Move the fenced-code-block-aware splitting logic out of the shared
split_message helper (used by Signal, Slack, Discord, Weixin, etc.)
and into a Telegram-specific _split_telegram_markdown function.
The shared split_message remains a plain-text chunker. The Telegram
channel now uses _split_telegram_markdown for its raw Markdown paths
that feed _markdown_to_telegram_html, preventing broken HTML rendering
when splits fall inside fenced code blocks.
Also fixes a regression where content beginning with whitespace before
a fence could emit a whitespace-only chunk.
Addresses review feedback on #4257.
When split_message splits a long message, it now checks whether the
split point falls inside a fenced code block. If so, it either moves
the split to before the opening fence or closes/reopens the fence
across chunks, preventing broken HTML rendering.
Addresses #4250
Extract is_image_file() and reference_non_image_attachments() from
AgentLoop private static methods into nanobot/utils/document.py where
they belong alongside extract_documents(). Simplify config lookup by
removing dead isinstance(dict) branch.
Remove standalone nanobot/heartbeat/ service and replace it with an
auto-registered system cron job on gateway startup. Key behaviors preserved:
- HeartbeatConfig (enabled, interval_s, keep_recent_messages) remains in
GatewayConfig for backward compatibility.
- On startup, if enabled, a system cron job "heartbeat" is registered with
schedule derived from interval_s.
- HEARTBEAT.md is checked on each tick; empty/template-identical files skip
to avoid wasting LLM calls.
- Post-run evaluate_response and session history truncation
(keep_recent_messages) are retained.
- Delivery target selection, deliverable filtering, and preamble guidance
are preserved.
Files removed:
- nanobot/heartbeat/__init__.py
- nanobot/heartbeat/service.py
- tests/heartbeat/*
- tests/agent/test_heartbeat_service.py
Templates and docs updated to reflect cron-based usage.
`long_task` registers a sustained objective, but `AgentRunner` would
still exit with `stop_reason="completed"` when the LLM produced a final
text response without calling `complete_goal`. This defeated the purpose
of sustained goals.
Add `goal_active_predicate` and `goal_continue_message` to `AgentRunSpec`.
When the predicate returns `True` at the natural completion checkpoint,
inject a continuation message via the existing `_try_drain_injections`
machinery, forcing the runner to continue looping.
Also extract the default continuation prompt to
`nanobot/utils/runtime.py` alongside the existing recovery-message
builders.
Drop the legacy unified-diff patch parameter and all related parsing/
generation logic (_parse_patch, _generate_patch, _apply_hunks, etc.).
The tool now accepts only the structured `edits` array, eliminating the
intermediate diff-string round-trip.
Also update file_edit_events tracking and tests to work exclusively
with edits.
Benchmark (zhipu glm-5.1, edits mode): 15/15 cases passed.
- Remove generated_image_paths_from_messages() and _extract_text_payload() from artifacts.py (no runtime callers)
- Remove session_attachments.py entirely (merge_turn_media_into_last_assistant and stage_media_paths_for_session_replay had no runtime callers)
- Remove test_session_media_persist.py and the orphaned test in test_artifacts.py
The runtime media-attachment mechanism was broken for streaming channels
(e.g. WebSocket): the _streamed flag caused _send_once to skip the final
OutboundMessage that carried generated media, so images were never delivered.
Rather than adding complex coordination between streaming and media delivery,
delegate image delivery to the LLM: after generate_image returns artifact
paths, the next_step prompt now instructs the LLM to call the message tool
with the paths in the media parameter. This works uniformly across all
channels, streaming or not.
Remove generated_media from TurnContext, _assemble_outbound, and _state_save.
Update prompts in identity.md, SKILL.md, message tool description, and
artifacts.py to reflect the new flow.
* feat(long-task): add LongTaskTool for multi-step agent tasks
Implements a meta-ReAct loop where long-running tasks are broken into
sequential subagent steps, each starting fresh with the original goal
and progress from the previous step. This prevents context drift when
agents work on complex, multi-step tasks.
- Extract build_tool_registry() from SubagentManager for reuse
- Add run_step() for synchronous subagent execution (no bus announcement)
- Add HandoffTool and CompleteTool as signal mechanisms via shared dict
- Add LongTaskTool orchestrator with simplified prompt (8 iterations/step)
- Register LongTaskTool in main agent loop
- Add _extract_handoff_from_messages fallback for robustness
* fix(long-task): add debug logging for step-level observability
* feat(long-task): major overhaul with structured handoffs, validation, and observability
- Structured HandoffState: HandoffTool now accepts files_created,
files_modified, next_step_hint, and verification fields instead of
a plain string. Progress is passed between steps as structured data.
- Completion validation round: After complete() is called, a dedicated
validator step runs to verify the claim against the original goal.
If validation fails, the task continues rather than returning
a false completion.
- Dynamic prompt system: 3 Jinja2 templates (step_start, step_middle,
step_final) selected based on step number. Final steps get tighter
budget and stronger "wrap up" guidance.
- Automatic file change tracking: Extracts write_file/edit_file events
from tool_events and injects them into the next step's context if
the subagent forgot to report them explicitly.
- Budget tracking & adaptive strategy: Cumulative token usage is tracked
across steps. Per-step tool budget drops from 8 to 4 in the last
two steps to force handoff/completion.
- Crash retry with graceful degradation: A step that crashes is retried
once. Persistent crashes terminate the task and return partial progress.
- Full observability hooks for future WebUI integration:
- set_hooks() with on_step_start, on_step_complete, on_handoff,
on_validation_started, on_validation_passed, on_validation_failed,
on_task_complete, on_task_error, and catch-all on_event.
- Readable state properties: current_step, total_steps, status,
last_handoff, cumulative_usage, goal.
- inject_correction() allows external code to send user corrections
that are injected into the next step's prompt.
- run_step() accepts optional max_iterations for dynamic budget control.
All 27 long-task tests and 11 subagent tests pass.
* test(long-task): add boundary tests and fix race conditions
- Add 7 edge-case tests: validation crash resilience, hook exception safety, mid-run correction injection, FIFO correction ordering, explicit file changes overriding auto-detection, final budget for max_steps=1, and dynamic budget switching boundaries
- Fix assertion in test_long_task_completes_after_multiple_handoffs to match exact prompt format
- Remove asyncio timing hack from test_state_exposure
- Add asyncio.sleep(0) yield in test_inject_correction_during_execution to prevent race between signal injection and step continuation
- All 34 tests passing
* fix(long-task): address code review findings
- Declare _scopes = {"core"} explicitly to prevent recursive nesting in subagent scope
- Document fragile coupling in _extract_file_changes: path extraction depends on
write_file/edit_file detail format; add debug log for unexpected formats
- Align final-template threshold (max_steps - 2) with budget switch threshold
- Eliminate hasattr(self, "_state") in _reset_state by initializing in __init__
* fix(long-task): honor final signal and file tracking
Co-authored-by: Cursor <cursoragent@cursor.com>
* feat(long-task): improve prompt structure and agent contract
- Expand LongTaskTool.description to instruct parent agent on goal
construction, return value semantics, and how to handle results.
- Expand CompleteTool.description to emphasize that the summary IS the
final answer returned to the parent agent.
- Prefix validated return value with an explicit "final answer" directive
to stop parent agent from re-running work.
- Redesign step_start.md: Step 1 is now explicitly for exploration,
planning, and skeleton-building. complete() is discouraged.
- Remove bulky payload debug logging from _emit(); add targeted
info/warning/error logs at key state transitions instead.
- Add signal_type to HandoffState for cleaner signal detection.
* test(long-task): expect wrapped completion message after validation
Align assertions with LongTaskTool final return shape on main.

* feat(webui): turn timing strip, latency, and session-switch restore
- Agent loop: publish goal_status run/idle for WebSocket turns; attach
wall-clock latency_ms on turn_end and persisted assistant metadata.
- WebSocket channel: forward goal_status and latency fields to clients.
- NanobotClient: track goal_status started_at per chat without requiring
onChat; useNanobotStream restores run strip when returning to a chat.
- Thread UI: composer/shell viewport hooks for run duration and latency;
format helpers and i18n strings.
- MessageBubble: drop trailing StreamCursor (layout artifact vs block markdown).
- Builtin / tests: model command coverage, websocket and loop tests.
Covers multi-session UX and round-trip timing visibility for the WebUI.
Co-authored-by: Cursor <cursoragent@cursor.com>
* fix: keep message-tool file attachments after canonical history hydrate
- MessageTool records per-turn media paths delivered to the active chat.
- nanobot.utils.session_attachments stages out-of-media-root files and
merges into the last assistant message before save (loop stays a thin call).
- WebUI MediaCell: use a signed URL as a real download link when present.
Fixes attachments flashing then vanishing on turn_end when paths lived
outside get_media_dir (e.g. workspace files).

* feat(long_task): cumulative run history, file union, and prompt tuning
Inject cross-step summaries and merged file paths into middle/final step

block when it duplicates Previous Progress to save tokens. Add optional
cumulative_prompt_max_chars and cumulative_step_body_max_chars parameters
with clamped defaults.

* fix(webui): session switch keeps in-flight thread and replays buffered WS
Save the prior chat message list to the per-chat cache in a layout effect
when chatId changes (before stale writes could corrupt another chat).
Skip one post-switch layout cache tick so we do not snapshot the wrong tab.
Buffer inbound events per chat_id when no onChat subscriber is registered
(e.g. user focused another session) and drain on resubscribe up to a cap,
so streaming deltas are not lost while off-tab.

* fix(webui): snap thread scroll to bottom on session open (no smooth glide)
Use scroll-behavior auto on the viewport, instant programmatic scroll when
following new messages and on scrollToBottomSignal. Keep smooth only for
the explicit scroll-to-bottom button.

* fix(webui): respect manual scroll-up after opening a session
Track when the user leaves the bottom with a ref and skip ResizeObserver
and deferred bottom snaps until they return or the conversation is reset.
Remove the time-based force-bottom window that overrode atBottom.
Multi-frame scrollToBottom honours the same guard unless force (scroll button).

* feat: WebUI long_task activity card and resilient history merge
Add optional ui_summary to the long_task tool for one-line UI labels. Stream
long_task agent_ui into a dedicated message row with timeline, markdown peek,
and a right sheet for details. Merge canonical history after turn_end while
re-inserting long_task rows before the final assistant reply. Collapse
duplicate task_start/step_start steps in the timeline and extend i18n.

GlobTool is redundant — GrepTool already supports glob-based file
filtering via its `glob` parameter, making a standalone glob-only
tool unnecessary. Removing it simplifies the tool surface and reduces
LLM confusion between glob and grep.
Resolves conflicts after main landed the state-machine turn refactor
and the test_runner.py 9-file split:
- nanobot/agent/loop.py: take main's `_state_build`/`_persist_user_message_early`
flow; restore the `reasoning: bool` parameter on `_build_bus_progress_callback`
so the loop hook can mark progress as reasoning-channel without coupling to
the answer stream.
- nanobot/cli/stream.py: keep main's configurable `bot_name`/`bot_icon` header
while preserving the PR's `transient=True` Live + `self._console` routing
+ `_renderable()` final-render path that fixed TUI duplication.
- tests/agent/test_runner.py was deleted on main and split into 9 focused
files; relocated all 6 reasoning tests into a new `test_runner_reasoning.py`
matching the new layout, deduplicated the per-test `ReasoningHook` boilerplate
through a shared `_RecordingHook` helper.

Reasoning surfacing was split across three branches in runner.py plus
two separate streaming buffers (loop hook and runner progress stream),
with three independent display-side gates in the CLI. This collapsed
the policy into one source of truth and fixed two real bugs:
- Structured `reasoning_content` was suppressed whenever the answer was
streamed, because the runner gated emission on `streamed_content`.
Providers don't stream `reasoning_content`; it only arrives on the
final response, so the answer stream and the reasoning channel are
independent. Added `streamed_reasoning` to `AgentHookContext` to track
the right bit.
- `channels.showReasoning` was subordinated to `sendProgress`. They are
orthogonal — turning off progress streaming shouldn't silence
reasoning. Reworked the CLI gates accordingly.
Single-helper consolidation:
- `extract_reasoning(reasoning_content, thinking_blocks, content)`
returns `(reasoning_text, cleaned_content)` with a defined fallback
order: dedicated field → Anthropic thinking_blocks → inline
`<think>`/`<thought>` tags. Models that expose none of these
short-circuit to `(None, content)` — zero overhead.
- `IncrementalThinkExtractor` replaces the ad-hoc `emit_incremental_think`
function and its hand-rolled "emitted cursor" state in both the loop
hook and the runner progress stream.
Also documented the new `showReasoning` channel option in
docs/configuration.md and noted its independence from sendProgress.

Add extract_think() and emit_incremental_think() helpers to extract thinking content from inline <think> and <thought> tags in the content field. This handles models served via Ollama, self-hosted vLLM, or other compatible endpoints that embed reasoning as inline tags instead of using the dedicated reasoning_content API field.
Also adds Anthropic thinking_blocks support for extended thinking via the thinking content blocks array.

The is_path branch in _fmt_known was not passing max_length to
abbreviate_path, so read_file, write_file, edit, list_dir, and
web_fetch always truncated paths at 40 chars regardless of config.
Now all three branches (is_path, is_command, fallback) honor the
configured toolHintMaxLength.
Add to config (default: 40, range: 20-500).
Controls how many characters of tool hints are shown in progress updates
(e.g. '$ cd …/project && npm test').
Set to 120+ to see full commands instead of truncated hints:
```json
{
"agents": {
"defaults": {
"toolHintMaxLength": 120
}
}
}
```
- Thread max_length through format_tool_hints → _fmt_known/_fmt_mcp/_fmt_fallback
- Make path abbreviation in _abbreviate_command proportional to max_length
- Add TestToolHintMaxLength test class with 5 tests
- All 41 existing tests pass
Keep the workspace-boundary changes easier to review by trimming long explanatory comments down to short local notes. Also make the #3599 POSIX command regression skip on Windows and normalize workspace violation signatures to POSIX separators so the throttle tests are platform-stable.

Replaces PR #3493's blanket fatal abort with a "tell the model + throttle
the bypass loop" policy. Workspace-bound rejections are now ordinary
recoverable tool errors enriched with a structured "this is a hard policy
boundary" instruction; SSRF stays the only marker that aborts the turn.
Why the fatal-abort approach broke
----------------------------------
PR #3493 promoted every shell `_guard_command` and filesystem path-resolution
rejection to a turn-fatal RuntimeError. Two of those messages (`path
outside working dir` and `path traversal detected`) are heuristic substring
scans on the raw command, so legitimate commands like `rm <ws>/x.txt
2>/dev/null` or `find . -type f` killed the user's turn (#3599). On
channels with outbound dedupe (Telegram) the user just saw silence (#3605),
and the noise polluted the LLM's context until it started hallucinating
guard rejections on plain relative paths (#3597).
Why we still need *some* throttle
---------------------------------
The original #3493 pain point was real: the LLM, refused once, would
swap tools and try again -- read_file -> exec cat -> exec cp -> bash -c
-> ln -sf -> python -c open(...). Just removing the fatal escape lets
that loop run wild until max_iterations.
What this commit does
---------------------
- `nanobot/utils/runtime.py`: add `workspace_violation_signature` and
`repeated_workspace_violation_error`. The signature normalizes
filesystem `path` arguments and the first absolute path inside an
exec command, so swapping tools against the same outside target hits
the same throttle bucket. Two soft attempts are allowed; the third
attempt's tool result is replaced with a hard "stop trying to bypass"
message that quotes the target path and tells the model to ask the
user for help.
- `nanobot/agent/runner.py`: split classification into `_is_ssrf_violation`
(still fatal) and `_is_workspace_violation` (now soft). All three
failure branches in `_run_tool` (prep_error / exception / Error
result) route through a shared `_classify_violation` that bumps the
per-turn workspace_violation_counts dict and either keeps the tool's
own message or substitutes the throttle escalation. `_execute_tools`
now threads that dict alongside the existing external_lookup_counts.
- `nanobot/agent/tools/shell.py`: append a structured boundary note to
every workspace-bound guard rejection (`working_dir could not be
resolved`, `working_dir is outside`, `path outside working dir`,
`path traversal detected`). SSRF errors stay short and direct so the
model doesn't try to "phrase around" them. Existing `2>/dev/null`
allow-list and benign device passthrough from the previous commit
remain.
- `nanobot/agent/tools/filesystem.py`: append the same boundary note to
the `outside allowed directory` PermissionError so read_file / write_file
/ list_dir errors give the LLM the same explicit hint.
Tests
-----
- `tests/utils/test_workspace_violation_throttle.py` (new): signature
collapses across read_file/exec/python -c against the same path,
different paths get independent budgets, escalation only fires after
the third attempt.
- `tests/agent/test_runner.py`:
- `test_runner_does_not_abort_on_workspace_violation_anymore` -- v2
contract: filesystem PermissionError is now soft, runner moves to
the next iteration and finalizes cleanly.
- `test_is_ssrf_violation_remains_fatal` + the existing
`test_runner_aborts_on_ssrf_violation` -- SSRF still aborts on the
first attempt.
- `test_runner_lets_llm_recover_from_shell_guard_path_outside` -- end
to end recovery from `path outside working dir`.
- `test_runner_throttles_repeated_workspace_bypass_attempts` -- four
bypass attempts against the same outside target produce at least
one `workspace_violation_escalated` event and the run completes
naturally without aborting the turn.
- The two `_execute_tools` direct-call tests now pass the new
workspace_violation_counts dict.
- `tests/tools/test_tool_validation.py`: relax three `==` assertions
to `startswith` + "hard policy boundary" substring check to match
the new structured error messages.
- `tests/tools/test_exec_security.py` keeps the prior `2>/dev/null`
regression and the `> /etc/issue` negative case from the previous
commit on this branch -- they still pass under the new policy.

cmd_restart only persisted channel + chat_id across the os.execv boundary, so
when the new process announced "Restart completed" the OutboundMessage had
no Slack thread_ts and the reply fell back to the channel root.
Serialize msg.metadata into NANOBOT_RESTART_NOTIFY_METADATA, restore it on the
RestartNotice, and forward it to OutboundMessage so the completion message
follows the same routing as the original /restart invocation.
Made-with: Cursor
Move pypdf, python-docx, openpyxl, and python-pptx imports from module
level into the _extract_pdf / _extract_docx / _extract_xlsx /
_extract_pptx functions that actually use them. These four libraries
became core dependencies in v0.1.5.post2 (~25 MB combined) and were
paying the import cost on every nanobot startup even when no document
parsing was needed for the session.
The module-level SUPPORTED_EXTENSIONS set and the extract_text()
dispatch stay as-is; the "[error: <lib> not installed]" branches move
from the old module-level None sentinels into the corresponding
extractor's try/except ImportError block. Behavior for the error
message and for successful parses is identical.
All 20 tests in tests/test_document_parsing.py pass unchanged.
