Sub-skills under this directory:
| Sub-skill | Path | When to load |
|---|---|---|
| Discovery | load_skill("/skills/standard/recon/web-recon/discovery/SKILL.md") |
directory/file fuzzing, vhost, JS analysis |
| API enumeration | load_skill("/skills/standard/recon/web-recon/api-enumeration/SKILL.md") |
REST/GraphQL/parameter fuzzing |
| CMS scanning | load_skill("/skills/standard/recon/web-recon/cms-scanning/SKILL.md") |
WordPress/Joomla/Drupal detected |
| WAF detection | load_skill("/skills/standard/recon/web-recon/waf-detection/SKILL.md") |
proxy/CDN suspected |
| Auth mapping | load_skill("/skills/standard/recon/web-recon/auth-mapping/SKILL.md") |
login flow analysis |
| Cookie audit | load_skill("/skills/standard/recon/web-recon/cookie-audit/SKILL.md") |
sink behind session, race-condition recon |
Overall recon workflow, scope rules, and handoff format are loaded into your system prompt at agent boot — no load_skill call needed for them.
Tag-Driven Fast Paths
When the orchestrator passes challenge tags, skip straight to the matching sub-skill:
| Tag | First action | Sub-skill to load |
|---|---|---|
sqli |
Fire a single error-triggering payload on every form/param | /skills/standard/exploit/web/sqli/SKILL.md recon section |
ssti |
Probe every reflection point with {{7*7}} |
/skills/standard/exploit/web/ssti/SKILL.md recon section |
lfi |
Path-traversal probe on every file/path param | discovery.md |
idor |
Enumerate object IDs on every user-data endpoint | api-enumeration.md |
auth |
Map the full auth flow before other recon | auth-mapping.md |
HTTP Request Deduplication Pattern
When iterating parameters (IDs, pages, paths), always deduplicate via recon/probed.txt to avoid re-probing the same URLs after context summarization:
URL="http://<TARGET>/api/resource/$ID"
if grep -Fxq "$URL" recon/probed.txt 2>/dev/null; then
echo "SKIP: $URL"
else
echo "$URL" >> recon/probed.txt
curl -sS "$URL" -o /tmp/probe.html -w '%{http_code}\n'
head -10 /tmp/probe.html
fi
Resume rule: Before any scan loop, check tail -1 recon/probed.txt to find the last probed item and continue from there — not from the beginning.
Stop rule: If 5 consecutive probes return the same status code + same response size (±50 bytes), stop that enumeration axis and pivot to a different surface.
