prompt-cache-skills

Aider uses 5min TTL by default and works around long pauses with keepalive pings. Wire up the 1h TTL beta instead.

Aider's --cache-prompts is off by default. Flip it on for supported models.

Stop Cline from burning a cache breakpoint on the volatile current user message every turn.

Cline OpenAI native provider sends no prompt_cache_key. Add a stable per-task key so cached_tokens stops being zero.

Cline's system prompt includes a timestamp that may be recomputed per request, invalidating the system-prompt cache.

Continue's prompt caching is opt-in via config and off by default. Flip the default to systemAndTools.

Continue inherits the Cline-family volatile-message cache bug. Same fix shape.

Continue's Gemini provider doesn't use the cachedContents API at all. Add explicit caching for sessions over the minimum token threshold.

OpenCode places cachePoint on Bedrock messages containing DocumentBlocks, which produces a "nothing available to cache" error.

OpenCode's caching detection misses OpenAI-compatible proxies routing to Anthropic/Bedrock. Broaden the predicate.

OpenCode doesn't set prompt_cache_key for Mistral models, missing the documented 10% cached-token discount.

Roo Code's Bedrock provider silently disables caching for custom ARNs. Populate cachableFields to fix.

Roo Code inherits Cline's volatile-message cache bug. Same fix shape, inline location.

One-line description of what this fix does and why it matters.
