BC line-length-optimizer

Use when checking or fixing the measure (line length) of a text block — verifying a paragraph or container sits in the 45–75 character range (35–45 on mobile) per Bringhurst/Latin readability guidance, and producing a max-width/ch fix.

How to improve

  1. The text references files that are not there: add them or drop the references.
For the model run — optional
  • 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.

Against the Agent Skills spec

  • warning missing-ref reference to a missing file: ../microtypography/SKILL.md
  • note frontmatter-key unknown frontmatter key "triggers"

Process rating: all ten parameters 55/100

Will not run. References files that are not bundled: ../microtypography/SKILL.md
  • 0Tools and files. 1 referenced file(s) missing: ../microtypography/SKILL.md
  • 0Result and completion. Does not say what the result is
  • 50When it triggers. No condition that starts the skill
  • 65Failures and branches. 3 branches
  • 70Inputs and preconditions. Inputs and preconditions are listed
  • 100Steps. 44 steps
  • 100Consistency. Name and required fields are in place
  • 100Execution cost. Instruction body is 1760 tokens
  • 100Running it twice. No mutating operations
  • 100Progress reporting. Reports progress

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.
