AC openclaw-regex-engine

Production-grade regex processing suite — test patterns with capture groups, explain any regex in plain English, build regex from natural language descriptions, browse 50+ battle-tested patterns, and find-replace with backreferences. Use when: (1) user says 'test this regex' or 'does this pattern match', (2) user asks 'explain this regex' or 'what does this regex do', (3) user needs to 'build a regex for emails' or 'create a pattern that matches URLs', (4) user wants a 'ready-made regex for phone numbers' or 'UUID pattern', (5) user requests 'regex find and replace' or 'search and replace with backreferences'. Supports all ES2024 flags, named groups, lookahead/lookbehind. Zero install, sub-100ms on Cloudflare Workers. Free + Pro $9/mo.

How to improve

    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.

    Process rating: all ten parameters 53/100

    • 0Result and completion. Does not say what the result is
    • 0Inputs and preconditions. Does not say what the process needs to start
    • 0Failures and branches. Linear process with no failure handling
    • 0Progress reporting. Says nothing while it works
    • 20When it triggers. No condition that starts the skill
    • 100Tools and files. No external tools needed
    • 100Steps. 10 steps
    • 100Consistency. Name and required fields are in place
    • 100Execution cost. Instruction body is 2439 tokens
    • 100Running it twice. Mutating operations check current state
    • medium Safety rules and hard prohibitions inside a skill: they belong in the system prompt, here they protect nothing

    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
    • +4Description does not say when NOT to use the skill (false activations)
    • +3Output format is not stated: the model decides each time
    • +1No license
    • +2Single-language instructions
    • +3Description length 745: enough signal without eating the budget
    • +4Structure: 17 headings
    • +3Step-by-step instructions: 10 items
    • +4Has examples (5 code blocks)

    Quality base 70; lint remarks subtract, signals add up to 100. Result: 82.
