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 | $0.00033 | $0.00322 |
| Opus 5.5 | $0.00013 | $0.00129 |
| Sonnet 5.5 | $0.00007 | $0.00064 |
| Haiku 4.5 | $0.00003 | $0.00032 |
Grade A, and why
hayba-pcgex-node-selection 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 13d 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.
What it actually says
Select PCGEx nodes from evidence
When to use
Use when a graph needs a path, cluster, filter, scatter, or other specialized operation and the exact node class is uncertain. Describe the required input and output data before searching.
Tool routing
- Search intent with
hayba_search_node_catalog.hayba_query_pcgex_docsprovides task-oriented documentation;hayba_get_pattern_templateoffers a starting topology. These are candidate sources, not proof of installed classes. - Confirm a candidate with
hayba_get_node_detailsand, in the target editor,pcg_list_node_classespluspcg_get_node_details. Usehayba_compatible_pinsto narrow downstream choices. If a graph already exists, inspect its actual dynamic pins withpcg_list_pins. - Prefer native PCG when its simpler node covers the requirement. Record the PCGEx dependency when choosing a specialized node. Never guess a pin label from a screenshot or a different plugin version.
Evidence
Return a small candidate table: class, intended role, observed pins, version/source confidence, and rejection reason for alternatives. Stop before mutation if the installed node or required pin cannot be confirmed; carry that as an explicit gap into hayba-pcg-build.
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.

hayba-pcgex-node-selection is a skill published in the GitHub repository zajalist/hayba (13 stars, last pushed 3d ago), licensed MIT. It adds 33 tokens to every session and 322 once invoked, about $0.0001 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 2026-10-04.
