Overview

The OpenSRE interactive shell persists every line you type to a history file so up-arrow recall and /history work across sessions, and separately records each LLM prompt/response turn for local debugging and /resume. Incident prompts can include sensitive identifiers and tokens, so the shell:
  • redacts known token shapes before each entry is written to disk
  • supports disabling persistence entirely (memory-only mode)
  • caps how many entries are kept (oldest pruned)
  • offers a one-shot /history clear to wipe the file on demand
The history file lives at ~/.opensre/interactive_history. See Prompt and response logging below for the separate LLM turn log and its PostHog forwarding behavior.

Defaults

Redaction patterns

The built-in pattern set targets token shapes that are unique enough to keep false positives on natural-language incident text very low. Each match is replaced with a labeled placeholder. Redaction applies only to persistent history. The line you typed is still passed to OpenSRE’s normal pipeline as you typed it.

Prompt and response logging

Separately from typed-command history, the interactive shell records each LLM turn — the full prompt sent and the full response received — for chat and follow-up routes. This log is richer than command history (it includes model output, not just what you typed) and is used for two purposes:
  1. Local debugging / /resume: appended as JSON Lines to ~/.opensre/prompt_log.jsonl, and folded into the session file so /resume can restore conversation context.
  2. Product analytics: forwarded to PostHog as an $ai_generation event (model, provider, latency, token counts, and the prompt/response text) so we can track usage and quality of the AI features. Investigation turns additionally include the model/provider/token usage of the investigation run and an investigation_id join key; failed turns carry structured error properties ($ai_is_error, $ai_error, error_kind). Turns handled entirely by terminal tools or slash commands report $ai_model / $ai_provider as no_conversational_agent; when a conversational reply was intended but the LLM provider failed (missing API key, model access, quota, auth), the event instead reports the attempted model (or unknown) plus an ai_error_kind bucket (not_configured, quota, auth, or provider_error).

Defaults

Environment variables

PostHog forwarding for this event additionally honors the global telemetry opt-outs: set OPENSRE_NO_TELEMETRY=1, OPENSRE_ANALYTICS_DISABLED=1, or DO_NOT_TRACK=1 to stop all PostHog traffic (including $ai_generation) without touching the local JSONL file. See Environment Variables.

Config file

Redaction here uses the same built-in pattern set as command history (see Redaction patterns above) — it catches known secret shapes, not arbitrary sensitive content. Raw incident details, hostnames, or business context in a prompt are not redacted; only credential-shaped substring patterns are.

Threat model

The history file is plain text on local disk at ~/.opensre/interactive_history, with the user’s default file permissions. Built-in redaction targets common token shapes only — it is not a substitute for proper secret handling. Treat the file as confidential and be aware:
  • A determined attacker with read access to your home directory can still read pre-existing entries written before redaction was enabled.
  • Redaction cannot detect tokens that look like normal text (for example a natural-language password). Don’t paste secrets you wouldn’t be comfortable seeing in a system log.
  • Custom redaction patterns are not yet supported in v1. If you need to redact internal token shapes, use /history off for that session and run /history clear afterwards.
The prompt/response log carries the same caveat, plus one more: with PostHog forwarding on (the default), redacted prompt/response text leaves your machine. If you discuss confidential systems or data in the interactive shell, set OPENSRE_NO_TELEMETRY=1 (or OPENSRE_PROMPT_LOG_DISABLED=1 to also stop the local file) rather than relying on redaction alone. For the strongest posture: set OPENSRE_HISTORY_ENABLED=0 and OPENSRE_NO_TELEMETRY=1, accept the loss of cross-session up-arrow recall and /resume context, and rely on the in-memory ring instead.
