Improves an existing application using its code, product contract, authorized work history and competitor evidence. Use for 取长补短、取其精华去其糟粕、参考竞品优化应用 or evolving an app from successful and failed work.

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
# App Evolver Improve the application's actual user result. Extract transferable mechanisms, resolve their fit with the current product, implement authorized improvements, and verify them through the application's consuming surface. Use this as an orchestration Skill. Keep repository engineering, research, history access and release operations with their existing owners. For a Skill target use `skill-evolver`; for competitor intelligence alone use `competitors-analysis`; for a new product specification use the available requirements workflow. Do not replace those owners with another execution engine. ## 1. Bind the application and unfinished result Before research or edits, establish: - Exact application, repository/ref, platform and runtime or deployment identity. - Original user request, current product contract and active stage; distinguish long-term positioning from the work selected now. - User-visible improvement, falsifiable acceptance evidence, authorized deliverables, protected behavior/data and stopping condition. - Analysis-only versus implementation authorization, and any unresolved product choice whose answer changes the outcome. …

How to install
mdr add daymade/claude-code-skills/app-evolver@sha256:4a62175e9b716cb5The line at the top of this page pins the label git:20261021.7b9a27e, 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.
