For an empty result, authentication failure, version mismatch, unavailable -Server, or invalid response, the hook writes one diagnostic JSON line to stderr. +Server, or invalid response, the hook returns one content-free diagnostic JSON event through the top-level +`systemMessage` in its successful stdout response. If context is available, `hookSpecificOutput` is returned beside +the diagnostic. Repeated failures are deduplicated per invocation and throttled for 60 seconds across hook processes. Diagnostics contain status and byte counts only—never the query, scope, content, citation, response body, or authorization value. diff --git a/integrations/codex/plugins/powercontext/hooks/diagnostics.py b/integrations/codex/plugins/powercontext/hooks/diagnostics.py new file mode 100644 index 000000000..782090f2f --- /dev/null +++ b/integrations/codex/plugins/powercontext/hooks/diagnostics.py @@ -0,0 +1,103 @@ +# Copyright (c) 2026 OceanBase. +# +# Licensed under the Apache License, Version 2.0 (the "License"); +# you may not use this file except in compliance with the License. +# You may obtain a copy of the License at +# +# http://www.apache.org/licenses/LICENSE-2.0 +# +# Unless required by applicable law or agreed to in writing, software +# distributed under the License is distributed on an "AS IS" BASIS, +# WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or implied. +# See the License for the specific language governing permissions and +# limitations under the License. + +"""Best-effort cross-process throttling for host-visible hook diagnostics.""" + +from __future__ import annotations + +import json +import os +import time +from collections.abc import Iterator +from contextlib import contextmanager +from pathlib import Path + +_FAILURE_OUTCOMES = frozenset({"authentication_failed", "version_mismatch", "server_unavailable", "invalid_response"}) +_COOLDOWN_SECONDS = 60.0 + + +def _state_path() -> Path: + configured = os.environ.get("POWERCONTEXT_DIAGNOSTIC_STATE_FILE") + if configured and configured.strip(): + return Path(configured) + if os.name == "nt": + root = Path(os.environ.get("LOCALAPPDATA") or Path.home() / "AppData" / "Local") + else: + root = Path(os.environ.get("XDG_STATE_HOME") or Path.home() / ".local" / "state") + return root / "powercontext" / "codex-diagnostics.json" + + +@contextmanager +def _locked(lock_path: Path) -> Iterator[None]: + lock_path.parent.mkdir(parents=True, exist_ok=True) + with lock_path.open("a+b") as lock_file: + if os.name == "nt": + import msvcrt + + lock_file.seek(0, os.SEEK_END) + if lock_file.tell() == 0: + lock_file.write(b"\0") + lock_file.flush() + lock_file.seek(0) + msvcrt.locking(lock_file.fileno(), msvcrt.LK_NBLCK, 1) + else: + import fcntl + + fcntl.flock(lock_file.fileno(), fcntl.LOCK_EX | fcntl.LOCK_NB) + try: + yield + finally: + if os.name == "nt": + import msvcrt + + lock_file.seek(0) + msvcrt.locking(lock_file.fileno(), msvcrt.LK_UNLCK, 1) + else: + import fcntl + + fcntl.flock(lock_file.fileno(), fcntl.LOCK_UN) + + +def should_emit(outcome: str) -> bool: + """Return whether a diagnostic should be shown to the host user.""" + + if outcome not in _FAILURE_OUTCOMES: + return True + + try: + now = time.time() + state_path = _state_path() + with _locked(state_path.with_name(f"{state_path.name}.lock")): + try: + state = json.loads(state_path.read_text(encoding="utf-8")) + except (FileNotFoundError, OSError, UnicodeDecodeError, json.JSONDecodeError): + state = {} + if not isinstance(state, dict): + state = {} + previous = state.get(outcome) + if ( + isinstance(previous, (int, float)) + and not isinstance(previous, bool) + and 0 <= now -
