badlogic/pi-mono v0.59.0 on GitHub

Faster startup by lazy-loading @mariozechner/pi-ai provider SDKs on first use instead of import time (#2297)
Better provider retry behavior when providers return error messages as responses (#2264)
Better terminal integration via OSC 133 command-executed markers (#2242)
Better Git footer branch detection for repositories using reftable storage (#2300)

Changed custom tool system prompt behavior so extension and SDK tools are included in the default Available tools section only when they provide promptSnippet. Omitting promptSnippet now leaves the tool out of that section instead of falling back to description (#2285)

Lazy-load built-in @mariozechner/pi-ai provider modules and root provider wrappers so coding-agent startup no longer eagerly loads provider SDKs before first use (#2297)

Fixed session title handling in /tree, compaction, and branch summarization so empty title clears render correctly and session_info entries stay out of summaries (#2304 by @aliou)
Fixed footer branch detection for Git repositories using reftable storage so branch names still appear correctly in the footer (#2300)
Fixed rendered user messages to emit an OSC 133 command-executed marker after command output, improving terminal prompt integration (#2242)
Fixed provider retry handling to treat provider-returned error messages as retryable failures instead of successful responses (#2264)
Fixed Claude 4.6 context window overrides in bundled model metadata so coding-agent sees the intended model limits after generated catalogs are rebuilt (#2286)
