Individual skill
recon-fallbacks
Class-level playbook for external recon when the standard Go/unix toolchain is unavailable — Python-equivalent probing, DNS resolution, port scanning, CMS/git-server fingerprinting, anonymous repo enumeration, and verified finding write-ups. Use alongside or instead of recon/web2-recon pipelines when binaries are missing or probing needs custom logic.

# RECON FALLBACKS — no-binary recon & verified reporting
## When to load
- `dnsx` / `httpx` / `naabu` / `dig` missing but Python3 present.
- Probing needs per-host logic the CLI tools can't express (redirect chains, generator meta, cookie names).
- Writing findings from recon output where auto-detection must be verified before claiming.
## 1. Identify WHICH httpx you have
`command -v httpx` succeeding proves nothing — the Python lib ships a CLI stub that dies on PD flags (`Error: No such option '-s'`). Test: `httpx -version >/dev/null 2>&1 && echo PD || echo not-PD`. If not-PD but `python3 -c "import httpx"` works, go in-process (§2).
## 2. Python probe matrix (httpx lib)
```python
import httpx, re, json, socket
client = httpx.Client(verify=False, timeout=8, follow_redirects=False,
