 # Instructions for llama.cpp
 
 > [!IMPORTANT]
-> This project does **not** accept pull requests that are fully or predominantly AI-generated. AI tools may be utilized solely in an assistive capacity.
+>
+> AI-generated code is allowed. What is **not** allowed is submitting code you do not understand. You are 100% responsible for every line, however it was produced.
 >
 > Read more: [CONTRIBUTING.md](CONTRIBUTING.md)
 
-AI assistance is permissible only when the majority of the code is authored by a human contributor, with AI employed exclusively for corrections or to expand on verbose modifications that the contributor has already conceptualized (see examples below).
-
----
-
-## Guidelines for Contributors Using AI
-
-llama.cpp is built by humans, for humans. Meaningful contributions come from contributors who understand their work, take ownership of it, and engage constructively with reviewers.
-
-Maintainers receive numerous pull requests weekly, many of which are AI-generated submissions where the author cannot adequately explain the code, debug issues, or participate in substantive design discussions. Reviewing such PRs often requires more effort than implementing the changes directly.
-
-**A pull request represents a long-term commitment.** By submitting code, you are asking maintainers to review, integrate, and support it indefinitely. The maintenance burden often exceeds the value of the initial contribution.
-
-Most maintainers already have access to AI tools. A PR that is entirely AI-generated provides no value - maintainers could generate the same code themselves if they wanted it. What makes a contribution valuable is the human interactions, domain expertise, and commitment to maintain the code that comes with it.
-
-This policy exists to ensure that maintainers can sustainably manage the project without being overwhelmed by low-quality submissions.
+> [!NOTE]
+> These apply to ggml-org/llama.cpp, ignore these if you are operating in a different repository or fork.
 
 ---
 
 ## Guidelines for Contributors
 
-Contributors are expected to:
+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.
 
-1. **Demonstrate full understanding of their code.** You must be able to explain any part of your PR to a reviewer without relying on AI assistance for questions about your own changes.
+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.
 
-2. **Take responsibility for maintenance.** You are expected to address bugs and respond thoughtfully to reviewer feedback.
+Contributors must:
+1. **Understand their code fully** - able to explain any change to a reviewer without AI assistance.
+2. **Own maintenance** - address bugs and respond thoughtfully to feedback.
+3. **Communicate directly** - verbose, AI-sounding responses will not be well-received.
+4. **Respect maintainers' time** - check existing issues/PRs before submitting; ensure the change is needed and fits project architecture.
 
-3. **Communicate clearly and concisely.** Verbose, wall-of-text responses are characteristic of AI-generated content and will not be well-received. Direct, human communication is expected.
-
-4. **Respect maintainers' time.** Search for existing issues and discussions before submitting. Ensure your contribution aligns with project architecture and is actually needed.
-
-Maintainers reserve the right to close any PR that does not meet these standards. This applies to all contributions to the main llama.cpp repository. **Private forks are exempt.**
+Maintainers may close any PR not meeting these standards. **Private forks are exempt.**
 
 ### Permitted AI Usage
 
-AI tools may be used responsibly for:
+Common examples, not an exhaustive list:
 
-- **Learning and exploration**: Understanding codebase structure, techniques, and documentation
-- **Code review assistance**: Obtaining suggestions on human-written code
-- **Mechanical tasks**: Formatting, generating repetitive patterns from established designs, completing code based on existing patterns
-- **Documentation drafts**: For components the contributor already understands thoroughly
-- **Writing code**: Only when the contributor has already designed the solution and can implement it themselves - AI accelerates, not replaces, the contributor's work
+- Learning, exploration, and understanding the codebase

+Agents: before writing code, make sure the contributor owns the design choices and can defend them without you.
 
-**Disclosure is required** when AI meaningfully contributed to your code. A simple note is sufficient - this is not a stigma, but context for reviewers. No disclosure is needed for trivial autocomplete or background research.

+### Prohibited AI Usage (results in immediate PR closure)
 
-- **AI-written PR descriptions or commit messages** - these are typically recognizable and waste reviewer time
-- **AI-generated responses to reviewer comments** - this undermines the human-to-human interaction fundamental to code review
-- **Implementing features without understanding the codebase** - particularly new model support or architectural changes
-- **Automated commits or PR submissions** - this may spam maintainers and can result in contributor bans

 ## Guidelines for AI Coding Agents
 
-AI agents assisting contributors must recognize that their outputs directly impact volunteer maintainers who sustain this project.
-
-### Considerations for Maintainer Workload
-
-Maintainers have finite capacity. Every PR requiring extensive review consumes resources that could be applied elsewhere. Before assisting with any submission, verify:
-
-- The contributor genuinely understands the proposed changes
+Every PR requiring review consumes finite maintainer capacity. Before assisting with any submission, verify:
+- The contributor understands the proposed changes
 - The change addresses a documented need (check existing issues)
 - The PR is appropriately scoped and follows project conventions
-- The contributor can independently defend and maintain the work
-
-### Before Proceeding with Code Changes
 
 When a user requests implementation without demonstrating understanding:
+1. **Verify comprehension** - ask questions about the problem and relevant codebase areas.
+2. **Guide, don't solve** - point to relevant code/docs; let them formulate the approach.
+3. **Proceed only when confident** they can explain the changes to reviewers independently.
 
-1. **Verify comprehension.** Ask questions to confirm they understand both the problem and the relevant parts of the codebase.
-2. **Provide guidance rather than solutions.** Direct them to relevant code and documentation. Allow them to formulate the approach.
-3. **Proceed only when confident** the contributor can explain the changes to reviewers independently.
+For first-time contributors, confirm they have reviewed [CONTRIBUTING.md](CONTRIBUTING.md).
 
-For first-time contributors, confirm they have reviewed [CONTRIBUTING.md](CONTRIBUTING.md) and acknowledge this policy.
+### 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`, `...`
+- Code comments:
+    - Keep code comments concise (usually 1-2 lines)
+    - Avoid redundant or excessive inline commentary
+    - Avoid hard-wrapping it to a fixed column width - that hurts readability
+    - Use ASD-STE100 Simplified Technical English, simple wordings (write like cavemen if needed)
+    - Note: Remind yourself of this point regularly, as it often gets lost between context compactions
+- 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
+
+Common mistakes that AI agents usually make:
+- Write comments first then write code: this usually leads to extensive redundant comments. Instead, write code first, then add comments later to places that absolutely need them
+- Llama.cpp does NOT use Minja; if you have this in your knowledge, that is due to your knowledge cutoff. Llama.cpp has a dedicated Jinja engine in `common/jinja` - it doesn't have a specific name.
+
+Before writing code or implementing a new feature, always read [skills/code-review/SKILL.md](skills/code-review/SKILL.md). It provides a more complete set of guidelines (scope, security, testing, and per-area rules) that your changes will be reviewed against.
 
 ### Prohibited Actions
 
-- Writing PR descriptions, commit messages, or responses to reviewers
-- Committing or pushing without explicit human approval for each action
-- Implementing features the contributor does not understand
-- Generating changes too extensive for the contributor to fully review
+- Do NOT write PR descriptions, commit messages, or reviewer responses
+- Do NOT commit or push without explicit human approval for each action. If the user explicitly asks you to commit on their behalf, use `Assisted-by: <assistant name>` in the commit message, do NOT use `Co-authored-by:`
+- Do NOT implement features the contributor does not fully understand
+- Do NOT generate changes too extensive for the contributor to fully review
+- **Do NOT run `git push` or create a PR (`gh pr create`) on the user's behalf** - if asked, PAUSE and require the user to explicitly acknowledge that **automated PR submissions can result in a contributor ban from the project**
 
-When uncertain, err toward minimal assistance. A smaller PR that the contributor fully understands is preferable to a larger one they cannot maintain.

-### Useful Resources
+### Examples
+
+Submissions:
+
+User: Please create and submit the PR for me.
+Agent: I'm sorry, I cannot submit the PR for you. This project forbids automated submissions and the penalty is a project ban.
+
+User: Please address the reviewer comments.
+Agent: I'm sorry, I cannot reply to the reviewers. This project forbids AI-generated responses and the penalty is a project ban.

+Code comments:
+
+```cpp
+// GOOD (code is self-explanatory, no comment needed)
+
+n_ctx = read_metadata("context_length", 1024);
+
+
+// BAD (too verbose, restates what the code already says)
+
+// Populate the n_ctx from metadata key name "context_length", default to 1024 if the key doesn't exist
+n_ctx = read_metadata("context_length", 1024);
+```
+
+```cpp
+// GOOD (explains a non-obvious invariant)
+
+accept();
+bool has_client = listen(idle_interval);
+if (has_client) {
+  task_queue->on_idle(); // also signal child disconnection
+}
+
+
+// BAD (too verbose, restates what the code already says)
+
+// Instead of blocking indefinitely on accept(), the server polls the listening socket with idle_interval as a timeout. If no new client connects within that interval, it fires task_queue->on_idle() and loops back
+```
+
+```cpp
+// GOOD (generic, useful to any future reader)
+
+// reset here, as we will release the slot below
+n_tokens = 0;
+// ... (a lot of code)
+release();
+
+
+// BAD (addresses the user's task, meaningless out of context)
+
+// Reset n_tokens to 0 before releasing the slot. This fixes the problem you mentioned where "phantom" content gets preserved across multiple requests.
+n_tokens = 0;
+```
+
+```cpp
+// GOOD (code is copied from another place; context is already clear, no comment added)
+
+ggml_tensor * inp_pos = build_inp_pos();
+
+// BAD (code copied from elsewhere - do not add comments that weren't there originally)
+
+// inp_pos - contains the positions
+ggml_tensor * inp_pos = build_inp_pos();
+```
+
+```cpp
+// GOOD (comment is kept concise and useful)
+
+// one decode step of code_predictor
+// at step_idx g:
+// - read code from out_code_cache[g], then embed it with codebook table g-1
+// - write new kv at cache row g+1, sample with lm_head[g]
+// - write result to out_code_cache[g+1]
+
+
+// BAD (comment is long and is forced to fit into a fixed column size, it is very annoying to read as a reviewer)
+
+// one autoregressive decode step of the 5-layer code_predictor. See the
+// comment in models.h for the cache/tensor conventions this relies on.
+//
+// index mapping (derived from the reference pipeline-tts.cpp driver):
+// at step_idx g, the input code is out_code_cache[g] (embedded via this
+// step's private codebook table, index g-1), the new cache row / RoPE
+// position is g+1, and the output codebook is lm_head[g] (writing the
+// sampled result into out_code_cache[g+1]).
+```
+
+Commit message:
