AB pdf2markdown
Convert PDF and image documents to clean Markdown via the PDF2Markdown CLI. Use when the user wants to extract text from PDFs, convert PDFs to markdown, parse document structure, or process images (JPEG, PNG, GIF, WebP, TIFF, BMP) into structured content. Also use when they say "convert this PDF", "parse this document", "extract text from PDF", "parse async", or "large file" (up to 100MB). Must be pre-installed and authenticated.
As a process B 70/100 · Nearly there — weak spots: steps, progress reporting
How to improve
- Your own cases (evals/evals.json, 4–6 real requests with expected answers): the full check would then run those instead of a model-drafted suite.
- A spec.yaml with trigger phrases and assertions — a behaviour contract for CI; `skilltest init` writes a template.

Process rating: all ten parameters 70/100
- 0Progress reporting. Says nothing while it works
- 25Steps. 1 steps
- 55Failures and branches. 1 branches
- 60Result and completion. Output format stated, no completion criterion
- 70When it triggers. States when to use, but not when not to
- 70Inputs and preconditions. Inputs and preconditions are listed
- 100Tools and files. Tools declared in frontmatter
- 100Consistency. Name and required fields are in place
- 100Execution cost. Instruction body is 652 tokens
- 100Running it twice. No mutating operations
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.
