Recording Pentest Engagement

Name: recording-pentest-engagement
Author: jeremylongshore

Overview

A penetration test produces a lot of artifacts: scan outputs in multiple formats, screenshots showing the state of vulnerable pages, raw tool logs (nmap, Burp, custom scripts), the ROE and any amendments, exec-summary docs, and the findings themselves. Six months after the engagement closes, a question arises — sometimes benign ("can you remind me what we found?"), sometimes adversarial ("the customer claims we accessed an out-of-scope system; show us the logs"). The answer needs to be: "yes, here's the archive, and here's cryptographic proof it hasn't been touched since the engagement closed."

This skill packages the engagement directory into a single timestamped archive with a SHA-256 manifest covering every file. Optionally signs the manifest with GPG. The result is a portable, self-verifying record of what the engagement produced.

The skill also surfaces inconsistencies that would weaken the chain-of-custody claim: out-of-tree paths referenced in findings (meaning the finding refers to a file not actually in the archive), files in the directory not listed in the manifest, manifest entries whose hashes don't match. These are HIGH findings — they mean the archive is incomplete or has been modified after the fact, neither of which is acceptable for evidence purposes.

When the skill produces findings

Finding	Severity	Threshold	Affected control
File in tree not in manifest	HIGH	Found during walk; manifest entry missing	(evidence integrity)
Manifest entry hash mismatch	CRITICAL	Computed SHA-256 differs from manifest	(evidence integrity)
Manifest entry without file	HIGH	Manifest lists a path that doesn't exist	(evidence integrity)
Findings reference out-of-tree path	MEDIUM	A finding's `evidence` field points to a file not in the archive	(evidence completeness)
Symlink in tree	MEDIUM	Symlinks break archive portability and integrity	(evidence integrity)
Empty file in tree	INFO	0-byte file; possibly an export error	(operational)
Archive package complete	INFO	All checks pass	(positive confirmation)
Manifest signed	INFO	GPG signature present and valid form	(positive confirmation)

Prerequisites

Python 3.9+
An engagement directory laid out as recommended (see structure below)
Optional GPG installed for manifest signing

Instructions

Step 1 — Identify the engagement directory

python3 ./scripts/record_engagement.py engagements/acme-2026-q2/

The skill walks the directory recursively, builds a SHA-256 manifest, and produces a chain-of-custody report.

Step 2 — Run the packager

Options:

Usage: record_engagement.py PATH [OPTIONS]

Options:
  --output FILE              Findings output
  --format FMT               json | jsonl | markdown (default: markdown)
  --min-severity SEV         default info
  --manifest FILE            Manifest output path (default: PATH/manifest.sha256)
  --tar FILE                 Also create a .tar.gz archive at this path
  --sign                     Sign the manifest with GPG (uses default identity)
  --signer KEY               GPG key ID to sign with
  --exclude GLOB             Skip files matching glob (repeatable)

Step 3 — Verify the manifest

The skill emits a SHA-256 manifest in standard sha256sum format (one line per file: hash + two-space + path). The manifest is verifiable independent of the skill:

sha256sum -c engagements/acme-2026-q2/manifest.sha256

Anyone with access to the archive can run this check; if the output is "all OK," the archive is intact.

Step 4 — Sign the manifest (optional)

python3 ./scripts/record_engagement.py engagements/acme-2026-q2/ --sign

The skill shells out to gpg --detach-sign against the manifest, producing manifest.sha256.asc. Later verification:

gpg --verify manifest.sha256.asc manifest.sha256
sha256sum -c manifest.sha256

Both checks together: the manifest's contents match the archive, AND the manifest itself is signed by an identifiable party.

Step 5 — Create the portable archive (optional)

python3 ./scripts/record_engagement.py engagements/acme-2026-q2/ \
    --tar engagements/archives/acme-2026-q2.tar.gz

The tarball contains the engagement directory + manifest + signature. Hand the tarball to legal / archive / customer.

Examples

Example 1 — End-of-engagement closeout

python3 ./scripts/record_engagement.py engagements/acme-2026-q2/ \
    --sign \
    --tar engagements/archives/acme-2026-q2.tar.gz \
    --output engagements/acme-2026-q2/chain-of-custody.md

Example 2 — Daily snapshot during a long engagement

DATE=$(date +%Y%m%d)
python3 ./scripts/record_engagement.py engagements/acme-2026-q2/ \
    --manifest engagements/acme-2026-q2/manifest-$DATE.sha256 \
    --output engagements/acme-2026-q2/snapshot-$DATE.md

Daily snapshots build a time-series of the engagement's state which can be useful in incident-investigation contexts.

Example 3 — Pre-handoff integrity check

# Customer claims the archive is incomplete; verify before disputing
python3 ./scripts/record_engagement.py engagements/acme-2026-q2/ --min-severity high

If exit code is 0, the archive is internally consistent.

Output

JSON / JSONL / Markdown per lib/report.py. Exit codes: 0 clean, 1 high/critical, 2 error.

Each Finding includes:

id — evidence::<issue>::<path>
severity — CRITICAL / HIGH / MEDIUM / INFO
category — evidence-chain
summary — what's wrong with the artifact
evidence — file path, expected hash, observed hash, manifest entry

Error Handling

Path doesn't exist → exits 2 with operational error.
Permission denied reading a file → emits HIGH finding, continues walking other files.
GPG not installed with --sign requested → emits HIGH finding, manifest written unsigned, exits 1.
GPG signing fails (no default identity, etc.) → emits HIGH finding, manifest written unsigned, exits 1.
tar command fails with --tar requested → manifest still written; archive creation failure surfaces as HIGH finding.
