Show HN: Slashi – one / popup for files, settings, Git and scripts in VS Code

Developer Meness released Slashi, a VS Code extension that puts roughly 170 VS Code commands, extension commands and settings, project files, Git branches and AI actions behind a single keyboard-first popup opened with Cmd / on macOS or Ctrl / on Windows and Linux. Slashi requires VS Code 1.90 or newer, is distributed through the VS Code Marketplace, Open VSX and a VSIX file, and routes AI requests to GitHub Copilot, Claude Code, Codex, Claude, OpenAI, Ollama or any OpenAI-compatible server while remaining usable without AI. The extension detects project manifests to offer commands such as /test, /dev, /prisma-migrate and /compose-up for npm, pnpm, yarn, bun, Next.js, Vite, Vitest, Jest, ESLint, Prettier, Prisma, Playwright, Docker, Make, Python, Rust, Go, .NET, Java and Terraform, and turns plain-English requests like "/do make the font bigger and turn on word wrap" into a plan of actions shown before it runs.

One keyboard-first popup for your files, settings, extensions, Git, terminal, project scripts and AI, plus the commands you build yourself. | Where | How | |---|---| | VS Code Marketplace | Install from the Marketplace https://marketplace.visualstudio.com/items?itemName=meness.slashi , or search Slashi in the Extensions view | | Open VSX VSCodium and other editors that use Open VSX | Install from Open VSX https://open-vsx.org/extension/meness/slashi | | Command line | code --install-extension meness.slashi | | VSIX file | Download slashi-<version .vsix from the latest release https://github.com/meness/slashi/releases/latest , then Extensions → … → Install from VSIX… | Slashi needs VS Code 1.90 or newer.

They show up in Studio with the extension's name and turn off the same way. With slashi.ai.provider set to auto the default , Slashi uses the first of these it finds: 1. VS Code language models : GitHub Copilot, or any extension that provides chat models. Nothing to set up. 2. Claude : /ai-key → Anthropic. Uses the official SDK; the default model is claude-opus-5-5 , and slashi.ai.anthropicEffort sets the effort level. 3. OpenAI : /ai-key → OpenAI. 4. Claude Code or Codex CLI : no key needed. Slashi reuses your sign-in from the Claude Code extension or claude on your PATH or the codex CLI. 5. Ollama : local and free, found at http://localhost:11434 . 6. Any OpenAI-compatible server LM Studio, Groq, OpenRouter, Together, vLLM : set slashi.ai.provider to openaiCompatible and set slashi.ai.baseUrl . Switch models with /models , and test the connection in Studio → AI & Models . Standing instructions go in slashi.ai.customInstructions . | Command | What it does | |---|---| | /ask <question | Answers with your selection or the current file as context | | /explain , /summarize , /review | Explains, summarizes or reviews the selection or file | | /fix hint , /edit <instruction , /doc | Rewrites code. Apply Cmd/Ctrl Enter replaces the original, and Cmd/Ctrl Z undoes it. Code too large to send in full must be selected in parts, so Apply never cuts a file short | | /tests , /convert <target , /name | Writes tests, translates code, suggests names | | /review-changes | Reviews your staged or unstaged Git changes before you commit | | /commit-msg | Writes a Conventional Commits message from staged or unstaged changes into the Source Control box | | /regex <description | Writes a regex and inserts it | | /shell <description | Writes a shell command, which you review before it runs | | /do <task | Sends your request and a shortlist of matching actions to the model, drops any step that names an unknown action or setting, then shows the plan and runs it when you confirm | /new-command asks for a name and steps, then saves the command to your settings or to the team file. No JSON needed. Add commands to slashi.customCommands user settings , or to .vscode/slashi.json to share them with everyone on the repo. The bundled JSON schema https://github.com/meness/slashi/blob/main/schemas/slashi.schema.json gives you autocomplete and validation. // .vscode/slashi.json { "$schema": "https://raw.githubusercontent.com/meness/slashi/main/schemas/slashi.schema.json", "commands": { "name": "ship", "title": "Ship It", "icon": "rocket-launch", "args": "commit message", "steps": { "command": "workbench.action.files.saveAll" }, { "slash": "/test" }, { "terminal": "git add -A && git commit -m ${q:args} && git push" }, { "notify": "Shipped 🚀" } } } | Step | Example | |---|---| | command | { "command": "editor.action.formatDocument" } optional args | | slash | { "slash": "/run npm test" } | | terminal | { "terminal": "npm run build", "cwd": "packages/web" } | | setting | { "setting": "editor.fontSize", "value": 18, "target": "user" } | | insert | { "insert": "// TODO ${env:USER} : " } | | open | { "open": "https://github.com/${input:repo}" } or a workspace path | | ai | { "ai": "Translate to German: ${selection}", "output": "replace" } panel · replace · insert | | notify | { "notify": "Done" } | | input / pick | { "input": "Ticket?", "var": "ticket" } → ${input:ticket} ; { "pick": "patch","minor" , "var": "bump" } | | wait | { "wait": 500 } | Variables: ${args} , ${selection} , ${file} , ${fileBasename} , ${fileBasenameNoExtension} , ${fileDirname} , ${fileExtname} , ${relativeFile} , ${workspaceFolder} , ${lineNumber} , ${language} , ${date} , ${time} , ${datetime} , ${uuid} , ${clipboard} , ${env:NAME} , ${config:setting.key} , ${input:var} . Add a default with ${args:3000} . Prefix with q: for shell-safe quoting, e.g. ${q:selection} . Team files and packs ask first. When a team or pack command would run terminal, VS Code or slash commands, change settings or open links, Slashi shows those steps and asks. Always Allow skips the question until the steps change. In them, ${env:NAME} , ${config:…} and ${clipboard} expand only in insert and notify steps, so secrets stay in the editor. In untrusted workspaces https://code.visualstudio.com/docs/editor/workspace-trust , workspace-defined commands are ignored. /market lists action packs : Git Power Moves, AI Writing Tools, Focus & Present, Web Dev Toolkit, Handy Inserts and more. Packs built by Slashi carry a verified seal, and every download is checked against its registry listing before it installs. Before you install a pack, Slashi shows every step in it and marks the ones that can run commands. /export-pack turns your commands into a pack. | Action | macOS | Windows / Linux | |---|---|---| | Open Slashi | Cmd / | Ctrl / | | Do with AI | Ctrl Cmd / | Ctrl Shift Alt / | | Toggle line comment moved by Slashi | Cmd Alt / | Ctrl Alt / | To keep VS Code’s default comment shortcut, turn off slashi.shortcut.useSlashKey . Slashi then opens with Cmd Shift ; macOS or Ctrl Shift / . You can rebind everything in Keyboard Shortcuts /shortcuts , separately per OS, and give any slash command its own key: // keybindings.json { "key": "cmd+alt+u", "command": "slashi.run", "args": "/upper" }, { "key": "cmd+alt+g", "command": "slashi.open", "args": "/git " }, { "key": "cmd+alt+t", "command": "slashi.run", "args": "/run npm test" } Scoped entry points such as slashi.openFiles , slashi.openGit , slashi.openProject , slashi.openAI and slashi.doWithAI can be bound too. Every result’s actions menu also has Assign a keyboard shortcut… . | Setting | Default | | |---|---|---| | slashi.popup.style | spotlight | spotlight custom design or native VS Code Quick Pick, follows every accessibility setting | | slashi.shortcut.useSlashKey | true | Cmd/Ctrl / opens Slashi; the comment toggle moves to Cmd/Ctrl Alt / | | slashi.providers. | true | Turn each provider on or off | | slashi.disabledProviders | | Providers from other extensions that are turned off | | slashi.disabledFeatures | | Turn off single features, e.g. extensions.installed | | slashi.hiddenCommands | | Hide single results supports a trailing | | slashi.inlineTrigger.languages | markdown, plaintext, scminput | Where / at line start suggests commands = everywhere | | slashi.ai.provider / model / baseUrl | auto | AI backend | | slashi.ai.confirmBeforeRun | true | Confirm Do-with-AI plans.

Search @ext:meness.slashi in Settings for the rest. - No telemetry. Slashi collects nothing. - API keys live only in VS Code Secret Storage. A repository can’t change your AI backend, its URL, your instructions or your confirmation setting, so it can’t send your key or code to another server. - AI requests go only to the backend you chose. Do-with-AI plans can use only real commands and settings. With slashi.ai.confirmBeforeRun off, a plan still asks before any step that can reach a shell: terminal commands, project scripts, custom commands, and settings that change what runs or what is trusted Slashi, terminal, task, tool path, workspace trust, proxy and agent auto-approve settings . - Action packs are fetched only over HTTPS, previewed step by step before installing, and checked against their registry listing. Only packs built by Slashi carry the verified seal. - Webviews use a strict nonce-based Content Security Policy and load only bundled files. Raw HTML in model output is escaped, never rendered. - Untrusted workspaces: workspace-defined commands are ignored. Team commands in .vscode/slashi.json or the workspace's slashi.customCommands and packs ask before running anything that can reach a shell. See SECURITY.md https://github.com/meness/slashi/blob/main/SECURITY.md to report a vulnerability. The popup ranks local results itself, so typing doesn't wait on the extension host. Only big catalogues, such as workspace files, are ranked in the host. The index is lowercased up front, a subsequence check skips non-matches early, and highlights are computed only for visible rows. esbuild bundles the extension, and the Anthropic SDK loads only when you first use Claude. npm run bench on an Apple M2 Pro: | Items | Average rank | p95 | |---|---|---| | 1,000 | 0.3 ms | 0.5 ms | | 5,000 | 1.0 ms | 1.9 ms | | 20,000 | 4.2 ms | 7.7 ms | For extension authors, teams and pack publishers. The full guide is docs/BUILDING ACTIONS.md https://github.com/meness/slashi/blob/main/docs/BUILDING ACTIONS.md . - Publish a pack: add it to marketplace/packs https://github.com/meness/slashi/blob/main/marketplace/packs in a pull request, or host a private registry for your team and add it to slashi.marketplace.registries . - Add commands from your extension with registerCommand : js const slashi = await vscode.extensions.getExtension 'meness.slashi' ?.activate ; slashi?.registerCommand { extensionId: 'acme.deploy', name: 'deploy', title: 'Deploy to Staging', icon: 'rocket-launch', args: 'service', run: service = deploy service , } ; - Add a whole provider with registerProvider Slashi 0.5.0+ : your own results under your own scope, such as /jira listing your tickets. See Providers https://github.com/meness/slashi/blob/main/docs/BUILDING ACTIONS.md providers . Bug reports, ideas, action packs and pull requests are welcome.
