copilot-instructions
Generate or update .github/copilot-instructions.md for GitHub Copilot. Use when: (1) User wants to create Copilot instructions, (2) User asks to update existing Copilot guidelines, (3) User mentions 'copilot instructions', 'copilot guidelines', or 'copilot config'. Explores codebase for tech stack, file conventions, import patterns, code style, testing. Creates actionable instructions with code examples.
Best use case
copilot-instructions is best used when you need a repeatable AI agent workflow instead of a one-off prompt.

SKILL.md Source
Generate or update the `.github/copilot-instructions.md` file for this repository. **Instructions:** 1. **Check if `.github/copilot-instructions.md` exists:** - Use the Read tool to check if the file exists 2. **If the file does NOT exist:** - Explore the codebase using the Task tool with subagent_type=Explore - Focus on understanding: - Tech stack (frameworks, libraries, languages) - File naming conventions - Import patterns - Component/module structure patterns - Code style (formatting rules, linting config) - Testing approach - Key types and data structures - Common patterns to follow - Generate a comprehensive `.github/copilot-instructions.md` file - Write natural language instructions in Markdown format - Include critical conventions that developers must follow - Provide code examples for common patterns 3. **If the file DOES exist:** - Read the existing `.github/copilot-instructions.md` file - Explore the codebase carefully using the Task tool with subagent_type=Explore - Identify: - New patterns or conventions not documented - Outdated information that needs updating - Missing important guidelines - Areas that need better examples - Update the file with improvements - Preserve existing good content - Add new sections for newly discovered patterns - Remove or update outdated information 4. **Content Guidelines:** - Use clear, natural language - Focus on actionable patterns and conventions - Include code examples liberally - Highlight critical "must follow" rules - Reference key files to check for patterns - Keep instructions concise but comprehensive - Organize by topic (naming, imports, components, testing, etc.) 5. **After creating/updating:** - Inform the user about what was created or changed - Highlight key conventions that were documented - Suggest reviewing the file before committing **Note:** This creates GitHub Copilot custom instructions following the official format documented at https://docs.github.com/en/copilot/how-tos/configure-custom-instructions/add-repository-instructions

zudoesa-articlify
Convert conversation context into an esa article via the zudoesa-writer subagent. ONLY invoke when the user explicitly asks — NEVER proactively propose. Triggers: 'write esa article', 'esa記事', 'esaに書いて', 'articlify for esa', or /zudoesa-articlify. Gathers context, creates a writing brief, delegates to the writer subagent.

xlsx
Spreadsheet creation, editing, and analysis. Use when working with .xlsx, .xlsm, .csv, .tsv files for: (1) Creating spreadsheets with formulas and formatting, (2) Reading or analyzing data, (3) Modifying existing spreadsheets while preserving formulas, (4) Data analysis and visualization, (5) Recalculating formulas.
x
Facade for development workflows. Routes on two axes: plan-first vs implement-now (escalates to /big-plan -a when the request needs research / decomposition / has unclear scope — the appended -a makes the plan chain into implementation in-session), then single vs multi on the ready-to-build fast paths (/x-as-pr single-topic, /x-wt-teams multi-topic parallel). Use when: (1) User says '/x' followed by dev instructions, (2) User wants to start development without choosing the workflow skill, (3) User says 'dev', 'implement', or 'build' with a task. Default option: -v (verify-ui). Review-loop (-l) is opt-in — without -l the downstream skill runs a single /deep-review pass. Forwards -a (autonomy/auto-chain) and -m (merge at the end + cleanup + CI watch) through every route; auto-fix of raised findings (-f) and issue-raising (-ri) are downstream defaults, with -nf/--no-fix and -nori/--no-raise-issues as the forwarded opt-outs. -a and -m are orthogonal — full hands-off end-to-end is -a -m.
x-wt-teams
Parallel multi-topic development using git worktrees, base branches, and Claude Code agent teams. Use when: (1) User wants to work on multiple related features in parallel, (2) User mentions 'worktree', 'base branch', 'parallel development', 'split into topics', or 'multi-topic'. FULLY AUTONOMOUS — creates worktrees, spawns teams, coordinates everything. Also supports Super-Epic child mode for [Epic] issues from /big-plan with '**Super-epic:** #N' markers (targets the super-epic base branch instead of main).
x-as-pr
Start a development workflow as a draft PR. Creates a NEW branch from the current branch, empty start commit, draft PR targeting the current branch, then implements. ALWAYS creates a new branch by default — produces a nested PR-on-PR when the current branch already has one. Use when: (1) User says 'dev as pr', (2) User wants a PR-first workflow before coding, (3) User passes -s/--stay to reuse the current branch instead of nesting, (4) User passes a GitHub issue URL to implement, (5) User passes --make-issue/--issue to create an issue first. Logs progress via issue comments when an issue is linked.
watch-ci
Watch GitHub PR CI checks in the background and notify on completion. Use when: (1) User wants to monitor CI/CD status, (2) User says 'watch CI', 'check CI', 'monitor checks', or 'wait for CI', (3) User wants to know when checks pass or fail. Runs a background gh polling shell loop (NOT a subagent — near-zero token cost), sends macOS notification on completion. Also handles merged PRs by watching the target branch CI.
w-update-wording-rule
Add or update wording rules (表記ルール) in the w repo's vocabulary-rule.md files. Use when: (1) User says 'add wording rule', 'update wording rule', '表記ルール追加', (2) User wants to add a kanji/hiragana usage rule, (3) User provides a rule like 'X should be Y' with examples.
