Fable Loop orchestrates a task through planning, execution, and adversarial verification using parallel subagents. Use it for non-trivial multi-step tasks when the user invokes '/fable-loop' or asks for work done in the style of Fable.

Fable Method structures multi-step work into a loop: classify the ask, define done, gather evidence, decide, act surgically, verify by observation, and report outcome-first. Use when the user says "/fable-method", "use the fable method", or "approach this like Fable", or proactively when starting any multi-step task no task-specific skill covers. Supports plan, audit, and report subcommands.

Agents Best Practices provides a provider-neutral framework for designing, building, auditing, and refining agentic harnesses across domains. Use it when creating MVP agent blueprints, tool permissions, context/memory, observability, evals, and safety controls for OpenAI, Anthropic, or compatible APIs.

Capability Catalog lists the temporal date-range skills and external integrations available to a spawned worker and exactly how to call each. Use it at boot or whenever unsure what tools or integrations you have.

Last 30 Days resolves a rolling 30-day window ending today to concrete ISO date ranges, including UTC instants, so agents have accurate temporal bounds without manual date math. Use it before any 'last 30 days' or trailing-month task like monthly trends or recent activity.

Last 7 Days resolves 'last7Days' to a concrete inclusive date range and exact UTC instants for a rolling 7-day window ending today. Use it before any 'last 7 days' or trailing-week task to get temporal bounds without computing dates by hand.

Last Year resolves the previous full calendar year to a concrete ISO date range with inclusive civil dates and exact UTC instants. Use it before tasks over last year, such as annual reports or year-over-year comparisons.

MD Hive Sync runs the start-of-task hive protocol steps: reads memory.md, checks inbox/ for new messages, and reminds you to record durable facts in memory.md and write coordination files before ending. Use when asked to sync with the hive, check inbox, hive status, or hive sync.

Temporal resolves named time windows like today, yesterday, last30Days, thisQuarter, or last12Months to concrete ISO date ranges relative to the current run time. Use it when a task is time-scoped and you need exact start and end dates without computing them manually.

This Week resolves 'thisWeek' to a concrete ISO date range relative to your run time, covering this week so far (Monday → today). Use it before week-to-date tasks like weekly standups or this week's activity reports.

Yesterday resolves 'yesterday' to a concrete ISO date range relative to run time, returning inclusive civil dates and exact UTC instants. Use it before tasks scoped to yesterday, such as daily reports or change summaries.

Architecture Workflow guides AI agents through adaptive project onboarding questions and recommends a tailored sequence of /arckit:* commands for enterprise architecture governance. Use it when starting a project, checking what to run next, or needing a sector- and stage-specific plan.
