postmortemthis is an open-source command-line agent harness and orchestration tool developed by Softeria. It orchestrates specialized CLI coding agents and models to perform automated codebase analysis, failure diagnosis, and postmortem investigations. Operating directly in the terminal, postmortemthis coordinates underlying agent engines—such as xAI's Grok Build (@xai-official/grok), Claude, Antigravity, and OpenRouter-compatible models. It handles agent bootstrapping and runtime isolation, passing non-interactive, read-only flags (such as permission bypass and dontAsk modes) to subordinate CLI binaries to safely inspect logs, repo state, and diffs without interactive prompts. Unlike general-purpose coding assistants aimed at interactive pair-programming and feature generation, postmortemthis serves as a targeted runner for incident reviews and diagnostic sweeps. It abstracts tool bootstrapping via the gg runner ecosystem and automatically routes between native provider keys and OpenRouter endpoints based on backend capabilities. postmortemthis is open source and hosted on GitHub. Model usage and execution costs are dependent on the user's configured provider credentials (e.g., OpenRouter or xAI API keys).
