 2 — Run authorization-first

Before any cluster 1-4 scan invocation, run confirming-pentest-authorization. If it emits any CRITICAL finding, HALT — do not invoke any scan skill. The user must resolve the authorization issue before proceeding.

Step 3 — Run the matched skills in order

Invoke each skill from the routing-table row, in the listed order. Each skill emits its findings as JSON/​JSONL/​markdown via lib/​report.py. Persist per-skill output into engagement/​findings/<skill>-<date>.jsonl so the cluster 6 skills can consume them.

Step 4 — Compose deliverables

After scan skills complete, run cluster 6 in sequence: mapping-findings-to-owasp-top10, then composing-vulnerability-report, then generating-executive-summary, then recording-pentest-engagement for the chain-of-custody archive.

Intent routing (the table)

When unsure which to invoke, prefer the governance-first sequence (authorization + scope) and add cluster-1-4 skills based on what the user described.

For a typical engagement, the orchestrator routes through:

Backward compatibility

The v2 monolithic scripts (security_scanner.py, dependency_auditor.py, code_security_scanner.py) remain in scripts/ as the underlying engine for the original v2 invocation patterns. The v3 narrow skills re-implement and extend that logic with the canonical lib/​finding.py schema and the shared lib/​report.py output module.

If a downstream user has scripted invocations of the v2 scripts, those still work. New work should use the narrow skills directly.

The orchestrator's old "Step 1 / Step 2 / Step 3" instructions in v2 are subsumed by the intent-routing table above. The v2 checks correspond to:

Prerequisites

Per-skill prerequisites are documented in each skill's SKILL.md. The shared module lib/ requires Python 3.9+ and the standard library only.

Optional tools used by individual skills:

• bandit (Python static-analysis backend, cluster 3)
• pip-audit (cluster 4 Python dependency audit)
• pipdeptree (cluster 4 transitive trace)
• gpg (cluster 5 evidence signing)
• npm (cluster 4 npm dependency audit)

Each skill emits a graceful INFO Finding when an optional dependency is missing and falls back to a degraded but functional mode where possible.

Authorization is non-negotiable

The orchestrator REFUSES to invoke cluster 1-4 skills until confirming-pentest-authorization has emitted no CRITICAL or HIGH findings against the ROE. The cost of running an authorized scan is delay until the ROE is verified. The cost of running an unauthorized scan is potential criminal liability under CFAA (US), Computer Misuse Act (UK), or equivalent foreign statutes.

For details on the legal framework + ROE structure, see confirming-pentest-authorization/​references/​THEORY.md.

Examples

Example 1 — Full engagement, end to end

User: "Run a full pentest on engagements/​acme-2026-q2/"

Orchestrator routes:

1. confirming-pentest-authorization --roe engagements/​acme-2026-q2/​roe.yaml
2. (if no CRITICAL findings) defining-pentest-scope --roe engagements/​acme-2026-q2/​roe.yaml
3. Cluster 1-4 skills against each in-scope target, emitting per-skill JSONLs into engagements/​acme-2026-q2/​findings/
4. mapping-findings-to-owasp-top10 engagements/​acme-2026-q2/
5. composing-vulnerability-report engagements/​acme-2026-q2/
6. generating-executive-summary engagements/​acme-2026-q2/
7. recording-pentest-engagement engagements/​acme-2026-q2/ --sign --tar ...

Example 2 — Ad-hoc header check

User: "Check security headers on https://app.acme.example"

Orchestrator routes:

1. confirming-pentest-authorization (operator must confirm authz; fast path for own-system testing)
2. checking-http-security-headers https://app.acme.example

Example 3 — Dependency audit

User: "Audit dependencies in /​path/​to/​project"

Orchestrator routes:

1. auditing-npm-dependencies /​path/​to/​project (if package.json present)
2. auditing-python-dependencies /​path/​to/​project (if Python project present)
3. (if either produced HIGH/​CRITICAL findings) tracing-transitive-vulnerabilities /​path/​to/​project --audit-input <previous output>

Output

The orchestrator's output is the COMPOSITION of the called skills' outputs. The canonical end-state deliverables of a full engagement:

• engagement/​findings/​all-with-owasp.jsonl — enriched unified findings
• engagement/​reports/​vulnerability-report.md — deep technical report
• engagement/​reports/​owasp-coverage.md — OWASP A0X rollup
• engagement/​reports/​executive-summary.md — C-level / board summary
• engagement/​manifest.sha256 (+ optional .asc) — chain-of-custody manifest
• engagement/<archive>.tar.gz — portable archive

Error Handling

The orchestrator delegates error handling to each invoked skill. Cluster 5 errors (missing ROE, missing scope) HALT the engagement. Cluster 1-4 errors (scanner missing, network unreachable) emit INFO findings and continue. Cluster 6 errors (missing source findings) emit HIGH operational findings and continue with a partial deliverable.

v3.0.0 release notes

Released 2026-06-03. Major changes:

• 25 narrow heavy-hitter skills replace the v2 3-script monolith
• New cluster 5 (engagement governance) and cluster 6 (reporting)
• Canonical lib/​finding.py + lib/​report.py schema across all skills
• disallowed-tools defense-in-depth for high-risk patterns (rm, curl, wget, .env edits)
• v2 scripts (security_scanner.py, dependency_auditor.py, code_security_scanner.py) preserved as backward-compatible scripts under scripts/

Migration: existing v2 invocations continue to work. New work should use the narrow skills directly. See the backward-compat table above for the v2 → v3 mapping.
