/btw now defaults to --tools=read: the side turn gets only READ_ONLY
tools under a read-only context (fetch restricted to GET), with the main
session view so read-only reads (todo_list) see real state. --tools=full
keeps the previous whole-registry clone with a fresh session; --tools=no
turns tools off. When tools are off, the default read silently falls back
to no tools, while an explicit --tools read|full errors as before.
Adds 7 unit tests for _synthetic_todo_pair_after and committed_prefix_end
with synthetic todo nag pairs: survival across rollback, detection at
correct index, immunity to real tool calls, and multiple rollbacks.
These directly verify the guard that prevents duplicate turn-start
nag injection on /retry when a synthetic pair from a previous failed
attempt survived rollback (committed tool batch).
needs_review is true for any non-empty stack so end-of-turn inject
keeps firing under synthetic_tool. Message history keeps only the last
todo-nag tool pair (dedupe by todo-nag- tool_call_id).
Remove system strategy (legacy maps to developer). synthetic_tool still
forges the call but uses real stack text as the tool result, and now
yields ToolCall/Result events so the CLI flushes and does not glue nag
text to the next assistant stream.
Split tags: [TODO OPEN WORK] for pending/in_progress (undone work) vs
[TODO HYGIENE] for all-terminal leftover groups. End-of-turn review lists
open titles; tool docs stress open items as unfinished work.
Inject turn-start [TODO REMINDER] for non-empty stacks; rewrite end-of-turn
[TODO OPEN] copy so open items read as unfinished work. needs_review now
always true while open items remain (even if todo_* ran this turn); terminal-only
stacks still need review if untouched. Update tool docs and tests.
Add prek.toml so git commit runs ruff-pre-commit (fix then format) and
pdm-based basedpyright. Document install/install-hook; clear type warnings
that made basedpyright exit non-zero under recommended mode.
TOP = last element only for pop; multi-push puts first title on top for DFS
breakdown. Dropped nested-frame model; migrate old frames JSON to flat stack.
push of one or more titles opens a new frame (siblings at one depth);
pop leaves the frame. Supports T1,T2 → T1.1,T1.2 → pop → T2.1 pattern.
Legacy flat session JSON migrates to a single root frame.
Sub-task stack stored on session.todo_stack; model tools todo_*; slash
/todos for human ops; agent loop injects a review user message when open
todos exist and no todo_* tool ran this turn. Stack carries across /compact.
After each completed assistant+tool batch, persist and keep that prefix on
failure. Rollback only unfinished assistant/stream suffix. pending_retry
and /retry also apply when history ends with tool results (continue model
without re-executing tools).
