write-skills SKILL.md skillA

write-skills from dzhng/skills is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.

Install it, pinned
mdr add dzhng/skills/write-skills@git:20261004.3e02e02

Pins git:20261004.3e02e02 in mdr.lock. Pin the fingerprint instead.

Create or revise agent skills. Use when adding a new skill file, renaming a skill, simplifying an existing skill, improving trigger descriptions, or deciding what belongs in a skill versus references, scripts, assets, or ordinary docs.

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

# Write Skills

A skill is not documentation. It is compressed operational memory for an
agent that already knows how to code and reason. Its job is
**predictability** — the agent taking the same *process* every run, not
producing the same output. Put only the context that changes what the agent
will do.

## First Principles

1. **Trigger from the description.** The frontmatter `description` is the
   only part read before the skill loads. Say what the skill does and the
   concrete situations that should trigger it. Do not hide trigger rules in
   the body.

2. **Spend tokens like they are scarce.** Assume the agent is already good at
   general reasoning. State the direction and let smart models figure out
   implementation details. A wrapper skill can be two sentences: name the
   capability to use and the skill to follow. Add mechanics only when a
   demonstrated failure requires them.

3. **Write procedures, not essays.** Prefer imperative rules, decision
   points, and small examples. A good skill changes behavior in the next
   turn; it does not merely explain the topic. And match the procedure to
   the deliverable's shape: a catalog of techniques with "pick what fits"

How to install

The exact contents, by fingerprint
mdr add dzhng/skills/write-skills@sha256:3bacf02ad5bf749e

The line at the top of this page pins the label git:20261004.3e02e02, 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.
