From c0c01564687c1c0000ece811f48b0378b6cffb21 Mon Sep 17 00:00:00 2001 From: curo1305 Date: Sun, 17 May 2026 15:35:20 +0200 Subject: [PATCH] =?UTF-8?q?feat(plugins):=20Stage=202.1=20=E2=80=94=20plug?= =?UTF-8?q?in=20framework=20and=20AI=20tool-use?= MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Introduces a standalone plugin system where every integration lives as an independent Python script in ~/.pyra/plugins/, not hardcoded in core. Plugin framework (src/pyra/plugins/): - base.py: Tool dataclass, PyraPlugin Protocol, BasePlugin helper - loader.py: importlib-based discovery; one bad plugin never crashes pyra - registry.py: singleton aggregating tools, slash commands, system prompts - executor.py: approval gate — scans args, prompts y/N, scans result, logs - install.py: copies bundled_plugins/ to ~/.pyra/plugins/ on install Chat integration: - AI tool-use loop (litellm function calling, up to 10 iterations) - Plugin system prompt additions injected per session - Plugin slash commands merged with static commands CLI additions: - pyra plugin list/install/enable/disable/setup - pyra daemon start/stop/status/restart/install/uninstall (stubs for 2.4) Config: PluginConfig + DaemonConfig added to PyraConfig (backwards-compatible) Bootstrap: ~/.pyra/plugins/ and ~/.pyra/logs/ created on startup Security: tool args and results always injection-scanned; plugin dirs validated with assert_safe_path() before loading (symlink protection) Tests: 37 new tests (loader, registry, executor, plugin isolation security) 161 total, all passing.
