# Features

> What OpenSRE can do today

## Investigation workflow

OpenSRE runs a structured RCA pipeline for each alert:

1. **Extract context** from the alert payload and connected integrations
2. **Plan evidence collection** across logs, metrics, deploys, and dependencies
3. **Test hypotheses** in a tool-calling loop until confidence is high enough to stop
4. **Publish findings** as `problem.md`, `theory/hypothesis_*.md`, and `report.md` (or JSON with `--output`)

Run investigations from the interactive shell (`opensre`) or one-shot via `opensre investigate -i <alert-file>`. See [Investigations overview](/investigation-overview).

## Integrations (60+ tools)

Connect observability, cloud, databases, incident management, messaging, and workflow systems so investigations can query the same tools your engineers use. Setup via `opensre onboard`, `opensre integrations setup`, or environment variables. See [Integrations overview](/integrations-overview).

## Interactive shell

The TTY REPL (`opensre` with no subcommand) supports:

* Plain-language incident descriptions and follow-up questions
* Slash commands for health checks, investigations, integrations, remote agents, and more (`/help`)
* [Session history](/sessions) with `/sessions`, `/resume`, and `/new`
* [Local agent fleet](/fleet) monitoring for Claude Code, Cursor, Codex, and other coding agents
* [Scheduled deliveries](/cron) and [Hermes log watch](/hermes)

## Masking and safe sharing

Reversible masking replaces sensitive infrastructure identifiers (pods, clusters, hostnames, account IDs) with stable placeholders before external LLM calls, then restores originals in user-facing output. See [Masking](/masking).

Command-history redaction and persistence controls live under [Interactive Shell Privacy](/interactive-shell-privacy).

## Remote runtime investigations

Investigate deployed OpenSRE services by name — OpenSRE gathers live deployment status, recent logs, and health probes, then runs the standard RCA pipeline. See [Remote runtime investigation](/remote-runtime-investigation).
