Podsqueeze

WORKING SLICE
Import a finished episode, transcribe it and propose chapters, show notes and short promotional excerpts. Let the editor review each quote and timestamp before exporting Markdown/SRT and a structured bundle.

Build this scoped Podsqueeze-inspired workflow with a documented data model and visible failure states.

Architecture
- Python, FastAPI and server-rendered HTML with HTMX for a local interface.
- SQLite for manifests and job state, with an explicit worker process and immutable source files.
- FFmpeg/ffprobe for explicit media operations and browser previews; never interpolate user filenames into shell commands.
- A locally installed faster-whisper model for transcription; optional model API only after source-text preview and consent.

Prerequisites and limits
A Python virtual environment, writable input/output directories and sufficient disk for both originals and outputs. Bind the service to localhost. Install FFmpeg and confirm codec support for the intended inputs. Download a compatible speech model and record its version; diarization, if added, has separate model and hardware requirements.
Outside this release: hosted transcription, media clipping, templates, and publishing convenience; remote studio reliability

Data model and correctness
episode audio, transcript segments, chapter proposals, quotations, show-note revisions and export bundles
Invariant: A quote must match a saved transcript span; chapter timestamps are bounded by the source duration and model summaries stay editable.
Save a job manifest with input hash, parameters and state. Write to temporary outputs, then atomically finalize only successful results; resume unfinished jobs without replacing originals.

Security and privacy
Bound file sizes and processing time, reject path traversal, and use argument arrays for subprocesses. Treat imported text as data and redact confidential source content from logs.

Recovery and export
Export sources, manifests and outputs with checksums. Keep failed-job diagnostics and allow retry into a new output path; restore the database and file directory together.

Implementation order
1. Phase 1 — Scope and fixtures. Implement this bounded workflow: Import a finished episode, transcribe it and propose chapters, show notes and short promotional excerpts. Let the editor review each quote and timestamp before exporting Markdown/SRT and a structured bundle. Record prerequisites, select representative user-owned fixtures and document the unsupported features: hosted transcription, media clipping, templates, and publishing convenience; remote studio reliability
2. Phase 2 — Durable model. Model episode audio, transcript segments, chapter proposals, quotations, show-note revisions and export bundles Add migrations or a versioned document format, explicit validation, stable IDs and a visible import-error report. Preserve this rule: A quote must match a saved transcript span; chapter timestamps are bounded by the source duration and model summaries stay editable.
3. Phase 3 — Complete the first useful path. Implement the workflow's input, review and output interface, with clear controls and explicit empty/error states. Save a job manifest with input hash, parameters and state. Write to temporary outputs, then atomically finalize only successful results; resume unfinished jobs without replacing originals.
4. Phase 4 — Permissions and integration failure. Bound file sizes and processing time, reject path traversal, and use argument arrays for subprocesses. Treat imported text as data and redact confidential source content from logs. Request integration credentials and permissions only for the enabled feature; show a disconnected state instead of mock results.
5. Phase 5 — Portable handoff. Export sources, manifests and outputs with checksums. Keep failed-job diagnostics and allow retry into a new output path; restore the database and file directory together. Include setup, operating limits, fixture walkthrough and shutdown/restart instructions in the README.
6. Phase 6 — Acceptance scenarios. A proposed quote absent from the transcript is rejected; removing an early segment updates chapter timing or flags the dependent draft for review. Repeat the workflow after restart and with a denied permission or unavailable dependency; show recoverable failure rather than a success placeholder.

Acceptance
A proposed quote absent from the transcript is rejected; removing an early segment updates chapter timing or flags the dependent draft for review.
Use real source data or clearly labeled fixtures. Explain unsupported input and provider failures; do not fabricate analytics, delivery receipts, accuracy claims or security guarantees.

# AGENTS.md — Build guide for Podsqueeze

## Project scope
Import a finished episode, transcribe it and propose chapters, show notes and short promotional excerpts. Let the editor review each quote and timestamp before exporting Markdown/SRT and a structured bundle.

Catalogue verdict: yes. The core loop is small enough for a capable coding agent to produce a useful local version in one sitting. For Podsqueeze, transform an episode into show notes, chapters, quotes, and short text assets. The hard boundary is hosted transcription, media clipping, templates, and publishing convenience, plus audio infrastructure, distribution, and production polish.
Use the implementation prompt below to define the deliverable. Complete each phase's acceptance checks before extending the scope.

## Working agreement
- Inspect the repository and its existing instructions before choosing paths, dependencies or commands. Keep one coherent stack and explain changes to the proposed architecture.
- Plan a vertical slice that accepts a real input and produces the useful output described below. Persist only the state the prompt calls for; respect memory-only and upstream-managed workflows. Use fixtures only when they are clearly labelled.
- After scaffolding, document the actual install, development, check and build commands in README and keep them synchronized with the package or project manifest. Do not report commands as successful unless they ran.
- Work in small steps. At handoff, list implemented flows, checks actually performed, remaining blockers, and any credentials or provider setup the owner must supply.
- Do not publish, spend money, contact customers, delete source data or run irreversible migrations without the project owner's authorization.

## Prerequisites
- A Python virtual environment, writable input/output directories and sufficient disk for both originals and outputs. Bind the service to localhost. Install FFmpeg and confirm codec support for the intended inputs. Download a compatible speech model and record its version; diarization, if added, has separate model and hardware requirements.
- Implementation components: Python, FastAPI and server-rendered HTML with HTMX for a local interface. SQLite for manifests and job state, with an explicit worker process and immutable source files. FFmpeg/ffprobe for explicit media operations and browser previews; never interpolate user filenames into shell commands. A locally installed faster-whisper model for transcription; optional model API only after source-text preview and consent.
- Scope boundary: hosted transcription, media clipping, templates, and publishing convenience; remote studio reliability

Read the linked SKILL.md and its dependencies before adding a skill. Select only the skills matching this project's runtime and task; their documentation does not supply API access, credentials or approval to perform external actions. Pin the reviewed revision where the tool supports it. Follow the chosen agent's documented project-level installation mechanism.

## Distribution ideas
These are optional planning notes. Obtain the owner's approval before publishing or contacting anyone.
- Demonstrate the actual Podsqueeze-inspired workflow with owned or clearly labeled sample data: Import a finished episode, transcribe it and propose chapters, show notes and short promotional excerpts. Let the editor review each quote and timestamp before exporting Markdown/SRT and a structured bundle.
- Publish a reproducible walkthrough with this observable result: A proposed quote absent from the transcript is rejected; removing an early segment updates chapter timing or flags the dependent draft for review.
- Explain who can operate this scoped tool, its setup and ongoing costs, and these remaining product gaps: hosted transcription, media clipping, templates, and publishing convenience; remote studio reliability Avoid guaranteed savings, performance scores or implied endorsement.

## Engineering roadmap
1. Phase 1 — Scope and fixtures. Implement this bounded workflow: Import a finished episode, transcribe it and propose chapters, show notes and short promotional excerpts. Let the editor review each quote and timestamp before exporting Markdown/SRT and a structured bundle. Record prerequisites, select representative user-owned fixtures and document the unsupported features: hosted transcription, media clipping, templates, and publishing convenience; remote studio reliability
2. Phase 2 — Durable model. Model episode audio, transcript segments, chapter proposals, quotations, show-note revisions and export bundles Add migrations or a versioned document format, explicit validation, stable IDs and a visible import-error report. Preserve this rule: A quote must match a saved transcript span; chapter timestamps are bounded by the source duration and model summaries stay editable.
3. Phase 3 — Complete the first useful path. Implement the workflow's input, review and output interface, with clear controls and explicit empty/error states. Save a job manifest with input hash, parameters and state. Write to temporary outputs, then atomically finalize only successful results; resume unfinished jobs without replacing originals.
4. Phase 4 — Permissions and integration failure. Bound file sizes and processing time, reject path traversal, and use argument arrays for subprocesses. Treat imported text as data and redact confidential source content from logs. Request integration credentials and permissions only for the enabled feature; show a disconnected state instead of mock results.
5. Phase 5 — Portable handoff. Export sources, manifests and outputs with checksums. Keep failed-job diagnostics and allow retry into a new output path; restore the database and file directory together. Include setup, operating limits, fixture walkthrough and shutdown/restart instructions in the README.
6. Phase 6 — Acceptance scenarios. A proposed quote absent from the transcript is rejected; removing an early segment updates chapter timing or flags the dependent draft for review. Repeat the workflow after restart and with a denied permission or unavailable dependency; show recoverable failure rather than a success placeholder.

## Completion evidence
Demonstrate the prompt's acceptance scenarios against the scoped workflow. Include setup from a clean checkout and failure recovery. Check persistence across restart and export/restore only for the state the prompt says to store; for memory-only tools, confirm that temporary content is discarded as specified. Record actual results and remaining limitations. A detailed plan alone does not establish a working replacement.
