+description: >
+  Generate audio assets for The Settled Reach using the Stable Audio Open API
+  (self-hosted Gradio app at tower-of-joy:11500). Use when generating any game
+  audio: ambient loops, SFX, UI sounds, monologue chimes, footsteps, or any
+  sound asset from docs/assets/audio/. Also use when the user asks about audio
+  generation, sound design pipeline, or audio asset iteration. Triggers on:
+  "generate audio", "make sounds", "create ambient", "audio pipeline",
+  "generate sfx", "stable audio", "gen audio", "sound design".
+---
+
+# Audio Generation — The Settled Reach
+
+Generate sonically consistent audio assets using the Stable Audio Open API via
+wrapper scripts at `db/connectors/audio-*`.
+
+Asset descriptions, filenames, bus routing, and design intent are documented in
+`docs/assets/audio/`. This skill provides the prompt system, generation
+workflow, and quality validation.
+
+## API Access
+
+**Never call the API directly.** Use the wrapper scripts:
+
+```bash
+# Check API health
+db/connectors/audio-health
+
+# Generate a single asset (WAV only)
+db/connectors/audio-generate "prompt text" \
+  --duration 10 --steps 100 --cfg 7 \
+  --output path/to/output.wav
+
+# Generate + post-process in one command (WAV → trim → normalize → OGG)
+db/connectors/audio-generate "prompt text" \
+  --duration 10 --steps 100 --cfg 7 \
+  --output path/to/gen/intermediate.wav \
+  --output-ogg client/assets/audio/final.ogg
+
+# Batch-generate from a manifest (preferred for multiple assets)
+db/connectors/audio-batch docs/assets/audio/batch-s10-327.json
+```
+
+### Parameters
+
+| Parameter | Default | Range | Notes |
+|-----------|---------|-------|-------|
+| `--duration` | 10 | 0-47s | Max 47s per generation. For longer loops, generate 45s with crossfade overlap. |
+| `--steps` | 100 | 10-200 | More steps = better quality, slower. Use 50 for quick previews, 100-150 for final. |
+| `--cfg` | 7 | 1-15 | Classifier-free guidance. Higher = more prompt-adherent but less natural. 5-9 is the sweet spot. |
+| `--output` | auto | — | Output WAV file path. Auto-names from prompt if omitted. |
+| `--post` | off | — | Run trim + normalize + convert after generation. |
+| `--output-ogg` | auto | — | OGG output path (implies `--post`). Defaults to same basename as WAV. |
+| `--timeout` | 600 | — | Max wait in seconds. Generation can take 2-5 minutes on 11GB VRAM. |
+
+### Critical Constraints
+
+- **NEVER parallelize requests.** The server has 11GB VRAM and runs one
+  generation at a time. Always wait for a generation to complete before
+  starting the next. Sequential only.
+- **Generation takes 2-5 minutes** per clip depending on duration and steps.
+  Be patient. The timeout default (600s) is generous.
+- **Max 47 seconds** per generation. For 60-90s ambient loops, generate 45s
+  clips and crossfade-stitch in post-processing.
+
+## Prompt Assembly
+
+Every generation uses three parts:
+
+```
+[SONIC FAMILY PREFIX] + [CATEGORY TEMPLATE] + [ASSET DESCRIPTION from docs/assets/audio/]
+```
+
+Never call the API with just the asset description. Always prepend the sonic
+family prefix and matching category template.
+
+- **Sonic palette and families:** Read `references/sonic-palette.md`
+- **Category templates:** Read `references/category-templates.md` and match by
+  asset type (ambient, sfx, ui)
+- **Asset description:** Look up the specific asset in `docs/assets/audio/{category}.md`
+
+## Batch Workflow (Preferred)
+
+For generating multiple assets, use a manifest file. This reduces prompt
+approvals to 2: one Write (manifest) + one Bash (batch run).
+
+### 1. Create the manifest
+
+Write a JSON manifest to `docs/assets/audio/batch-{sprint}-{ticket}.json`:
+
+```json
+{
+  "description": "Sprint 10 ambient + world SFX batch",
+  "output_dir": "client/assets/audio",
+  "gen_dir": "client/assets/audio/gen",
+  "defaults": {
+    "steps": 100,
+    "cfg": 7,
+    "lufs": -16,
+    "quality": 6
+  },
+  "assets": [
+    {
+      "id": "AMB-001",
+      "filename": "amb_station_base.ogg",
+      "method": "sao",
+      "duration": 45,
+      "steps": 150,
+      "cfg": 5,
+      "prompt": "[sonic family prefix] + [template] + [description]"
+    },
+    {
+      "id": "UI-005",
+      "filename": "sfx_monologue_chime.ogg",
+      "method": "synth",
+      "synth": {
+        "type": "harmonic",
+        "duration": 0.8,
+        "fundamental": 1200,
+        "harmonics": [
+          {"freq": 2400, "db": -12},
+          {"freq": 3600, "db": -24}
+        ],
+        "attack_ms": 15,
+        "sustain_ratio": 0.2,
+        "decay": "exponential"
+      }
+    }
+  ]
+}
+```
+
+Asset `id` values must match IDs in `docs/assets/audio/{category}.md` (e.g.,
+AMB-001, SFX-002, UI-005). This couples the manifest to the asset inventory.
+
+### 2. Run the batch
+
+```bash
+# Full run
+db/connectors/audio-batch docs/assets/audio/batch-s10-327.json
+
+# Dry run — preview what would be generated
+db/connectors/audio-batch docs/assets/audio/batch-s10-327.json --dry-run
+
+# Generate only specific assets
+db/connectors/audio-batch docs/assets/audio/batch-s10-327.json --only AMB-001,AMB-002
+
+# Skip assets that already have OGG files
+db/connectors/audio-batch docs/assets/audio/batch-s10-327.json --skip-existing
+```
+
+### 3. Update asset docs with prompts
+
+After the batch completes, write the exact prompts used back into the
+Prompt/Notes column of `docs/assets/audio/{category}.md`. The manifest records
+what was generated; the asset docs record what we have.
+
+### Manifest fields
+
+| Field | Required | Notes |
+|-------|----------|-------|
+| `id` | yes | Asset ID from docs (AMB-001, SFX-002, UI-005) |
+| `filename` | yes | Output filename (must match asset doc) |
+| `method` | yes | `sao` (Stable Audio Open) or `synth` (harmonic synthesis) |
+| `duration` | SAO only | Duration in seconds |
+| `prompt` | SAO only | Full assembled prompt |
+| `steps` | no | Override default steps |
+| `cfg` | no | Override default CFG |
+| `synth` | synth only | Synthesis parameters (see below) |
+
+### Synth parameters
+
+| Field | Default | Notes |
+|-------|---------|-------|
+| `type` | harmonic | Only `harmonic` supported currently |
+| `duration` | — | Duration in seconds |
+| `fundamental` | — | Fundamental frequency in Hz |
+| `harmonics` | [] | List of `{"freq": Hz, "db": dB}` objects |
+| `attack_ms` | 10 | Attack time in milliseconds |
+| `sustain_ratio` | 0.2 | Fraction of duration at full level before decay |
+| `decay` | exponential | `exponential` or `linear` |
+
+## Single Asset Workflow
+
+For one-off generation or iteration on a specific asset:
+
+1. Find the asset in `docs/assets/audio/{ambient,sfx,ui}.md` — note filename,
+   duration, bus, method, and design intent.
+2. Read `references/sonic-palette.md` for the sonic family prefix.
+3. Read `references/category-templates.md` for the matching template.
+4. Assemble the full prompt.
+5. Run `db/connectors/audio-health` to verify the API is up.
+6. Run `db/connectors/audio-generate` with `--post` or `--output-ogg` to
+   generate and post-process in one step.
+7. Verify the output (file size, duration).
+8. Update the asset status and prompt in `docs/assets/audio/{category}.md`.
+
+## Iteration Workflow
+
+For each asset, generate 4-6 candidates:
+
+1. **Generate candidates** — vary the prompt slightly (add/remove descriptors,
+   adjust CFG between 5-9). Run each generation sequentially — never in
+   parallel.
+2. **Solo test** — does each candidate sound right alone?
+3. **Stack test** — play the candidate alongside other layers. Does it mask or
+   clash?
+4. **Fatigue test** (loops only) — can you listen for 5+ minutes without a
+   jarring repeat?
+5. **Close-your-eyes test** — does it create a mental image or sensation?
+6. Select the best candidate (post-processing is already done if `--post` was
+   used).
+
+## Post-Processing (Standalone)
+
+If you need to post-process separately (e.g., re-normalizing an existing file):
+
+```bash
+# Full pipeline: trim → normalize → convert
+db/connectors/audio-post pipeline input.wav --output output.ogg
+
+# Individual steps
+db/connectors/audio-post trim input.wav
+db/connectors/audio-post normalize input.wav --lufs -16
+db/connectors/audio-post convert input.wav --output output.ogg
+```
+
+## Manual Synthesis (Insert-Tech Sounds)
+
+For sounds under 200ms (cursor hover, weapon aim), Stable Audio Open cannot
+produce meaningful output. Use manual synthesis via `tooling/synth_ui_sounds.py`
+or the batch manifest's `method: "synth"` with harmonic parameters.
+
+For complex synthesis beyond the `harmonic` type (FM, filtered noise, bandpass
+impulse), write a custom script in `tooling/` following the pattern in
+`tooling/synth_ui_sounds.py`.
+
+## Quality Checklist
+
+After generating, verify:
+- Sound matches the sonic family (insert-tech = synthetic/precise, organic = warm/natural)
+- Frequency range doesn't mask other layers (check docs/assets/audio/)
+- Duration matches spec
+- No unwanted artifacts (clicks, pops, digital noise at start/end)
+- Loop point is clean (ambient loops only)
+- Volume sits well relative to other assets (LUFS normalized)
+- Passes the close-your-eyes test
+
+## File Placement
+
+Generated assets go to `client/assets/audio/` with exact filenames from the
+asset docs. Intermediates go to `client/assets/audio/gen/` (gitignored).
+
+AudioManager discovers assets by directory scan — filenames must match exactly.

-
-## Iteration Workflow
-
-For each asset, generate 4-6 candidates:

-6. Select the best candidate, trim, normalize, convert.
-
-## Post-Processing
-
-After selecting the best generation:
-
-```bash
-# Trim silence from start/end
-ffmpeg -i input.wav -af "silenceremove=start_periods=1:start_silence=0.1:start_threshold=-50dB,areverse,silenceremove=start_periods=1:start_silence=0.1:start_threshold=-50dB,areverse" trimmed.wav
-
-# LUFS normalize to -16 LUFS (broadcast standard, good for game audio)
-ffmpeg -i trimmed.wav -af loudnorm=I=-16:LRA=11:TP=-1 normalized.wav
-
-# Convert to .ogg for Godot
-ffmpeg -i normalized.wav -c:a libvorbis -q:a 6 output.ogg
-
-# For loops: verify loop point
-ffplay -loop 0 output.ogg
-```
-
-For ambient loops, create crossfade overlap:
-```bash
-# Create a 45s loop with 3s crossfade overlap
-# (manual: export 48s, crossfade first 3s with last 3s in Audacity)
-```
-
-## Manual Synthesis (Insert-Tech Sounds)
-
-For sounds under 200ms (cursor hover, weapon aim), Stable Audio Open cannot
-produce meaningful output. Use manual synthesis instead:
-
-```python
-# Example: 50ms cursor hover tick
-import numpy as np
-import wave
-
-sr = 44100
-duration = 0.05  # 50ms
-t = np.linspace(0, duration, int(sr * duration), endpoint=False)
-freq = 3200  # Hz
-signal = np.sin(2 * np.pi * freq * t)
-envelope = np.exp(-t * 80)  # exponential decay
-audio = (signal * envelope * 32767).astype(np.int16)
-
-with wave.open("cursor_hover.wav", "w") as f:
-    f.setnchannels(1)
-    f.setsampwidth(2)
-    f.setframerate(sr)
-    f.writeframes(audio.tobytes())
-```
-
-## Quality Checklist
-
-After generating, verify:
- Sound matches the sonic family (insert-tech = synthetic/precise, organic = warm/natural)
- Frequency range doesn't mask other layers (check docs/assets/audio/palette.md)
- Duration matches spec
- No unwanted artifacts (clicks, pops, digital noise at start/end)
- Loop point is clean (ambient loops only)
- Volume sits well relative to other assets (LUFS normalized)
- Passes the close-your-eyes test
-
-## File Placement
-
-Generated assets go to `client/assets/audio/` with exact filenames from the
-asset docs:
-
-```
-client/assets/audio/
-  amb_station_base.ogg       # Ambient bus
-  amb_workplace_layer.ogg    # Ambient bus

+##   - Entity tint fades 0.5-1s to new relationship color on confrontation delivery
+##   - Cursor hover tint also updates to match relationship
+##   - Palette matches D-033 exactly
+##
+## Tests are structured in layers:

+##   2. Relationship-to-color mapping — tests the lookup function
+##   3. Entity renderer relationship coloring — tests that entities USE relationship
+##   4. Tween on relationship change — tests fade behavior (0.5-1s)
