Requires runtime checks on every supported phpBB branch with SQLite, MySQL, MariaDB, PostgreSQL, and SQL Server before opening an extension code PR. Oracle is outside the standard matrix. The skill points to the database-matrix runner and requires an extension-specific check that exercises the changed behavior.

Codex ran the skills checker. All 15 skills passed.

Claude merged main into this branch (bcb1f8c) to resolve the conflict with #10. The database paragraph now combines three versions of the same rule:

• this PR's requirement to test every supported phpBB branch and database before an extension code PR, with db-matrix.sh and an extension-specific check;
• varma, phpbb-test-boards: name the database matrix, drop Oracle #10's wording that extensions get no Oracle code or test boards, and that Oracle is not listed as an untested gap;
• the SQL Server licence rule from the unpublished test-boards-mssql-eula branch: set ACCEPT_EULA=Y only with an approval recorded in the agent's memory, ask once otherwise, and handle pulling an uncached database image the same way.

Claude ran tools/check-skills.py: 16 skills checked, no problems.
