Leetcode Py

What it does

When your agent uses it

• A repository needs coding interview practice scaffolding: generating problem directories (README
• Parametrized pytest suite
• Setting up collections like Blind 75
• Testing LeetCode solutions with loguru-logged

Example prompts

• “set up interview prep repo”
• “add leetcode problem”
• “practice grind 75 in python”
• “/leetcode-py”

Requirements

• Python 3
• Node.js
• Compatibility (from SKILL.md): Requires Python 3.10+. The lcpy CLI runs in any repo; bake tasks need this repo cloned.

What it can do on your machine

Read from SKILL.md and the folder at commit 9155db3. It shows what the files ask for, not the result of running them.

• Tool permissions

  Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

  From allowed-tools in the SKILL.md frontmatter.

• Runs code

  Shell commands in SKILL.md call:

  • pip
  • uv
  • npx

  From the folder's file list and the shell code blocks in SKILL.md.

• Network

  Hosts in commands or code, which the agent is likely to contact:

  • leetcode-py.wisl.dev

  From URLs in SKILL.md, links to its own repository left out.

• Credentials

  Names no API keys, tokens, secrets or passwords.

  From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

• Compatibility

  Requires Python 3.10+. The lcpy CLI runs in any repo; bake tasks need this repo cloned.

  From compatibility in the SKILL.md frontmatter.

Context cost

Leetcode Py loads about 1.4k tokens when it runs. Until then it costs about 202 tokens; SKILL.md has 397 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it

~202

When it runs · the whole SKILL.md, loaded when a task matches

~1.4k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

description

Generates Python LeetCode practice environments and manages a 307-problem catalog with the lcpy CLI. Use when a repository needs coding interview practice scaffolding: generating problem directories (README, solution stub, parametrized pytest suite, helpers, notebook); setting up collections like Blind 75, Grind 75, Grind 169, NeetCode 150, NeetCode 250, or Algo Master 75; testing LeetCode solutions with loguru-logged, parametrized suites; visualizing TreeNode, ListNode, or GraphNode structures; or scraping LeetCode problem data as JSON. Use even if leetcode-py is not named: "set up interview prep repo", "add leetcode problem", "practice grind 75 in python". Do NOT use for submitting to leetcode.com, fetching judge results or contest rankings, or non-LeetCode competitive programming.

compatibility

Requires Python 3.10+. The lcpy CLI runs in any repo; bake tasks need this repo cloned.
