⚠ This skill is no longer available upstream. Our re-check on Aug 10, 2026 couldn't find it any more (repo unreachable/deleted). The test below is what we measured on Aug 5, 2026 and we're leaving it up as a record — but there is nothing left to install, so we've removed the command.
The command the skill tells you to run — `brand-loom run caption --text "..." --platform twitter` — dies with 'unrecognized arguments: --platform' against both the published 0.1.1 package and the repo's own CLI, which has no platform flag anywhere in it. Drop the flag and it runs, but the default provider is 'fake' and it returns {"result": "fake-response"} instead of a caption; a real one needs a paid provider key, so the actual copy quality is untested. The SKILL.md carries no caption-writing guidance at all — the prompt with the platform rules and few-shot examples lives inside the Python package, unreachable to an agent reading the skill — so following the body strictly produced no usable caption where simply writing one unaided did. Both the description and the body also route readers to the author's hosted paid service.

What Caption Writer does
A thin pointer to the brand-loom Python package's caption generator, meant to produce social media post copy for a given topic with optional brand voice context. The skill file itself holds no writing guidance — the caption prompt lives inside the pip package, so all real work happens in an external CLI that needs a provider API key. Triggers on requests for social captions or post copy for a platform.
How to install Caption Writer
Nothing to install: the source repository no longer has this skill. If the author brings it back, our daily re-check will pick it up and the command will reappear here.
