Think of it as a remote control for Chrome/Firefox/WebKit that works from the shell.\n\n**Concrete example** — scrape a page and get its content as Markdown:\n\n```bash\nspel open https://news.ycombinator.com\nspel markdownify                          # page content as clean Markdown\nspel screenshot front-page.png            # take a screenshot\nspel close\n```\n\n**Why not just use Puppeteer / Playwright directly?**\n\n- **No Node.js, no `node_modules`, no 100 MB binary downloads.** spel is a single self-contained binary (~71 MB). It uses Playwright Java under the hood, but you don't need to set up a Node project, manage npm dependencies, or deal with binary downloads on every `npm install`.\n- **Persistent browser session.** spel runs a background daemon — your browser stays open between commands. This makes it fast for interactive use and for AI agents that need to issue many commands in sequence.\n- **Works as a CLI, not just a library.** You don't need to write a script to automate a browser. Just type `spel open`, `spel click`, `spel fill` in your terminal (or let your AI agent do it).\n\n**Why not just use Claude Code's `--chrome` / browser MCP tools?**\n\nYou can! If Claude Code's built-in browser works for you, keep using it. spel offers more when you need:\n\n- **Persistent sessions** across multiple agent commands (the browser stays open)\n- **Accessibility snapshots** — a structured, numbered view of the page that's better than raw HTML for AI agents\n- **E2E test generation** — record a browser session and turn it into a test\n- **Allure reports** — detailed test reports with traces, screenshots, and network inspection\n- **CI integration** — run the same tests headlessly in CI with proper reporting\n- **Three browser engines** — Chromium, Firefox, and WebKit\n\n**Who is this for?**\n\n| You want to... | spel gives you... |\n|----------------|-------------------|\n| Automate a browser from the terminal | `spel open`, `spel click`, `spel fill`, `spel screenshot` |\n| Scrape page content | `spel markdownify`, `spel snapshot`, `spel get text` |\n| Write E2E tests | Clojure test framework with Allure reports, or record-and-generate |\n| Let an AI agent control a browser | CLI commands + accessibility snapshots that agents can reason about |\n| Run browser tests in CI | Headless mode + Allure reporting + video recording |\n\n## Rationale\n\nspel wraps Playwright Java with idiomatic Clojure: maps for options, anomaly maps for errors, `with-*` macros for lifecycle, and a native CLI binary for instant browser automation.\n\n- **Single binary, no ecosystem baggage**: One download, no `node_modules`, no npm, no transitive dependency surprises. Install the binary, install browsers, done.\n- **Persistent daemon**: First command auto-starts a background browser. Subsequent commands reuse it. No cold-start on every invocation — fast enough for interactive loops and AI agents.\n- **Accessibility snapshots**: Pages are represented as structured, numbered documents (not raw HTML). AI agents can read them like text and reference elements by number — no brittle CSS selectors.\n- **Record, then generate**: Capture any browser session to JSONL and auto-generate idiomatic Clojure tests or reusable scripts.\n- **Allure reports with network inspection**: Full Allure reporting with Playwright traces, network visualization (method, status, headers, body), and visual diffs.\n- **API testing built in**: Intercept, assert, and inspect HTTP traffic in the same tool as your browser tests.\n- **Three browser engines**: Chromium, Firefox, and WebKit — full Playwright API coverage.\n- **Inline Clojure scripting**: Run arbitrary Clojure expressions mid-session via `eval-sci` — not just shell commands, but real code.\n\n## Quick Start\n\n### Install\n\n**Clojure library:**\n\n```clojure\n;; deps.edn\n{:deps {com.blockether/spel {:mvn/version \"0.9.0\"}}}\n```\n\n**Native CLI (download from GitHub releases):**\n\n```bash\n# macOS (Apple Silicon)\ncurl -LO https://github.com/Blockether/spel/releases/latest/download/spel-macos-arm64\nchmod +x spel-macos-arm64 \u0026\u0026 mv spel-macos-arm64 ~/.local/bin/spel\n\n# Linux (amd64)\ncurl -LO https://github.com/Blockether/spel/releases/latest/download/spel-linux-amd64\nchmod +x spel-linux-amd64 \u0026\u0026 mv spel-linux-amd64 ~/.local/bin/spel\n\n# Linux (arm64)\ncurl -LO https://github.com/Blockether/spel/releases/latest/download/spel-linux-arm64\nchmod +x spel-linux-arm64 \u0026\u0026 mv spel-linux-arm64 ~/.local/bin/spel\n\n# Windows (PowerShell)\nInvoke-WebRequest -Uri https://github.com/Blockether/spel/releases/latest/download/spel-windows-amd64.exe -OutFile spel.exe\nMove-Item spel.exe \"$env:LOCALAPPDATA\\Microsoft\\WindowsApps\\spel.exe\"\n```\n\nAdd `~/.local/bin` to your PATH:\n\n```bash\nexport PATH=\"$HOME/.local/bin:$PATH\"  # add to ~/.bashrc or ~/.zshrc\n```\n\n**macOS Gatekeeper** (binaries are not Apple-signed):\n\n```bash\nxattr -d com.apple.quarantine ~/.local/bin/spel\n```\n\n**Post-install:**\n\n```bash\nspel install   # install browsers\nspel version   # verify installation\n```\n\n### Guided Installation (for LLM agents)\n\n\u003cdetails\u003e\n\u003csummary\u003eStep-by-step agent-driven install guide\u003c/summary\u003e\n\nIf you're an LLM agent installing spel for a user, follow these steps. Ask questions where indicated — adapt to the user's answers.\n\n#### Step 1: Detect platform and install binary\n\nDetect the user's OS and architecture, then download the correct binary:\n\n| Platform | Binary name |\n|----------|------------|\n| macOS Apple Silicon | `spel-macos-arm64` |\n| Linux x86_64 | `spel-linux-amd64` |\n| Linux ARM64 | `spel-linux-arm64` |\n| Windows x86_64 | `spel-windows-amd64.exe` |\n\n**Agent:**\n1. Run `uname -s` + `uname -m` (Unix) or check `$env:PROCESSOR_ARCHITECTURE` (Windows)\n2. Download from `https://github.com/Blockether/spel/releases/latest/download/\u003cbinary\u003e`\n3. Place in `~/.local/bin/` (Unix) or `%LOCALAPPDATA%\\spel\\` (Windows)\n4. Make executable: `chmod +x` (Unix only)\n5. On macOS: remove quarantine with `xattr -d com.apple.quarantine`\n6. Ensure the install directory is in PATH — detect shell and add to the correct config file\n\n#### Step 2: Ask — Which browser?\n\n\u003e \"Which browser do you primarily use? **Chrome**, **Edge**, or **Brave**?\"\n\nBased on the answer, set the default channel:\n\n| Answer | Channel |\n|--------|---------|\n| Chrome (default) | `chrome` (no flag needed) |\n| Edge | `msedge` |\n| Brave | `brave` |\n\nSet `SPEL_CHANNEL` environment variable to the chosen channel (e.g. `msedge`, `brave`). Skip for Chrome — it's the default.\n\n#### Step 3: Ask — Use your real browser profile?\n\n\u003e \"Do you want spel to use your real browser profile? This gives you all your extensions, saved passwords, bookmarks, and preferences inside spel.\"\n\nIf **yes**, detect the profile path:\n\n| OS | Chrome | Edge |\n|----|--------|------|\n| macOS | `~/Library/Application Support/Google/Chrome/Default` | `~/Library/Application Support/Microsoft Edge/Default` |\n| Linux | `~/.config/google-chrome/Default` | `~/.config/microsoft-edge/Default` |\n| Windows | `%LOCALAPPDATA%\\Google\\Chrome\\User Data\\Default` | `%LOCALAPPDATA%\\Microsoft\\Edge\\User Data\\Default` |\n\nVerify the profile exists, then set:\n\nSet `SPEL_PROFILE` environment variable to the detected path.\n\nIf **no**, skip — spel will use a fresh browser context each time.\n\n#### Step 4: Ask — Corporate proxy?\n\n\u003e \"Are you behind a corporate proxy (Zscaler, Netskope, etc.)? If unsure, try `spel install` first — if it fails with 'PKIX path building failed', you need this.\"\n\nIf **yes**:\n\nSet both `SPEL_CA_BUNDLE` and `NODE_EXTRA_CA_CERTS` environment variables to the path of the corporate CA bundle (PEM format). Ask the user where the cert file is, or help them find it.\n\nSee the [Corporate Proxy](#corporate-proxy--custom-ca-certificates) section below for details.\n\n#### Step 5: Install browsers\n\nRun `spel install` to download Chromium. If the user chose Edge, also run `spel install msedge`.\n\n#### Step 6: Ask — Automation or testing?\n\n\u003e \"Will you use spel for **automation only** (scripting, scraping, agents) or also for **writing tests** (with assertions and Allure reports)?\"\n\nScaffold agent skills (all 8 agents by default, use `--only` to scaffold a subset, or `--no-tests` to skip the seed test file):\n\n```bash\n# Full scaffolding with all 8 agents (default)\nspel init-agents\n\n# All agents, no seed test or specs directory\nspel init-agents --no-tests\n\n# Scaffold only specific groups\nspel init-agents --only=test          # test agents only\nspel init-agents --only=automation    # browser automation agents only\nspel init-agents --only=visual        # visual QA agents only\nspel init-agents --only=bugfind      # adversarial bug-finding agents only\nspel init-agents --only=orchestrator # orchestrator agent only\nspel init-agents --only=discovery    # product discovery agents only\n```\n\nChoose the right loop for your coding agent:\n\n```bash\nspel init-agents --loop=opencode   # OpenCode (default)\nspel init-agents --loop=claude     # Claude Code\n```\n\n#### Step 7: Verify\n\nRun `spel version` to confirm installation. Then test with `spel open https://example.com` — it should open and return JSON. Run `spel close` after.\n\nIf the user chose to use a profile, test with their profile path to verify it works.\n\n#### Step 8: Persist configuration\n\nSave the user's choices so they don't need to pass flags every time. Detect their shell and OS, then write to the correct config file:\n\n| OS | Shell | Config file |\n|----|-------|-------------|\n| macOS/Linux | zsh | `~/.zshrc` |\n| macOS/Linux | bash | `~/.bashrc` |\n| macOS/Linux | fish | `~/.config/fish/config.fish` (use `set -Ux VAR value`) |\n| Windows | PowerShell | `$PROFILE` (use `[Environment]::SetEnvironmentVariable(\"VAR\", \"value\", \"User\")`) |\n| Windows | cmd | `setx VAR value` |\n\n**Agent:** detect the shell (`echo $SHELL` on Unix, `$PSVersionTable` on Windows) and write the env vars to the correct file using the correct syntax.

The first command auto-starts a background browser daemon; subsequent commands reuse the same browser session.\n\n**Navigate and interact:**\n\n```bash\nspel open https://example.org             # open a page\nspel click \"text=More information\"        # click a link by text\nspel fill \"#search\" \"browser automation\"  # fill an input field\nspel press Enter                          # press a key\nspel screenshot result.png                # take a screenshot\nspel close                                # close the session\n```\n\n**Read page content:**\n\n```bash\nspel get title                            # page title\nspel get text                             # all visible text\nspel get html                             # full HTML\nspel markdownify                          # page as clean Markdown\nspel snapshot -i                          # accessibility snapshot with numbered refs\n```\n\n**Multiple sessions in parallel:**\n\n```bash\nspel --session shop open https://shop.example.com\nspel --session docs open https://docs.example.com\nspel --session shop screenshot shop.png\nspel --session docs screenshot docs.png\n```\n\n**Use your real Chrome profile** (with extensions, saved passwords, etc.):\n\n```bash\nexport SPEL_CHANNEL=chrome\nexport SPEL_PROFILE=\"$HOME/.config/google-chrome/Default\"\nspel open https://github.com    # opens with your logged-in session\n```\n\nRun `spel --help` for the full command list (~150 commands covering navigation, interaction, content extraction, network interception, cookies, tabs, frames, debugging, and more).\n\n### Clojure Library\n\nspel is also a Clojure library for writing browser automation and tests programmatically:\n\n```clojure\n(require '[com.blockether.spel.core :as core]\n         '[com.blockether.spel.page :as page])\n\n(core/with-testing-page [pg]\n  (page/navigate pg \"https://example.org\")\n  (page/title pg))\n;; =\u003e \"Example Domain\"\n```\n\nDevice emulation:\n\n```clojure\n(core/with-testing-page {:device :iphone-14 :locale \"fr-FR\"} [pg]\n  (page/navigate pg \"https://example.org\"))\n```\n\nCombined browser + API testing (shared Playwright trace):\n\n```clojure\n(core/with-testing-page [pg]\n  (page/navigate pg \"https://example.org/login\")\n  (core/api-get (core/page-api pg) \"/api/me\"))\n```\n\n### API Testing \u0026 Playwright-Style Tests\n\n**Write browser and API tests side-by-side:**\nspel lets you write browser tests (open pages, click buttons, verify DOM) and API tests (call endpoints, check responses) using the same framework. You get full Playwright traces for both.\n\n**API testing on its own:**\n\n```clojure\n(core/with-testing-api {:base-url \"https://api.example.org\"} [ctx]\n  (core/api-get ctx \"/users\"))\n```\n\n**Combine browser + API for a single trace:**\nYou can link UI and API actions within the same test, ensuring one trace covers front-end and back-end steps:\n\n```clojure\n(core/with-testing-page [pg]\n  (page/navigate pg \"https://example.org/login\")\n  (core/api-get (core/page-api pg) \"/api/me\"))\n\n(core/with-testing-page [pg]\n  (page/navigate pg \"https://example.org/login\")\n  (core/with-page-api pg {:base-url \"https://api.example.org\"} [ctx]\n    (core/api-get ctx \"/me\")))\n```\n\n**Retry/polling logic built in:**\nTo handle flaky endpoints or wait for backend jobs:\n\n```clojure\n(core/with-retry {}\n  (core/api-get ctx \"/flaky-endpoint\"))\n\n(core/with-retry {:max-attempts 10 :delay-ms 1000 :backoff :fixed\n                  :retry-when (core/retry-guard #(= \"ready\" (:status %)))}\n  (core/api-get ctx \"/job/123\"))\n```\n\n\u003e **Important:** Do not nest `with-testing-page` inside `with-testing-api` (or vice versa). Each creates its own Playwright instance, browser, and context, so you end up with separate traces. Use `page-api` or `with-page-api` when you want UI and API steps in one trace.\n\n**Allure reporting:**\nBrowser and API tests can feed the same Allure report with traces, screenshots, steps, and network inspection, so one run tells the whole story.\n\nSee the [full API reference](resources/com/blockether/spel/templates/skills/spel/references/FULL_API.md), [browser options](resources/com/blockether/spel/templates/skills/spel/references/BROWSER_OPTIONS.md), [Allure reporting](resources/com/blockether/spel/templates/skills/spel/references/ALLURE_REPORTING.md), and [API testing](resources/com/blockether/spel/templates/skills/spel/references/API_TESTING.md).\n\n## Ready-made Prompts for AI Coding Agents\n\n**What this does:** `spel init-agents` generates pre-written prompt files that teach your AI coding agent (Claude Code, OpenCode, etc.) how to use spel. After running this command, your agent knows all spel commands, best practices, and can write E2E tests, automate browsers, or find bugs — without you having to explain spel's API yourself.\n\n**Think of it like this:** instead of copy-pasting documentation into your AI agent's context, `init-agents` drops the right instruction files into your project so the agent picks them up automatically.\n\n```bash\n# Generate prompt files for Claude Code:\nspel init-agents --loop=claude\n\n# Generate prompt files for OpenCode (default):\nspel init-agents\n```\n\n**What gets created:**\n\n| What | Where | Purpose |\n|------|-------|---------|\n| Agent prompt files | `.claude/agents/` or `.opencode/agents/` | Teach the AI agent how to use spel's commands |\n| API reference | `.claude/skills/spel/` | Complete command reference the agent can look up |\n| Seed test file | `test-e2e/` | A starter test file for the agent to build on |\n| Workflow prompts | `.claude/prompts/` | Step-by-step workflows the agent can follow |\n\n**After setup, you can ask your AI agent things like:**\n\n- \"Test the login page\" — the agent opens the browser, navigates, interacts, and writes assertions\n- \"Find bugs on the checkout flow\" — the agent explores the UI systematically, looking for issues\n- \"Scrape product data from this page\" — the agent uses spel commands to extract content\n\n\u003cdetails\u003e\n\u003csummary\u003eFull init-agents options\u003c/summary\u003e\n\n```bash\nspel init-agents                              # all 8 prompt sets (default)\nspel init-agents --loop=claude                # Claude Code format\nspel init-agents --only=test                  # only test-writing prompts\nspel init-agents --only=automation            # only browser automation prompts\nspel init-agents --only=visual                # only visual QA prompts\nspel init-agents --only=bugfind              # only bug-finding prompts\nspel init-agents --only=orchestrator          # only the orchestrator prompt\nspel init-agents --only=test,visual           # combine groups\nspel init-agents --only=discovery             # only product discovery prompts\nspel init-agents --only=core                  # simplified 6-prompt core setup\nspel init-agents --simplified                 # same as --only=core\nspel init-agents --flavour=clojure-test       # clojure.test instead of Lazytest\nspel init-agents --no-tests                   # skip seed test and specs directory\n```\n\n| Flag | Default | Purpose |\n|------|---------|---------|\n| `--loop TARGET` | `opencode` | Which AI coding agent: `opencode` or `claude` |\n| `--only GROUPS` | — | Only generate specific prompt groups (comma-separated) |\n| `--simplified` | — | Simplified 6-prompt setup (alias for `--only=core`) |\n| `--ns NS` | dir name | Base namespace for generated tests |\n| `--flavour FLAVOUR` | `lazytest` | Test framework: `lazytest` or `clojure-test` |\n| `--no-tests` | — | Skip seed test scaffolding |\n| `--learnings` | — | Agents will maintain a `LEARNINGS.md` file where they record gotchas and patterns they discover while working (useful for building up project-specific knowledge over time) |\n| `--dry-run` | — | Preview what files would be created without writing them |\n| `--force` | — | Overwrite existing files |\n| `--test-dir DIR` | `test-e2e` | Where to put E2E test files |\n\n\u003c/details\u003e\n\n\u003cdetails\u003e\n\u003csummary\u003eAvailable prompt groups\u003c/summary\u003e\n\n| Group | What the agent can do | Included prompts |\n|-------|----------------------|------------------|\n| `test` | Plan and write E2E tests | test-planner, test-writer |\n| `automation` | Explore UIs and automate browser flows | explorer, automator |\n| `visual` | Generate visual content and slides | presenter |\n| `bugfind` | Systematically find bugs and visual regressions | bug-hunter |\n| `orchestrator` | Smart routing — analyzes your request and picks the right workflow | orchestrator |\n| `discovery` | Inventory product features and audit UX coherence | product-analyst |\n\nThe **orchestrator** is a good default entry point — tell it what you want and it delegates to the right specialist.
