AI Agent Skill: Master TypeScript AST Template Modifications

AI Agent Skill: Master TypeScript AST Template Modifications

The AI Agent Skill enables controlled and precise modifications of TypeScript Abstract Syntax Tree (AST) templates within the EITR engine. It ensures that changes remain syntactically valid TypeScript and guarantees successful code generation by enforcing strict compilation checks and a two-strike fallback rule for modifications.

What this skill does

• Triggers automatically whenever modifications are detected in files matching the path packages/engine/src/**/templates/*.ts.
• Conducts mandatory syntax verification by executing npm run typecheck or npx tsc --noEmit after any change, halting further action if syntax errors are detected.
• Implements a two-strike rule where, after two consecutive syntax check failures on the same file, modifications are aborted and reverted to the last committed state using git checkout --. Outputs a specific message upon reversion: "ABORT: Reverting due to unresolvable AST compilation error."
• Restricts the use of the multi_replace_file_content tool for template refactors if string modifications exceed 50 lines.

Who it is for

This skill is ideal for developers and teams utilizing AI coding agents such as Claude Code, Cursor, and Codex. It supports users engaged in developing and maintaining complex TypeScript projects requiring impeccable template management.

Use cases

• Seamlessly update TypeScript AST templates during large-scale project refactoring, ensuring each change is syntactically verified before consolidation.
• Enhance collaborative development workflows by automating template syntax checks, reducing potential for human error during manual template modifications.
• Develop and maintain TypeScript-heavy applications with reliability, thanks to enforced fallback mechanisms that maintain project integrity.

Technical details

• Compatibility with AI coding agents: Claude Code, Cursor, Codex.
• Incorporates tools such as npm and npx for syntax verification.
• Utilizes git for version control, specifically employing git checkout for safe rollbacks.
