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
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.
1 skill
Continuous Parallel Development (CPD) protocol with 5 parallel work streams (Research, Discovery, Planning, Development, Review). Triggers on Sprint planning, "run in parallel", "parallelise the work", or "what should each lane do". Defines mandatory parallel agents per sprint start, execution patterns, and research queue management. Lifted from Triora.
