-
bsene Skill REST API Design 2REST API design best practices — URI naming, HTTP verbs/status codes, pagination, filtering, error envelopes, versioning, security. Based on Octo's API design guide with modern updates. TRIGGER when: designing REST API, designing endpoint, API design review, URL design, resource naming, HTTP verb choice, status code choice, pagination strategy, cursor vs page pagination, error format, response envelope, API versioning, REST conventions, RESTful, "/users vs /user", PATCH vs PUT, 201 vs 200, 400 vs 422, idempotency key, rate limiting headers, expand/include parameter, HATEOAS, OAuth2, reviewing routes/controllers/handlers. DO NOT USE when: GraphQL, gRPC, WebSocket, or RPC-style APIs; pure backend logic unrelated to HTTP surface; OpenAPI/Swagger tooling questions only (use generic tools).
-
bsene Bundle Writing A Good Agents Md 2Write, audit, or improve AGENTS.md — the tool-agnostic context file for coding agents — plus harness adapters (CLAUDE.md, .cursorrules, GEMINI.md, Copilot instructions). Use when creating one from scratch, auditing for bloat or anti-patterns, consolidating multiple tool files into one source of truth, or applying progressive disclosure.
-

-
viktorsbaikers Bundle Rite Frame 3Frame an ad-hoc ask before coding, then audit the diff. Use for underspecified imperative asks, raw-diff self-audits, or `/rite-quick` setup. Not a lifecycle gate.

-
zyrexnn Skill Hunt Ato 2Hunt account takeover taxonomy — 9 distinct paths to ATO, plus chains. Paths: (1) password reset flaws (host-header injection redirects token, predictable/numeric token, Referer leak, no-expiry/reuse), (2) email change without re-auth, (3) OAuth account-link CSRF, (4) MFA bypass (per hunt-mfa-bypass), (5) session fixation, (6) JWT manipulation (forge token to another identity; crypto details → hunt-jwt-crypto), (7) password change without step-up (chain with login timing/length oracle), (8) social-recovery / security-question brute-force, (9) SSO subdomain takeover at OAuth redirect_uri. Chains: cookie theft + password oracle + no step-up = persistent ATO; lax redirect_uri = auth-code theft; dangling-CNAME takeover at redirect_uri = ATO. Validate: demonstrate real takeover of test account B from attacker A's session; OOB/Collaborator confirm blind token-leak steps. Use when hunting ATO chains, testing password reset / email change / MFA / OAuth / session / JWT, or chaining primitives toward Critical.
-
zyrexnn Skill Hunt JWT Crypto 2Hunt JWT cryptographic failures — alg:none signature-stripping and RS256→HS256 key-confusion that let an attacker forge a token for any identity (e.g. an admin) without knowing a secret. Use when the app authenticates with a JSON Web Token (an `eyJ...` Bearer token in the Authorization header, a cookie, or a login response). This skill OWNS JWT signature/crypto forgery (alg:none, key confusion, kid/jku header injection); hunt-ato covers JWT as one ATO path, hunt-auth-bypass covers SSO/SAML token trust, hunt-api-misconfig covers non-crypto JWT handling. Critical when a forged token grants access to another user's data or an admin-only endpoint.
-
zyrexnn Skill Meme Coin Audit 2Meme coin and token security audit — rug pull detection (honeypot, hidden mint, fee manipulation, LP lock bypass), Solana SPL token analysis (freeze authority, mint authority, metadata mutability), Token-2022 extension risks (transfer hooks, permanent delegate), DEX liquidity pool attacks (sandwich amplification, LP drain, bonding curve exploits), pump.fun/Raydium/Jupiter integration risks, and real exploit examples from 2024-2025. Use for any token audit, rug pull assessment, meme coin security review, or pre-investment due diligence.
-
zyrexnn Skill Security Arsenal 2Security payloads, bypass tables, wordlists, gf pattern names, always-rejected bug list, and conditionally-valid-with-chain table. Use when you need specific payloads for XSS/SSRF/SQLi/XXE/NoSQLi/command injection/SSTI/IDOR/path-traversal/HTTP smuggling/WebSocket/MFA bypass, or bypass techniques. Submittability and the always-rejected / what-NOT-to-submit decision are owned by triage-validation.
-
zyrexnn Skill Hunt API Misconfig 2Hunt API security misconfiguration — mass assignment, prototype pollution, HTTP verb tampering. Mass assignment: send {is_admin:true, role:admin, verified:true} on profile/account/reset endpoints — server blindly applies. JWT signature/crypto forging (alg:none, key confusion, kid/jku) is owned by hunt-jwt-crypto; this skill covers only non-crypto JWT handling. Prototype pollution: __proto__ injection in JSON merge / Object.assign / lodash _.merge → polluted prototype reaches sink (RCE in Node, XSS in browser). HTTP verb: GET-bypass-CSRF, X-HTTP-Method-Override, TRACE enabled. Detection: API responses with extra fields, JWTs in headers (decode at jwt.io). CORS misconfiguration (reflect-any-origin, null origin, subdomain-regex bypass, postMessage) is owned by hunt-cors. Use when hunting API misconfigs, mass-assignment, prototype pollution (JWT crypto → hunt-jwt-crypto).
-
zyrexnn Skill Hunt Race Condition 2Hunting skill for race condition vulnerabilities. Built from 12 public bug bounty reports including modern HTTP/2 single-packet attack cases (James Kettle DEF CON 2023 "Smashing the State Machine"; RyotaK / Flatt Security 10,000-request first-sequence-sync expansion 2024). Covers coupon double-redemption, gift-card double-spend, MFA-OTP-validate race, account-create race, faucet/crypto token double-mint, email-activation race, vote/upvote inflation, password-reset token race, rate-limit bypass via concurrent requests. Use when hunting race conditions, TOCTOU bugs, MFA-bypass-via-timing.
-
arasz Skill Review Changes 2Use when reviewing a diff, PR, or a batch of changed files and you need to know where the risk concentrates — which changed units have the largest blast radius, whether the highest-risk ones are actually covered by tests, and whether the result is safe to merge. Trigger phrases: "review these changes", "how risky is this diff", "what's the blast radius", "did anything untested change", "rank these changes by risk". Not for a pass/fail preflight of style, security, and layering checks — that is `code-review-checklist`; run the checklist for the mechanical gates and reach for this skill to decide where its attention should concentrate. The two compose: checklist for gates, this skill for prioritization.
-
arasz Bundle Call Behaviorist 3Use when ai-badger's own machinery needs to be observed — "did that hook even run?", "enable debug logging", "why is the drift notice silent?", "turn on the audit log", "what did the hooks do?" — or to check, tail, or switch off that logging. Records which hook ran, in which project, under which version, to an append-only log.
