Channel Formatting

This skill wires channel-aware Markdown conversion into the outbound pipeline so Claude's responses render natively on each platform — no more literal **asterisks** in WhatsApp or Telegram.

Code blocks (fenced and inline) are always protected — their content is never transformed.

Phase 1: Pre-flight

Check if already applied

test -f src/text-styles.ts && echo "already applied" || echo "not yet applied"

If already applied, skip to Phase 3 (Verify).

Phase 2: Apply Code Changes

Ensure the upstream remote

git remote -v

If an upstream remote pointing to https://github.com/qwibitai/nanoclaw.git is missing, add it:

git remote add upstream https://github.com/qwibitai/nanoclaw.git

Merge the skill branch

git fetch upstream skill/channel-formatting
git merge upstream/skill/channel-formatting

If there are merge conflicts on package-lock.json, resolve them by accepting the incoming version and continuing:

git checkout --theirs package-lock.json
git add package-lock.json
git merge --continue

For any other conflict, read the conflicted file and reconcile both sides manually.

This merge adds:

• src/text-styles.ts — parseTextStyles(text, channel) for marker substitution and parseSignalStyles(text) for Signal native rich text
• src/router.ts — formatOutbound gains an optional channel parameter; when provided it calls parseTextStyles after stripping <internal> tags
• src/index.ts — both outbound sendMessage paths pass channel.name to formatOutbound
• src/formatting.test.ts — test coverage for both functions across all channels

Validate

npm install
npm run build
npx vitest run src/formatting.test.ts

All 73 tests should pass and the build should be clean before continuing.

Phase 3: Verify

Rebuild and restart

npm run build
launchctl kickstart -k gui/$(id -u)/com.nanoclaw   # macOS
# Linux: systemctl --user restart nanoclaw

Spot-check formatting

Send a message through any registered WhatsApp or Telegram chat that will trigger a response from Claude. Ask something that will produce formatted output, such as:

Summarise the three main advantages of TypeScript using bullet points and bold headings.

Confirm that the response arrives with native bold (*text*) rather than raw double asterisks.

Check logs if needed

tail -f logs/nanoclaw.log

Signal Skill Integration

If you have the Signal skill installed, src/channels/signal.ts can import parseSignalStyles from the newly present src/text-styles.ts:

import { parseSignalStyles, SignalTextStyle } from '../text-styles.js';

parseSignalStyles returns { text: string, textStyle: SignalTextStyle[] } where textStyle is an array of { style, start, length } objects suitable for the signal-cli JSON-RPC textStyles parameter (format: "start:length:STYLE").

Removal

# Remove the new file
rm src/text-styles.ts

# Revert router.ts to remove the channel param
git diff upstream/main src/router.ts   # review changes
git checkout upstream/main -- src/router.ts

# Revert the index.ts sendMessage call sites to plain formatOutbound(rawText)
# (edit manually or: git checkout upstream/main -- src/index.ts)

npm run build
