rob thijssen	cbadfcf112	feat(helexa-acp): plan mode — third session mode for read-and-plan-only flows ... Plan mode is the most restrictive of the three session modes: bash is disabled outright, writes are confined to a per-project plan directory under $XDG_DATA_HOME/helexa-acp/plans/<basename>-<8hex>/, and reads / list_dir are unrestricted. The system prompt is rebuilt at the top of every round so a mid-turn switch into (or out of) plan mode takes effect on the next streaming round, and plan mode appends a 3-option menu instructing the model to stop and let the user pick how to proceed once the plan is complete. The project id is basename + FNV-1a-32 of the cwd so it stays stable across runs (SipHash's DefaultHasher reseeds per process), while still disambiguating multiple checkouts that share a final path component.

rob thijssen	5aac1ffc59	feat(helexa-acp): session resume via session/load ... Zed restarts (frequent during helexa-acp dogfooding) used to lose every conversation because we'd ignore the load_session capability and treat every project-reopen as a fresh session/new. Persist sessions to disk and honour session/load so the agent panel comes back where it left off. Storage layout: $XDG_DATA_HOME/helexa-acp/sessions/{session_id}.json Each file holds session_id, cwd, model_id, mode_id, full Message history, plus created/updated timestamps. Atomic save via tempfile+rename so a crash mid-write can't corrupt the store. Touch points: - src/store.rs (new) — sessions_dir() resolution, save/load via default and explicit-dir entry points (so unit tests don't have to race on XDG_DATA_HOME). 5 unit tests cover round-trip, not-found errors, atomic overwrite, tool-call/result preservation, and the filename sanitiser's path-traversal handling. - src/provider/mod.rs — Serialize/Deserialize on Role, Message, MessageContent, ToolCall. MessageContent::Text turned into a struct variant ({text: ...}) so internally-tagged JSON works. - src/agent.rs — initialize_response advertises load_session: true; handle_load_session reads the file, snapshots in-memory state, returns LoadSessionResponse with the persisted mode preselected; drive_prompt persists at the end of every prompt round under the session lock with the I/O outside the lock.

rob thijssen	0609f1ac5d	feat(helexa-acp): add tools, session modes, and permission gating ... Stage 3 introduces five tools (read_file, write_file, edit_file, list_dir, bash) backed by ACP fs/* and terminal/* calls, a ClientOps trait so the runner is mock-testable, two session modes (default + bypassPermissions) with session/set_mode honouring them, and a tool-call loop in the agent that streams the model, dispatches each call, feeds results back into history, and re-enters until the model finishes or MAX_TOOL_ROUNDS is hit.

rob thijssen	96fc379893	feat(helexa-acp): wire ACP agent loop for text-only conversations ... Stage 2 lands the agent loop on top of the Stage 1 scaffold: session state with per-session cancellation, a system-prompt builder honouring HELEXA_ACP_SYSTEM_PROMPT_PATH / system_prompt_path TOML, and handlers for initialize / session/new / session/prompt / session/cancel that stream provider output back as session/update notifications. Verified end-to-end against cortex from Zed. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>	2026-05-28 09:46:22 +03:00
