## The Pi _you love_, with **batteries included**.



Originally built on [Mario Zechner](https://github.com/mariozechner)'s wonderful [Pi](https://github.com/badlogic/pi-mono), omp adds everything you're missing.



### 01 · Code execution w/ tool-calling



Most harnesses give the agent a Python sandbox and call it done. Ours runs persistent Python and a Bun worker, and either kernel can call back into the agent's own tools — read, search, task — over a loopback bridge. The agent loads a CSV with tool.read from inside Python, charts it from JavaScript, and never leaves the cell.



![omp TUI: a single eval session with `[1/2] pandas describe` (Python) printing a real DataFrame.describe() table, followed by `[2/2] top scorer` (JavaScript) running a reduce. Footer: 'Both kernels ran in one session.'](https://omp.sh/captures/eval.webp)



### 02 · LSP wired into every write



Ask for a rename and you get a rename. The call goes through workspace/willRenameFiles, so re-exports, barrel files, and aliased imports update before the file moves. Everything your IDE knows, the agent knows.



![omp TUI: `LSP references` returns five hits across three files for the symbol `formatBytes`, then `LSP rename` applies the change with edits to format.ts/report.ts/cli.ts, then a `Search formatBytes 0 matches` confirmation. Final line: 'Rename complete. Five edits across three files…'.](https://omp.sh/captures/lsp.webp)



### 03 · Drives a real debugger



A C binary segfaults: the agent attaches lldb, steps to the bad pointer, reads the frame. A Go service hangs: it attaches dlv and walks the goroutines. A Python process is wedged: debugpy, pause, inspect, evaluate. Most agents are still sprinkling print statements.



![omp TUI: a live lldb-dap session against a native binary at /tmp/omp-native/demo. Adapter=lldb-dap, Status=stopped, Frame=xorshift32, Instruction pointer 0x10000055C, Location demo.c:6:10. Debug scopes and Debug variables cards show locals (x = 57351) and the agent confirms the math: x went from 7 → 57351 (= 7 ^ (7<<13)).](https://omp.sh/clips/dap-poster.webp)

### 04 · Time-traveling stream rules



Your rules sit dormant until the model goes off-script. A regex match aborts the stream mid-token, injects the rule as a system reminder, and retries from the same point. You get course-correction without paying context tax on every turn. Injections survive compaction, so the fix sticks.



![omp TUI: agent reading src.rs and about to write Box::leak when the request aborts (red `Error: Request was aborted`), an amber `⚠ Injecting rule: box-leak` card injects the rule body `Don't reach for Box::leak in production code paths`, and the agent then course-corrects by proposing `Arc` and asking the user to confirm.](https://omp.sh/clips/ttsr-poster.webp)



_[Watch the capture ↗](https://omp.sh/clips/ttsr.mp4)_



### 05 · First-class subagents



Split a job across workers and get typed results back. task fans out into isolated worktrees, each worker runs its own tool surface, and the final yield is a schema-validated object the parent reads directly. No prose to parse, no merge conflicts between siblings, no orphaned edits.



![omp TUI showing `task` spawning two subagents `ComponentsExports` and `RoutesExports`, the constraints block requiring an IRC DM between peers, the per-subagent status cards with cost and duration, and a final Findings section listing both exports plus an honest 'IRC coordination note' about a one-sided handshake.](https://omp.sh/clips/irc-poster.webp)

### 06 · Read a pdf on arxiv, why not?



web_search chains fourteen ranked providers and hands whatever URLs it finds straight to read. Arxiv PDFs, GitHub pages, Stack Overflow threads come back as structured markdown with anchors intact — the same tool surface you use on local files. Cite, follow, quote, never lose where you came from.



![omp TUI: web_search returns 10 ranked Perplexity sources for inference-time compute scaling, the agent picks an arxiv paper, calls read https://arxiv.org/pdf/2604.10739v1, and summarizes the paper's headline result with real numbers.](https://omp.sh/clips/web-poster.webp)

### 07 · Unapologetically native. Even on Windows.



Other agents shell out to rg, grep, find, and bash. On many machines those binaries don't exist, and on the ones where they do, every call costs a fork-exec round-trip. omp links the real implementations into the process. ripgrep, glob, find: in-process. brush is the bash, with sessions that survive across calls. The same omp binary runs on macOS, Linux, and Windows — no WSL bridge.



### 08 · Code review with priorities and a verdict



Get a clear verdict on whether the change ships, with every issue ranked P0 through P3 and scored for confidence. /review spawns dedicated reviewer subagents that sweep branches, single commits, or uncommitted work in parallel. You tackle what blocks release first; nothing important hides in a wall of prose.



### 09 · Hashline: edit by content hash



Perfect edits, fewer tokens. The model points at anchors instead of retyping the lines it wants to change, so whitespace battles and string-not-found loops just stop happening. Edit a stale file and the anchors diverge — we reject the patch before it corrupts anything. Grok 4 Fast spends 61% fewer output tokens on the same work.



### 10 · GitHub is just another filesystem



Other harnesses bolt on gh_issue_view, gh_pr_view, gh_search — each with its own parameters the agent has to learn and you have to debug. We skipped that. read already handles paths; PRs are paths. One interface to teach the model, one surface to keep correct.



### 11 · Hindsight: memory the agent curates



The agent remembers your codebase between sessions. It writes facts mid-run with retain, pulls them back with recall, and compresses each session into a mental model that loads on the first turn of the next one. Project-scoped by default, so what it learns about this repo stays with this repo.



### 12 · ACP: editor-drivable agent



Run omp inside Zed and you get the same agent you drive from the terminal — reading the buffer you're actually looking at, writing through the editor's save path, spawning shells in the editor's terminal. Destructive tools pause for a permission prompt you can answer once and forget. No bridge, no plugin, no second brain to keep in sync.



### 13 · Inherits what your other tools already wrote



Every other agent ships an importer and expects you to convert. omp reads the eight formats already on disk in their native shape — Cursor MDC, Cline .clinerules, Codex AGENTS.md, Copilot applyTo, and the rest. No migration script, no YAML-to-TOML port, no "supported subset" footnotes. The config your team wrote last quarter still works tonight.



### 14 · omp commit: atomic splits, validated messages



omp reads the working tree through git-overview, git-file-diff, and git-hunk, then splits unrelated changes into atomic commits ordered by their dependencies. Cycles are rejected before anything is written. Source files score above tests, docs, and configs, so the headline commit is the one that matters. Lock files are excluded from analysis entirely.



### 15 · Read PRs. _Walk skills._ Pull JSON out of subagents.



Ten internal schemes — `pr://`, `issue://`, `agent://`, `skill://`, `rule://`, and the rest — resolve transparently inside every FS-shaped tool the agent already calls. `read pr://1428` returns the same shape as `read src/foo.ts`. `search` walks a diff like a directory. `agent:///findings.0.path` pulls a field out of a subagent's output by path.



![omp TUI reading pr://can1357/oh-my-pi/1063 and then /diff/1, showing hunk headers, added lines, and a [MODIFIED] (+12 -0) summary.](https://omp.sh/captures/pr.webp)



### 16 · Conflict resolution, made easy.



Each merge conflict becomes one URL. The agent writes `@theirs`, `@ours`, or `@base` to `conflict://N` and the file resolves cleanly. Bulk form: `conflict://*`.



![omp TUI: ✓ Read src/session.ts (⚠ 1 conflict), then ✓ Write conflict://1 · 1 line with content @theirs, then a confirmation 'Resolved.'](https://omp.sh/clips/conflict-poster.webp)



_[Watch the capture ↗](https://omp.sh/clips/conflict.mp4)_



### 17 · Preview, then accept.



`ast_edit` returns a _(proposed)_ card with the replacement count. The change is staged. The agent calls `resolve` with a reason; the TUI turns it into an **Accept** card and the disk move happens — atomic, all or nothing.



![omp TUI: ✓ AST Edit: console.log($X) (proposed) 3 replacements · 1 file, then ✓ Accept: 3 replacements in 1 file (AST Edit), followed by 'Applied 3 replacements in src/auth.ts.'](https://omp.sh/clips/codemod-poster.webp)

### 18 · Drives a _real browser_. _Or your Slack?_



Stealth's on by default, so pages see a normal user instead of a headless bot. The same API drives any Electron app in place — point it at Slack and the agent reads your DMs the way it reads the web.



![omp TUI driving the browser tool against DuckDuckGo](https://omp.sh/captures/browser.webp)



## Whatever the task needs, _it's already in the box_.



32 tools live in the same namespace as `read` and `bash`. Pin the active set with `--tools read,edit,bash,…` and the rest stay hidden but indexed — `search_tool_bm25` pulls them back in mid-session when `tools.discoveryMode` says so.



**Files & search**



- `read` — files, dirs, archives, SQLite, PDFs, notebooks, URLs, and internal `://` schemes through one path.

- `write` — create or overwrite a file, archive entry, or SQLite row.

- `edit` — hashline patches with content-hash anchors and stale-anchor recovery.

- `ast_edit` — structural rewrites previewed before apply, via ast-grep.

- `ast_grep` — structural code queries over 50+ tree-sitter grammars.

- `search` — regex over files, globs, and internal URLs.

- `find` — glob-based path lookup; reach for `search` when you need content matches.



**Runtime**



- `bash` — workspace shell, with optional PTY or background-job dispatch.

- `eval` — persistent Python and JavaScript cells with shared prelude and tool re-entry.

- `recipe` — invoke a target from a detected task runner — bun, just, make, cargo.

- `ssh` — one remote command against a configured host.



**Code intelligence**



- `lsp` — diagnostics, navigation, symbols, renames, code actions, raw requests.

- `debug` — drive a DAP session — breakpoints, stepping, threads, stack, variables.



**Coordination**



- `task` — fan out subagents in parallel, optionally workspace-isolated.

- `irc` — short prose between live agents in this process.

- `todo_write` — ordered mutations over the session todo list with phase tracking.

- `job` — wait on or cancel background jobs.

- `ask` — structured follow-up questions for interactive runs.



**Outside the box**



- `browser` — Puppeteer tabs over headless Chromium or CDP-attached apps.

- `web_search` — one query across configured providers, returning answer plus citations.

- `github` — GitHub CLI ops — repo, PR, issues, code search, Actions run-watch.

- `generate_image` — generate or edit raster images via Gemini image models.

- `inspect_image` — vision-model analysis of a local image file.

- `render_mermaid` — Mermaid source to terminal-friendly ASCII or PNG.



**Memory & state**



- `checkpoint` — mark conversation state for a later collapse-and-report.

- `rewind` — prune exploratory context, keep a concise report.

- `retain` — queue durable facts into the active Hindsight bank.

- `recall` — search the Hindsight bank for raw memories.

- `reflect` — ask Hindsight to synthesize an answer over the bank.



**Misc**



- `calc` — deterministic arithmetic — no model in the loop.

- `resolve` — apply or discard a queued preview action.

- `search_tool_bm25` — BM25 over the hidden tool index; activates top matches mid-session.



Setting-gated, off by default: `github`, `calc`, `inspect_image`, `render_mermaid`, `checkpoint`, `rewind`, `search_tool_bm25`, `retain`, `recall`, `reflect`. Flip them on once, scoped per project.

## Forty-plus providers, hundreds of models, _one /model away_.



Roles route work by intent. `default` for normal turns. `smol` for cheap subagent fan-out. `slow` for deep reasoning. `plan` for plan mode. `commit` for changelogs. Override at launch with `--smol`, `--slow`, or `--plan`; cycle through the configured models for the active role with `Ctrl+P`. Swap the active model mid-session with the `/model` slash command.



Auth tags below: `oauth` signs in with your provider account, `plan` routes through a coding-plan subscription, `local` runs against a local server with the key optional.



### Frontier APIs



Direct APIs and gateways. Mix providers per role.



Anthropic `oauth` · OpenAI · OpenAI Codex `oauth` · Google Gemini · Google Antigravity `oauth` · xAI · Mistral · Groq · Cerebras · Fireworks · Together · Hugging Face · NVIDIA · OpenRouter · Synthetic · Vercel AI Gateway · Cloudflare AI Gateway · Perplexity `oauth`



### Coding plans



Subscription-routed. `/login` attaches the session.



Cursor `oauth` · GitHub Copilot `oauth` · GitLab Duo · Kimi Code `plan` · Moonshot · MiniMax Coding Plan `plan` · MiniMax Coding Plan CN `plan` · Alibaba Coding Plan `plan` · Qwen Portal · Z.AI / GLM Coding Plan `plan` · Xiaomi MiMo · Qianfan · NanoGPT · Venice · Kilo · ZenMux · OpenCode Go · OpenCode Zen



### Run it yourself



OpenAI-compatible `/v1/models`. Local instances skip the key.



Ollama `local` · Ollama Cloud · LM Studio `local` · llama.cpp `local` · vLLM `local` · LiteLLM



### Four knobs that make routing useful



- **Custom providers** — Declare anything that speaks `openai-completions`, `openai-responses`, `openai-codex-responses`, `azure-openai-responses`, `anthropic-messages`, `google-generative-ai`, or `google-vertex` in `~/.omp/agent/models.yml`.

- **Fallback chains** — Per-role chains under `retry.fallbackChains`. When the primary throws 429s or hits a quota wall, the next entry takes the rest of the turn — restored on cooldown.

- **Path-scoped roles** — Nest `paths:` under `modelRoles` to pin a heavier `default` on one repo without touching the global config. Closest path wins.

- **Round-robin credentials** — Stack API keys per provider and the runtime rotates with session affinity and per-credential backoff. Useful when one key would burn its quota by lunch.



Full provider & routing reference at [omp.sh/docs/providers](https://omp.sh/docs/providers).



## Fourteen backends. _One tool the agent already knows_.



`web_search` is built in, not bolted on. `auto` walks a fourteen-provider chain; pin one by name if you already pay for it. Behind every hit, site-aware extraction turns GitHub, registries, arXiv, Stack Overflow, and docs into structured markdown — anchors and link targets survive.



### Search providers



Fourteen backends. Pin one, or let `auto` walk the chain in order.



| provider     | auth                   |

| ------------ | ---------------------- |

| `auto`       | chain                  |

| `exa`        | `EXA_API_KEY` (or mcp) |

| `brave`      | `BRAVE_API_KEY`        |

| `jina`       | `JINA_API_KEY`         |

| `kimi`       | `MOONSHOT_API_KEY`     |

| `zai`        | `ZAI_API_KEY`          |

| `anthropic`  | oauth                  |

| `perplexity` | `PERPLEXITY_API_KEY`   |

| `gemini`     | oauth                  |

| `codex`      | oauth                  |

| `tavily`     | `TAVILY_API_KEY`       |

| `parallel`   | `PARALLEL_API_KEY`     |

| `kagi`       | `KAGI_API_KEY`         |

| `synthetic`  | `SYNTHETIC_API_KEY`    |

| `searxng`    | self-hosted            |



### Specialised handlers



The agent gets structured content, not stripped HTML.



- **Code hosts** — github, gitlab

- **Package registries** — npm, PyPI, crates.io, Hex, Hackage, NuGet, Maven, RubyGems, Packagist, pub.dev, Go packages

- **Research sources** — arxiv, semantic scholar

- **Forums** — stack overflow, reddit, hn

- **Docs** — mdn, readthedocs, docs.rs



Pages convert to markdown with link structure intact. The agent can cite, follow, and quote without losing anchors.



### Security databases



Vuln lookups answer with vendor data, not blog summaries.



- **NVD** — national vulnerability database

- **OSV** — open source vuln feed

- **CISA KEV** — known exploited vulns



[`web_search` reference ↗](https://omp.sh/docs/tools#web_search)



## Roughly **~27,000** lines of Rust, doing the work other harnesses shell out for.



Three crates, one platform-tagged N-API addon. Search, shell, AST, highlight, PTY, image decode, BPE counting — all in-process on the libuv pool. No fork/exec on the hot path.



- Crates: `pi-natives`, `pi-shell`, `pi-ast`

- Platforms: `linux-x64`, `linux-arm64`, `darwin-x64`, `darwin-arm64`, `win32-x64`

## Four entry points: _interactive_, _one-shot_, RPC, and ACP.



Same engine, four wrappers. `omp` runs the TUI. `omp -p` answers a single prompt and exits. The Node SDK embeds the session in your process. `omp --mode rpc` and `omp acp` hand the wheel to another program over stdio.



### Interactive — when in doubt, the agent asks



The TUI is the default surface. Tool calls render as cards, edits preview before they land, and ambiguity routes through the `ask` tool — a structured option picker the agent can call mid-turn. The keyboard handles the rest.



The same prompt cards surface over ACP, so editors get the picker without writing one.



![omp TUI: the ask tool renders an option picker with three choices, a (Recommended) badge on the first, and 'up/down navigate · enter select · esc cancel' footer.](https://omp.sh/captures/ask.webp)



### SDK — embed in Node



`@oh-my-pi/pi-coding-agent`



Node and TypeScript hosts pull the engine in directly. The package exposes `ModelRegistry`, `SessionManager`, `createAgentSession`, and `discoverAuthStorage`; the session emits typed events you subscribe to.



```ts

import { ModelRegistry, SessionManager, createAgentSession, discoverAuthStorage } from "@oh-my-pi/pi-coding-agent";



const auth = await discoverAuthStorage();

const models = new ModelRegistry(auth);

await models.refresh();



const { session } = await createAgentSession({

	sessionManager: SessionManager.inMemory(),

	authStorage: auth,

	modelRegistry: models,

});

await session.prompt("list .ts files");

```



### RPC — drive over stdio



`omp --mode rpc`



For non-Node embedders, or when you want process isolation. NDJSON commands in, response and event frames out. `--mode rpc-ui` adds tool cards, selectors, and dialogs as `extension_ui_request` frames the host must answer.



```

$ omp --mode rpc --no-session

> {"id":"r1","type":"prompt","message":"list .ts files"}

< {"id":"r1","type":"response", ...}

> {"id":"r2","type":"set_model","provider":"anthropic","modelId":"sonnet-4.5"}

> {"id":"r3","type":"abort"}

```



### ACP — speak to editors



`omp acp`



The [Agent Client Protocol](https://github.com/zed-industries/agent-client-protocol) over JSON-RPC. When the editor advertises capabilities, tool I/O routes through it and writes are gated by `session/request_permission`.



| omp tool                      | ACP route                           |

| ----------------------------- | ----------------------------------- |

| `bash`                        | `terminal/create + terminal/output` |

| `read`                        | `fs/read_text_file`                 |

| `write`                       | `fs/write_text_file`                |

| `edit, ast_edit, write, bash` | `session/request_permission`        |

## A harness worth keeping is one you _don't_ outgrow.



Pick it up at **[omp.sh](https://omp.sh)**.



omp is a fork of [Pi](https://github.com/badlogic/pi-mono) by [Mario Zechner](https://github.com/mariozechner), rewritten as a coding-first surface: sessions, subagents, slash commands, extensions — all TypeScript, all MIT, all on [GitHub](https://github.com/can1357/oh-my-pi). Shape it from config, hook it from outside, or read the source when you need to.



### Primitives



An extension is a TypeScript module. Same tool API, same slash-command registry, same hotkey table, same TUI primitives the built-ins use. Nothing is reserved.



### Discovery



On first run omp inherits whatever is already on disk: rules, skills, and MCP servers from `.claude`, `.cursor`, `.windsurf`, `.gemini`, `.codex`, `.cline`, `.github/copilot`, and `.vscode`. No migration script.



### Extensibility



Ask omp to write the piece you're missing, then `/reload-plugins`. Keep it local, ship it in a `marketplace`, or publish it to npm.



## Philosophy



omp is a fork of [pi-mono](https://github.com/badlogic/pi-mono) by [Mario Zechner](https://github.com/mariozechner), extended with a batteries-included coding workflow.



Key ideas:



- Keep interactive terminal-first UX for real coding work

- Include practical built-ins (tools, sessions, branching, subagents, extensibility)

- Make advanced behavior configurable rather than hidden
