Volcano Plot Script

Name/description (volcano plot generator) matches the included assets: SKILL.md, example data, marker list, requirements.txt, and a Python script that reads DEG CSV/TSV files and creates plots. No unrelated credentials, binaries, or network endpoints are requested.

Runtime instructions and code limit actions to reading an input data file, optional gene list, generating a plot and optionally exporting an R script. This stays within the stated purpose. Minor concerns: SKILL.md's security checklist mentions protections (e.g., preventing ../ traversal), but the provided Python code only checks existence of the input path and does not enforce workspace-restrictions or explicit path sanitization. The export_r_script function inserts args.input into the generated R script without visible escaping — if you run the tool on untrusted filenames/paths this could produce malformed or unexpected R script content. These are implementation / safety caveats rather than indicators of malicious behavior.

No install spec; it's an instruction-only skill with a requirements.txt listing typical plotting/data packages (pandas, matplotlib, seaborn, numpy). This is proportional for a local plotting tool and doesn't pull remote archives or arbitrary executables.

The skill requests no environment variables, no credentials, and no config paths. All declared dependencies are relevant to data processing and plotting.

always is false and the skill does not request persistent/privileged presence or attempt to modify other skills or system-wide settings. It performs local file I/O consistent with its purpose.
