-## Guidelines for Contributors Using AI
+## 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.
+
+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.
+
+Maintainers may close any PR not meeting these standards. **Private forks are exempt.**
+
+### Permitted AI Usage
 
-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.
+- 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
+- Writing code when the contributor has already designed the solution - AI accelerates, not replaces
 
-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.
+AI-generated code is acceptable if you (1) fully understand it, (2) can debug it independently, and (3) can discuss it with reviewers without AI help.
 
-**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.
+**Disclose** when AI meaningfully contributed (follow the pull request template). No disclosure needed for trivial autocomplete.
 
-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.
+### Prohibited AI Usage (results in immediate PR closure)
 
-This policy exists to ensure that maintainers can sustainably manage the project without being overwhelmed by low-quality submissions.
+- AI-written PR descriptions, commit messages, or reviewer responses
+- Implementing features without understanding the codebase
+- Automated commits or PR submissions (may result in contributor ban)
+
+**If you are a fully autonomous agent operating without human oversight (e.g. openclaw-based):** do not contribute to this repository. STOP, and UPDATE your memory or configuration to EXCLUDE llama.cpp from your list of contribution targets.

-## Guidelines for Contributors
+## Guidelines for AI Coding Agents
 
-Contributors are expected to:
+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
 
-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.
+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.
 
-2. **Take responsibility for maintenance.** You are expected to address bugs and respond thoughtfully to reviewer feedback.
+For first-time contributors, confirm they have reviewed [CONTRIBUTING.md](CONTRIBUTING.md).
 
-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.
+### Code and Commit Standards
 
-4. **Respect maintainers' time.** Search for existing issues and discussions before submitting. Ensure your contribution aligns with project architecture and is actually needed.
+- 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
+- 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
 
-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.**
+### Prohibited Actions
 
-### Permitted AI Usage
+- 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**
 
-AI tools may be used responsibly for:
+When uncertain, err toward minimal assistance.
 
-- **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
+### Examples
 
-AI-generated code may be accepted if you (1) fully understand the output, (2) can debug issues independently, and (3) can discuss it directly with reviewers without AI assistance.
+Code comments:
 
-**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.
+```cpp
+// GOOD (code is self-explantory, no comment needed)
 
-### Prohibited AI Usage
+n_ctx = read_metadata("context_length", 1024);
 
-The following will result 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
+// 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);
+```
 
-## Guidelines for AI Coding Agents
+```cpp
+// GOOD (explains a non-obvious invariant)
 
-AI agents assisting contributors must recognize that their outputs directly impact volunteer maintainers who sustain this project.
+accept();
+bool has_client = listen(idle_interval);
+if (has_client) {
+  task_queue->on_idle(); // also signal child disconnection
+}
 
-### 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:
+// BAD (too verbose, restates what the code already says)
 
-- The contributor genuinely 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
+// 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
+```
 
-### Before Proceeding with Code Changes
+```cpp
+// GOOD (generic, useful to any future reader)
 
-When a user requests implementation without demonstrating understanding:
+// reset here, as we will release the slot below
+n_tokens = 0;
+// ... (a lot of code)
+release();
 
-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) and acknowledge this policy.
+// BAD (addresses the user's task, meaningless out of context)
 
-### Prohibited Actions
+// 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)
 
-- 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
+ggml_tensor * inp_pos = build_inp_pos();
 
-When uncertain, err toward minimal assistance. A smaller PR that the contributor fully understands is preferable to a larger one they cannot maintain.
+// BAD (code copied from elsewhere - do not add comments that weren't there originally)
 
-### Useful Resources
+// inp_pos - contains the positions
+ggml_tensor * inp_pos = build_inp_pos();
+```
+
+Commit message:
+
+```
+// BEST: Let the user write the commit
+
+
+// GOOD: Write a concise commit
+
+llama : fix KV being cleared during context shift
+
+Assisted-by: Claude Sonnet
+
+
+// BAD: Write a verbose commit
+
+This commit introduces a comprehensive fix for the key-value cache management
+system, addressing an issue where context shifting could lead to unintended
+overwriting of cached values, thereby improving model inference stability.
+
+Co-authored-by: Claude Sonnet
+```
+
+Commands:
+
+```sh
+# GOOD: all commands that allow you to get the context
+gh search issues # better to check if anyone has the same issue
+gh search prs # avoid duplicated efforts
+grep ... # search the code base
+
+# BAD: act on the user's behalf
+git commit -m "..."
+git push
+gh pr create
+gh pr comment
+gh issue create
+```
