shipshitdev Bundle

Provides 41 prioritized performance rules for React Hook Form across form configuration, field subscription, controlled components, validation, and field arrays. Invoke when writing or reviewing forms with useForm, useWatch, useController, or useFieldArray; integrating shadcn/MUI with Controller; or diagnosing unexpected re-renders in RHF-based forms. Covers client-side validation only — does not cover React Server Actions or useActionState.

shipshitdev Bundle

Use when implementing authentication or authorization, reviewing code for vulnerabilities, handling sensitive data, or implementing encryption or hashing.

shipshitdev Bundle

React Testing Library best practices for writing maintainable, user-centric tests. Use when writing, reviewing, or refactoring RTL tests. Triggers on test files, testing patterns, getBy/queryBy queries, userEvent, waitFor, and component testing.

shipshitdev Bundle

Diagnose slow React components and suggest targeted performance fixes. Use when profiling or improving a slow React component, or reducing re-renders, list lag, or expensive render work.

fabioc-aloha Skill

Read a chart someone else made — image, screenshot, HTML, or dashboard — and extract insights, patterns, anomalies, and misleading framing. The reverse of authoring. Use when handed a chart to analyze, when checking whether a chart's visuals support its claim, or when a figure needs a written narrative.

carlheath Skill

Use this skill any time a spreadsheet file is the primary input or output. This means any task where the user wants to: open, read, edit, or fix an existing .xlsx, .xlsm, .csv, or .tsv file (e.g., adding columns, computing formulas, formatting, charting, cleaning messy data); create a new spreadsheet from scratch or from other data sources; or convert between tabular file formats. Trigger especially when the user references a spreadsheet file by name or path — even casually (like "the xlsx in my downloads") — and wants something done to it or produced from it. Also trigger for cleaning or restructuring messy tabular data files (malformed rows, misplaced headers, junk data) into proper spreadsheets. The deliverable must be a spreadsheet file. Do NOT trigger when the primary deliverable is a Word document, HTML report, standalone Python script, database pipeline, or Google Sheets API integration, even if tabular data is involved.

octanejs Skill

Find and fix a bug in the octane monorepo. Use when given a failing test, a regression, or a report that behavior differs from expectation, including deciding whether a React mismatch is an intentional divergence.

octanejs Skill

Write a new Octane component in .tsrx, convert JSX to .tsrx, or add scoped <style> blocks and themes. Use when creating a .tsrx file rather than editing one, because the path-scoped tsrx-authoring rule only fires once such a file is open.

octanejs Skill

Compatibility entry point for React-library work in Octane; routes existing-binding maintenance to update-bindings and actual React implementation ports to octane-react-library-port.

octanejs Bundle

Implement and verify new React-library ports or copied/rewritten React surfaces in Octane bindings from npm names or npm/GitHub links/lists. Enforces immutable provenance, license boundaries, dependency ordering, full-surface parity, and machine evidence. Existing-binding audits and maintenance start with update-bindings.

dailybothq Bundle

Optional DeepWorkPlan addon that gives a repo with a user-facing interface surface a DESIGN.md (under docs/, indexed from AGENTS.md) — a Markdown design-system file any coding agent reads to generate interface output consistent with the repo's OWN conventions. Covers three profiles detected independently from real files — visual-ui (rendered web/mobile/desktop UI), cli-output (styled terminal output — semantic colors, panels, spinners, prompts, TTY/NO_COLOR degradation), and conversational (chat/email messaging — voice and register, message anatomy, per-platform rendering). Reasons about the repo's ACTUAL design source (CSS custom properties, Tailwind config, token files, component styles, a CLI display/theme module, or message-composition helpers) rather than copying a brand file; checks contrast (WCAG AA), color-is-not-the-only-carrier, plain-text fallbacks, and token integrity. The visual-ui profile is default-on when detected (applied in trust mode, strongly recommended in guided mode); cli-output and con

green-pt Skill

Same pixels, fewer tokens. For user-facing markup: keeps the full design, expresses it densely with CSS vars, shorthand, fluid units.

Covers entry points, happy paths, alternate paths, error states, friction analysis, and delight opportunities. Do not use for individual component interaction specs (use interaction-design).
