Unpack the archive. Then open a terminal in the parent folder containing the extracted `offerskill` directory and run `claude --plugin-dir ./offerskill`. Plugin command: `/offerskill:kp <domain>`.

Claude Code Plugins documentation

Claude.ai and Cowork

The `skills_zip` folder contains the archives for all skills. Open Customize → Skills → + → Create skill → Upload a skill, then upload the required archives one at a time. For the full process, create an OfferSkill project and add the agent text from `agents/offerskill.md` to the project instructions. If the environment has no subagents, run the independent critic in a separate chat using `agents/offerskill-critic.md`.

Claude Skills help

Optional collectors for Google Search Console, Yandex Metrica, Keys.so, Ahrefs, and the BAR adapter require user API keys and configuration. By default, the Ahrefs script makes up to 20 API requests per run; this is a request count, not a count of API units. Only uncached requests consume units. The cost per request is the greater of 50 base units and the per-row cost of selected, filtered, or sorted fields multiplied by the number of rows; some metric fields cost 5 or 10 units per row. The response header x-api-units-cost-total-actual shows the units actually consumed. Set an API limit and confirm the plan before running it. The archive contains no keys. The script limits request count only; it does not calculate total API units. If all 20 requests miss the cache, the base cost alone is at least 1,000 units; larger result sets and higher-cost metrics can cost more. Before running, check the remaining units on your plan and inspect both the x-api-units-cost-total-actual and x-api-cache response headers.
