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 | $0.00134 | $0.08964 |
| Opus 5 | $0.00067 | $0.04482 |
| Sonnet 5 | $0.00027 | $0.01793 |
| Haiku 4.5 | $0.00013 | $0.00896 |
Grade A, and why
israeli-postgres-toolkit 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 5d 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.
How it starts

Israeli Postgres Toolkit
Best practices, patterns, and scripts for building PostgreSQL databases tailored to Israeli applications. Covers Hebrew text handling, shekel currency, Israeli timezones, Supabase integration, and common Israeli data types.
Assumes PostgreSQL 13+ (the patterns use gen_random_uuid() from core, non-deterministic ICU collations need 12+, and generated columns need 12+). Current stable is PostgreSQL 18.
Instructions
Follow this workflow when setting up or reviewing a PostgreSQL database for an Israeli app:
- Verify encoding and timezone first. Run
SHOW server_encoding;(must beUTF8, neverSQL_ASCIIorLATIN1) andSHOW timezone;. Set the database timezone withALTER DATABASE your_db SET timezone = 'Asia/Jerusalem';. Getting these wrong corrupts Hebrew and offsets every timestamp, and fixing it later means a data migration. - Pick the collation strategy. Decide per column whether you need Hebrew display ordering (a non-deterministic ICU collation built from locale
he-IL) or byte-exact prefix search (the default deterministic collation). A non-deterministic collation supportsUNIQUEconstraints andbtreeindexes. From PostgreSQL 18 it also supportsLIKE, butILIKEand regular expressions still error, andLIKEcannot use a btree prefix index. See the operator matrix below before choosing. - Choose the search approach. For exact and prefix matching use
btree. For fuzzy/typo-tolerant Hebrew search usepg_trgm. For multi-field ranked search use full-text search with thesimpleconfiguration (see "Full-Text Search with Hebrew" below). For Hebrew matching that ignores nikud, maqaf and gershayim use thenormalize_hebrew()function shown below, applied to BOTH the column and the query;unaccentonly strips Latin diacritics, not Hebrew nikud. - Apply Israeli data-type constraints. Use the
CHECKconstraints and helper functions fromscripts/israeli-data-types.sql(teudat zehut, phone, postal code, business number, IBAN) and callvalidate_teudat_zehut()for the ID check digit rather than reimplementing it in application code.
What ships with it
9 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.

israeli-postgres-toolkit is a skill published in the GitHub repository skills-il/developer-tools (10 stars, last pushed 3d ago), licensed MIT. It adds 134 tokens to every session and 8,964 once invoked, about $0.0007 per session on Opus 5. 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.
