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.

What it costs to keep this loaded
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 | $0.00000 | $0.00527 |
| Opus 5 | $0.00000 | $0.00264 |
| Sonnet 5 | $0.00000 | $0.00105 |
| Haiku 4.5 | $0.00000 | $0.00053 |
Grade A, and why
google-cloud-storage 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 8d 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.
How it starts
The opening of the file, as written. The whole thing — 59 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Google Cloud Storage API Skill
Quick Start
Google Cloud Storage (GCS) is the GCP equivalent of S3, optimized for high durability and tight integration with Google's ML and BigQuery ecosystems.
npm install @google-cloud/storage
Common Workflows
Signed URLs for Client Uploads
Never pass file buffers through your Node.js application. Generate a V4 Signed URL using @google-cloud/storage, send it to the frontend, and have the browser PUT the file directly into GCS.
Production Patterns
Resumable Uploads
For files exceeding 5MB, always utilize resumable uploads. The SDK handles this automatically via bucket.file().createWriteStream({ resumable: true }).
Error Recovery
Handle intermittent network failures during massive downloads by wrapping stream pipes in error handlers and relying on GCS's native retry capabilities built into the Node.js SDK.
Security Notes
Use Workload Identity Federation instead of downloading static JSON Service Account keys. Enforce Uniform Bucket-Level Access to prevent accidental public exposure via individual object ACLs.
Performance Considerations
If you are serving thousands of small images globally, place Cloud CDN in front of your GCS bucket. Do not serve highly-trafficked public assets directly from GCS storage nodes.
Testing Guidance
Use the Google Cloud Storage emulator (fs-test-server) to mock GCS APIs locally during CI without incurring egress charges.
Troubleshooting
If Signed URLs fail with 'SignatureDoesNotMatch', ensure the Content-Type header sent by the browser exactly matches the contentType specified when generating the URL.

Why use this skill
Use this when your agent works with google-cloud-storage — structured patterns beat pasted docs and prevent common hallucinations.
AI pitfalls
- Using outdated SDK or API versions from training data
- Inventing environment variable names
- Omitting error handling and retry logic
What ships with it
7 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.

google-cloud-storage is a skill published in the GitHub repository ashish7802/awesome-api-skills (13 stars, last pushed 8d ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 527 tokens. 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 2026-08-30.
