# What is Coda?

> A code companion that lives in Slack and works alongside your team.

Coding agents write code. Coda handles the work around it: PR reviews, issue triage, feature planning, debugging. It lives in Slack as a teammate and works against your codebase on disk.

## The system

Coda is a multi-agent system:

| Member         | Role                                                     | Tools                                                                           |
| -------------- | -------------------------------------------------------- | ------------------------------------------------------------------------------- |
| **Explorer**   | Reads code, traces call chains                           | `CodingTools` (read-only), `GitTools`, `GithubTools`, `ReasoningTools`          |
| **Coder**      | Writes code in isolated worktrees, opens PRs             | `CodingTools` (full), `GitTools` (worktree), `GithubTools`, `ReasoningTools`    |
| **Planner**    | Breaks features into ordered GitHub issues               | `CodingTools` (read-only), `GitTools`, `GithubTools` (issues), `ReasoningTools` |
| **Researcher** | Hits the web for framework docs, library APIs, CVEs      | `ParallelTools`, `ReasoningTools`                                               |
| **Triager**    | Labels, comments, closes issues based on the actual code | `CodingTools` (read-only), `GithubTools` (issues), `ReasoningTools`             |
| **Leader**     | Routes the request, posts to Slack                       | `SlackTools`                                                                    |

The Coder works in a `coda/<branch>` git worktree off main. A human reviews and merges. Coda never merges. Worktrees clean up on restart.

## How Coda runs

Code is searched on disk. Grep, find, read against actual files, synced every five minutes. No vector indexing. No stale embeddings. Three scheduled tasks ship by default:

| Task             | Cadence         | What it does                                                               |
| ---------------- | --------------- | -------------------------------------------------------------------------- |
| **Repo Sync**    | Every 5 minutes | Pulls latest changes from every configured repo                            |
| **Daily Digest** | Each morning    | Posts what merged yesterday, PRs waiting, issues opened, what's gone stale |
| **Issue Triage** | Daily           | Reviews open issues against the actual code, labels them, posts a summary  |

Coda learns your conventions through [Agno's Learning Machine](/learning/overview). Week 1 you get generic patterns. Week 4 it follows your service layer style, error handling, naming, and logging.
