This caused the summary to be permanently lost after a process restart, making the AI forget archived context and appear to ignore memory or reference non-existent previous messages. Replace the destructive pop with a _last_summary_used sentinel: - _last_summary stays in metadata for restart survival - _last_summary_used prevents duplicate injection within the same turn - Clear the sentinel whenever a new summary is generated Updates tests to match the new persistence behavior. --- nanobot/agent/autocompact.py | 13 +++++++----- nanobot/agent/memory.py | 1 + tests/agent/test_auto_compact.py | 21 ++++++++++++------- tests/agent/test_loop_consolidation_tokens.py | 5 ++++- 4 files changed, 27 insertions(+), 13 deletions(-) diff --git a/nanobot/agent/autocompact.py b/nanobot/agent/autocompact.py index eabd86155..fa4af0efb 100644 --- a/nanobot/agent/autocompact.py +++ b/nanobot/agent/autocompact.py @@ -89,6 +89,7 @@ class AutoCompact: if summary and summary != "(nothing)": self._summaries[key] = (summary, last_active) session.metadata["_last_summary"] = {"text": summary, "last_active": last_active.isoformat()} + session.metadata.pop("_last_summary_used", None) session.messages = kept_msgs session.last_consolidated = 0 session.updated_at = datetime.now() @@ -111,13 +112,15 @@ class AutoCompact: logger.info("Auto-compact: reloading session {} (archiving={})", key, key in self._archiving) session = self.sessions.get_or_create(key) # Hot path: summary from in-memory dict (process hasn't restarted). -

Drops the uv cache which broke last time because uv.lock is gitignored in this repo, and keeps lint as a step inside the test job (matching the pre-c01f8599 layout). What's added (all metadata-only, no external dependencies): - concurrency: cancel superseded runs on the same ref - permissions: tighten GITHUB_TOKEN to contents: read - timeout-minutes: 20 to bound runaway jobs - fail-fast: false so all matrix combinations surface failures - matrix conditional: PRs run Linux x {3.11, 3.14} for fast feedback; push to main/nightly still runs the full 2-OS x 4-Python matrix What's intentionally NOT added (each removed for a reason): - uv cache: depends on uv.lock which is gitignored - separate lint job: kept inline as a step, matches original - workflow_dispatch / paths-ignore: scope creep, not needed now All jobs continue to run on standard GitHub-hosted runners (ubuntu-latest, windows-latest), keeping CI within the free tier.

Append [Archived Context Summary] to system prompt instead of injecting it into the user message runtime context, improving KV cache reuse across turns and avoiding consecutive same-role messages. - _last_summary persists in metadata (no pop) for restart survival; summary is re-injected every turn via the stable system prompt. - Remove dynamic "Inactive for X minutes" from _format_summary — use static last_active timestamp instead to preserve KV cache stability. - Pass session_summary through build_messages() so both normal and ask_user paths receive the archived summary in the system prompt. - estimate_session_prompt_tokens now reads _last_summary from metadata to include the summary in token budget estimation. - Remove obsolete session_summary parameter from maybe_consolidate_by_tokens and estimate_session_prompt_tokens call sites in loop.py (summary flows through build_messages instead). -

Key changes: - Add Tool ABC metadata (tool_name, _scopes) and ToolContext dataclass for dependency injection. - Introduce ToolLoader with pkgutil-based builtin discovery and entry_points-based third-party plugin loading. - Add scope filtering (core/subagent/memory) so different contexts load appropriate tool sets. - Introduce ContextAware protocol and RequestContext dataclass to replace hardcoded per-tool context injection in AgentLoop. - Add RuntimeState / MutableRuntimeState protocols to decouple MyTool from AgentLoop. - Migrate all built-in tools to declare scopes and implement create()/enabled() hooks. - Migrate MessageTool, SpawnTool, CronTool, and MyTool to ContextAware. - Refactor AgentLoop to use ToolLoader and protocol-driven context injection. - Refactor SubagentManager to use ToolLoader(scope="subagent") with per-run FileStates isolation. - Register all built-in tools via pyproject.toml entry_points. - Add comprehensive tests for loader scopes, entry_points, ContextAware, subagent tools, and runtime state sync. --- .gitignore | 5 + nanobot/agent/loop.py | 152 ++----- nanobot/agent/subagent.py | 80 ++-- nanobot/agent/tools/__init__.py | 4 + nanobot/agent/tools/base.py | 34 +- nanobot/agent/tools/context.py | 34 ++ nanobot/agent/tools/cron.py | 26 +- nanobot/agent/tools/filesystem.py | 33 +- nanobot/agent/tools/image_generation.py | 33 +- nanobot/agent/tools/loader.py | 116 +++++ nanobot/agent/tools/mcp.py | 6 + nanobot/agent/tools/message.py | 25 +- nanobot/agent/tools/notebook.py | 1 + nanobot/agent/tools/runtime_state.py | 54 +++ nanobot/agent/tools/search.py | 3 + nanobot/agent/tools/self.py | 83 ++-- nanobot/agent/tools/shell.py | 42 ++ nanobot/agent/tools/spawn.py | 22 +- nanobot/agent/tools/web.py | 78 +++- nanobot/channels/websocket.py | 4 + nanobot/config/paths.py | 11 +- nanobot/config/schema.py | 123 +++--- pyproject.toml | 5 + tests/agent/test_context_aware.py | 23 + tests/agent/test_dream_tools.py | 19 + tests/agent/test_loop_tool_context.py | 21 +- tests/agent/test_subagent.py | 30 ++ tests/agent/test_task_cancel.py | 14 +- tests/agent/test_tool_loader_entrypoints.py | 76 ++++ tests/agent/test_tool_loader_scopes.py | 77 ++++ tests/agent/tools/test_self_tool.py | 68 +-- .../tools/test_self_tool_runtime_sync.py | 2 +- tests/agent/tools/test_subagent_tools.py | 9 +- tests/cron/test_cron_tool_list.py | 15 +- tests/cron/test_cron_tool_schema_contract.py | 3 +- tests/test_tool_contextvars.py | 19 +- tests/tools/test_exec_platform.py | 4 +- tests/tools/test_message_tool.py | 12 +- tests/tools/test_message_tool_suppress.py | 3 +- tests/tools/test_tool_loader.py | 413 ++++++++++++++++++ 40 files changed, 1404 insertions(+), 378 deletions(-) create mode 100644 nanobot/agent/tools/context.py create mode 100644 nanobot/agent/tools/loader.py create mode 100644 nanobot/agent/tools/runtime_state.py create mode 100644 tests/agent/test_context_aware.py create mode 100644 tests/agent/test_dream_tools.py create mode 100644 tests/agent/test_subagent.py create mode 100644 tests/agent/test_tool_loader_entrypoints.py create mode 100644 tests/agent/test_tool_loader_scopes.py create mode 100644 tests/tools/test_tool_loader.py diff --git a/.gitignore b/.gitignore index 054e5ce70..81127ad11 100644 --- a/.gitignore +++ b/.gitignore @@ -1,11 +1,16 @@ # Project-specific .worktrees/ +.worktree/ .assets .docs .env .web .orion +# Claude / AI assistant artifacts +docs/superpowers/ +docs/plans/ + # webui (monorepo frontend) webui/node_modules/ webui/dist/ diff --git a/nanobot/agent/loop.py b/nanobot/agent/loop.py index da05cfbf6..bb33868db 100644 --- a/nanobot/agent/loop.py +++ b/nanobot/agent/loop.py @@ -20,27 +20,17 @@ from nanobot.agent.context import ContextBuilder from nanobot.agent.hook import AgentHook, AgentHookContext, CompositeHook from nanobot.agent.memory import Consolidator, Dream from nanobot.agent.runner import _MAX_INJECTIONS_PER_TURN, AgentRunner, AgentRunSpec -from nanobot.agent.skills import BUILTIN_SKILLS_DIR from nanobot.agent.subagent import SubagentManager from nanobot.agent.tools.ask import ( -
