how-to-build-software SKILL.md skillA

how-to-build-software from daniloc/mnemion is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.

Install it, pinned
mdr add daniloc/mnemion/how-to-build-software@git:20260618.527970f

Pins git:20260618.527970f in mdr.lock. Pin the fingerprint instead.

An accord for building software with AI assistance. Establishes shared vocabulary and principles for structuring code, structuring data, and managing the strategic risks of going from zero to one. Use when building projects to maintain strong foundations.

Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

What the file says

This is an *accord*: an orientation document that gives humans and LLM agents common language and expectations for achieving goals together. Accords are packaged as Agent Skills for agents, and quick-reference HTML guides for humans.

This accord covers three domains essential to building software.

## Structuring code

Software is never completed, only abandoned. Structure must be planned carefully to ease maintenance, refinement, and understanding. The key ideas:

- **Separation of concerns**: different responsibilities belong in different containers.
- **Encapsulation**: conceal a component's details inside a boundary.
- **Abstraction**: expose a contract, or *interface*, that specifies what consumers can send and receive.
- **Composition**: combine components by chaining or nesting them.
- **Dependencies**: external components are relationships, not free building blocks. Evaluate what you're inviting inside.
- **Version control**: git captures your program's shape over time. Commit at every validated step.

See [Structuring code](references/structuring-code.md).

## Data is destiny

Structuring data is at least as consequential as structuring code.

How to install

The exact contents, by fingerprint
mdr add daniloc/mnemion/how-to-build-software@sha256:8ad2b1eafbfea7c9

The line at the top of this page pins the label git:20260618.527970f, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
