AI Coding News: July 10, 2026 — Copilot CLI Adds GPT-5.6 as Four Tools Ship in One Day

Four different AI coding CLIs shipped new releases inside the same 24-hour window on July 9, 2026: GitHub Copilot CLI landed GPT-5.6 support, Claude Code climbed to v2.1.206, OpenCode pushed three builds in a row, and OpenAI's Codex CLI — new to this roundup — picked up a stricter approval mode. Here's what actually changed in each one.

GitHub Copilot CLI v1.0.70: GPT-5.6 Lands With Session-Scoped Sandbox Toggles

GitHub shipped Copilot CLI v1.0.70 on July 9, its second release in three days after v1.0.69's plugin dashboard. The headline addition is GPT-5.6 model support, paired with a batch of sandbox and workflow changes:

• New --sandbox and --no-sandbox flags flip the OS-level shell sandbox on or off for a single session without touching the saved setting — useful with non-interactive -p runs.
• A new /refine command rewrites a rough, stream-of-consciousness prompt into a clear one before it's sent.
• Plugins can now be pinned to an exact commit SHA via the sha field in plugin source configuration.
• A trusted repository can pin the model, effort level, and context tier, and extend the URL/MCP/skill deny lists, through a new .github/copilot/settings.json file.
• preToolUse hooks that exit with code 2 now deny the tool call outright, giving hook authors a hard veto.
• New paginated session.mcp.resources RPCs let SDK clients read, list, and list templates for MCP server resources.

Claude Code v2.1.206: /doctor Now Suggests a CLAUDE.md Diet

Anthropic shipped Claude Code v2.1.206 on July 9, one day after v2.1.205's rm -rf safety guard. This build leans toward workflow polish and a long tail of fixes:

• A new /doctor check proposes trimming checked-in CLAUDE.md files by cutting content Claude could already derive from the codebase itself.
• /cd now offers directory path suggestions, matching the existing /add-dir behavior.
• /commit-push-pr auto-allows git push to the repo's configured push remote (remote.pushDefault, or the sole remote when only one exists), not just origin.
• /login now supports Anthropic-operated public gateway endpoints, and EnterWorktree asks for confirmation before entering a worktree outside the project's .claude/worktrees/ directory.
• Background agents now upgrade to a new version right after a Claude Code update instead of forcing a slow stale-session upgrade on next attach.
• Fixed MCP servers configured via --mcp-config or .mcp.json ignoring a per-server request_timeout_ms, which had been timing out long-running tool calls at the default 60 seconds.
• Fixed CLAUDE_CODE_EXTRA_BODY being silently ignored by background workers (claude agents / --bg), and fixed OAuth MCP servers requiring manual re-authentication after a single failed token refresh.

OpenCode Ships Three Builds in a Row: v1.17.16 → v1.17.18

OpenCode pushed three point releases on July 9 alone, moving past v1.17.15 (July 7):

• v1.17.16 exposed reasoning-effort variants for Grok models and improved xAI prompt caching and PDF support in Responses models.
• v1.17.17 shipped desktop-side work: a redesigned revert dock, a v2 free-model selector for faster multi-provider access, and a session-specific review panel mode.
• v1.17.18 fixed crashes and bad pricing data when GitHub Copilot returns models with a zero billing batch size, and added specialized system-prompt handling for Meta's Muse Spark model.

OpenAI's Codex CLI Adds a "Writes" Approval Mode

Codex CLI shipped v0.144.0 on July 9 at 16:47 UTC, followed by a same-day patch, v0.144.1, at 23:02 UTC:

• A new writes app-approval mode allows declared read-only actions to run automatically while still prompting for anything that writes to disk.
• Usage-limit reset credits now show their type and expiration, and let you choose which credit to redeem.
• MCP tools can now request interactive authentication without an experimental opt-in flag.
• Amazon Bedrock model names now identify their GPT-5.6 family and variant (Sol, Terra, Luna), first added in v0.143.0 alongside system-proxy support for macOS and Windows.
• The v0.144.1 patch fixed standalone install failures tied to GitHub metadata and stopped macOS package installs from exposing the code-mode host.

Also Worth Knowing

Cursor is holding at v3.10 (June 30) with team MCP marketplace distribution — no new release today, though its iOS beta and reported SpaceX acquisition remain the bigger story arcs this quarter. GitHub Copilot's vision capabilities reached general availability on July 4, and Kimi K2.7 Code became the first open-weight model selectable in the Copilot model picker for Business and Enterprise plans.
