+name: add-transcription
+description: Add voice transcription support to NanoClaw. Channel-agnostic — works with any channel that provides audio buffers. Supports local whisper.cpp or OpenAI Whisper API.
+---
+
+# Add Transcription
+
+Adds a channel-agnostic voice transcription module (`src/transcription.ts`). Any channel skill (Telegram, WhatsApp, Discord, etc.) can dynamically import this module to transcribe voice messages.
+
+Two backends are supported:
+- **Local** (default): Uses `whisper-cli` (whisper.cpp) + `ffmpeg`. No API key, no network, no cost.
+- **API**: Uses OpenAI Whisper API. Requires `OPENAI_API_KEY`.
+
+## Phase 1: Pre-flight
+
+### Check if already applied
+
+```bash
+grep 'export async function transcribe' src/transcription.ts && echo "Already applied" || echo "Not applied"
+```
+
+If already applied, skip to Phase 3 (Verify).
+
+### Ask which backend
+
+Ask the user which transcription backend they want:
+
+1. **Local (whisper.cpp)** — free, private, requires ffmpeg + whisper-cli + model download
+2. **OpenAI Whisper API** — easy setup, requires API key, sends audio to OpenAI
+
+Default to local if the user has no preference.
+
+## Phase 2: Apply Code Changes
+
+### Merge the skill branch
+
+```bash
+git remote add transcribe https://github.com/kky/nanoclaw-transcribe.git
+git fetch transcribe skill/transcribe
+git merge transcribe/skill/transcribe || {
+  git checkout --theirs package-lock.json
+  git add package-lock.json
+  git merge --continue
+}
+```
+
+### Validate
+
+```bash
+npm run build
+```
+
+## Phase 3: Install Dependencies
+
+### For local backend
+
+#### Install ffmpeg
+
+- **macOS**: `brew install ffmpeg`
+- **Linux**: `sudo apt install ffmpeg`
+
+#### Install whisper.cpp
+
+- **macOS**: `brew install whisper-cpp` (provides `whisper-cli`)
+- **Linux**: Build from source:
+  ```bash
+  cd /tmp && git clone --depth 1 https://github.com/ggerganov/whisper.cpp.git
+  cd whisper.cpp && cmake -B build && cmake --build build -j$(nproc)
+  sudo cp build/bin/whisper-cli /usr/local/bin/
+  sudo cp build/src/libwhisper.so build/ggml/src/libggml*.so /usr/local/lib/
+  sudo ldconfig
+  ```
+
+#### Download a model
+
+Ask the user which model they want:
+
+| Model | Size | Accuracy | Speed |
+|-------|------|----------|-------|
+| tiny | 75MB | Low | Fastest |
+| base | 147MB | Moderate | Fast |
+| small | 466MB | Good | Moderate |
+| medium | 1.5GB | Very good | Slower |
+| large-v3 | 3.1GB | Best | Slowest |
+
+Default to **base** for a good balance. Download:
+
+```bash
+mkdir -p data/models
+curl -L -o data/models/ggml-{model}.bin "https://huggingface.co/ggerganov/whisper.cpp/resolve/main/ggml-{model}.bin"
+```
+
+Set `WHISPER_MODEL` in `.env` if not using base:
+```
+WHISPER_MODEL=data/models/ggml-{model}.bin
+```
+
+### For API backend
+
+Add to `.env`:
+```
+TRANSCRIPTION_BACKEND=api
+OPENAI_API_KEY=sk-...
+```
+
+## Phase 4: Verify
+
+### Build and restart
+
+```bash
+npm run build
+```
+
+Restart the service:
+```bash
+# macOS
+launchctl kickstart -k gui/$(id -u)/com.nanoclaw
+
+# Linux
+systemctl --user restart nanoclaw
+```
+
+### Test
+
+Send a voice note in any registered group. Channels with transcription support should receive it as `[Voice: <transcript>]`.
+
+### Check logs
+
+```bash
+tail -f logs/nanoclaw.log | grep -i -E "voice|transcri|whisper"
+```
+
+## Configuration
+
+Environment variables (set in `.env`):
+
+| Variable | Default | Description |
+|----------|---------|-------------|
+| `TRANSCRIPTION_BACKEND` | `local` | Backend: `local` or `api` |
+| `WHISPER_BIN` | `whisper-cli` | Path to whisper.cpp binary (local only) |
+| `WHISPER_MODEL` | `data/models/ggml-base.bin` | Path to GGML model file (local only) |
+| `OPENAI_API_KEY` | — | OpenAI API key (api only) |
+
+## Troubleshooting
+
+**"whisper.cpp transcription failed"**: Ensure both `whisper-cli` and `ffmpeg` are in PATH. When running as a service, the PATH may be restricted — add the binary locations to the service unit's PATH.
+
+**"OPENAI_API_KEY not set"**: Set the key in `.env` and ensure `TRANSCRIPTION_BACKEND=api`.
+
+**Wrong language**: whisper.cpp auto-detects language. To force a language, set `WHISPER_LANG` env var and modify `src/transcription.ts` to pass `-l $WHISPER_LANG`.

Subject: [PATCH 3/8] feat: add voice message transcription support

Downloads and transcribes Telegram voice messages using the transcription
skill if installed. Falls back gracefully with a helpful message when
the skill is not present.

+name: add-transcription
+description: Add voice transcription support to NanoClaw. Channel-agnostic — works with any channel that provides audio buffers. Supports local whisper.cpp or OpenAI Whisper API.
+---
+
+# Add Transcription
+
+Adds a channel-agnostic voice transcription module (`src/transcription.ts`). Any channel skill (Telegram, WhatsApp, Discord, etc.) can dynamically import this module to transcribe voice messages.
+
+Two backends are supported:
+- **Local** (default): Uses `whisper-cli` (whisper.cpp) + `ffmpeg`. No API key, no network, no cost.
+- **API**: Uses OpenAI Whisper API. Requires `OPENAI_API_KEY`.
+
+## Phase 1: Pre-flight
+
+### Check if already applied
+
+```bash
+grep 'export async function transcribe' src/transcription.ts && echo "Already applied" || echo "Not applied"
+```
+
+If already applied, skip to Phase 3 (Verify).
+
+### Ask which backend
+
+Ask the user which transcription backend they want:
+
+1. **Local (whisper.cpp)** — free, private, requires ffmpeg + whisper-cli + model download
+2. **OpenAI Whisper API** — easy setup, requires API key, sends audio to OpenAI
+
+Default to local if the user has no preference.
+
+## Phase 2: Apply Code Changes
+
+### Ensure remote
+
+```bash
+git remote -v
+```
+
+If `transcribe` is missing, add it:
+
+```bash
+git remote add transcribe https://github.com/kky/nanoclaw-transcribe.git
+```
+
+### Merge the skill branch
+
+```bash
+git fetch transcribe skill/transcribe
+git merge transcribe/skill/transcribe || {
+  git checkout --theirs package-lock.json
+  git add package-lock.json
+  git merge --continue
+}
+```
+
+### Validate
+
+```bash
+npm run build
+```
+
+## Phase 3: Install Dependencies
+
+### For local backend
+
+#### Install ffmpeg
+
+- **macOS**: `brew install ffmpeg`
+- **Linux**: `sudo apt install ffmpeg`
+
+#### Install whisper.cpp
+
+- **macOS**: `brew install whisper-cpp` (provides `whisper-cli`)
+- **Linux**: Build from source:
+  ```bash
+  cd /tmp && git clone --depth 1 https://github.com/ggerganov/whisper.cpp.git
+  cd whisper.cpp && cmake -B build && cmake --build build -j$(nproc)
+  sudo cp build/bin/whisper-cli /usr/local/bin/
+  sudo cp build/src/libwhisper.so build/ggml/src/libggml*.so /usr/local/lib/
+  sudo ldconfig
+  ```
+
+#### Download a model
+
+Ask the user which model they want:
+
+| Model | Size | Accuracy | Speed |
+|-------|------|----------|-------|
+| tiny | 75MB | Low | Fastest |
+| base | 147MB | Moderate | Fast |
+| small | 466MB | Good | Moderate |
+| medium | 1.5GB | Very good | Slower |
+| large-v3 | 3.1GB | Best | Slowest |
+
+Default to **base** for a good balance. Download:
+
+```bash
+mkdir -p data/models
+curl -L -o data/models/ggml-{model}.bin "https://huggingface.co/ggerganov/whisper.cpp/resolve/main/ggml-{model}.bin"
+```
+
+Set `WHISPER_MODEL` in `.env` if not using base:
+```
+WHISPER_MODEL=data/models/ggml-{model}.bin
+```
+
+### For API backend
+
+Add to `.env`:
+```
+TRANSCRIPTION_BACKEND=api
+OPENAI_API_KEY=sk-...
+```
+
+## Phase 4: Verify
+
+### Build and restart
+
+```bash
+npm run build
+```
+
+Restart the service:
+```bash
+# macOS
+launchctl kickstart -k gui/$(id -u)/com.nanoclaw
+
+# Linux
+systemctl --user restart nanoclaw
+```
+
+### Test
+
+Send a voice note in any registered group. Channels with transcription support should receive it as `[Voice: <transcript>]`.
+
+### Check logs
+
+```bash
+tail -f logs/nanoclaw.log | grep -i -E "voice|transcri|whisper"
+```
+
+## Configuration
+
+Environment variables (set in `.env`):
+
+| Variable | Default | Description |
+|----------|---------|-------------|
+| `TRANSCRIPTION_BACKEND` | `local` | Backend: `local` or `api` |
+| `WHISPER_BIN` | `whisper-cli` | Path to whisper.cpp binary (local only) |
+| `WHISPER_MODEL` | `data/models/ggml-base.bin` | Path to GGML model file (local only) |
+| `OPENAI_API_KEY` | — | OpenAI API key (api only) |
+
+## Troubleshooting
+
+**"whisper.cpp transcription failed"**: Ensure both `whisper-cli` and `ffmpeg` are in PATH. When running as a service, the PATH may be restricted — add the binary locations to the service unit's PATH.
+
+**"OPENAI_API_KEY not set"**: Set the key in `.env` and ensure `TRANSCRIPTION_BACKEND=api`.
+
+**Wrong language**: whisper.cpp auto-detects language. To force a language, set `WHISPER_LANG` env var and modify `src/transcription.ts` to pass `-l $WHISPER_LANG`.

Subject: [PATCH 7/8] fix: restore grammy dependency dropped during
 transcription merge and add type annotations

The transcription skill merge resolved package.json conflicts with --theirs,
which dropped grammy. Updated the add-transcription SKILL.md to warn against
this pattern. Also added explicit `any` type annotations to telegram.ts
callbacks to fix strict-mode TS errors.

+git merge transcribe/skill/transcribe
 ```
 
+If the merge has conflicts, resolve them carefully:
+
+- **package-lock.json**: Safe to use `git checkout --theirs package-lock.json` — `npm install` will regenerate it.
+- **package.json**: Do NOT use `--theirs` — this drops dependencies from other installed skills (e.g. `grammy` from Telegram). Instead, manually resolve: keep all `dependencies` from both sides, accept the incoming version/metadata fields.
+- **Other files** (e.g. `repo-tokens/badge.svg`, `.claude/skills/`): Safe to use `--theirs`.
+
+After resolving, `git add` the resolved files and `git merge --continue`.
+
 ### Validate
 
 ```bash
+npm install
 npm run build
 ```
 
+The `npm install` is important — it regenerates `package-lock.json` from the resolved `package.json` and ensures all dependencies from both sides are installed.
+
 ## Phase 3: Install Dependencies

-name: add-transcription
-description: Add voice transcription support to NanoClaw. Channel-agnostic — works with any channel that provides audio buffers. Supports local whisper.cpp or OpenAI Whisper API.
----
-
-# Add Transcription
-
-Adds a channel-agnostic voice transcription module (`src/transcription.ts`). Any channel skill (Telegram, WhatsApp, Discord, etc.) can dynamically import this module to transcribe voice messages.
-
-Two backends are supported:
-- **Local** (default): Uses `whisper-cli` (whisper.cpp) + `ffmpeg`. No API key, no network, no cost.
-- **API**: Uses OpenAI Whisper API. Requires `OPENAI_API_KEY`.
-
-## Phase 1: Pre-flight
-
-### Check if already applied
-
-```bash
-grep 'export async function transcribe' src/transcription.ts && echo "Already applied" || echo "Not applied"
-```
-
-If already applied, skip to Phase 3 (Verify).
-
-### Ask which backend
-
-Ask the user which transcription backend they want:
-
-1. **Local (whisper.cpp)** — free, private, requires ffmpeg + whisper-cli + model download
-2. **OpenAI Whisper API** — easy setup, requires API key, sends audio to OpenAI
-
-Default to local if the user has no preference.
-
-## Phase 2: Apply Code Changes
-
-### Merge the skill branch
-
-```bash
-git remote add transcribe https://github.com/kky/nanoclaw-transcribe.git
-git fetch transcribe skill/transcribe
-git merge transcribe/skill/transcribe
-```
-
-If the merge has conflicts, resolve them carefully:
-
-- **package-lock.json**: Safe to use `git checkout --theirs package-lock.json` — `npm install` will regenerate it.
-- **package.json**: Do NOT use `--theirs` — this drops dependencies from other installed skills (e.g. `grammy` from Telegram). Instead, manually resolve: keep all `dependencies` from both sides, accept the incoming version/metadata fields.
-- **Other files** (e.g. `repo-tokens/badge.svg`, `.claude/skills/`): Safe to use `--theirs`.
-
-After resolving, `git add` the resolved files and `git merge --continue`.
-
-### Validate
-
-```bash
-npm install
-npm run build
-```
-
-The `npm install` is important — it regenerates `package-lock.json` from the resolved `package.json` and ensures all dependencies from both sides are installed.
-
-## Phase 3: Install Dependencies
-
-### For local backend
-
-#### Install ffmpeg
-
-- **macOS**: `brew install ffmpeg`
-- **Linux**: `sudo apt install ffmpeg`
-
-#### Install whisper.cpp
-
-- **macOS**: `brew install whisper-cpp` (provides `whisper-cli`)
-- **Linux**: Build from source:
-  ```bash
-  cd /tmp && git clone --depth 1 https://github.com/ggerganov/whisper.cpp.git
-  cd whisper.cpp && cmake -B build && cmake --build build -j$(nproc)
-  sudo cp build/bin/whisper-cli /usr/local/bin/
-  sudo cp build/src/libwhisper.so build/ggml/src/libggml*.so /usr/local/lib/
-  sudo ldconfig
-  ```
-
-#### Download a model
-
-Ask the user which model they want:
-
-| Model | Size | Accuracy | Speed |
-|-------|------|----------|-------|
-| tiny | 75MB | Low | Fastest |
-| base | 147MB | Moderate | Fast |
-| small | 466MB | Good | Moderate |
-| medium | 1.5GB | Very good | Slower |
-| large-v3 | 3.1GB | Best | Slowest |
-
-Default to **base** for a good balance. Download:
-
-```bash
-mkdir -p data/models
-curl -L -o data/models/ggml-{model}.bin "https://huggingface.co/ggerganov/whisper.cpp/resolve/main/ggml-{model}.bin"
-```
-
-Set `WHISPER_MODEL` in `.env` if not using base:
-```
-WHISPER_MODEL=data/models/ggml-{model}.bin
-```
-
-### For API backend
-
-Add to `.env`:
-```
-TRANSCRIPTION_BACKEND=api
-OPENAI_API_KEY=sk-...
-```
-
-## Phase 4: Verify
-
-### Build and restart
-
-```bash
-npm run build
-```
-
-Restart the service:
-```bash
-# macOS
-launchctl kickstart -k gui/$(id -u)/com.nanoclaw
-
-# Linux
-systemctl --user restart nanoclaw
-```
-
-### Test
-
-Send a voice note in any registered group. Channels with transcription support should receive it as `[Voice: <transcript>]`.
-
-### Check logs
-
-```bash
-tail -f logs/nanoclaw.log | grep -i -E "voice|transcri|whisper"
-```
-
-## Configuration
-
-Environment variables (set in `.env`):
-
-| Variable | Default | Description |
-|----------|---------|-------------|
-| `TRANSCRIPTION_BACKEND` | `local` | Backend: `local` or `api` |
-| `WHISPER_BIN` | `whisper-cli` | Path to whisper.cpp binary (local only) |
-| `WHISPER_MODEL` | `data/models/ggml-base.bin` | Path to GGML model file (local only) |
-| `OPENAI_API_KEY` | — | OpenAI API key (api only) |
-
-## Troubleshooting
-
-**"whisper.cpp transcription failed"**: Ensure both `whisper-cli` and `ffmpeg` are in PATH. When running as a service, the PATH may be restricted — add the binary locations to the service unit's PATH.
-
-**"OPENAI_API_KEY not set"**: Set the key in `.env` and ensure `TRANSCRIPTION_BACKEND=api`.
-
-**Wrong language**: whisper.cpp auto-detects language. To force a language, set `WHISPER_LANG` env var and modify `src/transcription.ts` to pass `-l $WHISPER_LANG`.
