Install the Ultrawork skill

Skills CLI (Claude Code, Codex, Cursor and others)

npx skills add https://github.com/code-yeongyu/oh-my-openagent --skill ultrawork

Claude Code, by hand (all projects)

git clone --depth 1 https://github.com/code-yeongyu/oh-my-openagent.git /tmp/oh-my-openagent
mkdir -p ~/.claude/skills
cp -R /tmp/oh-my-openagent/packages/omo-senpi/skills/ultrawork ~/.claude/skills/ultrawork

For one project only, copy the folder into .claude/skills/ in that project instead. The agent picks it up when a task matches its description.

What it costs your context

Agent Skills load in three steps. Tokens counted with the o200k tokenizer; your model's count will differ a little.

Until it is used, ultrawork costs about 35× less than the median MCP server we measured (1,362 tokens on every turn). Installing all 60 skills from code-yeongyu/oh-my-openagent would load 5,128 tokens of descriptions. Skills vs MCP study

  • Role
  • Goal
  • Tier triage (classify ONCE at bootstrap; record tier + one-line
  • Manual-QA channels
  • Bootstrap (COMPLETE EVERY SECTION BEFORE ANY OTHER WORK — NO SKIPPING)
  • Task resources
  • 0. Survey the skills, gather context, then size the work
  • 1. Create the goal with binding success criteria
  • 2. Open the durable notepad
  • 3. Write the plan to a file, then register obsessive todos via todo
  • Finding things (lead with these, code-mode the first wave)
  • Parallel execution (batch what is independent, observe what is not)
  • Execution loop (READ → CHANGE → RUN → CLEAN)
  • Waiting discipline (subscribe, never sleep)
  • omo-senpi task + team tools
  • Child execution and transitions
  • Verification gate (TRIGGERED, NOT OPTIONAL)
  • Commits
  • Constraints
  • Output discipline
  • Stop rules

  1. ast-grepcode-yeongyu/oh-my-openagent

    Searches and rewrites code by AST shape across 25 languages. Use when the target is a syntax pattern (every call/class/import shaped like X, a codemod, a YAML rule) rather than literal text; for plain strings, comments, or filenames, use rg.

  2. browsercode-yeongyu/oh-my-openagent

    Drives a real browser through the omowright library from the js eval kernel: sites the user is already signed into, forms and clicks, JS-rendered pages, screenshots, web QA, extension popups, a human handoff for login, CAPTCHA or OTP, and a browser you own for scraping, bot-scored targets, network capture and QA traces. Use for any interactive browser task; not for a plain search or an unblocked static fetch.

  3. codex-qacode-yeongyu/oh-my-openagent

    QA the omo Codex Light edition (lazycodex / packages/omo-codex) itself, in strict isolation so ONLY our plugin is exercised, never the user's real ~/.codex. The first-party method drives the real `codex app-server` against an isolated CODEX_HOME plus a LOCAL mock model (no real API call), and proves a plugin hook fired by asserting hook/started + hook/completed notifications. Also: isolated install verification, per-component hook probes, a tmux TUI smoke, and runtime log observation (RUST_LOG / logs SQLite / /debug-config). Ships tested helper scripts each with a --self-test. Use whenever someone changes anything under packages/omo-codex or wants to QA, smoke-test, verify, or debug the Codex plugin, its hooks/components, the installer/config.toml, the app-server flow, or the Codex TUI. Triggers: codex qa, qa codex, codex-qa, test codex plugin, verify codex hook, codex app-server, lazycodex qa, isolated CODEX_HOME, prove codex hook fired, codex tui test.

  4. coding-agent-sessionscode-yeongyu/oh-my-openagent

    Finds, reads, and reconstructs coding-agent sessions across Codex, Claude, OpenCode, OMO/Senpi, and other local agent logs. Use when asked to find or search past sessions, transcripts, or subagent runs, or to recover what an earlier session did.

  5. comment-checkercode-yeongyu/oh-my-openagent

    Use when Codex needs to understand or respond to automatic comment-checker feedback emitted after an edit-like PostToolUse hook.

  6. dag-librarycode-yeongyu/oh-my-openagent

    Stores a DAG definition once and re-runs it by name, instead of pasting the definition into every run. Use when the user wants to save a DAG, run a saved one, or schedule the same multi-agent graph repeatedly.

  7. data-scientistcode-yeongyu/oh-my-openagent

    Processes and analyzes data with resident-kernel engines (DuckDB, Polars) and one-shot tools. Use for CSV/parquet/JSON analysis, group-by/join/aggregation, time series, distributions, cleaning, or plotting a dataset.

  8. debuggingcode-yeongyu/oh-my-openagent

    Runs a hypothesis-driven debugging loop across any language or binary, escalating to orthogonal oracle angles and locking the fix with a failing test. Use for crashes, silent failures, hangs, wrong responses, memory leaks, async misbehavior, or reverse engineering.
