Extract text from images and screenshots locally with mac-ocr, Apple's on-device Vision engine. Use when bulk-triaging screenshots or images (sorting Desktop or Downloads clutter), reading text out of a PNG or JPG, or any time image text needs extracting without spending vision tokens.

Capture and persist browser screenshots or GIFs for visual review of a web UI. Use when verifying a UI change visually, reviewing a page's design or layout, recording a multi-step interaction (dropdown, hover, form flow), toggling dark mode for a comparison shot, or when a screenshot needs to be written to disk rather than only shown inline.
Run and troubleshoot copier updates in a project generated from one of the user's templates, and maintain the templates themselves. Use when a task mentions copier, copier update, .copier-answers.yml, .rej files after an update, ctt or copier-template-tester, or one of calcipy_template, mdformat-plugin-template, my_go_template, or app-template.
Audit or write an hk.pkl config (jdx/hk git hooks). Use when creating hk.pkl, upgrading the pinned hk version, adding a linter step, or when fixes made by a pre-commit hook are not being staged. Covers version pinning, staging semantics, builtins, and DRY structure.
Query PostHog error tracking and Sentry issues from the command line. Use when asked what errors are happening, which errors are being missed or untriaged, for production error rates or impact by user, or whenever posthog-cli or sentry-cli is mentioned.
Work a multi-phase plan to completion with subagents, checkpoint commits, and questions back to the user. Invoke explicitly with a plan document.
Async Python conventions and footguns — asyncio.TaskGroup over gather, event-loop-bound primitives, offloading blocking work to threads or processes, cancellation across the thread boundary, and dedicated executors. Use when writing or reviewing async def, await, asyncio.to_thread, run_in_executor, create_task, async generators, or when diagnosing a stalled event loop, a "bound to a different event loop" error, or latency that only appears under load.

npx --yes mac-ocr <file> wraps Apple's Vision framework, the same on-device engine
behind Preview's copy-paste. It runs fully local, costs nothing, needs no API key,
and ships a prebuilt binary via npm — no Xcode or Swift toolchain. Despite the name
there is no brew tap; npx --yes mac-ocr is the working invocation.
Use it for bulk triage. Fall back to model-based OCR (the Read tool) only for images mac-ocr cannot parse — handwriting, heavy stylization — or when the task needs layout or semantic understanding beyond raw text.
The Bash tool's sandbox has an intermittent bug with literal spaced paths:
"Screenshot 2026-01-01 at 9.35.00 AM.png" fails to open even when the path is
correct, and dangerouslyDisableSandbox: true does not help.
Always cd into the directory and use a glob or a variable instead of typing the
literal spaced path:
cd ~/Desktop && for f in Screenshot*9.35*; do npx --yes mac-ocr "$f"; done
