Update .vscode/launch.json to debug a specific CTest test by name.

  • AI & LLM Engineering work in your project
  • Calls python3

What it does

Debug Test is an agent skill from celeritas-project/celeritas. Update .vscode/launch.json to debug a specific CTest test by name.

Its SKILL.md is about 200 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 AI & LLM Engineering. It works with Visual Studio Code and CUDA. The repository describes itself as: Celeritas is a new Monte Carlo transport code designed to accelerate scientific discovery in high energy physics by improving detector simulation throughput and energy efficiency…

When your agent uses it

  • AI & LLM Engineering work in your project

Example prompts

  • “/debug-test”

Requirements

  • Python 3

What it can do on your machine

Read from SKILL.md and the folder at commit b5bd5b5. 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:

    • python3

    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

Debug Test loads about 199 tokens when it runs. Until then it costs about 19 tokens; SKILL.md has 76 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~19
When it runs · the whole SKILL.md, loaded when a task matches
~199

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 76 words (~199 tokens).

“Update .vscode/launch.json so its first debug configuration runs the CTest test whose name (or substring) is $ARGUMENTS. If no name was given, ask for one.”
