Tools

80x publishes the tools it builds for its own work: a free skill auditor, a commercial Mac app, and four open-source projects for teams running Attio or Affinity.

Free web app

Sentry

Reviews Claude Agent Skills for security and effectiveness: a deterministic scanner flags risky patterns in skill files, and an optional AI deep review writes a scored report. Built for the studio's own work and hardened by auditing itself.

Mac app, from $9/mo

Backchannel

A native Mac client that captures WhatsApp and LinkedIn conversations into Attio or Affinity. Official web clients under the hood, no unofficial API. Private by default, with a sync gate enforced on the server.

valentine

A read-only pre-call CRM agent: give it a domain or a name and it searches Attio or Affinity, then returns one verdict (prior_contact, clean, or ambiguous) with citations and exit codes. Ships a CLI and an MCP server, on npm as valentine-agent.

attio-cli

A command-line interface for Attio built agent-first: output modes chosen per call, help loaded on demand instead of resident schemas, and idempotent upsert and assert commands. Includes a published benchmark comparing CLI and MCP access.
