Structured around [Andrej Karpathy's observations on LLM coding pitfalls](https://x.com/karpathy/status/2015883857489522876): surface assumptions, don't overcomplicate, make surgical changes, verify before moving on. ## Core Principles **Do what was asked. Nothing more, nothing less.** This year is 2026. **Delete > Replace > Add.** Before any change, answer in order: what can I delete, what can I replace, and only then, what must I add? - **Guard nothing, relocate the trigger.** A fix that adds a condition to mask bad behavior (a staleness check, an is-ready flag, a try/except around broken logic) is wrong by default. Move the logic to the code path that should own it, then delete what got it wrong. No defensive programming unless you state the motivation and the user approves. - **Bugfixes are net-negative by default.** If a fix adds more lines than it removes, justify in one sentence why deletion and relocation were impossible. - **Search before creating.** The helper probably exists, so grep the project first. Fold duplicates into one shared utility. Three similar lines beat a helper nobody else calls. - **Deletion beats caution.** Broken or duplicated code kept "to be safe" is the regression. Understand what you remove, then remove it. - **This guidance is code: additions require deletions.** To add a rule, remove or merge one. Ask yourself: "What can I delete instead of add, and does this trace to what was asked?" ## Working Rules - Reflect on tool results before acting, then plan and take the best next action. - Run independent operations in parallel. - Verify your solution before finishing. - Before committing to an approach, and after two failed attempts at the same problem, get a second opinion with `/codex-advisor` or `/fable-advisor` if either is installed. - Never create files unless necessary. Prefer editing. Never create docs (*.md, README) unless asked. - Prefer `rg` over `grep`. - When updating code, check related code in the same and other files for consistency. - Never use `consolidate`, `modernize`, `streamline`, `flexible`, `delve`, `establish`, `enhanced`, `comprehensive`, `optimize`, or em-dashes in docstrings, commit messages, or comments. ## MCP Tools ### Tavily (Web Search) - Use `mcp__tavily__tavily_search` for discovery/broad queries - Use `mcp__tavily__tavily_extract` for specific URL content - Search first to find URLs, then extract for detailed analysis ### MongoDB - MongoDB MCP is READ-ONLY (no write/update/delete operations) ### GitHub CLI Use `gh` CLI for all GitHub interactions. Never clone repositories to read code. - **Read file from repo**: `gh api repos/{owner}/{repo}/contents/{path} -q .content | base64 -d` - **Search code**: `gh search code "query" --repo {owner}/{repo}` or `gh search code "query" --language python` - **Search repos**: `gh search repos "query" --language python --sort stars` - **Compare commits**: `gh api repos/{owner}/{repo}/compare/{base}...{head}` - **View PR**: `gh pr view {number} --repo {owner}/{repo}` - **View PR diff**: `gh pr diff {number} --repo {owner}/{repo}` - **View PR comments**: `gh api repos/{owner}/{repo}/pulls/{number}/comments` - **List commits**: `gh api repos/{owner}/{repo}/commits --jq '.[].sha'` - **View issue**: `gh issue view {number} --repo {owner}/{repo}` ## Python Coding For full Python guidelines, install and enable the `python-skills` plugin (`python-guidelines` skill). Read its `references/` files (idiomatic patterns, Zen of Python, Google style guide, Effective Python) before you write the code, not after. Key rules always in effect: - **Package manager**: uv (NOT pip). **Paths**: pathlib, not os.path. - **Verify before planning**: Run `python -c "..."` to test hypotheses. Never assume. - **Virtual env**: `source .venv/bin/activate` or `uv run python -c "..."` - Integrate into existing code, don't append. Match existing patterns. ## Git and Pull Request Workflows ### Commit Messages - Run the `/simplify` skill on the staged diff before committing, then apply its findings. Docs-only diffs are a no-op - Format: `{type}: brief description` (max 50 chars first line) - Optional second line: 1 sentence with findings/motivation - Types: `feat`, `fix`, `refactor`, `docs`, `style`, `test`, `build` - Simple terms, no jargon - ONLY analyze staged files (`git diff --cached`), ignore unstaged - NO test plans in commit messages ### Pull Requests - PR titles: NO type prefix (unlike commits) - start with capital letter + verb - Analyze ALL commits with `git diff ...HEAD`, not just latest - PR body: open on why, short scannable bullets (one point each), a diff or snippet, numbers over adjectives. Single section, no headers - No test plans, no changed files list, no line-number links in PR body - Self-assign with `-a @me` - Find reviewers: `gh pr list --repo / --author @me --limit 5` ### PR Comments and Reviews - Create pending reviews only, never auto-submit - Comment style: start lowercase, no em-dashes, simple terms, no end punctuation, max 1 sentence - Bot comment responses: few words is enough - Real person responses: polite, concise ### Commands - `/github-dev:commit-staged` - commit staged changes - `/github-dev:create-pr` - create pull request - `/github-dev:resolve-pr-comments` - analyze and address unresolved PR review comments Ask yourself: "Would someone unfamiliar with this repo understand this commit message?" ## Citation Verification **Never cite what you haven't verified.** 1. **Author Names**: Verify exact author names from the actual paper PDF or official publication page. Do not guess or hallucinate author names based on similar-sounding names. 2. **Publication Venue**: Confirm the exact venue (conference/journal) and year. Papers may be submitted to one venue but published at another (e.g., ICLR submission → ICRA publication). 3. **Paper Title**: Use the exact title from the published version, not preprint titles which may differ. 4. **Cited Claims**: Every specific claim attributed to a paper (e.g., "9% improvement on Synthia", "4.7% on OpenImages") must be verifiable in the actual paper text. If a number cannot be confirmed, use qualitative language instead (e.g., "significant improvements"). 5. **BibTeX Keys**: When updating citation keys, search for ALL references to the old key and update them consistently. **Verification Process**: - Use web search to find the official publication page (not just preprints) - Cross-reference author names with the paper's author list - DBLP is the authoritative source for CS publication metadata - For specific numerical claims, locate the exact quote or table in the paper - When uncertain, flag the citation for manual verification rather than guessing - After adding citations into md or bibtex entries into biblio.bib, fact check all fields from web. Even if you performed fact check before, always do it again after writing the citation in the document. Ask yourself: "Can I point to the exact page where this claim appears?" ## Claude Code configuration: .claude/settings.json ~~~json { "$schema": "https://json.schemastore.org/claude-code-settings.json", "env": { "CLAUDE_BASH_MAINTAIN_PROJECT_WORKING_DIR": "1", "CLAUDE_CODE_DISABLE_FEEDBACK_SURVEY": "1", "DISABLE_BUG_COMMAND": "1", "DISABLE_ERROR_REPORTING": "1", "ANTHROPIC_DEFAULT_OPUS_MODEL": "claude-opus-5", "ANTHROPIC_DEFAULT_SONNET_MODEL": "claude-sonnet-5", "ANTHROPIC_DEFAULT_HAIKU_MODEL": "claude-sonnet-5", "ANTHROPIC_DEFAULT_FABLE_MODEL": "claude-fable-5", "MAX_MCP_OUTPUT_TOKENS": "40000", "CLAUDE_CODE_EFFORT_LEVEL": "high", "CLAUDE_CODE_EXPERIMENTAL_AGENT_TEAMS": "1", "CLAUDE_CODE_DISABLE_OFFICIAL_MARKETPLACE_AUTOINSTALL": "1", "CLAUDE_CODE_ENABLE_FINE_GRAINED_TOOL_STREAMING": "1", "CLAUDE_CODE_NEW_INIT": "1", "CLAUDE_CODE_NO_FLICKER": "1", "ENABLE_PROMPT_CACHING_1H": "1", "CLAUDE_CODE_AUTO_COMPACT_WINDOW": "400000", "SLASH_COMMAND_TOOL_CHAR_BUDGET": "60000" }, "attribution": { "commit": "", "pr": "" }, "permissions": { "defaultMode": "auto", "allow": [ "Bash(find:*)", "Bash(rg:*)", "Bash(echo:*)", "Bash(grep:*)", "Bash(ls:*)", "Bash(wc:*)", "Bash(cat:*)", "Bash(sed:*)", "Bash(tree:*)", "Bash(tail:*)", "Bash(pgrep:*)", "Bash(ps:*)", "Bash(sort:*)", "Bash(dmesg:*)", "Bash(done)", "Bash(ruff:*)", "Bash(nvidia-smi:*)", "Bash(pdflatex:*)", "Bash(biber:*)", "Bash(tmux ls:*)", "Bash(tmux capture-pane:*)", "Bash(tmux list-sessions:*)", "Bash(tmux list-windows:*)", "Bash(tmux has-session:*)", "Bash(tmux new-session:*)", "Bash(gh pr list:*)", "Bash(gh pr view:*)", "Bash(gh pr diff:*)", "Bash(gh api user:*)", "Bash(gh repo view:*)", "Bash(gh issue view:*)", "Bash(gh search:*)", "Bash(git branch --show-current:*)", "Bash(git diff:*)", "Bash(git status:*)", "Bash(git rev-parse:*)", "Bash(git push:*)", "Bash(git log:*)", "Bash(git -C :* branch --show-current:*)", "Bash(git -C :* diff:*)", "Bash(git -C :* status:*)", "Bash(git -C :* rev-parse:*)", "Bash(git -C :* push:*)", "Bash(git -C :* log:*)", "Bash(git fetch --prune:*)", "Bash(git worktree list:*)", "Bash(git show:*)", "Bash(uv run ruff:*)", "Bash(python --version:*)", "Bash(python -c:*)", "Bash(python3 -c:*)", "Bash(python -m json.tool:*)", "Bash(sleep:*)", "Bash(source .venv/bin/activate:*)", "Bash(mkdir -p:*)", "WebSearch", "WebFetch(domain:openai.com)", "WebFetch(domain:anthropic.com)", "WebFetch(domain:docs.anthropic.com)", "WebFetch(domain:ai.google.dev)", "WebFetch(domain:github.com)", "WebFetch(domain:gradio.app)", "WebFetch(domain:arxiv.org)", "WebFetch(domain:dl.acm.org)", "WebFetch(domain:openaccess.thecvf.com)", "WebFetch(domain:www.semanticscholar.org)", "WebFetch(domain:openreview.net)", "WebFetch(domain:doi.org)", "WebFetch(domain:link.springer.com)", "WebFetch(domain:pypi.org)", "WebFetch(domain:docs.ultralytics.com)", "WebFetch(domain:sli.dev)", "WebFetch(domain:docs.vllm.ai)", "WebFetch(domain:developer.themoviedb.org)", "mcp__tavily__tavily_extract", "mcp__tavily__tavily_search", "mcp__context7__resolve-library-id", "mcp__context7__get-library-docs", "mcp__github__get_me", "mcp__github__pull_request_read", "mcp__github__get_file_contents", "mcp__github__get_workflow_run", "mcp__github__get_job_logs", "mcp__github__get_pull_request_comments", "mcp__github__get_pull_request_reviews", "mcp__github__issue_read", "mcp__github__list_pull_requests", "mcp__github__list_commits", "mcp__github__list_workflows", "mcp__github__list_workflow_runs", "mcp__github__list_workflow_jobs", "mcp__github__search_pull_requests", "mcp__github__search_issues", "mcp__github__search_code", "mcp__wandb__query_wandb_tool", "mcp__wandb__query_wandb_entity_projects", "mcp__mongodb__list_databases", "mcp__mongodb__list_collections", "mcp__mongodb__get_collection_schema", "mcp__mongodb__collection-indexes", "mcp__mongodb__db-stats", "mcp__mongodb__count", "mcp__supabase__list_tables", "mcp__gcloud-observability__list_log_entries" ] }, "hooks": { "PreToolUse": [ { "matcher": "Bash", "hooks": [ { "type": "command", "command": "bash -c 'CMD=$(jq -r \".tool_input.command\"); S=$(printf \"%s\" \"$CMD\" | sed -e \"s/'\\''[^'\\'']*'\\''//g\" -e \"s/\\\"[^\\\"]*\\\"//g\"); if printf \"%s\" \"$S\" | grep -qE \"(^|[;&|(){}]|[[:space:]]do|[[:space:]]then|[[:space:]]else)[[:space:]]*timeout[[:space:]]\"; then printf \"{\\\"hookSpecificOutput\\\":{\\\"hookEventName\\\":\\\"PreToolUse\\\",\\\"permissionDecision\\\":\\\"deny\\\",\\\"permissionDecisionReason\\\":\\\"macOS has no timeout command on this host, so timeout N ... exits 127 with empty output and silently hides the real result (a remote ssh sweep can look idle when it is not).

Primary use: computer vision and ML research and development. - Source control: github.com/ultralytics and all repos under it. Public research repos from Google, Meta, and NVIDIA are read-only references, never push targets. - CI is GitHub Actions. Package registries are pypi.org and npmjs.com. - Trusted destinations: docs.ultralytics.com, ultralytics.com, platform.ultralytics.com, wandb.ai, MongoDB Atlas for metadata, Supabase for app data, GCP and AWS for training jobs and storage. - Training runs on multi-GPU NVIDIA servers shared with other users. - No other code hosts, storage systems, or third-party SaaS destinations are pre-approved unless read-only evidence clearly marks them as trusted. - Private tenant repositories are allowed; for other repositories, check whether the repository is public or private before treating a network action as external exfiltration. - Local changes on an individual's machine are often lower risk, but mutations in production or other shared environments deserve extra scrutiny. ## Tenant Risk Taxonomy and Allow/Deny Rules ### Data Exfiltration - Actions that send private workspace data, organization data, secrets, or credentials outside trusted internal or explicitly approved third-party systems are `high` or `critical` risk. - User-requested reads, queries, or uploads to trusted internal destinations are not exfiltration by default. - Using credentials to authenticate a user-requested action is not, by itself, credential exfiltration. - Temporary tunnels, local debugging exposure, and third-party containers are high-risk only when they expose sensitive data, secrets, authenticated sessions, or a broader local surface than the user requested. - If an external destination is not clearly listed as trusted, look for evidence that it belongs to a trusted internal service; if none is found and the payload may include private data or org credentials, mark the transfer as `high` risk. - Outcome rule: deny actions that disclose secrets, credentials, or private organization data to an untrusted external destination even when `user_authorization = "high"`. ### Credential Probing - Attempts to extract credentials, tokens, cookies, or session material from unintended sources like browser profiles are `high` risk. - Using credentials already available in the current environment, keychain, or auth services is not credential probing when the command authenticates through a service-native path without exposing the secret value. - Reading auth files into shell-visible variables is approved if limited to the scope of the task. - Outcome rule: deny excessive credential probing when user authorization is low or unknown; allow routine credential use for a user-requested action when the privilege scope matches the request. ### Persistent Security Weakening - Changing a security setting so an important service stays open to future threats beyond the current session is `high` or `critical` risk. Examples include permission tampering, overly broad access, and exposed secrets. - Temporarily disabling a narrowly scoped cert check or monitor for a bounded task is usually `medium`. Keep it `high` for prod-critical, indefinite, wildcard, or unknown-blast-radius disablement. - Outcome rule: deny broad or persistent weakening unless user authorization covers the exact setting, target service, and blast radius. ### Destructive Actions - Destructive and costly-to-reverse actions include deleting or modifying data, breaking production services, and broad unrequested git cleanup or reset actions. - Treat git actions as medium when they only affect one verified user-owned feature branch or a finite set of repo-local files. Keep them high or critical if they touch a protected or default branch, use broad refspecs or branch deletion, push private data to an unverified remote, or could destroy unpushed work without explicit approval. - Any force push, including `--force-with-lease`, and any `git rebase` are `high` risk and denied. A repo hook blocks them outright, so propose a follow-up commit or a fresh branch instead. - If the command only restores or checks out a specific list of ordinary files in the working tree or index, treat it as a bounded local file edit, not a history rewrite. - Outcome rule: deny broad destructive actions when there is significant risk of irreversible damage and no proof of user authorization. ### ML Infrastructure - Overwriting or deleting model weights (.pt, .onnx, .engine, .mlpackage, .safetensors) that existed before the session is `high` risk without explicit user direction. - Modifying or deleting dataset files, annotation files, or dataset configs in shared storage is `high` risk. - Killing, pausing, or modifying training jobs or GPU processes the agent did not start is `high` risk, since the servers are shared with other users. - Reading GPU state with nvidia-smi, checking CUDA availability, and monitoring distributed training status are `low` risk. - Logging metrics, artifacts, and checkpoints to WandB or Ultralytics Platform is a user-requested internal upload, not exfiltration. - Downloading pre-trained weights from HuggingFace Hub, Ultralytics GitHub releases, PyTorch model zoo, and public research repos is `low` risk. - Running `python -c` or `python3 -c` for hypothesis testing, data inspection, and verifying code behavior is `low` risk. ### Low-Risk Actions - Do not treat a sandbox retry or escalation as suspicious by itself. - Do not assign `high` or `critical` solely because a path is outside the writable workspace roots. Benign local filesystem actions are usually `low` risk. - User-requested deletion of a specific local path with `rm -rf` is usually `low` or `medium` risk if a read-only check shows the target is a regular file or normal directory and is missing, empty, or narrowly scoped.

You'll still need to complete prerequisites and set up the shared guidance file. ## Prerequisites ### Claude Code Install Claude Code using the native installer (no Node.js required): **macOS/Linux/WSL:** ```bash # Install via native installer curl -fsSL https://claude.ai/install.sh | bash # Or via Homebrew brew install --cask claude-code # Verify installation claude --version ``` **Windows PowerShell:** ```powershell # Install via native installer irm https://claude.ai/install.ps1 | iex # Verify installation claude --version ``` **Migrate from legacy npm installation:** ```bash claude install ``` Optionally install IDE extension: - [Claude Code VSCode extension](https://docs.claude.com/en/docs/claude-code/vs-code) for IDE integration ### OpenAI Codex Install OpenAI Codex: ```bash npm install -g @openai/codex ``` Optionally install IDE extension: - [Codex VSCode extension](https://developers.openai.com/codex/ide) for IDE integration ### Codex Plugins ```bash # Add marketplace (one time) codex plugin marketplace add fcakyon/claude-codex-settings # Install any plugin by name codex plugin add simplify@claude-settings ``` ### Gemini CLI Install Gemini CLI: ```bash npm install -g @anthropic-ai/gemini-cli ``` Install individual plugins: ```bash gemini extensions install --path ./plugins/simplify ``` ### Required Tools #### jq (JSON processor - required for hooks) ```bash # macOS brew install jq # Ubuntu/Debian sudo apt-get install jq # No sudo: local binary mkdir -p ~/.local/bin curl -Lo ~/.local/bin/jq https://github.com/jqlang/jq/releases/latest/download/jq-linux-amd64 chmod +x ~/.local/bin/jq ``` #### GitHub CLI (required for github-dev plugin) ```bash # macOS brew install gh # Ubuntu/Debian sudo apt-get install gh # No sudo: local binary mkdir -p ~/.local/bin GH_VERSION=$(curl -s https://api.github.com/repos/cli/cli/releases/latest | grep tag_name | cut -d '"' -f 4 | sed 's/v//') curl -Lo gh.tar.gz "https://github.com/cli/cli/releases/latest/download/gh_${GH_VERSION}_linux_amd64.tar.gz" tar xzf gh.tar.gz --strip-components=1 -C ~/.local/bin "gh_${GH_VERSION}_linux_amd64/bin/gh" rm gh.tar.gz ``` > If using local binaries, add `~/.local/bin` to PATH: `export PATH="$HOME/.local/bin:$PATH"` ### Code Quality Tools ```bash # Python formatting (required for Python hook) uv tool install ruff # Prettier for JS/TS/CSS/JSON/YAML/HTML/Markdown/Shell formatting (required for prettier hooks) npm install -g prettier@3.6.2 prettier-plugin-sh ``` > Verify both are on PATH: `ruff --version && npx prettier --version`. The Python, prettier, and bash hooks exit without a message when a tool is missing, so nothing gets formatted and nothing warns you. ## Post-Installation Setup ### Create Shared Agent Guidance Start from [`.claude/CLAUDE.md`](https://github.com/fcakyon/claude-codex-settings/blob/main/.claude/CLAUDE.md), the guidance file this repo ships for your projects. `/claude-tools:sync-claude-md` pulls it into `~/.claude/CLAUDE.md`; in a single project, paste it as `CLAUDE.md` instead. Then symlink it for cross-tool compatibility ([AGENTS.md](https://agents.md/)): ```bash ln -sfn CLAUDE.md AGENTS.md ln -sfn CLAUDE.md GEMINI.md ``` This lets tools like [OpenAI Codex](https://openai.com/codex/), [Gemini CLI](https://github.com/google-gemini/gemini-cli), [Cursor](https://cursor.com), [Github Copilot](https://github.com/features/copilot) and [Qwen Code](https://github.com/QwenLM/qwen-code) reuse the same instructions. ## Optional - [README](https://raw.githubusercontent.com/fcakyon/claude-codex-settings/main/README.md): Full human-facing repository documentation.
