Cmd-K for surgical edits, Cmd-L for chat with file context, Composer (agent mode) for multi-file work, Bugbot for PR review on push. One tool for the whole loop.
Cursor (IDE-first)
If you'd rather see the diff as you go than read a terminal log, Cursor is the answer. Cmd-K for inline edits, agent mode for multi-file changes, Bugbot reviews the PR. The editor stays the source of truth all the way through.

Agent SDK becomes generally available for defining, testing, and deploying agents
The Agent SDK allows developers to define agents as a folder of code with typed tool actions, test them with evals that check tool calls and responses, and deploy to Cursor infrastructure or anywhere else. Agents can trigger on GitHub/GitLab/Bitbucket events, Slack mentions, webhooks, or cron schedules, with full session history and multi-turn support.
Cursor released Agent SDK for defining and deploying agents as code
The Agent SDK allows developers to define agents as a folder of code with typed tools and test them with evals before deploying to Cursor or custom infrastructure. Includes CLI tools (agent-sdk init, dev, deploy, eval) and built-in templates for security reviewers, PR autofixers, and triagers. Agents receive events from GitHub, GitLab, Bitbucket, Slack, webhooks, and cron schedules.
Agent SDK released for building and deploying agents as code
New SDK allows developers to define agents as folders of code with instructions.md as the prompt, test them locally with evals, and deploy to Cursor infrastructure or custom environments. Supports GitHub, GitLab, Bitbucket, Slack, webhooks, and cron triggers.
Cursor releases Agent SDK for building and deploying custom agents
The Agent SDK lets developers define agents as code folders with instructions.md, typed tools, and channel definitions, then deploy them locally or to Cursor infrastructure. Agents can be triggered by GitHub/GitLab/Bitbucket events, Slack messages, webhooks, or schedules, with full session management, evals, and sandbox testing available.
- 1Plan in Cursor's chat panelCursor
Cmd-L. Add the ticket and the most-relevant 2 to 3 files via @-mentions. Get the plan there; you stay in the editor.
Prompt · Scope a change inside Cursor (Cmd-L)Plan a small, well-scoped PR for the change below. Don't write the code yet. Ticket / problem: """ {{paste ticket}} """ I've @-mentioned the most relevant files. Use them as the source of truth for current behavior. Output: 1. Restated problem in 2 sentences. 2. Files to touch + 1-line "why" each. 3. Smallest viable diff in 5 to 8 bullets. 4. Edge cases (3 to 5). 5. What I should NOT change. Ask 1 to 2 clarifying questions if the ticket is genuinely ambiguous. - 2Implement with ComposerCursor
Switch to agent mode (Composer). Hand it the plan + the files. Cursor proposes a multi-file diff inline; accept or reject hunks visually.
- 3Inline iterate with Cmd-KCursor
For tight edits inside one file, skip the agent — Cmd-K is faster. The editor stays in flow.
- 4Open the PRCursor
Push the branch. Bugbot posts its review on the PR automatically — same surface as a human reviewer, so teammates see the findings too.
- 5Patch findings inlineCursor
Bring the Bugbot comments back into Cursor's chat panel; Composer turns them into a patch you can review hunk-by-hunk.
On UI work, the IDE-first loop won: changes are visual, the editor is where you naturally iterate. On backend refactors that span 10+ files, the team preferred Claude Code because Composer's hunk-by-hunk acceptance got tedious. Mixed-mode users tended to keep both subscriptions active.
On a 12-file diff, accepting hunks one at a time in the editor takes longer than reading a CLI agent's summary. Pick the right surface for the size of the change.
If your team also reviews from the GitHub web UI without Cursor open, Bugbot's comments are still visible (they post to the PR), but the inline IDE features are not. Make sure the PR-level review is the source of truth, not the in-editor markers.
