name: metainformant-src-metainformant-protein-database description: METAINFORMANT rules for directory src/metainformant/protein/database. Use when editing, adding tests, or reviewing code under this path. Read the linked AGENTS.md first; use uv only, write outputs to output/, real implementations.

METAINFORMANT — src/metainformant/protein/database

Before editing files in this subtree:

• Read AGENTS.md for this folder (canonical technical context).
• Optional overview: README.md.
• Global rules: CLAUDE.md at repo root (uv, output/, .tmp/, real implementations).
• Testing policy: docs/REAL_IMPLEMENTATION_POLICY.md.
• Use metainformant.core.io for file I/O and metainformant.core.utils.logging for logs.

Keep changes scoped; match existing patterns in this directory.
