how from arjitj2/open-pstack is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add arjitj2/open-pstack/how@git:20261014.daa0fc5Pins git:20261014.daa0fc5 in mdr.lock. Pin the fingerprint instead.

Use for "how does X work", code walkthroughs before changing something, and placement / ownership / layering questions ("where should this live", "which package owns this", "is this the right layer"). Explains subsystem architecture, runtime flow, onboarding mental models. Use why for motivation.
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
# How Explore the codebase to answer "how does X work?" questions. Produce architectural explanations at the level of a senior engineer onboarding onto a subsystem, enough to build a working mental model, not so much that it reads like annotated source code. **Dispatch contract.** Resolve every configured role through [`provider-dispatch.md`](../poteto-mode/references/provider-dispatch.md). Each lane below names a role line in the current harness's pstack model sheet and a default descriptor: use the line's value, or the default when the sheet or the line is missing. `auto` and `inherit-parent` run on the parent model natively. Each lane runs its saved attempt chain: a terminal outcome the sheet's `# fallback` policy authorizes advances to the next saved attempt per provider-dispatch's fallback state machine (`usage-exhausted` only when no policy is saved); every other route failure is a dropout, not a substitution. These lanes are read-only, so an eligible fallback advances directly. On Codex, resolve remaining Claude tool names via [`codex-tools.md`](../poteto-mode/references/codex-tools.md). ## 1.

How to install
mdr add arjitj2/open-pstack/how@sha256:5e84872a0d9bb35eThe line at the top of this page pins the label git:20261014.daa0fc5, 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.
