augment
Augment Kokoro TTS engine — upgrade dependencies and model. Renamed from 'upgrade' to avoid clashing with Claude Code's built-in.
What this skill does
# Augment Kokoro TTS
Upgrade MLX-Audio dependencies, re-download the model, and update bundled scripts.
> **Self-Evolving Skill**: This skill improves through use. If instructions are wrong, parameters drifted, or a workaround was needed — fix this file immediately, don't defer. Only update for real, reproducible issues.
## Workflow
### Step 1: Pre-upgrade health check
```bash
PLUGIN_DIR="${CLAUDE_PLUGIN_ROOT:-$HOME/.claude/plugins/marketplaces/cc-skills/plugins/kokoro-tts}"
bash "$PLUGIN_DIR/scripts/kokoro-install.sh" --health
cat ~/.local/share/kokoro/version.json
```
### Step 2: Execute upgrade
```bash
PLUGIN_DIR="${CLAUDE_PLUGIN_ROOT:-$HOME/.claude/plugins/marketplaces/cc-skills/plugins/kokoro-tts}"
bash "$PLUGIN_DIR/scripts/kokoro-install.sh" --upgrade
```
This upgrades:
- Python packages: `mlx-audio`, `soundfile`, `numpy`
- Model weights: re-downloaded from `mlx-community/Kokoro-82M-bf16`
- Bundled scripts: `kokoro_common.py` and `tts_generate.py` re-copied from plugin
- `version.json`: rewritten with new versions
### Step 3: Post-upgrade verification
```bash
PLUGIN_DIR="${CLAUDE_PLUGIN_ROOT:-$HOME/.claude/plugins/marketplaces/cc-skills/plugins/kokoro-tts}"
bash "$PLUGIN_DIR/scripts/kokoro-install.sh" --health
cat ~/.local/share/kokoro/version.json
# Test synthesis
~/.local/share/kokoro/.venv/bin/python ~/.local/share/kokoro/tts_generate.py \
--text "Upgrade verification" --voice af_heart --lang en-us --speed 1.0 \
--output /tmp/kokoro-upgrade-test.wav && echo "OK"
```
## Rollback
If upgrade breaks TTS, do a clean reinstall:
```bash
PLUGIN_DIR="${CLAUDE_PLUGIN_ROOT:-$HOME/.claude/plugins/marketplaces/cc-skills/plugins/kokoro-tts}"
bash "$PLUGIN_DIR/scripts/kokoro-install.sh" --uninstall
bash "$PLUGIN_DIR/scripts/kokoro-install.sh" --install
```
Model cache is preserved across uninstall, so reinstall reuses the cached model.
## Troubleshooting
| Issue | Cause | Solution |
| ------------------- | ------------------------- | ----------------------------------------------- |
| Upgrade fails | No internet or PyPI down | Check connectivity, retry |
| Import error after | mlx-audio incompatibility | Clean reinstall: `--uninstall` then `--install` |
| Model download slow | Large download | Wait for HuggingFace download to complete |
## Post-Execution Reflection
After this skill completes, reflect before closing the task:
0. **Locate yourself.** — Find this SKILL.md's canonical path before editing.
1. **What failed?** — Fix the instruction that caused it.
2. **What worked better than expected?** — Promote to recommended practice.
3. **What drifted?** — Fix any script, reference, or dependency that no longer matches reality.
4. **Log it.** — Evolution-log entry with trigger, fix, and evidence.
Do NOT defer. The next invocation inherits whatever you leave behind.

watch
IncludedWatch a video (URL or local path). Downloads with yt-dlp, extracts auto-scaled frames with ffmpeg, pulls the transcript from captions (or Whisper API fallback), and hands the result to Claude so it can answer questions about what's in the video.
physical-ai-defect-image-generation
IncludedUse when the user wants to orchestrate defect image generation, run associated setup, or handle outputs on OSMO. The Day 0 path handles cold-start with USD-to-ROI, image-edit augmentation, and AnomalyGen to create initial PCBA datasets. The Day 1 path performs inference and labeling on real images. This skill helps with first-time asset setup, creation of finetuning checkpoints, and configuring deployment. Trigger keywords: defect image generation, dig workflow, dig pipeline, defect image detection workflow, aoi pipeline, aoi anomalygen, usd2roi anomalygen, day 0 pcba, day 1 pcba, day 1 real-photo alignment, day 1 manual roi, metal surface anomaly, glass defect, anomalygen finetune, setup_pcb, setup_metal, setup_glass, setup_pretrained, dig setup, dig datasets, dig pretrained checkpoint, dig image-edit endpoint.
accelint-react-best-practices
IncludedReact performance optimization and best practices. ALWAYS use this skill when working with any React code - writing components, hooks, JSX; refactoring; optimizing re-renders, memoization, state management; reviewing for performance; fixing hydration mismatches; debugging infinite re-renders, stale closures, input focus loss, animations restarting; preventing remounting; implementing transitions, lazy initialization, effect dependencies. Even simple React tasks benefit from these patterns. Covers React 19+ (useEffectEvent, Activity, ref props). Triggers - useEffect, useState, useMemo, useCallback, memo, inline components, nested components, components inside components, re-render, performance, hydration, SSR, Next.js, useDeferredValue, combined hooks.
elevenlabs-agents
IncludedBuild conversational AI voice agents with ElevenLabs Platform using React, JavaScript, React Native, or Swift SDKs. Configure agents, tools (client/server/MCP), RAG knowledge bases, multi-voice, and Scribe real-time STT. Use when: building voice chat interfaces, implementing AI phone agents with Twilio, configuring agent workflows or tools, adding RAG knowledge bases, testing with CLI "agents as code", or troubleshooting deprecated @11labs packages, Android audio cutoff, CSP violations, dynamic variables, or WebRTC config.

humanizer
IncludedHumanize AI-generated text by detecting and removing patterns typical of LLM output. Rewrites text to sound natural, specific, and human. Uses 28 pattern detectors, 560+ AI vocabulary terms across 3 tiers, and statistical analysis (burstiness, type-token ratio, readability) for comprehensive detection. Use when asked to humanize text, de-AI writing, make content sound more natural/human, review writing for AI patterns, score text for AI detection, or improve AI-generated drafts. Covers content, language, style, communication, and filler categories.
generating-mermaid-diagrams
IncludedSalesforce architecture diagrams using Mermaid with ASCII fallback. Use this skill when generating text-based diagrams for Salesforce architecture, OAuth flows, ERDs, integration sequences, or Agentforce structure. TRIGGER when: user says "diagram", "visualize", "ERD", or asks for sequence diagrams, flowcharts, class diagrams, or architecture visualizations in Mermaid. DO NOT TRIGGER when: user wants PNG/SVG image output (use generating-visual-diagrams), or asks about non-Salesforce systems.
