Layer 1 — Domain Foundation
Universal mobile development principles that apply to every mobile project regardless of framework. React Native, Flutter, Swift, Kotlin — these hold.
Mobile is not "web on a small screen." The constraints are fundamentally different: unreliable networks, limited battery, touch as primary input, platform-specific user expectations, background/foreground lifecycle, and physical device variations from $80 phones to $1500 flagships.
This pack encodes the mobile-specific principles that agents consistently miss when applying web-first thinking to mobile development.
| Type | Files | Coverage | |------|-------|----------| | Patterns | 7 | Offline-first, performance/60fps, touch & gestures, navigation, lifecycle, responsive layout, platform conventions | | Anti-patterns | 5 | Web-first thinking, blocking main thread, ignoring lifecycle, hardcoded dimensions, permission spam | | Constitution | 1 | 6 non-negotiable mobile principles |
react-native, flutter)backend)tools
Captures agent mistakes, corrections, and discovered gotchas so they are not repeated. Use when: (1) a command or operation fails unexpectedly, (2) the user corrects the agent, (3) the agent discovers non-obvious behavior through debugging, (4) an API or tool behaves differently than expected, (5) a better approach is found for a recurring task. Also searches past learnings before starting tasks to avoid known pitfalls. Activate alongside the sage-memory skill — they share the same MCP backend but serve different purposes (sage-memory = codebase knowledge, sage-self-learning = agent mistakes and gotchas).
development
Typed knowledge graph stored in sage-memory. Use when creating or querying structured entities (Person, Project, Task, Event, Document), linking related objects, checking dependencies, planning multi-step actions as graph transformations, or when skills need to share structured state. Trigger on "remember that X is Y", "what do I know about", "link X to Y", "show dependencies", "what blocks X", entity CRUD, cross-skill data access, or any request involving structured relationships between things.
tools
Integrates sage-memory into Sage workflows. Teaches the agent when to remember (store findings during work), when to recall (search memory at session start and task start), and how to learn (structured knowledge capture via sage learn). Use when the user mentions memory, remember, recall, learn, capture knowledge, onboard to codebase, or when starting any session where sage-memory MCP tools are available.
