Prompt Template Linter

Lint a prompt template for the issues that cause injection and flaky output. It detects problems; it does not write prompts.

What it flags

Untrusted variables interpolated straight into the instructions, the injection surface.
Placeholders never provided, or provided variables never used.
Contradictory instructions.
A missing output-format spec where the result is parsed.
Unbounded context interpolation and leftover placeholders.

How to run

Point it at your prompt files or pipe one in. Read-only.

Good to know

This is a heuristic linter. The injection check flags surface, not a confirmed exploit.

Is Prompt Template Linter the right skill?

Best fit

Lints prompt templates for injection surface, missing or unused variables, contradictory instructions, a missing output-format spec where the result is parsed, unbounded context interpolation, and leftover placeholders. A detector, not a generator.

Do not use it as

Do not treat a successful run as proof beyond the supplied files, declared scope, and evidence the skill actually checked.

No. It is the opposite, a lint-and-safety pass on a template you already have.

Does it confirm an exploit?
