AI & ML
AI & ML agent skills cover the machine-learning workflow itself: writing and evaluating prompts, building RAG pipelines, running evals, and wiring up model APIs. Each one is a SKILL.md file your agent loads on demand, so the know-how travels across Claude Code, Cursor, and 60+ agents.
-
bookforge-ai Bundle Web Presentation Pattern SelectorSelect the right web presentation pattern combination for any server-side web layer under design or refactor. Covers MVC (Model View Controller) decomposition, all three view patterns (Template View, Transform View, Two Step View), all three controller patterns (Page Controller, Front Controller, Application Controller), and when to layer Application Controller above the others for wizard or state-machine flows. Use when designing a new web layer, refactoring a tangled web controller, diagnosing fat controller or Template View scriptlet anti-patterns, mapping legacy JSP/ERB/ASP patterns to modern equivalents (Spring DispatcherServlet = Front Controller, Rails Router = Front Controller, JSP/ERB/Jinja = Template View), or deciding whether a wizard flow needs an Application Controller above a Front Controller. Applies to any language/framework: Java Spring MVC, Ruby on Rails, Python Django/Flask, ASP.NET Core, Node.js Express, PHP Laravel. Produces a web presentation design record with pattern selections, anti-p

magnus919 Bundle Semantic SpacetimeModel and analyze Semantic Spacetime (SST) graphs, distances, trajectories, drift, and model files. Do not use this skill for promise-theory vocabulary and fundamentals without SST modeling; use `promise-theory` for the substrate concepts.
-
magnus919 Bundle Workflow ArchitectDiscover your actual workflow through conversation or observation, then generate a tailored skills bundle that encodes it as loadable agent skills with trigger conditions. Use when you want to understand your own process, formalize it, or share it with collaborators. Also use when a session feels aimless — this skill gives it structure. Do not use this skill for unrelated requests; route to the nearest named specialist.
-
bookforge-ai Bundle Enterprise Architecture Pattern Stack SelectorSelect the right enterprise application architecture patterns for every layer of your system using Fowler's PEAA decision framework. Use this skill when designing or refactoring an enterprise app and asking: which domain-logic pattern should I use (Transaction Script, Domain Model, Table Module)? Which persistence pattern fits my stack (Active Record, Data Mapper, Table Data Gateway, Row Data Gateway)? Which web-presentation pattern applies (Front Controller, Page Controller, Template View)? How do I combine these into a coherent full-stack architecture? Triggers include: 'help me choose architecture patterns', 'which Fowler pattern for my app', 'enterprise application architecture', 'PEAA pattern selection', 'layer pattern selection', 'domain logic pattern vs persistence pattern', 'refactor enterprise app to patterns', 'how to structure a Spring/Django/Rails/ASP.NET app', 'what persistence pattern should I use', 'enterprise architecture decision', 'full-stack pattern stack', 'patterns of enterprise applicati

Triggers on requests about price elasticity, price sensitivity, demand curves, pricing optimization, or price-volume trade-offs.
-
lonsdale201 Skill Fluentcrm Companies ModelWork with FluentCRM 3.x Companies / account records from companion plugins. Covers the experimental company_module flag, FluentCrmApi('companies'), Company model fields, createOrUpdate, owner_id as Subscriber ID, custom company fields in meta.custom_values, primary company vs many-to-many company membership, attachContactsByIds / detachContactsByIds, company hooks, and company-aware contact filters. Use when a plugin must sync organizations/accounts, attach contacts to companies, read company segments, add automation company actions, or audit code touching fc_companies, company_id, attachCompanies, or fluent_crm/company_ hooks.
-
lonsdale201 Skill Lw Site Manager OverviewReference for the LW Site Manager plugin (lwplugins/ lw-site-manager) — a WP 6.9+ Abilities-API-native exposure layer that registers 120+ machine-callable abilities under the site-manager/* namespace for AI agents (Claude, ChatGPT, MCP clients) to discover and invoke. Covers updates / plugins / themes / posts / pages / comments / media / users / taxonomies / settings / backups / health / database / cache / WooCommerce. Calling pattern — REST run endpoint is /wp-json/wp-abilities/v1/abilities/{namespace}/{ability}/run with Application Password Basic auth. Important — this is NOT MainWP; the surface and security model are different (per-ability cap-checks via PermissionManager, not a single dashboard token). Header requires PHP 8.2 (not 8.1 as some docs say). Use when calling the plugin's abilities, advising on AI agent integration, or before extending the plugin (see lw-site-manager-extend-abilities). Triggers on site-manager/, lw-site-manager, wp-abilities/v1, AI agent + WP.

Use when the user mentions OKF, Open Knowledge Format, Google's knowledge format, LLM wiki bundles, agent knowledge packs, creating OKF bundles, validating OKF documents, or converting knowledge into the OKF standard. Do not use this skill for unrelated requests; route to the nearest named specialist.
-
magnus919 Bundle AI Operating EconomicsUse when deciding whether an AI-enabled workflow should be adopted, scaled, constrained, redesigned, or retired, and the decision must connect business outcomes, worker or user effects, quality guardrails, full operating cost, telemetry, uncertainty, and accountable governance. Do not use for a standalone financial model, infrastructure cost calculation, agent evaluation design, runtime operations, or general AI governance; route those details to the neighboring specialist skills.
-
prorise-cool Skill Agentic Identity Trust ArchitectDesigns identity, authentication, and trust verification systems for autonomous AI agents operating in multi-agent environments. Ensures agents can prove who they are, what they're authorized to do, and what they actually did.
-
magnus919 Bundle Actuarial Risk ModelingUse when analyzing, selecting, validating, or communicating models for insurance, actuarial, financial-risk, or other consequential uncertain outcomes. Covers regression, generalized linear models, frequency-severity, panel and longitudinal data, survival, time series, credibility, reserving, tail risk, calibration, and model governance. Do not use for generic software forecasting, ordinary SaaS financial models, or credentialed actuarial, investment, legal, or regulatory advice without the relevant specialist review.
-

lonsdale201 Skill Wp Rocket MCP And AbilitiesExpose, scope, or secure WP Rocket settings for AI / MCP clients — new in 3.23. Two layers — WP Abilities API abilities (wp-rocket/get-options readonly, wp-rocket/set-option destructive, category wp-rocket-options, cap rocket_manage_options) and a built-in MCP OAuth 2.1 server at /wp-json/mcp/mcp-oauth-server (/oauth/*, /.well-known) with trusted publisher Claude (claude.ai). Critical — abilities default ON (rocket_enable_abilities), the OAuth server defaults OFF (rocket_mcp_oauth_server_enabled), and both need the WP Abilities API + wordpress/mcp-adapter or nothing registers. Scope what AI may read / write via rocket_mcp_options_allowlist (an additive allowlist); add clients via rocket_mcp_trusted_publishers. Filters are typed (wpm_apply_filters_typed) — return exact bool / array. Use when exposing WP Rocket settings to an MCP client, scoping the allowlist, or reviewing AI-facing code. Triggers on rocket_mcp_, rocket_enable_abilities, wp-rocket/get-options, wp-rocket/set-option, "/oauth/" MCP server.
-
lonsdale201 Skill Jfb Action External APIHow to read submitted JetFormBuilder form data from a custom action, transform it (including %macro% replacement of admin-typed templates), call an external HTTP API, write the response back into the form context for downstream actions to use, and dispatch JFB events based on the API outcome. Use when building a custom action that integrates with a third-party service (LLM call, webhook, CRM, payment processor, geolocation lookup) and needs the action to behave as a node in a data-flow graph rather than a one-shot leaf. Triggers on mentions of "jet_fb_context", "update_request", "has_field", "get_value", "wp_remote_post" with form data, "macro replacement", or "API call from action".

lonsdale201 Skill Elementor Dynamic Tag Ajax SelectLet an Elementor control (in a Dynamic Tag or a widget) pick one item from a large dataset — products, posts, terms, users — without freezing the editor. A plain Controls_Manager::SELECT2 with options preloaded upfront (e.g. all 20k products) hangs the panel; the fix is Elementor Pro's AJAX query control — 'type' => QueryControlModule::QUERY_CONTROL_ID with an 'autocomplete' => [ 'object' => QUERY_OBJECT_POST|TAX|AUTHOR|USER|ATTACHMENT, 'query' => [...], 'display' => 'minimal'|'detailed' ] config. It is search-scoped server-side (no query runs until the user types), so catalog size is irrelevant. The query control is Pro-only, so feature-detect class_exists( QueryControlModule::class ) and degrade to a manual ID Controls_Manager::TEXT field when Pro is absent. Use when a tag/widget setting must reference a specific post/product, on large stores, or when the editor freezes opening a SELECT2.
-
lonsdale201 Bundle Fluentcart Extension ArchitectureDesigns and audits third-party FluentCart extensions against the real 1.6.0 bootstrap, hybrid WordPress-post/custom-table data model, monetary units, Free/Pro boundary, and public helper APIs.
