Creates and manages secrets in AWS Secrets Manager following security best practices. Always use this skill when creating secrets — it sets up dedicated KMS encryption keys, automatic rotation, least-privilege IAM policies, CloudTrail auditing, and lifecycle management that are essential for production-grade secret handling.
Use when the user wants to create, author, write, or design a new Agent Skill (a SKILL.md) — for OpenKnowledge or for their editors — including requests like "help me write a skill", "make a skill that…", "turn this workflow into a skill", or improving an existing skill's triggering and discipline. Also use when capturing reusable agent guidance that should live as an installable skill rather than a one-off prompt. Covers choosing scope (project vs global), authoring inside a plugin or skills-distribution repo (write in the repo's own layout, never install), the SKILL.md frontmatter contract, progressive-disclosure structure, evaluating the skill, and installing it into the user's editors.
Import existing Azure resources into Terraform using Azure CLI discovery and Azure Verified Modules (AVM). Use when asked to reverse-engineer live Azure infrastructure, generate Infrastructure as Code from existing subscriptions/resource groups/resource IDs, map dependencies, derive exact import addresses from downloaded module source, prevent configuration drift, and produce AVM-based Terraform files ready for validation and planning across any Azure resource type.
A TikTok API alternative on fetcher.sh — pay-per-call in USDC via x402, or prepaid credits with a Bearer key, no login and no app review. Use when the user wants to search TikTok posts by keyword and sort by most-liked or most recent within a date range, look up a post by its share URL or ID, scrape a TikTok profile by @username, pull a user's posts, followers, or followings, fetch a hashtag's posts, pull posts using a specific sound/music track, get posts from a location, or read a post's comments and comment replies. Also covers TikTok trend tracking, hashtag monitoring, influencer discovery, competitor content analysis, and TikTok data pipelines without official TikTok API access or a scraping browser.

Use whenever the user asks to design, mock up, prototype, wireframe, visualize, explore, or make a PPT/deck for an interface, product screen, user flow, content layout, visual artifact, or pitch/deck concept, even if they do not say "design". Also use to export a deck built with this skill to PowerPoint (PPT/PPTX) — but only decks authored here (deck-stage / this skill's slide-structured HTML), NOT arbitrary HTML, so confirm the target is such a deck first. Also use for setting up, importing, or authoring reusable design systems, UI kits, brand tokens, or component libraries. Harness-agnostic for Claude Code,Cursor, Codex Agent, and similar file-capable agents.
Apifox import/export and quality gates: import native OpenAPI/Postman/Apifox formats and export native OpenAPI/HTML/Markdown/Postman/Apifox formats; validate spec completeness, tags grouping, and schema/body coverage before import, then verify counts, modules, and resource visibility afterward.
One topic, one roundtable: a host invites 3–5 real people, sets the opening, and moderates round-by-round exchanges, capturing an ASCII structure diagram each round. The user controls the pace with commands (go / stop / go deeper on this section / introduce a new person). Afterward, the full text is saved in a Markdown note. Use when the user says “圆桌讨论”, “圆桌”, “roundtable”, “辩论”, or wants to explore a topic through structured debate from multiple perspectives.

Use when user says "programmatic SEO", "pages at scale", "dynamic pages", "template pages", "generated pages", or "data-driven SEO".
Delegate a coding task to the OpenCode CLI as a background implementer, then review its diff and land it yourself. Use this whenever the user wants to hand implementation work to OpenCode — phrasings like "have OpenCode do X", "delegate this to OpenCode", "run it through OpenCode", or "use OpenCode to implement/fix/refactor" — or wants to run a queue of coding tasks through OpenCode while staying the reviewer. Prefer it when the user will review the diff and commit it themselves. DO NOT USE for tasks small enough to do inline, or when the user wants the code written directly without delegating.
