Lore Agent Harness Plugins

This repo contains skills for sharing and working with Lore threads. The skills are distributed as plugins for Claude Code, Cowork, Codex, and Amp. See how to share Claude Code sessions with your team.

See the docs for more details.

Install

Claude Code

From a plain terminal (outside a session), run the following commands:

claude plugin marketplace add loredotlink/lore-plugin
claude plugin install plugin@loredotlink

Codex

From a plain terminal (outside a session), run:

codex plugin marketplace add loredotlink/lore-plugin
codex plugin add lore@loredotlink

Start a new Codex session after installation. Type @share and select the Lore share skill to insert $lore:share, or ask Codex to share the session to Lore in natural language.

Amp

Amp does not use the Claude/Codex manifests. Amp loads TypeScript plugins from local files:

• Project plugin: .amp/plugins/*.ts
• System plugin: ~/.config/amp/plugins/*.ts

Use the script below to clone this repo and copy the standalone Amp plugin into a location that Amp will recognize:

if [ -d ~/.local/share/lore-plugin/.git ]; then
  git -C ~/.local/share/lore-plugin pull --ff-only
else
  git clone https://github.com/loredotlink/lore-plugin ~/.local/share/lore-plugin
fi

mkdir -p ~/.config/amp/plugins
rm -f ~/.config/amp/plugins/lore.ts
cp ~/.local/share/lore-plugin/amp/lore-bundled.js ~/.config/amp/plugins/lore.ts

amp plugins list

Then reload plugins from Amp's command palette with plugins: reload. The command palette should show Lore: Share active Amp thread. amp plugins list should include:

✓ /Users/.../.config/amp/plugins/lore.ts active
  Command: Lore: Share active Amp thread
  Tool: share_current_amp_thread
  Tool: lore_login
  Tool: lore_login_resume
  Tool: get_thread
  Tool: list_threads
  Tool: search_threads
  Tool: fork_thread

What you get

• Share skill — /lore:share in Claude Code/Cowork or $lore:share in Codex uploads the current session to Lore and returns a shareable URL.
• Fork skill — /lore:fork in Claude Code/Cowork distills an existing Lore thread into intent-conditioned handoff context for continuing work; Codex exposes the same installed skill through its @ picker.
• Read skill/tools — /lore:read in Claude Code/Cowork fetches a Lore thread by ID or URL, or lists and searches threads by title; Codex exposes the same installed skill through its @ picker.
• Lore: Share active Amp thread — in Amp, export the active Amp thread with the local Amp CLI, upload the raw export to Lore as harness: 'amp', and return the Lore URL for that session.
• share_current_amp_thread — an Amp tool for explicit natural-language invocation. It accepts { thread_id?: string, visibility?: 'private' | 'workspace' | 'public', highlight?: string }; if thread_id is omitted, AMP_CURRENT_THREAD_ID must be set or the tool returns an actionable error. highlight is a natural-language description of the block or block range to emphasize in the returned Lore URL.

In Claude Code, Cowork, and Codex, you can also share to Lore using natural language (e.g. "share this session to Lore").

The plugin shares sessions only when you explicitly use /share or its manual sharing tools.

When you share a thread, you can also specify specific blocks that should be highlighted (e.g. "share the final outcome of this investigation"). Lore resolves the description against parsed thread blocks and returns a thread_url with corresponding anchor tags when it finds a confident match. If highlight resolution fails or times out, sharing still succeeds and returns the base thread URL without anchor tags.

First-time setup

The first time you use a Lore share/read skill or the Amp share/read tools, the plugin's lore_login tool opens a browser to kick off a login flow. The plugin persists an auth and refresh token in the ~/.lore/tokens.json file (mode 0600). If the browser cannot be opened automatically (SSH or other environments without a GUI), lore_login returns a verification_uri + device_code and the agent calls lore_login_resume once you complete the flow on another device.

Architecture

The shared package contains host-specific manifests for Claude Code and Codex, an Amp TypeScript plugin entrypoint, one bundled stdio MCP server that reads Claude/Cowork/Codex local session bytes off disk, and the proxy/auth code that talks to the Lore cloud MCP at https://mcp.lore.link/mcp. The stdio binary is a Bun-compiled single executable. Auth runs in-process via the lib/auth/ library, with shared token storage, legacy migration, OAuth discovery, and refresh logic delegated to @lore/identity-store: RFC 8628 device-code flow against WorkOS AuthKit, discovery-driven (PRM → AS metadata, cached at ~/.lore/discovery-cache.json), with silent refresh and 401-triggered re-login. See DESIGN.md for the full breakdown.

Capture ownership is deliberately outside this package: Desktop owns configuration and capture. The plugin owns authentication, local reads, explicit sharing, and cloud consumption only.

This repo is a mirrored subtree from our internal monorepo.

Requirements and limitations

• macOS arm64 only for the packaged stdio MCP binary in v1. The plugin ships a precompiled Bun binary for Apple Silicon — Intel Macs and Linux are out of scope for now.
• Amp sharing requires the local amp CLI to be installed and able to run amp threads export <thread_id>.
• Amp installation is local file-based for now. Do not assume an Amp marketplace distribution exists.
• Amp active-thread sharing is command-palette based. Natural-language sharing is available through the explicit share_current_amp_thread tool when a thread ID is supplied or AMP_CURRENT_THREAD_ID is present; automatic agent-context injection may come later.
