 `reasoning.py`: thinking strength as `reasoning_effort` (`ReasoningEffortConfig`: `""` = send nothing | `none` … `high` … `max`) and `thinking_budget_tokens`, settable on `[agent]`, a provider, or a model entry — `resolve_reasoning(agent, provider, model)` merges the layers per field (model > provider > agent) and clamps `max` (DeepSeek chat only) to `xhigh` for every other surface, returning a `ReasoningConfig` the agent loop and `create_client` consume.

 ### Tools (`tools/`)
 
@@ -120,7 +120,7 @@ Click app + readline REPL. Entry: `plyngent` / `python -m plyngent`.
 - Slash: Click group in `cli/slash.py` + `awaitlet` for async work; Tab completer from registry + ParamType `shell_complete`. `/history` is turn-oriented (`cli/transcript.py`): a turn runs from a user row to the next one, rows carry **display ordinals** (never DB row numbers; restart with the session), the turn's ends (user + final answer) always print in full, `-v` expands every row (one-liners), `-vv` prints full bodies + local rows, `--preview` collapses every row, and `N`/`last [N]` address turns while `--message N` addresses one row. Multiline `"""` … `"""`; `/edit` via `$VISUAL`/`$EDITOR` (blocking only). `/yolo on|off|once` for soft destructive confirms. `/model --persist` / `/models --persist` write model catalog entries into TOML. `/todos` for human show/push/pop/clear of the todo stack. `/skills` (`list` default) prints the discovered skills with their roots, shadowed copies, and frontmatter notes; `/skills search PATTERN` runs the matching tool handler (the slash path binds the tool context itself); `/skills open NAME` reveals the skill's directory in the system file manager. `/mcp` (`list` default) prints per-server status/tool counts + an `instructions` preview when the server sent usage guidance, + last stderr lines; `/mcp reconnect` re-reads config, restarts every enabled server, and rebuilds the tool registry. `/grants` lists directory-access grants (`revoke <index|all>`; config grants point at the TOML); `/status` includes the grant count and the visible skill count (or `off` when `[skills].enabled` is false).
 - `/btw` side questions: forked session; main transcript/DB untouched. `--tools=read` (default) exposes only `READ_ONLY` tools under `read_only_context()` (fetch=GET) with the main session view; `--tools=no` off; `--tools=full` whole-registry clone with fresh session. Tools off: default falls back to no tools; explicit `read`/`full` errors. The model gets an `aside` notice as its last message before the question (unsaved exchange + tool scope), shown to the user as `[notice] aside: …`.
 - Explicit `/resume` or `--session` from another workspace prompts: **keep** / **update** / **abort**. A session resumed by a **freshly started process** (`--session` / default latest) also gets a `resume` notice about what a restart drops (PTY sessions, running commands, temp workspaces) — resuming inside a live process pushes nothing.
-- Host notices (`agent/notices.py`): system-level messages appended as trailing `developer` rows, never system-prompt edits — `Notice.to_message()` for the model, `.summary` for the user via `cli.display.echo_notice` (`--quiet` hides the user line only). Durable hosts persist them (`ChatAgent.push_notice`); a side agent without memory keeps its notice local. Trailing developer messages never end a turn, so `/retry` still sees an interrupted turn behind a notice or checkpoint.

Durable hosts persist them (`ChatAgent.push_notice`); a side agent without memory keeps its notice local. `has_notice()` dedupes a session-scoped notice: the `skills` one is pushed once per session (feature enabled + tools on), lists nothing, and makes the model ask with `skill_list` / `skill_search`. Trailing developer messages never end a turn, so `/retry` still sees an interrupted turn behind a notice or checkpoint.
 - Failed/cancelled turns: user kept; **committed tool rounds kept**, and a batch cut short keeps the calls that already produced a result (`rollback_tail`; written to the store, so a resume continues from them instead of re-running them) — side effects are not re-run on `/retry`, and only unfinished assistant text is dropped; Ctrl+C cancels the in-flight turn (a session-scoped asyncio SIGINT handler routes it, `cli/interrupt.py` — a stray Ctrl+C while the loop waits never tears the REPL down); TTY confirms/ask prompts run off-loop and register their own SIGINT target, so Ctrl+C there cancels just the poll-based read (`wait` reports `cancelled by user`) or is ignored with a hint for readline prompts (`ask_user_*`, confirms) — never the turn, never the loop; auto-retry waits 5s/10s/15s/20s then +10s (10 attempts), its countdown is Ctrl+C-cancellable, and the budget **resets when an attempt completes a model round** (connection recovered); then `/retry`.
 - Pretty tool lines: every builtin tool prints its `* Verb 'target' ` prefix as the call starts and appends the outcome (`L1-4 (done)`, `(exit code 0)`, `(session 3)`) when the result lands, so a blocking tool stays visible while it runs; namespaced MCP tools share one generic line (`* MCP <server>:<tool> (done)`). Plugin tools and custom tool calls keep the `[tool] …` / `[tool ok] …` whole-line style. Interactive TTY only (`interactive_terminal()`): piped/plain output and `--verbose` keep whole lines. A second call of the same round holds its prefix back until the open row takes its own detail (results arrive in call order), so each call still prints one finished row; a prompt box (or other output) printed while the tool runs *ends* the open prefix as its own line and falls back to whole lines for the rest of the batch — the cursor is never moved, so a prefix wider than the terminal cannot be half-erased. A batch (one round's calls) that only touches todo tools prints one `* Todo x<N>: Push, Update` line plus its last result, whose text already carries the final stack, instead of one header and a full list render per call.
 - **`plyngent providers`**, **`config path|edit`**. Config open: `$VISUAL`/`$EDITOR` (wait), else system default (`xdg-open` / `open` / `startfile`, non-blocking). `/edit` stays blocking-only. No providers → optional edit then reload when waited.
