the-loop CLI
A lightweight, extensible command-line companion to the-loop — an opinionated product-development-lifecycle harness shipped as a Claude Code and Cursor plugin.
The plugin is the operating model an agent follows inside a session. This CLI is what starts those sessions, keeps them attached to work items, and tells you what happened: a GitHub webhook receiver and a poller that turn ticket activity into agent runs, a session registry, execution control, a structured event log, and repo-scoped commands for the process graph, critic rounds and test-scenario discovery.
Written in Python with one runtime dependency, PyYAML — its whole configuration is YAML, so reading it is not optional — and stdlib otherwise. Python is intentional: it leaves room to add self-learning / ML capabilities later, which are mostly exposed as Python SDKs.
Install
Published to PyPI as the-loopy-one — the base name the-loop was taken. The import
package and the console script keep the natural the_loop / the-loop:
pip install the-loopy-one # PyYAML comes with it — nothing else to add
the-loop --help
From there the CLI installs the rest of the-loop — and upgrades itself:
the-loop install # this CLI + detected Claude Code and Codex setup (Cursor: issue #157)
the-loop install codex --scope project --project-dir .
the-loop upgrade # move both to the current release
the-loop install claude --scope project --project-dir . # one repository only
upgrade uses the installer that owns the copy you are running (uv tool, pipx,
pip), and --dry-run prints the exact commands first.
No extras: one pip install the-loopy-one brings everything, including hosting the
control-plane service and its MCP endpoint. ([service], [slack] and [config] are
deprecated no-ops, kept so pinned install lines keep resolving.) Needs Python 3.10+.
In one minute
# 1. Tell the daemon who may drive it, in ~/.the-loop/cli-config.yaml
# routing.authorizedUsers: ["your-github-login"]
# polling.enabled: true # polling needs no inbound networking
# polling.sources: [{ provider: github, repos: ["your-org/your-repo"] }]
# 2. Bring the-loop up: starts every service the config enables — here the
# control-plane service and the poller — detached, logging under .the-loop/logs/.
the-loop start
# 3. Label a GitHub issue "the-loop: auto-execute", then comment:
# the-loop start
# 4. Watch
the-loop status # per-service liveness + the poller's last cycle (exit 0/1)
the-loop sessions list
the-loop events --follow
Or embed it
The package is importable, so the control plane can live inside a Python service you already run instead of a process of its own:
from fastapi import Depends, FastAPI
from the_loop.sdk import TheLoop
loop = TheLoop(config_path="/etc/the-loop/cli-config.yaml")
app = FastAPI()
loop.mount(app, prefix="/the-loop", dependencies=[Depends(verify_caller)])
Same router as the-loop start serves, under your prefix, behind your auth and middleware.
The capabilities work with no HTTP at all (loop.work_items.list()), and
loop.check_environment() says at startup which external binaries your configuration needs.
See the SDK docs.
Documentation

| Overview | What the CLI is, and when you need it |
| Installation | PyPI, uv, extras, what else to have on PATH |
| Getting started | Zero to an auto-executing work item, in five steps |
| Concepts | Ingress, sessions, guards, workspaces, the process graph |
| Commands | gh-webhook · poll · sessions · events · check · graph · critic · scenarios · instructions · install · upgrade · migrate-config |
| Configuration | Every option, by area, with types and defaults |
| Adding a command | The Command / @register contract |
| Python SDK | The same package, imported: mount the control plane into your own FastAPI service, or call the capabilities directly |
Two config files, and they never overlap. The CLI reads
cli-config.yamland nothing else (yours, machine-scoped, resolved via--config→$THE_LOOP_CLI_CONFIG→./.the-loop/cli-config.yaml→~/.the-loop/cli-config.yaml): ingress, routing, the spec directory, the critics, the graph hooks. A repository's.the-loop/harness-config.yamlis the agent's config and is never read by the CLI (issue-352, decision-123). See Configuring the-loop.
Development
the-loop uses uv. From the repository root:
uv sync # install the workspace from uv.lock
uv run the-loop --help
make test # pytest
make check # ruff · pyright · schema validation · pytest
Releases are automatic: on merge to main, cz bump derives the next version from the
Conventional Commits since the last tag and publishes to PyPI via Trusted Publishing
(OIDC — no stored token).
