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 | $0.00040 | $0.00163 |
| Opus 5 | $0.00020 | $0.00081 |
| Sonnet 5 | $0.00008 | $0.00033 |
| Haiku 4.5 | $0.00004 | $0.00016 |
Grade A, and why
postgres 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
Execute SQL queries against the local Postgres database using psql.
Pipe the query via stdin:
echo "<SQL_QUERY>" | PGPASSWORD=c0d3ly7v psql -h localhost -p 5432 -U supabase_admin -d postgres -tA
Tips
- If you need to discover schemas or tables, query
information_schema.tablesdirectly instead of reading migration files. - Go straight to the query. No need to inspect Docker or init scripts beforehand.
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.

postgres is a skill published in the GitHub repository CodelyTV/agentic_programming-course (38 stars, last pushed 4mo ago), licensed MIT. It adds 40 tokens to every session and 163 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 2026-08-30.
