secondlayer

Receives CSS and HTML changes made in CSS Studio via MCP and applies them to source code.

Analyze the Secondlayer codebase and identify exactly ONE high-leverage, low-risk quality-of-life improvement. Use when: user runs "/quality-of-life", asks for "a quick win", "something to improve", "code quality check", or "what should I clean up next".

Run a production smoke sweep against secondlayer prod — container health, husk canaries, decoder lags, op queue budgets, public subgraph reads, balance conservation, known-bug regression probes. Use when the user runs "/prod-smoke", asks to "smoke test prod", "check prod health", "is everything running smoothly", or "verify the subgraphs".

Use Secondlayer to build on the Stacks blockchain — index on-chain activity into typed Postgres tables (subgraphs), stream raw and decoded events (Streams + Index), deliver row-level webhooks (subscriptions), and call Clarity contracts from a viem-style TypeScript SDK. Invoke this skill whenever the user mentions Secondlayer, `sl`, the `@secondlayer/*` packages, Stacks indexing, sBTC, BNS, PoX/stacking, Clarity contract reads/calls, post-conditions, webhook subscriptions on chain events, or asks how to query, watch, or react to anything happening on the Stacks chain — even if they don't name Secondlayer explicitly.

Analyze Stacks ecosystem signals and map them to high-value product, marketing, security, and onboarding opportunities buildable with secondlayer tools (Index, Subgraphs, Streams, CLI, SDK, @secondlayer/stacks, MCP). Use when the user pastes a Stacks Discord "this week in Stacks" announcement digest, or points at any single source — a Hiro GitHub issue, a forum/X thread, a dev complaint about the Hiro API or another service, a protocol launch, or a historical hack/exploit writeup — and wants it parsed, its links fetched and analyzed, and turned into ranked opportunities for product validation, developer onboarding, ecosystem/dev-need solutions, security tooling, or brand content. Triggers on "scout the announcements", "stacks opportunities", "what can we build from this", "analyze this for product opportunities", "ecosystem scan".

Create a changelog, launch, announcement, or milestone video for ANY repo / package / release using the cadence CLI. Use whenever someone wants a video, reel, teaser, or animated showcase for a software feature, release, PR, changeset, SDK/CLI update, or milestone — phrasings like "make a changelog video for <repo>", "announcement video for the v2 release", "showcase the new <feature>", "a reel for our latest npm release", "render a 9:16 of <project>'s changelog", "milestone video — 1M downloads". Point it at a local repo path or a GitHub repo. It reads the project, writes a small data file, and renders an MP4. Trigger even when the user doesn't say "Remotion", "beats", or "render".
