brisk

Short, fast Cursor replies. Exact code and errors. No proxy, no account. One install covers every local project.

Why

Cursor sends the whole thread back on every turn: your messages, the agent's replies, and tool results. Filler is paid twice — once when it is generated, then again on every later message.

Agents default to long prose: pleasantries, hedging, "let me look at that." That text is mostly unused. Code, errors, and file reads still have to be exact, so you cannot shrink those.

Brisk is a local skill that cuts the chat text and leaves the rest alone. No proxy, no extra model, no per-project setup.

Add it

cd ~/Desktop/brisk
node bin/brisk.mjs add

Reload Cursor (Cmd+Shift+P → Developer: Reload Window), then type /brisk in chat.

Commands

Command	What it does
add	Writes ~/.cursor/skills/brisk/SKILL.md
add --force	Overwrite if a previous copy exists
add --always	Also print a User Rule to paste for always-on
status	Check the install
remove	Delete the global skill

Always-on (optional)

The skill is available in every project. To apply it in every chat without /brisk:

1. node bin/brisk.mjs add --always
2. Paste the printed text into Cursor Settings → Rules → User Rules

Intensity

/brisk lite · /brisk full (default) · /brisk off or normal mode

This only shrinks what the agent says. It does not compress files, logs, or tool results.

Code, errors, and identifiers stay exact. The skill keeps a sentence if dropping it would change what you should do; it cuts padding. It can still mis-classify. Too thin: /brisk lite or normal mode. Details: doc/how-it-works.md.

Modes

/brisk is a skill in the Agent panel. A User Rule from --always applies in every mode.

Mode	Chat text	What stays full
Agent	Short replies, no "let me look at that"	Code, diffs, tool results, commits
Ask	Short answers	Quoted code and errors (read-only)
Plan	Short chat while researching	The plan you review (persisted, readable)

Switching modes starts a new context. Type /brisk again in that chat, or use the User Rule so you do not have to.
