define-done SKILL.md skillA
define-done from haabe/mycelium is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add haabe/mycelium/define-done@git:20261008.447b181Pins git:20261008.447b181 in mdr.lock. Pin the fingerprint instead.

Pin a measurable, outcome-based Definition of Done for a diamond — a behaviour-change that creates value, not a build-list. Problem-first Socratic sequence; writes definition_of_done to the diamond at birth or retrofits it when missing.
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
# Define Done
Pin an explicit, outcome-based **Definition of Done** for a diamond. "Done" is *a change in human behaviour that creates value* (Seiden), not "the feature shipped" — you're done when it ships **and** has the intended impact (Amplitude). The diamond's implicit done defaults to the harshest, least-controllable bar ("a user shipped a product"), which is both wrong for validating *purpose* and a demotivation engine. This skill makes the bar explicit, measurable, and pre-committed.
This is distinct from `/mycelium:definition-of-done` (the per-feature agile *quality checklist* run at `close`). This skill sets the **outcome bar a whole diamond is judged against**; that one verifies a feature meets quality criteria. Both can apply.
## When to use
- **At diamond birth** — `/mycelium:interview` (L0) and child-diamond spawn (`/mycelium:diamond-progress`) call this before a diamond is "live."
- **Retrofit** — when `/mycelium:canvas-health`, `/mycelium:diamond-assess`, or the SessionStart nudge flags a diamond with no `definition_of_done`.
- Never silent-fill. The *question* is what produces a real bar ("fits, not ships"); a back-filled field is theatre.

How to install
mdr add haabe/mycelium/define-done@sha256:66cc63bf87bb01daThe line at the top of this page pins the label git:20261008.447b181, 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.
