## What it does

Claude's `/resume` picker matches on conversation names. This plugin opens the actual content of each message, tool call and tool result, so MCP responses, web searches and command output are searchable too. That is how you track down the session where a particular API or decision came up.

Plain text and regex patterns both work, and you can widen the snippet shown around each hit. Conversations are ranked by match count, and each one comes with a UUID you can hand straight to `claude --resume`. The script relies on Node.js built-ins alone and never writes to your conversation files.

Conversations live as `.jsonl` files under `~/.claude/projects/`. The script parses every line, so a single query covers all your projects. Installing through the marketplace needs a Claude restart — the `/chat-search` command will not show up without one.

## Install

### Claude Code (native platform)

**Plugin marketplace**
In the agent chat (not a shell):
```text
/plugin marketplace add anthropics/claude-plugins-community
```
In the agent chat (not a shell):
```text
/plugin install claude-chat-search@claude-community
```

## When to use it
- find the session where a specific library was discussed
- pull an MCP server response out of an old conversation
- locate every mention of an error with a regex
- grab a conversation UUID for `claude --resume`
- see which commands ran in earlier projects

## Example prompts
- /chat-search supabase
- /chat-search supabase.*auth --regex
- /chat-search migration --context 80

# Claude Chat Search

Full-text search across all your Claude Code conversations.

Claude Code's built-in `/resume` picker searches by conversation name only. This plugin searches through the **actual content** of every message, tool call, and tool result in every conversation — so you can find that one session where you discussed a specific topic, API, or decision.

## What it does

- Searches through all `.jsonl` conversation files across all projects
- Searches user messages, assistant messages, **and tool results** (MCP outputs, web searches, etc.)
- Supports plain text search and **regex patterns**
- Configurable context window for match snippets
- Shows matching conversations ranked by number of matches
- Provides UUIDs for easy `claude --resume` access
- Zero dependencies — just Node.js built-ins

## Install

### As a Claude Code plugin (recommended)

```bash
claude plugin install --source https://github.com/danutmitrut/claude-chat-search.git
```

Then restart Claude Code. The `/chat-search` command will be available.

### Manual install via Claude Code

Open Claude Code in VS Code and paste this as a single message:

```
Install the chat-search tool. Follow these steps exactly:

1. Clone the repo:
git clone https://github.com/danutmitrut/claude-chat-search.git /tmp/claude-chat-search

2. Copy the search script:
mkdir -p ~/.claude/tools
cp /tmp/claude-chat-search/scripts/chat-search.js ~/.claude/tools/chat-search.js

3. Create the command file ~/.claude/commands/chat-search.md with this content:

---
description: Full-text search across all Claude Code conversations
---

Search through the full content of all Claude Code conversations (not just titles/names).

Run:
node ~/.claude/tools/chat-search.js $ARGUMENTS

If no arguments provided, ask the user what they want to search for.

Present results clearly:
- Conversation title, match count, date, message count
- Top 3 relevant snippets per conversation
- UUID for resume (offer claude --resume <uuid> if the user wants to resume one)

4. Clean up: rm -rf /tmp/claude-chat-search

5. Test it: run /chat-search supabase (or any keyword relevant to you)
```

## Usage

After install, restart Claude Code (or `/clear`), then use:

```
/chat-search supabase
/chat-search landing page
/chat-search auth middleware
```

### Regex search

Use `--regex` (or `-r`) to search with regex patterns:

```
/chat-search supabase.*auth --regex
/chat-search error.*404 -r
```

### Custom context window

Use `--context N` (or `-c N`) to control how many characters are shown around each match (default: 40):

```
/chat-search deploy --context 80
/chat-search migration -c 100
```

### Combined

```
/chat-search supabase.*rls --regex --context 80
```

## Example output

```
"supabase.*auth" (regex) — 12 conversation(s) found

1. [224 matches] Built reservation form with database integration
   2/25/2026 | 7262 msgs | 5f9f961a...
   > [assistant] msg #13: ...configured Supabase real (credentials + table)...
   > [tool] msg #103: ...POST "https://xyz.supabase.co/rest/v1/rpc" -H "apikey:...
   > [tool] msg #105: ...POST "https://api.supabase.com/v1/projects/xyz/database...

2. [64 matches] Explored ccforeveryone.com tools
   2/22/2026 | 2112 msgs | 9f21a9ba...
   > [assistant] msg #207: ...Context7, Playwright, Supabase, GitHub configured...
```

Note: `[tool]` results are included in search — this catches MCP outputs, web searches, command results, and other tool interactions that the built-in search misses entirely.

## How it works

Claude Code stores conversations as `.jsonl` files in `~/.claude/projects/`. Each line is a JSON object containing messages. The script reads every file, parses every message (including tool use and tool results), and searches through the text content.

It's read-only — never modifies your conversation files.
