## What it does

The skill lays out a decision tree keyed to query type. For code exploration — symbols, call chains, data flow — it points to `tldr search "query" .` and marks that as the default instead of Grep. Structural patterns like `def foo`, `class Bar` or `import X` go to `/ast-grep-find`; conceptual questions go to `tldr semantic search "query"`; Grep is left as a last resort for exact text and regex.

Inside there is a token-cost table plus command examples. TLDR returns roughly 50–500 tokens, AST-grep about 50, Grep 200 to 2000, and Read 1500 or more. That ordering drives the suggested flow: find matches first, open only the top hit, skip the rest.

The skill is marked `user-invocable: false`, so you cannot call it yourself — it acts as guidance the agent reads. The commands in the tree only pay off if `tldr` and `/ast-grep-find` are actually available on your machine; otherwise you are left with advice and nothing to run. Worth adding when searching a large repo is already eating your context.

## Install

### Claude Code (native platform)

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

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

### Codex

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

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

### Cursor

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

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

### GitHub Copilot

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

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

### Gemini CLI

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

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

### Windsurf (Devin Desktop)

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

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add parcadei/Continuous-Claude-v3 --skill search-router -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/search-router/SKILL.md

## When to use it
- locate where a symbol is defined without reading whole files
- trace a call chain and data flow
- pull out functions and classes by AST pattern
- ask how authentication works in plain words
- cut token spend while exploring an unfamiliar repo

## Example prompts
- find where spawn_agent is used, use tldr
- list every async def in the project with ast-grep
- how is error handling done here? search semantically

# Search Tool Router

Use the most token-efficient search tool for each query type.

## When to Use

- Searching for code patterns
- Finding where something is implemented
- Looking for specific identifiers
- Understanding how code works

## Decision Tree

```
Query Type?
├── CODE EXPLORATION (symbols, call chains, data flow)
│   → TLDR Search - 95% token savings
│   DEFAULT FOR ALL CODE SEARCH - use instead of Grep
│   Examples: "spawn_agent", "DataPoller", "redis usage"
│   Command: tldr search "query" .
│
├── STRUCTURAL (AST patterns)
│   → AST-grep (/ast-grep-find) - ~50 tokens output
│   Examples: "def foo", "class Bar", "import X", "@decorator"
│
├── SEMANTIC (conceptual questions)
│   → TLDR Semantic - 5-layer embeddings (P6)
│   Examples: "how does auth work", "find error handling patterns"
│   Command: tldr semantic search "query"
│
├── LITERAL (exact text, regex)
│   → Grep tool - LAST RESORT
│   Only when TLDR/AST-grep don't apply
│   Examples: error messages, config values, non-code text
│
└── FULL CONTEXT (need complete understanding)
    → Read tool - 1500+ tokens
    Last resort after finding the right file
```

## Token Efficiency Comparison

| Tool | Output Size | Best For |
|------|-------------|----------|
| **TLDR** | **~50-500** | **DEFAULT: Code symbols, call graphs, data flow** |
| **TLDR Semantic** | **~100-300** | **Conceptual queries (P6, embedding-based)** |
| AST-grep | ~50 tokens | Function/class definitions, imports, decorators |
| Grep | ~200-2000 | LAST RESORT: Non-code text, regex |
| Read | ~1500+ | Full understanding after finding the file |

## Examples

```bash
# CODE EXPLORATION → TLDR (DEFAULT)
tldr search "spawn_agent" .
tldr search "redis" . --layer call_graph

# STRUCTURAL → AST-grep
/ast-grep-find "async def $FUNC($$$):" --lang python

# SEMANTIC → TLDR Semantic
tldr semantic search "how does authentication work"

# LITERAL → Grep (LAST RESORT - prefer TLDR)
Grep pattern="check_evocation" path=opc/scripts

# FULL CONTEXT → Read (after finding file)
Read file_path=opc/scripts/z3_erotetic.py
```

## Optimal Flow

```
1. AST-grep: "Find async functions" → 3 file:line matches
2. Read: Top match only → Full understanding
3. Skip: 4 irrelevant files → 6000 tokens saved
```
