An interactive guide for changing MatClaw, a messaging-based assistant. It covers adding input channels, changing triggers, adding integrations, and modifying how messages are routed.

Use it to add channels such as Telegram, Slack, or email, change trigger words, or modify MatClaw’s integrations and behavior. It asks questions before implementation so the change matches the intended setup.

It helps turn a broad customization request into a concrete set of code changes. It also points to the files responsible for channels, routing, configuration, storage, and message processing.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Model	Per session	Once invoked
Fable 5	$0.00060	$0.00938
Opus 5	$0.00030	$0.00469

Security

Grade A, and why

customize scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Origin

This is a copy

92% identical to customize — 12 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

MatClaw Customization

This skill helps users add capabilities or modify behavior. Use AskUserQuestion to understand what they want before making changes.

Workflow

Understand the request - Ask clarifying questions
Plan the changes - Identify files to modify
Implement - Make changes directly to the code
Test guidance - Tell user how to verify

Key Files

File	Purpose
`src/index.ts`	Orchestrator: state, message loop, agent invocation
`src/channels/whatsapp.ts`	WhatsApp connection, auth, send/receive
`src/ipc.ts`	IPC watcher and task processing
`src/router.ts`	Message formatting and outbound routing
`src/types.ts`	TypeScript interfaces (includes Channel)
`src/config.ts`	Assistant name, trigger pattern, directories
`src/db.ts`	Database initialization and queries
`src/whatsapp-auth.ts`	Standalone WhatsApp authentication script
`groups/CLAUDE.md`	Global memory/persona

Common Customization Patterns

Adding a New Input Channel (e.g., Telegram, Slack, Email)

Questions to ask:

Which channel? (Telegram, Slack, Discord, email, SMS, etc.)
Same trigger word or different?
Same memory hierarchy or separate?
Should messages from this channel go to existing groups or new ones?

Implementation pattern:

Create src/channels/{name}.ts implementing the Channel interface from src/types.ts (see src/channels/whatsapp.ts for reference)
Add the channel instance to main() in src/index.ts and wire callbacks (onMessage, onChatMetadata)
Messages are stored via the onMessage callback; routing is automatic via ownsJid()

Adding a New MCP Integration

Questions to ask:

What service? (Calendar, Notion, database, etc.)
What operations needed? (read, write, both)
Which groups should have access?

Implementation:

Add MCP server config to the container settings (see src/container-runner.ts for how MCP servers are mounted)
Document available tools in groups/CLAUDE.md

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

customize is a skill published in the GitHub repository DingyangLyu/MatClaw (89 stars, last pushed 4mo ago), licensed Apache-2.0. It adds 60 tokens to every session and 938 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it A with 0 findings. It is 92% identical to customize, differing in 12 lines, and is treated as a copy.
