Cursor CLI vs VS Code CLI: 13 Steps, 50 Min [2026]

Two tools carry the label CLI in the Cursor vs VS Code debate, and they do very different jobs. The code command opens files, manages extensions and starts tunnels. Cursor’s terminal agent reads your repository, plans edits and answers prompts without ever opening a window. VS Code still dominates daily use, since the 2025 Stack Overflow developer survey found 75.9% of respondents using it regularly against 17.9% for Cursor. Yet the CLI side keeps growing, and Cursor’s agent reportedly runs headless in scripts and CI.

This tutorial runs 13 steps and takes about 50 minutes. You will check both command lines on one machine, diff their extension lists, wire either editor into Git, run the Cursor agent headless, and gate pull requests in CI. Everything ships as a five-file kit you can copy into a repo. If you are still deciding whether to switch editors at all, read our guide to migrating from VS Code to Cursor first and come back here for the terminal side.

One caution before we start. Cursor moves fast, and the headless flags in this guide come from the vendor’s documentation and third-party write-ups rather than from a stable spec. I tested the shell scripts and the parser against stub binaries, because I cannot run your credentials. Wherever a flag comes from vendor docs, the step tells you to confirm it with --help before you rely on it. If you read our benchmark of Cursor CLI’s diff versus rewrite edits, think of this article as the plumbing around that test.

Cursor CLI vs VS Code CLI: Two Different Jobs

The first trap is the word itself. The VS Code CLI is a launcher and a manager. You type code . to open a folder, code --diff a b to compare two files, or code --install-extension to add tooling. It never writes a line of your code. The Cursor CLI, in the sense most people search for, is a terminal agent that takes a prompt, inspects the repository and proposes or applies changes. Cursor’s editor also ships a cursor launcher that mirrors the code pattern, because Cursor is built on the VS Code codebase. So you really have three things to compare, and mixing them up produces bad comparisons.

On the VS Code side, the agent job belongs to a different product. Microsoft’s own documentation points toward the Agents window inside the editor and toward GitHub Copilot CLI for terminal work, and the material I reviewed describes Copilot CLI as the official headless agent for that ecosystem. The code command has no equivalent of a headless coding agent. That gap is the real finding in any Cursor CLI vs VS Code CLI comparison, and the table below makes it concrete.

Job	VS Code code command	Cursor cursor launcher and terminal agent
Open files and folders	Yes, code . and code --goto file:line	Yes, the launcher follows the same pattern
List and install extensions	Yes, documented flags	Inherited from the shared codebase, confirm with cursor --help
Compare two files	Yes, code --diff a b	Inherited from the shared codebase, confirm with cursor --help
Act as a Git editor	Yes, with --wait	Yes in practice, same flag, confirm on your build
Run a coding agent with no window	No, launcher only	Yes, the terminal agent supports headless runs
Use in scripts and CI	Yes, for extension and file tasks	Yes, including unattended agent runs
Needs an account and usage allowance	No for the launcher	Yes for the agent, billed through the Cursor plan

Read the third column with care. The vendor material I found does not document extension or diff commands for the Cursor launcher, so I mark them as inherited rather than confirmed. Step 3 gives you a one-minute test that settles the question on your own build.

A quick rule of thumb helps when a teammate asks which command to reach for. Use this list as a starting point and adjust it to your own stack.

• Reach for code when the task is opening a file, managing extensions or comparing two files in a shell script.
• Reach for cursor when your team has standardized on Cursor and you want the same launcher behavior in Git hooks and onboarding scripts.
• Reach for the Cursor terminal agent when you want a repository-aware answer or a review with no window, on a laptop, a server or a CI runner.
• Reach for GitHub Copilot CLI when your organization pays for Copilot and wants the terminal agent that belongs to the VS Code ecosystem.
• Reach for neither when a plain grep, git log or linter already answers the question, since an agent run costs credit and time.

Prerequisites and Versions

You need a machine where both editors are installed and a repository you can experiment on. The shell scripts target Bash, so Linux, macOS and WSL all work. Native Windows PowerShell users should run the kit inside WSL. Budget 50 minutes if both editors are already installed, or about 75 if you are installing from scratch.

Requirement	Version used or needed	Why it matters
Bash	Not listed	The scripts use [[ ]], here-docs and PIPESTATUS
Git	Not listed	review-diff.sh uses the three-dot diff against a base branch
Python	Not listed	parse_agent_output.py uses only the standard library
VS Code	Any current stable build with code on PATH	Source of the baseline extension list
Cursor desktop	Any current build with cursor on PATH	Target of the extension sync
Cursor terminal agent	Latest installer	Runs the headless review in Steps 9 to 13
Cursor account	A plan with agent access, or an API key for CI	Headless runs draw on your usage allowance
GitHub repository	Actions enabled, ubuntu-latest runner	Hosts the pull request gate in Step 12

On versions, Cursor’s release notes reportedly list desktop build v2026.10.22 as the newest at the time of writing, and a separate CLI entry for build 2026.10.08 that added plan and usage visibility plus prepaid-credit balances. Treat both as single-source reports and check what your own --version prints. On the Microsoft side, the 1.143 line was reportedly announced on October 21, with 1.144 in its release endgame. None of the commands below depend on those exact numbers.

Create a scratch repository for the exercise. Any small project works, and a fresh one keeps the headless agent from reading anything sensitive.

mkdir cli-parity-kit && cd cli-parity-kit
git init -b main
mkdir -p scripts .github/workflows .cli-parity
printf '.cli-parity/\n' > .gitignore

What Changed in October 2026 and Why It Matters for the CLI

Three October events shape how you should use the Cursor CLI today. First, Cursor and X announced The X Subscription on October 12, which reportedly folds Cursor, Grok and X Premium into one set of tiers with a shared weekly usage pool. Reported prices run from $0 for Free to $8 for Plus, $30 for Premium, $100 for Super and $200 for Ultra, though I could not confirm them on an official pricing page, so check cursor.com/pricing before you budget. Second, third-party models such as Claude and GPT stay available but bill at API list prices from prepaid credit instead of the plan allowance. That matters for headless runs, because a CI job that picks a third-party model spends real credit on every pull request.

Third, Cursor released its Agent SDK. The announcement describes a way to define an agent as a folder of code, test it with evals and deploy it to Cursor or your own infrastructure, with npx @cursor/agent-sdk init ./my-bot as the starting command. Existing Cursor-plan users keep their included third-party usage until they switch plans, and the previous Ultra plan closed to new sign-ups on October 12, 2026.

The VS Code side moved too

Microsoft published a modernized UI preview on October 15, with Dark 2026 and Light 2026 themes and a shared design system for the editor and the Agents window. The Agents window has been available in Stable as a preview during 2026, and Microsoft’s March post on making agents practical explains the direction. Reports also say the Agent Host, introduced on August 26, separates the agent harness from any single editor window, and that VS Code can list sessions started outside the editor by Copilot CLI, Claude Code and Codex. For a wider view of how the three agent products compare on price and capability, see our breakdown of GitHub Copilot, Cursor and Claude Code.

The practical takeaway: both ecosystems now want you to run agents outside the editor window. That makes the CLI layer, and the glue scripts around it, more valuable than they were a year ago.

Phase 1: Install and Verify Both CLIs (Steps 1-3)

Step 1: Put code and cursor on your PATH

Open each editor, press the Command Palette shortcut, and search for Shell Command. VS Code offers an action to install the code command in PATH, and Cursor offers the matching action for cursor. Linux packages and the Windows installers usually register the commands for you, while macOS needs the manual step. Open a fresh terminal afterwards, because an existing shell will not see the change.

command -v code
command -v cursor
code --version
cursor --version

The code --version output prints three lines: the version, the commit ID and the architecture. If cursor --version prints the same three-line shape, you have confirmed the launcher mirrors the VS Code CLI. If either command is missing, jump to the troubleshooting table.

Step 2: Install the Cursor terminal agent

The terminal agent installs separately from the desktop app. Cursor publishes an install one-liner on its CLI page. Do not paste a pipe-to-shell line you have not read. Download the script, open it, then run it. Cursor’s documentation has called the executable cursor-agent, while newer material uses agent, so the kit lets you override the name with an environment variable.

curl -fsSL https://cursor.com/install -o /tmp/cursor-install.sh
less /tmp/cursor-install.sh
bash /tmp/cursor-install.sh

command -v agent || command -v cursor-agent
agent --version

Sign in with the flow the installer or the first run prompts for. For CI you will use an API key instead, and the CLI documentation names the exact environment variable. My workflow file uses CURSOR_API_KEY, so confirm that name in the authentication section of the docs before you commit the secret.

Step 3: Run the CLI doctor

The doctor script probes every binary the rest of the tutorial touches and prints the first lines of each version output. Five probes cover the editor launchers, both possible agent names, and GitHub Copilot CLI for comparison.

#!/usr/bin/env bash
# Report which editor and agent binaries are on PATH and what version each prints.
set -u

probe() {
  local name="$1"; shift
  if command -v "$name" >/dev/null 2>&1; then
    printf '%-14s %s\n' "$name" "$(command -v "$name")"
    "$name" "$@" 2>&1 | head -n 3 | sed 's/^/               /'
  else
    printf '%-14s MISSING\n' "$name"
  fi
}

probe code --version
probe cursor --version
probe agent --version
probe cursor-agent --version
probe copilot --version

The output below comes from the kit’s own test harness, where stub binaries stand in for the real tools, so the version strings are placeholders. Your machine will print real versions. What matters is the shape: a path for each found binary and the word MISSING for the rest.

$ bash scripts/cli-doctor.sh
code           /tmp/stubs/code
               1.143.1
               abc123
               x64
cursor         /tmp/stubs/cursor
               cursor-stub 0.0.1
agent          /tmp/stubs/agent
               agent-stub 0.0.1
cursor-agent   MISSING
copilot        MISSING

Now run the one-minute test promised earlier. Execute cursor --help and look for --list-extensions, --install-extension, --diff, --goto and --wait. If all five appear, the extension and Git steps work as written. If one is missing, replace it with the closest option your help output lists and continue.

Phase 2: Compare Extensions From the Terminal (Steps 4-6)

Step 4: Export both extension lists

Extensions are the biggest day-one gap between the editors, and the terminal makes the gap measurable. The --list-extensions flag prints one identifier per line, and --show-versions appends the version. Export both lists with versions for the record, then strip the versions for the diff.

code --list-extensions --show-versions   > .cli-parity/code-versions.txt
cursor --list-extensions --show-versions > .cli-parity/cursor-versions.txt
wc -l .cli-parity/*-versions.txt

Extension identifiers are case-insensitive in practice but not in output, since one editor may print GitHub.copilot where the other prints github.copilot. The next script lowercases everything before comparing, which avoids false mismatches.

Step 5: Diff the lists

The diff script writes four files: everything in VS Code, everything in Cursor, the intersection, and the two one-sided differences. It uses comm, which needs sorted input, and sort -u handles that.

#!/usr/bin/env bash
# Compare installed extensions between VS Code and Cursor.
set -euo pipefail

OUT_DIR="${1:-.cli-parity}"
mkdir -p "$OUT_DIR"

code --list-extensions | tr 'A-Z' 'a-z' | sort -u > "$OUT_DIR/code.txt"
cursor --list-extensions | tr 'A-Z' 'a-z' | sort -u > "$OUT_DIR/cursor.txt"

comm -23 "$OUT_DIR/code.txt" "$OUT_DIR/cursor.txt" > "$OUT_DIR/only-code.txt"
comm -13 "$OUT_DIR/code.txt" "$OUT_DIR/cursor.txt" > "$OUT_DIR/only-cursor.txt"
comm -12 "$OUT_DIR/code.txt" "$OUT_DIR/cursor.txt" > "$OUT_DIR/both.txt"

printf 'VS Code: %s   Cursor: %s   shared: %s\n' \
  "$(wc -l < "$OUT_DIR/code.txt")" \
  "$(wc -l < "$OUT_DIR/cursor.txt")" \
  "$(wc -l < "$OUT_DIR/both.txt")"

echo "== only in VS Code (candidates to install in Cursor)"
cat "$OUT_DIR/only-code.txt"
echo "== only in Cursor"
cat "$OUT_DIR/only-cursor.txt"

$ bash scripts/ext-diff.sh
VS Code: 6   Cursor: 3   shared: 2
== only in VS Code (candidates to install in Cursor)
eamodio.gitlens
github.copilot
ms-python.python
ms-vscode-remote.remote-ssh
== only in Cursor
anysphere.cursorpyright

That sample is synthetic, but the pattern is real. Cursor-only entries are often its own bundled language tooling. VS Code-only entries split into extensions that exist in Cursor’s registry, extensions that do not, and Microsoft-owned extensions that refuse to run outside VS Code. Our extension parity audit goes through which popular extensions fall into each bucket.

Step 6: Sync with a dry run first

The sync script reads only-code.txt and prints what it would install. It skips three families that are tied to VS Code by licensing or product design: GitHub Copilot, Microsoft’s Remote extensions and Live Share. Pass --apply to install for real. Failures land in sync-failed.txt so you can chase them manually.

#!/usr/bin/env bash
# Install VS Code-only extensions into Cursor. Dry run unless --apply is passed.
set -euo pipefail

OUT_DIR=".cli-parity"
LIST="$OUT_DIR/only-code.txt"
SKIP_RE='^(github\.copilot|ms-vscode-remote\.|ms-vsliveshare\.)'
APPLY=0
[ "${1:-}" = "--apply" ] && APPLY=1

[ -f "$LIST" ] || { echo "Run scripts/ext-diff.sh first."; exit 1; }

: > "$OUT_DIR/sync-failed.txt"
while IFS= read -r ext; do
  [ -z "$ext" ] && continue
  if [[ "$ext" =~ $SKIP_RE ]]; then
    echo "skip     $ext (known to be tied to VS Code)"
    continue
  fi
  if [ "$APPLY" -eq 1 ]; then
    if cursor --install-extension "$ext" >/dev/null 2>&1; then
      echo "installed $ext"
    else
      echo "FAILED   $ext"
      echo "$ext" >> "$OUT_DIR/sync-failed.txt"
    fi
  else
    echo "would install $ext"
  fi
done < "$LIST"

$ bash scripts/ext-sync.sh
would install eamodio.gitlens
skip     github.copilot (known to be tied to VS Code)
would install ms-python.python
skip     ms-vscode-remote.remote-ssh (known to be tied to VS Code)

$ bash scripts/ext-sync.sh --apply
FAILED   eamodio.gitlens
skip     github.copilot (known to be tied to VS Code)
installed ms-python.python
skip     ms-vscode-remote.remote-ssh (known to be tied to VS Code)

A FAILED line almost always means the extension identifier is missing from the registry Cursor reads, not that your command was wrong. Download the VSIX by hand or look for an Open VSX equivalent. If you want the manual route spelled out, our walkthrough on installing VS Code extensions in Cursor covers the VSIX path step by step.

Phase 3: Use Either Editor From Git and Scripts (Steps 7-8)

Step 7: Set the editor and diff tool in Git

Both launchers accept --wait, which blocks the terminal until you close the file. That is exactly what Git needs when it opens a commit message. The same pattern works for git difftool through the --diff flag. These four commands point Git at Cursor, and swapping cursor for code points it back.

git config --global core.editor "cursor --wait"
git config --global diff.tool cursor
git config --global difftool.cursor.cmd 'cursor --wait --diff "$LOCAL" "$REMOTE"'
git config --global difftool.prompt false

Test it with git commit on an empty change and with git difftool HEAD~1. If the editor window opens and the terminal waits, you are set. If the terminal returns instantly, the launcher handed the file to an already running window. Add --new-window to the command, or close the other window first.

Step 8: Build one switch for both editors

Teams that run both editors need one place to decide which one a script uses. A tiny shell function keyed to an environment variable does the job, and it keeps your dotfiles free of hard-coded paths. The flag table below lists the documented VS Code options the function relies on.

# ~/.bashrc or ~/.zshrc
export EDITOR_BIN="${EDITOR_BIN:-code}"

edit()  { "$EDITOR_BIN" --goto "$1"; }
ediff() { "$EDITOR_BIN" --wait --diff "$1" "$2"; }

# switch for one shell session
#   EDITOR_BIN=cursor edit src/app.py:120:5

Flag	What it does	Used in this kit
-g or --goto	Opens file:line:column at that position	Step 8 edit function
-d or --diff	Compares two files side by side	Steps 7 and 8
-w or --wait	Blocks until the file is closed	Git editor and difftool
-n or --new-window	Forces a new window	Troubleshooting
-r or --reuse-window	Reuses the last active window	Optional
--list-extensions	Prints installed extension IDs	Steps 4 and 5
--show-versions	Appends versions to the list	Step 4
--install-extension	Installs an extension by ID or VSIX path	Step 6
--disable-extensions	Starts with every extension off	Troubleshooting
--version	Prints version, commit and architecture	Steps 1 and 3

Remember that the CLI changes none of your editor settings. Keybindings, profiles and themes travel through each editor’s own sync feature, and our guide to settings sync between Cursor and VS Code covers that half of the move.

Phase 4: Run the Cursor Agent Headless (Steps 9-10)

Step 9: Make a first read-only run

Headless mode, also called print mode, runs one prompt, prints the answer and exits. Reports describe -p or --print as the switch, with --output-format accepting text, JSON or stream-JSON, and --resume and --continue for picking up earlier sessions. A --trust flag also appears in the reports, and it exists to skip the interactive prompt that asks whether you trust the workspace. Run the cheapest possible test first, with a prompt that cannot change a file.

agent --help | head -40

agent -p "Explain what scripts/ext-diff.sh does in three sentences. Do not edit files." 

Check three things in the result. The command must exit on its own, with no waiting for a keypress. The answer must mention the actual script, which proves the agent read the working directory. And nothing in git status may have changed. If any of those fail, stop here and read the troubleshooting table.

Two more checks belong in this step if you rely on shared configuration. Ask the agent which rule files it followed, because headless runs do not always load the same context as the desktop app. Our guide to shared AI rules across both editors shows how to structure the files so either tool finds them. And if your workflow needs tools beyond file access, confirm that your MCP servers load in headless mode, since the config that works in the editor may need a different path or trust approval in a terminal session.

Step 10: Capture the raw stream and read it

Never write a parser against output you have not seen. Run the agent in stream-JSON mode, save the raw output, and inspect the shapes. Each line should be one JSON object, but the keys vary by event type, and the vendor does not promise they stay stable.

agent -p --output-format stream-json \
  "List the files in scripts/ and say what each one does." \
  | tee .cli-parity/raw.jsonl | head -n 5

jq -c '{type, subtype}' .cli-parity/raw.jsonl | sort | uniq -c

The jq line counts how many events of each type came back. You will usually see a start event, several message events, and a final result event. Note which keys hold the human-readable text. My parser searches for the keys result, text and content anywhere in the object, which covers the common layouts, but if your build nests the answer under a different key, add it to TEXT_KEYS in the parser.

Also record the exit code of the run. A nonzero exit on an auth failure or a rate limit is what lets CI fail loudly instead of reporting a blank review as a pass.

Phase 5: Gate Pull Requests in CI (Steps 11-13)

Step 11: Script the review

The review script builds a diff against the base branch, truncates it if it exceeds a size cap, wraps it in a strict prompt and hands it to the agent. The prompt does three things on purpose. It forbids edits and commands, it asks for file and line references, and it demands a final line reading VERDICT: PASS or VERDICT: BLOCK, which gives the parser something exact to match.

#!/usr/bin/env bash
# Ask a headless agent to review the branch diff. Output is raw JSON lines.
set -euo pipefail

BASE="${1:-origin/main}"
AGENT_BIN="${AGENT_BIN:-agent}"
OUT="${OUT:-.cli-parity/review.jsonl}"
MAX_CHARS="${MAX_CHARS:-60000}"

mkdir -p "$(dirname "$OUT")"

DIFF="$(git diff --unified=3 "$BASE"...HEAD)"
if [ -z "$DIFF" ]; then
  echo "No diff against $BASE, nothing to review."
  : > "$OUT"
  exit 0
fi
if [ "${#DIFF}" -gt "$MAX_CHARS" ]; then
  echo "Diff is ${#DIFF} chars, truncating to $MAX_CHARS." >&2
  DIFF="${DIFF:0:$MAX_CHARS}"
fi

read -r -d '' PROMPT <<EOF || true
You are reviewing a pull request. Do not edit files or run commands.
List concrete bugs, security problems and missing tests, each with file and line.
Skip style nits. Finish with exactly one line: VERDICT: PASS or VERDICT: BLOCK.

DIFF:
$DIFF
EOF

"$AGENT_BIN" -p --output-format stream-json "$PROMPT" > "$OUT"
echo "Wrote $OUT ($(wc -l < "$OUT") lines)"

Truncation is blunt. A 60,000-character cap keeps the argument list well under Linux limits and keeps token spend predictable, but it can cut a hunk in half. For large pull requests, split the diff per file and run the agent once per file, or raise MAX_CHARS and accept the extra cost.

Step 12: Parse the stream into a verdict

The parser walks every line, ignores anything that is not valid JSON, gathers text from the known keys and looks for the last verdict marker. It returns exit code 0 for PASS, 1 for BLOCK and 2 when no verdict appears. Treating a missing verdict as a failure is the safe default, because an agent that crashed halfway should never wave a pull request through.

#!/usr/bin/env python3
"""Turn a JSON-lines agent log into Markdown and a CI exit code.

Exit codes: 0 = PASS, 1 = BLOCK, 2 = no verdict found.
"""
import json
import re
import sys
from pathlib import Path

TEXT_KEYS = ("result", "text", "content")
VERDICT_RE = re.compile(r"VERDICT:\s*(PASS|BLOCK)", re.IGNORECASE)


def collect_text(node, out):
    if isinstance(node, dict):
        for key, value in node.items():
            if key in TEXT_KEYS and isinstance(value, str):
                out.append(value)
            else:
                collect_text(value, out)
    elif isinstance(node, list):
        for item in node:
            collect_text(item, out)


def main(path):
    chunks, bad_lines = [], 0
    for line in Path(path).read_text(encoding="utf-8").splitlines():
        line = line.strip()
        if not line:
            continue
        try:
            collect_text(json.loads(line), chunks)
        except json.JSONDecodeError:
            bad_lines += 1

    text = "\n".join(chunks).strip()
    verdicts = VERDICT_RE.findall(text)
    verdict = verdicts[-1].upper() if verdicts else None

    print("## Agent review\n")
    print(text if text else "_The agent returned no text._")
    print(f"\n---\nverdict: {verdict or 'none'} | unparsed lines: {bad_lines}")

    if verdict == "PASS":
        return 0
    if verdict == "BLOCK":
        return 1
    return 2


if __name__ == "__main__":
    if len(sys.argv) != 2:
        sys.exit("usage: parse_agent_output.py review.jsonl")
    sys.exit(main(sys.argv[1]))

Here is the harness run against a throwaway repository with a deliberately bad SQL string. The stub agent emits four lines, one of them not JSON, to prove the parser survives noise.

$ bash scripts/review-diff.sh origin/main
Wrote .cli-parity/review.jsonl (4 lines)

$ python3 scripts/parse_agent_output.py .cli-parity/review.jsonl
## Agent review

1. src/db.py:42 builds SQL with an f-string, which allows injection.
VERDICT: BLOCK

---
verdict: BLOCK | unparsed lines: 1
$ echo $?
1

Step 13: Wire it into GitHub Actions

The workflow checks out the full history, installs the agent, runs the review and publishes the Markdown to the job summary. It skips pull requests from forks, because GitHub withholds secrets from them and the job would fail for the wrong reason. It also grants the token read-only repository access, which is all this job needs.

name: agent-review

on:
  pull_request:
    branches: [main]

permissions:
  contents: read

jobs:
  review:
    runs-on: ubuntu-latest
    timeout-minutes: 15
    # Fork PRs get no secrets, so skip them instead of failing.
    if: github.event.pull_request.head.repo.full_name == github.repository
    steps:
      - uses: actions/checkout@v4
        with:
          fetch-depth: 0

      - name: Install Cursor CLI
        run: |
          # Verify this line against cursor.com/cli before you trust it.
          curl https://cursor.com/install -fsS | bash
          echo "$HOME/.local/bin" >> "$GITHUB_PATH"

      - name: Review the diff
        env:
          CURSOR_API_KEY: ${{ secrets.CURSOR_API_KEY }}
        run: bash scripts/review-diff.sh "origin/${{ github.base_ref }}"

      - name: Summarize and gate
        run: |
          python3 scripts/parse_agent_output.py .cli-parity/review.jsonl | tee -a "$GITHUB_STEP_SUMMARY"
          exit "${PIPESTATUS[0]}"

      - uses: actions/upload-artifact@v4
        if: always()
        with:
          name: agent-review
          path: .cli-parity/

Add the API key under Settings, Secrets and variables, Actions, using the same name as in the workflow. Then open a pull request that contains one obviously bad change and watch the job. A failing check on that pull request proves the gate works. A passing check on a clean pull request proves it does not block good work. Run both before you make the check required in branch protection.

Cost needs a ceiling. Cursor reportedly offers spending caps on prepaid top-ups, and GitHub states that one AI credit equals $0.01 for its own agent products, which gives you a mental model for budgeting either path. Set a cap, pick the cheapest model that catches your bug class, and log token or credit use per run so a runaway prompt shows up in a dashboard rather than on an invoice.

Run the Whole Kit End to End

With every file in place, the repository looks like the tree below. Run the scripts in order on a local machine first. The whole sequence takes about two minutes when the extension lists are short, plus whatever the agent run needs.

# make a small change, commit it
bash scripts/review-diff.sh origin/main
python3 scripts/parse_agent_output.py .cli-parity/review.jsonl

Read the outputs in that order for a reason. The doctor tells you which binaries exist, the diff tells you how far apart the editors are, and the dry-run sync tells you how much work the gap represents. Only after those three look sensible does it make sense to spend agent credit on a review. If the doctor shows no agent binary, stop and fix the install, because every later step will fail in a confusing way.

Use this checklist to confirm the project works before you push it to a team repository.

• cli-doctor.sh finds code, cursor and one agent binary.
• ext-diff.sh writes four text files into .cli-parity/ and prints a count line.
• ext-sync.sh in dry-run mode changes nothing on disk.
• A review of an empty diff exits 0 with a short message.
• A review of a bad diff exits 1 and prints the findings.
• A run with the agent binary renamed exits nonzero, not zero.

Common Pitfalls

Seven mistakes cause most of the failures in a setup like this one, and each is cheap to avoid.

Comparing the wrong things. Putting code next to agent in a benchmark tells you nothing, since one opens windows and the other edits code. Compare code with cursor for launcher behavior, and compare the Cursor agent with Copilot CLI or another terminal agent for coding behavior.

Running an unread install script. A pipe from curl into bash executes whatever the server returns at that moment. Download first, read it, then run it, as Step 2 does. Pin the installer in CI by checking in a hash of the script you reviewed.

Giving the CI agent write access. A review job needs to read a diff and print text. If you pass flags that allow file edits or shell commands, a prompt injection hidden in a pull request can turn into code execution on your runner. Keep review jobs read-only, and read the permissions section of the CLI docs before adding any force or auto-approve option.

Using pull_request_target with agent steps. That trigger runs with secrets against code from outside your org. Pairing it with an agent that reads attacker-controlled diffs is the classic way to leak a key. Stay on pull_request, skip forks, and let a maintainer re-run the job manually for outside contributions.

Trusting the output schema. The reports list text, JSON and stream-JSON formats, and nothing says the event keys stay constant between builds. Pin the CLI version in CI, keep the raw log as an artifact, and make the parser fail closed, as ours does with exit code 2.

Letting line endings pollute the diff. A Windows contributor with autocrlf set can turn a three-line change into a 3,000-line rewrite, which burns tokens and buries the real issue. Normalize with a .gitattributes file before the review step, and our guide to gitattributes for AI diffs shows the exact rules.

Assuming desktop sign-in covers the terminal. An independent review of the tool cites a forum report that some desktop plugins need a separate CLI sign-in, and that certain plugins can fail when the CLI does not send the expected authentication header. Treat the terminal agent as its own client, log in separately, and test any plugin-dependent workflow in the terminal before you promise it to the team.

Troubleshooting: 10 Problems and Fixes

Symptom	Likely cause	Fix
cursor: command not found	Shell command never installed, or shell not restarted	Run the Shell Command action from the Command Palette, then open a new terminal
code opens Cursor, or the reverse	Another install rewrote the PATH entry	Run command -v code and type -a code, then fix PATH order
--list-extensions prints nothing in CI	No editor installed on the runner	Extension scripts are for dev machines, so skip them in the CI job
Extension install fails with not found	ID missing from the registry Cursor reads	Download the VSIX and pass its path to --install-extension
Install hangs behind a proxy	Registry request blocked or slow	Set HTTPS_PROXY, or install the VSIX file offline
git commit returns instantly	Launcher handed the file to a running window	Add --new-window or close the other window
Agent waits forever in CI	Interactive trust or approval prompt	Check --help for the trust option, and keep prompts read-only
401 or login error in Actions	Secret missing, misnamed or unavailable to forks	Match the secret name to the docs, and skip fork pull requests
Parser prints no text, exits 2	Output keys differ from TEXT_KEYS	Inspect the raw log with jq and add the real key
Review cuts off mid-diff	MAX_CHARS cap hit	Split by file or raise the cap and monitor cost

If your problem involves WSL paths, SSH hosts or dev containers, the fix usually lives in the editor’s remote layer, not the CLI. Our comparison of remote development in VS Code and Cursor covers those setups in detail.

For any issue the table does not cover, reduce it to the smallest repro. Run the single command in a clean shell, then rerun with --disable-extensions for editor commands or with a one-line prompt for the agent. Most failures disappear in the smaller case and point straight to the cause.

Advanced Tips

Graduate to the Agent SDK when scripts get long

A shell script wrapped around one prompt works until you need retries, tool limits or evaluation. That is the point where the Agent SDK earns its place. The October 20 announcement describes a project you create with npx @cursor/agent-sdk init ./my-bot, run locally with agent-sdk dev, test with agent-sdk eval locally or in CI, and ship with agent-sdk deploy. Reports also say the TypeScript SDK supports unattended runs with a chosen model, disabled tools, local working directories and sandboxing, which is more control than a flag on a one-liner gives you.

Pin everything the gate depends on

Pin the CLI version, pin the model, and pin the prompt in a file under version control. When a review result changes, you want to know which of the three moved. Keep the prompt in prompts/review.md, load it in review-diff.sh, and review changes to it like code. Add a nightly job that runs the same diff against the gate and alerts you if the verdict flips without a code change.

Measure before you trust

Build a small test set of ten diffs: five with known bugs and five clean. Run the gate against them whenever you change the model, the prompt or the CLI version. Record how many bugs it catches and how many clean diffs it blocks. A gate that blocks one clean pull request in five will lose the team’s trust within a week.

Keep the kit editor-agnostic

The EDITOR_BIN switch from Step 8 generalizes. Use it in your Makefile and in onboarding scripts, so a teammate who prefers VS Code gets the same results as one who prefers Cursor. Pair the review gate with a human reviewer, not instead of one. The agent catches mechanical mistakes, and the human decides whether the design makes sense.

Run a lighter check before every push

CI is the right place for the full review, but waiting four minutes for a red check is slow. A pre-push hook can run the same script locally against only the commits you are about to share. Keep it opt-in with an environment variable, so a developer without agent access can still push.

#!/usr/bin/env bash
# .git/hooks/pre-push  (chmod +x)
[ "${AGENT_PREPUSH:-0}" = "1" ] || exit 0

bash scripts/review-diff.sh origin/main || exit 1
python3 scripts/parse_agent_output.py .cli-parity/review.jsonl >/dev/null
status=$?
[ "$status" -eq 1 ] && { echo "Agent review says BLOCK. See .cli-parity/review.jsonl"; exit 1; }
exit 0

The hook blocks only on an explicit BLOCK verdict. It lets a missing verdict through locally, because a flaky network should not stop a developer from pushing. CI keeps the stricter rule.

Log every run

Append one line per run to a CSV: timestamp, branch, model, diff size in characters, verdict and exit code. After two weeks you can answer the questions that matter. How often does the gate block, how often do humans overrule it, and what does a typical run cost. Without that log, every conversation about the gate turns into opinion.

FAQ

Is the Cursor CLI the same as the cursor command?

No. The cursor command is a launcher that opens files and folders in the desktop editor. The Cursor CLI that most searches mean is the terminal agent, installed separately, which takes prompts and works on your repository without a window.

Does VS Code have a headless coding agent in its CLI?

The code command does not. Microsoft’s agent tooling lives in the Agents window and in GitHub Copilot CLI, which is a separate program. If you need unattended agent runs in a VS Code-centered workflow, Copilot CLI is the closest match.

Can I run VS Code and Cursor on the same machine?

Yes. They keep separate settings, separate extension folders and separate user data. The only conflict is the PATH entry for code if both installers try to claim it, and the EDITOR_BIN switch in Step 8 sidesteps that.

Will extensions I install from the terminal show up in the desktop app?

Yes, for the same editor. Each editor reads its own extensions folder, so installing with code affects VS Code only, and installing with cursor affects Cursor only. That is why the kit compares the two lists and syncs one direction.

Is it safe to run an AI agent on every pull request?

It is safe when the job is read-only, runs only on branches from your own repository, uses a scoped secret and has a spending cap. It is risky when the agent can write files or run commands on code written by outsiders.

How do I update the terminal agent?

Rerun the installer you inspected in Step 2, or follow the update instructions on Cursor’s CLI page. In CI, pin the installer and bump it deliberately, then rerun your ten-diff test set before merging the bump.

Do I need a paid plan for headless runs?

Headless runs use your Cursor account and its usage allowance, so check the pricing page for what your plan includes today. Third-party models bill separately, and a cap on spending protects you from surprises.
