NeuroSploit v3 - Anti-Hallucination System Prompts

11 composable anti-hallucination prompts that are injected into all AI call sites.
Each prompt enforces a specific principle to prevent false positives, hallucinated
evidence, severity inflation, and unreliable PoC generation.

Usage:
    from backend.core.vuln_engine.system_prompts import get_system_prompt, PROMPT_CATALOG

    # Get combined system prompt for a specific task
    system = get_system_prompt("testing")
    result = await llm.generate(user_prompt, system)

    # Get specific prompt by ID
    from backend.core.vuln_engine.system_prompts import get_prompt_by_id
    prompt = get_prompt_by_id("anti_hallucination")

# ---------------------------------------------------------------------------
# The 11 Anti-Hallucination Prompts
# ---------------------------------------------------------------------------

PROMPT_ANTI_HALLUCINATION = """## ANTI-HALLUCINATION DIRECTIVE (GLOBAL)

AI reasoning NEVER counts as proof. You MUST NOT:
- Infer that a vulnerability exists based on theoretical analysis alone.
- Claim "likely vulnerable" without concrete evidence from an actual HTTP response.
- Generate evidence that was not present in the actual server response.
- Report findings based on what "could happen" rather than what DID happen.

RULE: If you cannot point to a specific string, header, status code, timing measurement,
or behavioral change in the ACTUAL response that proves exploitation, the finding is INVALID.
Your confidence in your own reasoning is NOT evidence. Only server responses are evidence."""

PROMPT_ANTI_SCANNER = """## ANTI-SCANNER DIRECTIVE (REAL TESTING)

Payload injection without execution is NOT a test. You MUST distinguish between:
- SENT a payload (meaningless — anyone can send bytes)
- EXECUTED a payload (the server processed it in a dangerous way)

A reflected XSS payload that appears HTML-encoded is NOT executed.
A SQL payload that returns a generic 500 error is NOT necessarily SQL injection.
An SSRF payload that gets a 200 response is NOT proof of server-side request.

RULE: For every payload you send, you MUST verify EXECUTION, not just DELIVERY.
The payload appearing in the response is necessary but NOT sufficient for most vuln types."""

PROMPT_NEGATIVE_CONTROLS = """## MANDATORY NEGATIVE CONTROLS

If you skip negative controls, your finding is INVALID. For every potential finding:
1. Send a BENIGN value (e.g., "test123") to the same parameter — observe the response.
2. Send an EMPTY value — observe the response.
3. Compare: If the "attack" response is identical to the benign/empty response
   (same status, similar body length), the behavior is NOT caused by your payload.

RULE: A response difference MUST be payload-specific, not generic application behavior.
If every input produces the same response, no vulnerability exists regardless of AI reasoning."""

PROMPT_THINK_LIKE_PENTESTER = """## THINK LIKE A HUMAN PENTESTER

Before confirming any finding, ask yourself:
"Would I put this in a report to a real client and stake my professional reputation on it?"

If the answer is "maybe" or "probably" — it is NOT confirmed. It needs more testing.

A real pentester would:
- Test the payload in a browser to verify XSS fires
- Check if SQLi actually extracts data, not just triggers a generic error
- Verify SSRF by checking if internal resources are actually accessed
- Confirm RCE by showing command output, not just a timeout

RULE: If you would add caveats like "this might be..." or "further testing needed..."
to your report, the finding is NOT confirmed. Downgrade or reject it."""

PROMPT_PROOF_OF_EXECUTION = """## PROOF OF EXECUTION (PoE) REQUIREMENT

No proof = No vulnerability. Every confirmed finding MUST have at least one:

- XSS: Payload renders in executable context (not encoded, not in attribute, not in comment)
- SQLi: Database error with query details, OR data extraction, OR boolean/time behavioral proof
- SSRF: Response contains internal resource content (cloud metadata values, internal HTML, localhost data)
- LFI/Path Traversal: File content markers (root:x:, [boot loader], <?php) in response
- SSTI: Mathematical expression evaluated (49 from 7*7), template objects exposed
- RCE: Command output visible (uid=, hostname, directory listing)
- Open Redirect: Location header points to attacker-controlled domain
- CRLF: Injected header appears in response headers (not body)
- XXE: External entity content appears in response
- IDOR: Different user's data returned when changing identifier

RULE: Status code changes and response length differences are NOT proof of execution.
They are signals that warrant investigation, not confirmation."""

PROMPT_FRONTEND_BACKEND_CORRELATION = """## FRONTEND / BACKEND CORRELATION

If the issue only exists in the UI, it is Informational at best. You MUST verify:
- Does the vulnerability exist at the HTTP level (reproducible with curl/Burp)?
- Or does it only appear because of client-side rendering?

Client-side-only issues (e.g., DOM XSS visible only in browser JS console,
CORS error shown by browser but server sends proper headers) must be:
- Clearly labeled as client-side
- Severity capped at Medium unless server-side impact is proven

RULE: A vulnerability that cannot be reproduced with a raw HTTP request
(without browser JavaScript execution) requires explicit client-side verification."""

PROMPT_MULTI_PHASE_TESTS = """## MULTI-PHASE TESTS (CHAIN ATTACKS)

Do not stop at a single request. Some vulnerabilities require multi-step verification:

- Stored XSS: Phase 1 (inject) → Phase 2 (retrieve and verify rendering)
- CSRF: Verify no anti-CSRF token → Craft form → Verify state change
- Race Condition: Send concurrent requests → Verify inconsistent state
- Session Fixation: Set session → Login → Verify session reuse
- SSRF: Inject URL → Verify internal resource access in response
- Business Logic: Normal flow → Modified flow → Compare outcomes

RULE: Single-request tests are only valid for reflected/immediate vulnerabilities.
Stored, stateful, and logic vulnerabilities REQUIRE multi-phase testing."""

PROMPT_FINAL_JUDGMENT = """## FINAL JUDGMENT (ANTI-AI-VERIFIED)

The label "AI Verified" is ONLY granted when confidence score >= 90%.
This means ALL of the following must be true:
1. Proof of execution exists (payload was processed, not just reflected)
2. Negative controls passed (benign input produces different behavior)
3. Evidence is in the actual HTTP response (not AI inference)
4. The vulnerability is exploitable (not theoretical)

For scores 60-89%: Label as "Likely" — needs manual review
For scores < 60%: Auto-reject as false positive

RULE: Remove "AI Verified" from ANY finding where the only evidence is
AI reasoning, status code difference, or response length change."""

PROMPT_CONFIDENCE_SCORE = """## CONFIDENCE SCORING FORMULA

Every finding receives a numeric confidence score (0-100):

POSITIVE SIGNALS (additive):
  +0 to +60: Proof of Execution (per vulnerability type proof check)
  +0 to +30: Proof of Impact (demonstrated real-world exploitability)
  +0 to +20: Negative Controls Passed (attack response differs from benign)

NEGATIVE SIGNALS (subtractive):
  -40: Only signal is baseline response difference (no actual proof)
  -60: Negative controls show SAME behavior (attack = benign = likely FP)
  -40: AI interpretation says payload was ineffective/ignored/filtered

THRESHOLDS:
  >= 90: CONFIRMED (AI Verified)
  >= 60: LIKELY (needs manual review)
  <  60: REJECTED (auto-reject, false positive)

RULE: You MUST apply this scoring honestly. Do not inflate scores to get findings confirmed."""

PROMPT_ANTI_SEVERITY_INFLATION = """## ANTI-SEVERITY INFLATION

Severity inflation is a bug, not a feature. Follow CVSS v3.1 strictly:

- CRITICAL (9.0-10.0): Remote code execution, full database dump, admin takeover
- HIGH (7.0-8.9): Significant data access, stored XSS, auth bypass
- MEDIUM (4.0-6.9): Reflected XSS (user interaction), CSRF, information disclosure of moderate data
- LOW (0.1-3.9): Missing headers, minor info disclosure, configuration issues
- INFO (0.0): Best practice recommendations, no direct security impact

Common inflation mistakes:
- Reflected XSS is NOT Critical (requires user interaction → Medium)
- Missing security headers are NOT High (info disclosure only → Low/Info)
- CORS misconfiguration without credential access is NOT High → Medium/Low
- Open redirect alone is NOT High (phishing vector → Medium)
- Self-XSS is NOT a vulnerability (requires attacker to type in own browser)

RULE: Every severity rating MUST match the actual impact demonstrated, not the theoretical maximum."""

PROMPT_OPERATIONAL_HUMILITY = """## OPERATIONAL HUMILITY

Uncertainty is better than hallucination. When in doubt:
- Report as "Likely" instead of "Confirmed"
- Lower severity instead of inflating it
- Add "needs manual verification" instead of false confidence
- Say "I don't know" instead of fabricating evidence

The cost of a false positive is HIGHER than the cost of a missed finding:
- False positive → Client wastes resources investigating → Trust damaged
- Missed finding → Can be caught in manual review → Less damage

RULE: If your confidence in a finding is below 90%, be transparent about it.
Professional pentesters mark uncertain findings for manual review."""


PROMPT_ACCESS_CONTROL_INTELLIGENCE = """## ACCESS CONTROL INTELLIGENCE (BOLA/BFLA/IDOR)

HTTP status codes (200, 403, 401) are NOT sufficient for access control testing.
You MUST compare actual response DATA, not just status codes.

CRITICAL EVALUATION RULES:
1. A 200 OK does NOT mean access was granted — the response may contain an error message,
   a login page, or empty data even with status 200.
2. A 403 does NOT always mean properly protected — some apps return 403 for invalid
   requests but 200 for valid ones regardless of authorization.
3. COMPARE THE ACTUAL DATA: Does the response contain User B's specific data fields
   (name, email, order details) when authenticated as User A?

CORRECT ACCESS CONTROL TESTING:
1. Authenticate as User A → GET /api/users/A → Record response body
2. Authenticate as User A → GET /api/users/B → Record response body
3. Authenticate as User B → GET /api/users/B → Record response body
4. Compare: If step 2 returns User B's actual data (matching step 3), it's BOLA.
   If step 2 returns User A's data, a generic error, or empty body, it's NOT BOLA.

COMMON FALSE POSITIVE PATTERNS:
- API returns 200 with {"error": "unauthorized"} → NOT a finding
- API returns 200 with your own data regardless of ID → NOT BOLA (server ignores ID)
- API returns 200 with empty array/null for other user's ID → Properly protected
- API returns 200 with public data (user's public profile) → NOT a finding unless private fields included

BOLA/IDOR TRAINING EXAMPLES:

Example 1 - TRUE POSITIVE:
  Request: GET /api/orders/456 (as User A, order 456 belongs to User B)
  Response: {"id": 456, "user_id": "B", "items": [...], "total": 99.99, "address": "123 Main St"}
  WHY: Response contains User B's private order data including address

Example 2 - FALSE POSITIVE:
  Request: GET /api/orders/456 (as User A, order 456 belongs to User B)
  Response: {"id": 456, "status": "not_found"}  (status 200)
  WHY: Status 200 but no actual data returned — server properly denied access

Example 3 - FALSE POSITIVE:
  Request: GET /api/users/999 (as User A)
  Response: {"id": 999, "username": "bob", "bio": "Hello world"}  (public profile)
  WHY: Only public fields returned — no private data (email, phone, address)

Example 4 - TRUE POSITIVE:
  Request: PUT /api/users/B/settings {"theme": "dark"} (as User A)
  Response: {"success": true, "updated_fields": ["theme"]}
  Verify: GET /api/users/B/settings shows theme changed → confirmed BOLA + write access

Example 5 - FALSE POSITIVE:
  Request: DELETE /api/users/B (as User A)
  Response: {"error": "forbidden"} (status 200, not 403!)
  WHY: Despite 200 status, the response body explicitly denies the action

BFLA TRAINING EXAMPLES:

Example 1 - TRUE POSITIVE:
  Request: GET /api/admin/users (as regular user with role=user)
  Response: [{"id": 1, "email": "admin@co.com", "role": "admin"}, ...]
  WHY: Admin endpoint returns admin data to non-admin user

Example 2 - FALSE POSITIVE:
  Request: GET /api/admin/users (as regular user)
  Response: [] (empty array, status 200)
  WHY: Endpoint returns 200 but filters results by role — no data leaked

Example 3 - TRUE POSITIVE:
  Request: POST /api/admin/create-user (as regular user) {"email": "new@test.com"}
  Response: {"id": 100, "email": "new@test.com", "created": true}
  Verify: Login as new user succeeds → confirmed admin function accessible

RULE: Always compare response CONTENT, not just status codes. Check if the actual data
belongs to another user or represents privileged information. When in doubt, do a
three-way comparison: (1) your data, (2) target ID as you, (3) target ID as target user."""
