stereopy-maintainerStereopy project maintenance guide for code review, bug fixing, and feature development.
Stereopy Maintainer is an agent skill from STOmics/Stereopy. Stereopy project maintenance guide for code review, bug fixing, and feature development. Use when working on stereo/ source code, fixing GitHub issues, reviewing PRs, adding tools or algorithms, modifying I/O formats, or debugging data pipeline errors.
Its SKILL.md is about 1.7k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
It sits in Development, covering Debugging and Data pipelines and ETL. It works with GitHub. The repository describes itself as: A toolkit of spatial transcriptomic analysis. The licence is MIT.
6 steps, taken from the first numbered list in SKILL.md.
Read from SKILL.md and the folder at commit 2b21b00. It shows what the files ask for, not the result of running them.
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.
Shell commands in SKILL.md call:
pythonpippytestFrom the folder's file list and the shell code blocks in SKILL.md.
No URLs in SKILL.md. Its commands use pip, which can reach the network depending on how they are called.
From URLs in SKILL.md, links to its own repository left out.
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Stereopy Maintainer loads about 1.7k tokens when it runs. Until then it costs about 68 tokens; SKILL.md has 583 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.
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); files beside SKILL.md are not scanned.
The full file from STOmics/Stereopy at commit 2b21b00, republished under its MIT licence (© STOmics). 583 words, ~1,654 tokens.

Stereopy Maintainer fits situations like: working on stereo/ source code; fixing GitHub issues; modifying I/O formats; debugging data pipeline errors.
Run `npx skills add STOmics/Stereopy --skill stereopy-maintainer -a claude-code`. Or copy the skill folder (.cursor/skills/stereopy-maintainer in STOmics/Stereopy) into .claude/skills/stereopy-maintainer in your project. Claude Code loads it when a task matches its description.
Run `npx skills add STOmics/Stereopy --skill stereopy-maintainer -a codex`. Or copy the skill folder (.cursor/skills/stereopy-maintainer in STOmics/Stereopy) into .agents/skills/stereopy-maintainer in your project. Codex loads it when a task matches its description.
Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add STOmics/Stereopy --skill stereopy-maintainer -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/stereopy-maintainer, .gemini/skills/stereopy-maintainer, .github/skills/stereopy-maintainer and .opencode/skills/stereopy-maintainer in your project.
Going by SKILL.md and its folder, Stereopy Maintainer needs the command-line tools its instructions call (python, pip and pytest). Our summary lists: Python 3.
SKILL.md contains no URLs. Its commands use pip, which can reach the network depending on how they are called. This is read from the text; nothing was executed.
Our automated static check of SKILL.md found no risky patterns, such as piping downloads into a shell, reading credential files or hidden Unicode. It is not a guarantee. Review the folder before installing.
Stereopy Maintainer is published under the MIT licence (the repository's licence). It allows redistribution, so the full SKILL.md is shown on this page.
About 1.7k tokens (SKILL.md is roughly 6.6k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full.
