system-overview — Claude Code skill: what it does, how to install
Displays the Continuous Claude architecture, showing memory layers, 9 registered hook types, and session continuity mechanisms.
npx skills add parcadei/Continuous-Claude-v3 --skill system-overview -a claude-code
npx skills add parcadei/Continuous-Claude-v3 --skill system_overview -a claude-codeWhat system-overview does
The system-overview skill outputs an overview of the Continuous Claude environment whenever a user asks how the setup works or runs /system_overview. It reports the active components managing long-term memory, automated handoffs, and code intelligence tooling.
The memory layer tracks 78,000+ temporal facts using either SQLite or PostgreSQL with pgvector for semantic search. A 9-hook pipeline manages the session lifecycle. It intercepts Grep calls for .py, .ts, .go, and .rs files and saves state before context compaction. Code analysis relies on a 5-layer TLDR pipeline from AST to PDG, cutting token usage by 95% compared to raw file reads.
Running the full semantic setup requires Python managed via uv and setting CONTINUOUS_CLAUDE_DB_URL, while optional embeddings need VOYAGE_API_KEY.
What it helps with
- inspect the Continuous Claude runtime architecture
- check registered hooks across the agent session lifecycle
- verify memory settings and temporal fact retrieval
- locate handoff files and ledger paths between sessions
Example prompts for the agent
- /system_overview
- how does this work?
- what's different about this setup?

# System Overview
Show users how Continuous Claude works - the opinionated setup with hooks, memory, and coordination.
## When to Use
- User asks "how does this work?"
- User asks "what can you remember?"
- User asks "what's different about this setup?"
- User runs `/system_overview`
## Response
```
CONTINUOUS CLAUDE SYSTEM OVERVIEW
=================================
MEMORY LAYER (PostgreSQL + pgvector)
------------------------------------
- 78,000+ temporal facts from past sessions
- Learnings extracted automatically at session end
- Semantic search with embeddings
RECALL: uv run python opc/scripts/recall_temporal_facts.py --query "your topic"
HOOKS (9 event types registered)
--------------------------------
SessionStart → Load continuity ledger, rebuild symbol index
UserPromptSubmit → Skill activation check, context injection
PreToolUse → Smart search routing (Grep → TLDR for code)
PostToolUse → File claims, compiler feedback
PreCompact → Save state before context compaction
Stop → Extract learnings, create handoffs
SubagentStart → Register spawned agents
SubagentStop → Coordination, handoff creation
SessionEnd → Cleanup
CONTINUITY SYSTEM
-----------------
Ledger: thoughts/ledgers/CONTINUITY_CLAUDE-{session}.md
Handoffs: thoughts/shared/handoffs/{session}/*.yaml
Commands:
/resume_handoff <path> - Continue from handoff
/create_handoff - Create snapshot for transfer
TLDR CODE INTELLIGENCE
----------------------
5-layer analysis: AST → Call Graph → CFG → DFG → PDG
95% token savings vs reading raw files
Auto-intercepts Grep for .py/.ts/.go/.rs files
Pre-built index: /tmp/claude-symbol-index/symbols.json
SETUP
-----
Run: uv run python opc/scripts/setup/wizard.py
Options:
[1] SQLite only (simple, offline)
[2] PostgreSQL + pgvector (semantic search)
```
