Curated by Skill Harbor — a focused authorization specialist, not a general reviewer. It finds and fixes the four defect shapes that account for the largest measured defect cluster in generated Convex backends: identity-from-arg impersonation, missing per-document ownership checks, public queries leaking data via a client-supplied id, and writes into a parent/container the caller doesn't own. It runs a deterministic regex-based scan first, then applies the canonical `requireIdentity`/`requireOwner` hardening pattern to every hit, then verifies with `tsc`. Mandatory first step: it checks the auth foundation exists (an auth.config.ts with a provider, and a users/identities table keyed to the auth subject) — on a foundationless app it refuses to inject unenforceable `ctx.auth` checks and instead converts privileged operations to internal functions while telling you to set up auth first. Sibling of convex-reviewer (the broad reviewer) and convex-expert (the idioms). Requires a Convex account and project. By @get-convex, listed here with credit to its creator. Skill Harbor never reviews the code, review it yourself before use.

Install
Prerequisites: a Convex account and a Convex project Install "Convex Authorization Auditor" for me. Audit and harden a Convex app's authorization — the four defect shapes, fixed and verified Repository: https://github.com/get-convex/agent-skills/blob/main/skills/convex-authz/SKILL.md 1. Fetch the SKILL.md file for the get-convex-convex-authz 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 "get-convex-convex-authz". 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.
