Good + cleanup, zero protocol cost. + +Goal command progress: + +10. Started `/goal` implementation from the current `feat/goal` branch, which was still at + `main` with no committed goal work. Chosen architecture: keep the goal state in the + ACP backend because it already owns the long-lived ACP session, and have the TUI send + typed goal ops instead of forwarding `/goal` text to arbitrary agents. +11. Added the first shared protocol contract for thread goals: statuses, typed get/set/clear + ops, and objective validation. Token budgets remain intentionally out of scope for the + first Nori implementation, matching the goal-context instruction. +12. Added normalized ACP-client events for goal updated/cleared notifications in + `nori-protocol`. This keeps the ACP backend as the goal-state owner while giving the + TUI an agent-independent event shape to render. +13. Added an in-memory ACP-session goal state machine and wired `ThreadGoalGet`, + `ThreadGoalSet`, and `ThreadGoalClear` through `AcpBackend::submit`. Goal time is + accumulated only while the status is active; paused/blocked/limited/complete states do + not accrue elapsed time until resumed. +14. Wired the TUI `/goal` command to typed ACP goal ops. Bare `/goal` requests the current + goal, `/goal ` creates/replaces the objective as active, `/goal pause`, + `/goal resume`, and `/goal clear` map to direct mutations, and `/goal edit` preloads + the current objective into the composer when the TUI has a goal snapshot. +15. Preserved goal update/clear client events through transcript replay conversion. This + restores the latest TUI-visible goal snapshot on resumed sessions, but the ACP backend + still needs a stronger state rehydration path before automatic continuation can rely on + a replayed goal without a fresh mutation. +16. Rehydrated ACP backend goal state from replayed goal events during resume setup. Active + goals resume elapsed-time accounting from their last `updated_at` timestamp; a later + replayed clear removes the backend goal state. +17. Added ACP prompt-context injection for active session goals. Before user input is sent to + the ACP agent, the backend now prepends a structured `` block with the goal + status, objective, elapsed active time, and token count, while preserving compact-summary + ordering when a summary is pending. +18. Added goal token accounting from ACP usage updates. The backend keeps a usage baseline + when a goal is created, updates goal token totals as `UsageUpdate` client events arrive, + emits refreshed goal snapshots, and rebuilds the baseline from replayed usage/goal events + when resuming a session. +19. Compared the current ACP goal implementation against upstream Codex goal behavior after + verification. Remaining parity gaps are intentional blockers for the next design slice: + Codex confirms before replacing an unfinished goal, prompts on resume for paused/blocked + goals, exposes model-facing `create_goal`/`update_goal` tools, and can automatically + continue active goals when the runtime goes idle. The current Nori slice stores, + rehydrates, renders, and injects goal context, but does not yet auto-submit continuation + turns or expose structured goal tools to ACP agents. +20. Added the first ACP-native automatic continuation slice. After a visible user prompt + completes with an active goal and the ACP runtime is idle with no queued user work, the + backend now submits one hidden `GoalContinuation` prompt to the same ACP session. The + hidden prompt is omitted from visible queue text and user transcript entries, while the + agent response still renders and records like normal assistant work. This intentionally + does not recurse after continuation turns; deeper Codex-style autonomous loops and + structured agent goal tools remain follow-on parity work from note 19. +21. Matched another Codex `/goal` UX affordance in the Nori TUI: submitting a new objective + while an unfinished goal is cached now opens a replacement confirmation picker instead + of immediately overwriting the active thread goal. Completed goals remain terminal and + can be replaced directly without confirmation. +22. Fixed a stale pending-edit edge case in `/goal edit`. When the TUI requests a backend goal + snapshot for editing and the backend replies that no goal exists, the pending edit request + is now cleared, so a later unrelated `ThreadGoalUpdated` event does not unexpectedly + replace the user's composer contents with `/goal `. +23. Added resume notices for replayed paused, blocked, and usage-limited goals. After ACP resume sends deferred + replay events, the backend now appends a non-persisted session info notice when the restored + goal is stopped but resumable, pointing the user at `/goal resume`, `/goal edit`, and `/goal + clear` without recording duplicate resume-only messages into future transcripts. +24. Added backend-owned goal MCP tools for ACP agents that advertise HTTP MCP support. Nori now + registers an in-process `nori-goal` MCP server over ACP MCP-over-ACP during new, resumed, and + compaction-created sessions; agents can call `get_goal`, `create_goal`, and `update_goal` + while the backend remains the goal-state authority and continues emitting transcript-backed + `ThreadGoalUpdated` snapshots. Agents without HTTP MCP support still receive the existing + prompt goal context and hidden continuation behavior without the structured tools. +25. Addressed review feedback on the goal MCP slice. Server-side ACP resume now rebuilds goal + state from transcript-owned goal replay plus any agent load replay so non-goal ACP + notifications cannot erase a restored goal. The local MCP bridge now has direct + `_mcp/connect`/`_mcp/message` routing coverage and retains dynamic handler registrations only + for the current advertised local MCP endpoint instead of leaking stale endpoints indefinitely. +26. Added the deeper autonomous continuation slice for ACP agents that can use goal tools. When + an agent advertises HTTP MCP support, hidden `GoalContinuation` turns can now chain after + prior continuation turns while the active goal remains open and the runtime is idle; agents + without HTTP MCP support keep the previous single hidden continuation after a visible user + turn so unsupported agents are not put into an unbounded loop they cannot stop. +27. Follow-up: disable or clearly mark `/goal` unavailable when the active ACP agent does not + support HTTP MCP servers. The current slash popup has description overrides but no disabled + row state, and pasted `/goal ...` is handled separately in `chatwidget/goal.rs`, so the + correct small fix is probably both UI affordance and a backend/TUI command guard. This + matters because prompt goal context can still work without MCP, but the main close-the-loop + path depends on the agent having the `nori-goal` MCP tools so it can mark goals complete or + blocked. +28. Fixed the quick goal visual/accounting issues from bugs 3, 4, and the scoped version of 5. + The TUI now suppresses history cells for accounting-only `ThreadGoalUpdated` refreshes while + still rendering explicit `/goal` status requests and objective/status changes. Goal summaries + use compact SI token formatting and label the count as excluding subagents. Backend goal token + usage now accumulates positive ACP usage deltas across context-window drops instead of + mirroring the latest session usage value. +29. Verified the bug 3/4/5 slice end-to-end and pushed it to PR #491 as commit `846c27c1`. + Local verification covered `cargo test -p nori-acp`, `cargo test -p nori-tui`, + `cargo build --bin nori && cargo test -p tui-pty-e2e`, `just fmt`, scoped `just fix`, + snapshot acceptance, and an isolated ElizACP TUI smoke test. GitHub checks for the PR passed + afterward: `Linux checks` and `cargo-deny`. + +Follow-up bug investigations - 2026-05-28: + +### Bug 1: `nori-goal` MCP startup failure + +- Finding: The existing `nori-rs/closing-loop/nori-goal-mcp-over-acp-bug-report.md` + report is substantially correct. Nori advertises backend-owned goal tools as an + ACP local MCP server by sending an HTTP MCP server entry whose URL is `acp:`. + Codex ACP treats that entry as a normal streamable HTTP MCP server and Codex's + HTTP client rejects the `acp:` scheme before Nori's `_mcp/connect` bridge can run. +- Evidence: Goal MCP registration is guarded only by `mcp_capabilities.http` in + `nori-rs/acp/src/backend/thread_goal_mcp.rs`; registration appends + `McpServer::Http { url: "acp:" }` in + `nori-rs/acp/src/connection/sacp_connection.rs`; the intended local receiver is + `_mcp/connect` in `nori-rs/acp/src/connection/local_mcp.rs`. +- Correction to the prior report: the built-in Nori Codex agent still launches + `@zed-industries/codex-acp`, not `@agentclientprotocol/codex-acp`. Both appear to + have the same shape mismatch: they advertise HTTP MCP but forward/load the + `acp:` URL as a normal HTTP MCP config instead of using ACP `_mcp/connect`. +- Quickest estimate: 2-4 hours for a focused mitigation that disables local goal + MCP advertisement for Codex ACP and gates continuation chaining on goal MCP + being actually supported/registered, not raw HTTP MCP capability. A real + loopback HTTP MCP server is a more complete but larger 1-2 day fix. Upstream + Codex ACP support for ACP-local MCP is the cleanest architecture, but timing is + outside this repo. +- Risks/unknowns: Need confirm which non-Codex ACP agents actually support `acp:` + local MCP before changing behavior broadly. A Codex-specific deny path is safer + than treating all HTTP MCP agents as broken. + +### Bug 2: New `/goal ` does not begin work immediately + +- Finding: Confirmed. `/goal ` is a state mutation only. The TUI + intercepts the slash command, sends `Op::ThreadGoalSet`, and returns before any + normal ACP `session/prompt` is submitted. +- Root cause: Automatic hidden goal continuation is currently triggered only after + a completed visible user turn or prior continuation turn. Setting the goal does + not enqueue a hidden `GoalContinuation` prompt, so work starts only after the + user submits a second prompt. +- Evidence: `/goal` sends only `ThreadGoalSet` from + `nori-rs/tui/src/chatwidget/goal.rs`; `handle_thread_goal_set` stores state and + emits `ThreadGoalUpdated`; `maybe_submit_goal_continuation` is called from + completed-turn handling in `nori-rs/acp/src/backend/session_runtime_driver.rs`. +- Quickest estimate: small, 1-2 hours with tests. More like 2-3 hours if the same + change covers `/goal resume`, active-goal replacement while a request is in + flight, and HTTP-MCP chain semantics. +- Likely fix: after a successful active `ThreadGoalSet`, enqueue the existing + hidden `GoalContinuation` prompt when the runtime is idle and there is no queued + user work. Extract the enqueue portion of `maybe_submit_goal_continuation` so it + can be reused without requiring a `CompletedTurn`. + +### Bug 3: Goal status prints constantly into history + +- Finding: Confirmed. Nori emits a `ThreadGoalUpdated` event for every ACP usage + update, and the TUI renders every `ThreadGoalUpdated` as a full history summary. + That makes token/time refreshes look like repeated goal status messages. +- What Codex does: upstream Codex stores goal state and updates a compact footer + status indicator such as `Pursuing goal (...)`. It does not append every backend + goal update into chat history. History/info messages are mostly tied to explicit + `/goal` actions such as set, status, pause, resume, or clear. +- Evidence: ACP usage updates are converted into `ThreadGoalUpdated` in + `nori-rs/acp/src/backend/thread_goal.rs`; the TUI always calls + `show_goal_summary` from `handle_thread_goal_updated` in + `nori-rs/tui/src/chatwidget/goal.rs`. Codex's footer/status indicator path is in + `other-repos/codex/codex-rs/tui/src/chatwidget/goal_status.rs` and + `other-repos/codex/codex-rs/tui/src/bottom_pane/footer.rs`. +- Quickest estimate: small, 1-2 hours with focused TUI tests/snapshot updates. + Matching the upstream footer/status model more fully is closer to 0.5-1 day. +- Likely fix: keep updating cached `current_goal` on every event, but only append + a history summary when user-visible goal meaning changes or when the user + explicitly asks for `/goal` status. Minimal safe heuristic: suppress summaries + when previous and new goal have the same objective/status/created timestamp and + only accounting fields changed. +- Risks/unknowns: The protocol currently does not carry provenance that says + "this update is an explicit user-requested status response" versus "this update + is backend sync." Without adding provenance, the first fix will be heuristic. + +### Bug 4: `Tokens used` should pretty print + +- Finding: Display-only bug. `nori-rs/tui/src/chatwidget/goal.rs` renders + `Tokens used` with `goal.tokens_used.to_string()`. +- Existing helper: `codex_protocol::num_format::format_si_suffix` already exists + and is used elsewhere for compact token counts, so the cheapest fix does not + need a new formatter or dependency. +- Format ambiguity: `195043 -> 195K` matches the existing Nori helper and upstream + Codex compact formatting. The example `32492004 -> 32,492M` is ambiguous because + it reads as 32,492 million, while existing Nori/upstream compact formatting + would be around `32.5M`. +- Quickest estimate: tiny, 15-30 minutes including one TUI snapshot update. +- Likely fix: replace raw `to_string()` with `format_si_suffix(goal.tokens_used)`, + update the existing goal summary snapshot to cover a nonzero count, and decide + whether `32.5M` is acceptable or whether this needs a new project-specific + convention. + +### Bug 5: Goal token count mirrors latest usage instead of cumulative capacity + +- Finding: Confirmed. Goal token accounting treats ACP `UsageUpdate.used` as if it + were cumulative goal spend, but ACP usage is "tokens currently in context". Nori + subtracts a single baseline from a point-in-time context-window measurement. +- Evidence: `StoredThreadGoal` stores `tokens_used`, `token_usage_baseline`, and + `last_session_used_tokens`. On each usage update, + `nori-rs/acp/src/backend/thread_goal.rs` sets `goal.tokens_used = + used_tokens.saturating_sub(baseline)`. That exactly explains why the goal count + mirrors usage updates and can reset or drift across compaction, resume, subagent + sidechains, and new ACP session IDs. +- Likely correct model: keep goal-owned cumulative usage and per-source/segment + last-seen context values. For a same segment, add only positive deltas; when + context usage drops because of compaction/resume/session changes, start a new + segment instead of subtracting from an old baseline. Provider transcript totals + may be needed to include subagent usage accurately, with deduping by transcript + message/session identity. +- Quickest estimate: medium, 1-2 days for a focused segment-based approximation + with tests. More if robust provider transcript aggregation across Claude, Codex, + Gemini, and sidechain/subagent messages is required. +- Risks/unknowns: ACP does not appear to expose cumulative token spend directly. + Provider transcript schemas differ and may be stale during live sessions. Replay + and live `session/load` usage must be deduped to avoid double-counting. + +### Bug 6: Agent repeats "Verified again..." and cannot stop the goal loop + +- Finding: High-confidence root cause is continuation chaining based on advertised + HTTP MCP capability rather than observed working `nori-goal` MCP tools. For + Codex ACP, the tools fail to start because of Bug 1, but Nori still believes the + agent can stop itself via goal MCP and therefore keeps chaining hidden + continuations while the backend goal remains active. +- Evidence: `maybe_submit_goal_continuation` chains after a `GoalContinuation` + when `connection.capabilities().mcp_capabilities.http` is true. The actual stop + path requires the agent to call MCP `update_goal({"status":"complete"})` in + `nori-rs/acp/src/backend/thread_goal_mcp.rs`. Since Codex never successfully + initializes the `acp:` goal MCP server, the active goal never transitions to + complete through that path. +- Why those history cells appear: hidden `GoalContinuation` prompts are not shown + as user prompts, but assistant output is still recorded and finalized like normal + assistant history. The repeated "Verified again..." messages are normal + assistant completions from each chained hidden continuation, not duplicate TUI + rendering of the same cell. +- Quickest estimate: small for mitigation, roughly 1-2 hours to disable chained + continuation unless goal MCP is known usable. Medium, 0.5-1 day, to track an + observed `_mcp/connect` success from the local MCP bridge and gate chaining on + that runtime state. +- Likely fix: allow one post-user hidden continuation as the unsupported-agent + fallback, but do not allow `GoalContinuation -> GoalContinuation` chaining until + Nori has observed a working `nori-goal` MCP connection. A faster temporary + mitigation is to disable chained continuations entirely. diff --git a/goal-command-architecture-diagrams.md b/goal-command-architecture-diagrams.md new file mode 100644 index 000000000..d1c1b77ba --- /dev/null +++ b/goal-command-architecture-diagrams.md @@ -0,0 +1,276 @@ +# Goal Command Architecture Diagrams + +This note compares two implementations of the same user-facing idea: a long-lived +thread goal that keeps the agent aligned across turns until the model marks the +goal complete or blocked. + +- In the raw Codex harness, goals are native session/runtime state. +- In Nori CLI over ACP, goals are owned by the Nori ACP backend and projected + into an external ACP agent through prompt context plus a local `nori-goal` + MCP server. + +## Raw Codex Harness + +Codex keeps the goal loop inside the core harness.

ACP usage updates add only positive deltas since the last checkpoint to goal-local `tokens_used`; if context-window usage drops after compaction or session reset, the already accumulated goal usage is preserved and the lower value becomes the next checkpoint. Only the `Active` status accrues active time; paused, blocked, usage-limited, budget-limited, and complete goals keep their accumulated time until they become active again. Objective validation is shared with `@/nori-rs/protocol/src/protocol/mod.rs` so the TUI and backend enforce the same acceptance rules, and goal status text uses the shared compact elapsed-time and SI-token formatters from `@/nori-rs/protocol/src/num_format.rs`. + +`thread_goal_mcp.rs` is a bridge, not a second store. Its tools lock the same `ThreadGoalState` used by TUI `/goal` operations, return JSON snapshots shaped for model consumption, and emit the same `ThreadGoalUpdated` client event after mutations. The bridge records those emitted events through `@/nori-rs/acp/src/backend/transcript.rs` when a transcript recorder is available; session setup stores the recorder behind a shared cell because the goal MCP bridge can be created before all resume/create paths know the final transcript session id. + +The local `nori-goal` server is only advertised when `@/nori-rs/acp/src/backend/thread_goal_mcp.rs` sees HTTP MCP support from `@/nori-rs/acp/src/connection/mod.rs`. Nori advertises a real `http://127.0.0.1:/mcp` endpoint rather than an ACP pseudo-URL, because Codex ACP and Claude ACP both forward ACP `mcpServers` to their underlying clients as ordinary HTTP MCP server config. The loopback server is owned by the ACP backend and talks directly to the same in-memory goal state as `/goal`. + +The model-facing MCP contract is intentionally narrower than the user-facing `/goal` command surface. `create_goal` creates a new active goal only when no goal exists, rejects token budgets for now, and delegates objective validation to `ThreadGoalState`. `update_goal` only lets an agent mark the existing goal `complete` or `blocked`; pause, resume, usage-limited, and budget-limited transitions remain controlled by the user or the backend system path. Errors are returned as MCP tool errors instead of changing state. + +Before user prompts are submitted to the ACP runtime, `user_input.rs` prepends the current goal as a structured `` block when a goal exists. Hook context is still applied before goal context, and compact summaries remain the outermost framing instruction, so resumed/compacted turns retain their existing prompt-ordering invariant while still carrying goal state to the agent. The prompt goal context and hidden continuation prompt use the same compact elapsed-time and token-count formatting as the visible TUI goal summary. + +Agents that are not advertised the local `nori-goal` server still receive goal context through prompt transformation, an immediate hidden goal-continuation prompt when an active goal is set while the runtime is idle, and a single hidden goal-continuation prompt after visible user turns. The local MCP server is additive for capable agents so they can use structured goal tools; it is never required for goal context, transcript replay, usage accounting, or one-shot continuation behavior. + +After an active goal mutation or a visible user prompt completes with `StopReason::EndTurn`, `session_runtime_driver.rs` may submit a hidden goal-continuation prompt to the same ACP session. `thread_goal.rs` owns the continuation prompt text so it is derived from the current backend goal snapshot, not from TUI state or transcript text. The driver only starts a continuation when the goal is active, the reducer has returned to idle, and no queued user work remains. Chaining from one hidden `GoalContinuation` into another is gated on `goal_mcp_connected`, an `@/nori-rs/acp/src/backend/mod.rs` session flag that `thread_goal_mcp.rs` flips only after the local HTTP MCP server receives an `initialize` request. Agents without a connected goal MCP endpoint receive at most one hidden continuation per active goal mutation or visible user turn. + +Goal state is also part of the replay contract. `transcript.rs` passes Nori-owned goal update and clear events through replay, and `session.rs` seeds `ThreadGoalState` from those transcript-derived events before ACP session setup advertises local MCP tools. Server-side `session/load` can also emit ACP replay notifications while loading; those normalized client events are deferred until backend setup completes, then combined with the transcript replay events before rebuilding `ThreadGoalState`. This ordering matters because ACP agents replay their own session history, but they do not replay Nori-owned `ThreadGoalUpdated` events, so the transcript remains authoritative for goal state even when the agent emits load replay notifications. + +When a resumed goal is paused, blocked, or usage-limited, `thread_goal.rs` derives a one-time `SessionUpdateInfo` notice from the rehydrated snapshot so the TUI can show why goal automation will not continue until the user resumes, edits, clears, or resolves the blocker. That notice is emitted directly by `session.rs` after deferred replay events and is not written back into the transcript, so each future resume still derives its notice from goal state instead of accumulating duplicate history entries. ACP usage updates still normalize to `SessionUpdateInfo`, but `session_runtime_driver.rs` observes those events and asks the goal state to refresh `tokens_used`; when a goal exists, the backend emits a follow-up `ThreadGoalUpdated` snapshot so the TUI and transcript stay synchronized with usage accounting. + **Custom Agent TOML Schema** (`config/types/mod.rs`): Custom agents are defined under `[[agents]]` in `config.toml`.

Choosing "Replace current goal" forwards `AppEvent::CodexOp(Op::ThreadGoalSet)` with the replacement objective and `Active` status; choosing "Keep current goal" dismisses the popup without changing backend state. Completed goals are replaced directly because they no longer protect an in-progress objective. This mirrors the Codex goal replacement flow while preserving the invariant that only explicit user confirmation can overwrite an unfinished goal snapshot cached from `ClientEvent::ThreadGoalUpdated`; the ACP backend owns the follow-up behavior that starts active goal work immediately when it can. + The transcript pager overlay uses each history cell's transcript view rather than the live summary view. To keep reopened transcripts readable, the overlay caps non-patch cells at 20 lines and appends an omission marker, while patch cells keep their full diff output for review. In ACP sessions, `ClientToolCell` provides differentiated `transcript_lines()` for Execute tools (shell-style `$ command` format via `render_execute_transcript_lines()`) while exploring and edit cells reuse their `display_lines()` rendering for transcripts. **Approval Request Routing** (`chatwidget/event_handlers.rs`, `bottom_pane/approval_overlay.rs`): ACP approval requests arrive as `ClientEvent::ApprovalRequest` containing a `nori_protocol::ToolSnapshot`. The `approval_request_from_client_event()` function performs two-way routing: Execute tools with `Invocation::Command` map to `ApprovalRequest::Exec` (bash-highlighted overlay), and everything else (including Edit/Delete/Move) maps to `ApprovalRequest::AcpTool`. The `AcpTool` variant carries a boxed `ToolSnapshot`, a `cwd: PathBuf` (threaded from `self.config.cwd` in the chat widget), and dispatches decisions via `Op::ExecApproval`, which gives users the "always approve" option that `ApplyPatch` did not have. The `From` impl in `approval_overlay.rs` applies `relativize_paths_in_text` to the title before building the overlay prompt and `DiffSummary`, so users see relative paths instead of absolute ones. The fullscreen approval preview in `app/event_handling.rs` also uses the real `cwd` from the request for `DiffSummary` construction. `ApprovalRequest::ApplyPatch` is now only used by the legacy non-ACP codex backend. History cells for AcpTool decisions are produced by `history_cell::new_acp_approval_decision_cell()`, using `format_tool_kind()` for the kind label. diff --git a/nori-rs/tui/src/bottom_pane/chat_composer/tests/part6.rs b/nori-rs/tui/src/bottom_pane/chat_composer/tests/part6.rs index 4310739a7..4c1fa8084 100644 --- a/nori-rs/tui/src/bottom_pane/chat_composer/tests/part6.rs +++ b/nori-rs/tui/src/bottom_pane/chat_composer/tests/part6.rs @@ -544,6 +544,32 @@ fn slash_mode_prompt_stays_active_after_command_arguments() { );
