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 | $0.00081 | $0.02855 |
| Opus 5.5 | $0.00032 | $0.01142 |
| Sonnet 5.5 | $0.00016 | $0.00571 |
| Haiku 4.5 | $0.00008 | $0.00285 |
Grade A, and why
workday scanned grade A with 1 finding 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 20d 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.

Not a fault in itself. Listed so you know the mod talks to something, and to what.

The opening of the file, as written. The whole thing — 201 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Workday (via Apideck)
Access Workday through Apideck's Accounting, HRIS, ATS unified API — one of 34 Accounting connectors that share the same method surface. Code you write here ports to Access Financials, Acumatica, banqUP and 30 other Accounting connectors by changing a single serviceId string. Apideck handles auth, pagination, rate limiting, and retries so you don't write per-tenant Workday plumbing.

At a glance
- Implementation difficulty: highly complex — Custom Auth + Manual Per-Consumer Setup + Complex Permissions
- Vendor partnership required: no (Workday Partner Program) — Apideck holds the Workday partnership; joining the Workday Partner Program yourself is optional.
- Apideck-managed credentials: not available — Authentication is per consumer rather than per application, so there are no app-level credentials for Apideck to provide.
- Account type required: Workday tenant with Web Services access
- Consumer access level: Administrator with privileges to create Integration System Users and manage security groups and domain security policies
- Sandbox: not available — Testing runs against a consumer's own Workday tenant — no free trial, and Development tenants are contract-gated to existing Workday customers.
- Costs: No additional platform fees from Workday.
- Rate limits: No published hard limits; Workday throttles under high tenant load.
- Authentication: A per-consumer Integration System User (ISU); not OAuth.
- Webhooks: Virtual webhooks — no native webhooks in Workday; Apideck polls employees, applicants, jobs, bills, suppliers, purchase orders, and customers.
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 is a skill published in the GitHub repository apideck-libraries/api-skills (5 stars, last pushed yesterday), licensed Apache-2.0. It adds 81 tokens to every session and 2,855 once invoked, about $0.0003 per session on Opus 5.5. A static security scan graded it A with 1 finding (makes network calls).
