DistributionCLI 0.1.0

A public CLI and inspectable discovery surface

Handover became installable from npm and discoverable through the official MCP Registry, mcpub, Glama, search engines, and agent-readable indexes.

  • Published the dependency-free handover-sh CLI with repository provenance and clean install verification.
  • Added the open AI Handoff Continuity Benchmark, reusable templates, working examples, and source-linked field guides.
  • Published llms.txt, llms-full.txt, ai-index.json, host recipes, and an MCP discovery manifest.
  • Automated IndexNow notifications and a weekly audit of every public canonical, social preview, crawler rule, and agent index.
What this means for agents

Agents can install a public CLI, inspect the hosted MCP contract, retrieve reusable knowledge assets, and verify Handover's current public capabilities without relying on marketing copy.

Collaboration

Revision-anchored review for humans and agents

People and agents can comment on the exact text, code, or file revision they reviewed, mention another authorized collaborator, and carry unresolved feedback into the next continuation.

  • Added anchored annotations for Markdown, code, JSON, and rendered artifact review.
  • Made annotation threads available in the workspace, full-screen reader, mobile drawer, HTTP API, and MCP.
  • Added edit, reply, resolve, reopen, and mention workflows without changing immutable revision contents.
  • Kept mentions access-neutral: a notification never grants permission to the underlying handover.
What this means for agents

Authorized agents can read unresolved review threads, add or edit feedback, mention a person or service identity, and resolve a thread after publishing the revision that addresses it.

Migration

Resumable Reporter migration and clearer revision history

Reporter inventories can move into Handover through bounded, resumable batches while preserving folders, publication bundles, file relationships, and the review queue.

  • Added resumable inventory, bounded retries, batch mappings, and recovery for interrupted Reporter imports.
  • Preserved Reporter-compatible publishing folders as projections over canonical Handover revisions.
  • Improved revision timelines with attributable human and agent activity.
  • Added readable formatting for SQL, scripts, Markdown source, and rendered previews.
What this means for agents

Agents can continue imported work through the same canonical MCP tools instead of targeting a separate legacy report store.

Onboarding

Private personal workspaces for individual developers

A person can use Handover without first creating a company, then move into shared company workflows when collaboration requires it.

  • Added private personal organizations isolated from every company workspace.
  • Added clear onboarding paths for individuals, company owners, employees, and service agents.
  • Added a full-page artifact reader and sign-in return paths for shared private links.
  • Published the CLI installer and external-user privacy and terms pages.
What this means for agents

An individual can issue a named agent credential inside a private workspace and preserve identity across model switches without exposing context to a company.

Identity

Company SSO, Spaces, and attributable agent access

Company members can join through an approved Google Workspace domain, organize context into Spaces, and give each human or agent an attributable identity.

  • Added Google SSO through Cloudflare Access and per-user OAuth attribution for supported MCP clients.
  • Added company naming, approved domains, invitations, membership roles, and a company view.
  • Added Spaces as logical product, department, or operating-area boundaries inside a company.
  • Added signed-in account details, logout, workspace selection, and automatic refresh.
What this means for agents

Agents authenticate as named service identities or supported human OAuth identities; authorship is derived from the credential rather than supplied in tool arguments.

Foundation

The first versioned handover platform

Handover launched on company-owned Cloudflare infrastructure with canonical D1 and R2 storage, MCP and HTTP interfaces, arbitrary artifacts, Spaces, and Reporter-compatible workflows.

  • Added immutable handover revisions, artifact storage, search, continuation briefs, comments, and lifecycle controls.
  • Added tenant isolation, scoped service credentials, backup verification, storage cells, and request tracing.
  • Added Markdown, SQL, HTML, JSON, image, and arbitrary-file publishing.
  • Added provider-neutral imports, exports, OKF interoperability, and production-safe MCP access.
What this means for agents

Agents gained one authenticated interface for finding, reading, publishing, and continuing durable context alongside human collaborators.
