Local command room for AI coding agents, session recall, and project handoffs.

Quick Start · Features · Connecting Hermes · MCP Bridge · Testing

Athena is a local desktop workspace for orchestrating AI coding agents with shared project context. It gives developers one Electron app for launching Codex, OpenCode, Claude Code, Athena Code, Hermes, and shell sessions; inspecting live terminal output and native session history; generating project handoffs; and keeping short-lived recall context available to the next agent.

In search terms: Athena is an AI coding agent workspace, multi-agent desktop app, embedded terminal control room, Hermes MCP bridge, and session recall manager for local software development.

LLM Summary

Athena is an Electron + React desktop application with a FastAPI backend for managing local AI coding agent sessions. It supports embedded PTY terminals through node-pty and xterm.js, native session discovery for Codex, OpenCode, Claude Code, Athena Code, and Hermes, project-local recall caches, session handoff generation, recall audit metadata, and an MCP server that lets Hermes control the running desktop workspace.

What Athena Solves

AI coding tools often run as isolated terminals, each with its own context window and history. Athena turns those separate agent sessions into one local command room:

• Start shell, Hermes, Codex, OpenCode, Claude, and Athena Code sessions from one UI.
• Resume native agent sessions already stored on disk.
• Inspect live terminal buffers, native transcripts, and provider metadata.
• Generate bounded handoffs from useful session evidence.
• Save handoffs into project-local recall for the next fresh agent.
• Let Hermes use MCP tools to inspect sessions, write recall, and spawn visible Athena terminals.

Athena is not only a terminal emulator, memory store, or MCP server. It is a local orchestration surface for repeated, session-first AI development work.

Requirements

• Node.js and npm
• Python 3.11+ recommended
• pip
• Optional agent CLIs:
  • codex
  • opencode
  • claude
  • athena-code
  • hermes
• Optional Hermes Agent install for real shared memory integration

The desktop app can open without every agent CLI installed. Missing adapters appear as unavailable, and related launch commands may fail inside the terminal until the CLI is installed and available on PATH.

Quick Start

git clone https://github.com/luckeyfaraday/Athena.git
cd Athena/client
npm install
npm run dev

For the full backend/test environment, use the setup steps below.

Setup

Install the client dependencies:

Install backend dependencies from the repository root:

python3 -m venv .venv
source .venv/bin/activate
pip install -r backend/requirements.txt

For tests, install pytest if it is not already available:

If your preferred Python is not python3, set:

export CONTEXT_WORKSPACE_PYTHON=/absolute/path/to/python

The Electron app uses this value when spawning the FastAPI backend.

Running The Desktop App

How Agent Sessions Work

Athena's primary workflow is embedded, interactive agent sessions. The Electron main process launches terminal panes for shell, Hermes, Codex, OpenCode, Claude, and Athena Code. The React UI renders those panes with xterm.js.

By default, fresh agent panes start without Athena project context. Athena only creates and attaches memory, recall, and project-instruction bundles when an explicit immersive context mode is selected. It then:

1. Creates an immutable workspace-scoped context bundle.
2. Writes a compact bootstrap prompt that points at the bundle.
3. Starts the selected CLI in an embedded PTY.
4. Tracks the pane as a live session and captures a bounded terminal buffer for review.

Athena also discovers native provider sessions already on disk, so previous Codex, OpenCode, Claude Code, Athena Code, and Hermes work can be inspected or resumed from the Sessions tab.

Session Handoffs

Athena Session Handoffs are bounded markdown summaries generated from selected sessions in Review Room. They are designed to help a new agent start fresh without losing useful project context.

The handoff flow:

1. Select one or more useful live or native sessions.
2. Athena extracts usable evidence and filters terminal UI noise.
3. Review the generated handoff preview.
4. Save the handoff to project-local recall.
5. Start a fresh Codex, OpenCode, Claude, or Athena Code session with that recall attached.

Handoffs do not blindly merge full transcripts. Metadata-only sessions and terminal buffers with no usable task evidence are rejected or clearly marked.

Legacy Backend Runs

The backend still includes an older one-shot run registry and Codex adapter. This path receives an agent spawn request, creates a run record, writes bounded artifacts under .context-workspace/runs/<run-id>/, executes the CLI process, and exposes status/artifact endpoints.

That backend-run flow is maintained for compatibility and tests. Athena's current product direction is session-first embedded terminals plus native session discovery. Generated context artifacts are cache/output files. Hermes memory and project-local recall remain the durable shared context.

Embedded Terminals

The Electron main process manages embedded terminals through node-pty. The React UI renders them with xterm.js.

The New menu can launch:

• Shell
• Hermes
• Athena Code
• Athena Code Grid
• Codex
• Codex Grid
• OpenCode
• OpenCode Grid
• Claude
• Claude Grid

Agent panes receive a generated Athena prompt path only for task, curated, or explicit immersive launches. Clean launches receive no prompt path.

Hermes Memory

The backend uses HermesManager and HermesMemoryStore to find Hermes status and read/write memory.

Memory query endpoint:

GET /memory/hermes?q=<query>

The response is plain text so CLI agents can consume it easily with tools like curl.

Agent Skills

On every launch, the Athena desktop app installs a bundled agent skill named athena-context-workspace into the local skill directories of the supported coding agents:

~/.codex/skills/athena-context-workspace
~/.claude/skills/athena-context-workspace
~/.config/opencode/skills/athena-context-workspace

The skill source lives in agent-skills/athena-context-workspace/ and is copied by installManagedAgentSkills() (client/electron/agent-skills.ts). Athena tracks what it installed in ~/.context-workspace/agent-skills.json, so updates are applied cleanly and directories with your own edits are never overwritten.

This skill teaches Codex, Claude Code, and OpenCode how to behave inside an Athena workspace, including how to route ask hermes requests. There is no separate ask-hermes skill to install — the Hermes routing rules live inside athena-context-workspace.

Asking Hermes

When the user says ask hermes ..., the agent routes the question through Athena instead of shelling out to the hermes binary directly:

1. If the Athena MCP tools are loaded, it calls context_workspace_ask_hermes(workspace, question).
2. Otherwise, if CONTEXT_WORKSPACE_BACKEND_URL is set, it POSTs to /hermes/ask with { project_dir, question }.

Both paths reach the local Athena backend, which runs Hermes once with the project as context and returns the answer. Routing through the backend keeps logging, project scoping, and recall consistent across agents.

Connecting Hermes

"Connecting Hermes" is two independent steps. The Settings → Hermes card in the desktop app shows the current state of both and provides actions where it can.

1. Install the Hermes Agent CLI. When the in-app installer is supported (Linux and macOS with bash and curl), the Hermes card shows an Install Hermes button wired to POST /hermes/install. On native Windows, install the native Hermes build separately and make sure hermes is on your PATH. Athena detects Hermes through shutil.which("hermes") plus ~/.hermes.

2. Point Hermes at the Athena MCP bridge. So Hermes can call Athena's context_workspace_* tools, add the bridge block to your Hermes config (~/.hermes/config.yaml). The Hermes card has a Connect Hermes to Athena helper with a copyable snippet; the full setup (paths, tokens) is in Hermes MCP Bridge below.

The coding-agent skills above and the Hermes bridge are complementary: the skills let Codex/Claude/OpenCode ask Hermes through Athena, while the bridge lets Hermes drive Athena (spawn terminals, read sessions, write recall).

Hermes MCP Bridge

Athena includes an MCP server under mcp_server/ so Hermes can call into the running desktop workspace.

Install the MCP server dependencies into the Python environment Hermes will use:

pip install -r ~/context-workspace/mcp_server/requirements.txt

Add the bridge to the Hermes config at ~/.hermes/config.yaml:

mcp_servers:
  context_workspace:
    command: "python"
    args:
      - "/home/you/context-workspace/mcp_server/server.py"
    timeout: 120
    connect_timeout: 30
    env:
      CONTEXT_WORKSPACE_BACKEND_STATE: "/home/you/.context-workspace/backend.json"

If Hermes uses its own virtual environment, set command to that interpreter:

command: "/home/you/.hermes/hermes-agent/venv/bin/python3"

The Electron app writes backend discovery state to:

~/.context-workspace/backend.json

(On Windows: C:\Users\you\.context-workspace\backend.json.)

Start the Athena desktop app before starting Hermes so the backend state file exists. If you run the backend directly on a fixed port, you can use CONTEXT_WORKSPACE_BACKEND_URL instead:

env:
  CONTEXT_WORKSPACE_BACKEND_URL: "http://127.0.0.1:8000"

The bridge exposes tools for health checks, Hermes memory reads/writes through the backend, native agent session discovery, visible embedded terminal spawning, legacy agent run management, artifact reads, transcript reads, and project-local recall cache management.

Visible terminal tools require the Electron app itself, not only the FastAPI backend. Electron writes control discovery state to:

~/.context-workspace/electron-control.json

(On Windows: C:\Users\you\.context-workspace\electron-control.json.)

Set CONTEXT_WORKSPACE_ELECTRON_CONTROL_URL only when you need to override this discovery file.

The Electron control server requires a per-launch secret token for every endpoint except /health. The desktop app generates the token at startup and writes it into electron-control.json (created with 0600 permissions). The MCP bridge reads the token from that discovery file automatically and sends it as a Bearer token, so no manual configuration is needed in the normal flow. When you override discovery with CONTEXT_WORKSPACE_ELECTRON_CONTROL_URL, also set CONTEXT_WORKSPACE_ELECTRON_CONTROL_TOKEN to the token from that file. The token, loopback-only Host enforcement, and rejection of cross-origin requests together prevent other local processes and malicious web pages from driving the control server (process spawning, terminal input injection, buffer reads).

When Electron starts the backend, it configures a default recall refresh command:

python scripts/hermes-refresh-recall.py

You can override it with CONTEXT_WORKSPACE_HERMES_REFRESH_CMD. The default script writes a short project-local recall cache and uses native Codex/OpenCode/Claude/Athena Code session discovery as fallback context, which keeps recall refresh working even when Hermes cannot reach the backend loopback URL.

If the same projects live under different usernames on different machines (for example C:\Users\alanq\... on Windows and /home/alan/... on Linux), set CONTEXT_WORKSPACE_HOME_ALIASES to the extra usernames (comma-separated, e.g. alan,alanq) so project-scoped memory matching recognizes both home paths.

Recommended recall workflow:

1. Hermes runs its own session_search.
2. Hermes calls context_workspace_summarize_agent_sessions when it needs native Codex/OpenCode/Athena Code/Claude session history for the selected workspace.
3. Hermes summarizes the relevant prior-session context.
4. Hermes calls context_workspace_write_recall_cache(project_dir, markdown).
5. Future Athena agent launches include that cache in the generated prompt context.

Useful MCP tools for this workflow:

context_workspace_list_agent_sessions(project_dir, provider?, query?, limit?)
context_workspace_summarize_agent_sessions(project_dir, provider?, query?, limit?)
context_workspace_open_workspace(project_dir, select?)
context_workspace_spawn_agent(project_dir, task, agent_type?, visible_terminal?, open_workspace?)
context_workspace_spawn_terminal(project_dir, kind?, count?, title?, resume_session_id?, session_label?, open_workspace?)
context_workspace_kill_terminal(target)
context_workspace_close_workspace(project_dir)
context_workspace_read_agent_session(provider, session_id, max_bytes?, tail?)
context_workspace_write_recall_cache(project_dir, markdown)
context_workspace_read_recall_cache(project_dir)
context_workspace_clear_recall_cache(project_dir)

Use context_workspace_spawn_agent for user-requested Codex, OpenCode, Athena Code, or Claude work. Pass agent_type="athena-code" or agent_type="athena" for Athena Code. It opens a visible Command Room PTY by default through Electron control, so Athena must be running. Set open_workspace=true when Hermes should add/select a project folder in Athena before spawning. Use context_workspace_spawn_terminal for lower-level terminal control such as shells, grids, Hermes panes, or explicit resumes; its kind accepts athena-code as an alias for the live athena terminal kind.

Use context_workspace_kill_terminal to stop one live Athena PTY by terminal id or provider session id. Use context_workspace_close_workspace to close a workspace tab and stop its live embedded terminals.

Do not use the FastAPI backend POST /agents/spawn route for OpenCode or Claude visible terminals. That backend route is the legacy run/artifact path. If visible spawning fails with an Electron control error, check ~/.context-workspace/electron-control.json and restart the Athena desktop app.

Athena owns these app-side tools. Hermes still owns its own config, session_search, long-term memory writes, and the decision about when to refresh or clear recall.

Use Cases

• Run several AI coding agents against one local project.
• Resume prior Codex, OpenCode, Claude Code, Athena Code, or Hermes work.
• Review what an agent did before deciding what context to keep.
• Start a new agent with a curated handoff instead of a full noisy transcript.
• Let Hermes control visible Athena terminals through MCP.
• Keep project-local recall separate across workspaces.

Athena Code

Athena Code is a standalone opencode fork that lives in its own repository and installs its own athena-code CLI. Athena treats it exactly like Codex, OpenCode, and Claude Code: the Command Room launches it from the New menu as a regular embedded PTY, it must be on PATH, and it participates in the same clean/task/curated/immersive context modes as every other agent.

Every agent launch starts Clean unless an explicit context mode is selected. Immersive launches create a fresh immutable project-scoped context bundle and hand the agent a bootstrap prompt that points at the bundle file.

Troubleshooting

Backend does not start

Check that backend dependencies are installed and that Electron is using the expected Python:

export CONTEXT_WORKSPACE_PYTHON=/path/to/python

Then restart the desktop app.

Agent command is unavailable

Install the relevant CLI and make sure it is on PATH for the Electron process:

which codex
which opencode
which claude
which athena-code
which hermes

Multiple Athena windows show stale UI

Quit all running Athena/AppImage instances before testing a newly built AppImage. Linux AppImages mount into /tmp/.mount_ATHENA..., so an older running instance can make it look like a rebuild did not change the UI.

Embedded shell prints an nvm warning

If the app is launched through npm run dev, the embedded shell may inherit npm environment variables. With nvm, this can produce:

nvm is not compatible with the "npm_config_prefix" environment variable

This comes from shell startup, not the terminal renderer. A narrow fix is to sanitize npm_config_prefix from the PTY environment before spawning embedded terminals.

Port conflicts

Electron asks the OS for a free backend port. Vite uses 127.0.0.1:5173 during development.

Notes For Contributors

• Keep generated run artifacts inside .context-workspace/runs/<run-id>/.
• Do not overwrite user-owned AGENTS.md, CLAUDE.md, or tool configuration files without explicit opt-in.
• Keep Hermes memory as the durable source of shared context.
• Prefer adapter-specific behavior over assuming every agent CLI handles instructions the same way.
• Run pytest and npm run build before opening a PR.
