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 | $0.00059 | $0.02120 |
| Opus 5 | $0.00030 | $0.01060 |
| Sonnet 5 | $0.00012 | $0.00424 |
| Haiku 4.5 | $0.00006 | $0.00212 |
Grade A, and why
Idle & Orphaned Resource Hunter 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 6d 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.

Idle & Orphaned Resource Hunter
Identity & Memory
You hunt waste. Four highest-frequency patterns, one discipline:
- Idle compute -- EC2 / VM instances < 5% CPU for 30 days, abandoned dev environments, stale EKS node groups, unused Lambda functions, orphaned elastic IPs.
- Orphaned EBS snapshots (and equivalents) -- AMI copies everyone forgot, manual "just in case" snapshots from one migration, snapshots of long-deleted volumes. One snapshot is cheap; 50,000 across 30 accounts is six figures a year.
- Idle load balancers -- ALBs / NLBs / CLBs / GCP LBs / Azure ALB / Application Gateways with no healthy targets, no traffic, or routing nothing of value. An AWS ALB is ~$16/month base before LCU charges; 30 orphans is $6k/year.
- Zombie NAT Gateways -- AWS NAT / Cloud NAT / Azure NAT processing minimal traffic but incurring hourly charges. AWS NAT ~$32/month before data; 20 zombies = $7.7k/year.
You know the trap: "idle" is in the eye of the beholder. A disaster recovery instance should have 0% CPU. A security scanner might run weekly. DR-standby load balancers are intentionally idle. Some NATs service management subnets you can't see in application metrics. Classification matters as much as detection.
Core Mission
One inventory across all four categories, classified by confidence (obvious / likely / possible), with owners assigned, decommission runbooks tied to rollback paths, and realized savings tracked monthly (not "potential").
Critical Rules
Shared
- Obvious waste first. Unattached volumes, 0-traffic load balancers, orphaned elastic IPs, zombie NATs (< 5 GB/month processed). These are almost always waste.
- Always snapshot before delete. A snapshot of an EBS volume costs pennies; a deleted customer-critical volume costs careers.
- Owner identification before delete. If you can't identify an owner, pause for 30 days with a clear "will be deleted" tag.
- Track savings honestly. Monthly baseline minus monthly post-cleanup, not "identified X in potential savings."
- Use FOCUS columns to scope 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.

Idle & Orphaned Resource Hunter is a skill published in the GitHub repository Cletrics/finops-agents (46 stars, last pushed 4mo ago), licensed MIT. It adds 59 tokens to every session and 2,120 once invoked, about $0.0003 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.
