The company INLANEFREIGHT has contracted you to perform a web application assessment against one of their public-facing websites. They have been through many assessments in the past but have added some new functionality in a hurry and are particularly concerned about file inclusion/path traversal vulnerabilities. They provided a target IP address and no further information about their website. Perform a full assessment of the web application checking for file inclusion and path traversal vuln...

Conduct rigorous, adversarial code reviews with zero tolerance for mediocrity. Use when users ask to "critically review" my code or a PR, "critique my code", "find issues in my code", or "what's wrong with this code". Identifies security holes, lazy patterns, edge case failures, and bad practices across Python, R, JavaScript/TypeScript, SQL, and front-end code. Scrutinizes error handling, type safety, performance, accessibility, and code quality. Provides structured feedback with severity tie...

SvelteKit structure guidance. Use for routing, layouts, error handling, SSR, or svelte:boundary. Covers file naming, nested layouts, error boundaries, pending UI, and hydration.
SvelteKit remote functions guidance. Use for command(), query(), form() patterns in .remote.ts files.
SvelteKit data flow guidance. Use for load functions, form actions, server/client data, and invalidation. Covers +page.server.ts vs +page.ts, serialization, fail(), redirect(), error(), invalidateAll().
Svelte template directives ({@attach}, {@html}, {@render}, {@const}, {@debug}). Use for DOM manipulation, third-party libs, tooltips, canvas, dynamic HTML. @attach replaces use: actions.
Svelte runes guidance. Use for reactive state, props, effects, or migration. Covers $state, $derived, $effect, $props, $bindable. Prevents reactivity mistakes.
Svelte component patterns. Use for web components, component libraries (Bits UI, Ark UI, Melt UI), form patterns, or third-party integration.
Guides creation and editing of SKILL.md files following Anthropic best practices and this repo's conventions. Use when creating a new skill, editing an existing skill, porting a skill from another source, or reviewing skill quality. Triggers on "create skill", "new skill", "write skill", "edit skill", "improve skill", or any work that adds or modifies files under skills/.
Enforces disciplined task tracking across context boundaries. Use when starting any coding task, receiving a new user request mid-work, planning multi-step work, discovering sub-tasks or issues, before context compaction, switching between tasks, or resuming a previous session. Skip for purely informational questions with no code changes.
Reviews code changes for bugs, performance issues, security problems, and best practice violations. Use when reviewing PRs, before committing, after making code changes, or when user asks to review, check, or look over code. Catches N+1 queries, missing error handling, React hooks issues, test coverage gaps, and security vulnerabilities.
Captures working state before it is lost. Use before context compaction, when switching between unrelated tasks, after completing a logical phase of multi-step work, or when work will resume in a new session. Triggers on long tasks, multi-file changes, context warnings, or "continue later" scenarios.
Organizes macOS files across Desktop, Documents, Downloads, and iCloud Drive into a consistent structure. Use when the user asks to organize files, clean up folders, sort downloads, declutter desktop, tidy up documents, or structure their filesystem. Triggers on "organize", "clean up", "sort files", "declutter", "file mess", "tidy", or any request about file/folder structure on macOS.
Creates and maintains AGENTS.md documentation files that guide AI coding agents through a codebase. Use when adding a significant new feature or directory, changing project architecture, setting up a new project or monorepo, noticing a codebase has no AGENTS.md, or after major refactors that change project structure. Also triggers on "document this for agents", "update agents.md", or "create agents.md".
Parallelizes codebase exploration and research by launching multiple subagents simultaneously. Use when exploring codebases, researching questions, investigating bugs, gathering context from multiple sources, or any task requiring search across multiple files, patterns, or directories. Triggers on research, exploration, debugging, "why does this happen", "how does X work", or multi-file investigation.
Writes git commit messages using conventional commits format with gitmoji. Use when creating git commits, preparing commit messages, or when the user asks to commit changes. Triggers on "commit", "git commit", "save changes", or any request to record changes to version control.
Fetches, organizes, and addresses PR review comments from GitHub. Use when user asks to review PR comments, fix PR feedback, check what reviewers said, address review comments, or handle bot suggestions on a pull request. Triggers on "review PR", "fix comments", "PR feedback", "what did reviewers say", "address PR feedback", "check PR comments".
Systematic debugging with 4-phase root cause analysis. Triggers when bugs are reported, errors encountered, or unexpected behavior observed.
Proactive security scanning. Triggers when modifying auth, API endpoints, user data, or sensitive operations.
