# Devin CLI

> Asymptote support details for Devin CLI endpoint telemetry

## Runtime Overview

Asymptote supports Devin CLI through native Devin hook payloads sent to `beacon-hooks`.

## Prerequisites

Before enabling Devin CLI hooks, make sure:

* Devin CLI is installed for the user or configured in the project where hooks will run.
* `beacon endpoint install` has run so shared endpoint config and runtime log paths exist.
* Asymptote hooks are installed with `beacon endpoint hooks install --harness devin-cli`. The legacy `devin` harness name still maps to Devin CLI.
* For project-level collection, install hooks from the target project with `--level project`.
* Devin CLI is restarted after hook install or removal so new sessions load the updated hook configuration.

## Collection path

Devin CLI invokes Asymptote's hook adapter from hook entries in Devin configuration. The adapter writes normalized endpoint events to the configured runtime JSONL log.

## Discovery and status

Asymptote detects Devin CLI through the `devin` executable, `~/.config/devin`, or `./.devin`, then checks Asymptote hook configuration.

Use `beacon endpoint hooks status --harness devin-cli` to inspect Devin CLI hook status.

## Install or configuration support

`beacon endpoint install` prepares shared endpoint config and runtime log paths. Install Devin CLI hooks separately:

```bash title="Install runtime hooks" theme={null}
beacon endpoint hooks install --harness devin-cli
```

For project-level Devin CLI hooks, run:

```bash title="Install project-level Devin CLI hooks" theme={null}
beacon endpoint hooks install --harness devin-cli --level project
```

## Telemetry coverage

| Area                              | Support                                                                                                                                                  |
| --------------------------------- | -------------------------------------------------------------------------------------------------------------------------------------------------------- |
| Prompt telemetry                  | Supported through `UserPromptSubmit` hooks                                                                                                               |
| Command, tool, and file telemetry | Supported for session, prompt, pre-tool, post-tool, permission request, stop, session-end, approval, and file telemetry where Devin CLI exposes payloads |
| Local JSONL and dashboard         | Supported                                                                                                                                                |
| MDM deployment                    | Supported for the endpoint agent; Devin CLI hooks are installed separately in the logged-in user's context or project context                            |

## Deployment notes

Asymptote writes Devin CLI user-level hooks under the `hooks` key in `~/.config/devin/config.json`. Devin CLI project-level installs write the standalone hook map to `./.devin/hooks.v1.json`.

Install and uninstall preserve unrelated Devin settings and non-Asymptote hook commands. Restart Devin CLI after installing or removing hooks so new sessions pick up the updated hook configuration.
