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.

What it costs to keep this loaded
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 | $0.00063 | $0.03005 |
| Opus 5.5 | $0.00025 | $0.01202 |
| Sonnet 5.5 | $0.00013 | $0.00601 |
| Haiku 4.5 | $0.00006 | $0.00300 |
Grade A, and why
polygres-data-pipeline 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.
How it starts
The opening of the file, as written. The whole thing — 265 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Polygres Data Pipeline
Turn setup intent into the smallest complete working result. Adapt to what the user actually needs. Do not force every setup through schema creation, embeddings, graph, backfill, continuous capture, retrieval code, or agent instructions.
Use guidance at the right strength
Treat this skill as a decision guide, not a mandatory architecture or ordered checklist. Adapt, reorder, replace, or omit recommended components and numeric defaults when inspected evidence or the user's outcome supports a better design. Numeric defaults are starting points, including sample sizes, result counts, token budgets, recall timing, capture timing, and model rankings.
Keep only safety and correctness boundaries firm: preserve authorization and provenance, keep secrets out of plans and payloads, disclose and approve material effects, use compatible embedding contracts, avoid unsupported public interfaces and invented graph relationships, and test the important selected path before calling it operational.
Choose the execution surface
When Polygres MCP tools are available, read
references/mcp-tool-contract.md, call whoami, and prefer discovered
compatible MCP tools for interactive inspection, setup, retrieval, and
operation tracking. Treat the connection's project boundary, feature selection,
read-only setting, and visible catalog as authoritative.
Use the existing CLI, SDK, Dashboard, or PostgreSQL workflow when MCP is absent, incompatible, or does not expose the required operation. Keep the SDK for persistent application code, the Dashboard for source secret entry and import start, and the CLI for migrations, Runtime keys, and other documented operator workflows.
Recognize setup intent
Activate for broad prompts such as "Help me set up Polygres," contextual prompts such as "look at my conversations and set up Polygres," and detailed technical specifications. Treat examples as illustrations, not required wording.

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.

polygres-data-pipeline is a skill published in the GitHub repository Evokoa/polygres-skills (10 stars, last pushed 1mo ago), licensed Apache-2.0. It adds 63 tokens to every session and 3,005 once invoked, about $0.0003 per session on Opus 5.5. 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.
