AB hardcover-bookshelf
Talk to a user's Hardcover bookshelf via the Hardcover GraphQL API. Use when the user wants to manage reading activity in natural language: start a book, finish a book, view the Want to Read shelf, or compute yearly reading stats such as "how many books did I read last year?". Require HARDCOVER_TOKEN before any API call, using the exact `Bearer ...` value copied from Hardcover account API settings. Use this skill whenever the user mentions Hardcover, reading lists, bookshelves, tracking books, or anything related to managing what they're reading.

Process rating: all ten parameters 66/100
- 0Result and completion. Does not say what the result is
- 0Inputs and preconditions. Does not say what the process needs to start
- 0Progress reporting. Says nothing while it works
- 70When it triggers. States when to use, but not when not to
- 70Failures and branches. 4 branches
- 100Tools and files. No external tools needed
- 100Steps. 22 steps
- 100Consistency. Name and required fields are in place
- 100Execution cost. Instruction body is 746 tokens
- 100Running it twice. No mutating operations
- medium Safety rules and hard prohibitions inside a skill: they belong in the system prompt, here they protect nothing
- medium 6 test cases, all positive: not one "should refuse" or "should ask first"
- low No test case covers injection arriving through data
Everything here is measured from the skill text rather than judged by a model, so the numbers are checkable. A parameter weighs more when it is a more common reason for the process to stall.
