⌥ AI Coding agent for the terminal — hash-anchored edits, optimized tool harness, LSP, Python, browser, subagents, and more
omp is a terminal-first coding agent that runs on your machine, talks to any provider, and treats sessions like git branches.
omp (pronounced “oh-em-pi”, binary omp) is a fork of Mario Zechner’s Pi. It runs as a single Bun process, drives any model provider you have credentials for, and ships a flat tool surface the model uses to read code, run commands, edit files, drive a debugger, and spawn subagents that coordinate over an in-process IRC bus.
Sessions persist as JSONL under ~/.omp/agent/sessions/. You resume, fork, branch, and share them. Settings, credentials, plugins, and caches all live under ~/.omp/agent/. Nothing leaves the machine unless you call a tool that does.
Fixed an HTTP 400 error when resuming or replaying OpenAI history after an interrupted native Computer Use turn.
Fixed connection 404 errors when using Google Vertex AI in multi-region locations (eu and us) by correctly resolving regional endpoint (REP) hosts.
Fixed a resource leak in SqliteAuthCredentialStore.close() where unclosed prepared statements kept the SQLite connection alive, preventing database file cleanup (especially on Windows where files remained locked).
@oh-my-pi/pi-catalog
Added
Added resolveVertexEndpointHost(location) utility to resolve the correct Vertex AI API endpoint hostnames for global, multi-region, and regional locations.
Fixed
Fixed an issue where calculateCost under-reported Anthropic cache-write costs by honoring the usage.cttl breakdown to correctly price 1-hour retention writes at 2x the base input rate.
@oh-my-pi/pi-coding-agent
Breaking Changes
Changed tab.screenshot() to no longer accept a per-call save path; it now saves screenshots under browser.screenshotDir (or the OS temp directory if unset) and returns the saved path.
Added
Added omp cleanse, a new command that automatically detects language-ecosystem checkers, parses diagnostics (such as Cargo Clippy JSON), distributes repair workloads across concurrent subagents, and runs verification checks with a live progress bar.
Changed
Reworked the /guided-goal command from a modal-based popup flow into a natural, conversational chat interface where the agent asks follow-up questions directly in the session.
Reduced startup memory usage by lazy-loading HTML session export assets only on their first use.
Fixed
Fixed Advisor notes appending stale-review-window warnings when newer primary turns are queued during a review.
Fixed layout padding alignment issues in bordered output blocks and web-search result panels.
Fixed excluded web search providers remaining visible in the Web Search Provider Order settings list.
Fixed internal Hub peer messages being exposed as ordinary tool-call updates in clients like Paseo.
Fixed compatibility issues when installing legacy pi extensions by updating the legacy shim to correctly bridge missing runtime symbols and exports (such as isContextOverflow, isRetryableAssistantError, and JSON parsing utilities).
Fixed an issue where routine daemon operations (like list, logs, stop, or describe) could inadvertently trigger a restart loop for detached daemons in a backoff window.
Fixed marketplace plugin MCP discovery to correctly honor the mcpServers manifest field in plugin configuration files.
Fixed user-initiated shell executions (! and $) being misattributed as agent actions in advisor transcripts.
Fixed unnecessary prompt-cache invalidations by preserving the active auto-thinking effort level when per-turn classification fails.
Fixed the omp process name showing up as bun in Linux process managers (like ps and top).
Fixed agent shell commands inheriting environment variables from the launch directory's .env file, ensuring they only receive the parent environment and explicit tool overrides.
Fixed the /new command retaining completed or failed async jobs from the previous session.
Improved error handling in omp update to display a friendly timeout message if the download times out while streaming the binary.
Fixed the write tool incorrectly treating semicolon-joined read selectors as filesystem paths and creating unintended directory structures.
Fixed omp worktree clear prematurely deleting active task-isolation sandboxes owned by running subagents.
Fixed /vibe mode preventing the director from completing parent tasks after verifying worker results by keeping the built-in todo tool active.
Fixed numeric GitHub issue and pull request autocomplete being suppressed inside skill slash-command arguments.
@oh-my-pi/pi-natives
Fixed
Fixed an issue on macOS (darwin) where the native addon delivered zero AudioCapture callbacks, which prevented microphone audio from being captured.
@oh-my-pi/pi-tui
Fixed
Fixed wrapped Markdown list continuations losing their hanging indentation in narrow terminal layouts.
Fixed an issue where emergency exits from fullscreen overlays could leave the Kitty keyboard protocol active, corrupting Arrow Up input in the terminal after exiting.
@oh-my-pi/pi-utils
Added
Added setProcessName utility to set the OS-visible process name on Linux via bun:ffi, bypassing Bun's process.title limitations.
Fixed
Fixed child shell environment filtering to drop launch-directory .env values in addition to Bun-autoloaded .env.local values.
