Summarize the current diff per file as markdown: a `## <filepath>` heading per changed file followed by a prose summary of its changes. Triggers: /changes, "summarize the diff", "what changed per file", "per-file summary of changes", "суммаризируй дифф", "что изменилось по файлам". Skip for reviewing quality or bugs (use /code-review) and for raw diff output (plain `git diff`).
Compress an expository note into readable prose backed by a certified Glossary via a standalone CLI — abstractive idea-compression, not extractive trimming. Re-expresses the note as flowing prose (carrying the thesis and the relations among terms) above an optional `## Workflow` checklist of the note's actionable directives and a definitions-only `## Glossary` table, collapsing restatements to one entry each and keeping only operational tokens verbatim; a different model fidelity-grades the glossary definitions and the workflow steps against the source and surfaces anything that did not translate. Replaces /cut. Use on /distill, "distill this", "compress this note", "make a glossary of this note", "tighten this into its ideas", "summarize as a glossary", "compress this guide/procedure into steps", "this note is too long/verbose", «дистиллируй», «сократи в глоссарий», «выжимка», «сделай глоссарий», «сократи гайд в шаги»; route whole-repo glossary maintenance to /glossary.
Route the current context to one expert persona and return that lens's candid second opinion. Auto-classifies to the best-fit persona, or name one explicitly. Runs the persona as a spawned subagent so its reasoning stays out of the main context. Roster spans engineering, product, go-to-market, and craft. Out of scope: generating new designs (use /design), arguing both sides (use /debate), stress-testing one plan (use /probe), scoring confidence in a claim (use /grade). Invoke explicitly with /opinion.
Personal knowledge management in an Obsidian vault. Use whenever the user wants to save, find, review, or organize knowledge, even without saying "vault". Triggers: saving links/articles as references, distilling concepts into cards, writing original notes, searching or quizzing saved content, listing active projects ("what am I working on"), explicit /vault commands, weekly-log operations (backlog/бэклог, planning, completing tasks, sleep). Excludes direct file edits not routed through /vault (editing a .md file in a code repo that is not a vault artifact), Obsidian app features (kanban, canvas, plugins, .base), web search. Skip for session save/resume ("wrapping up", "where did we leave off") — use /track.
Test an existing thing's behavior against a falsifiable claim and capture the result as a standalone Markdown record in the current working directory. Self-contained — no vault, no external templates, no project linking. Triggers: /experiment, "run an experiment", "test this claim", "verify whether", "does X actually", "check if X works", "is X true", "falsifiable claim".
