Recon Skills is a pack of security-testing skills covering reconnaissance, web applications, APIs, authentication, vulnerability validation, cloud infrastructure, and reporting. Security professionals use it for authorized assessments of systems they own or have written permission to test. The catalogue entries are individual skills from the pack.
Getting it into your agent
It runs from inside its repository, so the clone comes first — what it calls does not travel with the file alone.

SkillSpector: 41 findings, up to high
These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00042 | $0.13597 |
| Opus 5 | $0.00021 | $0.06799 |
| Sonnet 5 | $0.00008 | $0.02719 |
| Haiku 4.5 | $0.00004 | $0.01360 |
Grade A, and why
wstg-web-pentest scanned grade A 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 7d 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.

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

WSTG Web Application Pentest
Full OWASP WSTG-aligned testing methodology. Each phase maps to a WSTG category and provides concrete commands, expected outputs, pitfalls, and verification criteria.
The 12 phases:
1. Information Gathering WSTG-INFO
2. Configuration & Deployment WSTG-CONF
3. Identity Management WSTG-IDNT
4. Authentication WSTG-ATHN
5. Authorization WSTG-ATHZ
6. Session Management WSTG-SESS
7. Input Validation WSTG-INPV
8. Error Handling WSTG-ERRH
9. Weak Cryptography WSTG-CRYP
10. Business Logic WSTG-BUSL
11. Client-side WSTG-CLNT
12. API Testing WSTG-APIT
Classify every observation:
| State | Meaning |
|---|---|
| Signal | Observation justifies follow-up |
| Exposed | Service or behavior reachable in tested context |
| Vulnerable | Security property failed under controlled test |
| Exploitable | Controlled test demonstrated concrete impact |
When to Use
- Starting a web application pentest with a defined scope
- Auditing a web application against the OWASP testing standard
- Building a test plan from observed technology and behavior
- When the engagement requires methodology documentation
- Converting automated scanner output into validated findings
Prerequisites
- In-scope domains, IPs, APIs, and test accounts
- Exclusions, rate limits, test windows, and abort conditions
- Permitted actions: passive, active read-only, intrusive, destructive
- Tools installed:
curl,subfinder,dnsx,httpx,katana,nuclei,nmap,ffuf,jq,python3,openssl,tlsx,wappalyzerorwhatweb - Browser with intercepting proxy configured for authenticated testing
- Test accounts for two distinct identities (for authorization testing)
How to Run
TARGET="example.com"
OUTPUT_DIR="${OUTPUT_DIR:-./output}/${TARGET}"
mkdir -p "$OUTPUT_DIR"/{assets,http,urls,evidence,reports}
# Run phases sequentially, stopping at scope boundaries:
# 1. INFO -> 2. CONF -> 3. IDNT -> 4. ATHN -> 5. ATHZ ->
# 6. SESS -> 7. INPV -> 8. ERRH -> 9. CRYP -> 10. BUSL ->
# 11. CLNT -> 12. APIT -> Report
What this file has done since we first saw it
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.

wstg-web-pentest is a skill published in the GitHub repository uphiago/recon-skills (1,254 stars, last pushed 9d ago), licensed MIT. It adds 42 tokens to every session and 13,597 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 1 finding (makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-03.
