Skills real projects publish on GitHub, most starred first. Each one says what it will make an agent do before you copy it.
Files you open will collect here, so you can find them again.
Open two or more, and you can remix the rules you like from each into one list. Kept in this browser only.
TheOnlyFusionCubeSkillTheOnlyFusionCube/potetos-for-everyone/skills/architect/SKILL.md
Settle data shapes, ownership, boundaries, and interfaces before code crosses a function/module boundary. Use for non-trivial design work.

TheOnlyFusionCubeSkillTheOnlyFusionCube/potetos-for-everyone/skills/arena/SKILL.md
Spawn parallel candidate implementations for the same task, cross-judge, and graft the best parts into the winning base. Use when exploring competing designs or critical artifacts.

TheOnlyFusionCubeSkillTheOnlyFusionCube/potetos-for-everyone/skills/automate-me/SKILL.md
Create a personal mode skill from recurring workflow patterns in available history. Use when the user wants their own agent style encoded.

TheOnlyFusionCubeSkillTheOnlyFusionCube/potetos-for-everyone/skills/benchmark-checklist/SKILL.md
Vet a perf measurement (limiter, tuning, limits, errors, repeatability, relevance, and whether the work happened) before you report or act on it. Use when you run a benchmark or report a speedup or regression you measured.

TheOnlyFusionCubeSkillTheOnlyFusionCube/potetos-for-everyone/skills/blast-radius/SKILL.md
Prove what a small-looking change can affect before or after editing. Use for compatibility, caller, state, schema, or behavior impact analysis.

TheOnlyFusionCubeSkillTheOnlyFusionCube/potetos-for-everyone/skills/bro/SKILL.md
Restate the last technical explanation in plain human language with minimal jargon. Use when the user asks for a simpler version.

TheOnlyFusionCubeSkillTheOnlyFusionCube/potetos-for-everyone/skills/correct/SKILL.md
Find the mistakes agents keep repeating in this repo and make each one impossible. Try architecture first, then types, then a lint whose error names the fix, then a test, and write docs last. Prove each check fails on a real past mistake. Repeat this each time the operator corrects you. Use for /correct.

TheOnlyFusionCubeSkillTheOnlyFusionCube/potetos-for-everyone/skills/create-formal-verification-skill/SKILL.md
Generate a project-local skill that formally verifies the code where a bug costs the most and tests reach the least, in any language, with whichever verification tool fits. Use for /create-formal-verification-skill, \"model-check this race\", \"prove this invariant\", or when concurrency, retries, state machines, parsers, or unsafe code need more than tests.

TheOnlyFusionCubeSkillTheOnlyFusionCube/potetos-for-everyone/skills/create-verification-skill/SKILL.md
Generate a project-local verification skill that drives the real app and captures evidence. Use when setting up automated verification for a repo.

TheOnlyFusionCubeSkillTheOnlyFusionCube/potetos-for-everyone/skills/figure-it-out/SKILL.md
Design a rigorous custom playbook when no bundled playbook safely fits a large or unusual task. Use for cross-cutting ambiguous execution.
Often used withprinciple-explain-the-numbersetup-pstackmake-bot-ui
TheOnlyFusionCubeSkillTheOnlyFusionCube/potetos-for-everyone/skills/how/SKILL.md
Trace how a subsystem works using code and runtime evidence. Use for architecture walkthroughs, data flow, call paths, and are-we-sure investigations.
Often used withpoteto-helpsetup-pstackmake-bot-ui
TheOnlyFusionCubeSkillTheOnlyFusionCube/potetos-for-everyone/skills/interrogate/SKILL.md
Adversarially review a diff or design with independent lenses and evidence. Use before shipping contested or high-impact changes.

TheOnlyFusionCubeSkillTheOnlyFusionCube/potetos-for-everyone/skills/in-your-own-words/SKILL.md
Restate in your own words what you think the user's goals are and what problem they're trying to solve. Use for /in-your-own-words.

TheOnlyFusionCubeSkillTheOnlyFusionCube/potetos-for-everyone/skills/ketchup/SKILL.md
Catch the user up on what changed in this chat since their last message, in plain words and small visuals. List every item waiting on them with what they need to decide it from the reply alone. Use for /ketchup.

TheOnlyFusionCubeSkillTheOnlyFusionCube/potetos-for-everyone/skills/maintain-formal-verification-skill/SKILL.md
Bring a project's formal verification back in line with the code after the code changes: find the commits that touched verified code, update the model, harness, or properties to describe the code as it is now, rerun, and say whether each failure is drift in the verification or a bug in the code. Use for /maintain-formal-verification-skill, \"is the model still true to the code\", or after merges and refactors that touched verified code without rechecking it.

TheOnlyFusionCubeSkillTheOnlyFusionCube/potetos-for-everyone/skills/maintain-verification-skill/SKILL.md
Repair a project verification skill whose feature map or commands drifted. Use when app behavior and verification docs no longer agree.

TheOnlyFusionCubeSkillTheOnlyFusionCube/potetos-for-everyone/skills/make-bot-ui/SKILL.md
Build a small operator UI over an agent/webhook backend. Use when buttons or controls should trigger an agent workflow.

TheOnlyFusionCubeSkillTheOnlyFusionCube/potetos-for-everyone/skills/no-comments/SKILL.md
Remove redundant comments, dead workaround explanations, and AI tells from code while preserving necessary constraints. Use when cleaning up code or diffs.

TheOnlyFusionCubeSkillTheOnlyFusionCube/potetos-for-everyone/skills/poteto-help/SKILL.md
Guides users through pstack setup, /poteto-mode, and picking the skill, playbook, or principle for a task. Type /poteto-help with a question.

TheOnlyFusionCubeSkillTheOnlyFusionCube/potetos-for-everyone/skills/poteto-mode/SKILL.md
Lauren Tan-inspired rigorous engineering mode for concise communication, deliberate decomposition, simple code, independent review when available, and runtime verification. Use for non-trivial engineering tasks or when the user asks for Poteto Mode/pstack-style rigor.

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.
