2+title: Projects
3+description: A repository as a project for agent work, with a task board, a conversation, shared memory, project instructions and a limit on how many tasks run at once.
4+---
5+
6+Every repository is also a **project** for agent work. Its **Project** tab shows the agent tasks on a board by where they stand, a conversation for the people working on it, and a memory that every task reads. Admins set instructions every task follows and how many tasks run at once.
7+
8+Nothing here changes Git, pull requests or Actions. A repository that runs no [agent tasks](/docs/agents/tasks) just has an empty board.
9+
10+The Project tab is for people with **write** access, like tasks.
11+
12+## The board
13+
14+Each task sits in one column, by its own state first and then by its pull request's:
15+
16+| Column | Tasks in it |
17+| --- | --- |
18+| **Waiting on you** | The task failed, or its pull request has failing checks. |
19+| **Working** | The agent is running, or the pull request's checks are. |
20+| **Queued** | Waiting for a running task to finish (see [How many at once](#how-many-at-once)). |
21+| **Ready for review** | The pull request is open and its checks passed, or it has none. |
22+| **Landing** | The pull request is approved on its latest commit, set to auto-merge, or in the merge queue. |
23+| **Done** | The pull request was merged. |
24+| **Idle** | Finished with nothing to review, stopped, or its pull request was closed. |
25+
26+Done and Idle show their latest tasks; **All tasks** lists every one. [Agent reviews](/docs/agents/review) don't show on the board: they belong to their pull requests.
27+
28+## Conversation
29+
30+The conversation is a shared timeline for the project. People with write access post ideas, plans and notes, in Markdown. Tasks add a line when they start, open a pull request, finish with no changes, fail or stop.
31+
32+**Start a task** on a post opens a new task with the post as its goal, so an idea can become work in one step.
33+
34+Posting needs a browser session. Tokens can read the conversation over the [REST API](#rest-api) and [MCP](#mcp), but not post to it.
35+
36+## Memory
37+
38+Memory is a Markdown document of notes that every agent task in the project reads: conventions, decisions, where things are. Open it from the side of the Project tab.
39+
40+- A task gets the memory in its prompt with its goal, marked as background notes, not as instructions.
41+- Agent reviews don't read it.
42+- Each save keeps a version. The last 50 are kept, and opening one shows how restoring it would change the current memory. **Restore this version** saves it as a new version, so a restore can be undone too.
43+- Memory is up to 40,000 characters. Don't put secrets in it: every task's agent and its sandbox see it.
44+
45+## Settings
46+
47+Repository admins set these under **Settings → Project**.
48+
49+### Project instructions
50+
51+Text every agent task and [agent review](/docs/agents/review) in the repository gets in its prompt: for example, which tests to run before opening a pull request. Up to 10,000 characters. Reviews also follow `REVIEW.md` files.
52+
53+### How many at once
54+
55+How many tasks run at the same time in the repository, from 1 to 10. The default is 3. A task started beyond it is **Queued**: its page says so, and it starts, oldest first, when a running task finishes or stops, or when an admin raises the number. Follow-ups and retries queue the same way. Agent reviews don't count toward the number and never wait.
56+

8789
8890 - **Fix it** appears under every finding for people with write access. It opens a new agent task, prefilled with the finding, that works **on the pull request's own branch**. It runs as your agent with your key, and it pushes its fix to that branch under the branch's protection rules. The next review then checks the fix.
