What it does
Compare Python Typecheckers is an agent skill from JetBrains/intellij-community, published by the product's own GitHub organization. Compare Python type inference with ty, pyrefly, and basedpyright.
Its SKILL.md is about 620 tokens, which your agent loads only when the skill is triggered. The skill folder holds 2 other files, including scripts (for example `scripts/compare_typecheckers.py`).
It works with Python and JetBrains IDEs. The repository describes itself as: IntelliJ IDEA & IntelliJ Platform.
Example prompts
- “/compare-python-typecheckers”
Requirements
- Python 3
What it can do on your machine
Read from SKILL.md and the folder at commit 562e3a2. 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
Ships 1 file in scripts/ (Python), which the agent can run.
Shell commands in SKILL.md call:
uvxuv
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md. Its commands use uvx and uv, which can reach the network depending on how they are called.
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.
Context cost
Compare Python Typecheckers loads about 617 tokens when it runs. Until then it costs about 23 tokens; SKILL.md has 283 words of instructions outside code blocks.
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
Auto-check passed
The automated check found no risky patterns in SKILL.md.
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); the scripts in this folder are not scanned.
SKILL.md
Its licence (Custom licence) doesn't allow us to republish the file, so here is its outline and opening line. It has 283 words (~617 tokens).
“When reasoning about how PyCharm should infer a type or whether something ought to be a type error, cross-checking against the real third-party checkers is the fastest way to gain insight — and to see where they disagree. This skill…”
