# XC_VM Structured Code Review (Pragmatic Mode)
This repository uses a structured multi-agent review process.
Execution order is mandatory:
1. Architect
2. Security Auditor
3. Performance Analyst
4. Code Reviewer
5. Final Verdict
The system must:
- Assume untrusted input.
- Assume internet exposure.
- Assume production deployment.
- Avoid unrealistic theoretical attacks.
- Focus on practical, real-world risk.
Agents must:
- Avoid repeating findings.
- Clearly label severity: Low / Medium / High.
- Provide realistic mitigation steps.
- Avoid exaggerated conclusions.
- Avoid generic praise.
Output format is mandatory:
---
## 1. Architectural Analysis
...
## 2. Security Analysis
...
## 3. Performance Analysis
...
## 4. Code Quality Review
...
## 5. Final Verdict
- Overall Risk Level:
- Production Ready:
- Refactor Priority:
- Blocking Issues:

## Example finding template (required)
- **Title:** Short descriptive title
- **Files (path:line):** repo/path/file.php#L123
- **Severity:** Critical / High / Medium / Low
- **Confidence:** High / Medium / Low
- **Description:** One-paragraph clear description of the issue
- **Reproduction / PoC:** Steps or minimal input to reproduce (if applicable)
- **Impact:** What happens and why it matters
- **Suggested mitigation / patch:** Short actionable mitigation or code snippet
- **Suggested owner:** team or role responsible
Provide at least one concrete `suggested_patch` snippet (diff or commands) for every High or Critical severity finding.
## Severity matrix (guidance)
- **Critical:** Remote, unauthenticated exploit leading to full system compromise or license bypass; trivial to reproduce. (Use sparingly)
- **High:** Authenticated or easily reachable vulnerability allowing data exfiltration, RCE, privilege escalation, or financial/license bypass.
- **Medium:** Localized data exposure, logic flaws with constrained impact, or costly remediation but no immediate compromise.
- **Low:** Maintainability, style, minor misconfigurations, or unlikely edge-cases.
When assigning severity, include brief justification mapping to the matrix.
## Deduplication / ownership rules
- Agents must not repeat identical findings. If an agent finds the same issue another agent reported, it must cite the canonical finding using the "Files (path:line)" and add complementary context (e.g., exploit scenario, perf numbers, or architectural rationale).
- The first agent that reports a finding should be considered the canonical source; downstream agents must reference it like: "See finding: repo/path/file.php#L123 (Architect)" and then add only non-duplicate information.
- If two agents produce conflicting severities, the conflict must be recorded in the Final Verdict with both opinions and a recommended reconciled severity.
## Metadata to include in every finding (machine-parsable)
- title: string
- file: string (path#L)
- severity: Critical|High|Medium|Low
- confidence: High|Medium|Low
- owner: string
- suggested_patch: (optional) small diff or commands
Recommended format: include the above as a JSON code block at the end of each finding to aid automation. Example:
```json
{
"title": "SQL injection in getUser()",
"file": "src/auth/User.php#L210",
"severity": "High",
"confidence": "High",
"owner": "backend-team",
"suggested_patch": "patch.diff"
}
```
## Tools and artifacts (optional)
- Agents are encouraged to attach or reference automated artifacts when relevant: SAST output, linter snippets, benchmark graphs, flamegraphs, heap dumps, or small testcases.
- If external scanning tools are used, note the tool name and version and attach the raw output or a short excerpt.
## Examples and expectations
- Include one worked example (one High severity finding) in reviews produced by the system during onboarding runs to demonstrate the required level of detail and patch quality.
