Install the Coding Agent Sessions skill

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

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

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/shared-skills/skills/coding-agent-sessions ~/.claude/skills/coding-agent-sessions

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.

Until it is used, coding-agent-sessions costs about 22× 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

  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.

  5. 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.

  6. 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.

  7. 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.

  8. dev-browsercode-yeongyu/oh-my-openagent

    Browser automation with persistent page state. Use when users ask to navigate websites, fill forms, take screenshots, extract web data, test web apps, or automate browser workflows. Trigger phrases include "go to [url]", "click on", "fill out the form", "take a screenshot", "scrape", "automate", "test the website", "log into", or any browser interaction request.
