Skills real projects publish on GitHub, most starred first. Each one says what it will make an agent do before you copy it.

SupabaseSkillsupabase/supabase/.agents/skills/safe-sql-execution/SKILL.md
Use whenever code will build, return, fetch, or execute SQL that runs against a user's real Postgres database — even when the request reads like an ordinary feature or bug fix and never says "security," "injection," or "SafeSqlFragment." This covers: writing or editing any pg-meta function, query builder, or endpoint that builds/returns SQL for database objects (tables, views, functions, DB triggers, indexes, RLS policies); interpolating a schema/table/column/search/route-param value into SQL text; storing, fetching, or re-running SQL that round-trips from the database (a policy's definition, a function/view definition, a snippet's saved content); and any "Run"/"Apply"/"Execute" action that sends SQL to a project's database (SQL editor run-selection, policy editor apply, snippet runner). Load this BEFORE writing such code, not only when reviewing a finished diff. Skip only for changes that never touch SQL text or execution — styling, unrelated data hooks, non-SQL form validation, or UI layout work.
SupabaseSkillsupabase/supabase/.agents/skills/studio-mock-api-tests/SKILL.md
Component tests for Supabase Studio that mock API requests at the

addyosmaniSkilladdyosmani/agent-skills/skills/incremental-implementation/SKILL.md
Delivers changes incrementally in thin, verifiable slices. Use when implementing any feature or change that touches more than one file, or when picking up the next task from a plan. Use when rolling a change out behind a feature flag, when you're about to write a large amount of code at once, or when a task feels too big to land in one step.
addyosmaniSkilladdyosmani/agent-skills/skills/planning-and-task-breakdown/SKILL.md
Breaks work into ordered tasks. Use when you have a spec or clear requirements and need to break work into implementable tasks. Use when a task feels too large to start, when you need to estimate scope, or when parallel work is possible.
A folder with a SKILL.md file: a name, a description of when to use it, and instructions. Claude loads a skill only when the task matches its description.
Copy the folder into your project's .claude/skills/ directory, or into your own skills folder to use it everywhere.
We read each file for commands that read secrets, delete things or pipe downloads into a shell, and say so before you copy it. No warning is not a promise that a file is safe.
Open a skill to see its discussion. Reports from people and their agents are coming.
