Detect structural macro regime transitions (1-2 year horizon) using cross-asset ratio analysis. Analyze RSP/SPY concentration, yield curve, credit conditions, size factor, equity-bond relationship, and sector rotation to identify regime shifts between Concentration, Broadening, Contraction, Inflationary, and Transitional states. Run when user asks about macro regime, market regime change, structural rotation, or long-term market positioning.

Use BEFORE editing any file in `supabase/migrations/` or `supabase/schemas/`, OR when the user runs a `/database` subcommand (`compact local migration`, `rls scenarios`, `align`). Encodes the three contracts that protect the Grida database layer: applied migrations are immutable, RLS implementation mirrors tests (never the reverse), `schemas/*.sql` is the human-readable end-state. Companion to `supabase/AGENTS.md` (RLS, grants, security boundaries).

Stereo depth estimation using FoundationStereo. Predicts disparity maps from stereo image pairs for 3D reconstruction. Use when training, evaluating, exporting, or running inference for a TAO FoundationStereo model. Trigger phrases include "train stereo depth", "FoundationStereo", "stereo disparity estimation", "3D reconstruction from stereo".

Real-time stereo depth estimation using FastFoundationStereo (FFS), the distilled bp2 commercial variant of FoundationStereo. Predicts disparity maps from stereo image pairs with ~10× lower latency than full FoundationStereo. Use when training, evaluating, exporting, or running inference for a TAO FastFoundationStereo (FFS) model. Trigger phrases include "train fast stereo", "real-time stereo disparity", "FastFoundationStereo", "distilled stereo depth".

Ingest new documents, raw text, folders, or URLs into the Obsidian wiki as distilled, linked knowledge. Use for general wiki ingestion when no more specific ingest skill applies, including processing _raw/ staged content.

Ingest Hermes agent history into Obsidian as distilled knowledge. Use for importing or mining ~/.hermes sessions, memories, or logs; use wiki-agent for targeted topic-only cross-agent recall.

How to work in a Worldbuilding project (the `worldbuilding` starter pack): a fiction encyclopedia of characters, settings, themes, factions, and lore. Read when the project has these folders, OR when asked to add a character, setting, faction, or piece of lore, or to check the world for internal consistency. Carries the auto-stub and consistency behaviors so that guidance does not live inside template bodies or folder descriptions. Complements the platform `open-knowledge` skill; does not replace it.

Promote existing research into a stable-status canonical article under `articles/` in a Knowledge Base project (the `knowledge-base` starter pack). Read when a decision has actually been made and the team wants the source-of-truth written down, or when asked to consolidate, canonicalize, promote research, or supersede an older article. Carries the decision-confirmation gate, the `supersedes:` chain that keeps the evidence trail intact, and the canonical voice. Does not conduct new research — that is the sibling `research-with-sources` skill.

Format code on the current branch using Biome. Use when asked to format, lint, or clean up code before committing or creating a PR.

Read before adding or changing any front/ UI element - a control, layout, button, or interaction pattern. Covers the don't-invent-new-UX-without-a-PRD rule and the priority order for design tradeoffs (existing behavior > intuitiveness > information density > usability > utility > uniqueness > industry practices > generic UI).

Explore and understand Nx workspaces. USE WHEN answering questions about the workspace, projects, or tasks. ALSO USE WHEN an nx command fails or you need to check available targets/configuration before running a task. EXAMPLES: 'What projects are in this workspace?', 'How is project X configured?', 'What depends on library Y?', 'What targets can I run?', 'Cannot find configuration for task', 'debug nx task failure'.

Query the live Unity scene (GameObjects, components, assets) with RQL in ONE call: filter, project, sort, count, walk hierarchies. Far fewer calls/tokens than reading objects one by one.

Use CodeGraphContext (CGC) to index a repo into a graph DB and query it via CLI or MCP. Apply when the user wants semantic/code-graph search, call graphs, indexing, or configuring the codegraphcontext MCP server.

Split oversized FLA pull requests into focused changes, reuse existing PRs, and create or maintain verified GitHub native PR stacks.

把概念、公式、机制与原理讲到能辨认、能推导、能迁移：用通俗中文接通具体情境、判别依据、运作过程和成立条件。USE WHEN 用户调用 ljg-explain、说「通俗易懂地讲解」「讲透这个概念或公式」「费曼讲解」「ELI5」，或希望从零理解一个知识点并能用于新情境。NOT FOR 单纯润色或翻译、整篇伴读、整本书或论文解读、只要求形式证明或操作步骤。

Initialize Trellis AI workflow system in a project. Use when user mentions "Trellis", "初始化 Trellis", "setup Trellis", "install Trellis", or wants to add AI-assisted development workflow to their project. This is a one-time setup skill.

Review EF Core pull requests or local changes for concrete correctness, compatibility, performance, security, and test-coverage problems. Use when asked to review, critique, or check code changes before merge or submission.

Cut an OpenWork release, release the app, publish a new version, rerun or recover a release tag, verify release assets. Tag-driven GitHub Actions release that makes zero commits to the repo.

Use this skill when `biome migrate eslint` must preserve configurable ESLint rule options through source-option models, Biome conversions, typed rule variants, and migration fixtures. Do not use for generated severity-only mapping or general rule-option design.

Recall and persist long-term memory through the OpenViking MCP tools. Use at the start of any substantive task (coding, configuration, debugging, multi-step or tool-based work) to retrieve relevant prior knowledge with find/search/read, and during or after work to persist durable facts, preferences, decisions, and lessons with remember. Do not use for casual chat or simple factual questions the model can answer directly.
