If missing, ask the user to set it locally (do not ask them to paste the key).</li>\n<li>Run the bundled <code>transcribe_diarize.py</code> CLI with sensible defaults (fast text transcription).</li>\n<li>Validate the output: transcription quality, speaker labels, and segment boundaries; iterate with a single targeted change if needed.</li>\n<li>Save outputs under <code>output/transcribe/</code> when working in this repo.</li>\n</ol>\n<h2>Decision rules</h2>\n<ul>\n<li>Default to <code>gpt-4o-mini-transcribe</code> with <code>--response-format text</code> for fast transcription.</li>\n<li>If the user wants speaker labels or diarization, use <code>--model gpt-4o-transcribe-diarize --response-format diarized_json</code>.</li>\n<li>If audio is longer than ~30 seconds, keep <code>--chunking-strategy auto</code>.</li>\n<li>Prompting is not supported for <code>gpt-4o-transcribe-diarize</code>.</li>\n</ul>\n<h2>Output conventions</h2>\n<ul>\n<li>Use <code>output/transcribe/&lt;job-id&gt;/</code> for evaluation runs.</li>\n<li>Use <code>--out-dir</code> for multiple files to avoid overwriting.</li>\n</ul>\n<h2>Dependencies (install if missing)</h2>\n<p>Prefer <code>uv</code> for dependency management.</p>\n<pre><code>uv pip install openai\n</code></pre>\n<p>If <code>uv</code> is unavailable:</p>\n<pre><code>python3 -m pip install openai\n</code></pre>\n<h2>Environment</h2>\n<ul>\n<li><code>OPENAI_API_KEY</code> must be set for live API calls.</li>\n<li>If the key is missing, instruct the user to create one in the OpenAI platform UI and export it in their shell.</li>\n<li>Never ask the user to paste the full key in chat.</li>\n</ul>\n<h2>Skill path (set once)</h2>\n<pre><code>export CODEX_HOME=\"${CODEX_HOME:-$HOME/.codex}\"\nexport TRANSCRIBE_CLI=\"$CODEX_HOME/skills/transcribe/scripts/transcribe_diarize.py\"\n</code></pre>\n<p>User-scoped skills install under <code>$CODEX_HOME/skills</code> (default: <code>~/.codex/skills</code>).</p>\n<h2>CLI quick start</h2>\n<p>Single file (fast text default):</p>\n<pre><code>python3 \"$TRANSCRIBE_CLI\" \\\n  path/to/audio.wav \\\n  --out transcript.txt\n</code></pre>\n<p>Diarization with known speakers (up to 4):</p>\n<pre><code>python3 \"$TRANSCRIBE_CLI\" \\\n  meeting.m4a \\\n  --model gpt-4o-transcribe-diarize \\\n  --known-speaker \"Alice=refs/alice.wav\" \\\n  --known-speaker \"Bob=refs/bob.wav\" \\\n  --response-format diarized_json \\\n  --out-dir output/transcribe/meeting\n</code></pre>\n<p>Plain text output (explicit):</p>\n<pre><code>python3 \"$TRANSCRIBE_CLI\" \\\n  interview.mp3 \\\n  --response-format text \\\n  --out interview.txt\n</code></pre>\n<h2>Reference map</h2>\n<ul>\n<li><code>references/api.md</code>: supported formats, limits, response formats, and known-speaker notes.</li>\n</ul>\n","files":[{"path":"agents/openai.yaml","sizeBytes":414,"isText":true},{"path":"assets/transcribe.png","sizeBytes":1288,"isText":false},{"path":"assets/transcribe-small.svg","sizeBytes":750,"isText":false},{"path":"LICENSE.txt","sizeBytes":10776,"isText":true},{"path":"references/api.md","sizeBytes":457,"isText":true},{"path":"scripts/transcribe_diarize.py","sizeBytes":8684,"isText":true},{"path":"SKILL.md","sizeBytes":2834,"isText":true}],"reviewScore":null,"reviewSummary":null,"trust":{"provenance":"trusted-source-unreviewed","notice":"Community-authored content, reproduced verbatim and not vetted as instructions.
