upmd turns fenced code blocks in a Markdown file into runnable tasks. You can run a single named block, work through tasks in a terminal UI, or execute a dependency-aware workflow from a CLI or CI job. It is useful when you want operational instructions and the commands that carry them out to live together in one document.
How upmd treats Markdown as a workflow
In upmd, a fenced code block can be a task rather than just an example. Add a name attribute to address a block directly, and use deps to declare which tasks must run first. The README’s example builds a workflow with build, then lint and test depending on it, followed by verify depending on both. See the upmd README for the project’s syntax and examples.
Dependencies determine staging: tasks separated by | share a stage, while commas begin a later stage. A failure skips later stages. With --all, unrelated tasks can continue despite a failure, but the overall command still exits non-zero. This is useful when independent checks should finish even if one branch fails.

#1 Best Overall
- Read Before You Buy — No Video Output: These adapters support charging and USB 2.0 data transfer, but cannot transmit video signals. Except for standard USB webcams (which use USB data only), they are not compatible with HDMI/DisplayPort cables, video-capable USB-C hubs, or docking stations with video output.
- Convert USB-A Ports to USB-C: Designed to connect USB-C earphones, cables, flash drives, card readers, and other USB-C accessories to standard USB-A ports. Plug-and-play with no drivers or software required.
- Aluminum Alloy Housing: Built with a sturdy aluminum alloy shell that aids in heat dissipation and protects against daily wear and scratches. Designed to maintain a stable and secure connection.
- Compact & Travel-Friendly: The ultra-compact design allows the adapter to stay plugged into your device without blocking adjacent ports or adding bulk, reducing wear and tear on your original USB ports.
- 12-Month Warranty: Backed by a 12-month manufacturer warranty for peace of mind. Designed to meet strict quality control standards for reliable everyday performance.

Explore tasks in a terminal UI
The project documents a terminal interface for navigating and searching blocks, running selected tasks, inspecting full output, and sending input to a running task. This mode suits documents where you want to inspect the commands and their output while working through them.
Rank #2

Execution context, supported languages, and state
upmd says tasks run in a real pseudo-terminal, which is intended to support interactive prompts, colors, editors, and pagers. That differs from treating every block as a simple non-interactive command; whether a particular program behaves as expected still depends on its own requirements and your environment.
The README lists built-in runners for these languages and shells:
Rank #4
- Dual Converters, Infinite Potential：Includes 2× USB C male to USB A female adapters and 2× USB A male to USB C female adapters. Perfect for a wide range of uses—tablets with Bluetooth keyboards, expand USB ports on macbook, and more. Two different converters for all your daily needs
- Next-Level 10Gbps & 3A Charging: No more slow 480Mbps, this usb to usb c adapter has a transfer speed of up to 10Gbps, allowing you to do more transferring in less time. This usb adapter fits both USB A and USB C charger, supporting up to 3A fast charging
- Upgraded Exquisite Craftsmanship: With an aluminum alloy housing and metal connector, the usbc to usb adapter is extremely durable and sturdy. Rigorously tested to withstand more than 10,000 times of plugging and unplugging, ensuring long-lasting performance

When upmd is a good fit
upmd is worth considering when a Markdown document should function as both explanation and an executable operational workflow. Its named tasks and dependency stages are especially relevant when a procedure has prerequisites or independent checks, while the terminal UI is useful for running blocks interactively. For automation, the CI mode and non-zero failure behavior provide a documented path to run workflows from a job.
Before adopting it, check whether your workflow depends on interactive terminal behavior, cross-task shell state, or one of the experimental language state-capture features. The project documents these capabilities, but the available official material does not provide independent performance, reliability, or comparison data against other Markdown task tools.
