Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00036 | $0.02255 |
| Opus 5 | $0.00018 | $0.01128 |
| Sonnet 5 | $0.00007 | $0.00451 |
| Haiku 4.5 | $0.00004 | $0.00226 |
Grade A, and why
cursor-tools-mastery 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 11d 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.
How it starts
The opening of the file, as written. The whole thing — 173 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Cursor 3.7 Tools Mastery
Keep durable behavior in the core rule. Use this file for current Cursor 3.7 tool-selection patterns and the Agents Window surface.
Cursor 3.7 workspace
In Cursor 3.7, agent work is centered in the Agents Window. Open it from the command palette: Cmd+Shift+P -> Agents Window on macOS (per the Cursor 3 announcement; 3.7 changelog at cursor.com/changelog). The classic three-pane editor is still available; switch between them at any time.
- Multi-workspace / multi-repo: the Agents Window can surface several workspaces at once. Name the repo or root path when handing off work, opening files, or running commands so edits land in the intended tree.
- Per-session execution environment: each agent tab picks its own environment — local working tree, isolated worktree (
/worktree), cloud sandbox, or remote SSH. State the environment in the handoff contract; it is the unit of isolation. - Per-session model picker: the model picker lives in the agent tab header (e.g.
composer-2.5,MiniMax-M3,auto). Name the model in the handoff contract. - Integrated browser: prefer the IDE's built-in browser for local UI verification when it is exposed in your session; it matches the "snapshot-first" flow in Browser Guidance below. Cursor 3.7 adds Design Mode (multi-select elements, voice input) — user selections there are ground truth for UI edits.
- Canvases: live React artifacts beside the chat for dashboards, reports, and structured analyses; load the
canvasskill before.canvas.tsxwork.
Golden Rule
For significant actions:
Check what exists
Choose the smallest correct tool
Act
Validate with the lightest useful verification
Default Tool Map
Cursor 3.7 / Composer-style agents (typical names in current desktop agents) — the session usually exposes something close to:
| Step | Tool / command | Notes |
|---|---|---|
| Read a path | Read |
Prefer over shell cat/sed |
| Search by pattern | Grep |
Ripgrep-backed; use for exact symbols and strings |
| Search by meaning | SemanticSearch |
"Where does X happen?" not exact text |
| List paths | Glob |
File discovery by pattern |
| Edit in place | StrReplace |
Surgical edits; read the file first |
| Create or replace whole file | Write |
Use when there is no stable old_string to patch |
| Remove file | Delete |
|
| Terminal | Shell |
Builds, tests, git, installs |
| Web | WebSearch, WebFetch |
|
| Ask user | AskQuestion |
|
| Track steps | TodoWrite |
|
| Delegate branch work | Task |
Subagent-style runs (types such as explore, debugger, verifier — see schema) |
| Wait for background work | Await |
Wait for a background shell, subagent, or a specific output token (e.g. Ready, Error) |
| Isolated worktree | /worktree |
Run a session in its own git worktree so concurrent edits do not collide |
| Parallel model compare | /best-of-n |
Run the same task across N models in parallel worktrees, then compare |
| MCP servers | call_mcp_tool (+ resource helpers if present) |
Read MCP tool descriptors before calling |
| Plan mode | SwitchMode |
When the product exposes a planning mode |
| Images | GenerateImage |
Only when the user asks for generated images |
| Notebooks | EditNotebook |
.ipynb cell edits |
| Lint diagnostics | ReadLints |
After substantive edits when available |
| Multimodal inputs | Read against attached image/video paths |
M3 native multimodal — treat as first-class inputs |
| Interactive artifact | Canvas (.canvas.tsx) |
Dashboards, reports, MCP tabular output — load canvas skill first |
| Context diagnostics | Context usage report canvas | 3.7 — token breakdown across prompt, tools, rules, skills |
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.

cursor-tools-mastery is a cursor rule published in the GitHub repository madebyaris/advance-minimax-m3-cursor-rules (125 stars, last pushed 2mo ago), licensed MIT. It adds 36 tokens to every session and 2,255 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
