Protocol for safely modifying TypeScript AST templates, enforcing compilation checks and a strict two-strike fallback rule. Trigger on requests like "edit the template", "modify packages/engine/src/plan/templates", "update the AST generator".
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# AST Template Engineer Skill ## Purpose This skill dictates how AI agents must modify TypeScript template literals (AST generators) inside the EITR engine. It guarantees that generated code templates remain syntactically valid TypeScript and prevents broken string interpolations. Trigger this skill automatically whenever you modify > 0 files matching the path `packages/engine/src/**/templates/*.ts`. ## Rules & Constraints ### 1. Mandatory Compilation Check After modifying > 0 lines in an AST template file, you MUST verify its syntax before proposing the change to the user or making a commit. - Execute exactly: `npm run typecheck` (or `npx tsc --noEmit <path-to-file>`). - If the exit code is > 0, you MUST NOT proceed. You must read the error output and attempt a fix. ### 2. The Fallback Rule (Two-Strike Limit) - If your compilation check fails >= 2 times consecutively on the same file, you MUST abort the modification. - Execute exactly: `git checkout -- <file>` to revert the file to its last committed state. - Output exactly: "ABORT: Reverting due to unresolvable AST compilation error." ### 3. Boundary Constraints & Safety …

How to install
mdr add ivanestar/eitr/ast-template-engineer@sha256:cca4c2b144e8279eThe line at the top of this page pins the label git:20260831.8563ef0, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
