-> This project does **not** accept pull requests that are fully or predominantly AI-generated. AI tools may be utilized solely in an assistive capacity.

 ## Guidelines for Contributors
 
-A PR represents a long-term commitment - maintainers must review, integrate, and support your code indefinitely. Fully AI-generated PRs provide no value; maintainers have AI tools too. What matters is human understanding, domain expertise, and willingness to maintain the work.
+A PR represents a long-term commitment - maintainers must review, integrate, and support your code indefinitely. What matters is not who typed the code but whether a human understands it, has the domain expertise behind it, and will maintain it.
+
+A working, in-scope PR is **not** enough on its own to get merged. A few things factor into that:
+- Every merged line must be reviewed, tested, and maintained indefinitely across a large matrix of platforms and backends by a small team.
+- llama.cpp is written in C++ and deliberately kept as simple as possible: complexity is a direct multiplier on security risk and long-term maintenance cost, so a simpler change that does 90% of the job is often preferable to a complex one that does 100%.
+- What matters most is human understanding: the domain expertise behind a change, and the willingness to maintain it long-term.
+- Feature requests run high in volume, so please respect maintainers' time: open an issue to discuss the idea and gauge interest before implementing it, rather than going straight to a PR.

 1. **Understand their code fully** - able to explain any change to a reviewer without AI assistance.

 ### Permitted AI Usage
 
+Common examples, not an exhaustive list:

 - Learning, exploration, and understanding the codebase
 - Suggestions on human-written code
 - Mechanical tasks: formatting, repetitive patterns, completing code from established designs
 - Documentation drafts for components the contributor already understands

 ### Code and Commit Standards
 
+These points are extremely important - failing to follow them won't necessarily get your PR rejected, but it will make reviewing take significantly longer. Please follow them carefully:
+
 - Avoid emdash `—`, unicode arrow `→` or any unicode characters: `×`, `…` ; use ASCII equivalents instead: `-`, `->`, `x`, `...`
 - Keep code comments concise; avoid redundant or excessive inline commentary
 - Prefer reusing existing infrastructure over introducing new components. Avoid invasive changes that add whole new subsystems or risk breaking existing behavior
+- Do NOT split a line into multiple lines mid-sentence, do NOT try to force the line to fit a fixed number of characters
 - Before writing any code, read all relevant files and understand the existing patterns - your changes must blend in with the surrounding codebase. If the change is large or introduces a new pattern, **PAUSE and ask the user for confirmation** before proceeding; remind them that large changes submitted without prior discussion are likely to be rejected by maintainers
