"Every session leaves a Starlight Fragment. Enough fragments form a constellation."
The Starlight Vault is Arcanea's continuous learning system. It observes your creative patterns, captures them as Starlight Fragments (atomic learned behaviors), and evolves them into constellations of reusable knowledge.
| Arcanean Term | Technical Term | Description |
|---|---|---|
| Starlight Fragment | Instinct | One trigger → one action, confidence-weighted |
| Constellation | Evolved Skill | Cluster of related fragments that form a skill |
| Starlight Vault | Instinct Store | Per-project + global storage |
| Fragment Gathering | Observation | Captured tool use events |
| Crystallization | Promotion | Fragment proven across 2+ projects → global |
Fragments are stored as YAML files with frontmatter:
---
id: prefer-server-components
trigger: "when creating new React components"
confidence: 0.7
domain: "code-style"
source: "session-observation"
scope: project
project_id: "arcanea-web"
project_name: "Arcanea"

# Prefer Server Components
## Action
Use Server Components by default. Only add 'use client' when state or effects are needed.
## Evidence
- Observed 8 instances of server-first pattern
- User corrected client component to server on 2026-03-10
| Observations | Confidence | Level |
|---|---|---|
| 1-2 | 0.3 | Tentative (dim fragment) |
| 3-5 | 0.5 | Moderate (glowing fragment) |
| 6-10 | 0.7 | Strong (bright fragment) |
| 11+ | 0.85 | Very strong (radiant fragment) |

/instinct-status — Show all fragments with confidence levels/instinct-export — Export fragments for sharing/instinct-import — Import fragments from another vaultThe Starlight Vault connects to Arcanea's SIS memory layer. Fragments with confidence >= 0.8 are automatically surfaced in relevant sessions.
npx claudepluginhub frankxai/arcanea-records --plugin arcaneaThree-tier learning system that captures instincts (hypotheses), user corrections (permanent rules), and discoveries (insights) per project. Routes signals to the right store, manages confidence scoring, and supports export/import between projects.
Observes Claude Code sessions to extract atomic 'instincts' (behaviors with confidence scoring), evolving them into reusable skills/commands/agents. Adds project-scoped instincts in v2.1 to prevent cross-project contamination.
Instinct-based learning system that turns Claude Code sessions into atomic, confidence-scored behaviors that can evolve into skills, commands, or agents. V2.1 adds project-scoped instincts to prevent cross-project contamination.
