auth-md

Implement or review the experimental WorkOS auth.md v0.6.0 agent-identity proposal. Use for "implement auth.md", "add agent registration", "design delegated agent signup", "support service_auth", "mint or verify an ID-JAG", "build an agent identity provider", or agent-facing OAuth consent, claims, and revocation. Distinct from Better Auth Agent Auth Protocol, OAuth Dynamic Client Registration, and RFC 8628 Device Authorization.

check-version skill icon
by bOpen

check-version

Compare installed plugin versions against GitHub to confirm skills and agents are current. Use at session start, for "is everything up to date", "are my plugins up to date", "are our plugins current", "check for plugin updates", "is anything stale", "am I on the latest version", "did that plugin update land", or when a skill behaves differently than documented or references features you do not recognize. Checks any plugin in the marketplace, not just core. Completes in under 100ms per plugin.

by bOpen

codex-agent-setup

Generate and install Codex agent adapters so plugin personas are invocable from the Codex CLI. Use for "set up codex agents", "install the codex adapters", "make these agents work in Codex", or when a persona is missing from a Codex session.

confess

A deliberate final-pass audit for incomplete work, untested assumptions, hidden concerns, and cleanup debt.

front-desk skill icon
by bOpen

front-desk

Route to the right agent, skill, or service provider. Use for "who handles X?", "what agents are available?", "team roster", "what skills are available?", "where do I find skill X?", "who should I talk to about Z?", "install in Grok Bot", "stand up the roster", or "Grok Bot teammates". Also covers agent-adapter availability, installing skills, and org email drafting. Route SOC 2 and audit readiness to Anthony in product-skills.

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.

authored
hook-manager skill icon
by bOpen

hook-manager

List, enable, or disable individual core hooks and check their prerequisites. Use for "list hooks", "enable a hook", "disable a hook", "hook setup", "hooks config", or a [BOPEN-HOOKS-SETUP] directive. For the full harness view, use setup.

humanize

Remove synthetic rhythm and generic phrasing from messages, documentation, reports, and public-facing copy.

linear-planning skill icon
by bOpen

linear-planning

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".

restraint

YAGNI with a governor: write the least code that is still the right code. This skill should be used on any coding task — writing, adding, refactoring, fixing, reviewing, designing code, or choosing libraries and dependencies — and whenever the user says "restraint", "/restraint", "don't over-build", "don't over-engineer", "keep it minimal", "simplest solution that works", "yagni", "do less", or complains about bloat, boilerplate, speculative scope, or unnecessary abstractions. Supports intensity levels off, lite, full (default), and ultra. Do NOT use for non-coding requests (general knowledge, prose, translation, summaries, recipes).

authored
runtime-context skill icon
by bOpen

runtime-context

Use when the user asks what runtime or host is active, which capabilities are available, or how behavior should adapt across Claude Code, Codex, Grok, OpenCode, a sandbox, or local development. Reports observed capabilities without inferring tools from host identity.

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 with optional user-triggered installation of selected dependencies. 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.
