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 | $0.00100 | $0.03426 |
| Opus 5.5 | $0.00040 | $0.01370 |
| Sonnet 5.5 | $0.00020 | $0.00685 |
| Haiku 4.5 | $0.00010 | $0.00343 |
Grade A, and why
rgthree 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 2mo 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 — 222 lines — stays where its author put it; the contents beside it link to each section on GitHub.
rgthree-comfy
rgthree-comfy is one of the most widely installed packs, so its nodes turn up in a
large share of community workflows. Three of its properties make it a recurring
agent-failure mode — all three fail quietly enough to look like success.
The three things that catch agents out
1. Some rgthree nodes are FRONTEND-ONLY. They are registered by the pack's JS
(registerCustomNodes()), have no Python class, and are therefore absent from
/object_info by design. Checking /object_info and concluding "this node doesn't
exist" is wrong. /object_info lists 24 rgthree backend types; the toggles are not
among them.
2. They are configured through PROPERTIES, not widgets. matchTitle,
toggleRestriction and sort live in node.properties (right-click → Properties),
not in widgets. Use panel_set_property. panel_set_widget does not silently
half-work — it refuses, with has no widget "matchTitle" (available: …) listing
the widgets that do exist. That refusal is the fastest confirmation you are on the
properties path; read it rather than retrying the write.
3. Fast Groups nodes take NO wiring and enumerate GROUPS by title. Leave the
OPT_CONNECTION output unconnected. The node renders one toggle per matching group,
so the groups must exist and be named before the node is useful.
Which rgthree nodes panel_add_node will actually add
The panel authorizes every add against fresh /object_info and fails closed on a
type it cannot find. Genuinely frontend-only types are exempt only via an explicit
allowlist (FRONTEND_ONLY_NODE_TYPES), so the exemption covers seven rgthree
types and no others:

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.

rgthree is a skill published in the GitHub repository artokun/comfyui-mcp (897 stars, last pushed 3d ago), licensed MIT. It adds 100 tokens to every session and 3,426 once invoked, about $0.0004 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 2026-08-30.
