In-memory caching in Golang using samber/hot — eviction algorithms (LRU, LFU, TinyLFU, W-TinyLFU, S3FIFO, ARC, TwoQueue, SIEVE, FIFO), TTL, cache loaders, sharding, stale-while-revalidate, missing key caching, and Prometheus metrics. Apply when using or adopting samber/hot, when the codebase imports github.com/samber/hot, or when the project repeatedly loads the same medium-to-low cardinality resources at high frequency and needs to reduce latency or backend pressure.
Write and diagnose YouTube Shorts that hold attention on the Shorts Feed and route viewers into your long-form. Use when someone wants a shorts script, a shorts hook tuned for VVSA and the first 3 seconds, a fix for a flopping short, a read on whether to link a short to a long-form video, or a plan to build the shorts to long form funnel for their channel. Covers what the youtube shorts algorithm rewards now that the Shorts feed runs separately from long-form, how shorts retention is measured, and the youtube shorts strategy choices that move RPM (licensed music split, Creator Pool math, Engaged Views). Pattern-based viral shorts guidance grounded in how shorts tend to perform.
Write captions, on-screen text, hashtags, and CTAs for short-form video that earn saves and sends without tripping engagement-bait penalties. Use when someone asks for a viral caption, an instagram caption or tiktok caption or video caption, wants to fix a weak cta or call to action, asks about hashtag strategy and whether to add hashtags, wonders what the right pinned comment or comment seeding play is, or needs a gut check on whether their copy is engagement bait. Covers caption length sweet spots per platform, the first-line cutoff, on-screen text patterns for muted watching, native versus cross-posted copy, how hashtags actually work now, send-driving and save-driving CTAs, pinned comment tactics, and the anti-patterns that suppress reach. Pattern-based guidance grounded in how captions and CTAs tend to perform; it improves the odds, it does not guarantee virality.
Generate short-form video ideas at volume and stop the blank-page problem for good. Use whenever someone says they're stuck for ideas, asks for 20 TikTok ideas or Reels ideas or YouTube Shorts ideas for their niche, wants a content brainstorm, needs help building a content pillar system or content matrix, wants to turn one idea into 5 angles, asks what to post this week, or wants a real idea generator workflow instead of staring at a notes app. Runs the systems prolific creators actually use: pillars, mining (comments, Reddit, search autocomplete, competitor outliers), repurposing, evergreen vs trend balance. Pattern-based guidance grounded in how short-form ideation tends to work; never run out of ideas is the goal, virality is not promised.
Write and critique viral hooks for short-form video: the opening 1 to 3 seconds that decide whether anything else gets seen. Use this when you need a batch of hook ideas for a video, want to make a weak opening line stronger, are picking which hook archetype fits an idea, or want a critique of a draft hook against proven patterns. Covers the three-layer hook (visual, verbal, on-screen text), the named-creator frameworks (Kallaway, MrBeast, Hormozi, Brunson, Koe, Welsh, Bush, Galloway), scroll-stopping hook tactics, and the anti-patterns that tank first-three-seconds retention. Works across TikTok, Reels, and Shorts. Pattern-based guidance that improves the odds. It does not guarantee virality.
Plan, write, and diagnose Instagram Reels that earn cold-audience reach. Use whenever someone wants a reels script or reels hook for a specific Reel, is debugging why a Reel flopped, wants to know if a draft is worth testing with Trial Reels before going public, or needs a reels caption tuned for the post-hashtag instagram algorithm. Built around what Mosseri has publicly named as the signal hierarchy (watch time, sends per reach, likes per reach), the Trial Reels test-then-publish loop, the Original Content Guidelines and 30-day recovery window, the Edits app, and Reels Insights metrics (skip rate, share rate, followers from this post). Covers a Reels-specific reels strategy: send-driving CTAs, originality without watermarks, audio licensing by account type, captions as the primary SEO signal, and the anti-patterns that quietly cap distribution. Pattern-based guidance, not a virality promise.
Write a tiktok script, a tiktok hook, or a fresh tiktok video idea shaped for how the FYP actually ranks content. Use when someone asks for a tiktok hook for X, wants a script made tiktok-shaped, asks whether a clip is a tiktok or a Reel, wants to improve a tiktok video they drafted, or wants to know what tiktok trends are worth riding this week. Covers the tiktok algorithm signals (user interactions, video information, device and account), completion-rate math by length, trending sound timing, duets, stitches, TikTok Shop pacing, and the AI disclosure regime. Pattern-based guidance for viral tiktok content; it improves the odds of landing on fyp, it does not promise virality.
Golang OpenAPI/Swagger documentation with swaggo/swag — annotation comments (@Summary, @Param, @Success, @Router, @Security), swag init code generation, framework integrations (gin, echo, fiber, chi, net/http), security definitions (Bearer/JWT, OAuth2, API key), and struct tags (swaggertype, enums, example, swaggerignore). Apply when adding or maintaining Swagger/OpenAPI docs in a Go project, or when the codebase imports github.com/swaggo/swag, github.com/swaggo/gin-swagger, github.com/swaggo/echo-swagger, github.com/swaggo/http-swagger, or github.com/swaggo/files.
Implements GraphQL APIs in Golang using gqlgen or graphql-go. Apply when building GraphQL servers, designing schemas, writing resolvers, handling subscriptions, or integrating GraphQL with existing Go HTTP services. Also apply when the codebase imports `github.com/99designs/gqlgen` or `github.com/graph-gophers/graphql-go`.
Golang CLI command tree library using spf13/cobra — cobra.Command, RunE vs Run, PersistentPreRunE hook chain, Args validators (NoArgs, ExactArgs, MatchAll, custom), persistent vs local flags, command groups, ValidArgsFunction, RegisterFlagCompletionFunc, ShellCompDirective, usage/help template customization, man-page and markdown doc generation, and testing with SetArgs/SetOut/SetErr. Apply when using or adopting spf13/cobra, or when the codebase imports `github.com/spf13/cobra`. For configuration layering alongside cobra, see the `samber/cc-skills-golang@golang-spf13-viper` skill. For general CLI architecture (project layout, exit codes, signal handling, I/O patterns), see `samber/cc-skills-golang@golang-cli`.
Golang application framework using uber-go/fx — fx.New, fx.Provide, fx.Invoke, fx.Module, fx.Lifecycle hooks, fx.Annotate (name/group/As), fx.Decorate, fx.Supply, fx.Replace, fx.WithLogger, and signal-aware Run(). Apply when using or adopting uber-go/fx, when the codebase imports `go.uber.org/fx`, or when wiring services with fx.New. For raw DI without lifecycle, see `samber/cc-skills-golang@golang-uber-dig` skill.
Golang configuration library using spf13/viper — layered precedence (flag > env > file > KV > default), BindPFlag/BindPFlags, SetEnvPrefix + SetEnvKeyReplacer + AutomaticEnv, ReadInConfig + ConfigFileNotFoundError, Unmarshal + mapstructure struct tags, Sub for sub-trees, WatchConfig + OnConfigChange for hot reload, viper.New() for test isolation, and remote KV integration. Apply when using or adopting spf13/viper, or when the codebase imports `github.com/spf13/viper`. For CLI command structure alongside viper, see the `samber/cc-skills-golang@golang-spf13-cobra` skill. For general CLI architecture, see `samber/cc-skills-golang@golang-cli`.
