Guide users through a structured workflow for co-authoring documentation. Use when user wants to write documentation, proposals, technical specs, decision docs, or similar structured content. This workflow helps users efficiently transfer context, refine content through iteration, and verify the doc works for readers. Trigger when user mentions writing docs, creating proposals, drafting specs, or similar documentation tasks.
Create new skills, modify and improve existing skills, and measure skill performance. Use when users want to create a skill from scratch, update or optimize an existing skill, run evals to test a skill, benchmark skill performance with variance analysis, or optimize a skill's description for better triggering accuracy.
Register WordPress Abilities: machine-readable plugin operations with JSON Schema contracts, required permission callbacks, optional REST exposure, and AI/MCP-friendly discovery. Covers categories, wp_register_ability, WP_Ability::execute, REST run endpoints, meta.show_in_rest, annotations, and Ability vs REST route vs custom hook decisions. Use when exposing plugin functionality to agents, admin JS, external tools, or reviewing AI integration code.
Designs and reviews scheduled/background work in WordPress plugins: wp_schedule_event, wp_schedule_single_event, cron_schedules, wp_next_scheduled guards, activation scheduling, deactivation cleanup, WP-Cron pseudo-cron timing, DISABLE_WP_CRON/system cron, multisite per-blog cron, idempotent callbacks, chunking, and Action Scheduler graduation. Use when adding scheduled jobs, debugging late/duplicate cron events, or deciding between WP cron and Action Scheduler.
Design custom action/filter hooks emitted by a plugin: action vs filter semantics, prefixed names, docblocks, parameter stability, *_ref_array forwarding, and deprecated hook migration. Use when adding, reviewing, evolving, or deprecating a public hook surface. Triggers on do_action, apply_filters, apply_filters_deprecated, do_action_deprecated, apply_filters_ref_array, do_action_ref_array, did_action, did_filter, or hook @since docblocks.
Picks the right WordPress storage primitive for plugin data: options, user/post/term/comment meta, transients, site options, site transients, or custom tables. Covers grouped settings, autoload management, transient TTL rules, serialized/JSON blob trade-offs, multisite storage caveats, and naming conventions. Use when scaffolding settings, choosing persistence for plugin-owned data, or auditing update_option/get_option/get_post_meta/set_transient/autoload usage.
Design and review custom WordPress URL rewrites: add_rewrite_rule, add_rewrite_tag, query_vars, CPT/taxonomy rewrite slugs, add_rewrite_endpoint, soft vs hard flushes, rewrite_rules cache behavior, and the rule that flush_rewrite_rules() must not run on every request. Use for custom pretty URLs, CPT permalink 404s, endpoint rewrites, and code containing flush_rewrite_rules or add_rewrite_rule.
Design and review Action Scheduler jobs in WordPress plugins using Action Scheduler 3.9.x public APIs - async, single, recurring, and cron-expression actions; action_scheduler_init load timing; hook/args/group naming; unique and priority parameters; idempotent callbacks; chunked workloads; activation/deactivation cleanup; WooCommerce-bundled or standalone dependency usage; admin and WP-CLI debugging; queue runner limits; and safe operational troubleshooting. Use when a plugin schedules background jobs with as_enqueue_async_action, as_schedule_single_action, as_schedule_recurring_action, as_schedule_cron_action, as_get_scheduled_actions, or integrates with WooCommerce background queues.
