App Evolver

An orchestration skill that improves an existing app using its code, product contract, authorized work history and competitor evidence, then verifies the real user-facing result.

What it does

  • Binds the target first: exact app, repo/ref, runtime, current product contract, protected behavior/data, acceptance evidence and stopping condition.
  • Grounds opportunities in real evidence — existing user journeys, tests, owners, authorized session history and competitors' actual implementations, not feature lists.
  • Forces a decision table per candidate mechanism: evidence, user benefit, existing equivalent, fit and cost, adopt/adapt/reject, next probe.
  • Implements the smallest useful increment through the repository's real engineering workflow, honoring analysis-only vs. implementation authorization.
  • Verifies at the layer where the result is consumed, separates source/synthetic/runtime/packaged/production evidence, and reports what remains unverified.

Who it's for

  • Developers and PMs evolving a live application by user outcome rather than feature count.
  • Teams borrowing ideas from competitors who need to keep inspiration, code reuse and distribution rights as separate questions.
  • Anyone maintaining sibling apps (desktop/mobile) where contracts differ and assumptions leak across.

Examples

  1. "Study how competitor X does offline sync and improve ours" → gather implementation evidence → fit decision → minimal increment → verify via a real sync journey.
  2. "Revisit our failed performance optimizations" → mine authorized history, retry only when structurally new evidence appears.
  3. "Analysis only, don't touch the code" → read-only pass producing an opportunity/constraint table, recommendations and the product choices the user must decide.

Install in the Claude app (no terminal)
  1. Download the ZIP with the button below.
  2. In Claude, open Settings → Capabilities and turn on 'Code execution and file creation'. (one time)
  3. Go to Customize → Skills → + → 'Upload a skill' and upload the ZIP.
↓ Download ZIP
Install in Claude Code

Let Claude do it — paste this into Claude Code

Install the skill I found on Claude Skill Mart.
Copy the app-evolver folder from the GitHub repo daymade/claude-code-skills into my ~/.claude/skills/app-evolver/.
When it's done, tell me in one line what this skill can do.

Install with a command instead

git clone https://github.com/daymade/claude-code-skills.git /tmp/ccs && mkdir -p ~/.claude/skills && cp -r /tmp/ccs/app-evolver ~/.claude/skills/

⚠ This is a third-party skill. Check the source repository before installing.

  1. Open a terminal.
  2. Clone the repo: git clone https://github.com/daymade/claude-code-skills.git
  3. Create the skills directory: mkdir -p ~/.claude/skills
  4. Copy the skill: cp -r claude-code-skills/app-evolver ~/.claude/skills/
  5. Confirm the bundled docs came along: ls ~/.claude/skills/app-evolver/references
  6. Optionally copy the companion skills skill-evolver and competitors-analysis, which this skill delegates to.
  7. Restart Claude Code and try: "Improve this app, referencing how competitors solve it."
