C1 Identity & least privilege
Minimal 0.00 / 1.00
Archon acts with whatever authority the person running it has. The Claude Code subprocess, bash and script nodes all receive the full environment of the Archon process, so every API key, GitHub token and cloud credential in it is available to the agent, and the agent runs Claude Code with permission prompts switched off. A per-user GitHub token policy exists for multi-user server installs, but it does nothing in the default single-user CLI setup. If the agent is steered wrong, it can do anything the user's own accounts allow.
C2 Approval gates
Minimal 0.05 / 1.00
Archon deliberately runs Claude Code in its permission-bypass mode and Codex with approvals set to never, so no individual command, file write, push or pull-request creation is shown to a human first; the project documents this as a design choice for unattended workflows. Workflows can include human approval gate nodes, but the bundled delivery workflow has none (the human gate is PR review on GitHub), and the chat assistant's run-management tool can itself approve or reject a paused gate. Changes happen in a git worktree by default, but pushes, PRs and anything done through the shell outside it are not reversible by Archon.
C3 Tool & action scoping
Minimal 0.05 / 1.00
Agents get the full Claude Code (or Codex) tool set: arbitrary shell commands, file writes anywhere the user can write, and web access, with no argument validation by Archon. Workflow authors can restrict each node to a list of allowed or denied tools, which is a useful coarse control, but the bundled workflows don't use it and it never inspects arguments. A misused tool reaches the whole machine.
C4 Code-execution isolation
Minimal 0.28 / 1.00
For repository projects, which is how most people use Archon, every workflow run happens in a separate git worktree, but that is a working directory, not a boundary: Claude Code, bash nodes and script nodes all run as the user on the host with the full environment and permission prompts off. A workflow file can also pin the worktree off. An opt-in Docker container backend exists for folder projects only; it keeps the host environment out and caps memory and processes, but has open network egress, runs as root inside, and on a standard Docker daemon falls back to a mode the project's own security notes describe as escapable.
C5 Untrusted input blast radius
Minimal 0.00 / 1.00
The bundled workflows read GitHub issues, pull requests and repository content and feed them to an agent that can run any shell command, push branches and open pull requests, all without a human in the loop. Nothing in code marks or limits content from those sources; the only defence is prompt wording asking the model to treat issue text as claims. If injected text hijacks a run, it can both leak the credentials and files the agent can see and take irreversible actions such as pushing code.
C6 Memory, context & configuration integrity
Minimal 0.00 / 1.00
Archon is designed so a repository carries its own automation: workflows, commands, scripts, an .archon/config.yaml (including environment variables and assistant settings), a repo-scope .archon/.env, and Claude Code project settings and CLAUDE.md are all loaded from the working checkout with no trust prompt. That means a cloned repository can add MCP servers, hooks and shell steps, and change how the agent is configured, simply by containing the right files; the project documents these sources as trusted. Conversation and run history persist in Archon's database and are scoped per project.
C7 Third-party extensions
Minimal 0.23 / 1.00
Archon's own plugins are installed explicitly from GitHub, pinned to a tag or commit, checked against the release's checksum file, and forge plugin processes get a scrubbed environment. MCP servers, Claude plugins and hooks are a different story: a workflow node can point at an MCP configuration in the repository, which is launched by whatever command it names, and that configuration can pull any environment variable into a server's environment or headers. Nothing verifies or confines these servers.
C8 Secrets & sensitive-data protection
Minimal 0.35 / 1.00
Archon has real secret hygiene in places: per-user provider and GitHub credentials are encrypted at rest with AES-256-GCM, never returned by the API, and bash/script output is redacted against secret-named environment values before it is logged or retained. But in the default setup secrets live in environment files and are passed whole to the agent and every subprocess, so the model can read them, and node output passed on to the next model step is not redacted. Anonymous, content-free telemetry is on by default with documented opt-outs.
C9 Audit & traceability
Minimal 0.45 / 1.00
Each workflow run writes a structured JSONL log and database events covering node starts and ends, provider tool calls, bash and script output, and gate decisions, stored under Archon's home directory rather than in the worktree. The record has no actor attribution for approvals, the agent runs as the same user and could edit it, and a logging failure only produces a single warning while the run carries on.
C10 Limits & kill switch
Minimal 0.33 / 1.00
Workflow structure bounds the overall run: loops must declare a maximum iteration count, sub-workflow nesting is capped, and bash and script steps time out after two minutes by default. Inside an AI step, though, nothing caps turns, time or spend by default: the 30-minute idle timer resets on any output and is described as a deadlock detector, and a dollar budget exists only if a workflow sets it. Cancelling a run aborts the in-flight provider call.
