Project memory lives at +`.nooa/memory/memory.sqlite` by default; session memory lives beside the +session database.

See +[`docs/themes.md`](docs/themes.md) for the schema, semantic color roles, and +validation rules. + +### MCP servers + +Use the TUI commands for the common lifecycle: + +```text +/mcp list +/mcp add docs https://docs.example.com/mcp +/mcp approve docs +/mcp approve docs +/mcp connect docs +/mcp disconnect docs +/mcp remove docs +``` + +`/mcp add` writes an HTTP URL or a single stdio command to the project +`.nooa/settings.yaml`. Configuration is discovery, not trust: the TUI shows a +secret-safe fingerprint review and requires the user to repeat its confirmation +code before any transport or local process starts. Any configuration change +invalidates that approval. Environment placeholders are resolved only after +approval. `/mcp remove` removes inline project servers and revokes their stored +approvals without disturbing sibling settings. Servers sourced from an external +`.mcp.json` must be removed from that file. + +For a richer server definition—stdio arguments, environment mappings, headers, +or OAuth settings—use `/mcp-add `. That user-invocable +skill asks the coding agent to edit the same project settings without embedding +secret values, then directs you back through the user-owned review and approval +flow. Removal is always `/mcp remove ` (or an edit to the source +`.mcp.json` for externally defined servers). + +For stdio arguments, environment variables, headers, or OAuth options, use the +full settings form: + +```yaml +tui: + mcp_servers: + local-tools: + command: uvx + args: [my-mcp-server] + env: + LOG_LEVEL: info + hosted-tools: + url: https://tools.example.com/mcp + transport: streamable-http + oauth_client_id: my-client-id + oauth_scope: "tools.read tools.write" +``` + +Keep secret values in the host environment and use literal `${VAR}` placeholders +in repository config. First-time OAuth consent remains a human browser step; +manual codes are collected in a masked in-app prompt. Cached credentials are +reused by later `/mcp connect` calls after the exact server definition remains +approved. + See the main repo [README](https://github.com/NVIDIA-NeMo/labs-OO-Agents/blob/main/README.md) for the framework documentation. ## Interactive coding sessions diff --git a/packages/nooa-cli/docs/themes.md b/packages/nooa-cli/docs/themes.md new file mode 100644 index 000000000..0dab6e245 --- /dev/null +++ b/packages/nooa-cli/docs/themes.md @@ -0,0 +1,100 @@ +# TUI themes + +NOOA ships four themes: `mocha`, `latte`, `vsdark`, and `vslight`. + +Use `/theme` or `/theme picker` to open the installed-theme browser.

ANSI received from an agent, model, tool, +subprocess, or exception is untrusted. In fullscreen it is parsed into styled text +with an allow-list of SGR attributes and safe hyperlink metadata; OSC clipboard/title +commands, DCS/APC, C0/C1 controls, cursor/erase commands, and malformed or incomplete +escapes are rendered visibly or discarded, never emitted as terminal control bytes. + +## Current ownership map + +| Responsibility | Owner and important seams | +| --- | --- | +| PTK layout, focus, key bindings, subviews | `TUIApplication` renderer shell | +| Transcript ordering and presentation | one ordered consumer feeding either the native sink or `FullscreenTranscriptModel` | +| Agent state and direct controls | structural `InteractiveAgent` interface | +| Local dispatch, callbacks, and worker lifecycle | `LocalAgentRunner`, outside renderer classes | +| Observation replacement and stale-callback rejection | `AgentController` | +| Session/storage/command integration | `Session` composition root plus narrow `TUIHostServices` | + +`Session` coordinates concrete-agent storage, event-manager, shell, and command +integration. Concrete queue and callback details are isolated in `LocalAgentRunner`. +The renderer receives an `InteractiveAgent`; it does not receive concrete queues, +storage backends, shell objects, event managers, or transport protocol objects. + +## Python-native boundary + +The host-neutral interface lives in `nooa_cli.interactive` and uses structural typing: + +```python +class InteractiveAgent(Protocol): + @property + def state(self) -> AgentState: ... + def observe(self, callback, scheduler, on_terminated=None) -> Observation: ... + def submit(self, text: str) -> bool: ... + def interrupt(self) -> bool: ... + def withdraw_pending_input(self) -> str | None: ... + def stop(self) -> bool: ... +``` + +The boundary is ordinary Python, not a transport model. There are no public action +unions, receipts, capability strings, event envelopes, sequence numbers, reconnect +states, or replay handshakes. A future subprocess or remote implementation may be a +proxy with the same Python surface, but transport concerns stay private to that proxy. +`nooa_acp` remains an edge adapter and is not the native TUI contract. + +`AgentState` and every nested value are immutable. The UI reads complete snapshots +rather than reducing a public event stream. A successful direct command means that the +operation was admitted, not completed; its state effect is visible through `state` +before the method returns. `stop()` requests owned lifecycle shutdown, while closing an +`Observation` only stops that frontend from observing. + +## Observation and switching invariants + +* `observe()` atomically registers against the latest state and schedules an initial + delivery after releasing the agent state lock. +* Each observation retains only its latest pending state. Publications coalesce into at + most one scheduled or running drain, callbacks are serialized, and an older snapshot + cannot overwrite a newer one. +* A scheduler may execute inline or raise. Scheduler/listener failure closes only that + observation, records `Observation.failure`, and invokes `on_terminated` exactly once. + The controller enters a visible disconnected state and gates commands rather than + continuing against a frozen snapshot. Agent locks are never held while invoking + scheduler or listener code. +* `Observation.close()` is idempotent. It prevents queued callbacks from starting; + a callback already running may finish. It never stops the agent. +* `AgentController` installs replacement observation and captured state transactionally. + Setup failure leaves the old agent active. On success it publishes the new generation, + closes the old observation, and rejects every late old-generation callback. A reserved + transition rejects callback-issued commands without holding a routing lock while it + waits for callback completion; observation cleanup failure cannot poison controller + bookkeeping or later close/replace operations. +* Agent switching does not reconstruct the renderer or stop the previous agent merely + because it is no longer observed. The composition root owns resources it creates and + closes them exactly once. +* UI mutation is marshalled onto the prompt_toolkit owner loop. Background producers do + not mutate renderer state directly. + +## Fullscreen transcript and viewport invariants + +The transcript model stores safe immutable presentation records with stable IDs. It +supports append, streaming replacement/finalization, clear/tag removal, and bounded +retention. Live fullscreen retention is capped at 10,000 records or a conservative +16 MiB resident-text budget, whichever is reached first; durable event history remains +a separate authority. The byte budget charges source, rendered replay expansion, model +ANSI/plain copies, and the model's bounded projection/format caches. Source blocks and +model records are evicted together, including after resize replay changes their size. +Projection wraps records for the current cell width and caches only derived data. + +At the tail, append and resize continue following the tail. While scrolled up, the +viewport preserves a logical record ID plus visual-line offset across append and +geometry changes. Prefix eviction also adjusts record-local selection offsets when it +removes a synthetic joining separator, so wholly retained selections keep their exact +payload. Eviction and clear have deterministic fallback anchors. + +Unicode width uses terminal cells and grapheme clusters, including CJK, emoji, and +combining marks. Source and export text always preserve valid Unicode. If a grapheme is +physically wider than a one-cell viewport, only the screen projection uses a narrow +ellipsis; emitting the original wide glyph would desynchronize the terminal cursor from +prompt_toolkit's screen model. Tiny terminals keep the composer usable without +prompt_toolkit's `Window too small` replacement becoming the UI. + +Fullscreen width observations do not replay static records: the transcript model already +projects those records for the requested width. Width-sensitive semantic callbacks are +coalesced until resize activity settles and cache their latest width result. This keeps +the ordinary 10,000-record resize callback constant-time while retaining exact semantic +rerendering for Rich output that genuinely depends on width. + +## Validation and rollout + +Unit tests cover immutable state, observation scheduling/coalescing/failure/close races, +controller replacement and stale-callback filtering, direct command routing, local +lifecycle races, transcript projection, and terminal safety. Component tests inspect +prompt_toolkit screen cells. A composition test exercises `Session.run()` through the +real local runner, direct agent observation, renderer, and first submit/output cycle. +Fault-injection tests prove that independent teardown failures cannot skip later cleanup, +that the primary application exception wins, and that terminal restoration still runs. +A POSIX PTY test verifies alternate-screen entry and restoration on normal exit. + +EOF, interrupt, startup-failure PTY cases and tmux/SSH resize soak tests remain rollout +work. Explicit native modes retain characterization coverage while fullscreen is the +resolved default. + +## Explicit non-goals + +This project does not provide remote transport, authentication, durable event replay, +multi-client arbitration, generalized arbitrary-call RPC, an ACP-driven native API, a +Rust frontend, or a Textual rewrite.
