What it does
E2E To Bazel is an agent skill from google/heir, published by the product's own GitHub organization. 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.
Its SKILL.md is about 390 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
It sits in Testing & QA, covering End-to-end testing. The repository describes itself as: The compiler for homomorphic encryption. The licence is Apache-2.0.
When your agent uses it
- Tasks that involve End-to-end testing
Example prompts
- “Use the e2e-to-bazel skill to convert end-to-end (e2e) test targets or paths to bazel run commands for heir-opt”
- “/e2e-to-bazel”
What it can do on your machine
Read from SKILL.md and the folder at commit 4721d8d. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
Shell commands in SKILL.md call:
bazel
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
E2E To Bazel loads about 394 tokens when it runs. Until then it costs about 69 tokens; SKILL.md has 127 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

- 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:
bazel run //third_party/heir/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
bazel queryto extract attributes. This requires a workingblazeenvironment and may be slow for the first run. - Workspace State: It requires that the workspace is in a state where
bazel querycan evaluate the targets. - Source file mapping: If a source file is provided, it searches for
heir_opttargets that depend on it.
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.<!-- mdformat global-off -->© google, Apache-2.0. Rendered from Markdown: HTML in the file is shown as text, images as links, and headings moved down two levels. Raw file
