Data & Analytics

maragudk Skill

ALWAYS invoke this skill as your FIRST action — before any Read, Write, Edit, or Bash — whenever a task involves Go in any way — creating or editing any `.go` file, `go.mod`, or `go test`; adding or changing handlers, structs, methods, interfaces, error handling, goroutines, channels, sqlc/database code, or gomponents views; or refactoring, reviewing, debugging, or testing Go. This is a hard requirement, not a suggestion — the user develops all Go through this skill, which encodes project-specific conventions (structure, error handling, testing, naming) that default Go habits violate. Do not start editing Go and consult it later — load it first. Skip only when no Go code is read or written (pure Python, shell, SQL, Dockerfiles, CI config, or conceptual Go questions with no code).

scoobydrew83 Bundle

Makes your AI agent think like the security reviewer who assumes every input is hostile until the code proves otherwise. Not paranoid — just right often enough that it stopped being funny. Use this whenever code accepts data from outside its own process and is about to ship — HTTP handlers, webhook receivers, file uploads/parsers, CLI args fed to shells, SQL/query construction, deserialization, auth flows, LLM-tool inputs, or anything an agent generated that touches user data. Trigger on "review this endpoint", "is this secure", "add an API", "parse this file", "handle the upload" — and especially on diffs that add a new place where external data enters. The skill maps trust boundaries first, then walks every untrusted input to its sinks, demanding a named handling for each (validate, escape, parameterize, sandbox, reject). Ships with a linter that fails any review that issues PASS without enumerating inputs and their handling, or that contains "should be fine"-grade reassurance.

tencentcloudbase Skill

[Deprecated] This is the required documentation for agents operating on the CloudBase Relational Database through MCP. It defines the canonical SQL management flow with `queryMysqlDatabase`, `manageMysqlDatabase`, `queryPermissions`, and `managePermissions`, including MySQL provisioning, destroy flow, async status checks, safe query execution, schema initialization, and permission updates. New environments should use PostgreSQL — see postgresql-development skill instead.
