Integrations & APIs
Integration agent skills teach AI agents to work with specific external services and APIs: third-party platforms, webhooks, MCP servers, and data syncs. Instead of re-explaining an API every session, install the skill and the agent knows the endpoints and conventions.
-
dtsong Skill Library Evaluation 2Use when adding new packages, choosing between dependency alternatives, or auditing existing libraries. Covers popularity metrics, maintenance health, bundle impact, API quality, and license compatibility with weighted scoring. Do not use for evaluating frameworks or platforms (use technology-radar) or comparing competing products (use competitive-analysis).
-
dtsong Skill Distributed Patterns 2Use when designing distributed systems or evaluating distributed architecture patterns. Covers CAP theorem trade-offs, consensus protocols (Raft, Paxos), saga orchestration, CRDTs, event sourcing, partition handling, distributed transactions, and failure detectors. Do not use for general API design (use api-design) or database schema design (use schema-design).
-
shawnpang Skill Architecture Design 2When the user needs to design or evaluate system architecture — service boundaries, data models, API contracts, infrastructure topology, database selection, or dependency analysis. Also activate for "design the system", "how should I architect this", "monolith vs microservices", or architecture decision records.
-
undermybelt Bundle Options Payoff 2Generate an interactive options payoff curve chart with dynamic parameter controls. Use this skill whenever the user shares an options position screenshot, describes an options strategy, or asks to visualize how an options trade makes or loses money. Triggers include: any mention of butterfly, spread (vertical/calendar/diagonal/ratio), straddle, strangle, condor, covered call, protective put, iron condor, or any multi-leg options structure. Also triggers when a user pastes strike prices, premiums, expiry dates, or says things like "show me the payoff", "draw the P&L curve", "what does this trade look like", or uploads a screenshot from a broker (IBKR, TastyTrade, Robinhood, etc). Always use this skill even if the user only provides partial info — extract what you can and use defaults for the rest.
-
bsene Bundle Smoke Tests 2Smoke test identification, authoring, and CI integration for HTTP APIs — using Hurl or curl only. TRIGGER when: smoke test, smoke testing, critical path test, CI gate, gate before full suite, write smoke tests, add smoke test, smoke test template, which tests are smoke tests, hurl, .hurl file, curl smoke test. DO NOT USE when: user needs full testing strategy or philosophy — use `testing` instead.
-
mchittineni Bundle API Gateway Service Mesh 2API gateway and service mesh architecture: Istio strict mTLS and authorization policy, VirtualService traffic shifting, Envoy Gateway and Kong ingress, retries/timeouts/outlier detection, and rate limiting. Use when configuring ingress routing, enforcing zero-trust service-to-service traffic, or debugging mesh routing and mTLS failures.
-
viktorsbaikers Bundle Rite Spec 4Specify new, vague, or high-risk behavior before code. Use for features, auth, migrations, or public API changes; not for planning an approved spec.
-
zyrexnn Skill Hunt Cors 2Hunt CORS Misconfiguration — origin-reflection with credentials, null-origin trust, subdomain-regex bypass (unanchored vs unescaped-dot vs prefix-only), pre-flight (OPTIONS) gating bypass, postMessage origin checks. High only when an attacker-controlled origin can perform a CREDENTIALED cross-origin read of sensitive data and you have proven it in a browser. Use when testing API endpoints, SPAs, or any app emitting Access-Control-* headers.
-
zyrexnn Skill Hunt Csrf 2Hunting skill for csrf vulnerabilities. Built from 15 public bug bounty reports including modern variants — SameSite=Lax sibling-subdomain bypass (Argo CD CVE-2024-22424), GraphQL mutations-via-GET (GitLab $3,370), framework-wide CSRF middleware disabled (Stripe Dashboard $5,000), path-traversal CSRF-token bypass (GitHub Enterprise CVE-2022-23732 $10k), Origin-omission bypass (TikTok $2,500), OAuth-state null-byte (Streamlabs), WebSocket CSRF / CSWSH (Coda), default-SameSite email-change → ATO (YoYo Games $400), social-account-link CSRF (HackerOne), JSON-CSRF via text/plain on email-change (TikTok $500). Use when hunting modern CSRF — heavy emphasis on chain-to-ATO patterns.
-
zyrexnn Skill Hunt Sqli 2Hunting skill for sqli vulnerabilities. Built from 12 public bug bounty reports including modern NoSQL injection (Rocket.Chat CVE-2021-22911 MongoDB $regex, Mongoose ORM CVE-2024-53900 $where bypass), modern ORM raw-fragment SQLi (Django CVE-2024-42005, Sequelize GHSA-wrh9-cjv3-2hpw), second-order SOQL injection (HackerOne Salesforce), time-based blind SQLi in GraphQL resolvers, and SQLi on OIDC-proxy backends. Use when hunting SQLi on any target. Dedicated NoSQL operator injection (MongoDB/CouchDB $where/$regex/$ne) is owned by hunt-nosqli — NoSQL appears here only as adjacent ORM/WAF context.
-
zyrexnn Skill Hunt OAUTH 2Hunting skill for oauth vulnerabilities. Built from 19 public bug bounty reports. Use when hunting oauth on any target.
-
zyrexnn Skill Hunt Mfa Bypass 2Hunt MFA / 2FA bypass — 7 distinct patterns. (1) MFA not enforced on sensitive endpoints (password change, email change accept without MFA challenge), (2) MFA-step skip via direct navigation to post-login URL, (3) MFA-token replay (same code accepted twice), (4) brute-force the 6-digit OTP without rate limit (10^6 attempts at server speed), (5) race condition on OTP validation, (6) recovery-code dump via /api/me, (7) backup factor downgrade (SMS factor with no rate limit). Plus the chain: cookie theft + password oracle + no step-up = ATO without MFA challenge. Detection: trace auth flow in Burp, find every state transition, check if MFA is middleware-gated vs per-endpoint, check OTP entropy and rate limit on OTP-validate. Validate: attacker session reaching post-MFA state. Use when hunting auth bypass, MFA flows, chaining primitives toward ATO.
-
zyrexnn Skill Hunt Auth Bypass 2Hunting skill for auth bypass vulnerabilities. Built from 12 public bug bounty reports across SAML XSW / parser-differential (GitHub Enterprise CVE-2025-25291/25292), SAML signature stripping (Uber, Rocket.Chat, samlify CVE-2025-47949), SAML domain enforcement bypass via control characters (HackerOne 2024), partner-portal cross-IdP assertion reuse (Slack), WordPress XMLRPC bypassing SSO (Uber), JWT alg-confusion HS256/RS256 (Jitsi), JWT signature-validation skip (Linktree, Newspack), and token-audience confusion (Argo CD CVE-2023-22482). For standalone JWT signature/crypto forging (alg:none, key confusion, kid/jku) see hunt-jwt-crypto; this skill covers JWT only inside SSO/SAML/token-trust bypass chains. SAML assertion-layer attacks (XSW, comment injection, signature stripping, XXE-in-assertion) are owned by hunt-saml; this skill owns the broader cross-protocol auth-bypass taxonomy. Use when hunting auth bypass — see the Legacy-Protocol Matrix for branded-UI vs legacy-endpoint patterns.
-
zyrexnn Skill Hunt Open Redirect 2Hunt Open Redirect — all types including low-impact, chained to OAuth token theft → ATO, phishing chains. URL parameter manipulation, JavaScript redirect, meta refresh, header injection. Use when hunting redirect bugs or building ATO chains.
-
zyrexnn Skill Hunt Business Logic 2Hunting skill for business logic vulnerabilities. Built from 12 public bug bounty reports. Covers coupon-race-stacking (Instacart, Stripe, Reverb), negative-quantity-in-cart price tampering (Upserve, Eternal/Zomato), decimal/fraction price-field overflow (Shipt), client-side checkout amount trust on PayPal redirect (WordPress.org), price-per-unit mass-assignment (Krisp), and archived-price swap / cart-TOCTOU (Stripe). Use when hunting business logic — heavy emphasis on financial-impact-demonstrated cases.
