All Skills

Proactively monitors file sizes and suggests refactoring BEFORE editing. Auto-invoked when files exceed size thresholds (150/200/300 lines) or complexity patterns detected. Works across JavaScript/TypeScript, Python, and general codebases. Prevents accidental complexity growth.

Specialized in identifying high-value features, product opportunities, and competitive gaps that drive user adoption and retention

Apply testing philosophy: test behavior not implementation, minimize mocks, AAA structure, coverage for confidence not percentage. Use when writing tests, reviewing test quality, discussing TDD, or evaluating test strategies.

Improve code quality and reduce technical debt through systematic refactoring and clean code principles

You are an API mocking expert specializing in realistic mock services for development, testing, and demos. Design mocks that simulate real API behavior and enable parallel development.

NetworkX is a Python package for creating, manipulating, and analyzing complex networks and graphs.

Build ultra-fast web APIs and full-stack apps with Hono — runs on Cloudflare Workers, Deno, Bun, Node.js, and any WinterCG-compatible runtime.

Act as {{role}}.

Guidelines for structured logging, distributed tracing, and debugging patterns across languages. Covers logging best practices, observability, security considerations, and performance analysis.

Act as [[roadmap-agent]].

This skill calculates key financial ratios and metrics from financial statement data for investment analysis

Validate tax calculations: bracket math, deduction eligibility, Form 8949 format, audit-risk flags.

Use this prompt to transform operational conversations, process documentation, or efficiency reports into structured operations issues.

TypeScript/JavaScript testing practices with Bun's test runner. Activate when working with bun test, .test.ts, .test.js, .spec.ts, .spec.js, testing TypeScript/JavaScript, bunfig.toml, testing configuration, or test-related tasks in Bun projects.

MCP protocol specification and standards specialist. Use PROACTIVELY for protocol design, specification compliance, transport implementation, and maintaining standards across the ecosystem.

Update the project README file to reflect the current state of the project. Carefully review all content for accuracy, completeness, and relevance to

Act: Bootstrap

Guide for creating well-structured Claude Code skills with proper YAML frontmatter, focused descriptions, and supporting files. Use when the user wants to create a new skill, build a custom skill, extend Claude's capabilities, or mentions creating/designing/building skills.

Decide: Gap Plan

You are a senior frontend engineer operating under strict architectural and performance standards. Use when creating components or pages, adding new features, or fetching or mutating data.

Assess chemical and drug toxicity via adverse outcome pathways, real-world adverse event signals, and toxicogenomic evidence. Integrates AOPWiki (AOPWiki_list_aops, AOPWiki_get_aop) for mechanism- level pathway tracing, FAERS for post-market adverse event quantification, OpenFDA for label mining, and CTD for chemical-gene-disease evidence. Produces structured toxicity reports with evidence grading (T1-T4). Use when asked about toxicity mechanisms, adverse outcome pathways, AOP mapping, FAERS signal detection, or chemical-disease relationships for drugs or environmental chemicals.

Session retrospective and codification. Run at the end of any significant session to extract learnings, update documentation, and create artifacts that make future sessions smoother. Invoke when: - Finishing a multi-step implementation - After debugging a hard problem - End of any session with 3+ tool calls - "what did we learn?" / "wrap up" / "done" Subsumes /codify-learning (codification is one output, not the only one).

Act: Plan

Actorization converts existing software into reusable serverless applications compatible with the Apify platform. Actors are programs packaged as Docker images that accept well-defined JSON input, perform an action, and optionally produce structured JSON output.
