# Intel agent stuck in a CAPTCHA loop on a news aggregator site

## TL;DR
A CAPTCHA loop on the aggregator means the site is sure the client is automated and will keep challenging it. There is no legitimate way through for a script, and trying harder only confirms the verdict. Detect the CAPTCHA on first sight, mark the aggregator defended, and move news intake to its feeds, its API, or a licensed news provider.

## The error
```text
(agent stuck)
intel agent stuck in captcha loop on news aggregator site; challenges repeat indefinitely
```

## When this helps
- an agent loops on aggregator CAPTCHAs
- news intake hits challenge pages
- marking defended aggregators
- hardening fetch layers

## When it doesn't
- you want to solve the CAPTCHAs; use the feeds instead
- no feed or API exists; the aggregator is out of reach
- CAPTCHA-solving services are on the table; take them off, they violate terms

## Works with
Any HTTP client and feed parser. CAPTCHA behavior is site-side.

## Steps
### 1. Detect the CAPTCHA on first sight and abort the fetch
```python
def has_captcha(html):
    return "captcha" in html[:5000].lower()
print("first-sighting abort; the loop never forms")
```
Expected: A detector. One sighting ends the fetch; the agent never sees the second challenge.

### 2. Mark the aggregator defended
```python
import json
reg = json.load(open("sources.json"))
reg["https://YOUR-aggregator/"] = {"status": "captcha-defended"}
json.dump(reg, open("sources.json", "w"), indent=2)
print("marked defended; no future run loops here")
```
Expected: A registry mark. The defense is learned once.

### 3. Move intake to feeds or a licensed provider
```bash
curl -s -A "IntelBriefingBot/1.0" "https://YOUR-aggregator/feed" -o agg.xml -w "HTTP %{http_code}\n"
python3 -c "import feedparser; print("feed entries:", len(feedparser.parse("agg.xml").entries))"
```
Expected: Feed entries. The aggregator's machine channels stay open where HTML is defended.

### 4. Guard every fetch against challenge pages
```python
def fetch_ok(status, body):
    t = body[:3000].lower()
    return status == 200 and "captcha" not in t
print("guard installed across the agent's fetch layer")
```
Expected: A fetch guard. Defenses anywhere in the pipeline now degrade gracefully.

## Other ways people phrase this
### captcha loop news aggregator site
First-sighting abort. Mark defended. Re-source.

### agent stuck aggregator captcha
The loop is the agent's bug; the CAPTCHA is the site's defense.

### news aggregator challenge loop
Feeds and APIs are the intended machine channels.

## Why it happens
CAPTCHAs are access controls, and repeated challenges mean the site will not admit the client. Automation cannot legitimately pass, by design. News aggregators syndicate through feeds and APIs meant for machines; the defended HTML is not the product.

## Edge cases
- Per-path defenses vary; mark at the URL level.
- Challenge HTML cached as news poisons briefings; validate before storing.
- A newly defended aggregator may reflect IP reputation; check the crawl pattern.
- Licensed news APIs are the durable answer for ongoing needs.
- A CAPTCHA that appears mid-session after successful fetches can mean the IP warmed into a blocklist; cool down the crawl rate.
