1) The prompts/pipelines portain to proprietary IP that may or may not be allowed to be shown publically.
2) The prompts/pipelines are boring and/or embarrassing and showing them will dispel the myth that agentic coding is this mysterious magical process and open the people up to dunking.
For example in the case of #2, I recently published the prompts I used to create a terminal MIDI mixer (https://github.com/minimaxir/miditui/blob/main/agent_notes/P...) in the interest of transparency, but those prompts correctly indicate that I barely had an idea how MIDI mixing works and in hindsight I was surprised I didn't get harrassed for it. Given the contentious climate, I'm uncertain how often I will be open-sourcing my prompts going forward.
There's also the lessons on the recent shitstorms in the gaming industry, with Sandfall about Expedition 33's use of GenAI and Larian's comments on GenAI with concept art, where both received massive backlash because they were transparent in interviews about how GenAI was (inconsequentially) used. The most likely consequence of those incidents is that game developers are less likely on their development pipelines.
If your hand is good, throw it down and let the haters weep. If you scared to show your cards, you don't have a good hand and you're bluffing.
In a lesser example, a week ago a Rust developer on Bluesky tried to set up a "Tainted Slopware" list of OSS which used AI, but the criteria for inclusion was as simple as "they accepted an AI-generated PR" and "the software can set up a MCP server." It received some traction but eventually imploded, partially due to the fact that the Linux kernel would be considered slopware due to that criteria.
"Some people expressed disappointment about a thing I think is silly" is literally the center square on the gamer outrage bingo card lol. Same with "someone made a list that I think is kind of stupid".
And again, so what? Why should you care? Again, if you feel that insecure about it, it's you and your work that's the problem, not the haters who are always going to exist. Have the courage of your own convictions or maybe admit that it isn't that strong of a conviction lol.
