Engineering, finance, design, ops — Extender ships a growing library of role presets and lets your team customize each one to match how you actually work. A desktop runtime on every laptop, a control plane your platform team can trust.
Engineering is our flagship today. The library expands with every design partner.
The full feedback loop: scope → code → test → review → ship.
Per-team coding standards, framework focus, commit-message conventions, language style guides.
Stop telling people “just configure it locally.” Author the rules once; ship them everywhere.
Compose skills, hooks, MCP servers, and prompt overrides into reusable harnesses. Build once for the team, ship to every laptop, update centrally — no per-machine drift, no copy-paste configuration.
Security publishes a `pii-redaction` harness. Every workspace inherits it on the next session.
Start from a growing library of role presets — engineering, qa, finance, design, support, and many more — or compose your own. Each preset is a starting point your platform team customizes bespoke. Permission changes invalidate sessions instantly.
Finance uses the `month-end-close` preset with a NetSuite MCP and a SOX guardrail; design uses `brand-review` with read-only access to the design system.
Hooks fire before, during, or after every tool call — block destructive commands, gate approvals, redact PII, enforce working hours. Templates ship ready; add your own in TypeScript or bash. Enforced on the desktop, audited in the cloud.
Block any external API call that contains an email or SSN. Demand human approval before the agent sends a customer-facing message.
Pick a preset — security-focused, onboarding-friendly, executive-summary — or describe the change in your own words. Extender generates three variants, you pick one, and it rolls out to the team as a saved preset.
Finance lead retunes the `report-summary` skill for plain-English exec briefings. Saved as a tenant preset, applied across every analyst workspace.
Ships with Claude. v1.x adds OpenAI Codex and any Anthropic-compatible provider — switch per workspace, per skill, per cost target. Skills, hooks, and roles stay provider-agnostic, so your harness travels with you.
Research team on Claude for long-context work, ops team on a cheaper model for routine summaries — same audit, same governance.
Chats and files stay on your laptop. The control plane governs roles, harnesses, and audit — and never sees a prompt unless you opt in. Bring your own API key; no SaaS lock-in on the hot path.
A legal team runs locally on encrypted laptops; the cloud only stores who-changed-what for compliance, never the conversations.
Start from a role preset. Pick skills, wire MCP servers, attach hooks, override prompts. Save it as a workspace template.
Each person gets the right toolset for their workspace. Permission changes propagate instantly.
The Extender desktop app picks up the harness on next launch. Chats stay local; audit stays in the cloud.
We're onboarding design partners across every department. If your team uses AI assistants at any meaningful scale, we'd like to talk.
