OrchestKit security wrapper for browser automation. Adds URL blocklisting, rate limiting, robots.txt enforcement, and ethical scraping guardrails on top of the upstream agent-browser skill. Use when automating browser workflows that need safety guardrails.
Nightly memory consolidation — prunes stale entries, merges duplicates, resolves contradictions, rebuilds MEMORY.md index. Use when memory files have accumulated over many sessions and need cleanup. Do NOT use for storing new decisions (use remember) or searching memory (use memory).
Interactive configuration wizard for OrchestKit plugin settings including MCP server enablement, hook permissions, keybindings, and installation presets (Complete/Standard/Lite). Supports preset shortcuts, per-category skill customization, and webhook configuration. Use when customizing plugin behavior or managing settings.
OrchestKit doctor for health diagnostics across manifest integrity, hook configuration, skill validation, agent frontmatter, MCP server connectivity, CC version compatibility, and permission rules. Reports issues with severity levels and auto-remediation suggestions. Validates component counts, detects orphaned entries, and checks CC version matrix compliance. Use when diagnosing plugin health, troubleshooting configuration issues, or running pre-release checks.
Generate emulate seed configs for stateful API emulation. Wraps Vercel's emulate tool for GitHub, Vercel, Google OAuth, Slack, Apple Auth, Microsoft Entra, AWS (S3/SQS/IAM), Okta, Clerk, Resend, Stripe, and MongoDB Atlas APIs. Not mocks — full state machines where create-a-PR-and-it-appears-in-the-list, send-an-email-and-retrieve-from-local-inbox. Use when setting up test environments, CI pipelines, integration tests, or offline development.
Right-sizes architecture to project scope. Prevents over-engineering by classifying projects into 6 tiers and constraining pattern choices accordingly. Use when designing architecture, selecting patterns, or when brainstorm/implement detect a project tier.
Vision, audio, video generation, and multimodal LLM integration patterns. Use when processing images, transcribing audio, generating speech, generating AI video (Kling v3, Sora 2, Veo 3.1 std/lite/fast, Runway Gen-4.5 via `gen4_turbo`), or building multimodal AI pipelines.

OrchestKit security wrapper for agent-browser. For command reference and usage patterns, use the upstream agent-browser skill directly. This skill adds safety guardrails only.
Command docs: Refer to the upstream
agent-browserskill for the full command reference (50+ commands: interaction, wait, capture, extraction, storage, semantic locators, tabs, debug, mobile, network, cookies, state, vault).
# Fallback decision tree for web content
# 1. Try WebFetch first (fast, no browser overhead)
# 2. If empty/partial -> Try Tavily extract/crawl
# 3. If SPA or interactive -> use agent-browser
# 4. If login required -> authentication flow + state save
# 5. If dynamic -> wait @element or wait --text
Use Portless (npm i -g portless) for stable local dev URLs instead of guessing ports. When Portless is running, navigate to myapp.localhost:1355 instead of localhost:3000. Our safety hook already allows *.localhost subdomains via ORCHESTKIT_AGENT_BROWSER_ALLOW_LOCALHOST.
# With Portless: stable, named URLs
agent-browser open "http://myapp.localhost:1355"
# Without: fragile port guessing
agent-browser open "http://localhost:3000" # which app is this?
React introspection + perf observability (0.27):
react tree / react inspect <fiberId> / react renders start|stop / react suspense — first-class React DevTools integration via a vendored MIT-licensed hook embedded in the binary (zero runtime deps). Component-tree visibility, per-fiber props/hooks/state inspection, render profiling with mount/re-render counts and change details, Suspense boundary classification with root-cause grouping. Hook treats fiber state dumps as sensitive — gitignore captures.vitals [url] — reports Core Web Vitals (LCP, CLS, TTFB, FCP, INP) plus React hydration phases for any page. Useful for perf gates in CI.pushstate <url> — client-side SPA navigation without a full page load. Pairs with react renders to measure SPA route transitions without resetting profiling state.--init-script <path> (repeatable, env AGENT_BROWSER_INIT_SCRIPTS) + --enable <feature> (repeatable, env AGENT_BROWSER_ENABLE) — register scripts before first navigation; --enable react-devtools is built-in. Hook treats arbitrary init scripts as code-execution surface — same trust model as skills get.network route --resource-type <csv> — filter intercepted requests by CDP resource type (document, script, xhr, fetch, image, ...). Lets you mock only API calls without breaking page assets.cookies set --curl <file> — auto-detects JSON, cURL, and Cookie-header formats for bulk cookie import. Hook still treats cookie-set as auth-state injection.doctor generating duplicate check IDs when invoked multiple times in the same process.Diagnostic tooling + stable IDs (0.26):
agent-browser doctor — one-shot environment + Chrome + daemon + config + security + provider + network check. Flags: --offline, --quick, --fix, --json. Run before opening an issue to attach a structured snapshot.t1, t2, ...) with optional memorable labels via --label. Survives daemon restart; replaces brittle index-based references.core skill expanded — comprehensive built-in usage guide covering snapshot-ref-act loops, reading, interaction, waiting, and troubleshooting.$schema reference enables IDE auto-completion and validation against https://agent-browser.dev/schema.json.--state flag not loading saved cookies/localStorage at launch; --help now leads with the skills section.Skill discovery & chat (0.25):
agent-browser skills list/get <name> — discover and install capability packs on-demand. Hook treats first-party skills as trusted; warns on arbitrary third-party skill fetches.agent-browser chat — single-shot or REPL natural-language driving over the same daemon. Hook pipes transcripts through the same URL/rate/robots checks as scripted commands.Accessibility-first locators (0.24):
find / getByRole — semantic locator via CDP accessibility tree (role + name) instead of brittle CSS/ref selectors. Prefer these in new scripts; they survive markup churn and are the locator path assumed by chat.snapshot --urls — emits resolved URLs alongside refs, removing a round-trip for link-extraction flows.--annotate — overlays ref IDs / role labels on screenshots for debugging.Cloud providers (0.25):
--provider agentcore — AWS Bedrock AgentCore cloud browser. Hook treats remote providers as egress surfaces — same URL/robots rules apply, but network routing is disabled (remote scope).AGENT_BROWSER_PROVIDER env var.Dashboard (0.25):
agent-browser dashboard or the inspect CDP link. Still flagged as local-proxy attack surface by the hook.Auto-dialog dismissal (0.23.1):
--no-auto-dialog when a test needs to assert dialog content.Breaking changes — update scripts now:
--full / -f moved from global to command-level (v0.21): use screenshot --full, NOT --full screenshot--no-auto-dialogNew commands:
