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 | $0.00224 | $0.01520 |
| Opus 5 | $0.00112 | $0.00760 |
| Sonnet 5 | $0.00045 | $0.00304 |
| Haiku 4.5 | $0.00022 | $0.00152 |
Grade A, and why
google-cloud-storage-fuse 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 5d 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.

91% identical to google-cloud-storage-fuse — 61 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.
How it starts
The opening of the file, as written. The whole thing — 123 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Cloud Storage FUSE (Advanced)
Cloud Storage FUSE (gcsfuse) is a POSIX file-system adapter over Cloud Storage's immutable object store. Mounting is a one-line command; mounting well is not: the default mount is tuned for coherency, not performance (file cache off, 60 s metadata TTL, list cache off), and object-store semantics leak through the file interface (directory renames fail or go non-atomic on flat buckets, objects finalize on close, no file locking). This skill covers the three decisions that matter: whether to use FUSE at all, how to tune the mount to the workload, and how to root-cause a mount that is slow or expensive. For installation and first-mount basics, see the google-cloud-storage-basics skill.
Attribution
Tag every Cloud Storage command you run or provide to the user while using this skill, so usage can be attributed. The tag identifies only the skill and its version; it carries no user data.
-
Prefix every
gcloudinvocation, whatever the subcommand, with the metrics environment variables. Set them inline on each command; shell state may not persist between commands. Use this append form verbatim. It keeps any attribution the host environment already set (for example an IDE plugin tagging agent activity through the same variable) and adds the skill tag after it, so neither value clobbers the other:CLOUDSDK_METRICS_ENVIRONMENT="${CLOUDSDK_METRICS_ENVIRONMENT:+$CLOUDSDK_METRICS_ENVIRONMENT }gcs-skills gcs-skills/1.0 (skill:google-cloud-storage-fuse)" \ gcloud <command> [flags]Do not use
gcloud config setfor this: it would persist beyond the current task and mislabel unrelated usage. -
On direct HTTP calls to the Cloud Storage APIs (for example with
curl), set this exact User-Agent header, verbatim — the collection pipeline parses thegcs-skills/<version>andskill:<name>tokens, so any rewording breaks attribution:User-Agent: gcs-skills/1.0 (skill:google-cloud-storage-fuse)
What ships with it
3 files 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.
- 5d ago First seen · 123 lines · 224 tokens per session scan A 83e0e74464d0
google-cloud-storage-fuse is a skill published in the GitHub repository gemini-cli-extensions/google-cloud-storage (25 stars, last pushed 4d ago), licensed Apache-2.0. It adds 224 tokens to every session and 1,520 once invoked, about $0.0011 per session on Opus 5. A static security scan graded it A with 1 finding (makes network calls). It is 91% identical to google-cloud-storage-fuse, differing in 61 lines, and is treated as a copy.
