Agent self-improvement runtime for Codex, Claude, and OpenCode
Skill Claude CodeCodex
Run Introspect for Codex sessions when the user asks Introspect to inspect recent corrections, update agent instructions, or report what it would remember.

How an LLM agent should emit a structured decision or host-consumed payload — a mode flag, control action, state change, routing choice, or UI data envelope — back to its host system. Use when building or debugging an agentic product where the host asks the model to return only JSON, signal…
Skill Codex
Create, edit, prune, review, and debug AGENTS.md or CLAUDE.md as the always-loaded agent prompt. Use for coreprompt decisions, global agent rules, prompt bloat, instruction failures, or placement decisions between AGENTS.md, hooks, and skills.

Keep Companion billing money values tied to source of truth: usage markup/credits in billing economics, and subscription plan prices across plan constants, Autumn/Stripe, RevenueCat, and App Store Connect when Apple IAP is in scope. Load when changing CREDITMARKUP, usage credit math, plan prices, top-ups, billing…
Skill Claude CodeCodex
Drive authenticated web-console and browser forms through semantic controls, Playwright/DOM locators, or form APIs instead of repeated coordinate clicks and blind keystrokes. Use when filling or editing forms in Chrome or the in-app browser, especially admin consoles, OAuth/client settings, secret managers, or pages…

Forecasting and decision support where money, deadlines, or irreversible choices matter; prevents weak-model language from becoming a refusal to build and test a predictive model.

Retrieve an API token, secret, GitHub credential, or remote-session auth path from the machine's own stores before asking the user to paste it or working around auth with file transfer. Use when a CLI errors on auth, an env var like SENTRYAUTHTOKEN is unset, a deploy/API call needs a key, or a remote SSH shell cannot…
Skill Claude CodeCodex
Register a folder as an Obsidian vault before handing off obsidian://open links on macOS, so the user actually opens what you generated instead of hitting "Unable to find a vault for the URL".
Skill Claude CodeCodex
Polish user-facing product surfaces such as pricing pages, plan cards, feature pages, grant/application packets, navigation rows, empty states, model/settings pickers, provider import/export prompts, provider logos, App Store/TestFlight metadata, icons, categories, onboarding, and marketing UI by reading real…
Skill Claude CodeCodex
Set per-plan caps, quotas, limits, and compute sizes in Companion's billing tiers by deriving the numbers from the existing price/credit ladder, not by inventing round or evenly-doubling numbers. Load when adding or changing a per-tier quantity (automations cap, storage, rate limit, feature quota, or per-plan…
Skill Claude CodeCodex
Restyle or build an in-app UI component (inputs, chips/tags, tabs, comboboxes, cards, dialogs, chat/message surfaces) by first identifying the right component archetype, reading real reference implementations, matching their concrete details and edge states, then verifying by viewing the rendered component. Use when…
Skill Claude CodeCodex
Remaster, upscale, or rebuild visual assets and sprite packs with image/upscale/edit APIs. Use when improving pixelated images, choosing GPT/Gemini/Fal/Flux/Topaz/Aura/ESRGAN-style providers, preserving transparent backgrounds, building contact-sheet batches, or generating a production asset pack. Not for ordinary UI…
Skill Claude CodeCodex
Write or revise model-facing prompt text so the desired behavior is stated as the output to produce, then verify it with real response probes. Use when editing AGENTS.md, CLAUDE.md, system prompts, prompt rules, or when prompt wording makes the agent explain, ask permission, or stall instead of acting.
