by mukul975conducting-api-security-testing helps authorized testers assess REST, GraphQL, and gRPC APIs for auth, authorization, rate limiting, input validation, and business-logic flaws using an OWASP API Security Top 10 workflow. Use it for structured, evidence-based API security testing and security audit reviews.
This skill scores 84/100, which means it is a solid directory listing for users who need a focused API security testing workflow. The repository gives enough operational detail to trigger the skill, understand its scope, and execute it with less guesswork than a generic prompt, though it is still better suited to authorized practitioners than casual users.
- Clear trigger and scope: it explicitly activates for API security testing, including REST, GraphQL, and API vulnerability testing.
- Strong operational leverage: the skill and reference file describe concrete tests for BOLA, BFLA, mass assignment, rate limiting, JWT bypass, and GraphQL introspection disclosure.
- Usable execution support: the repo includes a Python agent script plus a CLI example with required arguments and output behavior.
- No install command in SKILL.md, so users may need to assemble setup and invocation details themselves.
- The repository is narrowly focused on authorized penetration testing; it is not a general API debugging or load-testing skill.
Overview of conducting-api-security-testing skill
What this skill does
The conducting-api-security-testing skill helps you assess REST, GraphQL, and gRPC APIs for common security flaws using an OWASP API Security Top 10 lens. It is best for authorized penetration testers, AppSec engineers, and security auditors who need a structured way to check authentication, authorization, rate limiting, input handling, and business-logic abuse without starting from a blank prompt.
When it is the right fit
Use the conducting-api-security-testing skill when your job is to validate API exposure, not just review code or run generic scans. It is especially useful for conducting-api-security-testing for Security Audit work where you need repeatable checks across privilege levels, endpoints, and API types. If you already have a target base URL, tokens, and a rough endpoint map, this skill can turn that into a more complete test plan.
What matters most
The practical value is in its workflow: it encourages endpoint discovery, privilege comparison, and targeted checks for BOLA/IDOR, BFLA, mass assignment, rate limiting, JWT-related issues, and GraphQL-specific exposure. That makes the conducting-api-security-testing skill more decision-useful than a generic “test my API” prompt, because it pushes the model toward concrete tests and evidence collection instead of broad advice.
Important boundaries
This is a security testing workflow, not a load-testing, fuzzing, or unrestricted exploit tool. It should be used only with written authorization and safe scope boundaries. If you do not know the target’s auth model, expected roles, or whether destructive actions are allowed, the skill will be harder to use well and may produce noisy or unsafe results.
How to Use conducting-api-security-testing skill
Install and activate it
For a typical conducting-api-security-testing install, add the skill with the directory’s preferred skill manager, then open the skill files before prompting. The repo evidence points to skills/conducting-api-security-testing/SKILL.md as the activation entry, with support in references/api-reference.md and scripts/agent.py. Read those first so you know which checks are implemented and which inputs the workflow expects.
Give the skill usable test inputs
The conducting-api-security-testing usage works best when you provide:
- base URL and environment name
- auth token for a normal user
- low-privilege token or second account
- a short endpoint list or API collection
- known roles, object IDs, and any sensitive actions
A weak prompt says: “Test this API for security issues.”
A stronger prompt says: “Use conducting-api-security-testing on https://api.example.com. Focus on /v1/accounts/{id}, /v1/admin/*, and GraphQL introspection. Compare a standard user token with a read-only token, and flag any authorization bypass, mass assignment, or rate-limit weaknesses.”
Follow a practical workflow
A good conducting-api-security-testing guide sequence is:
- Confirm scope and allowed methods.
- Inventory endpoints from docs, collections, or traffic.
- Test the same action with different privilege levels.
- Probe object-level access, function-level access, and writable fields.
- Validate GraphQL-specific risks if relevant.
- Record exact request/response pairs and status-code differences.
This order matters because many API flaws only appear when the same endpoint is exercised with contrasting identities.
Read the right files first
Start with SKILL.md for activation rules and scope, then references/api-reference.md for CLI arguments and test functions, and finally scripts/agent.py to understand what the implementation actually does. That last step is important: it shows how the conducting-api-security-testing skill turns inputs into tests, which helps you avoid asking it to assess a vulnerability class the script does not meaningfully cover.
conducting-api-security-testing skill FAQ
Is this only for pen testing?
No. It is also a fit for AppSec validation, pre-release security review, and conducting-api-security-testing for Security Audit workflows where you need structured evidence about API controls. It is not a replacement for an approved penetration test plan, but it can support one.
Do I need to be a beginner to use it?
No, but beginners should bring a clearer target description than they would for a normal chat prompt. The skill is most useful when you already know the API surface, the user roles, and the allowed testing environment. Without those, the output can be too broad to act on.
How is this different from a normal prompt?
A normal prompt may produce a checklist. The conducting-api-security-testing skill is more useful because it is centered on a repeatable testing workflow, authorization-aware comparisons, and specific API weakness classes. That usually means less guesswork and better test coverage.
When should I not use it?
Do not use it for unauthorized testing, destructive traffic, or high-risk production scenarios where you cannot safely retry requests. If your goal is simple uptime monitoring or performance testing, this skill is the wrong tool.
How to Improve conducting-api-security-testing skill
Provide sharper scope and role data
The best way to improve conducting-api-security-testing usage is to give the skill concrete identities and objects: “user A can read their own order, user B is an admin, endpoint /orders/{id} returns JSON, and IDs are sequential.” That lets the model test for BOLA, BFLA, and mass assignment in a way that mirrors real abuse paths.
Include evidence the skill can compare
If you want better results, supply sample requests, a Postman collection, or captured traffic from proxy tools. Differences in headers, methods, and status codes are often what make authorization issues visible. Without that, the skill may infer tests correctly but have less to anchor them to.
Watch for common failure modes
The most common miss is asking for “all API security issues” without naming the auth model, endpoint types, or which actions are safe. Another failure mode is providing only one token, which weakens privilege-difference testing. For GraphQL, not stating whether introspection is enabled can also blur the result.
Iterate with targeted follow-ups
After the first run, refine by asking for one class of issue at a time: “Re-check object-level authorization on account and invoice endpoints,” or “Focus only on rate limiting and login abuse.” This is usually better than rerunning the full conducting-api-security-testing skill unchanged, because focused iterations produce clearer findings and more actionable remediation notes.
