fix(nix): build web dashboard frontend in Nix package

* Add setuptools build dep for legacy alibabacloud packages and updated
stale npm-deps hash

* Add HERMES_NODE env var to pin Node.js version

The TUI requires Node.js 20+ for regex `/v` flag support (used by
string-width). Instead of relying on PATH lookup, explicitly set
HERMES_NODE to the bundled Node 22 in the Nix wrapper, and add a
fallback check in the Python code to use HERMES_NODE if available.

Also upgrade container provisioning to Node 22 via NodeSource (Ubuntu
24.04 ships Node 18 which is EOL) and add a Nix check to verify the
wrapper and Node version at build time.

+## TUI Architecture (ui-tui + tui_gateway)
+
+The TUI is a full replacement for the classic (prompt_toolkit) CLI, activated via `hermes --tui` or `HERMES_TUI=1`.
+
+### Process Model
+
+```
+hermes --tui
+  └─ Node (Ink)  ──stdio JSON-RPC──  Python (tui_gateway)
+       │                                  └─ AIAgent + tools + sessions
+       └─ renders transcript, composer, prompts, activity
+```
+
+TypeScript owns the screen. Python owns sessions, tools, model calls, and slash command logic.
+
+### Transport
+
+Newline-delimited JSON-RPC over stdio. Requests from Ink, events from Python. See `tui_gateway/server.py` for the full method/event catalog.
+
+### Key Surfaces
+
+| Surface | Ink component | Gateway method |
+|---------|---------------|----------------|
+| Chat streaming | `app.tsx` + `messageLine.tsx` | `prompt.submit` → `message.delta/complete` |
+| Tool activity | `thinking.tsx` | `tool.start/progress/complete` |
+| Approvals | `prompts.tsx` | `approval.respond` ← `approval.request` |
+| Clarify/sudo/secret | `prompts.tsx`, `maskedPrompt.tsx` | `clarify/sudo/secret.respond` |
+| Session picker | `sessionPicker.tsx` | `session.list/resume` |
+| Slash commands | Local handler + fallthrough | `slash.exec` → `_SlashWorker`, `command.dispatch` |
+| Completions | `useCompletion` hook | `complete.slash`, `complete.path` |
+| Theming | `theme.ts` + `branding.tsx` | `gateway.ready` with skin data |
+
+### Slash Command Flow
+
+1. Built-in client commands (`/help`, `/quit`, `/clear`, `/resume`, `/copy`, `/paste`, etc.) handled locally in `app.tsx`
+2. Everything else → `slash.exec` (runs in persistent `_SlashWorker` subprocess) → `command.dispatch` fallback
+
+### Dev Commands
+
+```bash
+cd ui-tui
+npm install       # first time
+npm run dev       # watch mode (rebuilds hermes-ink + tsx --watch)
+npm start         # production
+npm run build     # full build (hermes-ink + tsc)
+npm run type-check # typecheck only (tsc --noEmit)
+npm run lint      # eslint
+npm run fmt       # prettier
+npm test          # vitest

 ## Testing
 
+**ALWAYS use `scripts/run_tests.sh`** — do not call `pytest` directly. The script enforces
+hermetic environment parity with CI (unset credential vars, TZ=UTC, LANG=C.UTF-8,
+4 xdist workers matching GHA ubuntu-latest). Direct `pytest` on a 16+ core
+developer machine with API keys set diverges from CI in ways that have caused
+multiple "works locally, fails in CI" incidents (and the reverse).

 ```
 
+### Why the wrapper (and why the old "just call pytest" doesn't work)
+
+Five real sources of local-vs-CI drift the script closes:
+
+| | Without wrapper | With wrapper |
+|---|---|---|
+| Provider API keys | Whatever is in your env (auto-detects pool) | All `*_API_KEY`/`*_TOKEN`/etc. unset |
+| HOME / `~/.hermes/` | Your real config+auth.json | Temp dir per test |
+| Timezone | Local TZ (PDT etc.) | UTC |
+| Locale | Whatever is set | C.UTF-8 |
+| xdist workers | `-n auto` = all cores (20+ on a workstation) | `-n 4` matching CI |
+
+`tests/conftest.py` also enforces points 1-4 as an autouse fixture so ANY pytest
+invocation (including IDE integrations) gets hermetic behavior — but the wrapper
+is belt-and-suspenders.
+
+### Running without the wrapper (only if you must)
+
+If you can't use the wrapper (e.g. on Windows or inside an IDE that shells
+pytest directly), at minimum activate the venv and pass `-n 4`:
+
+```bash
+source venv/bin/activate
+python -m pytest tests/ -q -n 4
+```
+
+Worker count above 4 will surface test-ordering flakes that CI never sees.
+
 Always run the full suite before pushing changes.

+`server.py` owns the full runtime-control surface: session store (`_sessions: dict[str, dict]`), method registry (`@method("…")` decorator), event emitter (`_emit`), agent lifecycle (`_make_agent`, `_init_session`, `_wire_callbacks`), approval/sudo/clarify round-trips, and JSON-RPC dispatch.
+
+Protocol methods (`@method(...)` in `server.py`):
+
+- session: `session.{create, resume, list, close, interrupt, usage, history, compress, branch, title, save, undo}`
+- prompt: `prompt.{submit, background, btw}`
+- tools: `tools.{list, show, configure}`
+- slash: `slash.exec`, `command.{dispatch, resolve}`, `commands.catalog`, `complete.{path, slash}`
+- approvals: `approval.respond`, `sudo.respond`, `clarify.respond`, `secret.respond`
+- config/state: `config.{get, set, show}`, `model.options`, `reload.mcp`
+- ops: `shell.exec`, `cli.exec`, `terminal.resize`, `input.detect_drop`, `clipboard.paste`, `paste.collapse`, `image.attach`, `process.stop`
+- misc: `agents.list`, `skills.manage`, `plugins.list`, `cron.manage`, `insights.get`, `rollback.{list, diff, restore}`, `browser.manage`
+
+Protocol events (`_emit(…)` → handled in `ui-tui/src/app/createGatewayEventHandler.ts`):
+
+- lifecycle: `gateway.{ready, stderr}`, `session.info`, `skin.changed`
+- stream: `message.{start, delta, complete}`, `thinking.delta`, `reasoning.{delta, available}`, `status.update`
+- tools: `tool.{start, progress, complete, generating}`, `subagent.{start, thinking, tool, progress, complete}`
+- interactive: `approval.request`, `sudo.request`, `clarify.request`, `secret.request`

+### CLI entry points — `hermes_cli/main.py`
+
+- `hermes --tui`      → `node dist/entry.js` (auto-builds when `.ts`/`.tsx` newer than `dist/entry.js`)
+- `hermes --tui --dev` → `tsx src/entry.tsx` (skip build)
+- `HERMES_TUI_DIR=…`  → external prebuilt dist (nix, distro packaging)
+
+## Diverged From Original Plan
+
+| Plan | Reality | Why |
+|---|---|---|
+| `tui_gateway/{controller,session_state,events,protocol}.py` | all collapsed into `server.py` | no second consumer ever emerged, keeping one file cheaper than four |
+| `ui-tui/src/main.tsx` | split into `entry.tsx` (bootstrap) + `app.tsx` (shell) | boot banner + early python spawn wanted a pre-React moment |
+| `ui-tui/src/state/store.ts` | three nanostores (`uiStore`, `turnStore`, `overlayStore`) | separate lifetimes: ui persists, turn resets per reply, overlay is modal |
+| `approval.requested` / `sudo.requested` / `clarify.requested` | `*.request` (no `-ed`) | cosmetic |
+| `session.cancel` | dropped | `session.interrupt` covers it |
+| `HERMES_EXPERIMENTAL_TUI=1`, `display.experimental_tui: true`, `/tui on/off/status` | none shipped | `--tui` went from opt-in to first-class without an experimental phase |
+
+## Post-migration Additions (not in original plan)
+
+- **Async `session.create`** — returns sid in ~1ms, agent builds on a background thread, `session.info` broadcasts when ready; `_wait_agent()` gates every agent-touching handler via `_sess`
+- **`bootBanner`** — raw-ANSI logo painted to stdout at T≈2ms, before Ink loads; `<AlternateScreen>` wipes it seamlessly when React mounts
+- **Selection uniform bg** — `theme.color.selectionBg` wired via `useSelection().setSelectionBgColor`; replaces SGR-inverse per-cell swap that fragmented over amber/gold fg
+- **Slash command registry** — TS-owned commands in `app/slash/commands/{core,ops,session}.ts`, everything else falls through to `slash.exec` (python worker)
+- **Turn store + controller split** — imperative singleton (`turnController`) holds refs/timers, nanostore (`turnStore`) holds render-visible state
+
+## What's Still Open
+
+- **Classic CLI not deleted.** `cli.py` still has ~80 `prompt_toolkit` references; classic REPL is still the default when `--tui` is absent. The original plan's "Cut 4 · prompt_toolkit removal later" hasn't happened.
+- **No config-file opt-in.** `HERMES_EXPERIMENTAL_TUI` and `display.experimental_tui` were never built; only the CLI flag exists. Fine for now — if we want "default to TUI", a single line in `main.py` flips it.

+      ``_seed_from_singletons()`` during pool load.
+    - ``credential_pool.nous``: used by the runtime ``pool.select()`` path.
+

+    entry from the singleton.  Re-running login upserts the same entry in
+    place; the pool never accumulates duplicate device_code rows.
+
+    ``label`` is an optional user-chosen display name (from
+    ``hermes auth add nous --label <name>``).  It gets embedded in the
+    singleton state so that ``_seed_from_singletons`` uses it as the pool
+    entry's label on every subsequent ``load_pool("nous")`` instead of the
+    auto-derived token fingerprint.  When ``None``, the auto-derived label
+    via ``label_from_token`` is used (unchanged default behaviour).

-# GGUF - Quantization Format for llama.cpp
-
-The GGUF (GPT-Generated Unified Format) is the standard file format for llama.cpp, enabling efficient inference on CPUs, Apple Silicon, and GPUs with flexible quantization options.
-
-## When to use GGUF
-
-**Use GGUF when:**
-- Deploying on consumer hardware (laptops, desktops)
-- Running on Apple Silicon (M1/M2/M3) with Metal acceleration
-- Need CPU inference without GPU requirements
-- Want flexible quantization (Q2_K to Q8_0)
-- Using local AI tools (LM Studio, Ollama, text-generation-webui)
-
-**Key advantages:**
-- **Universal hardware**: CPU, Apple Silicon, NVIDIA, AMD support
-- **No Python runtime**: Pure C/C++ inference
-- **Flexible quantization**: 2-8 bit with various methods (K-quants)
-- **Ecosystem support**: LM Studio, Ollama, koboldcpp, and more
-- **imatrix**: Importance matrix for better low-bit quality
-
-**Use alternatives instead:**
-- **AWQ/GPTQ**: Maximum accuracy with calibration on NVIDIA GPUs
-- **HQQ**: Fast calibration-free quantization for HuggingFace
-- **bitsandbytes**: Simple integration with transformers library
-- **TensorRT-LLM**: Production NVIDIA deployment with maximum speed
-

-```
-
-### Run inference
-
-```bash
-# CLI inference
-./llama-cli -m model-q4_k_m.gguf -p "Hello, how are you?"
-
-# Interactive mode
-./llama-cli -m model-q4_k_m.gguf --interactive
-
-# With GPU offload
-./llama-cli -m model-q4_k_m.gguf -ngl 35 -p "Hello!"
-```
-
-## Quantization types
-
-### K-quant methods (recommended)
-
-| Type | Bits | Size (7B) | Quality | Use Case |
-|------|------|-----------|---------|----------|
-| Q2_K | 2.5 | ~2.8 GB | Low | Extreme compression |
-| Q3_K_S | 3.0 | ~3.0 GB | Low-Med | Memory constrained |
-| Q3_K_M | 3.3 | ~3.3 GB | Medium | Balance |
-| Q4_K_S | 4.0 | ~3.8 GB | Med-High | Good balance |
-| Q4_K_M | 4.5 | ~4.1 GB | High | **Recommended default** |
-| Q5_K_S | 5.0 | ~4.6 GB | High | Quality focused |
-| Q5_K_M | 5.5 | ~4.8 GB | Very High | High quality |
-| Q6_K | 6.0 | ~5.5 GB | Excellent | Near-original |
-| Q8_0 | 8.0 | ~7.2 GB | Best | Maximum quality |
-
-### Legacy methods
-
-| Type | Description |
-|------|-------------|
-| Q4_0 | 4-bit, basic |
-| Q4_1 | 4-bit with delta |
-| Q5_0 | 5-bit, basic |
-| Q5_1 | 5-bit with delta |
-
-**Recommendation**: Use K-quant methods (Q4_K_M, Q5_K_M) for best quality/size ratio.
-
-## Conversion workflows
-
-### Workflow 1: HuggingFace to GGUF
-
-```bash
-# 1. Download model
-huggingface-cli download meta-llama/Llama-3.1-8B --local-dir ./llama-3.1-8b
-
-# 2. Convert to GGUF (FP16)
-python convert_hf_to_gguf.py ./llama-3.1-8b \
-    --outfile llama-3.1-8b-f16.gguf \
-    --outtype f16
-
-# 3. Quantize
-./llama-quantize llama-3.1-8b-f16.gguf llama-3.1-8b-q4_k_m.gguf Q4_K_M
-
-# 4. Test
-./llama-cli -m llama-3.1-8b-q4_k_m.gguf -p "Hello!" -n 50
-```
-
-### Workflow 2: With importance matrix (better quality)
-
-```bash
-# 1. Convert to GGUF
-python convert_hf_to_gguf.py ./model --outfile model-f16.gguf
-
-# 2. Create calibration text (diverse samples)
-cat > calibration.txt << 'EOF'
-The quick brown fox jumps over the lazy dog.
-Machine learning is a subset of artificial intelligence.
-Python is a popular programming language.
-# Add more diverse text samples...
-EOF
-
-# 3. Generate importance matrix
-./llama-imatrix -m model-f16.gguf \
-    -f calibration.txt \

-    -o model.imatrix \
-    -ngl 35  # GPU layers if available
-
-# 4. Quantize with imatrix
-./llama-quantize --imatrix model.imatrix \
-    model-f16.gguf \
-    model-q4_k_m.gguf \
-    Q4_K_M
-```
-
-### Workflow 3: Multiple quantizations
-
-```bash
-#!/bin/bash
-MODEL="llama-3.1-8b-f16.gguf"
-IMATRIX="llama-3.1-8b.imatrix"
-
-# Generate imatrix once
-./llama-imatrix -m $MODEL -f wiki.txt -o $IMATRIX -ngl 35
-
-# Create multiple quantizations
-for QUANT in Q4_K_M Q5_K_M Q6_K Q8_0; do
-    OUTPUT="llama-3.1-8b-${QUANT,,}.gguf"
-    ./llama-quantize --imatrix $IMATRIX $MODEL $OUTPUT $QUANT
-    echo "Created: $OUTPUT ($(du -h $OUTPUT | cut -f1))"
-done
-```

-```
-
-## Hardware optimization
-
-### Apple Silicon (Metal)
-
-```bash
-# Build with Metal
-make clean && make GGML_METAL=1
-
-# Run with Metal acceleration
-./llama-cli -m model.gguf -ngl 99 -p "Hello"
-
-# Python with Metal
-llm = Llama(
-    model_path="model.gguf",
-    n_gpu_layers=99,     # Offload all layers
-    n_threads=1          # Metal handles parallelism
-)
-```
-
-### NVIDIA CUDA
-
-```bash
-# Build with CUDA
-make clean && make GGML_CUDA=1
-
-# Run with CUDA
-./llama-cli -m model.gguf -ngl 35 -p "Hello"
-
-# Specify GPU
-CUDA_VISIBLE_DEVICES=0 ./llama-cli -m model.gguf -ngl 35
-```
-
-### CPU optimization
-
-```bash
-# Build with AVX2/AVX512
-make clean && make
-
-# Run with optimal threads
-./llama-cli -m model.gguf -t 8 -p "Hello"
-
-# Python CPU config
-llm = Llama(
-    model_path="model.gguf",
-    n_gpu_layers=0,      # CPU only
-    n_threads=8,         # Match physical cores
-    n_batch=512          # Batch size for prompt processing
-)
-```
-
-## Integration with tools
-
-### Ollama
-
-```bash
-# Create Modelfile
-cat > Modelfile << 'EOF'
-FROM ./model-q4_k_m.gguf
-TEMPLATE """{{ .System }}
-{{ .Prompt }}"""
-PARAMETER temperature 0.7
-PARAMETER num_ctx 4096
-EOF
-
-# Create Ollama model
-ollama create mymodel -f Modelfile
-
-# Run
-ollama run mymodel "Hello!"
-```
-
-### LM Studio
-
-1. Place GGUF file in `~/.cache/lm-studio/models/`
-2. Open LM Studio and select the model
-3. Configure context length and GPU offload
-4. Start inference
-
-### text-generation-webui
-
-```bash
-# Place in models folder
-cp model-q4_k_m.gguf text-generation-webui/models/
-
-# Start with llama.cpp loader
-python server.py --model model-q4_k_m.gguf --loader llama.cpp --n-gpu-layers 35
-```
-
-## Best practices
-
-1. **Use K-quants**: Q4_K_M offers best quality/size balance
-2. **Use imatrix**: Always use importance matrix for Q4 and below
-3. **GPU offload**: Offload as many layers as VRAM allows
-4. **Context length**: Start with 4096, increase if needed
-5. **Thread count**: Match physical CPU cores, not logical
-6. **Batch size**: Increase n_batch for faster prompt processing
-
-## Common issues
-
-**Model loads slowly:**
-```bash
-# Use mmap for faster loading
-./llama-cli -m model.gguf --mmap
-```
-
-**Out of memory:**
-```bash
-# Reduce GPU layers
-./llama-cli -m model.gguf -ngl 20  # Reduce from 35
-
-# Or use smaller quantization
-./llama-quantize model-f16.gguf model-q3_k_m.gguf Q3_K_M
-```
-
-**Poor quality at low bits:**
-```bash
-# Always use imatrix for Q4 and below
-./llama-imatrix -m model-f16.gguf -f calibration.txt -o model.imatrix
-./llama-quantize --imatrix model.imatrix model-f16.gguf model-q4_k_m.gguf Q4_K_M
-```

-| Format | Bits | Size (7B) | Speed | Quality | Use Case |
-|--------|------|-----------|-------|---------|----------|
-| **Q4_K_M** | 4.5 | 4.1 GB | Fast | Good | **Recommended default** |
-| Q4_K_S | 4.3 | 3.9 GB | Faster | Lower | Speed critical |
-| Q5_K_M | 5.5 | 4.8 GB | Medium | Better | Quality critical |
-| Q6_K | 6.5 | 5.5 GB | Slower | Best | Maximum quality |
-| Q8_0 | 8.0 | 7.0 GB | Slow | Excellent | Minimal degradation |
-| Q2_K | 2.5 | 2.7 GB | Fastest | Poor | Testing only |
+| Type | Bits | Size (7B) | Quality | Use Case |
+|------|------|-----------|---------|----------|
+| Q2_K | 2.5 | ~2.8 GB | Low | Extreme compression (testing only) |
+| Q3_K_S | 3.0 | ~3.0 GB | Low-Med | Memory constrained |
+| Q3_K_M | 3.3 | ~3.3 GB | Medium | Fits small devices |
+| Q4_K_S | 4.0 | ~3.8 GB | Med-High | Speed critical |

+| Q6_K | 6.0 | ~5.5 GB | Excellent | Near-original |
+| Q8_0 | 8.0 | ~7.2 GB | Best | Maximum quality, minimal degradation |
 
-### Choosing quantization
+**Variant suffixes** — `_S` (Small, faster, lower quality), `_M` (Medium, balanced), `_L` (Large, better quality).
+
+**Legacy (Q4_0/Q4_1/Q5_0/Q5_1) exist** but always prefer K-quants for better quality/size ratio.
+
+**IQ quantization** — ultra-low-bit with importance-aware methods: IQ2_XXS, IQ2_XS, IQ2_S, IQ3_XXS, IQ3_XS, IQ3_S, IQ4_XS. Require `--imatrix`.
+
+**Task-specific defaults:**
+- General chat / assistants: Q4_K_M, or Q5_K_M if RAM allows
+- Code generation: Q5_K_M or Q6_K (higher precision helps)
+- Technical / medical: Q6_K or Q8_0
+- Very large (70B, 405B) on consumer hardware: Q3_K_M or Q4_K_S
+- Raspberry Pi / edge: Q2_K or Q3_K_S
+
+## Conversion workflows
+
+### Basic: HF → GGUF → quantized
 
 ```bash
-# General use (balanced)
-Q4_K_M  # 4-bit, medium quality
+python convert_hf_to_gguf.py ./model --outfile model-f16.gguf --outtype f16
+./llama-quantize model-f16.gguf model-q4_k_m.gguf Q4_K_M
+./llama-cli -m model-q4_k_m.gguf -p "Hello!" -n 50
+```
 
-# Maximum speed (more degradation)
-Q2_K or Q3_K_M
+### With importance matrix (imatrix) — better low-bit quality
 
-# Maximum quality (slower)
-Q6_K or Q8_0
+`imatrix` gives 10–20% perplexity improvement at Q4, essential at Q3 and below.
 
-# Very large models (70B, 405B)
-Q3_K_M or Q4_K_S  # Lower bits to fit in memory
+```bash
+# 1. Convert to FP16 GGUF
+python convert_hf_to_gguf.py ./model --outfile model-f16.gguf
+
+# 2. Prepare calibration data (diverse text, ~100MB is ideal)
+cat > calibration.txt << 'EOF'
+The quick brown fox jumps over the lazy dog.
+Machine learning is a subset of artificial intelligence.
+# Add more diverse text samples...
+EOF
+
+# 3. Generate importance matrix
+./llama-imatrix -m model-f16.gguf \
+    -f calibration.txt \
+    --chunk 512 \
+    -o model.imatrix \
+    -ngl 35
+
+# 4. Quantize with imatrix
+./llama-quantize --imatrix model.imatrix \
+    model-f16.gguf model-q4_k_m.gguf Q4_K_M
+```
+
+### Multi-quant batch

+    ./llama-quantize --imatrix $IMATRIX $MODEL $OUTPUT $QUANT
+    echo "Created: $OUTPUT ($(du -h $OUTPUT | cut -f1))"
+done

+
+### Quality testing (perplexity)
+
+```bash
+./llama-perplexity -m model.gguf -f wikitext-2-raw/wiki.test.raw -c 512

+from openai import OpenAI
+
+client = OpenAI(base_url="http://localhost:8080/v1", api_key="not-needed")
+response = client.chat.completions.create(
+    model="local-model",
+    messages=[{"role": "user", "content": "Hello!"}],
+    max_tokens=256,
+)
+print(response.choices[0].message.content)
+```
+
+## Best practices
+
+1. **Use K-quants** — Q4_K_M is the recommended default
+2. **Use imatrix** for Q4 and below (calibration improves quality substantially)
+3. **Offload as many layers as VRAM allows** — start high, reduce by 5 on OOM
+4. **Thread count** — match physical cores, not logical
+5. **Batch size** — increase `n_batch` (e.g. 512) for faster prompt processing
+6. **Context** — start at 4096, grow only as needed (memory scales with ctx)
+7. **Flash Attention** — add `--flash-attn` if your build supports it
+
+## Common issues (quick fixes)
+
+**Model loads slowly** — use `--mmap` for memory-mapped loading.
+
+**Out of memory (GPU)** — reduce `-ngl`, use a smaller quant (Q4_K_S / Q3_K_M), or quantize the KV cache:
+```python
+Llama(model_path="...", type_k=2, type_v=2, n_gpu_layers=35)  # Q4_0 KV cache
+```
+
+**Garbage output** — wrong `chat_format`, temperature too high, or model file corrupted. Test with `temperature=0.1` and verify FP16 baseline works.
+
+**Connection refused (server)** — bind to `--host 0.0.0.0`, check `lsof -i :8080`.
+
+See `references/troubleshooting.md` for the full playbook.

-
-## 🚀 Quick Start
-
-1. **Read SKILL.md** - Comprehensive guide with all concepts and patterns
-2. **Copy `templates/basic_grpo_training.py`** - Start with working code
-3. **Browse `examples/reward_functions_library.py`** - Pick reward functions for your task
-4. **Modify for your use case** - Adapt dataset, rewards, and config
-
-## 💡 What's Inside
-
-### SKILL.md (Main Documentation)
-- Core GRPO concepts and algorithm fundamentals
-- Complete implementation workflow (dataset → rewards → training → deployment)
-- 10+ reward function examples with code
-- Hyperparameter tuning guide
-- Training insights (loss behavior, metrics, debugging)
-- Troubleshooting guide
-- Production best practices
-
-### Templates
-- **basic_grpo_training.py**: Minimal, production-ready training script
-  - Uses Qwen 2.5 1.5B Instruct
-  - 3 reward functions (format + correctness)
-  - LoRA for efficient training
-  - Fully documented and ready to run
-
-### Examples
-- **reward_functions_library.py**: 20+ battle-tested reward functions
-  - Correctness rewards (exact match, fuzzy match, numeric, code execution)
-  - Format rewards (XML, JSON, strict/soft)
-  - Length rewards (ideal length, min/max)
-  - Style rewards (reasoning quality, citations, repetition penalty)
-  - Combined rewards (multi-objective optimization)
-  - Preset collections for common tasks
-
-## 📖 Usage for Agents
-
-When this skill is loaded in your agent's context:
-
-1. **Always read SKILL.md first** before implementing
-2. **Start simple** - Use length-based reward to validate setup
-3. **Build incrementally** - Add one reward function at a time
-4. **Reference examples** - Copy patterns from reward_functions_library.py
-5. **Monitor training** - Watch reward metrics (not loss!)
-
-## 🎯 Common Use Cases
-
-| Task Type | Recommended Rewards | Template |
-|-----------|---------------------|----------|
-| Math reasoning | `MATH_REASONING_REWARDS` preset | basic_grpo_training.py |
-| Code generation | `CODE_GENERATION_REWARDS` preset | Modify dataset in template |
-| Summarization | `SUMMARIZATION_REWARDS` preset | Adjust prompts + rewards |
-| Q&A | `QA_REWARDS` preset | Use fuzzy match + citations |
-
-## ⚠️ Critical Reminders
-
-- **Loss goes UP during training** - This is normal (it's KL divergence)
-- **Use 3-5 reward functions** - Single rewards often fail
-- **Test rewards before training** - Debug each function independently
-- **Monitor reward_std** - Should stay > 0.1 (avoid mode collapse)
-- **Start with num_generations=4-8** - Scale up if GPU allows

-## Usage Instructions for Agents
-
-When this skill is loaded:
-
-1. **Read this entire file** before implementing GRPO training
-2. **Start with the simplest reward function** (e.g., length-based) to validate setup
-3. **Use the templates** in `templates/` directory as starting points
-4. **Reference examples** in `examples/` for task-specific implementations
-5. **Follow the workflow** sequentially (don't skip steps)
-6. **Debug incrementally** - add one reward function at a time
-
-**Critical Reminders:**
-- Always use multiple reward functions (3-5 is optimal)
-- Monitor reward metrics, not loss
-- Test reward functions before training
-- Start small (num_generations=4), scale up gradually
-- Save checkpoints frequently (every 100 steps)
-
-This skill is designed for **expert-level implementation**. Beginners should start with supervised fine-tuning before attempting GRPO.

+## Critical reminders
 
+- **Loss goes UP during training** — this is normal (it's KL divergence)
+- **Use 3–5 reward functions** — single rewards often fail
+- **Test rewards before training** — debug each function independently
+- **Monitor `reward_std`** — should stay > 0.1 (avoid mode collapse)
+- **Start with `num_generations=4–8`** — scale up if GPU allows
