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
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

SkillSpector: 3 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 | $0.00017 | $0.01835 |
| Opus 5.5 | $0.00007 | $0.00734 |
| Sonnet 5.5 | $0.00003 | $0.00367 |
| Haiku 4.5 | $0.00002 | $0.00184 |
Grade A, and why
cors-credential-wordpress 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 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.

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

CORS Credential WordPress Skill
Detect, confirm, and exploit CORS credential reflection on WordPress REST API endpoints. CORS misconfiguration is one of the most common critical findings in US SMB WordPress sites (~7-8% of all WP targets), enabling cross-origin data exfiltration with victim cookies. Documents 8 CORS variants and full browser PoC construction.
When to Use
- After
wp-mass-reconflags a target withAccess-Control-Allow-Credentials: true. - Testing any WordPress site's REST API for cross-origin data access.
- Building attack chains: CORS → user enumeration → spear-phishing → ATO.
- Validating whether a CORS finding is exploitable (not just present).
Prerequisites
- curl and python3.
web_extractorbrowser_navigatefor browser PoC verification.- Target must have WordPress REST API accessible (
/wp-json/wp/v2/).
How to Run
# Quick detection
curl --max-time 30 --connect-timeout 10 -skI "https://TARGET/wp-json/wp/v2/users" -H "Origin: https://evil.com" | grep -iE "access-control"
# Full CORS matrix (10 endpoints)
for ep in "users" "posts" "pages" "media" "comments" "categories" "tags" "settings" "plugins" "themes"; do
echo "=== /wp-json/wp/v2/$ep ==="
curl --max-time 30 --connect-timeout 10 -skI "https://TARGET/wp-json/wp/v2/$ep" -H "Origin: https://evil.com" | grep -iE "access-control|http/"
echo ""
done
Quick Reference
| Variant | Detection | Exploitability |
|---|---|---|
| Origin reflection + creds | Access-Control-Allow-Credentials: true + mirror Origin |
Critical — full data theft |
| Null origin | Access-Control-Allow-Origin: null |
High — sandboxed iframes |
| Wildcard no creds | Access-Control-Allow-Origin: * (no creds) |
Info — public data only |
| Credentialed preflight | OPTIONS returns 200 + ACAC | High — if GET without preflight |
| Auth-only leak | CORS only on auth-protected endpoints | High — cookie theft |
| Multi-origin | Multiple origins reflected | Critical — broader attack surface |
| Plugin-specific CORS | CORS only on plugin namespace | Medium — plugin data |
| Staging-only CORS | Production has no CORS, staging does | Medium — dependent on staging access |
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.

cors-credential-wordpress is a skill published in the GitHub repository uphiago/recon-skills (1,319 stars, last pushed 1mo ago), licensed MIT. It adds 17 tokens to every session and 1,835 once invoked, about $0.0001 per session on Opus 5.5. 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 2026-08-30.
