Skill for Cursor

This is saski/arnesto's own configuration. It tells Cursor how to work on arnesto itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything arnesto configures →

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

update-cli-config scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 3d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Origin

This is a copy

91% identical to update-cli-config — 11 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

Cursor CLI Configuration

This skill explains how to view and modify Cursor CLI settings stored in ~/.cursor/cli-config.json.

Config File Location

The config file is ~/.cursor/cli-config.json.

Projects can layer overrides via .cursor/cli.json files. The CLI walks from the git root to the current working directory and merges each .cursor/cli.json it finds (deeper files take precedence). Project overrides only affect the current session; they are not written back to the home config.

How to Modify

Read ~/.cursor/cli-config.json, apply changes, and write it back. The file is standard JSON. Changes take effect after restarting the CLI.

Available Settings

permissions (required)

Tool permission rules. Each entry is a string pattern.

  • allow: string[] — patterns for allowed tool calls (e.g. "Shell(**)", "Mcp(server-name, tool-name)")
  • deny: string[] — patterns for denied tool calls

editor

  • vimMode: boolean — enable vim keybindings in the CLI input
  • defaultBehavior: "ide" | "agent" — default behavior mode

display (optional)

  • showLineNumbers: boolean (default: false) — show line numbers in code output
  • showThinkingBlocks: boolean (default: false) — show model thinking/reasoning blocks
  • showStatusIndicators: boolean (default: false) — show status indicators in the UI

channel (optional)

Release channel: "prod" | "lab" | "static"

maxMode (optional)

boolean (default: false) — enable max mode for higher-quality model responses

subagentModels (optional)

Per-subagent model settings.

  • explore: "default" | "inherit" | "disabled" or { "modelId": string, "parameters"?: [{ "id": string, "value": string }], "maxMode"?: boolean } — use Cursor's default Explore model, inherit the parent agent's model, disable the Explore subagent, or pin a specific model. When parameters is omitted, saved per-model parameter preferences apply; when maxMode is omitted, the parent conversation's max mode applies.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
