Detect, select, switch, and verify Go toolchains for a repository without mutating global system state. Use when a Go build reports an incompatible GOROOT or standard-library package, when go.mod/go.sum behavior differs across Go versions, when multiple Go versions are installed, when choosing a Go binary for go mod tidy/test/build, or when setting up a repeatable multi-version Go workflow.
Generate speech, podcasts, voiceovers, and multi-speaker dialogue with Google AI Studio's Gemini Flash TTS by driving the live web app in Chrome via the claude-in-chrome MCP server. Use whenever the user asks to (1) create a podcast, audiobook chapter, narration, audio drama, or voiceover with Gemini / Google AI Studio TTS; (2) turn a script into multi-speaker audio (e.g. "two-host podcast", "Speaker 1 / Speaker 2 dialogue", "Puck and Zephyr"); (3) tweak a TTS prompt with Scene, Sample Context, Director's note (Style/Pace/Accent), Audio Profile, voice picker, or Temperature; or (4) render audio with inline tags like [enthusiastic], [whispers], [laughs]. Triggers on phrases like "use AI Studio TTS", "generate this podcast in AI Studio", "render with gemini-3.1-flash-tts-preview", "speak this with Aoede/Puck/Zephyr", or any request for browser-driven Gemini speech generation.
Use ChatGPT Web's GPT 5.6 Sol Pro as a verified second-opinion partner for difficult planning, architecture, debugging, business, product, content-strategy, risk-review, and Skill-design work. Use when the user asks for GPT 5.6 Sol Pro, ChatGPT Pro, a deeper outside judgment, or a file-grounded review. Default to the Codex Chrome plugin for text, model selection, file uploads, waiting, and extraction. Use OpenCLI only when the user explicitly requests it or the Chrome plugin is unavailable and OpenCLI passes preflight.
Keep iterating on code changes until the tests pass, the build succeeds, or linting is clean. Runs in a tight loop of fix → run → check → repeat. Use when you want the agent to autonomously grind through test failures or build errors.
Gravity and magnetic data processing and forward modelling using Fatiando a Terra. Use when the agent needs to: (1) Compute gravity forward models (point masses, prisms, tesseroids), (2) Apply terrain/Bouguer corrections, (3) Grid scattered potential field data with equivalent sources, (4) Perform upward/downward continuation, (5) Calculate magnetic anomalies from magnetized bodies, (6) Apply derivative filters (gradients, tilt angle), (7) Process regional or local gravity surveys.
HCCL (Huawei Collective Communication Library) performance testing for Ascend NPU clusters. Use for testing distributed communication bandwidth, verifying HCCL functionality, and benchmarking collective operations like AllReduce and AllGather. Covers MPI installation, multi-node pre-flight checks (SSH/CANN version/NPU health), and production testing workflows.
Side-route orientation skill. Use when the user asks 'what's next', 'where am I', or is returning to a repo mid-pipeline and wants to know which skill to run next. Reads repo state (branch, PRs, issues, research archive, milestones) and recommends one next step with a one-line reason. Not for executing work — only for routing.
Control Herdr, a terminal multiplexer for coding agents. Use Herdr to inspect or control panes, tabs, workspaces, terminals, run commands, and or starting and monitoring background processes like dev servers. Use for subagent when the user or another skills explicitly asks for or requies subagents. Requires HERDR_ENV=1.
Clarify priority and emphasis by fixing unclear primary actions, competing visual weight, loud section titles, and weak label/value treatment. Use when the user mentions hierarchy, prioritization, too much competition, grayscale confusion, loud headings, or unclear primary actions.
Use when the user asks to “create a hook,” “add a PreToolUse/PostToolUse/Stop hook,” “validate tool use,” “implement prompt-based hooks,” “use ${CLAUDE_PLUGIN_ROOT},” “set up event-driven automation,” “block dangerous commands,” or mentions hook events (PreToolUse, PostToolUse, Stop, SubagentStop, SessionStart, SessionEnd, UserPromptSubmit, PreCompact, Notification). Provides comprehensive guidance for creating and implementing Claude Code plugin hooks, focusing on the advanced prompt-based hooks API
Runs a hypothesis-driven threat hunt for supply-chain compromise (T1195) by querying SIEM/EDR logs for trojanized software updates, compromised dependencies, unauthorized code modifications, and tampered build artifacts. Use when hunting after threat intel flags a compromised vendor/dependency, scoping a build-pipeline compromise, or reviewing update/build integrity.
End-to-end video production pipeline with design thinking. 6-phase orchestrator: Discovery (design thinking + context) → Storytelling (narrative + storyboard) → Capture (Chrome DevTools screenshots/screencasts, native desktop or region screen recording where supported, asciinema terminal recording) → Design (HyperFrames scene templates) → Production (HyperFrames composition) → Audio & Render (media-use audio engine for voiceover, music and SFX; reviewed captions; hyperframes render). Starts from a video request and the current project's context; the request drives subject, scenario, detail, and results. Three content modes: promo (marketing), showcase (portfolio/demo), or tutorial (walkthrough/how-to). Triggers: "create video", "promo video", "showcase video", "tutorial video", "walkthrough video", "how-to video", "product video", "demo video", "launch video", "desktop app demo", "screen recording video", "record a screen region".
Research-backed UX best practices for Shopify Hydrogen storefronts, based on Baymard Institute (200,000+ hours of usability research) and Nielsen Norman Group studies. Use this skill WHENEVER the user is building, reviewing, or improving any part of a Shopify Hydrogen e-commerce site — including homepage, collection/listing pages, product pages, cart, checkout, search, filters, mobile UX, accessibility, or trust/credibility concerns. Also use when the user asks for code review on Hydrogen components, wants to scaffold a new route or component, or mentions conversion, cart abandonment, or shopping experience issues. Trigger even if the user doesn't explicitly say "UX" — any Hydrogen storefront work benefits from these guidelines.
When the user wants to create, generate, edit, or optimize images for marketing — blog heroes, social graphics, product mockups, profile banners, listing visuals, or brand assets.

Elite website image-to-code skill for Codex. For visually important web tasks, it must first generate the design image(s) itself, deeply analyze them, then implement the website to match them as closely as possible. In Codex, it must prefer large, readable, section-specific images instead of tiny compressed boards, generate fresh standalone images for sections or detail views instead of cropping old ones, avoid lazy under-generation, avoid cards-inside-cards-inside-cards UI, and keep the hero clean, spacious, readable, and visible on a small laptop.
Hardens Kubernetes RBAC by designing least-privilege Roles and ClusterRoles, auditing RoleBindings, eliminating cluster-admin sprawl, separating service accounts, and integrating an external OIDC identity provider. Use when tightening cluster access control, removing excessive ClusterRoleBindings, or hardening service-account permissions against escalation and lateral movement. Keywords: RBAC, Role, ClusterRole, RoleBinding, least privilege, service account, OIDC, cluster-admin. Do not use for discovering existing escalation paths - use auditing-kubernetes-rbac-privilege-escalation.
Use when optimizing CLAUDE.md, AGENTS.md, custom commands, or skill files — diagnose the concrete failure first, then apply current documented Anthropic best practices (explicit instructions, context/motivation, examples, output and verbosity control, thinking/effort, CLAUDE.md size and skill-description rules) instead of inventing improvements. Triggers when a prompt isn't followed, a skill won't activate, CLAUDE.md is too long or ignored, or migrating prompts to current Claude models.
Improve product interfaces with tasteful UI craft, micro-interactions, accessibility-preserving polish, and detail-oriented review. Use when building UI, reviewing components, improving perceived quality, making an interface feel better, or auditing forms, buttons, motion, typography, empty states, loading states, and navigation polish.
Unified issue discovery and creation. Create issues from GitHub/text, discover issues via multi-perspective analysis, or prompt-driven iterative exploration. Triggers on "issue:new", "issue:discover", "issue:discover-by-prompt", "create issue", "discover issues", "find issues".
JSON processing with jq for filtering, transforming, aggregating, and reshaping data from files, APIs, and command output on the command line. Use when processing JSON via command-line filters. Don't use for CSV/TSV (use xsv), YAML (use yq), or analytical queries requiring SQL (use duckdb).

Use this skill when the user says "升级 skills", "更新 li-skills", "li-skills 有新版本吗", "upgrade skills", or "skills 怎么更新". It should also trigger even if the user only asks "有新版本吗", and proactively run the upgrade process. Check the current version, run npx skills update or reinstall jiangjiax/li-skills, then prompt the user to restart the Claude Code session to load the new version. Use when the user wants to "upgrade skills", "update li-skills", or get the latest version of the li creator toolkit.
Use this skill when the user says "优化流程", "检查流程", "系统哪里有问题", "流程有漏洞", or "新增了 XX 功能，更新流程". Read documents such as CLAUDE.md and 工作流程.md, diagnose process gaps, identify automation opportunities, generate an optimization plan, and directly apply the changes, saving the optimization report to 04-方法论沉淀/. Should not trigger for: content creation tasks (use the corresponding li-* skill) or skill development (use li-factory). Use when the user wants to "optimize workflow", "check process", "improve system", or notices a gap in the content creation pipeline.

Use when the user wants to (1) scrape LinkedIn profiles for candidate data, (2) evaluate candidates against a job description, (3) generate boolean search strings for sourcing, (4) produce candidate scorecards, summaries, or comparison tables, or (5) any recruiting/talent-sourcing task involving LinkedIn data.
Align linting and formatting toolchains. Use when reviewing shared configuration; upgrading or migrating linters, formatters, presets, analyzers, or type-aware integrations; or removing plugins, overrides, suppressions, and duplicate commands with evidence.
Build and maintain a Karpathy-style LLM knowledge base — a self-compiling Obsidian markdown wiki where an Agent ingests raw sources, compiles cross-linked concept/entity/summary pages, answers queries against the corpus, lints the graph for health, and audits in-context human feedback filed from Obsidian or the local web viewer. Use when (1) scaffolding a new knowledge base for any research topic, (2) ingesting articles/papers/PDFs/web pages into raw/, (3) compiling or restructuring wiki articles from existing raw material, (4) answering questions against the wiki and filing durable answers back, (5) running lint passes for dead links / orphan pages / coverage gaps / audit shape, (6) processing human feedback from the audit/ directory and applying corrections. Not for general note-taking, daily journals, or non-wiki Obsidian use.
