CLAUDE CODE

CODEX

Native plugin delivery

The Codex manifest exposes the same source through Codex-native skills, with optional custom-agent adapters where the plugin publishes an agent.

check-version

Compare the installed core version against GitHub to confirm skill and agent definitions are current.

hammertime skill icon
by bOpen

hammertime

This skill should be used when the user mentions a behavioral rule they want enforced, says "always do X", "never do Y", "stop doing Z", "from now on", asks about HammerTime rules, wants to create a stop hook rule, mentions behavioral guardrails, or wants to understand how the HammerTime stop hook system works. Teaches how to write rules for the HammerTime stop hook system.

This skill should be used when the user wants to plan a project, feature, or bug fix using Linear as the agent control plane. Use when the user says "plan this in Linear", "create Linear tickets", "break this down into tasks", "push to Linear", "set up our board for this feature", or wants to turn a description or spec into well-structured, agent-ready Linear issues. Requires the official Linear MCP server to be configured.

reinforce-skills skill icon
by bOpen

reinforce-skills

Inject compressed SKILL-MAP and AGENT-MAP directive blocks into CLAUDE.md so skill names and agent IDs survive a long session. Use when modifying a CLAUDE.md, when adding a skill or agent to a plugin, or for "update the skill map", "register this agent", "skills keep getting forgotten", "sync skills to CLAUDE.md".

authored
remind skill icon
by bOpen

remind

Search and recall previous Claude Code sessions. Use for "remember when we...", "what did we do about...", "find that conversation where...", "when did I last work on...", "what was that command we used for...", or any reference to prior work absent from the current session, including vague ones like "that thing we did last week".

authored
runtime-context skill icon
by bOpen

runtime-context

This skill should be used when the user asks "what runtime am I in", "detect the execution environment", "adapt behavior for Claude Code vs a hosted bot", or "check what tools are available in this environment". Detects the current agent execution environment (Claude Code, Vercel Sandbox, or local dev) and adapts behavior accordingly — for agents or bots that run in Claude Code as subagents AND as hosted bots, or a SOUL.md/SKILL.md that must work across runtimes.

authored
setup skill icon
by bOpen

setup

Audit which bOpen plugins, CLIs, env keys, third-party skills, agents, and hooks are installed across the harness, then emit a runtime-tailored instruction plan; it installs nothing itself. Use for "bopen setup", "setup ui", "harness install", "audit my setup", "install everything", or "unified installer". For a single hook, use hook-manager.

authored
visual-wayfinder skill icon
by bOpen

visual-wayfinder

Generate a navigable visual map of a codebase or system for orientation. Use when the user asks to "map this codebase", "show me how this fits together", "give me a tour", or needs a visual orientation artifact before working in unfamiliar code.
