+# Instructions
+
+You are an edit prediction assistant in a code editor. Your task is to predict the next edit to a given region of code surrounding the user's cursor.
+
+1. Analyze the edit history to understand what the programmer is trying to achieve
+2. Identify any incomplete refactoring or changes that need to be finished
+3. Make the remaining edits that a human programmer would logically make next (by rewriting a region of code near their cursor)
+
+## Focus on
+
+- Completing any partially-applied changes made
+- Ensuring consistency with the programming style and patterns already established
+- Making edits that maintain or improve code quality
+
+## Rules
+
+- **NEVER undo or revert the user's recent edits.** Examine the diff in the edit history carefully:
+  - If a line was removed (starts with `-`), do NOT restore that content—even if the code now appears incomplete or broken without it
+  - If a line was added (starts with `+`), do NOT delete or significantly modify it
+  - If code appears broken or incomplete after the user's edit, output `NO_EDITS` rather than "fixing" it by reverting
+  - Only add NEW content that extends the user's work forward; never restore what they removed
+  - **Key test**: if your prediction would make the code more similar to what it was BEFORE the user's edit, output `NO_EDITS` instead
+  - **Never assume a deletion was accidental.** Even if removing content breaks the code, breaks a pattern, or leaves text looking "incomplete", respect it. The user may be mid-rewrite. Do NOT "complete" partial text by restoring what was deleted.
+- Auto-generated code can be modified: Hunks marked with `// User accepted prediction:` contain code from a previous prediction the user accepted. Unlike user-typed content, these hunks CAN be edited, corrected, or replaced if it improves the code. The "never undo/revert" rule protects the user's *current typing intent*—auto-generated code doesn't carry this protection
+- Do not just mechanically apply patterns - reason about what changes make sense given the context and the programmer's apparent goals.
+- Do not just fix syntax errors - look for the broader refactoring pattern and apply it systematically throughout the code.
+- Keep existing formatting unless it's absolutely necessary
+- When edit history and surrounding code suggest different edits, prioritize the most recent edits in the history as they best reflect current intent.
+- Treat partial text at or near the cursor as the beginning of something the user is actively typing. Complete the code the user appears to be creating based on context.
+- When completing partial code, prefer predictions that save meaningful keystrokes, even if this requires making educated guesses about the user's intent.
+- For code, it's better to make a substantive prediction that might be rejected than to make a minimal prediction that saves only a few keystrokes.
+- When the user is editing prose or documentation (e.g. Markdown, comments, plain text), predict conservatively. Complete the current fragment or sentence, but do not generate additional lines of free-form content since prose is less constrained than code and more prone to incorrect continuations.
+
+# Input Format
+
+You will be provided with:
+1. The user's *edit history*, in chronological order. Use this to infer the user's trajectory and predict the next most logical edit.
+  - Hunks preceded by `// User accepted prediction:` indicate code that was auto-generated by a previous prediction and accepted by the user. These are treated differently than user-typed edits (see Rules).
+2. A set of *related excerpts* from the user's codebase. Some of these may be needed for correctly predicting the next edit.
+  - `…` may appear within a related file to indicate that some code has been skipped.
+3. An excerpt from the user's *current file*.
+    - The excerpt contains numbered *marker* tags (`<|marker_1|>`, `<|marker_2|>`, etc.) placed at block boundaries throughout the code. These markers divide the excerpt into spans that you can target for editing.
+    - Code that appears before the first marker or after the last marker is read-only context and cannot be edited.
+    - The `<|user_cursor|>` tag marks the user's current cursor position, as it stands after the last edit in the history.
+
+# Output Format
+
+- Briefly explain the user's current intent based on the edit history and their current cursor location.
+- Output a markdown codeblock containing your predicted edit as a **marker-bounded span**:
+  - The codeblock must **start** with a marker tag (e.g. `<|marker_2|>`) and **end** with a marker tag (e.g. `<|marker_4|>`).
+  - The content between these two markers is the full replacement for that span in the original file.
+  - Choose the **narrowest** pair of markers that fully contains your predicted edits, to minimize unnecessary output.
+  - Reproduce any unchanged lines within the chosen span faithfully — do not omit or alter them.
+  - Do not include any intermediate marker tags in your output — only the start and end markers.
+- If no edit is needed (the code is already complete and correct, or there is no clear next edit to make), output a codeblock containing only `NO_EDITS`:
+  `````
+  NO_EDITS
+  `````
+- If there is a specific place in the predicted output where the user is likely to edit next, indicate it using the `<|user_cursor|>` tag.
+
+## Example 1
+
+There is code missing at the cursor location. The related excerpts includes the definition of a relevant type. You should fill in the missing code.

+//! A clean testing API for GPUI applications.
+//!
+//! `TestApp` provides a simpler alternative to `TestAppContext` with:
+//! - Automatic effect flushing after updates
+//! - Clean window creation and inspection
+//! - Input simulation helpers
+//!
+//! # Example
+//! ```ignore
+//! #[test]
+//! fn test_my_view() {
+//!     let mut app = TestApp::new();
+//!
+//!     let mut window = app.open_window(|window, cx| {

+//!
+//!     window.update(|view, window, cx| {
+//!         view.do_something(cx);
+//!     });
+//!
+//!     // Check rendered state
+//!     assert_eq!(window.title(), Some("Expected Title"));

+//! This type ensures that all rows in a table have the same width, preventing accidental creation or mutation of rows with inconsistent lengths.
+//! It is especially useful for CSV or tabular data where rectangular invariants must be maintained, but the number of columns is only known at runtime.
+//! By using `TableRow`, we gain stronger guarantees and safer APIs compared to a bare `Vec<T>`, without requiring const generics.

+## Voice and Tone
+
+### Core Principles
+
+- **Practical over promotional**: Focus on what users can do, not on selling Zed. Avoid marketing language like "powerful," "revolutionary," or "best-in-class."
+- **Honest about limitations**: When Zed lacks a feature or doesn't match another tool's depth, say so directly. Pair limitations with workarounds or alternative workflows.
+- **Direct and concise**: Use short sentences. Get to the point. Developers are scanning, not reading novels.
+- **Second person**: Address the reader as "you." Avoid "the user" or "one."
+- **Present tense**: "Zed opens the file" not "Zed will open the file."
+
+### What to Avoid
+
+- Superlatives without substance ("incredibly fast," "seamlessly integrated")
+- Hedging language ("simply," "just," "easily")—if something is simple, the instructions will show it
+- Apologetic tone for missing features—state the limitation and move on
+- Comparisons that disparage other tools—be factual, not competitive
+- Lots of use of em or en dashes.
+
+## Examples of Good Copy
+
+### Good: Direct and actionable
+
+```
+To format on save, open the Settings Editor (`Cmd+,`) and search for `format_on_save`. Set it to `on`.
+
+Or add this to your settings.json:
+{
+  "format_on_save": "on"
+}
+```
+
+### Bad: Wordy and promotional
+
+```
+Zed provides a powerful and seamless formatting experience. Simply navigate to the settings and you'll find the format_on_save option which enables Zed's incredible auto-formatting capabilities.
+```
+
+### Good: Honest about limitations
+
+```
+Zed doesn't index your project like IntelliJ does. You open a folder and start working immediately—no waiting. The trade-off: cross-project analysis relies on language servers, which may not go as deep.
+
+**How to adapt:**
+- Use `Cmd+Shift+F` for project-wide text search
+- Use `Cmd+O` for symbol search (powered by your language server)
+```
+
+### Bad: Defensive or dismissive
+
+```
+While some users might miss indexing, Zed's approach is actually better because it's faster.

+# Plan: Show ACP Threads in the Sidebar (Revised)
+
+## Problem
+
+The sidebar currently only shows **Zed-native agent threads** (from `ThreadStore`/`ThreadsDatabase`). ACP threads (Claude Code, Codex, Gemini, etc.) are invisible in the sidebar once they're no longer live.
+
+## Root Cause
+
+`ThreadStore` and `ThreadsDatabase` only persist metadata for native threads. When `rebuild_contents` populates the sidebar, it reads from `ThreadStore` for historical threads and overlays live info from the `AgentPanel` — but non-native threads never get written to `ThreadStore`, so once they stop being live, they disappear.
+
+## Solution Overview (Revised)
+
+**Key change from the original plan:** We completely remove the sidebar's dependency on `ThreadStore`. Instead, the `Sidebar` itself owns a **single, unified persistence layer** — a new `SidebarDb` domain stored in the workspace DB — that tracks metadata for _all_ thread types (native and ACP). The sidebar becomes the single source of truth for what threads appear in the list.
+
+### Why Remove the ThreadStore Dependency?
+
+1. **Single responsibility** — The sidebar is the only consumer of "which threads to show in the list." Having it depend on `ThreadStore` (which exists primarily for native agent save/load) creates an indirect coupling that makes ACP integration awkward.
+2. **No merge logic** — The original plan required merging native `ThreadStore` data with a separate `AcpThreadMetadataDb` in `ThreadStore::reload`. By moving all sidebar metadata into one place, there's nothing to merge.
+3. **Simpler data flow** — Writers (native agent, ACP connections) push metadata to the sidebar DB. The sidebar reads from one table. No cross-crate coordination needed.
+4. **ThreadStore stays focused** — `ThreadStore` continues to manage native thread blob storage (save/load message data) without being polluted with sidebar display concerns.
+
+### Architecture

+
+## Step 1: Create `SidebarDb` Domain in `sidebar.rs`
+
+**File:** `crates/agent_ui/src/sidebar.rs`
+
+Add a `SidebarDb` domain using `db::static_connection!`, co-located in the sidebar module (or a small `persistence` submodule within `sidebar.rs` if it helps organization, but keeping it in the same file is fine for now).

+};

+                session_id: acp::SessionId::new(id),
+                agent_name,
+                title: title.into(),
+                updated_at,
+                created_at,
+                folder_paths,
+            },
+            next,
+        ))
+    }
+}
+```
+
+**Key points:**
+
+- `SIDEBAR_DB` is a `LazyLock` static — initialized on first use, no manual connection management.
+- The `agent_name` column is `NULL` for native Zed threads and a string like `"claude-code"` for ACP agents. This replaces the `agent_type` field from the original plan.
+- The DB file lives alongside other `static_connection!` databases.
+- `ThreadsDatabase` and `ThreadStore` are **completely unchanged** by this step.
+
+---
+
+## Step 2: Replace `ThreadStore` Reads in `rebuild_contents` with `SidebarDb` Reads
+
+**File:** `crates/agent_ui/src/sidebar.rs`
+
+### Remove `ThreadStore` Dependency
+
+1. **Remove** `ThreadStore::global(cx)` and `ThreadStore::try_global(cx)` from `Sidebar::new` and `rebuild_contents`.
+2. **Remove** the `cx.observe_in(&thread_store, ...)` subscription that triggers `update_entries` when `ThreadStore` changes.
+3. **Replace** `thread_store.read(cx).threads_for_paths(&path_list)` calls with `SIDEBAR_DB.list_for_paths(&path_list)` (or read all rows once at the top of `rebuild_contents` and index them in memory, which is simpler and avoids repeated DB calls).
+
+### New Data Flow in `rebuild_contents`
+
+```rust
+fn rebuild_contents(&mut self, cx: &App) {
+    // ... existing workspace iteration setup ...
+
+    // Read ALL sidebar thread metadata once, index by folder_paths.
+    let all_sidebar_threads = SIDEBAR_DB.list().unwrap_or_default();
+    let mut threads_by_paths: HashMap<PathList, Vec<SidebarThreadRow>> = HashMap::new();
+    for row in all_sidebar_threads {
+        threads_by_paths
+            .entry(row.folder_paths.clone())
+            .or_default()
+            .push(row);
+    }
+
+    for (ws_index, workspace) in workspaces.iter().enumerate() {
+        // ... existing absorbed-workspace logic ...
+
+        let path_list = workspace_path_list(workspace, cx);
+
+        if should_load_threads {
+            let mut seen_session_ids: HashSet<acp::SessionId> = HashSet::new();
+
+            // Read from SidebarDb instead of ThreadStore
+            if let Some(rows) = threads_by_paths.get(&path_list) {
+                for row in rows {
+                    seen_session_ids.insert(row.session_id.clone());
+                    let (agent, icon) = match &row.agent_name {
+                        None => (Agent::NativeAgent, IconName::ZedAgent),
+                        Some(name) => (
+                            Agent::Custom { name: name.clone().into() },
+                            IconName::ZedAgent, // placeholder, resolved in Step 5
+                        ),
+                    };
+                    threads.push(ThreadEntry {
+                        agent,
+                        session_info: AgentSessionInfo {
+                            session_id: row.session_id.clone(),
+                            cwd: None,
+                            title: Some(row.title.clone()),
+                            updated_at: Some(row.updated_at),
+                            created_at: row.created_at,
+                            meta: None,
+                        },
+                        icon,
+                        icon_from_external_svg: None,
+                        status: AgentThreadStatus::default(),
+                        workspace: ThreadEntryWorkspace::Open(workspace.clone()),
+                        is_live: false,
+                        is_background: false,
+                        highlight_positions: Vec::new(),
+                        worktree_name: None,
+                        worktree_highlight_positions: Vec::new(),
+                        diff_stats: DiffStats::default(),
+                    });
+                }
+            }
+
+            // ... existing linked git worktree logic, also reading from threads_by_paths ...
+            // ... existing live thread overlay logic (unchanged) ...
+        }
+    }
+}
+```
+
+### What Changes
+
+- `rebuild_contents` reads from `SIDEBAR_DB` instead of `ThreadStore`.
+- The `ThreadEntry.agent` field now carries `Agent::Custom { name }` for ACP threads, enabling correct routing in `activate_thread`.
+- The live thread overlay logic (from `all_thread_infos_for_workspace`) is **unchanged** — it still reads from `AgentPanel` to get real-time status of running threads.
+
+### What Stays the Same
+
+- The entire workspace/absorbed-workspace/git-worktree structure.
+- The live thread overlay pass.
+- The notification tracking logic.
+- The search/filter logic.
+
+---
+
+## Step 3: Write Native Thread Metadata to `SidebarDb`
+
+**File:** `crates/agent_ui/src/sidebar.rs` and/or `crates/agent_ui/src/agent_panel.rs`
+
+When a native thread is saved (after conversation, on title update, etc.), we also write its metadata to `SidebarDb`. There are two approaches:
+
+### Option A: Subscribe to `ThreadStore` Changes (Recommended)
+
+Keep a one-directional sync: when `ThreadStore` finishes a `save_thread` or `reload`, the sidebar syncs the metadata to `SidebarDb`. This can be done in the sidebar's workspace subscription or by observing `ThreadStore` changes purely for the purpose of syncing (not for reading).
+
+```rust
+// In Sidebar::subscribe_to_workspace or a dedicated sync method:
+fn sync_native_threads_to_sidebar_db(&self, cx: &App) {
+    if let Some(thread_store) = ThreadStore::try_global(cx) {
+        let entries: Vec<_> = thread_store.read(cx).entries().collect();
+        cx.background_spawn(async move {
+            for meta in entries {
+                SIDEBAR_DB.save(&SidebarThreadRow {
+                    session_id: meta.id,
+                    agent_name: None, // native
+                    title: meta.title,
+                    updated_at: meta.updated_at,
+                    created_at: meta.created_at,
+                    folder_paths: meta.folder_paths,
+                }).await.log_err();
+            }
+        }).detach();
+    }
+}
+```
+
+### Option B: Write at the Point of Save
+
+In `AgentPanel` or wherever `thread_store.save_thread()` is called, also call `SIDEBAR_DB.save(...)`. This is more direct but requires touching more call sites.
+
+**Recommendation:** Option A is simpler for the initial implementation. We observe `ThreadStore` changes, diff against `SidebarDb`, and sync. Later, if we want to remove `ThreadStore` entirely from the write path for native threads, we can switch to Option B.
+
+---
+
+## Step 4: Write ACP Thread Metadata to `SidebarDb`
+
+**File:** `crates/agent_ui/src/connection_view.rs` (or `agent_panel.rs`)
+
+When ACP sessions are created, updated, or listed, write metadata directly to `SidebarDb`:
+
+- **On new session creation:** After `connection.new_session()` returns the `AcpThread`, call `SIDEBAR_DB.save(...)`.
+- **On title update:** ACP threads receive title updates via `SessionInfoUpdate`. When these come in, call `SIDEBAR_DB.save(...)` with the new title and updated timestamp.
+- **On session list refresh:** When `AgentSessionList::list_sessions` returns for an ACP agent, bulk-sync the metadata into `SidebarDb`.
+
+After any write, call `cx.notify()` on the `Sidebar` entity (or use a channel/event) to trigger a `rebuild_contents`.
+
+### Triggering Sidebar Refresh
+
+Since the sidebar no longer observes `ThreadStore`, we need a mechanism to trigger `rebuild_contents` after DB writes. Options:
+
+1. **Emit an event from `AgentPanel`** — The sidebar already subscribes to `AgentPanelEvent`. Add a new variant like `AgentPanelEvent::ThreadMetadataChanged` and emit it after saving to `SidebarDb`.
+2. **Use `cx.notify()` directly** — If the save happens within a `Sidebar` method, just call `self.update_entries(cx)`.
+3. **Observe a lightweight signal entity** — A simple `Entity<()>` that gets notified after DB writes.
+
+**Recommendation:** Option 1 (emit from `AgentPanel`) is cleanest since the sidebar already subscribes to panel events.
+
+---
+
+## Step 5: Handle Agent Icon Resolution for ACP Threads
+
+**File:** `crates/agent_ui/src/sidebar.rs`
+
+For ACP threads in the sidebar, we need the correct agent icon. The `agent_name` string stored in `SidebarDb` maps to an agent in the `AgentServerStore`, which has icon info.
+
+In `rebuild_contents`, after building the initial thread list from `SidebarDb`, resolve icons for ACP threads:
+
+```rust
+// For ACP threads, look up the icon from the agent server store
+if let Some(name) = &row.agent_name {
+    if let Some(agent_server_store) = /* get from workspace */ {
+        // resolve icon from agent_server_store using name
+    }
+}
+```
+
+---
+
+## Step 6: Handle Delete Operations Correctly
+
+**File:** `crates/agent_ui/src/sidebar.rs`
+
+When the user deletes a thread from the sidebar:
+
+- **All threads** → Delete from `SidebarDb` via `SIDEBAR_DB.delete(session_id)`.
+- **Native threads** → _Also_ delete from `ThreadStore`/`ThreadsDatabase` (to clean up the blob data).
+- **ACP threads** → Optionally notify the ACP server via `AgentSessionList::delete_session`.
+
+The `agent_name` field on `SidebarThreadRow` (or the `Agent` enum on `ThreadEntry`) tells us which path to take.
+
+When the user clears all history:
+
+```rust
+// Delete all sidebar metadata
+SIDEBAR_DB.delete_all().await?;
+// Also clear native thread blobs
+thread_store.delete_threads(cx);
+// Optionally notify ACP servers
+```
+
+---
+
+## Step 7: Handle `activate_thread` Routing
+
+**File:** `crates/agent_ui/src/sidebar.rs`, `crates/agent_ui/src/agent_panel.rs`
+
+In `activate_thread`, branch on the `Agent` variant:
+
+- `Agent::NativeAgent` → Call `panel.load_agent_thread(Agent::NativeAgent, session_id, ...)` (current behavior).
+- `Agent::Custom { name }` → Call `panel.load_agent_thread(Agent::Custom { name }, session_id, ...)` so it routes to the correct `AgentConnection::load_session`.
+
+This is already partially set up — `activate_thread` takes an `Agent` parameter. The key change is that `ThreadEntry` now carries the correct `Agent` variant based on `SidebarThreadRow.agent_name`.
+
+---
+
+## Step 8: Handle `activate_archived_thread` Without ThreadStore
+
+**File:** `crates/agent_ui/src/sidebar.rs`
+
+Currently, `activate_archived_thread` looks up `saved_path_list` from `ThreadStore`:
+
+```rust
+let saved_path_list = ThreadStore::try_global(cx).and_then(|thread_store| {
+    thread_store
+        .read(cx)
+        .thread_from_session_id(&session_info.session_id)
+        .map(|thread| thread.folder_paths.clone())
+});
+```
+
+Replace this with a targeted `SidebarDb::get` lookup (single-row SELECT, no full table scan):
+
+```rust
+let saved_path_list = SIDEBAR_DB
+    .get(&session_info.session_id)
+    .ok()
+    .flatten()
+    .map(|row| row.folder_paths);
+```
+
+---
+
+## Step 9: Error Handling for Offline Agents
+
+When an ACP thread is clicked but the agent server is not running:
+
+- Show a toast/notification explaining the agent is offline.
+- Keep the metadata in the sidebar (don't remove it).
+- Optionally offer to start the agent server.
+
+---
+
+## Step 10: Migration — Backfill Existing Native Threads
+
+On first launch after this change, the `SidebarDb` will be empty while `ThreadsDatabase` has existing native threads. We need a one-time backfill:
+
+```rust
+// In Sidebar::new or a dedicated init method:
+fn backfill_native_threads_if_needed(cx: &App) {
+    if SIDEBAR_DB.count()  > 0 {
+        return; // Already populated
+    }
+
+    if let Some(thread_store) = ThreadStore::try_global(cx) {
+        let entries: Vec<_> = thread_store.read(cx).entries().collect();
+        cx.background_spawn(async move {
+            for meta in entries {
+                SIDEBAR_DB.save(&SidebarThreadRow {
+                    session_id: meta.id,
+                    agent_name: None,
+                    title: meta.title,
+                    updated_at: meta.updated_at,
+                    created_at: meta.created_at,
+                    folder_paths: meta.folder_paths,
+                }).await.log_err();
+            }
+        }).detach();
+    }
+}
+```

+Extensions may provide snippets for one or more languages.
+
+Each file containing snippets can be specified in the `snippets` field of the `extensions.toml` file.
+
+The referenced path must be relative to the `extension.toml`.
+
+## Defining Snippets
+
+A given extension may provide one or more snippets. Each snippet must be registered in the `extension.toml`.
+
+Zed matches snippet files based on the lowercase name of the language (e.g. `rust.json` for Rust).
+You can use `snippets.json` as a file name to define snippets that will be available regardless of the current buffer language.
+
+For example, here is an extension that provides snippets for Rust and TypeScript:
+
+```toml
+snippets = ["./snippets/rust.json", "./snippets/typescript.json"]
+```

+## Initialization Options
+
+### Specifying location of TypeScript SDK
+
+By default, this extension assumes that you are working in a project with a `node_modules` directory, and searches for
+the TypeScript SDK inside that directory.
+
+This may not always be true; for example, when working in a project that uses Yarn PnP, there is no `node_modules`. For
+editor support, the [documented](https://yarnpkg.com/getting-started/editor-sdks) approach is to run something like
+`yarn dlx @yarnpkg/sdks`. In that case, you can provide the following initialization options in your Zed settings:
+
+```json
+{
+  "lsp": {
+    "vue": {
+      "initialization_options": {
+        "typescript": {
+          "tsdk": ".yarn/sdks/typescript/lib"
+        }
+      }
+    }
+  }
+}
+```
+
+## Settings Options
+
+`lsp.vue.settings` is passed through to the Vue language server (Volar / [`vuejs/language-tools`](https://github.com/vuejs/language-tools)). The following settings are enabled by default:
+
+```json
+{
+  "lsp": {
+    "vue": {
+      "settings": {
+        // Display inlay hints for the `$event` parameter in inline event handlers.
+        "vue.inlayHints.inlineHandlerLeading": true,
+        // Display hints when required component props are missing in templates.

+        "vue.inlayHints.vBindShorthand": true

+# Roles

+what they can access and configure.
+
+## Role Types {#roles}
+
+Every member of an organization is assigned one of three roles:
+
+| Role       | Description                                            |

+| **Member** | Standard access, no privileged actions                 |
+
+### Owner {#role-owner}
+
+An owner has full control over the organization, including:
+
+- Invite and remove members
+- Assign and change member roles
+- Manage billing, payment methods, and invoices
+- Configure data-sharing policies
+- Disable Zed's collaborative features
+- Control whether members can use Zed-hosted models and Zed's edit predictions
+- Transfer ownership to another member
+
+### Admin {#role-admin}
+
+Admins have the same capabilities as the Owner, except they cannot:
+
+- Access or modify billing settings
+- Transfer organization ownership
+
+This role is suited for team leads or managers who handle day-to-day
+member access without needing visibility into payment details.
+
+### Member {#role-member}
+
+Members have standard access to Zed. They cannot access billing or
+organization settings.
+
+## Managing User Roles {#managing-users}
+
+Owners and Admins can manage organization members from the Zed
+dashboard within the Members page.
+
+### Inviting Members {#inviting-members}
+
+1. On the Members page, select **+ Invite Member**.
+2. Enter the member's company email address and choose a role.
+3. The invitee receives an email with instructions to join. After
+   accepting, they authenticate via GitHub.
+
+### Changing a Member's Role {#changing-roles}
+
+1. On the Members page, find the member. You can filter by role or
+   search by name.
+2. Open the three-dot menu and select a new role.
+
+### Removing a Member {#removing-members}
+
+1. On the Members page, find the member.
