Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00000 | $0.00335 |
| Opus 5.5 | $0.00000 | $0.00134 |
| Sonnet 5.5 | $0.00000 | $0.00067 |
| Haiku 4.5 | $0.00000 | $0.00034 |
Grade A, and why
supabase-schema-generator 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 1mo 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.
What it actually says
🗄️ Skill: supabase-schema-generator
An SRE-grade automation skill to parse SQL schemas and auto-generate safe TypeScript interfaces for the frontend and Row Level Security (RLS) policies for Supabase.
🛠️ Triggers
This skill is triggered when an agent or developer needs to translate database tables into frontend types, secure Supabase tables, or generate RLS scripts.
- "generate supabase rls"
- "build typescript database types"
- "run supabase-schema-generator"
- "create db types"
🚀 Usage Guide
Requirements
- Python (3.10+)
google-genaipackage installed (viauv)- A valid
GEMINI_API_KEYdefined in the environment or in the global.hermes/.envfile.
Command Execution
Run the script using uv run from the repository root:
# Generate types and RLS policies from schema.sql
uv run --with google-genai skills/automation/supabase-schema-generator/scripts/generator.py \
--schema database_schema.sql \
--output-types src/types/database.ts \
--output-rls supabase/migrations/policies.sql
Options
-s,--schema: Path to the input SQL schema file (required).-t,--output-types: Path to save the generated TypeScript types (default:types.ts).-r,--output-rls: Path to save the generated RLS SQL script (default:policies.sql).
What ships with it
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.
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.

supabase-schema-generator is a skill published in the GitHub repository aragaobruno/toolbelt (2 stars, last pushed 3mo ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 335 tokens. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.

drizzle-orm-expert
Expert in Drizzle ORM for TypeScript — schema design, relational queries, migrations, serverless DB integration. Use when building type-safe database layers with Drizzle, migrating from Prisma, or optimizing edge runtime DB access.
drizzle-orm
Drizzle ORM best practices. Use when configuring databases, designing schemas, writing queries, or handling migrations with Drizzle ORM, particularly with Cloudflare D1 or SQLite. NOT for database setup without an explicit engine. Require engine specification (Postgres/MySQL/SQLite). Use for ORM-managed migrations.
psl-ast-layers
How to use the PSL syntax tree layers (green tree, red tree, strongly-typed AST classes) correctly. Use for any PSL-related work: PSL interpreters (contract-psl), helpers inside the psl-parser package, the language server, formatters, or anything else that consumes parse() output from @internal/psl-parser.
ast-visitor-pattern
Use the frozen-class/visitor pattern for discriminated unions that have multiple dispatch sites. Use when creating a new set of variants (commands, IR nodes, factory calls) that will be switched over in 2+ places, or when refactoring an existing union type that has grown multiple switch sites.
no-bare-casts
Writing as in TypeScript or TSX production code, modifying a file that contains a bare as cast, silencing a type error with a cast, encountering as unknown as, or reviewing a cast site.
bumping-biome
Bumps biome package versions (e.g. @biomejs/biome) using pnpm, aligns biome.jsonc files with the new version/s across the repository and runs biome-related checks. Use when required to update biome to a newer version - explicitly or implicitly (e.g. after running pnpm up, pnpm update, pnpm upgrade without specific…
