Curated by Skill Harbor — build in thin vertical slices instead of implementing a whole feature in one pass: each slice (e.g. create task DB + API + basic UI) leaves the system working and testable. The increment cycle: implement the smallest complete piece, test it, verify it, commit it with a descriptive message, move to the next slice. Prefers vertical slices (one complete path through the stack per slice) and covers slicing strategies plus feature-flag rollout discipline. Distinct from its sibling shipping-and-launch: this skill is about the build discipline during implementation; shipping-and-launch is about pre-launch checklists, staged rollout, and rollback at release time. When NOT to use: single-file, single-function changes where the scope is already minimal. By @addyosmani, listed here with credit to its creator. Skill Harbor never reviews the code, review it yourself before use.

Install
Prerequisites: none Install "Incremental Implementation" for me. Thin vertical slices — implement, test, verify, commit, next slice Repository: https://github.com/addyosmani/agent-skills/blob/main/skills/incremental-implementation/SKILL.md 1. Fetch the SKILL.md file for the addyosmani-incremental-implementation skill from the repository into a temporary folder and summarize what it does in one or two sentences. 2. Safety check: review the SKILL.md and scripts for anything suspicious (unexpected network calls, shell commands, credential harvesting). This repo should contain zero secrets in code, credentials only via the secure vault, allowed hosts declared in the SKILL.md. Verify that holds here; STOP on any red flag and tell me. 3. Install it as a skill: copy SKILL.md and its helper files into the agent's skills directory, in a folder named "addyosmani-incremental-implementation". 4. Verify with no network calls: frontmatter valid, files in place. 5. Report what was installed, where, and what I still need to do myself (e.g. any accounts, API keys, or CLI tools mentioned in the prerequisites above). GitHub is optional: if I have a GitHub account or the gh CLI, you may use it; otherwise public access is fine. Never require it unless it's in the prerequisites above. Rules: don't touch anything outside the temp folder and the install target. Never ask me to paste secrets in chat — credentials go through the secure vault or environment variables. If anything looks off, stop and ask me.
Questions
How do I install a build?
Every product page includes a copy-paste install prompt. Paste it into your Muse and it sets the build up for you — no manual configuration.
Where does my money go?
Straight to the seller. Skill Harbor never processes payments: checkout happens on the seller’s own page, usually Stripe.
What does the ✓ next to a creator’s name mean?
It means we confirmed the identity of the person behind the listing. It says nothing about the code itself — always check a build before installing it.
