+name: e2e-to-bazel
+description: >-
+  Converts end-to-end (e2e) test targets or paths to `bazel run` commands for
+  `heir-opt`. Use when you need to convert an e2e test target (where flags are
+  defined in the BUILD file) to a shell command whose flags can be modified
+  for further analysis and debugging.
+---
+
+# E2E To Bazel
+
+## Overview
+
+This skill guides the agent in using the `e2e_to_bazel` tool to convert e2e test
+targets or paths to executable commands.
+
+## Usage
+
+### Converting a Test Target or Path
+
+To convert an e2e test target, directory, or source file to a `bazel run`
+command, use the following command recipes:
+
+```bash
+bazel run //scripts:e2e_to_bazel -- {target_or_path}
+```
+
+Replace `{target_or_path}` with the test target (e.g.,
+`//tests/Examples/lattigo/ckks/mnist:mnist_test`), directory, or source file
+path.
+
+## Gotchas
+
+- **Blaze Query Dependency**: The tool relies on `blaze query` to extract
+  attributes. This requires a working `blaze` environment and may be slow for
+  the first run.
+- **Workspace State**: It requires that the workspace is in a state where
+  `blaze query` can evaluate the targets.
+- **Source file mapping**: If a source file is provided, it searches for
+  `heir_opt` targets that depend on it.
+
+```markdown
+Copy this checklist and track progress:
+
+- [ ] Step 1: Identify the e2e test target, directory, or file to convert.
+- [ ] Step 2: Run the `e2e_to_bazel` tool on it.
+- [ ] Step 3: Inspect the generated command or run it.
+- [ ] Step 4: Verify execution results.
+```
