pentest-cleanup is a skill for Claude Code from thapr0digy/skills. It costs 38 tokens per session (2,735 once invoked), scanned B, original, MIT.

A checklist generator for closing an authorized penetration-testing engagement. It reads the activity log to identify items placed on target systems during testing.

In plain words
What is it for?
Use it to produce removal and verification commands for cleanup; it does not execute those commands.
Why use it?
It helps ensure deployed tools, accounts, tunnels, persistence methods, and other test artifacts are removed and verified.

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 B, and why

pentest-cleanup scanned grade B with 1 finding 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 2mo 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.

Reaches for credential filesmediumPrivilege escalation

SSH keys, cloud credentials, git-credentials, .npmrc, /etc/shadow: reading these is how a config file becomes a credential leak.

| SSH authorized_keys entry | `sed -i '/<key fingerprint>/d' ~/.ssh/authorized_keys` | `cat ~/.ssh/authorized_keys` |

Downgraded: this mod is about security review, or the phrase is quoted, so it is likely naming the pattern rather than instructing it.

/pentest-cleanup — Engagement Cleanup

Generate a cleanup checklist for engagement end. Parse activity log to identify every artifact deployed on target systems — tools uploaded, persistence mechanisms, accounts created, tunnels, web shells. Produce checklist with removal + verification commands. You do NOT execute any removal commands.


Step 1: Resolve Active Engagement

Use the Bash tool to read the active engagement pointer and extract required fields:

# --- Engagement Resolver ---
ENGAGEMENT_JSON=$(cat ~/.pentest/active-engagement 2>/dev/null)

if [ -z "$ENGAGEMENT_JSON" ]; then
  echo "No active engagement found. Run /pentest-init or /pentest-switch." >&2
  exit 1
fi

if [ ! -f "$ENGAGEMENT_JSON" ]; then
  echo "Active engagement path '$ENGAGEMENT_JSON' does not exist. Run /pentest-switch." >&2
  exit 1
fi

ENGAGEMENT_ID=$(jq -r '.engagement_id' "$ENGAGEMENT_JSON")
OUTPUT_DIR=$(jq -r '.output_dir' "$ENGAGEMENT_JSON")
TESTER=$(whoami)

TESTER_MATCH=$(jq -r --arg h "$TESTER" '.testers[] | select(.handle == $h) | .handle' "$ENGAGEMENT_JSON")
if [ -z "$TESTER_MATCH" ]; then
  echo "Operator '$TESTER' is not registered on this engagement." >&2
  exit 1
fi
# --- End Engagement Resolver ---

After this block, $ENGAGEMENT_ID, $OUTPUT_DIR, and $TESTER are guaranteed to be set and valid.


Step 2: Parse Activity Log for Artifacts

Use the Bash tool to extract all completed exploit and post-exploit entries from the activity log:

jq -r 'select(.action == "post_exploit" or .action == "exploit") | select(.status == "completed") | [.ts, .tester, .action, .target, .tool, .command] | @csv' "${OUTPUT_DIR}/activity.log"

Also read the loot directory index if present — some tool deployments are only traceable from loot entries (e.g., an LSASS dump implies procdump was uploaded):

ls -1 "${OUTPUT_DIR}/loot/" 2>/dev/null

For each log entry returned, classify the artifact using the following signal table:

Activity Log Signal Artifact Type
action == "exploit" and tool contains shell or webshell Web shell
action == "post_exploit" and tool contains chisel, ligolo, socat, or ssh Tunnel/proxy
action == "post_exploit" and details or command mentions persistence, cron, schtask, service, or registry Persistence
action == "post_exploit" and details or command mentions upload, transfer, or push Tool uploaded
action == "exploit" and details or command mentions account, user, or addcomputer Account created
action == "post_exploit" and details or command mentions firewall, iptables, or netsh Firewall change
