dsh-vision-router: Instructions file for GitHub Copilot

.github/instructions/runtime-security.instructions.md

dsh-vision-router runtime-security.instructions.md is an instructions file for GitHub Copilot from ysr666/dsh-vision-router. It costs 184 tokens per session, scanned A, original, MIT.

A set of security review rules for runtime code in the dsh-vision-router project. Runtime code is the part of a program that handles live inputs, events, services, files, and network operations.

In plain words
What is it for?
Use it when reviewing code that handles provider responses, model output, files, URLs, attachments, sessions, subprocesses, or network data. It guides checks for limits, cancellation, authority, caching, and diagnostics.
Why use it?
It helps reviewers catch malformed input, unbounded work, stale results after cancellation, incorrect session ownership, and accidental exposure of credentials.

Instructions file for GitHub Copilot

Written for GitHub Copilot: a Copilot instructions file.

This is ysr666/dsh-vision-router's own configuration. It tells GitHub Copilot how to work on dsh-vision-router itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything dsh-vision-router configures →

About the project

dsh-vision-router is a plugin that lets text-based DeepSeek Harness agents inspect images through a built-in vision service and image-analysis tools. Agents use it for tasks such as answering questions about images, locating elements, reading text, comparing pixels, and tracing or extracting visual content. The catalogue entries support using the plugin within DeepSeek Harness workflows.

Token cost

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.

Security

Grade A, and why

dsh-vision-router runtime-security.instructions.md 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 3d 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.

What it actually says

When reviewing runtime code, treat all Host services, settings documents, provider responses, attachment metadata, session events, model output, filesystem paths, URLs, MIME labels, and environment-derived values as potentially malformed.

Require explicit bounds for bytes, counts, retries, recursion/depth, timers, queues, caches, screenshots, image dimensions, subprocess work, and network bodies where applicable.

Cancellation must prevent stale publication even when the underlying Host operation cannot be physically cancelled. Session/attachment/model authority must remain scoped to the correct DSH context and session.

Credential values and deterministic hashes derived from credential values must not become durable cache identity or diagnostic output when a non-secret identity/event can provide the same invalidation semantics.

Do not infer DSH capabilities from version strings when a capability seam exists. Exact preview verification evidence is not a public support promise.

Changes

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.
