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 | $0.00009 | $0.00428 |
| Opus 5.5 | $0.00004 | $0.00171 |
| Sonnet 5.5 | $0.00002 | $0.00086 |
| Haiku 4.5 | $0.00001 | $0.00043 |
Grade A, and why
estimate-gcp-cost 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 1mo 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
Estimate GCP Cost
Context
- gcloud version: !
gcloud --version 2>&1 | head -1 || echo "gcloud not installed" - Current project: !
gcloud config get-value project 2>&1 || echo "No project set" - Billing account: !
gcloud billing accounts list --format="value(name)" 2>&1 | head -1 || echo "No billing account"
Your Task
Analyze GCP costs and provide optimization recommendations for the specified project.
Arguments
$1: Project ID (optional, uses current project if not provided)
Steps
-
Analyze current costs
- Query billing data from BigQuery export
- Group by service and resource type
- Identify top cost drivers
-
Get recommendations
- Query Recommender API for rightsizing
- Identify committed use discount opportunities
- Find unused resources
-
Provide optimization suggestions
- Committed use discounts
- Preemptible VM candidates
- Rightsizing recommendations
- Storage class optimization
- Unused resource cleanup
-
Calculate potential savings
- Estimate savings per recommendation
- Prioritize by impact
- Provide implementation commands

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.
- 1mo ago First seen · 72 lines · 9 tokens per session scan A 3959c101947d
estimate-gcp-cost is a command published in the GitHub repository armanzeroeight/fastagent-plugins (29 stars, last pushed 2mo ago), licensed MIT. It adds 9 tokens to every session and 428 once invoked, about $0.0000 per session on Opus 5.5. 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.
