+
+## Other speech models (if requested)
+- `gpt-4o-mini-tts`
+- `tts-1`
+- `tts-1-hd`
+
+## Core parameters
+- `model`: speech model
+- `input`: text to synthesize (max 4096 characters)
+- `voice`: built-in voice name
+- `instructions`: optional style directions (not supported for `tts-1` or `tts-1-hd`)
+- `response_format`: `mp3`, `opus`, `aac`, `flac`, `wav`, or `pcm`
+- `speed`: 0.25 to 4.0
+
+## Built-in voices
+- `alloy`, `ash`, `ballad`, `cedar`, `coral`, `echo`, `fable`, `marin`, `nova`, `onyx`, `sage`, `shimmer`, `verse`
+
+## Output notes
+- Default format is `mp3`.
+- `pcm` is raw 24 kHz 16-bit little-endian samples (no header).
+- `wav` includes a header (better for quick playback).
+
+## Compliance note
+- Provide a clear disclosure that the voice is AI-generated.

+# CLI reference (`scripts/text_to_speech.py`)
+
+This file contains the "command catalog" for the bundled speech generation CLI. Keep `SKILL.md` as overview-first; put verbose CLI details here.
+
+## What this CLI does
+- `speak`: generate a single audio file
+- `speak-batch`: run many jobs from a JSONL file (one job per line)
+- `list-voices`: list supported voices
+
+Real API calls require network access + `OPENAI_API_KEY`. `--dry-run` does not.
+
+## Quick start (works from any repo)
+Set a stable path to the skill CLI (default `CODEX_HOME` is `~/.codex`):
+
+```
+export CODEX_HOME="${CODEX_HOME:-$HOME/.codex}"
+export TTS_GEN="$CODEX_HOME/skills/speech/scripts/text_to_speech.py"
+```
+
+Dry-run (no API call; no network required; does not require the `openai` package):
+
+```
+python "$TTS_GEN" speak --input "Test" --dry-run
+```
+
+Generate (requires `OPENAI_API_KEY` + network):
+
+```
+uv run --with openai python "$TTS_GEN" speak \
+  --input "Today is a wonderful day to build something people love!" \
+  --voice cedar \
+  --instructions "Voice Affect: Warm and composed. Tone: upbeat and encouraging." \
+  --response-format mp3 \
+  --out speech.mp3
+```
+
+No `uv` installed? Use your active Python env:
+
+```
+python "$TTS_GEN" speak --input "Hello" --voice cedar --out speech.mp3
+```
+
+## Guardrails (important)
+- Use `python "$TTS_GEN" ...` (or equivalent full path) for all TTS work.
+- Do **not** create one-off runners (e.g., `gen_audio.py`) unless the user explicitly asks.
+- **Never modify** `scripts/text_to_speech.py`. If something is missing, ask the user before doing anything else.
+
+## Defaults (unless overridden by flags)
+- Model: `gpt-4o-mini-tts-2025-12-15`
+- Voice: `cedar`
+- Response format: `mp3`
+- Speed: `1.0`
+- Batch rpm cap: `50`
+
+## Input limits
+- Input text must be <= 4096 characters per request.
+- For longer text, split into smaller chunks (manual or via batch JSONL).
+
+## Instructions compatibility
+- `instructions` are supported for GPT-4o mini TTS models.
+- `tts-1` and `tts-1-hd` ignore instructions (the CLI will warn and drop them).
+
+## Common recipes
+
+List voices:
+```
+python "$TTS_GEN" list-voices
+```
+
+Generate with explicit pacing:
+```
+python "$TTS_GEN" speak \
+  --input "Welcome to the demo. We'll show how it works." \
+  --instructions "Tone: friendly and confident. Pacing: steady and moderate." \
+  --out demo.mp3
+```
+
+Batch generation (JSONL):
+```
+mkdir -p tmp/speech
+cat > tmp/speech/jobs.jsonl << 'JSONL'
+{"input":"Thank you for calling. Please hold.","voice":"cedar","response_format":"mp3","out":"hold.mp3"}
+{"input":"For sales, press 1. For support, press 2.","voice":"marin","instructions":"Tone: clear and neutral. Pacing: slow.","response_format":"wav"}
+JSONL
+
+python "$TTS_GEN" speak-batch --input tmp/speech/jobs.jsonl --out-dir out --rpm 50
+
+# Cleanup (recommended)
+rm -f tmp/speech/jobs.jsonl
+```
+
+Notes:
+- Use `--rpm` to control rate limiting (default `50`, max `50`).
+- Per-job overrides are supported in JSONL (`model`, `voice`, `response_format`, `speed`, `instructions`, `out`).
+- Treat the JSONL file as temporary: write it under `tmp/` and delete it after the run (do not commit it).

+# Codex network approvals / sandbox notes
+
+This guidance is intentionally isolated from `SKILL.md` because it can vary by environment and may become stale. Prefer the defaults in your environment when in doubt.
+
+## Why am I asked to approve every speech generation call?
+Speech generation uses the OpenAI Audio API, so the CLI needs outbound network access. In many Codex setups, network access is disabled by default (especially under stricter sandbox modes), and/or the approval policy may require confirmation before networked commands run.
+
+## How do I reduce repeated approval prompts (network)?
+If you trust the repo and want fewer prompts, enable network access for the relevant sandbox mode and relax the approval policy.
+
+Example `~/.codex/config.toml` pattern:
+
+```
+approval_policy = "never"
+sandbox_mode = "workspace-write"
+
+[sandbox_workspace_write]
+network_access = true
+```
+
+Or for a single session:
+
+```
+codex --sandbox workspace-write --ask-for-approval never
+```
+
+## Safety note
+Use caution: enabling network and disabling approvals reduces friction but increases risk if you run untrusted code or work in an untrusted repository.

+## Contents
+- Structure
+- Specificity
+- Avoiding conflicts
+- Pronunciation and names
+- Pauses and pacing
+- Iterate deliberately
+- Where to find copy/paste recipes
+
+## Structure
+- Use a consistent order: affect -> tone -> pacing -> emotion -> pronunciation/pauses -> emphasis -> delivery.
+- For complex requests, use short labeled lines instead of a long paragraph.
+
+## Specificity
+- Name the delivery you want ("calm and steady" vs "friendly").
+- If you need a specific cadence, call it out explicitly ("slow and measured", "brisk and energetic").
+
+## Avoiding conflicts
+- Do not mix opposing instructions ("fast and slow", "formal and casual").
+- Keep instructions short: 4 to 8 lines are usually enough.
+
+## Pronunciation and names
+- For acronyms, write the pronunciation hint in text ("A-I" instead of "AI").
+- For names or brands, add a simple phonetic guide in the input text if clarity matters.
+- If a word must be emphasized, add an Emphasis line and repeat the word exactly.
+
+## Pauses and pacing
+- Use punctuation or short line breaks in the input text to create natural pauses.
+- Use the Pauses line for intentional pauses ("pause after the greeting").
+
+## Iterate deliberately
+- Start with a clean base instruction set, then make one change at a time.
+- Repeat critical constraints on each iteration ("keep pacing steady").
+
+## Where to find copy/paste recipes
+For copy/paste instruction templates, see `references/sample-prompts.md`. This file focuses on principles, structure, and iteration patterns.
