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 | $0.00030 | $0.02037 |
| Opus 5 | $0.00015 | $0.01019 |
| Sonnet 5 | $0.00006 | $0.00407 |
| Haiku 4.5 | $0.00003 | $0.00204 |
Grade A, and why
subscription-management 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 12d 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.

The opening of the file, as written. The whole thing — 157 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Subscription Management
Purpose
Every SaaS subscription the company pays for must be tracked — who uses it, when it renews, what it costs, and whether it's still worth it. This skill eliminates zombie subscriptions, right-sizes plans, times renewals strategically, and keeps the SaaS stack lean. Without it, companies waste 30% or more of their SaaS spend on unused or underused tools.
When to Use
- "Audit our SaaS subscriptions"
- "What subscriptions do we have / when do they renew?"
- "Optimize our tool stack / find unused subscriptions"
- "Review this renewal / negotiate this contract"
- "Consolidate overlapping tools"
Inputs Required
- Subscription inventory — source from: accounting system (QuickBooks/Xero), corporate card exports, bank statements, email invoices, SSO/procurement tools (Vendr, Tropic, Zylo).
- Usage data — login frequency per user, seat utilization, feature adoption. Either from the vendor's admin panel or from SSO logs.
- Contract terms — renewal date, term length, auto-renewal clause, cancellation window, price lock.
Quick Reference
| Metric / Action | Definition | Why It Matters |
|---|---|---|
| Seat Utilization | Active users / Paid seats. < 70% → flag for downsizing | Paying for seats nobody uses is the #1 SaaS waste |
| Cost per Seat | Annual subscription cost / Total seats | Compare against industry benchmarks for the tool category |
| Zombie Subscription | No active users in 60+ days, no critical dependency | Immediate cancellation candidate |
| Renewal Calendar | 12-month forward view of all renewals with action deadlines | Prevents auto-renewal surprises and missed negotiation windows |
| 80/20 Rule | 20% of subscriptions drive 80% of spend | Focus optimization energy on the expensive tools |
| Annual vs Monthly | Annual billing saves 15-20% on average | Switch to annual for tools you'll definitely use for a year |
Procedure
1. Build the Subscription Inventory
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.

subscription-management is a skill published in the GitHub repository gokulb20/crewm8-cfo-skills (2 stars, last pushed 4mo ago), licensed MIT. It adds 30 tokens to every session and 2,037 once invoked, about $0.0002 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.
