Release v2.0.0

What's changed

✂️ Updated Features

• Reframed from an OpenAI-Assistant shell into a provider-agnostic library of safe,
• token-aware filesystem tools for any LLM agent.
• Unified diffs are now the primary edit path: apply_git_patch validates that
• every target file is inside the root folder, and (when auto_cat is on) returns
• the patched file contents so a clean exit isn't mistaken for a correct edit.
• Tools are now invoked through a neutral ToolKit.dispatch(name, arguments)
• instead of an OpenAI-run object.
• The TODO task store now lives at ai_shell.todo and is stored as Markdown with
• YAML frontmatter (TODO.md / TODO_done.md) instead of a private TOML format.
• Tasks gained a done_when acceptance-criteria field for the goal loop.
• Read-only git tools now shell out to the git CLI; gitpython is no longer a
• direct dependency.
• Linters/formatters/test-runners are now an optional checkers extra rather than
• required dependencies.
• Packaging migrated from Poetry to standard PEP 621 (uv).

🚫 Removed

• The OpenAI Assistants (Beta) bot runtime: TaskBot, the tool loop, the demo
• bots, the markdown dialog logger, and the openai / openai_multi_tool_use_parallel_patch
• dependencies. Bring your own agent loop.
• The ed and edlin line-editor tools — edit via unified diffs (apply_git_patch)
• or replace/insert/rewrite instead.
• Unimplemented stubs (regex-tester, tool-picker sub-bot) and their config flags.
• The OpenAI-API JSON request logger and bundled sample logs / demo fixtures.
• bug-trail-core, markpickle, and doc-only markdown dependencies from the core
• install.
