* feat(agent-core): repair malformed tool args JSON
Attempt jsonrepair when tool call arguments fail JSON.parse, then continue schema validation. Return malformed JSON errors with a concise expected schema hint so the model can retry with corrected arguments.
* chore(nix): update pnpm deps hash
Update the fixed-output pnpmDeps hash after adding jsonrepair so the Nix build can fetch dependencies.
* refactor(agent-core): drop tool args JSON repair
Stop repairing malformed tool call arguments. Fall back to an empty object on JSON parse failure and let schema validation produce the retry error, while preserving valid arguments for unknown tools in the transcript.
* chore: add changeset for tool args validation
* feat: add shell mode (`!`) to the CLI
Add shell mode, letting users run shell commands directly from the prompt
with `!`. Output streams live into the transcript, supports backgrounding
(ctrl+b), cancellation (Esc / Ctrl+C), input queuing while running, and
enters the conversation context with resume support.
* feat(kimi-code): show shell mode label on editor border and add tip
Render a "! shell mode" label on the top-left of the editor border while the editor is in `!` bash mode, so the active mode is visible at a glance. Also add a rotating toolbar tip (`! to run a shell command`) to surface the feature.
* feat(kimi-code): refine shell mode queue, history, and display
- Keep `!` commands out of input history so they never resurface as bare text stripped of their `!`.
- Make `!` commands non-steerable: Ctrl-S skips them (they stay queued to run after the current task) and the steer hint is only shown when something is actually steerable.
- Render queued `!` commands with a `$` prompt and the shell-mode hue so they read as commands, not as text to send to the model.
- Echo executed shell commands with a `$` prompt instead of `!`.
* fix(kimi-code): sanitize shell output and harden rendering
Captured shell command output can contain terminal control sequences (colours, cursor moves, alternate-screen switches, OSC hyperlinks, carriage-return spinners, bells). pi-tui's Text passes strings straight to the terminal, so any unhandled sequence was executed by the terminal and fought with pi-tui's own cursor control, producing the blank-screen-plus-leftover-characters mess after running commands like pnpm dev or a nested TUI.
- Sanitize CSI (incl. private modes), OSC, single-char ESC and C0 control chars (keeping newline and tab) in both the finished/resume view (previously unsanitized) and the running tail.
- Make the sanitize, format, and ShellRunComponent render paths never-throw, and cap the live running buffer, so a misbehaving command cannot crash the TUI.
- Dispose transcript children on clear so ShellRunComponent's timer is released on /clear or session switch.
* fix(kimi-code): render shell command echo with $ instead of sparkles
The shell command echo is a 'user' transcript entry, so UserMessageComponent prefixed it with the USER_MESSAGE_BULLET (sparkles), producing 'sparkles $ command'.
Add an optional bullet override to UserMessageComponent / TranscriptEntry and set it to an empty string for the shell echo (both live and resume), so the '$ command' content sits at the leading column where the sparkles marker used to be. Normal user messages keep the sparkles bullet.
* fix(kimi-code): enter shell mode when pasting a !-prefixed command
The bash-mode trigger only handled the single ! keystroke, so a pasted !cmd was inserted as literal text in prompt mode and submitted as a normal message.
After pi-tui inserts pasted content, detect an empty-prompt buffer that now starts with !, switch to bash mode, and strip the leading ! so the buffer holds only the command, matching the typed ! path.
* fix(kimi-code): restore shell mode when recalling a queued command
recallLastQueued() dropped the queued item's mode, and the Up-arrow recall only restored the text. A queued ! command (queued while another command runs, which resets the editor to prompt mode) therefore came back as a normal prompt and was submitted as a message instead of a shell command.
Return the full QueuedMessage from recallLastQueued() and restore editor.inputMode (plus the onInputModeChange sync) from the recalled item's mode.
* feat(kimi-code): use violet as the shell mode color
Replace the claude-code-style magenta/rose shellMode token with a violet that is distinct from plan-mode blue, the user role amber, success green, error red, and the teal accent.
Custom themes that omit the token fall back to this new default via the base+overrides merge, so existing custom themes keep working unchanged.
* chore: refine the shell mode changeset
* docs: document shell mode
Add a Shell mode section to the interaction guide and list the ! and Ctrl+B shortcuts in the keyboard reference, in both English and Chinese.
* test(protocol): include shell events in volatile classification check
shell.output and shell.started were added as volatile event types for shell mode; update the snapshot test's volatile-type list and count accordingly.
* fix(agent-core): surface shell command failure reason with no output
When a ! shell command fails without producing stdout/stderr (non-zero exit with no output, timeout, spawn failure), the failure reason lived only in the tool result's output and the TUI showed '(no output)'. Fold it into stderr so the live view and replay show what went wrong.
* fix(kimi-code): decode CSI-u ! to enter shell mode
In terminals with the Kitty keyboard protocol (VSCode integrated terminal, Kitty), pressing ! arrives as a CSI-u sequence, so the raw normalized === '!' comparison never matched and shell mode could not be entered by typing !. Decode with printableChar before comparing, matching every other printable-key check in the TUI.
* fix(kimi-code): do not steer while a shell command is running
Ctrl-S steers queued input into the running turn, but a shell command is not an agent turn, so steering during streamingPhase === 'shell' would launch a turn before the command output is recorded. Keep Ctrl-S a no-op during shell runs; queued messages stay queued.
* fix(agent-core): escape bash tag delimiters in shell output
Shell command output is arbitrary text; if it contains a bash tag delimiter such as </bash-stdout>, the recorded pseudo-XML wrapper breaks and replay extracts the wrong slice. Escape the content when wrapping it in agent-core and unescape when extracting during replay, so output survives round-trip intact.
* docs: document the shellMode theme token
The shellMode color token was added to the palette but not propagated to its mirrors. Add it to the custom-theme docs token table, the theme JSON schema, and the custom-theme skill token list.
* feat(agent-core): reset background task deadline on detach
Add a resettable deadline timer to BackgroundManager and let tasks register a detach timeout; when a foreground task is moved to the background, its deadline resets to the background default counted from the detach moment.
Wire this into shell mode so ! commands run with a 3-minute foreground timeout and get 10 minutes once detached to the background, instead of staying bounded by the original 60-second foreground deadline.
* feat(agent-core): lower shell mode foreground timeout to 2 minutes
* feat(agent-core): add dead-end detection for repeated tool calls
- inject stronger dead-end reminder at streak 10 and force-stop turn at streak 15
- emit `tool_call_repeat` telemetry events for streak >= 2
- pass telemetry client from TurnFlow to ToolCallDeduplicator
- add comprehensive tests for dead-end stop and telemetry behavior
* fix(agent-core): tune tool-dedup thresholds and preserve isError state
- Lower repeat-reminder thresholds to 3, 5, 8 and force-stop to 12
- Force-stop no longer overrides successful tool results to isError
- Move stopTurn field into ExecutableToolSuccessResult for explicit loop-control without requiring isError
When the user interrupts running tools or parallel subagents, the tool_result
fed back to the model was a neutral `Tool "X" was aborted` or a weak "stopped by
the user", so the model treated it as a system fault and speculated about
capacity/concurrency limits instead of recognizing a deliberate stop.
Carry a UserCancellationError as the AbortSignal reason from the cancel sites
(Turn.cancel/abortTurn, SessionSubagentHost.cancelAll) through to the message
sites (tool-call settle paths and the AgentTool catches), which now emit an
explicit "deliberate user action, not a system error/timeout/capacity limit"
message. Aborts propagated from another signal (e.g. a subagent's deadline via
waitForCurrentTurn) carry their original reason, so a timeout is not mislabeled
as a user interruption. The telemetry outcome classifier matches the new
"manually interrupted" phrase to keep counting these as cancelled.
Merge turnId/step into a single `turnStep` field ("0.1") and
attempt/maxAttempts into `attempt` ("2/3"), and drop the
messageCount/toolCallCount fields. The per-request `llm request`
line goes from up to 8 fields down to ~3; the `llm config` line
(including thinkingEffort, logged for all providers) is unchanged.
* fix(agent-core): always pair tool.call with tool.result on malformed returns
A tool returning undefined, a primitive, or an object without a valid
output field crashed normalization, exited the batch loop without
dispatching the matching tool.result, and left the next provider
request to fail with a missing tool_call_id response.
- Validate the tool return at the boundary in runRunnableToolCall via a
new coerceToolResult helper; malformed returns become an isError
result.
- Harden normalizeToolResult and toolResultStopsTurn against
non-conformant input from synthetic results or finalize hooks.
- Track unpaired tool.call ids in runToolCallBatch and emit
compensating error results in finally for any that did not receive a
result.
* refactor(agent-core): simplify tool result pairing
Drop the unpairedCallIds tracking and finally-compensation wrapper from
runToolCallBatch. The set was updated before dispatchEvent, so a failure
between the two left it inconsistent; the per-call try/catch already
produces a paired error result, making the outer wrapper redundant.
Coerce hook returns at the synthetic and finalizeToolResult boundaries
so a malformed hook output is normalized into a paired error result the
same way a malformed tool return already is.
