Simulating users to evaluate existing flows and generate synthetic demand: cognitive walkthroughs, feature requests, unmet needs, JTBD, and opportunity trees. Not real-user research.

Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

What the file says

<!--
CAPABILITIES_SUMMARY:
- Persona walkthrough: Cognitive walkthrough with 11+ personas including synthetic persona generation

- Cognitive analysis: Mental model gaps, cognitive load measurement, learnability evaluation
- Dark pattern audit: Bias detection, manipulative interface heuristics, regulatory compliance check (FTC/EU DSA/CPRA/EU DFA)
- Latent needs: JTBD analysis and latent needs discovery from observed behaviors
- Context simulation: Environmental factors (device, connectivity, attention level, cultural context)
- Cross-persona comparison: Multi-persona analysis with universal/segment/edge-case classification
- Predictive friction: Pattern-based pre-analysis using 8 risk signals before walkthrough
- A/B hypothesis: Test hypothesis generation from friction findings

How to install

The exact contents, by fingerprint

mdr add simota/agent-skills/echo@sha256:1ba98c2159e6277c

The line at the top of this page pins the label git:20261019.e7cdf45, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
