API Security Testing Workflow

Overview

Specialized workflow for testing REST and GraphQL API security including authentication, authorization, rate limiting, input validation, and API-specific vulnerabilities.

When to Use This Workflow

Use this workflow when:

  • Testing REST API security
  • Assessing GraphQL endpoints
  • Validating API authentication
  • Testing API rate limiting
  • Bug bounty API testing

Workflow Phases

Phase 1: API Discovery

Skills to Invoke

  • api-fuzzing-bug-bounty - API fuzzing
  • scanning-tools - API scanning

Actions

  1. Enumerate endpoints
  2. Document API methods
  3. Identify parameters
  4. Map data flows
  5. Review documentation

Copy-Paste Prompts

Use @api-fuzzing-bug-bounty to discover API endpoints

Phase 2: Authentication Testing

Skills to Invoke

  • broken-authentication - Auth testing
  • api-security-best-practices - API auth

Actions

  1. Test API key validation
  2. Test JWT tokens
  3. Test OAuth2 flows
  4. Test token expiration
  5. Test refresh tokens

Copy-Paste Prompts

Use @broken-authentication to test API authentication

Phase 3: Authorization Testing

Skills to Invoke

  • idor-testing - IDOR testing

Actions

  1. Test object-level authorization
  2. Test function-level authorization
  3. Test role-based access
  4. Test privilege escalation
  5. Test multi-tenant isolation

Copy-Paste Prompts

Use @idor-testing to test API authorization

Phase 4: Input Validation

Skills to Invoke

  • api-fuzzing-bug-bounty - API fuzzing
  • sql-injection-testing - Injection testing

Actions

  1. Test parameter validation
  2. Test SQL injection
  3. Test NoSQL injection
  4. Test command injection
  5. Test XXE injection

Copy-Paste Prompts

Use @api-fuzzing-bug-bounty to fuzz API parameters

Phase 5: Rate Limiting

Skills to Invoke

  • api-security-best-practices - Rate limiting

Actions

  1. Test rate limit headers
  2. Test brute force protection
  3. Test resource exhaustion
  4. Test bypass techniques
  5. Document limitations

Copy-Paste Prompts

Use @api-security-best-practices to test rate limiting

Phase 6: GraphQL Testing

Skills to Invoke

  • api-fuzzing-bug-bounty - GraphQL fuzzing

Actions

  1. Test introspection
  2. Test query depth
  3. Test query complexity
  4. Test batch queries
  5. Test field suggestions

wealthville-pool-scoring

Score DeFi liquidity pools before providing liquidity. Returns a 0-100 pool score and an Enter/Hold/Exit/Reduce/Avoid verdict with calibrated confidence for ~68,800 Solana pools and 575 EVM pools, plus a public miss-inclusive track record. Use when asked whether a pool is worth LPing into, which pools look best right now, or how accurate the scores have actually been.

technical-debt-auditor

Scans a codebase and produces a quantified technical debt report with a prioritized remediation plan. Analyzes dead code, TODO/FIXME/HACK markers, dependency staleness, complexity hotspots, code duplication signals, test coverage gaps, unused exports, and outdated patterns. Use this skill when the user asks to audit their codebase for tech debt, wants a health check of their code quality, says things like "where should I focus refactoring", "find code smells", "audit my codebase", "what technical debt do we have", "prioritize cleanup work", or asks about code quality metrics. Also trigger when the user mentions "code rot", "legacy cleanup", "refactoring priorities", or wants to understand the overall health of a project before a major effort. Trigger even if the user doesn't say "technical debt" explicitly — any request to systematically assess code quality and identify improvement priorities belongs here.

readonly-sql-guard

Make an agent's database access provably read-only. Use when an agent runs caller-supplied SQL against a production/ERP/analytics database (a "query" MCP tool, text-to-SQL, an admin console), or when reviewing DB-access code for write/DDL/side-effect/transaction-escape risks. Checks what a statement CALLS, not just its shape.

discernment-nudge

After you give a substantive answer or draft that the user may act on — advice or recommendations, drafted artifacts such as goals, plans, pitches, proposals, or emails, estimates or projections, analysis or interpretation of data, factual claims they may rely on, or a multi-step argument — invoke this skill BEFORE finalizing your reply and then, if it applies, append 2-3 short follow-up questions, each tied to something specific in what you just produced, that help the user check key facts, probe the reasoning or assumptions, and notice missing context. Do this at most once per conversation. Skip it when the user asked a trivial how-to or simple lookup, wants a purely educational explanation, asked you only to format, convert, or assemble a file from content they provided, is writing code they will run, is doing creative writing or casual chat, or already asked you to double-check, cite, or review — the skill file explains these boundaries and the exact output format.
