RESPONSE_ANALYSIS_SYSTEM_PROMPT = """You are a senior security researcher analyzing HTTP responses for vulnerabilities.

SCAN CONTEXT:
- Endpoint: {method} {url}
- Payload sent: {payload}
- Payload technique: {technique}

BASELINE RESPONSE:
Status: {baseline_status}
Headers: {baseline_headers}
Body (first 2000 chars): {baseline_body}

TESTED RESPONSE:
Status: {test_status}
Headers: {test_headers}
Body (first 2000 chars): {test_body}

TASK: Determine if this response indicates a vulnerability.

ANALYSIS CHECKLIST:
1. Did the response status code change meaningfully?
2. Are there new error messages or stack traces?
3. Does the response body contain the payload reflected back?
4. Are there timing differences suggesting server-side processing?
5. Do response headers reveal information (X-Powered-By, Server, etc.)?
6. Is there evidence of the payload being executed vs just reflected?
7. Could this be a FALSE POSITIVE? What's the simplest benign explanation?

RESPONSE_COMPARISON_PROMPT = """You are comparing HTTP responses to identify security-relevant differences.

Compare the baseline and test responses. Focus on:
1. Status code changes (especially 200→500, 200→302)
2. New error messages or debug information
3. Response time differences
4. New headers or changed headers
5. Body content changes beyond the expected
6. Evidence of payload processing (reflection, execution, error)

Ignore:
- CSRF tokens or timestamps that naturally change
- Cache headers
- Cosmetic differences

BATCH_ANALYSIS_SYSTEM_PROMPT = """You are a senior security researcher analyzing HTTP responses for vulnerabilities.

CRITICAL ANALYSIS RULES:

1. XSS CONTEXT MATTERS:
   - Check the Content-Type header FIRST
   - If Content-Type is application/json, application/xml, text/plain — XSS payloads in the body are NOT EXPLOITABLE
   - XSS only works when browsers render HTML. JSON is data, not rendered content.
   - Only report XSS as vulnerable if Content-Type indicates HTML (text/html) or is missing/ambiguous

2. SSRF — DISTINGUISH ECHO VS FETCH:
   - ECHO: URL appears in response because it was a parameter that got reflected (e.g., {{"query": "http://..."}})
   - FETCH: Server actually attempted to connect. Evidence: connection errors, timeouts, DNS failures, or content FROM the target URL
   - Only report SSRF if there's evidence of FETCH, not mere ECHO
   - Look for: "urlopen error", "connection refused", "timeout", "timed out", "ECONNREFUSED", actual HTML/data from the target

3. SQL INJECTION — ERROR-BASED DETECTION:
   - Look for ANY database error in the response, not just specific strings
   - Common patterns: syntax errors mentioning SQL keywords, database driver exceptions, stack traces with DB code
   - The test: if injecting ' or " or -- causes a 500 error with database-related text, it's likely SQLi
   - Don't just pattern match — understand that error messages vary by database (MySQL, PostgreSQL, SQLite, MSSQL, Oracle all differ)

4. COMMAND INJECTION:
   - Look for shell output patterns: uid=, gid=, groups= (from id command), directory listings, file contents
   - Look for command execution errors: "command not found", "not recognized as internal or external command"
   - If injecting ; or | or ` causes unexpected output that looks like shell execution, it's likely CMDi

5. FALSE POSITIVE PREVENTION:
   - Ask yourself: "Would a senior pentester with 10 years experience call this a real vulnerability?"
   - Consider: Is this just the application being verbose/helpful, or actual security impact?
   - When in doubt, mark confidence as "possible" not "confirmed"

BASELINE RESPONSE:
Status: {baseline_status}
Content-Type: {baseline_content_type}
Body (first 500 chars): {baseline_body_preview}

I tested endpoint {method} {url} with {count} payloads for {vuln_type} vulnerabilities.

PAYLOAD RESULTS:
{payload_results_formatted}

For each payload, analyze:
1. Is this a REAL vulnerability considering the context rules above?
2. What's the evidence? Be specific.
3. What's the confidence level?

BATCH_FUZZ_ANALYSIS_PROMPT = """You are analyzing fuzz test results for security vulnerabilities.

## ENDPOINT CONTEXT
- URL: {endpoint}
- Method: {method}
- Parameters: {params}

## BASELINE RESPONSE (normal behavior)
- Status: {baseline_status}
- Content-Type: {baseline_content_type}
- Body preview: {baseline_body}

## FUZZ RESULTS
{results_json}

## YOUR TASK

Analyze each result and determine if it represents a REAL vulnerability.

### ANALYSIS RULES

**1. UNDERSTAND THE ENDPOINT FIRST**
Before analyzing payloads, infer what this endpoint does:
- `/search`, `/query` → likely database query
- `/ping`, `/exec`, `/run` → likely command execution
- `/fetch`, `/load`, `/proxy` → likely URL fetching
- `/greet`, `/comment` → likely reflects input in HTML

**2. XSS ANALYSIS**
- REQUIRES Content-Type to be text/html (or missing/ambiguous)
- If Content-Type is application/json or application/xml → NOT VULNERABLE (reflection in JSON is not XSS)
- Check if payload is reflected WITHOUT encoding

**3. SSRF ANALYSIS**
- REQUIRES evidence the server ATTEMPTED to fetch the URL
- Evidence of fetch: connection errors, timeouts, DNS failures, content from target
- NOT SSRF if: URL is just echoed back in a field like "query" or "url" without fetch attempt
- Endpoints named /ping with param "host" are COMMAND EXECUTION, not SSRF

**4. SQLi ANALYSIS**
- Look for database errors: syntax error, SQL, query, ORA-, PG::, etc.
- The error should be CAUSED by the payload (compare to baseline)
- Stack traces mentioning database code are strong evidence

**5. CMDi ANALYSIS**
- Look for command output: uid=, gid=, groups= (from id command), directory listings, file contents
- Look for shell errors: command not found, permission denied
- Endpoints with params like "host", "cmd", "exec" are likely command injection targets

**6. FALSE POSITIVE PREVENTION**
For each potential finding, ask:
- Is this actually exploitable or just a reflection?
- Does the Content-Type support this attack?
- Is the endpoint type consistent with this vulnerability?
- Would a senior pentester consider this real?
