- ai-seoWhen the user wants to optimize content for AI search engines, get cited by LLMs, or appear in AI-generated answers. Also use when the user mentions 'AI SEO,' 'AEO,' 'GEO,' 'LLMO,' 'answer engine optimization,' 'generative engine optimization,' 'LLM optimization,' 'AI Overviews,' 'optimize for ChatGPT,' 'optimize for Perplexity,' 'AI citations,' 'AI visibility,' 'zero-click search,' 'how do I show up in AI answers,' 'LLM mentions,' 'optimize for Claude/Gemini,' 'llms.txt,' 'llms-full.txt,' 'OKF,' 'Open Knowledge Format,' 'knowledge bundle,' 'agent-readable site,' 'agent readiness,' 'is my site agent-ready,' 'WebMCP,' 'do listicles still work for AI,' 'ChatGPT stopped citing comparison pages,' 'how do LLMs see our brand,' 'LinkedIn for AEO,' or 'AI citation format shift.' Use this whenever someone wants their content to be cited or surfaced by AI assistants and AI search engines. For traditional technical and on-page SEO audits, see seo-audit. For structured data implementation, see schema.
- gating-sensitive-actionsUse when deciding whether an endpoint, settings section, or UI flow should require recent authentication (re-auth), when adding `TimeSensitiveActionPermission` or its exemptions (`time_sensitive_allow_if_only_fields`, `time_sensitive_exclude_actions`, `time_sensitive_allow_actions`), when wrapping a page or settings section in `TimeSensitiveAuthenticationArea`, when an API read returns secret material, or when a write fails with `sensitive_action_required_reauth`. Carries the product decision: reads stay open, only sensitive writes need a fresh session, and the backend enforces it; organization settings are the one area gated on navigation. Covers how the frontend opens the re-auth modal and retries the failed request, and how to test a new gate. Trigger terms: re-auth, reauthenticate, reauthentication, sensitive session, fresh session, sudo mode, step-up, TimeSensitiveActionPermission, TimeSensitiveAuthenticationArea, sensitive_action_required_reauth.
- Pest Testing FrameworkIntegration with the Pest PHP testing framework for writing and running tests
- asc-analytics-reportsCollect, download, and verify App Store Connect Analytics reports with asc. Use when users need to discover analytics report requests, select report instances by processing date or granularity, download every segment, or verify downloaded files against Apple's size and MD5 metadata before analysis.
- launchShipyard's governed delivery pipeline — converge the mission, synthesize a durable spec, decompose vertical-slice tickets with blocking edges, run the frontier in parallel via team, close with verification, and report with a full decision log. Two entry gates — the yard gate (drydock audit) and the fog gate (an effort whose destination is unclear is routed to /ask-navigator before this pipeline starts). Humans own the checkpoints where there is no unique answer or the error cost is severe; agents continuously run everything repeatable and acceptable-by-evidence.
- customizing-commandsCreates, edits, and enables Letta Code mod-provided slash commands. Use when the user asks to add a custom /command, slash command, command shortcut, scoped conversation-backed command, or command-driven panel behavior.
