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.

SkillSpector: 1 finding, up to medium
These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →

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 | $0.00186 | $0.10745 |
| Opus 5.5 | $0.00074 | $0.04298 |
| Sonnet 5.5 | $0.00037 | $0.02149 |
| Haiku 4.5 | $0.00019 | $0.01074 |
Grade A, and why
devexpress-reports-aspnetcore 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 7d 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.

DevExpress ASP.NET Core Reporting — Viewer & Designer Integration
Integrates the DevExpress Web Document Viewer (read-only preview) and Web Report Designer (full end-user designer) into ASP.NET Core MVC and Razor Pages applications. The viewer renders reports in the browser via server-side document generation; the designer lets end-users create and save reports without developer involvement.
When to Use This Skill
- Add a Document Viewer to an ASP.NET Core application
- Add an End-User Report Designer to an ASP.NET Core application
- Configure Program.cs services and middleware for reporting
- Register reporting client assets — via direct
<script>/<link>tags (package.json+libman.json, the default for existing apps) or npm bundling (BuildBundlerMinifier+bundleconfig.json, for greenfield/demo projects) - Implement
ReportStorageWebExtensionorIReportProvider - Customize viewer/designer toolbar, tab panel, export options, parameter editors
- Configure security: authorization, CSRF protection, CSP nonce
- Deploy reporting to Linux or macOS (Skia renderer setup)
- Troubleshoot blank viewers, HTTP errors, or script loading failures
- Set up multi-server (web farm/garden) document storage
When Not to Use This Skill
- When you need to create reports programmatically (bands, controls, data binding, expressions, export) — use the
devexpress-reports-coreskill or thedevexpress-visual-studio-rider-report-designskill and call a separate subagent instead. - When you need to integrate reporting into non-ASP.NET Core applications (e.g., ASP.NET MVC, ASP.NET Web Forms, WinForms, WPF, Angular, React, Vue) — use the appropriate platform-specific skill.
Component Overview
| Component | Infrastructure controllers (inherited) | Page-serving action | Storage | Client assets |
|---|---|---|---|---|
| Document Viewer (read-only) | 1 — WebDocumentViewerController |
required, e.g. ReportsController.Viewer() |
Optional (IReportProvider for name-based binding) |
Viewer set: dx.all.js + analytics-core + dx-webdocumentviewer (+ their CSS) |
| End-User Report Designer | 3 — adds ReportDesignerController + QueryBuilderController |
required, e.g. ReportsController.Designer() |
Required — ReportStorageWebExtension for save/load/open |
Designer superset: the viewer set plus dx-querybuilder + dx-reportdesigner + ace-builds — loaded once on the page |
| Standalone Parameters Panel (no preview) | 1 — WebDocumentViewerController (shared; no Viewer page) |
required, builds ReportParametersPanelModel |
Optional — same rule as the Viewer: needed only for name-based binding (see references/standalone-parameters-panel.md) | same as the Viewer set |

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-reports-aspnetcore is a skill published in the GitHub repository DevExpress/agent-skills (66 stars, last pushed 7d ago), licensed MIT. It adds 186 tokens to every session and 10,745 once invoked, about $0.0007 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 2026-08-30.
