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 | $0.00123 | $0.00468 |
| Opus 5 | $0.00062 | $0.00234 |
| Sonnet 5 | $0.00025 | $0.00094 |
| Haiku 4.5 | $0.00012 | $0.00047 |
Grade A, and why
workday-reference 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 10d 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
Workday Integration Reference
This skill documents the Rossum-hosted Workday connector — the webhook service that
submits AP invoices to Workday via its SOAP API (Submit_Supplier_Invoice) and imports
Workday reference data (suppliers, POs, cost centers, tax objects, …) into Master Data
Hub datasets. Configuration is pure JSON in the hook's settings; no code is required.
For the full guide — wiring, the mapping DSL primitive by primitive, payload conventions, import operations, scheduling, and gotchas — see reference.md.
Use this knowledge when:
- Wiring or reviewing a Workday export or import hook
(
https://<org base>/svc/workday/api/v1/…, secrets, queue-based config selection) - Writing the export
mapping— field references, conditional blocks, line iteration, value switches, attachments - Projecting invoice lines onto Workday's goods vs service line model
(
Quantity×Unit_CostvsExtended_Amount) - Setting up master-data import —
Get_*operations, MDH datasets,replacevsupdate, differential sync, cron cadences - Debugging tenant connectivity — implementation vs production domains, ISU permissions, IP allowlists
Note: this pack covers the dedicated Workday SOAP connector. For REST/JSON export
targets (including Workday's REST procurement API called from a custom hook), see
export-pipeline-reference; for the datasets the import fills and the matching that
reads them, see mdh-reference.
What ships with it
1 file 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.

workday-reference is a skill published in the GitHub repository rossumai/claude-marketplace (5 stars, last pushed yesterday), licensed MIT. It adds 123 tokens to every session and 468 once invoked, about $0.0006 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 2026-08-31.
