Cursor Common Errors

What it does

When your agent uses it

• Cursor not working
• Tasks that involve Authentication

Example prompts

• “cursor error”
• “cursor not working”
• “cursor issue”
• “/cursor-common-errors”

Requirements

• Compatibility (from SKILL.md): Designed for Claude Code
• Pre-approved tools (allowed-tools): Read, Write, Edit, Bash(cmd:*)

Workflow steps

4 steps, taken from the first numbered list in SKILL.md.

1. 1Reproduce the issue with extensions disabled or in a disposable profile when possible.
2. 2Capture the smallest relevant status/log evidence and try the least-destructive documented remedy.
3. 3Back up settings before clearing caches or resetting state, then validate recovery with a non-sensitive workspace.
4. 4Escalate persistent issues with a redacted reproduction instead of sharing workspace data.

What it can do on your machine

Read from SKILL.md and the folder at commit cfae287. It shows what the files ask for, not the result of running them.

• Tool permissions

  Pre-approves these tools, so the agent can use them without asking each time:

  • Read
  • Write
  • Edit
  • Bash(cmd:*)

  From allowed-tools in the SKILL.md frontmatter.

• Runs code

  Shell commands in SKILL.md call:

  • cursor
  • git

  From the folder's file list and the shell code blocks in SKILL.md.

• Network

  Hosts in commands or code, which the agent is likely to contact:

  • proxy.corp.com

  Also links to:

  • status.cursor.com
  • cursor.com
  • open-vsx.org
  • forum.cursor.com
  • github.com

  From URLs in SKILL.md, links to its own repository left out.

• Credentials

  Names no API keys, tokens, secrets or passwords.

  From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

• Compatibility

  Designed for Claude Code

  From compatibility in the SKILL.md frontmatter.

Context cost

Cursor Common Errors loads about 2.2k tokens when it runs, and up to ~2.9k if it reads all its reference files. Until then it costs about 60 tokens; SKILL.md has 881 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it

~60

When it runs · the whole SKILL.md, loaded when a task matches

~2.2k

With references · SKILL.md plus every file in references/, read only if the agent opens them

~2.9k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

Step 1: Open Process Explorer
  Cmd+Shift+P > "Developer: Open Process Explorer"
  Identify which process uses most CPU/memory

Step 2: Extension audit
  Disable extensions one-by-one to find the culprit
  Common offenders: GitLens (large repos), Prettier (on save), ESLint

Step 3: Reduce indexed scope
  Add large directories to .cursorignore

Step 4: Clear chat history
  Long chat sessions consume memory. Start new chats frequently.

Step 5: Increase memory limit
  settings.json: "files.maxMemoryForLargeFilesMB": 4096

# Start with extensions disabled
cursor --disable-extensions

# Start with GPU disabled (Linux/Windows)
cursor --disable-gpu

# Reset to defaults (nuclear option -- backs up settings first)
# macOS:
cp -r ~/Library/Application\ Support/Cursor ~/cursor-backup
rm -rf ~/Library/Application\ Support/Cursor/Cache
rm -rf ~/Library/Application\ Support/Cursor/CachedData
