Adds the shared caveman communication-mode skill at .claude/skills/caveman/SKILL.md so it is available consistently across all container-registry repos. Content is the canonical copy from the shared skills setup, unchanged.

This PR adds a communication mode whose current guidance could overstate certainty and describe destructive database operations inaccurately. The impact is limited to generated explanations, so it is mergeable with explicit owner awareness and follow-up to correct these warnings.

## Rules

Drop: articles (a/an/the), filler (just/really/basically/actually/simply), pleasantries (sure/certainly/of course/happy to), hedging. Fragments OK. Short synonyms (big not extensive, fix not "implement a solution for"). Abbreviate common terms (DB/auth/config/req/res/fn/impl). Strip conjunctions. Use arrows for causality (X -> Y). One word when one word enough.

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win

Preserve meaningful uncertainty.

When hedging expresses confidence, assumptions, or missing evidence, do not remove it. That qualifier is technical substance. Otherwise caveman mode can turn “may” or “likely” into a definitive claim and violate the full-accuracy requirement.

Proposed wording
-Drop: articles (a/an/the), filler (just/really/basically/actually/simply), pleasantries (sure/certainly/of course/happy to), hedging.
+Drop: articles (a/an/the), non-substantive filler (just/really/basically/actually/simply), pleasantries (sure/certainly/of course/happy to). Preserve uncertainty, assumptions, and conditions.

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win

Make the destructive-operation warning database-accurate.

DROP TABLE users; removes the table definition and its rows, not only the rows. “Cannot be undone” is database-dependent because transaction rollback or backup recovery may exist. State the exact effect and qualify recovery.

Proposed wording
-> **Warning:** This will permanently delete all rows in the `users` table and cannot be undone.

<violation number="1" location=".claude/skills/caveman/SKILL.md:14">
P3: The Persistence rule states caveman is off only when the user says stop caveman or normal mode, and that it never reverts, which conflicts with the later Auto-Clarity Exception that tells the model to drop caveman temporarily for security warnings and irreversible-action confirmations. A strict instruction-follower could read the absolute off-only wording as prohibiting the temporary drop, which matters most for the safety-critical cases the exception is meant to protect. Clarify that persistence governs permanent deactivation while the exception permits a temporary pause.</violation>

## Persistence

ACTIVE EVERY RESPONSE once triggered. No revert after many turns. No filler drift. Still active if unsure. Off only when user says "stop caveman" or "normal mode".
