Project overview
oh-my-pi (omp) is a terminal AI coding agent that positions itself as 'a coding agent with the IDE wired in.' Unlike browser-based assistants or editor plugins, omp runs as a standalone TUI built on a Rust core of approximately 80,000 lines, surfaced to the user through a TypeScript/Bun application layer. The project is a fork of Pi by Mario Zechner (@mariozechner), with significant additional engineering by Can Bölük (@can1357).
The headline numbers are aggressive: 60+ model providers, 31 built-in tools, 14 LSP operations, and 28 DAP (Debug Adapter Protocol) operations. These are not just marketing claims — the DAP integration is visible in the README's visual assets, showing a live lldb-dap session against a native binary with stopped status, frame inspection, instruction pointer, and local variable resolution. This is deeper than what most terminal agents offer.
omp differentiates on three axes. First, hash-anchored edits: file modifications are tied to content hashes so the agent detects conflicts before writing, surfacing them through a conflict:// URI scheme the user resolves inline. Second, the tool harness is described as 'benchmaxxed' — reads summarize rather than dump, searches return instantly, and edits are tuned to land on the first attempt. Third, the agent has a rule-injection system that can intercept mid-generation requests and course-correct; the README shows an example where proposing Box::leak in Rust triggers an injected 'box-leak' rule that steers the agent toward Arc<str> instead.
Why it is trending now
- 355 stars in the trending period with rank 12, driven by the combination of Rust-core performance and terminal-native UX
- Forks an already-known project (Pi) but adds a substantial Rust core, DAP debugging, LSP integration, and browser tools that go far beyond the original
- The install story is frictionless: curl pipe sh, Homebrew, Bun global install, mise pinning, and a Windows PowerShell installer all ship from day one
- Shell completions are generated from live command/flag metadata for bash, zsh, and fish — they never drift from the actual CLI surface
- 60+ provider support means users are not locked into a single API vendor; the catalog spans OpenAI, Anthropic, and others
Problem it solves
- Terminal coding agents typically lack IDE-grade introspection — no LSP symbol awareness, no debugger integration, no structured file conflict handling
- Most agent edit systems overwrite blindly or require full-file rewrites, causing merge conflicts and lost context on large files
- Multi-provider setups usually mean maintaining separate configs per vendor; omp bundles a model catalog that resolves --model, --smol, --slow, and --plan flags against a unified registry
- Alpine/musl users face a known gap: the prebuilt musl binary dynamically links libstdc++ and libgcc, which stock Alpine does not ship — the README documents apk add libstdc++ libgcc as the fix
How it works
- Install via bun install -g @oh-my-pi/pi-coding-agent (recommended), or curl -fsSL https://omp.sh/install | sh on macOS/Linux, or irm https://omp.sh/install.ps1 | iex on Windows. Requires Bun >= 1.3.14.
- The TUI launches as omp, presenting a terminal interface where the agent reads files, performs edits, runs tools, and interacts with LSP/DAP sessions.
- When the agent edits a file, it computes a content hash anchor. If the file changed between read and write, omp surfaces a conflict:// URI with markers like @theirs, and the user resolves inline before the write completes.
- For debugging, omp connects through DAP adapters (e.g., lldb-dap), exposing 28 operations: breakpoints, frame inspection, variable evaluation, step control, and scope browsing — all rendered in the TUI.
- For web research, the agent calls web_search (backed by Perplexity), reads returned URLs including direct PDF fetching from arxiv, and summarizes findings with quantitative results.
- Rule injection monitors agent output in real time; when a pattern matches (e.g., Box::leak in Rust production code), the agent's request is aborted and a rule body is injected, forcing course correction before the user sees the bad output.
Product demo and interface preview
Architecture: Rust Core, Bun Surface, napi-rs Bridge
The Cargo.toml workspace declares members under crates/pi-* and crates/vendor/*, with version 17.2.9 and Rust edition 2024. The release profile uses opt-level 3, fat LTO, codegen-units 1, and strip — production-grade settings that prioritize binary size and runtime performance over compile speed.
Crash resilience is engineered explicitly. The panic strategy is set to unwind (not abort) so panics inside vendored code and native tasks stay recoverable. The uutils boundary (pi-shell coreutils) turns a panic into a failed command rather than a process crash. The task::blocking wrapper in crates/pi-natives/src/task.rs catches unwinds inside Blocking::compute before they cross napi-rs's async-work extern 'C' callback, surfacing as rejected JS Promises instead of forced process aborts under Rust's C-unwind rules (RFC 2945, stable since 1.81).
The package.json reveals a monorepo with packages under packages/* and python/robomp/web. Patched dependencies include @ark/schema, puppeteer-core, and @agentclientprotocol/sdk — indicating the team maintains local patches against upstream packages for browser automation and agent protocol conformance. OpenTelemetry is wired in for traces, metrics, and logs with OTLP proto exporters, giving observability into agent sessions.
Command Surface and Shell Integration
- omp completions zsh / bash / fish generates completion scripts from live CLI metadata — subcommands, flags, enum values complete statically
- Model flags --model, --smol, --slow, --plan resolve against the bundled model catalog
- --resume resolves against on-disk sessions for continuing prior conversations
- bun check runs the full type-check and lint suite expected in contributions
- Dev mode: bun --cwd=packages/coding-agent src/cli.ts launches from source without a global install
Fastest Path to Try It
Install with bun install -g @oh-my-pi/pi-coding-agent on any platform with Bun >= 1.3.14. Alternatively, brew install can1357/tap/omp on macOS, or curl -fsSL https://omp.sh/install | sh on Linux. On Alpine, run apk add libstdc++ libgcc first.
Launch omp in any repository directory. Point it at a task — 'find the bug in the xorshift32 function' or 'add error handling to this endpoint.' Watch the hash-anchored edit flow: the agent reads with summaries, proposes edits with content hashes, and surfaces conflicts inline if the file changed. Try the DAP integration by asking it to debug a native binary — the TUI will show the lldb-dap adapter, stopped status, frame, and local variables.
To test rule injection, ask it to write production Rust code that might reach for Box::leak. The agent should abort and inject the box-leak rule, then propose Arc<str> as an alternative, asking for confirmation before proceeding.
Maintenance Risk: Solo Maintainer, Trial PR Policy
The CONTRIBUTING.md states PRs are 'temporarily open to everyone' as a trial. Previously, the project required a vouch before accepting PRs. The document explicitly notes: 'Depending on the results, the vouch system may return.' This signals a project still calibrating its contribution model.
Major changes require Discord discussion before implementation — a GitHub issue is explicitly not a substitute. The project uses robomp (its own AI agent) to pick up actionable issues, which means filing an issue for work you intend to do yourself risks parallel implementation. Contributors are told: do not create an issue first if you plan to submit a PR.
The project is MIT licensed (Copyright Mario Zechner 2025, Can Bölük 2025-2026). The version is at 17.2.9, suggesting rapid iteration — this is not a v1 project but one with substantial revision history behind it.
Who should pay attention?
Good fit if
- You live in the terminal and want an agent that understands LSP symbols, DAP debug sessions, and file conflicts without launching an IDE
- You need multi-provider flexibility — 60+ providers means you can switch between OpenAI, Anthropic, and others without reconfiguring
- You work with native binaries (C, Rust) and want the agent to actually debug them through lldb-dap rather than just read source
- You want hash-anchored edit safety where the agent refuses to blindly overwrite files that changed between read and write
Skip for now if
- You need a stable, long-term-supported tool with a large maintainer team — omp is primarily driven by Can Bölük with trial-period contribution policy
- You want a GUI/IDE extension experience — omp is a TUI application with no editor plugin surface
- You are on Alpine/musl and cannot install libstdc++ and libgcc — the prebuilt binary requires them
Risks and cautions
Technically impressive with a Rust core and deep tooling, but the solo-maintainer model and trial PR policy create uncertainty about long-term contribution sustainability.
- Primarily maintained by Can Bölük; PR policy is explicitly temporary and may revert to a vouch system
- Version 17.2.9 indicates rapid iteration — breaking changes between versions are possible
- The project patches three upstream dependencies (@ark/schema, puppeteer-core, @agentclientprotocol/sdk) which must track upstream releases
- Alpine/musl binary has a known runtime dependency gap requiring manual package installation
- MIT licensed with clear copyright attribution to Mario Zechner and Can Bölük
- Rule injection system acts as a runtime guardrail — the box-leak rule demonstrates that agent proposals can be intercepted and corrected before reaching the user
- Hash-anchored edits prevent silent overwrites; conflicts are surfaced as conflict:// URIs requiring explicit resolution
- The CONTRIBUTING.md requires human-authored explanation in every PR body and explicitly rejects unreviewed agent-generated output, reducing supply-chain risk from AI-generated contributions
- Browser automation uses puppeteer-core (patched locally), and web_search goes through Perplexity — no undocumented network surface

What this trend reveals
DAP Integration as a Differentiator
28 DAP operations in a terminal agent is rare. Developers working with native code (C, C++, Rust) can have the agent set breakpoints, inspect frames, and read locals without leaving the terminal or switching to a separate debugger.
The DAP poster visual shows a live lldb-dap session with stopped status, frame=xorshift32, instruction pointer 0x10000055C, and local variable x=57351 — demonstrating the integration works end to end.
Hash-Anchored Edit Safety for CI/CD
The conflict:// URI scheme and content-hash anchoring could be valuable in automated pipelines where agents edit files without human supervision — conflicts are detected mechanically, not heuristically.
The conflict poster visual shows the flow: read with conflict detection, write via conflict://1 with @theirs marker, and explicit 'Resolved' confirmation.
Rule Injection for Compliance-Gated Code
The real-time rule injection system (demonstrated with the box-leak rule) can be extended to enforce organization-specific coding standards — banned APIs, required error handling patterns, or security-sensitive function restrictions.
The ttsr poster visual shows the agent's request being aborted (red Error: Request was aborted) with an amber rule-injection card for the box-leak rule, followed by the agent proposing Arc<str> and asking for confirmation.
RepoDaily verdict
oh-my-pi is the most technically ambitious terminal coding agent available: ~80k lines of Rust core, 28 DAP operations, 14 LSP operations, hash-anchored edits, real-time rule injection, and 60+ provider support. The risk is a solo maintainer with a trial PR policy. For developers who want IDE-grade introspection in the terminal and can tolerate version churn, it is worth the 30-minute evaluation.
