Skills as MCP Prompts

All 21 skills are now discoverable via prompts/list and retrievable via prompts/get. Any MCP client (Cursor, Windsurf, Zed, etc.) can discover and invoke agent-lsp's workflow skills without manual installation. prompts/list returns short descriptions (minimal context cost); full workflow instructions load on demand. Skills continue to work as AgentSkills slash commands in parallel. Skill definitions are embedded in the binary at build time.

Critical Fix: progressMu Deadlock

WaitForWorkspaceReadyTimeout locked progressMu at entry but did not unlock on timeout or normal exit paths. When get_change_impact processed multiple files, gopls emitted $/progress notifications that required progressMu in readLoop. The held lock deadlocked the entire read pipeline, blocking all pending requests indefinitely. Root cause of every multi-file get_change_impact hang. Fixed with defer progressMu.Unlock().

Reliability

• Process lifecycle cleanup. Fixed orphaned gopls/pyright processes accumulating across sessions. Shutdown() now waits up to 3 seconds then force-kills. resolver.Shutdown() runs on every exit path (stdin EOF, context cancelled, signal, panic). StartForLanguage shuts down the previous client before starting a new one.
• Stdin pipe deadlock fix. writeRaw now uses a dedicated write mutex instead of the shared state mutex. Prevents deadlock when concurrent reference queries fill the OS pipe buffer.
• Daemon broker context propagation. Forwarded requests use the broker's lifecycle context instead of context.Background().
• Windows build fix. Extracted Setsid into platform-specific files. Daemon mode is not yet supported on Windows; builds no longer fail.

Performance

• Per-symbol timeout in get_change_impact. Each reference query capped at 15 seconds. Timed-out symbols are skipped with a warning.
• Overall get_change_impact timeout. 90-second cap on the entire operation.
• Concurrency bump. Worker pool increased from 8 to 16 parallel reference queries.

Observability

• Per-tool latency logging. Every tool call logs duration via addToolWithPhaseCheck. Calls exceeding 5 seconds log at WARNING. Process start/exit events include PID and uptime.

Tests

224 new tests across 12 packages. Two packages at 100% coverage (internal/uri, internal/extensions). internal/logging at 95%.
