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 | $0.00025 | $0.00526 |
| Opus 5 | $0.00013 | $0.00263 |
| Sonnet 5 | $0.00005 | $0.00105 |
| Haiku 4.5 | $0.00003 | $0.00053 |
Grade A, and why
marketplace-invoke 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 5d 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 — 56 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Marketplace Invoke
The caller supplies only the provider-neutral vendor request body and bounded transport preferences. Paid-listing admission injects the immutable offer and the run idempotency identity. The selected settlement adapter derives its own protocol envelope, authority attenuation, endpoint, amount, and parent binding; neither callers nor product facades may forge those fields.
marketplace-invoke is the buyer-facing marketplace skill called through the
existing runx skill surface. Paid listing
admission injects the immutable listing, vendor, exact endpoint, vendor price,
demand-side fee, settlement family, and expected receipt class into one Runx
run before its quote is fingerprinted. Hosted receipt custody verifies the
returned inner receipt and seals the outer execution as a mediated composite
receipt.
The skill is rail-neutral at its boundary. settlement_family selects an
explicit adapter branch; x402 is the first implementation. Stripe and future
rails add sibling branches while preserving the listing, vendor, authority,
result, and composite-receipt semantics. Provider SDKs, wallets, credentials,
settlement recovery, and database state remain in Runx Hosted.

Operator guide
Use this skill through a paid endpoint listing after marketplace discovery.
Supply the exact vendor invocation body and optional bounded transport limits.
marketplace_offer and idempotency_seed are reserved for hosted admission;
caller-supplied values are refused. Keep large inputs behind artifact references.
The x402 branch delegates settlement and each read observation to x402-pay.
marketplace-invoke emits the existing current-V1 external-job schedule intent
after settlement, then its package-owned vendor-readback runner performs one
read per durable claim until the vendor receipt is ready or the bounded deadline
ends. This skill adds no wrapper approval: the delegated settlement is the one
waiting-resolution gate for vendor spend. The skill never interprets wallet
material.
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.

marketplace-invoke is a skill published in the GitHub repository runxhq/runx (84 stars, last pushed today), licensed Apache-2.0. It adds 25 tokens to every session and 526 once invoked, about $0.0001 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 2026-09-03.
