Two-layer redaction at the persistence boundary so credentials never reach
state.db, session_*.json, or compression:
1. agent/chat_completion_helpers.py :: build_assistant_message
- Redact assistant content before the message dict is constructed
(catches PATs / API keys the model inlines into natural language)
- Redact tool_call.function.arguments at the same site (catches secrets
inlined into tool args, e.g. terminal command=curl -H 'Authorization: ...')
Tool execution uses the raw API response object, not this dict, so
redacting the persisted shape is safe.
2. run_agent.py :: _save_session_log
- Add _redact_message_content() static helper that handles both string
content and OpenAI/Anthropic multimodal list-of-parts (image parts
pass through untouched, only text/content fields are redacted)
- Apply to every message + the cached system prompt before writing
session_*.json
Both layers respect HERMES_REDACT_SECRETS via redact_sensitive_text —
no-op when disabled.
Tests (TestSaveSessionLogRedactsSecrets, 4 cases):
- api key in tool content
- api key in user message
- api key in system prompt
- multimodal list-of-parts (image part preserved, text redacted)
Tests use an autouse fixture to force _REDACT_ENABLED=True because the
hermetic conftest defaults the env var to false.
Salvaged from PR #24758 by @vgocoder (build_assistant_message + session_log)
+ PR #19855 by @liuhao1024 (multimodal list helper, system_prompt redaction).
Kept only the redaction concern from #19855; its unrelated whatsapp npm
timeout + PATCH_SCHEMA changes are out of scope and dropped.
Refs #19798 (PAT leak via assistant inline mention), #19845 (session capture
credential leak).
