pdf-combine
Combine multiple PDF files into a single PDF. Use when: (1) User wants to merge PDF files, (2) User mentions 'combine PDFs', 'merge PDFs', or 'join PDFs', (3) User has multiple PDFs that need to be consolidated. Respects file order: when given a directory, files are sorted alphabetically; when given specific file paths, the order provided is preserved.
Best use case
pdf-combine is best used when you need a repeatable AI agent workflow instead of a one-off prompt.

# Combine PDF Files Combine multiple PDF files into a single PDF document. ## Usage The user can specify: - A directory containing PDF files (files will be sorted alphabetically by filename) - Multiple specific PDF file paths (order is preserved as given) - Output file path for the combined PDF ## Script Details - **Script location**: `$HOME/.claude/skills/pdf-combine/scripts/combine_pdfs.py` - **Dependency**: PyMuPDF (fitz) - `pip install PyMuPDF` ## Instructions 1. Determine the source PDF files: - If user provides a directory, all PDFs in that directory will be combined in alphabetical order - If user provides specific file paths, use them in the exact order provided 2. Determine the output file path: - If user specifies an output path, use it - If not specified, ask the user for the output file name/path 3. Run the combine script: ```bash python3 $HOME/.claude/skills/pdf-combine/scripts/combine_pdfs.py <input1.pdf> <input2.pdf> ... -o <output.pdf> ``` Or for a directory: ```bash python3 $HOME/.claude/skills/pdf-combine/scripts/combine_pdfs.py <directory> -o <output.pdf> ``` 4. Report the results to the user (number of files combined, total pages, output location) ## Examples ### Combine specific files in order ```bash python3 $HOME/.claude/skills/pdf-combine/scripts/combine_pdfs.py \ chapter1.pdf chapter2.pdf chapter3.pdf \ -o book.pdf ``` ### Combine all PDFs in a directory (alphabetical order) ```bash python3 $HOME/.claude/skills/pdf-combine/scripts/combine_pdfs.py \ ./documents/ \ -o combined.pdf ``` ## Order Rules - **Directory input**: Files are sorted alphabetically by filename (case-insensitive) - **Explicit file list**: Files are combined in the exact order provided by the user - If user wants a specific order for files in a directory, they should provide the files explicitly ## Error Handling - If a file doesn't exist, the script will report an error - If no PDF files are found in a directory, the script will report an error - Non-PDF files are skipped with a warning

zudoesa-articlify
Convert conversation context into an esa article via the zudoesa-writer subagent. ONLY invoke when the user explicitly asks — NEVER proactively propose.

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.
