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 | $0.00046 | $0.01298 |
| Opus 5 | $0.00023 | $0.00649 |
| Sonnet 5 | $0.00009 | $0.00260 |
| Haiku 4.5 | $0.00005 | $0.00130 |
Grade A, and why
postgresql-connection 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 2d 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.

PostgreSQL Connection Skill
On Entry
Tell the user:
Setting up PostgreSQL connection — I'll configure and test a connection to your source PostgreSQL database. I'll need a few connection details.
Prerequisites
- Network access to the PostgreSQL host (managed: RDS / Cloud SQL / Azure / Supabase / Neon, or self-hosted)
- PostgreSQL username and password
- The
scaiCLI installed and available
Required Connection Details
Standard Auth (only auth method supported in MVP)
| Parameter | Required | Description |
|---|---|---|
-c, --connection |
Yes | Friendly name for this connection |
--auth |
Yes | standard |
--host |
Yes | PostgreSQL host |
--port |
No | TCP port (default: 5432) |
--database |
Yes | Database name |
--user |
Yes | PostgreSQL username |
--password |
Yes | PostgreSQL password |
--ssl-mode |
No | One of Disable, Allow, Prefer, Require, VerifyCA, VerifyFull (default: Require) |
--connection-timeout |
No | Connection timeout in seconds |
SSL defaults to
Requireso managed PG (RDS, Cloud SQL, Azure, Supabase, Neon) works out of the box. For local Docker / dev, override with--ssl-mode Disableexplicitly.
Workflow
Step 1: Ask How to Provide Credentials
Ask the user:
"I need the following to connect to PostgreSQL:
- Host
- Port (default
5432)- Database name
- Username and password
- SSL mode (default
Requireis right for managed PG)How would you like to provide these?"
Options:
- 1Password — Credentials stored in 1Password vault
- Enter manually — Provide values directly
Step 2: Route Based on Answer
| User says | Action |
|---|---|
| "1Password" | Follow ../1PASSWORD.md (PostgreSQL section) |
| "Enter manually" | Proceed to Step 3 |
| Other credential manager | Check if ../references/<NAME>.md exists; if not, ask user to explain their setup |
Step 3: Add the Connection
What ships with it
1 file 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.

postgresql-connection is a skill published in the GitHub repository sfc-gh-dflippo/snowflake-dbt-demo (33 stars, last pushed 3d ago), licensed Apache-2.0. It adds 46 tokens to every session and 1,298 once invoked, about $0.0002 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 2026-09-10.
