Curated by Skill Harbor — a context-curation skill from Addy Osmani's engineering workflow collection, built on one premise: context is the single biggest lever for agent output quality — too little and it hallucinates, too much and it loses focus. It structures context from most persistent to most transient (rules files, spec/architecture docs, relevant source files, error output, conversation history), tells you when to reach for it (new session, degrading output, task switching, new project setup), and makes the rules file (CLAUDE.md) the highest-leverage artifact you own. Distinct from the already-published addyosmani skills — none of them cover context strategy. By @addyosmani, listed here with credit to its creator. Honest caveats: it's a practice, not a plugin — the skill won't measure your context window for you; garbage in the rules file means garbage out of the agent. Skill Harbor never reviews the code, review it yourself before use.

Install
Prerequisites: none — works with any AI coding agent Install "Context Engineering" for me. Feed agents the right information at the right time — the context hierarchy from rules files to conversation history Repository: https://github.com/addyosmani/agent-skills/blob/main/skills/context-engineering/SKILL.md 1. Fetch the SKILL.md file for the addyosmani-context-engineering 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-context-engineering". 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.
