Executable form of model-tiering-convention: five pre-tiered subagents with model + effort + tool scope declared in frontmatter. Triggers whenever work can be delegated instead of done on the main Opus thread — reconnaissance, summarisation, mechanical implementation, review. Ships explorer (haiku/low, read-only), summariser (haiku/low, read-only), implementer (sonnet/medium), code-reviewer (sonnet/medium, no writes), security-reviewer (opus/high, no writes). Tiering becomes mechanical instead of advisory.
5 agents
Three-lane parallel execution pattern for the Orryx Group (Brain + Triora + Pillarworks lanes coordinated by SYNC_STATE + CONTROL_STATE). Triggers on cross-product Sprint planning, "what should each product team do this sprint", "coordinate the lanes", or "/3-lane-parallel". Originally Brain Sprint 28 pattern; promoted to cross-cutting.
1 skill
Multi-agent collaboration patterns + agent roles + swarming protocols + cross-model verification for Orryx Group development. Triggers on multi-agent task design, "spawn agents", "parallelise this work", or planning a complex delivery. Canonical Orryx pattern; lifted from Triora.
1 skill
Check-before-create discipline. Triggers before authoring a new skill, agent, prompt, slash command, hook, or shared schema. Consults the repo-local ASSET_INDEX.md to prevent duplication; lifted from Pillarworks's mature pattern. Reduces "we already have one of these" rework and keeps cross-product coordination cheaper.
1 skill
BMAD planning workflow (Brief, Model, Architect, Develop). Triggers on greenfield feature work, product discovery, or "let's design X". Produces a PRD and Tech Spec before any implementation. Pattern adopted by Pillarworks from bmad-code-org; promoted to Orryx cross-cutting.
1 skill
Two-stage code review (sonnet then opus for high-risk) with skill + subagent + slash-command surfaces. Triggers on review requests, pre-merge checks, "review this PR / diff / branch", or as the final step of plan-and-execute. Merges Triora code-reviewer + merge-review, Pillarworks review SKILL + reviewer + quality-gate agents, and Brain /review command.
