AC 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.

How to improve

    For the model run — optional
    • A spec.yaml with trigger phrases and assertions — a behaviour contract for CI; `skilltest init` writes a template.

    Guard findings · 0

    ✓ No critical or high findings

    Files scanned: 14. Evidence is masked. Grey chips explain why severity was lowered.

    Process rating: all ten parameters 58/100

    • 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
    • 55Failures and branches. 1 branches
    • 60Tools and files. Uses tools (web) that frontmatter does not declare
    • 70When it triggers. States when to use, but not when not to
    • 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.

    External checks

    ClawHub: suspicious
    This skill appears intended to manage a Hardcover reading account, but it combines account-changing commands and token access with under-scoped execution and unpinned npx-based runtime dependencies.
