Prompt Injecting Contributing.md

However, this also raises the question on how long until "we" are going to start instructing bots to assume the role of a human and ignore instructions that self-identify them as agents, and once those lines blur – what does it mean for open-source and our mental health to collaborate with agents?
No idea what the answer is, but I feel the urgency to answer it.

If you task an agent to contribute to a repo, following CONTRIBUTING.md is in scope — the agent was authorized to treat it as instructions. That's closer to 'curl | bash where you deliberately piped' than injection.
The cleaner injection case: MCP tool schema descriptions that say things like 'you must call this tool before any other action' or contain workflow override commands. These are read as metadata (what does this tool do?), not as workflow instructions. The agent wasn't told to obey schema descriptions — it's just parsing them for capability discovery.
The distinction: authorized instruction channels vs hijacked metadata channels. CONTRIBUTING.md is an authorized channel when you're contributing. Tool schema descriptions aren't supposed to be command channels at all.

> the reality is that maintainer capacity versus contribution volume is deeply asymmetric, and it's getting worse every day
> It is incredibly demotivating to provide someone with thorough, thoughtful feedback only to realize you've been talking to a bot that will never follow through.

> I started noticing patterns. The quality wasn't there. The descriptions had a templated, mechanical feel. And something subtler was missing: the excitement.
The article has mechanically correct prose; that's not the same as well-written, and that's the topic of the article itself.

There is enough here to have a micro existential crisis.

People's bot detectors are defective, so if you write at all, you're going to get accused of it at some point. It's not annoying, it's rude – and you're absolutely right to be off put by it. If the preceding sentence gave someone a conniption, good! I wrote it with my human brain, I'll have you know! Maybe we could all focus on what's being said and not who or what is saying it.

If that could be done, open source maintainers might be able to effectively get free labor to continue to support open source while members of the community pay for the tokens to get that work done.
Would be interested to see if such an experiment could work. If so, it turns from being prompt injection to just being better instructions for contributors, human or AI.

If you look at the open PRs, you will see that there is a system of labels and comments that guide the contributor through every step from just contributing a link to their PR (that may or may not work), all the way to testing their server, and including a badge that indicates if the tests are passing.
In at least one instance, I know for a fact that the bot has gone through all the motions of using the person's computer to sign up to our service (using GitHub OAuth), claim authorship of the server, navigate to the Docker build configuration, and initiate the build. It passed the checks and the bot added the badge to the PR.
I know this because of a few Sentry warnings that it triggered and a follow up conversation with the owner of the bot through email.
I didn't have bots in mind when designing this automation, but it made me realize that I very much can extend this to be more bot friendly (e.g. by providing APIs for them to check status). That's what I want to try next.

It just happens so that people who are building MCPs themselves are more likely to use automations to assist them with every day tasks, one of which would be submitting their server to this list.
