Carry a config, pattern, or workflow from a sibling repository into this one. Use whenever a request references another local repo by relative path ("like ../calcipy", "see ../yak-shears/hk.pkl", "the way ../my-go-template does it"), or when migrating a project onto tooling another project already uses.

The user keeps many small repos plus two copier templates (calcipy_template for
Python, my_go_template for Go) and propagates changes in both directions. The
reusable part of that work is the checklist, not the copying.
Read the reference in full. Not just the file named — its config, its lockfile pins, and any AGENTS.md, CLAUDE.md, or ADR that explains why it is shaped that way. Reading the file alone reproduces the shape and loses the reason.
Diff against local. State what already exists here, what conflicts, and what is genuinely missing. A migration usually turns out to be smaller than it looked.
Adapt, do not copy. The reference repo has a different name, language version, dependency set, and CI. Strip what is specific to it. A pasted config that names the wrong package is worse than none.
Note where the two have deliberately diverged. If local does something differently on purpose, say so and ask before overwriting it. Do not silently converge them.
Run it. The pre-commit hook, the lint step, the test suite — whatever the ported config claims to do. A config that evaluates is not a config that works.
The step most often forgotten. When the change is a general improvement rather than project-specific, it belongs in the template so every future project gets it:
../calcipy_template/package_template../my_go_template../app-template, with rendered output regenerated
under .ctt/Say explicitly whether the change should propagate upstream, and ask if it is not clear. Do not commit to the template repo without being asked.
Porting template to project is a copier update — use the copier-template
skill rather than hand-copying, so .copier-answers.yml stays truthful.
Porting project to template is manual, and needs the specifics generalized back
into {{ }} placeholders.
Porting project to project is the plain case this skill covers.
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.
