Skill se použije, když uživatel zadá "/oponent", nebo chce nezávislý oponentský posudek na dokument, který spolu psali – strategii, pozicování, PRD, koncepci, cenotvorbu, datový model, analytickou dokumentaci. Pohled čerstvýma očima z několika hledisek: co nedává smysl, co si odporuje, co nebude fungovat, co chybí.
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
# Oponent ## Co skill dělá Uživatel má hotový nebo rozpracovaný dokument, na kterém jste spolu dlouho pracovali. Právě proto na něj **nemáš nezávislý pohled** – spoluautor nevidí, co v dokumentu chybí, protože to má v hlavě, a nevidí, co je slabé, protože si to sám odsouhlasil. Skill proto pošle na dokument **subagenty bez kontextu téhle session**, každého z jiného hlediska, a jejich nálezy s uživatelem probere jeden po druhém. V *Životním cyklu projektu* (`~/.claude/standards/rules.md`) je to kontrolní krok, ne bod na ose: **stojí ve třech mezerách** – za `/discovery`, za `/specify` a za `/architect`. Do životního cyklu patří proto, že jinak návrh neměří nikdo – `/review` ověřuje kód proti specifikaci, ale samotnou specifikaci nikdo proti ničemu, takže vada v ní projde celým životním cyklem jako korektní. Přeskakuje se stejným pravidlem jako každý jiný krok: drobná změna uvnitř navrženého systému posudek nepotřebuje, nový systém nebo nový podsystém ano – a přeskočení se řekne nahlas i s důvodem. ## Co skill nedělá - **Není to kontrola kódu.** Na kód je `/review`. …

How to install
mdr add jantichy/claude/oponent@sha256:fc84b27aa7560ad8The line at the top of this page pins the label git:20261105.fb301d4, 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.
