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 | $0.00065 | $0.02059 |
| Opus 5 | $0.00032 | $0.01030 |
| Sonnet 5 | $0.00013 | $0.00412 |
| Haiku 4.5 | $0.00006 | $0.00206 |
Grade A, and why
s3-storage-operations 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 9d 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.

Not a fault in itself. Listed so you know the mod talks to something, and to what.
**Architecture change (v2.0)**: S3 operations have been migrated from a built-in tool to HTTP REST API endpoints, callable via curl from any environment. Claude Code's Global Skill (`desirecore-s3-storage`) contains the How it starts

s3-storage-operations Skill
L0: One-line Summary
Lets the Agent operate S3-compatible object storage through the DesireCore HTTP API — uploading, downloading, listing, and deleting files, and generating shareable download links.
L1: Overview and Use Cases
Capability Description
s3-storage-operations is a Tool-Skill that interacts with the user's pre-configured S3-compatible object storage (AWS S3, Qiniu Kodo, MinIO, etc.) via the DesireCore Agent Service HTTP API.
Architecture change (v2.0): S3 operations have been migrated from a built-in tool to HTTP REST API endpoints, callable via curl from any environment. Claude Code's Global Skill (desirecore-s3-storage) contains the full curl invocation guide.
Core principle: the user's S3 connection is pre-configured under Resources → Object Storage. The API resolves the connection automatically — the Agent does not need to worry about connection details and can focus on the operation itself.
Use Cases
- The user asks to "upload a file", "put it in storage", or "save to S3"
- The user asks for "a download link", "share this file", or "download from S3"
- The user asks to "see what's in storage" or "list files in the bucket"
- The user asks to "delete from S3" or "clean up temp files"
- A workflow produces files (reports, exports, images) that need to be shared via URL
- The Agent needs to read data stored in S3 for further processing

What ships with it
2 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.

s3-storage-operations is a skill published in the GitHub repository desirecore/market (2 stars, last pushed yesterday), licensed MIT. It adds 65 tokens to every session and 2,059 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it A with 1 finding (makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
