io.github.apache/doris/code-review

Review code with Doris-specific checklists

io.github.jleechanorg/claude-commands/automation-output-verification

Use BEFORE running any automation loop. Requires stating the observable success output (PR, fixed test, push); rejects prediction-only loops.

io.github.jleechanorg/claude-commands/automation-completeness

Use when adding automation scripts. Requires a caller (CI/cron/hook); watchdog scripts need launchd plist template + deploy.sh install step.

io.github.TheGoat395/Codex-Skills/css-grid-editorial-systems

Create CSS Grid editorial layout systems for premium websites. Use for asymmetric grids, magazine layouts, portfolio indexes, case-study plates, image galleries, hero compositions, feature narratives, product proof layouts, masonry-like rhythms, and replacing generic card grids with stronger hierarchy.

io.github.addyosmani/agent-skills/code-review-and-quality

Conducts multi-axis code review. Use before merging any change. Use when reviewing code written by yourself, another agent, or a human. Use when you need to assess code quality across multiple dimensions before it enters the main branch.

io.github.mohitagw15856/pm-claude-skills/sql-query-explainer

Explains, optimises, writes, and documents SQL queries. Use when asked to explain a SQL query, optimise slow SQL, translate SQL to plain English for non-technical stakeholders, write a query from a natural language description, or produce query documentation. Produces plain-English explanations, annotated optimised queries, or a data dictionary covering output shape, assumptions, and known limitations. Works across PostgreSQL, MySQL, BigQuery, Snowflake, and standard SQL.

io.github.ktolonen/ultiorganizer/css-style-and-lint

Analyze, lint, and safely fix Ultiorganizer CSS changes. Use when Codex edits or reviews CSS files under cust/, mobile app styling, skin overrides, or shared stylesheet rules; when checking style/color consistency; or when deciding whether duplicated selectors and utility classes should be consolidated. Run Stylelint on changed CSS and apply only low-risk fixes unless the user asks for broader visual refactoring.

io.github.proma-ai/Proma/writing-plans

Use when you have a spec or requirements for a multi-step task, before touching code

io.github.mohitagw15856/pm-claude-skills/writing-great-skills

Author a high-quality Agent Skill (SKILL.md) that an AI reliably triggers and executes well — strong frontmatter, a sharp description with trigger phrases, a clear output contract, quality checks, and anti-patterns. Use when asked to write a skill, create a SKILL.md, improve a skill, review a skill for quality, or contribute to a skills library. Produces a complete, SkillCheck-passing SKILL.md plus a short rationale for the key choices.

io.github.kortix-ai/suna/testing

The mandatory test-with-every-change discipline for this monorepo. Load WHENEVER you write, change, refactor, or remove ANY code under apps/** or packages/** — a function, class, route, component, hook, schema, migration, config, or bug fix — and whenever you touch anything under tests/, add coverage, run a suite, set up CI, or are asked why a gate failed. Defines which test type each change needs (unit/integration/contract/api/e2e/a11y/visual/perf/security), the exact commands and conventions (co-located bun:test, factories, determinism, no comments), and the CI gates that enforce it. Enforces THE RULE: every possible change ships with tests in the same change.

io.github.shareAI-lab/Kode-CLI/frontend-design

Create distinctive, production-grade frontend interfaces with high design quality. Use this skill when the user asks to build web components, pages, artifacts, posters, or applications (examples include websites, landing pages, dashboards, React components, HTML/CSS layouts, or when styling/beautifying any web UI). Generates creative, polished code and UI design that avoids generic AI aesthetics.

io.github.shareAI-lab/Kode-CLI/mcp-builder

Guide for building high-quality MCP (Model Context Protocol) servers and tools: what MCP is, how to design tools/resources/prompts for agent usability, and how to implement servers in TypeScript or Python. Use when you need MCP best practices, server architecture patterns, or a step-by-step build workflow (with language preference).

io.github.jxxghp/MoviePilot/database-operation

Use this skill when you need to inspect, query, maintain, or carefully modify the MoviePilot database. This skill uses the bundled scripts/mp-db.py helper, which reads MoviePilot local settings itself and never requires database passwords or full PostgreSQL DSNs in the agent prompt. Applicable scenarios include data statistics, counts, aggregations, inspecting or fixing records, cleanup requests, and questions like "how many downloads", "show site stats", "delete old records", or "why is this subscription stuck".

io.github.agentscope-ai/AgentTeams/mcporter

Discover and call MCP Server tools via the mcporter CLI. Use when your coordinator notifies you about new MCP tools, or when you need to call external APIs. Includes workflow for generating skill documentation for new MCP servers.

io.github.shinpr/claude-code-workflows/typescript-rules
