# Web Application Reconnaissance — Hub

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:

```bash
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.
