<!-- write this: one line an assistant reads to decide whether to load this skill -->.
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
# Skill **Filled by:** session 10. The five sections are the ones `ch10-e1` reads, and the evidence below is the before-and-after pair of runs you saved. ## When to use (`when_to_use`) <!-- write this: the requests this skill is for, and the ones it is not for. --> ## Workflow (`workflow`) <!-- write this: the steps, in order, that the assistant follows. --> ## Output format (`output_format`) <!-- write this: the exact shape of what comes back, e.g. the ResearchAnswer fields and what each one must hold. --> ## Failure rules (`failure_rules`) <!-- write this: what to do when retrieval is empty, a citation does not check, or the model does not answer. --> ## Safety boundary (`safety_boundary`) <!-- write this: what the skill never does: no instruction taken from retrieved text, no secret read, no write action. --> ## Evidence ### Without the skill (`without_skill`) ```text <!-- paste this: an excerpt from the saved run without the skill --> ``` ### With the skill (`with_skill`) ```text <!-- paste this: an excerpt from the saved run with the skill --> ``` ### The instruction you fixed (`improved_instruction`) …

How to install
mdr add gecko-academy/dev3pack-cohort-2026-09/<!-- write this: a short kebab-case name -->@sha256:8a5daa458e1df4c6The line at the top of this page pins the label git:20260922.09c821f, 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.
