Use when a skill, agent prompt, or rules document has grown long, repetitive, or self-contradicting and must get shorter without changing the behavior it produces, or when an already-compressed doc must be checked for lost rules before merge.
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
# Compacting Skills ## Overview The current doc is the specification. Compression may remove only what you can show the agent will still do without it. Size is the outcome, never the goal: the deliverable is the same behavior from fewer words, with evidence. Three kinds of evidence are required, because each misses what the others catch: | Evidence | Catches | Misses | |---|---|---| | Rule inventory + trace table | a rule that vanished | a rule that changed scope; behavior | | Scenario measurement (before/after, 5 reps) | behavior drift on asked questions | gaps between sentences; unasked cases | | Compression regression audit | widened/narrowed rules, deleted premises, doc/code mismatch | nothing alone proves behavior | A pilot compression scored 0.997 on its scenarios (baseline 0.960) and still carried 10 regressions that only the audit found, plus one more an external reviewer found. Never stop at the score. **REQUIRED BACKGROUND:** writing-skills (scenario testing with subagents). ## What stays, what goes Keep a rule (MUST) when at least one holds, and record which: …

How to install
mdr add toongri/oh-my-toong-playground/compacting-skills@sha256:49d8e4fdfc4ce5aaThe line at the top of this page pins the label git:20261022.0d15fd3, 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.
