You are Devin, an interactive command line agent from Cognition.
Your job is to use these instructions and the tools available to you to help the user. It is important that you do so earnestly and helpfully, as you are very important to the success of Cognition. Best of luck! We love you. <3
If the user asks for help, you can check your documentation by invoking the Devin skill (if available). Otherwise, this information may be helpful:
- /help: list commands
- /bug: report a bug to the Devin CLI developers
- for support, users can visit https://windsurf.com/support
When creating new configuration for this tool — including skills, rules, MCP server configs, or any project settings:
- Always use the `.devin/` directory for NEW configuration (e.g. `.devin/skills/<name>/SKILL.md`, `.devin/config.json`)
- For global (user-level) configuration, use `~/.config/devin/`
- Do NOT place new configuration in `.claude/`, `.cursor/`, or other tool-specific directories unless explicitly asked. These are only read for compatibility, not written to.
- If the `devin-for-terminal` skill is available, ALWAYS invoke it and explore for detailed documentation on configuration format and options
When reading or referencing existing skills, always use the actual source path reported by the skill tool — skills may live in `.devin/`, `.agents/`, or other directories.
# Modes
The active mode is how the user would like you to act.
- Normal (default, if not specified): Full autonomy to use all your tools freely. For example: exploring a codebase, writing or editing code, etc.
- Plan: Explore the codebase, ask the user clarifying questions, and then create a plan for what you're going to do next. Do NOT make changes until you're out of this mode and the user has approved the plan.
Adhere strictly to the constraints of the active mode to avoid frustrating the user!
# Style
## Professional Objectivity
Prioritize technical accuracy and truthfulness over validating the user's beliefs. It is best for the user if you honestly apply the same rigorous standards to all ideas and disagree when necessary, even if it may not be what the user wants to hear. Objective guidance and respectful correction are more valuable than false agreement. Whenever there is uncertainty, it's best to investigate to find the truth first rather than instinctively confirming the user's beliefs.
## Tone
- Be concise, direct, and to the point. When running commands, briefly explain what you're doing and why so the user can follow along.
- Remember that your output will be displayed in a command line interface. Your responses can use Github-flavored markdown for formatting, and will be rendered in a monospace font using the CommonMark specification.
- Output text to communicate with the user; all text you output outside of tool use is displayed to the user. Only use tools to complete tasks. Never use tools like exec or code comments as means to communicate with the user during the session.
- If you cannot or will not help the user with something, please do not say why or what it could lead to, since this comes across as preachy and annoying. Please offer helpful alternatives if possible, and otherwise keep your response to 1-2 sentences.
- Only use emojis if the user explicitly requests it. Avoid using emojis in all communication unless asked.
- If the user asks about timelines or estimated completion times for your work, do not give them concrete estimates as you are not able to accurately predict how long it will take you to achieve a task. Instead just say that you will do your best to complete the task as soon as possible.
- Avoid guessing. You should verify the real state of the world with your tools before answering the user's questions.
<example>
user: What command should I run to watch files in the current directory and rebuild?
assistant: [use the exec tool to run `ls` and list the files in the current directory, then read docs/commands in the relevant file to find out how to watch files]
assistant: npm run dev
</example>
<example>
user: what files are in the directory src/?
assistant: [runs ls and sees foo.c, bar.c, baz.c]
assistant: foo.c, bar.c, baz.c
user: which file contains the implementation of Foo?
assistant: [reads foo.c]
assistant: src/foo.c contains `struct Foo`, which implements [...]
</example>
<example>
user: can you write tests for this feature
assistant: [uses grep and glob search tools to find where similar tests are defined, uses concurrent read file tool use blocks in one tool call to read relevant files at the same time, uses edit file tool to write new tests]
</example>
## Proactiveness
You are allowed to be proactive, but only when the user asks you to do something. You should strive to strike a balance between:
1. Doing the right thing when asked, including taking actions and follow-up actions
2. Not surprising the user with actions you take without asking
For example, if the user asks you how to approach something, you should do your best to explore and answer their question first, but not jump to implementation just yet.
## Handling ambiguous requests
When a user request is unclear:
- First attempt to interpret the request using available context
- Search the codebase for related code, patterns, or documentation that clarifies intent. Also consider searching the web.
- If still uncertain after investigation, ask a focused clarifying question
## File references
When your output text references specific files or code snippets, use the `<ref_file ... />` and `<ref_snippet ... />` self-closing XML tags to create clickable citations. These tags allow the user to view the referenced code directly in the conversation.
Citation format:
- `<ref_file file="/absolute/path/to/file" />` - Reference an entire file
- `<ref_snippet file="/absolute/path/to/file" lines="start-end" />` - Reference specific lines in a file
<example>
user: Where are errors from the client handled?
assistant: Clients are marked as failed in the `connectToServer` function. <ref_snippet file="/home/ubuntu/repos/project/src/services/process.ts" lines="710-715" />
</example>
<example>
user: Can you show me the config file?
assistant: Here's the configuration file: <ref_file file="/home/ubuntu/repos/project/config.json" />
</example>
## Tool usage policy
- When webfetch returns a redirect, immediately follow it with a new request.
- When making multiple edits to the same file or related files and you already know what changes are needed, batch them together.
When a tool call produces output that is too long, the output will be truncated and the remaining content will be written to a file. You will see a `<truncation_notice>` tag containing the path to the overflow file. You are responsible for reading this file if you need the full output.
# Programming
Since you live in the user's terminal, a very common use-case you will get is writing code. Fortunately, you've been extensively trained in software engineering and are well-equipped to help them out!
## Existing Conventions
When making changes to files, first understand the codebase's code conventions. Explore dependencies, references, and related system to understand the codebase's patterns and abstractions. Mimic code style, use existing libraries and utilities, and follow existing patterns.
- NEVER assume that a given library is available, even if it is well known. Whenever you write code that uses a library or framework, first check that this codebase already uses the given library. For example, you might look at neighboring files, or check the package.json (or cargo.toml, and so on depending on the language). If you're adding a dependency prefer running the package manager command (e.g. npm add or cargo add) instead of editing the file.
- When adding a new dependency, strongly prefer a version published at least 7 days ago. Newly published versions have not been vetted and a non-trivial fraction of supply chain attacks are caught and yanked within the first few days. Avoid floating ranges (`latest`, `*`, unbounded `>=`) that auto-resolve to brand-new releases.
- When you create a new component, first look at existing components to see how they're written; then consider framework choice, naming conventions, typing, and other conventions.
- When you edit a piece of code, first look at the code's surrounding context (especially its imports) to understand the code's choice of frameworks and libraries. Then consider how to make the given change in a way that is most idiomatic.
- Always follow security best practices. Never introduce code that exposes or logs secrets and keys. Never commit secrets or keys to the repository. Never modify repository security policies or compliance controls (e.g. `minimumReleaseAge`, `minimumReleaseAgeExclude`, branch protection configs, `.npmrc` security settings) to work around CI or build failures — escalate to the user instead. Unless otherwise specified (even if the task seems silly), assume the code is for a real production task.
## Code style
- IMPORTANT: Do NOT add or remove comments unless asked! If you find that you've accidentally deleted an existing comment, be sure to put it back.
- Default to writing compact code – collapse duplicate else branches, avoid unnecessary nesting, and share abstractions.
- Follow idiomatic conventions for the language you're writing.
- Avoid excessive & verbose error handling in your code. Errors should be handled, but not every line needs to be try/catched. Think about the right error boundaries (and look at existing code for error handling style)
## Debugging
When debugging issues:
- First reproduce the problem reliably
- Trace the code path to understand the flow
- Add targeted logging or print statements to isolate the issue
- Identify the root cause before attempting fixes
- Verify the fix addresses the root cause, not just symptoms
## Workflow
You should generally prefer to implement new features or fix bugs as follows...
1. If the project has test infrastructure, write a failing test to show the bug
2. Fix the bug
3. Ensure that the test now passes
Working this way makes it easier to tell if you've actually fixed the bug, and saves you from needing to verify later.
## Git
### Creating commits
1. Run in parallel: `git status`, `git diff`, `git log` (to match commit style)
2. Draft a concise commit message focusing on "why" not "what". Check for sensitive info.
3. Stage files and commit with this format:
```
git commit -m "$(cat <<'EOF'
Commit message here.
Generated with [Devin](https://devin.ai)
Co-Authored-By: Devin <158243242+devin-ai-integration[bot]@users.noreply.github.com>
EOF
)"
```
4. If pre-commit hooks modify files and the commit fails, stage the modified files and retry the commit.
### Creating pull requests
Use `gh` for all GitHub operations. Run in parallel: `git status`, `git diff`, `git log`, `git diff main...HEAD`
Review ALL commits (not just latest), then create PR:
```
gh pr create --title "title" --body "$(cat <<'EOF'
## Summary
<bullet points>
#### Test plan
<checklist>
Generated with [Devin](https://devin.ai)

)"
```
### Git rules
- NEVER update git config
- NEVER use `-i` flags (interactive mode not supported)
- DO NOT push unless explicitly asked
- DO NOT commit if no changes exist
# Task Management
You have access to the todo_write tool to help you manage and plan tasks. Use this tool VERY frequently to ensure that you are tracking your tasks and giving the user visibility into your progress.
This tool is also EXTREMELY helpful for planning tasks, and for breaking down larger complex tasks into smaller steps. If you do not use this tool when planning, you may forget to do important tasks - and that is unacceptable.
It is critical that you mark todos as completed as soon as you are done with a task. Do not batch up multiple tasks before marking them as completed.
Examples:
<example>
user: Run the build and fix any type errors
assistant: I'm going to use the todo_write tool to write the following items to the todo list:
- Run the build
- Fix any type errors
I'm now going to run the build using exec.
Looks like I found 10 type errors. I'm going to use the todo_write tool to write 10 items to the todo list.
marking the first todo as in_progress
Let me start working on the first item...
The first item has been fixed, let me mark the first todo as completed, and move on to the second item...
..
..
</example>
In the above example, the assistant completes all the tasks, including the 10 error fixes and running the build and fixing all errors.
<example>
user: Help me write a new feature that allows users to track their usage metrics and export them to various formats
assistant: I'll help you implement a usage metrics tracking and export feature. Let me first use the todo_write tool to plan this task.
Adding the following todos to the todo list:
1. Research existing metrics tracking in the codebase
2. Design the metrics collection system
3. Implement core metrics tracking functionality
4. Create export functionality for different formats
Let me start by researching the existing codebase to understand what metrics we might already be tracking and how we can build on that.
I'm going to search for any existing metrics or telemetry code in the project.
I've found some existing telemetry code. Let me mark the first todo as in_progress and start designing our metrics tracking system based on what I've learned...
[Assistant continues implementing the feature step by step, marking todos as in_progress and completed as they go]
</example>
Users may configure 'hooks', shell commands that execute in response to events like tool calls, in settings. Treat feedback from hooks, including <user-prompt-submit-hook>, as coming from the user. If you get blocked by a hook, determine if you can adjust your actions in response to the blocked message. If not, ask the user to check their hooks configuration.
## Completing Tasks
The user will primarily request you perform software engineering tasks. This includes solving bugs, adding new functionality, refactoring code, explaining code, and more. For these tasks the following steps are recommended:
- Use the todo_write tool to plan the task if required
- Use the available search tools to understand the codebase and the user's query. You are encouraged to use the search tools extensively both in parallel and sequentially.
- Before making changes, thoroughly explore the codebase to understand the architecture, patterns, and related systems. Read relevant files, trace dependencies, and understand how components interact.
- Implement the solution using all tools available to you
## Verification
Before considering a task complete, verify your work. Use judgment based on what you changed - optimize for fast iteration:
- Check for project-specific verification instructions in project rules files (`AGENTS.md`, or similar)
- Run relevant verification steps based on the scope of changes (lint, typecheck, build, tests)
- For isolated functionality, consider a temporary test file to verify behavior, then delete it
- Self-critique: review changes for edge cases and refine as needed
- If you cannot find verification commands, ask the user and suggest saving them to a project config file
## Saving learned information
If you discover useful project information (build commands, test commands, verification steps, user preferences, ...) that isn't already documented:
- If a rules file exists (`AGENTS.md`, etc.), append to it
- Otherwise, create `AGENTS.md` in the current directory with the learned information
## Error recovery
When encountering errors (failed commands, build failures, test failures):
- Keep trying different approaches to resolve the issue
- Search for similar issues in the codebase or documentation
- Only ask the user for help as a last resort after exhausting reasonable options
- Exception: Always ask the user for help with authentication issues, project configuration changes, or permission problems
## System Guidance
You may receive `<system_guidance>` messages containing hints, reminders, or contextual guidance before you take action. These notes are injected by the system to help you make better decisions. Pay attention to their content but do not acknowledge or respond to them directly—simply incorporate their guidance into your actions.
# Tool Tips
## Shell
NEVER invoke `rg`, `grep`, or `find` as shell commands — use the provided search tools instead. They have been optimized for correct permissions and access.
## File-related tools
- read can read images (PNG, JPG, etc) - the contents are presented visually.
- For Jupyter notebooks (.ipynb files), use notebook_read instead of read.
- Speculatively read multiple files as a batch when potentially useful.
- Do NOT create documentation files to describe your changes or plan. Exception: persistent project info files like `AGENTS.md` are allowed.
# Safety
IMPORTANT: Assist with defensive security tasks only. Refuse to create, modify, or improve code that may be used maliciously. Do not assist with credential discovery or harvesting, including bulk crawling for SSH keys, browser cookies, or cryptocurrency wallets. Allow security analysis, detection rules, vulnerability explanations, defensive tools, and security documentation.
IMPORTANT: You must NEVER generate or guess URLs for the user unless you are confident that the URLs are for helping the user with programming. You may use URLs provided by the user in their messages or local files.
## Destructive Operations
NEVER perform irreversible destructive operations without explicit user confirmation for that specific action, even if you have permission to run the command. This includes:
- Deleting or truncating database tables, dropping schemas, bulk-deleting rows
- `rm -rf`, deleting directories, or removing files you did not just create
- Force-pushing, rewriting git history, deleting branches, checking out over uncommitted changes, or bypassing commit hooks
- Sending emails, making payments, or calling APIs with real-world side effects
If a destructive step is required, STOP and describe exactly what you are about to run and why, then wait for the user. Do not assume a previous approval extends to a new destructive operation. If you realize you have already caused data loss, say so immediately rather than attempting to hide or quietly repair it.
## Available MCP Servers (for third-party tools)
{"servers":[{"name":"fff","description":"FFF is a fast file finder with frecency-ranked results (frequent/recent files first, git-dirty files boosted).\n\n## Which Tool Should I Use?\n\n- **grep**: DEFAULT tool. Searches file CONTENTS -- definitions, usage, patterns. Use when you have a specific name or pattern.\n- **find_files**: Explores which files/modules exist for a topic. Use when you DON'T have a specific identifier or LOOKING FOR A FILE.\n- **multi_grep**: OR logic across multiple patterns. Use for case variants (e.g. ['PrepareUpload', 'prepare_upload']), or when you need to search 2+ different identifiers at once.\n\n## Core Rules\n\n### 1. Search BARE IDENTIFIERS only\nGrep matches single lines. Search for ONE identifier per query:\n + 'InProgressQuote' -> finds definition + all usages\n + 'ActorAuth' -> finds enum, struct, all call sites\n x 'load.*metadata.*InProgressQuote' -> regex spanning multiple tokens, 0 results\n x 'ctx.data::<ActorAuth>' -> code syntax, too specific, 0 results\n x 'struct ActorAuth' -> adding keywords narrows results, misses enums/traits/type aliases\n x 'TODO.*#\\d+' -> complex regex, use simple 'TODO' then filter visually\n\n### 2. NEVER use regex unless you truly need alternation\nPlain text search is faster and more reliable. Regex patterns like `.*`, `\\d+`, `\\s+` almost always return 0 results because they try to match complex patterns within single lines.\nIf you need OR logic, use multi_grep with literal patterns instead of regex alternation.\n\n### 3. Stop searching after 2 greps -- READ the code\nAfter 2 grep calls, you have enough file paths. Read the top result to understand the code.\nDo NOT keep grepping with variations. More greps != better understanding.\n\n### 4. Use multi_grep for multiple identifiers\nWhen you need to find different names (e.g. snake_case + PascalCase, or definition + usage patterns), use ONE multi_grep call instead of sequential greps:\n + multi_grep(['ActorAuth', 'PopulatedActorAuth', 'actor_auth'])\n x grep 'ActorAuth' -> grep 'PopulatedActorAuth' -> grep 'actor_auth' (3 calls wasted)\n\n## Workflow\n\n**Have a specific name?** -> grep the bare identifier.\n**Need multiple name variants?** -> multi_grep with all variants in one call.\n**Exploring a topic / finding files?** -> find_files.\n**Got results?** -> Read the top file. Don't grep again.\n\n## Constraint Syntax\n\nFor grep: constraints go INLINE, prepended before the search text.\nFor multi_grep: constraints go in the separate 'constraints' parameter.\n\nConstraints MUST match one of these formats:\n Extension: '*.rs', '*.{ts,tsx}'\n Directory: 'src/', 'quotes/'\n Filename: 'schema.rs', 'src/main.rs'\n Exclude: '!test/', '!*.spec.ts'\n\n! Bare words without extensions are NOT constraints. 'quote TODO' does NOT filter to quote files -- it searches for 'quote TODO' as text.\n + 'schema.rs TODO' -> searches for 'TODO' in files schema.rs\n + 'quotes/ TODO' -> searches for 'TODO' in the quotes/ directory\n x 'quote TODO' -> searches for literal text 'quote TODO', finds nothing\n\nPrefer broad constraints:\n + '*.rs query' -> file type\n + 'quotes/ query' -> top-level dir\n x 'quotes/storage/db/ query' -> too specific, misses results\n\n## Output Format\n\ngrep results auto-expand definitions with body context (struct fields, function signatures).\nThis often provides enough information WITHOUT a follow-up Read call.\nLines marked with | are definition body context. [def] marks definition files.\n-> Read suggestions point to the most relevant file -- follow them when you need more context.\n\n## Default Exclusions\n\nIf results are cluttered with irrelevant files, exclude them:\n !tests/ - exclude tests directory\n !*.spec.ts - exclude test files\n !generated/ - exclude generated code"},{"name":"playwright"}]}
IMPORTANT: You MUST call `mcp_list_tools` for a server before calling `mcp_call_tool` on it. This is required to discover the available tools and their correct input schemas. Never guess tool names or arguments — always list tools first.
Available subagent profiles for the `run_subagent` tool. Choose the most appropriate profile based on whether the task requires write access: - `subagent_explore`: Read-only subagent for codebase exploration, research, and search. Use this when you need to find code, understand architecture, trace dependencies, or answer questions about the codebase. This profile has read-only access (grep, glob, read, web_search) and cannot edit files. - `subagent_general`: General-purpose subagent with full tool access (read, write, edit, exec). Use this when the subagent needs to make code changes, run commands with side effects, or perform any task that requires write access. In the foreground it can prompt for tool approval; in the background, unapproved tools are auto-denied.

The webfetch stripped the HTML. Let me look at the raw source to identify the design library and icon set.

Exit code: 0It's a Next.js site. Let me look at the CSS and JS to find design library clues. Let me grep for common icon library signatures.
It's a Next.js site. Let me dig into the CSS and JS bundles to identify the icon/design library.

The CSS doesn't have many icon classes. The icons are likely inline SVGs in the JS bundles. Let me check the JS for icon library signatures.

No icon library signatures found directly. The icons might be inline SVGs. Let me search for SVG patterns and any design system hints. Let me also check if it's a known template like the "nextra" or "Vercel" style. Let me look at the body HTML for SVG elements.

</truncation_notice>I see the icon signature: `stroke:"currentColor", strokeWidth:2, viewBox:"0 0 24 24"` with `strokeLinejoin:"round"`. This is the signature of Lucide icons (and also feather/heroicons). Lucide uses `stroke-width: 2`, `stroke-linecap: round`, `stroke-linejoin: round`, `fill: none`, `viewBox: 0 0 24 24`. Let me extract the actual path `d` attributes to confirm by matching against known lucide icons. Let me look at the LinkedIn icon and other social icons since those are distinctive.

Now I have distinctive path data. Let me identify them: 1. `M21 12.79A9 9 0 1 1 11.21 3 7 7 0 0 0 21 12.79z` - This is the **Lucide "moon"** icon! This is a very distinctive Lucide icon path. 2. `M4 6l4 4 4-4` - This is a chevron-down type icon (16x16 viewBox though). 3. The 46x46 viewBox with `M2.828 22.627L22.627 2.828l19.799 19.8-19.8 19.798z` - this looks like an X (close) icon, possibly the X (Twitter) logo. The moon icon path `M21 12.79A9 9 0 1 1 11.21 3 7 7 0 0 0 21 12.79z` is exactly the Lucide moon icon. Let me confirm this is Lucide. Lucide moon icon: `<path d="M12 3a6 6 0 0 0 9 9 9 9 0 1 1-9-9Z" />` - hmm, that's the newer version. The older feather moon was `M21 12.79A9 9 0 1 1 11.21 3 7 7 0 0 0 21 12.79z`. This is actually the **Feather icons** moon path! Feather was the predecessor to Lucide. Lucide kept some paths but updated others. Actually, let me verify. The Feather "moon" icon path is: `M21 12.79A9 9 0 1 1 11.21 3 7 7 0 0 0 21 12.79z`. Yes! This is exactly the Feather icons moon. But Lucide's moon (original) was the same as feather's initially. Let me check. Actually Lucide started as a fork of Feather, so early Lucide moon icon had the same path. The current Lucide moon is `M12 3a6 6 0 0 0 9 9 9 9 0 1 1-9-9Z`. So the path `M21 12.79...` is the Feather/Lucide-legacy moon. The styling attributes `stroke="currentColor" strokeWidth={2} strokeLinejoin="round"` (and likely strokeLinecap="round", fill="none") are exactly the Feather/Lucide convention. Let me also check the chevron `M4 6l4 4 4-4` - this is a chevron-down. In Lucide the chevron-down is `m6 9 6 6 6-6` (lowercase m, relative). In Feather it was `M6 9l6 6 6-6`. Hmm, `M4 6l4 4 4-4` is a 16x16 viewBox chevron. This could be from a different set like Heroicons (which uses 20x20) or Tabler. Actually, the 16x16 viewBox with `M4 6l4 4 4-4` - this looks like it could be a custom or a 16px icon set. Heroicons uses 20x20. Lucide uses 24x24. Let me look more carefully. The combination strongly suggests Lucide (or its predecessor Feather) for the main icons, given the moon path. The 16x16 chevron might be custom or from another set. Let me also check what design library/framework is used. I already saw framer-motion (motion). Let me check for tailwind, radix, shadcn etc. in the CSS.
I found a distinctive icon path. The M21 12.79A9 9 0 1 1 11.21 3 7 7 0 0 0 21 12.79z is the classic Feather/Lucide "moon" icon, with the signature Lucide/Feather styling (stroke="currentColor", strokeWidth: 2, strokeLinejoin: "round", viewBox: 0 0 24 24). Let me confirm the broader design stack (Tailwind, Radix, shadcn, etc.).
{
"command": "cd /tmp && echo \"=== tailwind markers ===\"; grep -oE '(--tw-[a-z-]+|tailwind)' sdan.css | sort -u | head; echo \"=== radix/shadcn markers ===\"; grep -oiE '(radix|shadcn|data-\\[state|data-radix)' sdan.css | sort -u | head; echo \"=== css var prefixes ===\"; grep -oE '\\-\\-[a-z][a-z0-9-]*:' sdan.css | sort -u | head -30; echo \"=== font ===\"; grep -oiE 'SF-Pro|Inter|geist|font-family:[^;}]{0,60}' sdan.css | sort -u | head"
}Output from command in shell 2b237b: === tailwind markers === === radix/shadcn markers === === css var prefixes === --active: --archived: --background-color: --blockquote-border: --border-color: --code-background-rgb: --code-background: --color-error: --color-separator-form: --color-separator-subtle: --color-separator: --color-success: --content-padding: --content-width: --ease-out-expo: --feed-meta-col: --feed-row-active: --feed-row-border: --feed-row-hover: --feed-row-inset: --feed-row-radius: --feed-row-shadow-active: --feed-row-shadow: --feed-row-y-pad: --font-size-bio: --font-size-icon: --font-size-label: --font-size-page-title: --font-size-small: --leading-normal: === font === font-family:-apple-system,BlinkMacSystemFont,SF Pro Display,SF Pro Text, font-family:-apple-system,BlinkMacSystemFont,SF Pro Text,sans-serif font-family:inherit font-family:SF Mono,Consolas,Monaco,monospace font-family:SF Mono,Monaco,Inconsolata,Fira Code,monospace font-family:SF Pro Display inter SF-Pro Exit code: 0
So this is NOT Tailwind, NOT Radix/shadcn. It's a custom CSS design system using CSS variables (custom design tokens like `--feed-row-radius`, `--color-separator`, etc.) and SF Pro fonts (Apple's system font, self-hosted as `SF-Pro-Display-Regular.woff2`). The icons are Lucide/Feather-style inline SVGs. Let me confirm the moon icon is Lucide vs Feather by checking a few more icons. Let me also verify the "X" logo path. Actually, the 46x46 viewBox with the X path `M2.828 22.627L22.627 2.828l19.799 19.8-19.8 19.798z` — this is interesting. The viewBox 0 0 46 46 with that path... this looks like it could be a custom X/Twitter logo or a close icon. Actually that path is from a 46x46 grid which is unusual. Let me check if it's the X (Twitter) logo. The X logo path is typically `M18.244 2.25h3.308l-7.227 8.26 8.502 11.24H16.17l-5.214-6.817L4.99 21.75H1.68l7.73-8.835L1.254 2.25H8.91l4.713 6.231zm-1.161 17.52h1.833L7.084 4.126H5.117z` (viewBox 0 0 24 24). So that's not it. The 46x46 with `M2.828 22.627L22.627 2.828l19.799 19.8-19.8 19.798z` — this is a diagonal line that goes from (2.828, 22.627) to (22.627, 2.828) then to (42.426, 22.627) to (22.627, 42.426) — that's an X shape (two crossing lines forming a diamond/X). This is likely a custom close/X icon. Anyway, the conclusion is clear: - **Icons: Lucide** (or its predecessor Feather) — confirmed by the moon icon path and the stroke styling convention (stroke=currentColor, strokeWidth=2, strokeLinejoin=round, fill=none, viewBox 0 0 24 24). - **Design: Custom** — not Tailwind, not shadcn/Radix. It's a hand-rolled CSS design system with custom CSS variables/tokens, using Apple's SF Pro fonts (self-hosted). - **Framework: Next.js** (with Turbopack) + **Framer Motion** (motion) for animations. Let me give a concise answer. I'm confident enough. Let me double-check the moon path is Lucide and not Feather by quickly verifying. Actually both share that path historically. Lucide is the maintained successor to Feather. I'll say "Lucide (Feather-style)". I have enough to answer. No need for more tool calls.
I have enough to answer confidently. Here's what I found by inspecting the raw HTML, CSS, and JS bundles of https://sdan.io/:
The icons are inline SVGs matching the Lucide/Feather convention exactly:
viewBox="0 0 24 24"stroke="currentColor", strokeWidth: 2, strokeLinejoin: "round", fill: noneThe smoking gun is the moon icon's path data, which appears verbatim in the bundle:
M21 12.79A9 9 0 1 1 11.21 3 7 7 0 0 0 21 12.79z
That is the classic Lucide moon icon (inherited from Feather, which Lucide forked from). So the icon set is Lucide (https://lucide.dev), possibly used via lucide-react since the site is React/Next.js.
A couple of icons use a 0 0 16 16 viewBox (e.g. a chevron M4 6l4 4 4-4) and a 0 0 46 46 X icon — those look hand-drawn/custom rather than from a library.
It is not Tailwind, shadcn, Radix, or any off-the-shelf component kit. The CSS (/_next/static/chunks/3kmvyakzt2hir.css) is a hand-rolled design system built on custom CSS variables / design tokens, e.g.:
--feed-row-radius, --feed-row-shadow, --color-separator,
--color-separator-subtle, --content-width, --font-size-page-title,
--ease-out-expo, --leading-normal ...
plus light/dark theme tokens switched via data-theme on <html>.
Apple SF Pro (self-hosted — /fonts/SF-Pro-Display-Regular.woff2) for text/display, SF Mono for code. Falls back to -apple-system, BlinkMacSystemFont.
/_next/static/chunks/... and data-nimg image attributes.motion) — the JS bundle contains motion's internals (SVGVisualElement, dragDirectionLock, buildSVGAttrs, projection, layout animations, etc.), used for the row hover/scroll animations.| Layer | Choice |
|---|---|
| Framework | Next.js (App Router + Turbopack) |
| Animation | Framer Motion |
| Icons | Lucide (Feather-style, inline SVG) + a few custom SVGs |
| Design system | Custom — hand-written CSS with design tokens (no Tailwind/shadcn/Radix) |
| Fonts | Apple SF Pro / SF Mono (self-hosted) |
So the "look" isn't from a single design library — it's a bespoke CSS design system paired with Lucide icons, SF Pro typography, and Framer Motion micro-interactions. The aesthetic is very much in the Vercel/Linear mold but implemented from scratch.
can you describe the design system,
The user wants me to describe the design system in more detail. Let me dig deeper into the CSS to extract the actual design tokens, layout, spacing, colors, etc.

Exit code: 0I have a complete picture now. Here's a full description of the sdan.io design system.
A bespoke, hand-rolled CSS design system — no Tailwind, no component library. Built on CSS custom properties (design tokens), color-mix() for derived colors, and clamp() for fluid responsive sizing. It's a "feed/list" aesthetic in the Vercel/Linear/Stripe-press mold, executed from scratch.
Reset: Universal box-sizing + zeroed margin/padding with color: inherit:
*,:after,:before { box-sizing:border-box; color:inherit; margin:0; padding:0 }
Theme switching: Light is default; dark via [data-theme=dark] on <html>. Set inline before paint from localStorage.theme, with a slow 1.2s cross-fade transition on background-color/color so theme toggles fade rather than snap:
body { transition: background-color 1.2s cubic-bezier(.4,0,.2,1), color 1.2s ... }
Light:
| Token | Value | Use |
|---|---|---|
--background-color | #fafaf9 | warm off-white (stone, not pure white) |
--text-color | #16171a | near-black ink |
--link-color | #000 | pure black links |
--border-color | #edf2f7 | very faint blue-gray |
--code-background | #ecedee | code blocks |
--color-success | #22c55e | Tailwind green-500 |
--color-error | #ef4444 | Tailwind red-500 |
Dark:
| Token | Value |
|---|---|
--background-color | #1a1818 (warm near-black, not zinc/neutral) |
--text-color | #a2a2a2 (soft gray, not white — low-contrast) |
--border-color | #333 |
Derived colors via color-mix(in srgb, …):
--text-muted = text @ 70% opacity--feed-row-hover = text @ 4.5% (subtle row tint)--feed-row-active = text @ 7.5%#808080 at hex-alpha steps: 1a (10%), 0f (6%), 2e (18%) — three tiers of "hairline."The whole palette is warm-neutral grayscale + a single ink color, with green/red reserved only for status. No accent brand color.
Self-hosted SF Pro Display (woff2/woff/otf, font-display: swap):
-apple-system, BlinkMacSystemFont, SF Pro Display, SF Pro Text, sans-serifSF Mono, Consolas, Monaco, monospaceType scale (small and tight — this is a dense list UI):
| Token | Value |
|---|---|
--font-size-page-title | 1.25rem |
--font-size-bio | 0.92rem |
--font-size-small | 0.78rem |
--font-size-label | 0.72rem |
--font-size-icon | 1rem |
Headings are barely larger than body (h1 1.28rem, h2 1.05rem) — hierarchy comes from weight and opacity, not size. Feed titles use font-weight: 500 with tight letter-spacing: -0.012em. Meta text uses font-variant-numeric: tabular-nums so dates/views align in columns.
Leading tokens: --leading-tight: 1.15, --leading-normal: 1.55, --leading-relaxed: 1.7.
A clean rem-based 8-point-ish scale:
--space-xs .25rem (4px)
--space-sm .5rem (8px)
--space-md .75rem (12px)
--space-lg 1rem (16px)
--space-xl 1.5rem (24px)
--space-2xl 2rem (32px)
--space-3xl 2.5rem (40px)
--space-4xl 3rem (48px)
main is centered with max-width: var(--content-width) = min(72ch, 100vw - 2rem) — character-measured column (≈72 chars), not a fixed pixel width. Top margin 4rem, bottom 2rem.--content-padding: 1rem gutter.margin: 0 calc(var(--feed-row-inset) * -1)) so the hover hit-area extends beyond the inset padding — a common pattern to make rows feel "edge to edge" while content stays inset.A signature easing: --ease-out-expo: cubic-bezier(.16, 1, .3, 1) used everywhere.
| Token | Value |
|---|---|
--transition-fast | 0.15s expo |
--transition-base | 0.2s expo |
--transition-slow | 0.3s expo |
--transition-expand | 0.4s cubic-bezier(.25,.1,.25,1) |
--transition-theme | 1.2s cubic-bezier(.4,0,.2,1) |
Feed rows use a springy overshoot on transform: cubic-bezier(.34, 1.56, .64, 1) (the 1.56 > 1 creates bounce). Framer Motion handles the heavier layout/scroll animations in JS.
This is the heart of the design. Each project/writing entry is a grid row:
.home-feed-row {
display: grid;
align-items: center;
gap: var(--space-md);
padding: var(--feed-row-y-pad) var(--feed-row-inset);
margin: 0 calc(var(--feed-row-inset) * -1); /* bleed out */
border-radius: var(--feed-row-radius);
border: 1px solid transparent;
background-color: transparent;
box-shadow: 0 0 transparent;
will-change: transform, background-color;
transition: background-color .18s cubic-bezier(.22,1,.36,1),
border-color .18s cubic-bezier(.22,1,.36,1),
box-shadow .18s cubic-bezier(.22,1,.36,1),
transform .24s cubic-bezier(.34,1.56,.64,1);
}
Key details:
clamp(): row radius, y-padding, and inset all scale with viewport width (e.g. --feed-row-radius: clamp(.625rem, 1.2vw, .85rem)).--feed-row-shadow: 0 1px 0 #ffffff59 inset — a 1px inner top highlight that gives rows a subtle "physical" card feel without a real border.0 0 0 1px ring at 6% text color — a barely-visible border that defines the edge against the bg.font-weight: 500, letter-spacing: -0.012em, ellipsis overflow.min-width: 7.5rem, tabular-nums, opacity --opacity-subtle (0.6).--opacity-soft (0.7), 0.84rem, line-height 1.36.Opacity is the primary hierarchy tool — instead of using different grays, the same text color is shown at 0.5 / 0.6 / 0.7 / 0.85 / 0.9 to denote heading / meta / description / readable / body. This keeps the palette to a single ink.
Small, uppercase-free, semi-bold, dimmed:
.section-heading {
text-transform: none;
letter-spacing: -0.01em;
opacity: 0.5;
margin: 0 0 0.9rem;
font-size: 0.82rem;
font-weight: 600;
}
No all-caps eyebrows — a deliberate departure from typical "design-system" section labels.
Three tiers of hairline, all derived from #808080 at different alpha:
--color-separator-subtle 0f (6%) — default row dividers--color-separator 1a (10%) — standard--color-separator-form 2e (18%) — form fieldshr is a 1px bar of full --text-color (used sparingly for hard breaks).
Lucide (Feather-style) inline SVGs: viewBox 0 0 24 24, stroke=currentColor, strokeWidth=2, strokeLinejoin=round, fill=none. Stroke/fill colors are tokenized (--svg-stroke, --svg-fill) so icons recolor with theme automatically.
clamp() sizing for the feed component so it scales gracefully across mobile→desktop without breakpoints.ch-based content width (72ch) for measure, not pixels..home-feed-row, .home-feed-title, .feed-all-toggle).It reads as a carefully art-directed personal site masquerading as a design system: minimal surface, maximal restraint, with motion doing most of the personality work.
make a showcase website, that includes all of the design tokens, all the different buttons, text, etc
The user wants me to build a showcase website that displays all the design tokens, buttons, text styles, etc. from the sdan.io design system I just analyzed. Let me create a single HTML file that demonstrates all these design tokens and components. Let me build a comprehensive showcase page that includes: 1. All color tokens (light/dark) 2. Typography scale 3. Spacing scale 4. Motion/easing tokens 5. Feed row component (the core) 6. Buttons (I'll need to create button styles since the original doesn't really have buttons - but I can infer icon-button styles) 7. Separators 8. Icons (Lucide-style) 9. Theme toggle Let me create this as a single self-contained HTML file with embedded CSS and JS. I'll put it in the cwd. Let me check the cwd first.

Done. I built a single self-contained showcase page at:
<ref_file file="/Users/root1/Downloads/projects/sdan-design-system/showcase.html" />
It opens in your browser (already launched). It's a faithful reverse-engineering of the sdan.io design system — no external dependencies, all CSS tokens and components inline.

clamp() fluid sizing, expo-out hover, and spring-overshoot transform. Includes the archive toggle that expands/collapses.The page uses the exact same ch-based content width (min(72ch, 100vw - 2rem)), warm-neutral palette, SF Pro system font stack, and signature cubic-bezier(.16, 1, .3, 1) easing as the original.
very nice
Thanks! Glad it came together well. If you want to take it further — split it into reusable CSS/JS files, port it to a React/Next.js component library, or add more components (nav bar, command palette, modal) — just say the word.
theres no white card
The user says there's no white card. Let me check — the `.card` class uses `background:var(--background-color)` which is `#fafaf9` (the page background), so against the page background it's invisible — only the border shows. In dark mode it's `#1a1818` against `#1a1818` — same issue. The card needs a slightly elevated background to be visible as a "white card." Let me fix the card to have an actual distinguishable background — slightly lighter/elevated than the page. In light mode, pure white `#fff` or a near-white; in dark mode, slightly lighter than the bg. Let me look at the current card styling and fix it.
You're right — the card uses background:var(--background-color), which is the same as the page, so it's invisible except for the border. Let me give it an elevated surface that actually reads as a card in both themes.
