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 | $0.00093 | $0.02879 |
| Opus 5.5 | $0.00037 | $0.01152 |
| Sonnet 5.5 | $0.00019 | $0.00576 |
| Haiku 4.5 | $0.00009 | $0.00288 |
Grade A, and why
macwright-patterns 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 1mo 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.

MacWright Automation Patterns
Patterns and pitfalls discovered from iterative testing of all 24 macwright tools.
Wait+Screenshot Chaining
Most action tools accept optional wait (ms) and screenshot (bool) params:
click(x: 500, y: 300, wait: 500, screenshot: true)
→ clicks, waits 500ms, returns screenshot
This collapses 3 tool calls into 1. Use it to verify actions immediately.
Tool Selection Guide
| Task | Best Tool | Notes |
|---|---|---|
| Navigate Safari | safari_url |
Never click address bar |
| Manage Safari tabs | safari_tabs |
list/new/close/select actions |
| Fill web form | fill_form |
Multi-field, dispatches input/change events, supports textarea |
| Click web element | click_element |
CSS selector → scrolls into view → click in one step |
| Click by visible text | click_text("Submit") |
No CSS selector — finds by text, picks most specific match |
| Hover over element | hover_element |
CSS selector → moves mouse over it (triggers :hover, dropdowns) |
| Get web element coords | find_element |
When you need coords without clicking |
| Find all matching elements | find_element(all: true) |
Returns array of coords + text |
| Screenshot a DOM element | screenshot_element |
Scrolls into view, captures region |
| Wait for DOM element | wait_for_element |
After navigation/AJAX |
| Scroll web page (relative) | scroll_page(y: 500) |
Focus-free, returns position |
| Scroll web page (absolute) | scroll_page(y: 0, absolute: true) |
Jump to exact position (e.g. top) |
| Scroll overflow div element | scroll_element(selector, y: 200) |
Scroll a specific DOM container |
| Scroll native app | scroll + focus_window first |
App must be frontmost |
| Type ASCII | type_text |
Direct AppleScript |
| Type emoji/Unicode | type_text |
Auto-detects, uses clipboard |
| Type with autocomplete | type_text(slowly: true) |
50ms delay per char, triggers keystroke handlers |
| Run shell command | run_shell |
Returns stdout/stderr; exit code in text, only timeout = isError |
| Process data with jq | run_shell(command: "jq ...") |
jq available at /usr/bin/jq |
| Process data with python | run_shell(command: "python3 -c ...") |
[email protected] available |
| Reload Safari page | safari_reload |
Faster than Cmd+R |
| Check what's visible | screenshot(x,y,width,height) |
Region param for focused view |
| Find app state | get_frontmost_app |
Returns bounds too |
| List all windows | list_windows |
JSON array of apps+bounds |
| Dismiss menus | press_key(key: "esc") |
Works for context menus too |
| Window positioning | resize_window |
Set exact x,y,width,height |
| Current page info | get_page_info() |
URL, title, readyState in one call |
| Discover form fields | get_form_fields() |
All inputs/selects/buttons with types/names |
| Extract all links | get_links(filter: '/blog') |
Links with text+href, filterable by URL |
| Scroll to element | scroll_to_element(selector) |
scrollIntoView with alignment |
| Focus element | focus_element(selector) |
Trigger focus event (no click) |
| Navigate forward | safari_navigate_forward |
History.forward() |
| Wait for condition | wait_for_function(expr) |
Most flexible wait — any JS expression |
| Wait for text | wait_for_text("Success") |
Page body textContent check |
| Wait for URL | wait_for_url("/dashboard") |
URL contains pattern |
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.

macwright-patterns is a skill published in the GitHub repository ruchit-p/macwright (0 stars, last pushed 2mo ago), licensed MIT. It adds 93 tokens to every session and 2,879 once invoked, about $0.0004 per session on Opus 5.5. 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 2026-08-31.
