Connect Codex to Devin

Wire Devin into an AI agent as a tool and it can hand off real engineering work instead of only describing it. The agent can open a Devin session for a task, send it messages and attachments as the job evolves, and check on, tag, or terminate the session on its own, calling each operation as a tool while it works. It can also curate the knowledge entries and playbooks Devin follows, so every session it starts begins with the right context.

What you can build

When a new bug report lands, create a Devin session with the details so it starts investigating without anyone opening a terminal.
When a Devin session finishes, post the result to your team chat and update the session tags so the outcome is easy to review.
Send a follow-up message to a running session with extra context or a correction pulled from a form submission.
Keep Devin's knowledge current by creating or updating knowledge entries whenever your team's coding guidelines change.
Store a third-party API token as a Devin secret before a session runs, then delete the secret once the task is complete.
Upload a spec or design file as an attachment to a session so Devin has the reference material it needs.

About Codex

Codex is OpenAI's command-line coding agent. NoClick runs it as a hosted agent and lets you connect your apps to it as tools, turning it from a coding assistant into an operator that can act across your systems. Connect an integration to the agent and Codex can query, create, and update records in that app directly. You keep the Codex experience and give it real reach into the tools your team already uses.

Fast, capable code generation and editing
Good at well-scoped, concrete tasks
Strong at API and data manipulation
Familiar to teams already on OpenAI tooling
