Search callers, dependents, and linked systems before changing code.
Autonomous research workflows with zero external dependencies (built-in tools + free APIs only). Use when the user asks to (1) survey literature on a topic and produce a cited research report ("调研X"、"文献综述"、"deep research"), (2) run an autonomous experiment loop to improve a metric ("自动实验"、"跑实验优化X"、"autoresearch"), (3) reproduce a paper as code ("复现这篇论文"、"paper to code"), or (4) write/polish an academic paper and verify its citations ("写论文"、"校验引用"、"citation check"). Covers paper search (arXiv/Semantic Scholar/OpenAlex/Crossref), cross-source fact checking, experiment verification, and bibliography auditing.
Deep research on any topic using parallel sub-agents and built-in tools only (WebSearch/WebFetch + free APIs, no keys). Use when the user asks for a thorough multi-source investigation with a cited report — "深度调研X"、"deep research"、"帮我全面研究一下"、"多方求证"、"写一份调研报告". NOT for simple lookups (single WebSearch suffices) and NOT for academic literature surveys (use auto-research skill instead).
Use this skill whenever a Microsoft Word (.docx) file is being produced, opened, transformed, or read. That includes: drafting reports, letters, contracts, RFPs, technical documents, or any long-form written deliverable; extracting text or structure from an existing Word file; filling a Word template with values; converting Word to PDF or plain text; splitting or merging documents; inspecting styles, headings, sections, tables, images, comments, or tracked changes. Trigger on mentions of 'Word doc', 'DOCX', 'Office document', a filename ending in .docx, or requests like 'turn this into a Word report'.
Use when you want to modify ANY aspect of yourself — your capabilities (new/overridden tools), your behavior (hooks that intercept every tool call, LLM request, session and subagent lifecycle), your knowledge (skills that persist across sessions), your orchestration (workflow scripts), or even your UI (TUI panels, commands, dialogs). Nothing about you is fixed: every layer from what tools you expose, to how you react to events, to what the user sees on screen is rewritable through files in .zethcode/. Use proactively — repeated manual sequence 3+ times, repeated user correction, durable project knowledge, or any "I wish I could..." moment is a trigger to evolve.
Modern Python project setup with uv, ruff, and pyright. Use when initializing a new Python project, configuring the Python environment, setting up linting/formatting, or when a project needs uv (the fast Python package manager). Trigger on: 'set up Python', 'new Python project', 'configure uv', 'install uv', 'ruff', 'pyright', 'Python linting', 'Python formatting', or when a task requires Python and no pyproject.toml exists yet.
Use this skill whenever a PDF file is being produced, opened, transformed, filled, or read. That includes: extracting text or tables from an existing PDF; combining, carving, rotating, cropping, or watermarking pages; composing a fresh PDF (report, invoice, certificate); filling AcroForm fields or overlaying text onto a non-fillable scanned form; encrypting or unlocking a PDF; running OCR over a scanned document; rendering pages to PNG/JPEG for visual analysis. Trigger on mentions of 'PDF', a filename ending in .pdf, requests like 'turn this into a PDF report', or references to AcroForm / form fields.
Use this skill whenever a Microsoft PowerPoint (.pptx) file is being produced, opened, transformed, or read. That includes: authoring slide decks, pitch decks, executive readouts, training material, or any presentation deliverable; extracting text or structure from an existing .pptx; filling a .pptx template with values; converting a deck to PDF or images; splitting or merging decks; inspecting slides, layouts, masters, tables, images, charts, speaker notes, or comments. Trigger on words like 'deck', 'slides', 'presentation', 'pitch deck', 'keynote' (when a .pptx is expected as output), or any filename ending in .pptx. Do NOT trigger when the primary deliverable is a Word document, spreadsheet, PDF report, HTML site, or Google Slides API call, even if presentation-shaped content appears along the way.
