malekokour Bundle Review Fih Dose RationaleReviews an already-written first-in-human starting-dose rationale — the most-sensitive-species argument, the NOAEL to HED to MRSD conversion chain, the MABEL consideration where the mechanism indicates one, and the escalation and stopping-rule skeleton — and recomputes every arithmetic step with a printed audit trail. Use this skill when someone asks to check, QC, verify or review an existing FIH dose rationale, IB dose-justification section or protocol starting-dose narrative — for example "does the HED in this IB recompute from the rat NOAEL" or "review the dose rationale before it goes to tox and the medical monitor". Do not use it to derive, select, propose, justify or approve a starting dose, to set or adjust an escalation increment, to judge whether a safety factor or staggering interval is adequate, or to prepare a registration-dose justification.

uphiago Skill Hunt AtoHunt 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 (alg:none, RS256→HS256 key confusion, weak HMAC secret, kid injection), (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.

uphiago Skill Hunt API MisconfigHunt API security misconfiguration — mass assignment, JWT attacks, prototype pollution, HTTP verb tampering. Mass assignment: send {is_admin:true, role:admin, verified:true} on profile/account/reset endpoints — server blindly applies. JWT: alg=none, weak HMAC bruteforce, kid path traversal, JWK injection, token confusion. 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, JWT flaws, mass-assignment, prototype pollution.

gianlucanaarden Skill Ankertekst AnalistAnalyseert de ankerteksten van een lijst backlinks, deelt elke linktekst in bij een van vier typen (merknaam, omschrijvend, kale URL, exact zoekwoord) en wijst eenzijdigheid aan, zonder een verzonnen normverdeling te hanteren. Werkt op een export uit Google Search Console of een handmatig aangeleverde lijst, benoemt per twijfelgeval waarom een tekst bij een type hoort, zoekt bij een dominante stapel naar de gezamenlijke bron en adviseert hoe je vanaf nu varieert zonder overcorrectie. Gebruik deze skill wanneer iemand vraagt om "analyseer mijn ankerteksten", "anchor text audit", "is mijn linkprofiel natuurlijk", "te veel exact match ankers", "ankertekst verdeling checken", "linkteksten uit Search Console beoordelen", "welke ankertekst moet ik gebruiken", of een lijst backlinks met linkteksten aanlevert. Ook triggeren bij het kiezen van een ankertekst voor een nieuw gastartikel of een linkruil. Niet gebruiken om een ideale percentageverdeling voor te schrijven, want Google publiceert geen ankertekst-ratio's en
