[Codex's event triggers](/release/rel_kur0Rq7FhgPXbwq0UInqI-codex-adds-event-triggers-from-gmail-slack-and-github-for-scheduled-tasks) let scheduled tasks fire from Gmail messages (filtered by sender or subject), Slack channel activity, or GitHub pull request events — so a review request can kick off a code change without you remembering to schedule it. Meanwhile, [Cursor cloud agents](/release/rel_E2Q8CKxOXx4aBN2zEVLkd-cursor-lets-cloud-agents-start-from-scratch-without-a-repo) no longer require a connected GitHub repo: pick "Start from scratch," prompt the agent, and it works in a temporary environment you can save to a Cursor Origin repo later. That's a meaningful lowering of the barrier for one-off automations and experiments. The theme continues in [Codex CLI 0.150.0](/release/rel_mnYvqM8aEGfLQjibZtP5z-codex-cli-0-150-0-adds-task-mentions-and-interrupt-hooks), which adds task @-mentions so agents can read, create, or message other tasks from the terminal — useful for chaining multi-step workflows. The mobile counterpart, [Codex for iOS](/release/rel_utvXa1OlgFOnL_SbPuNpm-codex-for-ios-adds-task-search-reasoning-gauge-and-home-screen-shortcuts), gains task search, a reasoning-effort gauge, and Home Screen shortcuts, making remote agent management more practical. ### Tighter guardrails and spend visibility Autonomy needs guardrails, and Claude Code shipped two notable ones. [v2.1.248](/release/rel_xE6C7BoLBADqnjRyCRZ8z-claude-code-v2-1-248-adds-restricted-mode-and-fixes-prompt-cache-miss-in-long) adds `--restricted` mode, which strips out command/code execution tools and WebFetch unless explicitly named, keeps file tools inside the working directory, and refuses `bypassPermissions` — ideal for untrusted codebases or CI. [v2.1.247](/release/rel_p5ReNMN7Ra4NXtRZwmyXQ-claude-code-v2-1-247-adds-cost-optimize-command-and-hardens-plugin-marketplace) introduces `/claude-api cost-optimize` to profile and reduce API spend, plus a `SendFeedback` tool for drafting bug reports. And [v2.1.251](/release/rel_cjDMvrFyWrx0h3fPpUjHk-claude-code-v2-1-251-adds-premodelswitch-hooks-spend-limit-tracking-and-numerous) adds a spend limit bar to `/usage` and a `rate_limits.spend_limit` status field — direct visibility into runaway costs. Also worth noting: [v2.1.246](/release/rel_3kYA4VNJqb62eQIAt2I8l-claude-code-v2-1-246-fixes-credential-leak-to-third-party-gateways-and) fixes a credential leak where telemetry to Anthropic could carry a third-party gateway's API key, and [v2.1.245](/release/rel_hgR7aCiBnyAh14JBBTcWV-claude-code-v2-1-245-fixes-startup-crash-on-glibc-2-44-linux) patches a startup crash on glibc 2.44 Linux distros like Arch. ### Subagent infrastructure matures The plumbing around agents improved across the board. Grok Build's 1.0.13 auto-continues truncated responses and retries transient inference failures, while [1.0.12](/release/rel_Hb2puCOlfryrg1vZ3y-0y-grok-build-1-0-12-retries-transient-mcp-failures-and-fixes-table-cell-copying) retries flaky MCP connections and fixes table-cell copying. [Claude Code v2.1.251](/release/rel_cjDMvrFyWrx0h3fPpUjHk-claude-code-v2-1-251-adds-premodelswitch-hooks-spend-limit-tracking-and-numerous) streams live tool calls from foreground subagents to Remote Control clients — a big debugging win — and adds `PreModelSwitch`/`PostModelSwitch` hooks for intercepting model changes. [Devin's August 26 update](/release/rel_WKc5dqDWU0YIw05MQfoe5-devin-august-26-2026-update-adds-slack-improvements-and-security-section) improves Slack @mention routing and moves code scan pages under `/security` with batch remediation API routes. Codex CLI's [0.150.1](/release/rel_x8ahQ1UPYxsJvalMtK3Bk-codex-cli-0-150-1-counts-retained-images-toward-compaction-token-budget) counts retained images toward the remote compaction token budget, preventing silent context loss. The consistent thread: agents are getting more reliable under failure, more observable in flight, and more respectful of your budget. ## Releases covered ### Anthropic - [Claude Code v2.1.248 adds restricted mode and fixes prompt-cache miss in long sessions](https://releases.sh/release/rel_xE6C7BoLBADqnjRyCRZ8z-restricted-mode-added-prompt-cache-miss-in-long-sessions-fixed) - [Claude Code v2.1.247 adds cost-optimize command and hardens plugin marketplace](https://releases.sh/release/rel_p5ReNMN7Ra4NXtRZwmyXQ-cost-optimize-command-plugin-marketplace-hardening) - [Claude Code v2.1.251 adds PreModelSwitch hooks, spend limit tracking, and numerous security fixes](https://releases.sh/release/rel_cjDMvrFyWrx0h3fPpUjHk-premodelswitch-hooks-added-symlink-path-traversal-fixed) - [Claude Code v2.1.246 fixes credential leak to third-party gateways and fullscreen regressions](https://releases.sh/release/rel_3kYA4VNJqb62eQIAt2I8l-credentials-no-longer-leak-to-third-party-gateways) - [Claude Code v2.1.245 fixes startup crash on glibc 2.44 Linux](https://releases.sh/release/rel_hgR7aCiBnyAh14JBBTcWV-startup-crash-fixed-on-glibc-2-44-linux) ### Cognition - [Devin August 26, 2026 update adds Slack improvements and security section](https://releases.sh/release/rel_WKc5dqDWU0YIw05MQfoe5-slack-routing-smarter-code-scan-pages-moved) ### Cursor - [Cursor lets cloud agents start from scratch without a repo](https://releases.sh/release/rel_E2Q8CKxOXx4aBN2zEVLkd-cloud-agents-start-from-scratch-origin-repo-on-demand) ### OpenAI - [Codex adds event triggers from Gmail, Slack, and GitHub for scheduled tasks](https://releases.sh/release/rel_kur0Rq7FhgPXbwq0UInqI-scheduled-tasks-can-trigger-from-gmail-slack-github-events) - [Codex CLI 0.150.0 adds task @-mentions and Interrupt hooks](https://releases.sh/release/rel_mnYvqM8aEGfLQjibZtP5z-mention-other-tasks-interrupt-hooks-added) - [Codex for iOS adds task search, reasoning gauge, and Home Screen shortcuts](https://releases.sh/release/rel_utvXa1OlgFOnL_SbPuNpm-task-search-reasoning-gauge-and-home-screen-shortcuts-land) - [Codex CLI 0.150.1 counts retained images toward compaction token budget](https://releases.sh/release/rel_x8ahQ1UPYxsJvalMtK3Bk-remote-compaction-now-counts-retained-images-in-token-budget) ### xAI - [Grok Build 1.0.12 retries transient MCP failures and fixes table cell copying](https://releases.sh/release/rel_Hb2puCOlfryrg1vZ3y-0y-mcp-failures-retried-table-cells-copy-cleanly)
