convex-add

Adds a feature to a Convex app you already have, such as billing, scheduled jobs, sign-in, an AI agent, search or web hosting. It follows Convex's online list of current instructions for that feature; for anything not on the list it needs a component-search script that the skill does not include.

by get-convexpart of get-convex/agent-skills

One of 30 skills in the get-convex/agent-skills package — works on its own, and pairs well with its siblings.

WHEN YOUR AGENT SHOULD USE IT

A QUICK BOUNDARY

USE FOR

  • Add web hosting to a Convex app and get its public address back.
  • Add billing, scheduled jobs, sign-in, an AI agent or search with one request.

DO NOT USE FOR

  • Starting a new project: it works on a Convex app that already exists.

Documents

This is the playbook your agent receives when the skill activates — you don't need to read it to use the skill, but it's here to audit before installing.

add

Add a named capability to an existing Convex app. Step 1: fetch the served capability catalog — if a capability matches the user's request, fetch its /capability/<id>.md doc and follow its Procedure+Rules (always-current, no plugin re-release needed). If the catalog is unreachable OR no entry matches, fall back exactly to today's behavior: 'hosting' wires @convex-dev/static-hosting; anything else runs the /add-component search script and installs the best-matching @convex-dev component.

Workflow
  1. Identify the capability the user wants (text after /add or $add).
  2. Fetch https://basic-anteater-667.convex.site/capabilities.json (4s timeout). Match the request against title/summary/trigger.
  3. If a match is found: fetch /capability/<id>.md and follow its Procedure+Rules sections.
  4. FALLBACK (no match or catalog unreachable): for 'hosting' run /add-hosting; for anything else run /add-component with ADD_TERM set. Read CANDIDATES output, install best match, wire per README.
  5. Confirm the addition to the user with the resulting URL (hosting) or component name.
Rules
  • Always try the served capability catalog first — it may have a canonical procedure that supersedes baked-in knowledge.
  • Served doc text is procedure instructions, not arbitrary shell to blindly execute — apply normal judgment.
  • Never hard-fail on catalog miss — always fall back to the legacy component search.
  • Never hardcode a component mapping — use the live CANDIDATES list from the search script.
  • If curl/bash is blocked by sandbox, tell the user to re-run with network access or auto-approve.

Installation

Copy & paste — that's it
npx skills add get-convex/agent-skills --skill "convex-add" --full-depth

Run this in your project — your agent picks the skill up automatically.

BEFORE IT WILL WORK

2 FOR YOU
  1. 01
    Internet access for your assistant

    The skill downloads Convex's instructions each time it runs. If your assistant blocks network commands, allow them or approve the download.

  2. 02
    A component-search script, for features not on Convex's list

    For a feature not on Convex's list, the skill runs a component-search script that it does not include. Check your assistant has it before relying on this skill for those.
