v0.12.0

Highlights

Reasoning-mode model support

• Preserve reasoning / reasoning_content / reasoning_details across turns so reasoning-mode models (e.g. DeepSeek v4-flash) no longer collapse into malformed text-shaped tool calls.
• Merge streamed reasoning_details fragments by index to avoid duplicated/partial blocks.
• Normalize reasoning_content across assistant messages at send time, including post-compaction history.
• Refactored to an opaque extras dict so future provider-specific fields (Anthropic thinking blocks, etc.) can be added without signature churn.

New extension surfaces

• llm:request and llm:chunk events for wire-level observability (see examples/extensions/wire-log.ts).
• tool-protocol:extract-calls advisable hook for custom tool-call extraction.

TUI fixes

• Render orphaned grouped-tool completions under a (cont.) header.
• Eagerly finalize tool groups when all members complete.
• Stop the spinner before rendering group aggregates / cont. headers (fixes overlap).
• ⎿ labels prefer displayDetail (path / pattern) over the raw tool name.

Subagents

• Budget subagents by completion tokens instead of prompt+completion (fixes premature exhaustion after a few iterations).

Terminal passthrough & startup (#84)

• Parse OSC responses in stdin so tmux queries don't leak into bash.
• Extend string-sequence passthrough to DCS / APC / PM.
• Keep the startup banner in sync with the persisted default model.
• Preserve active mode when a provider re-registration drops it.
• Surface a warning when a saved model is missing from a provider's refreshed catalog.

Robustness

• Recover from tool throws and tighten the auth-error classifier (#82).
• Hard-fail at startup when no agent backend is available, instead of silently degrading (#83).
• Drop ctrl+t thinking label and simplify the OpenRouter default.

Docs

• Reframe README intro as a personal, complementary tool; drop upfront Claude Code name-drop.
• agent-sh -e ... instead of dev-only npm start -- in extension docs; fix stale ExtensionContext import path.
• Add an "Updating" section to the usage guide.

Updating: npm install -g github:guanyilun/agent-sh
