Firebase gives you a complete backend in minutes - auth, database, storage, functions, hosting. But the ease of setup hides real complexity. Security rules are your last line of defense, and they're often wrong.

Configure the OpenTelemetry Collector with Sentry Exporter for multi-project routing and automatic project creation. Use when setting up OTel with Sentry, configuring collector pipelines for traces and logs, or routing telemetry from multiple services to Sentry projects.

Comprehensive code review for diffs. Analyzes changed code for security vulnerabilities, anti-patterns, and quality issues. Auto-detects domain (frontend/backend) from file paths.

Access security tokens and smart cards using CryptoTokenKit. Use when building TKTokenDriver or TKSmartCardTokenDriver extensions, communicating with smart cards via TKSmartCard/TKSmartCardSlotManager, using iOS 26+ NFC smart-card sessions, registering smart cards, querying token-backed keychain items with kSecAttrTokenID, monitoring TKTokenWatcher, or configuring certificate-based smart-card authentication.

Ensure renamed built-in tool references preserve backward compatibility. Use when renaming a toolReferenceName, tool set referenceName, or any tool identifier. Run on ANY change to tool registration code. Covers legacyToolReferenceFullNames for tools and legacyFullNames for tool sets.

Debug HWP layout, dump document IR, compare versions, extract thumbnails, and unlock read-only HWPs with the upstream rhwp Rust CLI (export-svg/dump/dump-pages/ir-diff/thumbnail/convert).

Share or open-source any project the user has built — a running preview/service, a project directory, a dashboard, or scripts. Use whenever the user wants to publish, share, make public, list, distribute, deploy publicly, or open-source something. Three independent actions — publish_preview (allocate a public URL for a running service), list_in_dashboard (show it on the public Project Dashboard for discovery), open_source (push project source to the community GitHub repo). Do NOT search the filesystem for publish-related code or write custom deploy/upload scripts — this skill is the single entry point.
