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 | $0.00083 | $0.01690 |
| Opus 5 | $0.00042 | $0.00845 |
| Sonnet 5 | $0.00017 | $0.00338 |
| Haiku 4.5 | $0.00008 | $0.00169 |
Grade A, and why
render-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 6d 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.
This is a copy
91% identical to render-postgres — 13 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.
How it starts
The opening of the file, as written. The whole thing — 137 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Render Managed PostgreSQL
This skill covers Managed Postgres on Render: how to connect, what cannot change after creation, storage behavior, limits, HA, replicas, and safe deletion. Deep dives live under references/.
When to Use
Apply this skill when the user:
- Configures Postgres for an app on Render (URLs, TLS, pooling)
- Creates or changes a database, plan, disk, or replicas
- Asks about backups, PITR, exports, or deleting a database
- Hits connection limits, SSL errors, or latency between services and DB
- Authors Blueprint
databases/readReplicasor wiresfromDatabase
For deploy flows and Blueprint basics, see render-deploy and render-blueprints. For private networking between services, see render-networking. For env var patterns, see render-env-vars.
Connection Patterns
Render exposes two connection URLs for the same logical database:
| URL | Use when | TLS |
|---|---|---|
| Internal | App or service on Render in the same region and workspace | Not required (private network) |
| External | Local development, CI, or tools outside Render | Required (TLS 1.2+) |
Always prefer the internal URL for Render-hosted apps so traffic stays on Render’s network and avoids extra latency and public egress patterns.
- IP allow list applies to external access only. Same-region Render services use the internal URL regardless of the allow list.
- External clients must use TLS; misconfigured clients often show SSL handshake or
sslmodeerrors.
URL formats, Dashboard locations, Blueprint fromDatabase, pooling, and common mistakes: references/connection-guide.md.
Creation and Setup
- Instance display name: Can be changed later (where the Dashboard allows renaming the resource).
- Immutable after creation:
databaseName, database user, region, PostgreSQL major version. Plan these before create; changing them requires a new database and migration. - Storage size: 1 GB or multiples of 5 GB when provisioning.
What ships with it
4 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.

render-postgres is a skill published in the GitHub repository cass-2003/local-workflow-skill (12 stars, last pushed 2mo ago), licensed MIT. It adds 83 tokens to every session and 1,690 once invoked, about $0.0004 per session on Opus 5. A static security scan graded it A with 0 findings. It is 91% identical to render-postgres, differing in 13 lines, and is treated as a copy.
