Eval Rubric Generator
Build an eval rubric that catches real regressions — 4-8 specific criteria measuring observable behaviors (not subjective 'quality'), with scoring approach, edge cases, and a run plan with kill criteria.
Synthetic Test Case Generator
Generate 30-100 synthetic test cases (happy path, edge cases, adversarial) that look like real production traffic — not invented inputs that bear no resemblance to what the prompt actually sees.
SKILL.md Audit Tool
Audit a Claude SKILL.md or prompt artifact for frontmatter validity, injection surface, instruction contradictions, and length budget. Specific findings with severity (P0/P1/P2) and fixes.
Regression Report Generator
Write a regression report after a prompt or skill change — headline decision up front, per-criterion deltas with threshold checks, subgroup regression notes, and specific failure mode analysis.

The problem
Where your time is going
These are the documented time-sinks for Prompt Engineers — the tasks that AI can help most.
Prompts regress when changes ship
A small edit to one instruction silently breaks five existing flows. Without an eval set, the regression isn't caught until users complain — sometimes weeks later.
No objective way to compare two prompt variants
Two variants both 'feel better' on three hand-picked examples. Without paired evals and statistical tests, ship decisions become gut calls and team debates.
Skill quality varies wildly across community libraries
1,400+ community Claude skills exist with no shared quality bar. Frontmatter is missing, prompt-injection surface is exposed, length budgets are blown — and there's no plugin to audit any of it.
The solution
What AI can do for Prompt Engineers
Specific use cases with real time savings — not generic AI promises.
Synthetic Test Case Generation
2 hrs → 5 minStress-test a prompt with 50–100 synthetic cases covering happy path, edge cases, and adversarial inputs — instead of three hand-picked examples.
Statistical-Significance A/B Testing
4 hrs → 10 minCompare two skill variants on a paired eval set with bootstrap resampling. Get a p-value, effect size, and subgroup regression check before shipping.
Automated Prompt Optimization Loops
1 day → 1 hrCluster failures from real traces, propose targeted prompt edits, and re-run the eval — turning a slow manual loop into a tight iteration cycle.
