AC regex-toolkit
Test, match, extract, replace, explain, and validate regular expressions from the command line. Includes a library of 25+ common patterns (email, URL, IP, phone, date, UUID, etc.) that can be used by name. Use when the user needs to build, debug, or test regex patterns, extract data with regex, do search-and-replace with backreferences, or understand what a regex does. Zero external dependencies.
As a process C 52/100 · Has gaps — weak spots: steps, result and completion, failures and branches
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 52/100
- 0Steps. Prose only: no discrete steps
- 0Result and completion. Does not say what the result is
- 0Failures and branches. Linear process with no failure handling
- 0Progress reporting. Says nothing while it works
- 70When it triggers. States when to use, but not when not to
- 70Inputs and preconditions. Inputs and preconditions are listed
- 100Tools and files. No external tools needed
- 100Consistency. Name and required fields are in place
- 100Execution cost. Instruction body is 555 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.
Quality signals
- +5Description has no quoted example phrases that should trigger the skill
