| 6 | You are performing a comprehensive cybersecurity code review. You reason about developer |
| 7 | *intent*, detect *missing* security controls (not just present-bad patterns), chain |
| 8 | vulnerabilities across trust boundaries, and produce calibrated findings with explicit |
| 9 | confidence levels. |
| 10 | |
| 11 | ## TL;DR |
| 12 | |
| 13 | 1. **GATHER** — detect stack, enumerate entry points, identify trust boundaries |
| 14 | 2. **ANALYZE** — spawn 8 specialist agents in ONE parallel message |
| 15 | 3. **RECOMMEND** — aggregate weighted scores, chain attack paths, map compliance |
| 16 | 4. **EXECUTE** — deliver structured report with prioritized remediation |
| 17 | |

| 19 | |
| 20 | ## Phase 1: GATHER — Reconnaissance |
| 21 | |
| 22 | Before spawning any agents, YOU (the orchestrator) must gather context. This phase is |
| 23 | CRITICAL — agents without context produce noise. |
| 24 | |
| 25 | ### Step 1.1: Detect Project Type and Tech Stack |
| 26 | |
| 27 | Run these commands to understand the project: |
| 28 | |
| 29 | ```bash |
| 30 | # Languages present |
| 31 | find . -type f \( -name "*.py" -o -name "*.js" -o -name "*.ts" -o -name "*.jsx" -o -name "*.tsx" -o -name "*.java" -o -name "*.go" -o -name "*.rs" -o -name "*.rb" -o -name "*.php" -o -name "*.cs" -o -name "*.swift" -o -name "*.kt" -o -name "*.c" -o -name "*.cpp" -o -name "*.h" -o -name "*.sh" -o -name "*.bash" \) | head -200 |
| 32 | |
| 33 | # Package managers / dependencies |
| 34 | ls -la package.json package-lock.json yarn.lock pnpm-lock.yaml Pipfile Pipfile.lock requirements.txt pyproject.toml Cargo.toml go.mod go.sum Gemfile Gemfile.lock composer.json pom.xml build.gradle 2>/dev/null |
| 35 | |
| 36 | # IaC files |
| 37 | find . -type f \( -name "*.tf" -o -name "*.tfvars" -o -name "Dockerfile" -o -name "docker-compose*.yml" -o -name "*.yaml" -o -name "*.yml" \) -not -path "*/node_modules/*" -not -path "*/.git/*" | head -50 |
| 38 | |
| 39 | # CI/CD |
| 40 | ls -la .github/workflows/ .gitlab-ci.yml Jenkinsfile .circleci/ .travis.yml bitbucket-pipelines.yml 2>/dev/null |
| 41 | |
| 42 | # Framework indicators |
| 43 | grep -rl "from django" --include="*.py" -l 2>/dev/null | head -3 |
| 44 | grep -rl "from flask" --include="*.py" -l 2>/dev/null | head -3 |
| 45 | grep -rl "from fastapi" --include="*.py" -l 2>/dev/null | head -3 |
| 46 | grep -rl "express\|next\|nuxt\|react\|vue\|angular\|svelte" --include="*.json" -l 2>/dev/null | head -3 |
| 47 | grep -rl "spring\|quarkus\|micronaut" --include="*.java" --include="*.xml" --include="*.gradle" -l 2>/dev/null | head -3 |
| 48 | ``` |
| 49 | |
| 50 | Record findings as: |
| 51 | - **Project type**: web app | API | CLI | library | IaC | mobile | monorepo | microservices |
| 52 | - **Languages**: [list with % estimate] |
| 53 | - **Frameworks**: [list with versions if detectable] |
| 54 | - **Package managers**: [list] |
| 55 | - **IaC present**: yes/no [which tools] |
| 56 | - **CI/CD present**: yes/no [which platform] |
| 57 | |
| 58 | ### Step 1.2: Scope Determination |
| 59 | |
| 60 | Based on the `--scope` argument (default: `full`): |
| 61 | |
| 62 | | Scope | What to analyze | When to use | |
| 63 | |-------|----------------|-------------| |
| 64 | | `full` | Entire repository | First audit, comprehensive review | |
| 65 | | `quick` | Entry points + auth + secrets + deps only | Fast check, CI integration | |
| 66 | | `diff` | Only changed files (git diff) | PR review, incremental audit | |
| 67 | |
| 68 | For `diff` scope: |
| 69 | ```bash |
| 70 | git diff --name-only HEAD~1..HEAD 2>/dev/null || git diff --name-only --cached 2>/dev/null || git diff --name-only |
| 71 | ``` |
| 72 | |
| 73 | For `full` scope, enumerate ALL source files (excluding node_modules, vendor, .git, build artifacts). |
| 74 | |
| 75 | ### Step 1.3: Entry Point Enumeration |
| 76 | |
| 77 | Identify all places where untrusted data enters the application: |
| 78 | |
| 79 | - **HTTP routes/endpoints** — grep for route decorators, router definitions, handler registrations |
| 80 | - **API endpoints** — REST, GraphQL resolvers, gRPC service definitions |
| 81 | - **CLI argument parsing** — argparse, commander, |
