What it does

Test Run is an agent skill from mrchantey/beet. Run the core test suite (just test-core) to a clean, warning-free pass, with recipes for hanging tests and mold linker flakes. Use when asked to run or fix the test suite.

Its SKILL.md is about 540 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 Test generation. The repository describes itself as: A malleable engine built on interoperable standards. The licence is Apache-2.0.

When your agent uses it

  • Fix the test suite
  • Tasks that involve Test generation

Example prompts

  • “/test-run”

What it can do on your machine

Read from SKILL.md and the folder at commit 38648b8. 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:

    • just
    • cargo

    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

Test Run loads about 544 tokens when it runs. Until then it costs about 45 tokens; SKILL.md has 303 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~45
When it runs · the whole SKILL.md, loaded when a task matches
~544

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.

Run the core test suite (just test-core) to a clean, warning-free pass, with recipes for hanging tests and mold linker flakes. Use when asked to run or fix the test suite.

Run Tests

Context

Always use tail when running tests to preserve context. Run all tests piping the entire output to .agents/tmp/scratch.txt, use this for all commands, so that multiple greps can be applied without rerunning the tests.

Hanging Tests

If instructed, or you suspect, that some tests may hang, use timeout to catch these. Run an exponential backoff timeout, starting with two minutes, to catch hanging tests once you find a hanging test, shorten the timeout as much as possible to speed iteration cycles. When debugging hanging tests always pass the log-runs flag to detect the tests that dont finish, ie: timeout 120 cargo test -p beet_core --lib -- --log-runs. This will help you determine which test didnt complete

Compile Errors

these sweeping tests perform large compilations and sometimes the mold linker trips up. try running again, and if it still trips up sometimes incrementing the workspace and crates version, ie find-replace Cargo.toml 0.0.9-dev.6, ..dev.7, will unstuck it. A classic linker error is: help: you can increase rustc's stack size by setting RUST_MIN_STACK=.. this can usually be fixed by running again, and getting a little further down the compilation step.

Instructions

Run just test-core If you encounter an error, isolate it and run again, ie if the error is in beet_core lib: cargo test -p beet_core --all-features --lib -- test_name Fix the error using a subagent, then run the crate again: cargo test -p beet_core --all-features When thats clear, run the full suite again just test-core | tail After the first complete pass, run fully again, checking for warnings. Fix any warnings encountered

Success

Success means that just test-core passes without warnings. Every warning counts, including ones in code you did not touch or another agent just committed: fix it, do not report it as pre-existing. Upon completion provide a comprehensive summary of what was changed.
