Protein Key Fragment Analysis

What to check before installing or running this skill: 1) Code–doc mismatch: the docs and references repeatedly state that A/G/P (and X) are excluded from the amino-acid composition statistics, but the included script classifies A/G/P as Hydrophobic. This will materially change reported category counts, dominant-category calls, and downstream function predictions. Do not trust results until you verify/correct AA_CATEGORIES in scripts/protein_key_fragment_analysis.py and re-run a test. 2) Inspect for embedded data: the static scan found a 'base64-block' signature. Search all files for long base64-like blocks (e.g., lots of A–Z/a–z/0–9/+/=) and review their purpose. If you find any, open them and confirm they are just static example data or benign resources. 3) Run on non-sensitive data first: execute the scripts on small, public example FASTA files to confirm behavior, outputs, and runtime calls (the code calls clustalo via subprocess). Confirm no unexpected network activity (run in an isolated environment or monitor outbound connections during a test run). 4) Verify dependencies and runtime: ClustalOmega is required and invoked via subprocess. Ensure you have the correct version installed and that the environment where you run the skill is trusted. 5) Review other truncated files: the package contains many precomputed results; scan any remaining/truncated files for hidden scripts, obfuscated content, or instructions that differ from SKILL.md. Because parts of the code were truncated in the review, further review could reveal additional inconsistencies. 6) If you plan to use this for research or decision-making, validate predictions experimentally or via established annotation tools (Pfam/InterPro/AlphaFold) — the tool itself documents limitations and is heuristic. If you want, I can: (a) point to the exact lines in the script to change to make A/G/P excluded, (b) produce a small checklist of commands to run the package safely in an isolated environment, or (c) search the full file list for base64-like blocks and show their locations.
