What it does

Bazel Test Migration is an agent skill from JetBrains/intellij-community, published by the product's own GitHub organization. Migrate IntelliJ JPS module tests to Bazel; debug Bazel-only failures.

Its SKILL.md is about 1.8k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It works with JetBrains IDEs. The repository describes itself as: IntelliJ IDEA & IntelliJ Platform.

Example prompts

  • “/bazel-test-migration”

Workflow steps

4 steps, taken from the first numbered list in SKILL.md.

  1. Identify the real test module and Bazel label.
  2. Treat .iml as the source of truth.
  3. Regenerate after every .iml or BUILD.bazel metadata change.
  4. Verify with the Bazel target the user will run.

What it can do on your machine

Read from SKILL.md and the folder at commit 562e3a2. 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:

    • git

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md. Its commands use git, which can reach the network depending on how they are called.

    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

Bazel Test Migration loads about 1.8k tokens when it runs. Until then it costs about 23 tokens; SKILL.md has 958 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~23
When it runs · the whole SKILL.md, loaded when a task matches
~1.8k

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.

SKILL.md

Its licence (Custom licence) doesn't allow us to republish the file, so here is its outline and opening line. It has 958 words (~1,827 tokens).

“Use this skill when switching an IntelliJ JPS test module to Bazel, fixing a Bazel-only test failure, or reviewing migration wiring.”
