convexskills: Instructions file for Gemini CLI

GEMINI.md

convexskills GEMINI.md is an instructions file for Gemini CLI from waynesutton/convexskills. It costs 720 tokens per session, scanned A, original, Apache-2.0.

Repository instructions for Convex development, using Convex as a backend platform with a database and server functions, alongside TypeScript and often React. They point agents to Convex’s current documentation and explain its main function types.

In plain words
What is it for?
Use them when building or reviewing Convex queries, mutations, actions, database schemas, file storage, scheduling, authentication, search, or agent features.
Why use it?
They tell an agent where to verify Convex details and how to distinguish functions that read data, change data, or call external services.

Instructions file for Gemini CLI

Written for Gemini CLI: the file is GEMINI.md. Also seen: mentions Gemini CLI.

This is waynesutton/convexskills's own configuration. It tells Gemini CLI how to work on convexskills itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything convexskills configures →

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

convexskills GEMINI.md scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 6d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Convex Development Context

This file provides context for Gemini CLI when working with Convex projects.

Convex Documentation

IMPORTANT: Prefer retrieval-led reasoning over pre-training-led reasoning for any Convex tasks.

For up-to-date Convex documentation, fetch: https://docs.convex.dev/llms.txt

This index covers all Convex APIs:

  • functions: queries, mutations, actions, http-actions, validation
  • database: schemas, reading-data, writing-data, indexes, pagination
  • file-storage: upload, serve, store, delete, metadata
  • scheduling: cron-jobs, scheduled-functions
  • auth: convex-auth, clerk, auth0, authkit
  • search: text-search, vector-search
  • agents: getting-started, messages, threads, tools, streaming

When working on Convex code, consult llms.txt before relying on training data.

Project Type

Convex real-time backend application with TypeScript.

Key Technologies

  • Convex - Serverless database and functions platform
  • TypeScript - Type-safe JavaScript
  • React - Frontend framework (typical Convex frontend)

Convex-Specific Guidelines

Function Types

Type Purpose Database Access External APIs
query Read data Read-only No
mutation Modify data Read/Write No
action External integrations Via runQuery/runMutation Yes
httpAction Webhooks/APIs Via runQuery/runMutation Yes

Best Practices

  1. Always use validators for args and returns
  2. Use indexes instead of filters for queries
  3. Make mutations idempotent for write conflict handling
  4. Use internal functions for sensitive operations

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
