## What it 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`.

## Requirements
- Works with: PostgreSQL

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add parcadei/Continuous-Claude-v3 --skill system-overview -a claude-code
```
```bash
npx skills add parcadei/Continuous-Claude-v3 --skill system_overview -a claude-code
```

2. **Manually: put the files in place**
- File: `~/.claude/skills/system_overview/SKILL.md` — Copy the whole skill folder; for one project use .claude/skills/system_overview/

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add parcadei/Continuous-Claude-v3 --skill system_overview -a codex
```

2. **Manually: put the files in place**
- File: `.agents/skills/system_overview/SKILL.md` — For all projects use ~/.agents/skills/

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add parcadei/Continuous-Claude-v3 --skill system_overview -a cursor
```

2. **Manually: put the files in place**
- File: `.cursor/skills/system_overview/SKILL.md` — Cursor also reads .agents/skills/ and .claude/skills/

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install parcadei/Continuous-Claude-v3 system_overview
```

2. **Manually: put the files in place**
- File: `.github/skills/system_overview/SKILL.md`

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add parcadei/Continuous-Claude-v3 --skill system_overview -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/parcadei/Continuous-Claude-v3 --path .claude/skills/system_overview
```

### Windsurf (Devin Desktop)

**Manually: put the files in place**
- File: `.devin/skills/system_overview/SKILL.md` — The legacy .windsurf/skills/ path still works

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add parcadei/Continuous-Claude-v3 --skill system_overview -a opencode
```

### Claude.ai

**Claude.ai**
- Zip the folder and upload it in Settings → Capabilities → Skills

Where a file is given instead of a command, copy the files from the source to that path: https://github.com/parcadei/Continuous-Claude-v3/tree/HEAD/.claude/skills/system_overview/SKILL.md

## When to use it
- 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
- /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)
```
