Apply the Peter Principle when discussing promotions, career ladders, hiring for leadership roles, why managers sometimes struggle, or how to build healthy engineering organizations. Trigger on phrases like "we promoted our best engineer to manager", "they were great as an IC but struggling as a lead", "how should we think about promotions?", "our managers weren't trained for this", or any situation where promotion or career development decisions intersect with competence and role fit.

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

# Peter Principle

> "People in a hierarchy tend to rise to a level of respective incompetence."
> — Laurence J. Peter, 1969

## The core idea

In most organizations, people are promoted based on performance in their current role. But the skills that make someone excellent in role N are often different from the skills required in role N+1. The result: people keep getting promoted until they reach a role they're not good at — and then they stay there. Everyone ends up at their level of incompetence.

## Why this happens

**Promotion criteria look backward, not forward.**
We promote people for what they've done, not what they can do next. A brilliant individual contributor gets promoted to tech lead because they write great code — but tech lead requires communication, delegation, and conflict resolution, not just coding skill.

**Different roles require genuinely different skills.**
Engineering and management are different jobs. Coding and architecture are different jobs. Building a product and running a product organization are different jobs. The skills don't automatically transfer.

**There's no graceful way back.**

How to install

The exact contents, by fingerprint

mdr add the-artificer-of-ciphers-llc/skills-from-the-artificer/peter-principle@sha256:50027f25db485851

The line at the top of this page pins the label git:20260530.3e17152, 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.
