Copilot CLI

2026-07-20 An agentStop hook that always blocks no longer loops indefinitely: the CLI now ends the turn after 8 consecutive blocks, and agentStop hooks receive a stop_hook_active flag so they can detect a forced continuation and self-limit Add opt-in git and gh authentication inside the OS sandbox Sandbox macOS keychain access now defaults off for tighter isolation; re-enable it in /sandbox if a command needs it Lifecycle and subagent hook commands run in the current session directory after /cd Deleting an MCP server with /mcp delete stops its running background process Toggling /sandbox resta...

2026-07-16 copilot -p --autopilot no longer hangs when a background shell or agent outlives the turn; it now honors the COPILOT_TASK_WAIT_TIMEOUT_SECONDS timeout the same way plain -p does. Reopening the /subagents model picker keeps each agent's reasoning effort and context tier Refresh memory context after 30 minutes in long-lived sessions Keep MCP tool lists up to date when servers change Avoid leaving long-running background git processes after exit Add a configurable maximum for Ctrl+R command history On startup, an invalid settings.json now shows a warning identifying the offending value...

Added Persist GitHub MCP toolset/tool config via settings.json (githubMcpToolsets, githubMcpTools, etc.) Add plugins marketplace subcommands to list, add, and remove plugin marketplaces Persist sidebar sessions across restarts Add plugins marketplace browse and update commands Split /worktree and /move: /worktree now creates a new worktree and leaves your uncommitted changes behind, while the new /move carries them into the new worktree Add local and cloud cost profiles to /chronicle cost-tips Improved The /model picker shows the Auto model description as markdown with a clickable Learn More l...

2026-07-09 Add GPT-5.6 model support Show a single Error prefix for mcp and skill command failures Show the real parse error when --agent selects a malformed custom agent web_fetch works through mandatory HTTPS proxies Hide / search on the Gists tab Treat superseded subagent runs as cancellations instead of failures Add paginated session.mcp.resources read/list/listTemplates RPCs for MCP server resources preToolUse hooks that exit with code 2 deny tool calls Create draft skills when Forge finds a clear workflow pattern Hide the GitHub App install nudge in remote terminals Pin plugins to an exa...

Added Let built-in file edits bypass the sandbox when you approve it web_fetch now follows the active sandbox network policy (denying outbound or local targets the policy blocks) and, when the host opts in via sandbox.allowBypass, lets you approve a one-time bypass from the fetch prompt Show exact local assistant usage in Chronicle and session SQL Improved Improve /sandbox add-path suggestions so they open only when you ask for them Improve /chronicle cost-tips with more precise evidence-backed recommendations Hold Alt (Option on macOS) while scrolling to move one line at a time Resume and swi...

Added Add /mcp list to show attached MCP servers and their status, and allow /mcp list and /plugin list to run while the agent is working Allow opening the /mcp manager while the agent is working to enable or disable servers mid-turn; add, edit, delete, and re-auth stay paused until the turn finishes Add auto allow-all mode that auto-approves requests an LLM judge evaluates as acceptable Add a stayInAutopilot setting (default false) that keeps the CLI in autopilot mode after an autopilot task completes Improved Browse and filter models more easily in the CLI model picker Resume sessions faster...

2026-07-01 Add support for the kimi-k2.7-code model The focused field in the /mcp config form is marked with a "❯ " chevron, not color alone Keep IDE tools available during transient IDE disconnects, returning a clear error while disconnected and recovering automatically when the IDE reconnects Tab completion shows slash command aliases inline (e.g. /pr automerge|agentmerge) Stop hooks from erroring and denying every tool when a session's working directory or git worktree has been deleted Keep the footer model status in sync when reasoning effort or context tier changes Avoid duplicate skill a...

2026-06-30 Use a non-blinking block cursor during interactive sessions, restoring your terminal's default cursor on exit Add support for Claude Opus 4.8 Fast and deprecate Claude Opus 4.6 Fast MCP add/edit form accepts HTTP-style Key: value headers Keep LSP servers from starting twice during startup Avoid blocking commands that contain Windows-style path fragments Let Copilot read output from and stop detached background shell commands Large output handling now respects custom output directories and a disable setting Prevent PR description generation from crashing on empty assistant responses ...

Add persisted dynamicRetrieval setting (and --dynamic-retrieval skills=<on|off> flag) to enable or disable...

2026-06-23 Path access prompt shows resolved symlink targets so you can see exactly what access is being granted Show the pay-as-you-go additional usage budget at launch, refresh it after a request is rejected for hitting the additional spend limit, and show a friendly message when the additional usage limit is reached Add websocket responses support for BYOK OpenAI-compatible providers Resumed sessions reproduce the original attached-file references even if those files later change on disk, avoiding prompt-cache resets Free-text search terms containing colons (e.g. CLI: ) now return correct r...

2026-06-01 Actionable error message shown when GitHub API rate limit is hit during copilot update Plugin slash commands (/plugin install, uninstall, update, marketplace add/remove/browse) now show immediate feedback while the operation is in progress Canceling a running shell command (Ctrl+C on a !command, or aborting an agent command — including in sandboxed and background-promoted shells) now terminates the whole process tree instead of leaving orphaned processes running Canvas providers can return file:// URLs in open results for local file previews Symlinked directories appear in /cwd comp...
