Alessandro afff2e3c05 Harden scoped tool policy enforcement
Resolve effective policy through inherited layers without letting empty upper configs shadow restrictions, and carry canonical tool identities through local and MCP execution.

Enforce required policy hooks and parent delegation checks at runtime, keep installed connector capabilities configurable while disconnected, and remove complete blocked-tool examples from rendered prompts.

Use the canonical tool prompts for concise catalog descriptions and add regressions for plugin activation, dotted local names, MCP calls, layered policies, and parallel subordinate paths.

plugins.py DOX

Purpose

  • Own the plugins.py API endpoint.
  • This module manages plugin actions and plugin settings through the core API.
  • Keep this file-level DOX profile synchronized with plugins.py because this directory is intentionally flat.

Ownership

  • plugins.py owns the runtime implementation.
  • plugins.py.dox.md owns durable notes about responsibilities, contracts, side effects, and verification for that implementation.
  • Classes:
  • Plugins (ApiHandler)
    • async process(self, input: dict, request: Request) -> dict | Response

Runtime Contracts

  • HTTP handlers must derive from helpers.api.ApiHandler; WebSocket handlers must derive from helpers.ws.WsHandler.
  • Update this file whenever request payloads, authentication or CSRF requirements, response shapes, route side effects, or WebSocket event contracts change.
  • Plugins is an ApiHandler.
  • Plugins defines process(...).
  • Toggle requests that try to disable an always_enabled plugin return HTTP 400 without changing plugin state.
  • Observed side-effect areas: filesystem reads, filesystem writes, filesystem deletion, subprocess/runtime control, plugin state, settings/state persistence.
  • Imported dependency areas include: helpers, helpers.api, helpers.localization, json, os, subprocess, sys.

Key Concepts

  • Important called helpers/classes observed in the source: Response, plugins.find_plugin_assets, plugins.get_plugin_meta, plugins.get_default_plugin_config, plugins.save_plugin_config, plugins.toggle_plugin, plugins.find_plugin_dir, files.get_abs_path, Localization.get.now_iso, plugins.determine_plugin_asset_path, self._get_config, self._get_toggle_status, self._list_configs, self._delete_config, self._delete_plugin, self._get_default_config, self._save_config, self._toggle_plugin, self._get_doc, self._run_execute_script.
  • Keep request/response, tool, or helper semantics documented here at the same time as source changes.

Work Guidance

  • Preserve authentication, CSRF, loopback, and API-key checks unless the endpoint contract explicitly changes.
  • Update frontend callers, plugin callers, and tests together when payload shape changes.
  • Use helpers.api.Response for non-JSON responses, files, redirects, or status-specific replies.

Verification

  • Run endpoint-specific or API/WebSocket tests for changed behavior; smoke-test browser callers when no focused test exists.
  • Related tests observed by source search:
    • tests/test_a0_connector_computer_use_metadata.py
    • tests/test_a0_connector_prompt_gating.py
    • tests/test_browser_agent_regressions.py
    • tests/test_chat_compaction.py
    • tests/test_default_prompt_budget.py
    • tests/test_document_query_plugin.py
