enum-web

enum-web is a skill for Claude Code, Codex from thapr0digy/skills. It costs 39 tokens per session (14,353 once invoked), scanned A, original, MIT.

A web-application security assessment skill for testing websites and APIs. An API is a defined way for software to exchange data; the skill also checks login controls, settings, technology choices, and compliance with web-security standards.

In plain words
What is it for?
Use it with `/enum-web [target-url]` to review authentication, application and API behavior, configuration, discovered technologies, and web-security controls.
Why use it?
It helps assess whether a web application protects accounts, data, configuration, and API access against common security problems.

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

enum-web scanned grade A with 2 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 3d 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.

Sends data to an external URLlowData exfiltration

A POST to an outside endpoint may be telemetry or may be exfiltration; either way the mod talks to somewhere, and you should know where.

--arg command "HTTP_STATUS=$(curl -sk -X POST \"$GRAPHQL_URL\" -H \"Content-Type: application/json\" -d \"$INTROSPECTION_QUERY\" -w \"%{http_code}\" -o \"$GRAPHQL_OUT\" 2>/dev/null)" \

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

Makes network callslowCapability

Not a fault in itself. Listed so you know the mod talks to something, and to what.

/enum-web — Web Application Security Assessment

You are conducting comprehensive security assessment of web applications and APIs to evaluate security controls, identify vulnerabilities, and validate compliance with web security standards. Your goal is to analyze application security configurations, authentication mechanisms, and defensive measures using systematic assessment methodologies.


Step 1: Resolve Active Engagement

Run the engagement resolver block verbatim before any other logic.

# --- 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")
ASSESSOR=$(whoami)

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

After this block, $ENGAGEMENT_ID, $OUTPUT_DIR, and $ASSESSOR are guaranteed set and valid. If the resolver fails for any reason, stop and tell the user to run /pentest-init.


Step 2: Parse Arguments and Determine Targets

Accepted input

  • URL — e.g., https://app.acme.com or http://10.0.0.1:8080
  • No argument — fall back to most recent active recon output
ARG="${1:-}"

if [ -n "$ARG" ]; then
  WEB_TARGETS=("$ARG")
elif ls "${OUTPUT_DIR}/recon/active-"*.json > /dev/null 2>&1; then
  RECON_FILE=$(ls -t "${OUTPUT_DIR}/recon/active-"*.json | head -1)
  echo "No URL specified — reading web services from $RECON_FILE"
  # Extract hosts with web ports from the most recent active recon output
  WEB_TARGETS_JSON=$(jq '[.hosts[] | {ip, hostnames, ports: [.ports[] | select(.category == "web")]} | select(.ports | length > 0)]' "$RECON_FILE" 2>/dev/null)
  if [ -z "$WEB_TARGETS_JSON" ] || [ "$WEB_TARGETS_JSON" = "[]" ]; then
    echo "No web services found in $RECON_FILE. Provide a URL: /enum-web <url>" >&2
    exit 1
  fi
  # Build URL list from recon data
  mapfile -t WEB_TARGETS < <(echo "$WEB_TARGETS_JSON" | jq -r '.[] | .ip as $ip | .ports[] | (if .tls then "https" else "http" end) + "://" + $ip + ":" + (.port | tostring)')
else
  echo "No URL provided and no active recon data found." >&2
  echo "Provide a URL: /enum-web <url>" >&2
  exit 1
fi

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.

enum-web is a skill published in the GitHub repository thapr0digy/skills (2 stars, last pushed 3mo ago), licensed MIT. It adds 39 tokens to every session and 14,353 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 2 findings (sends data to an external url, makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
