myco SKILL.md skillA
This file is byte-identical to the first copy the registry indexed. Same content hash, so the same checks give both the same grade.
myco from goondocks-co/myco is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add goondocks-co/myco/myco@git:20261023.eab20e6Pins git:20261023.eab20e6 in mdr.lock. Pin the fingerprint instead.

Myco is this project's memory — the sessions that happened, the durable observations (spores) drawn from them, and the plans. It holds why the code is the way it is, which the code itself cannot show. Use it before a design decision, when debugging something non-obvious, when a structure looks arbitrary, when picking up work someone else started, and after learning something worth keeping.
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
# Myco
The codebase shows **what** exists. Myco shows **why**: the approach chosen over the alternatives, the thing that broke, the constraint that is not visible in the file you are reading.
## The one rule that will bite you
Every Myco tool takes a **`project`** argument — a project id, or the repository's git remote.
- A **read** without it uses the project your credential is bound to. Usually right; wrong the moment you are working across repositories.
- A **write** without it is **refused**. This is deliberate: a credential can reach more than one project, and an unnamed write would land wherever the connection happened to point.
- An argument the tool's schema does not declare is refused by name.
`myco_cortex` with `op: "instructions"` answers this project's standing guidance **and its project id**. That id is the value to pass as `project`. If you were given Myco context at session start, the id is already in it.
## Reading
Search first, then fetch what you want in full by its id. Search previews are one line per hit; they are for choosing, not for reading.
```
myco_search { "query": "why the outbox drains on a lease" }

How to install
mdr add goondocks-co/myco/myco@sha256:80a09b5015981fc5The line at the top of this page pins the label git:20261023.eab20e6, 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.
