v0.2.2

Sudo Code v0.2.2

What's New

Features

• ACP slash commands: /compact, /clear, /help, available_commands_update (#547) — scode acp now owns a single slash-command table shared by /help, the unknown-command hint, and a session/update { sessionUpdate: "available_commands_update" } broadcast sent right after every session/new / session/load. /compact mirrors the REPL command (LLM summary first, local heuristic fallback, persisted immediately). /clear resets the session in place — same session id, cwd, model and permission mode — and archives the old transcript as a loadable cleared fork. session/prompt responses carry _meta.sudocode.autoCompacted: true when a turn compacted automatically. /compact runs outside the cwd lease and honours session/cancel.

Fixes

• Compact before a context-window rejection wedges the session (#545) — long ACP sessions used to hit context_window_blocked with no compaction ever running: the pre-send check compacted at 85% of the window while the API preflight rejects at roughly 65% (history + system + tools + max_tokens). The ACP pre-send check now budgets the way the preflight does, auto-compaction triggers on the latest response's actual context size (works with prompt caching), run_turn compacts and resends once on a context-window rejection and drops the unanswered prompt if it still fails, and compact_in_place rewrites the persisted transcript so a resume no longer reloads pre-compaction history. Context-window errors are now classified as history_context_too_large vs single_request_too_large.
• Keep tool role in compaction messages so tool_results stay paired (#546) — LLM compaction silently fell back to the lossy local summary whenever the summarised conversation contained a parallel tool call, because build_compaction_messages remapped Tool messages to User and broke the tool_use / tool_result pairing Anthropic requires. Only System -> User is remapped now. CompactionResult carries a summary_source, and the /compact report prints a Summary line (llm, local, or local (LLM compaction failed: ...)) so any degradation is visible.
• PTY test deflake (#544) — iocraft_repl_ctrlc_hint settles before sending Ctrl-C.
