- Typst or a LaTeX install if you want PDF out
Delivery order
Scaffold the smallest runnable application and document its commands.
done whenThe project starts from a documented command in a clean checkout.
Implement the primary data model and core workflow.
done whenThe main object can be created, read and changed end to end.
Add validation, safe failure states, and persistence.
done whenBad input is refused with a readable message and nothing is left corrupted.
Cover the critical path with automated tests.
done whenThe highest-risk behavior fails the suite when it breaks.
Exercise a clean install from the README and fix every missing step.
done whenA fresh clone reaches the first successful workflow using only the README.
That is the whole plan for FileChanger. What it deliberately does not cover is below · check the gaps before you call it a replacement.
- sandboxing, because your version runs files straight through the same toolchain as everything else on the machine
- the long tail of format pairs, where the fix is usually a missing font, a filter flag or an upstream bug
- queueing and timeouts for large video, which is where the compute bill actually lives
- a hosted MCP server and API keys your other tools can reach from anywhere, not just from localhost
- somebody else being on call when a LibreOffice or LaTeX upgrade quietly breaks PDF output
