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 | $0.00129 | $0.04323 |
| Opus 5 | $0.00064 | $0.02161 |
| Sonnet 5 | $0.00026 | $0.00865 |
| Haiku 4.5 | $0.00013 | $0.00432 |
Grade A, and why
devexpress-office-file-api-zip 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 11d 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 — 446 lines — stays where its author put it; the contents beside it link to each section on GitHub.
DevExpress Zip Compression and Archive API
The Zip Compression and Archive API is a non-visual .NET library for creating, reading, and extracting ZIP archives programmatically — without any external dependencies. It supports archiving files, directories, streams, byte arrays, and text; password-protecting entries with AES-256 or ZipCrypto; filtering content during archiving; cancellation via progress callbacks; and conflict resolution during extraction.
When to Use This Skill
Use this skill when you need to:
- Create a ZIP archive from a directory (recursively) or from a list of files
- Add individual files to a new or existing ZIP archive
- Filter files during archiving using the
ItemAddingevent - Archive a .NET
Streamor abyte[]directly (without writing to disk first) - Archive a text string as a named entry in a ZIP file
- Password-protect archive entries using AES-256 (
EncryptionType.Aes256) or ZipCrypto (EncryptionType.PkZip) - Add comments to individual archive entries
- Extract (unzip) an archive to a directory
- Resolve file conflicts during extraction with a callback (
AllowFileOverwriteevent) - Cancel a long-running archiving operation via the
Progressevent - Handle archiving errors without aborting the entire operation
- Add files to an existing archive without losing its current contents
Prerequisites & Installation
NuGet Packages
| Package | Purpose |
|---|---|
DevExpress.Document.Processor |
Core ZIP compression and archive functionality |
.NET (8/9/10+)
dotnet add package DevExpress.Document.Processor
.NET Framework (4.6.2+)
Install-Package DevExpress.Document.Processor
Or add a reference to DevExpress.Docs.v26.1.dll directly.
Important: All DevExpress packages in a project must share the same version number. A valid DevExpress license is required.
Package Versions
Unless the user explicitly requests a specific version, always target the latest DevExpress release (v26.1 at the time of writing). dotnet add package <PackageName> without --version installs the latest stable version — prefer this form. Never pin an older version in project files, Dockerfiles, or CI/CD pipelines unless the user asks for it. This is especially important in integration scenarios (Docker, cloud deployments). All DevExpress.* packages in a project must share the same version.
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.

devexpress-office-file-api-zip is a skill published in the GitHub repository DevExpress/agent-skills (52 stars, last pushed 24d ago), licensed MIT. It adds 129 tokens to every session and 4,323 once invoked, about $0.0006 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 2026-08-30.
