Plugin marketplace
Claude Mods and the tools to build them: a builder skill, then mods.

Then install any plugin below by name — each page has its exact command.
A skill that plans, writes, validates, proves, reviews, migrates and publishes Claude Code mods. Plan first with the smallest $ surface, a footprint diffed against the plan, a test seen failing, an isolated load that leaves evidence files, a five-line threat model, and a handoff that names what was and was not proven. Brainstorm mode checks ideas against every mod already on GitHub.

cache-tax, the Mod. Stops a cold send once with its price, keeps the 1-hour prompt cache warm for a window you set (/keepwarm 6h), arms that for you after a paid cold write, and keeps score. Reach L2, one $.model.fork per idle stretch, its own store, a status slot; sees prompt length only.
Pins every subagent to the fable model by rewriting agent.spawn, with /fable-pin on, off and status. Reach L0: its own store and one command, nothing else.
Preview pasted images at their prompt markers on macOS. Ghostty, plus experimental iTerm2 and Herdr support with a startup override. Reach L2: local clipboard capture and temporary files, no model or network calls.
[probe] Loaded headlessly by mod-builder so the engine writes the running build's types. Not a mod to install.
