Reliability & compatibility
Declared compatibility
Compatibility is declared by the source manifest. End-to-end runtime verification is coming, see below.
We're building live execution health for every listing: tool-call success rate, median latency, uptime, and last-checked timestamps, measured, not self-reported. It isn't live yet, so we don't show numbers we can't stand behind.

Perseus Report (Phase 4)
Context & Authorization
IMPORTANT: This skill generates a professional security report for the user's own codebase. The report is intended to help developers and stakeholders understand and remediate security issues in their own software.
Multi-Language Support
Report generation adapts remediation guidance based on detected language/framework:
| Language | Frameworks | |----------|------------| | JavaScript/TypeScript | Express, Fastify, Next.js, Nest.js | | Go | Gin, Echo, Fiber, Chi | | PHP | Laravel, Symfony, Slim | | Python | FastAPI, Django, Flask | | Rust | Actix-web, Axum, Rocket | | Java | Spring Boot, Quarkus | | Ruby | Rails, Sinatra | | C# | ASP.NET Core |
Overview
This skill executes the Reporting Phase of the Perseus framework. It synthesizes findings from Scan, Audit, Exploit, and Specialist phases into a professional executive report.
Goal: Communicate verified risks effectively to stakeholders and drive remediation.
Methodology:
- Collect: Gather all deliverables from previous phases.
- Verify: Prioritize verified exploits over theoretical risks.
- Contextualize: Explain business impact, not just technical flaws.
- Remediate: Provide language-specific, actionable fixes for each finding.
Execution Instructions
Step 1: Collect All Deliverables
Read all files in deliverables/:
Core Phase Deliverables:
engagement_profile.md(Mode, scope, constraints)code_analysis_deliverable.md(Scan)- All
*_analysis.mdfiles (Audit) exploitation_report.md(Exploit)verification_scope.md(Verification limits and approved window)
Specialist Deliverables (if present):
api_security_analysis.md(API + GraphQL + WebSocket + OAuth)injection_deep_analysis.md(NoSQL + SSTI + Log4j)crypto_security_analysis.md(JWT + Hashing + Encryption)supply_chain_analysis.md(CVEs + Typosquatting)file_security_analysis.md(Path Traversal + XXE + Zip Slip)business_logic_analysis.md(Race Conditions + AI Security)client_side_analysis.md(React/Vue/Angular + SSR)config_security_analysis.md(Docker + CI/CD + Cloud + K8s)
Step 2: Calculate Risk Metrics
Severity Scoring (CVSS-inspired):
| Severity | Criteria | Score | |----------|----------|-------| | Critical | RCE, Auth Bypass, SQLi with data access, Admin takeover, Container escape, AI prompt injection leading to RCE | 9.0-10.0 | | High | Stored XSS, SSRF to internal, Privilege Escalation, Sensitive data exposure, CI/CD injection, Public cloud storage | 7.0-8.9 | | Medium | Reflected XSS, CSRF, Information disclosure, Missing security headers, Outdated dependencies, Docker misconfig | 4.0-6.9 | | Low | Minor info leak, Best practice violations, Verbose errors, License issues | 0.1-3.9 |
Exploitability Factor:
- VERIFIED: Multiply by 1.0 (confirmed exploitable)
- POTENTIAL: Multiply by 0.7 (likely exploitable)
- THEORETICAL: Multiply by 0.4 (needs specific conditions)
Confidence Factor:
- High: Multiply by 1.0
- Medium: Multiply by 0.75
- Low: Multiply by 0.5
Verification Context Factor:
- VERIFIED in
PRODUCTION_SAFE: Multiply by 1.0 - VERIFIED in
STAGING_ACTIVE: Multiply by 0.9 - VERIFIED in
LAB_FULL: Multiply by 0.85 - VERIFIED in
LAB_RED_TEAM: Multiply by 0.8 POTENTIAL-PROD-BLOCKED: Multiply by 0.7
