What it does

Larp Detector is an agent skill from davidondrej/skills. Skeptical review of outside contributions to public repos. Use when reviewing, ranking, or replying to public GitHub pull requests or issues from outside contributors, or when the user says "larp-detector".

Its SKILL.md is about 470 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 Development, covering Pull requests. It works with GitHub. The repository describes itself as: access to david ondrej's personal agent skills. The licence is MIT.

When your agent uses it

  • Replying to public GitHub pull requests
  • Issues from outside contributors
  • The user says larp-detector

Example prompts

  • “larp-detector”
  • “/larp-detector”

What it can do on your machine

Read from SKILL.md and the folder at commit 7874889. 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

    No scripts in the folder and no shell commands in SKILL.md.

    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

Larp Detector loads about 465 tokens when it runs. Until then it costs about 55 tokens; SKILL.md has 290 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~55
When it runs · the whole SKILL.md, loaded when a task matches
~465

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.

Larp Detector

When reviewing this code, be careful. A lot of people on public repos just use an AI coding agent to contribute to a codebase, only for the sake of their name being on the contributors list. They also have no taste and no product feel. They're not trying to fix any real issue, any real problem, or any real bug. They literally just want to contribute.

Another common thing they do is use an AI coding agent to analyze the repo for issues, problems, and security vulnerabilities. Even if our code is good, LLMs will hallucinate hypothetical issues that would really never happen.

So be careful when reviewing this. Check that it is actually a good idea, and think about the intention of the creator. What is the intention? Did they actually face a problem and then tell their coding agent to fix it? Everybody uses AI coding agents, so that alone is not a red flag.

Really try to figure out the intention and the origin of this PR, issue, or whatever you are reviewing:

  • Did it come from an actual bug that a user encountered?
  • Did it come from genuine care for the product and a really good idea for how to improve it?
  • Or is it just a fake improvement, or support for something we don't need?
  • Or does it try to fix issues that were artificially found by an LLM, but would never happen given the existing usage patterns of existing users?

Be careful. A lot of the code you're going to review is complete nonsense. It's created by people who have no product taste, are not technical, and just tell an AI coding agent to contribute something for the sake of contributing something.
