🟡 MEDIUM RISK

This line still lists ReScript as the primary language, which contradicts the 'ReScript purge' described in the PR summary. If the transition is in effect, this should be updated to AffineScript to maintain consistency with the new enforcement rules.

This reference to AffineScript contradicts the primary language definition (line 22) and the TypeScript replacement entry (line 40), which both still specify ReScript. Update all references to ensure the AI agent receives consistent instructions.

🟡 MEDIUM RISK

The PR description specifies Rule 1 should be 'No new ReScript files', but the current implementation keeps it as 'No new TypeScript files'. Additionally, this rule uses the term 'AffineScript' which conflicts with the 'ReScript' designation in the main language table at line 22.

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win

Remove the retired Bun row from the banned table.

The table has two columns, but Line 45 has three cells. This triggers MD056 and leaves Bun inside the banned-tools table despite its tier-1 allowed row. Delete the retired row instead of keeping a contradictory table entry.

‼️ IMPORTANT
Carefully review the code before committing. Ensure that it accurately replaces the highlighted code, contains no missing lines, and has no issues with indentation. Thoroughly test & benchmark the code to ensure it meets the requirements.

In `@meta-a2ml/.claude/CLAUDE.md` at line 45, Remove the retired Bun row from the
banned-tools table, including its separator row, so Bun is no longer listed as
banned and the table retains its two-column structure.

⚪ LOW RISK

Nitpick: The enforcement rule references 'AffineScript', while the language table at line 23 still lists 'ReScript'. Use the following prompt to fix: Update the 'ALLOWED Languages & Tools' table in meta-a2ml/.claude/CLAUDE.md to replace 'ReScript' with 'AffineScript'.
