DevVerse-SWE-Blog: Skill for Codex

.agents/skills/devverse-supabase-auth/SKILL.md

devverse-supabase-auth is a skill for Codex from hoangsonww/DevVerse-SWE-Blog. It costs 43 tokens per session (217 once invoked), scanned A, original, MIT.

A set of rules for handling Supabase authentication, favorites, profiles, and storage helpers in a web application. Supabase is a hosted service that provides features such as user accounts and data storage.

In plain words
What is it for?
Use it when changing Supabase files, sign-in flows, favorites, storage helpers, email verification, or password-reset APIs.
Why use it?
It keeps browser and server responsibilities separate and protects sensitive authentication routes from unsafe code sharing.

Skill for Codex

Written for Codex: agents/openai.yaml present. Also seen: installed under .agents/ (shared by several agents).

This is hoangsonww/DevVerse-SWE-Blog's own configuration. It tells Codex how to work on DevVerse-SWE-Blog 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 DevVerse-SWE-Blog 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

devverse-supabase-auth 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 yesterday.

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.

What it actually says

DevVerse Supabase Workflow

  1. Keep anon and service-role responsibilities separate. Browser-facing auth, favorites, and storage helpers use the anon client. Service-role usage must stay server-only.

  2. Treat verify-email and reset-password routes as security-sensitive. Those routes are publicly callable and currently enumerate users via listUsers({ perPage: 1000 }).

  3. Do not move service-role code into shared modules imported by client code.

  4. Remember what Supabase is and is not used for here. Supabase handles auth, favorites, and some profile/storage helpers. It is not the runtime source of article content.

  5. Read the runtime boundaries before changing auth or favorites behavior. @references/runtime-boundaries.md

  6. After auth route changes, run repo tests and state any real-env validation you could not perform.

2 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

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.
