mcp-server-powerpoint: Instructions file for GitHub Copilot

.github/instructions/mcp-server-guide.instructions.md

mcp-server-powerpoint mcp-server-guide.instructions.md is an instructions file for GitHub Copilot from sbroenne/mcp-server-powerpoint. It costs 1,985 tokens per session, scanned A, original, MIT.

A development guide for an MCP server, a program that exposes actions for an AI assistant to call, in the PowerPointMcp project. It covers tool types, synchronous code, error handling, and rules for text shown to AI systems.

In plain words
What is it for?
Use it when adding or changing PowerPointMcp tools, deciding whether a tool is generated or hand-written, handling failures, and writing AI-facing descriptions.
Why use it?
It reduces mistakes caused by editing generated tools incorrectly, returning the wrong type, or putting unsuitable content into tool descriptions.

Instructions file for GitHub Copilot

Written for GitHub Copilot: a Copilot instructions file.

This is sbroenne/mcp-server-powerpoint's own configuration. It tells GitHub Copilot how to work on mcp-server-powerpoint 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 mcp-server-powerpoint configures →

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

mcp-server-powerpoint mcp-server-guide.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 20d 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 — 175 lines — stays where its author put it; the contents beside it link to each section on GitHub.

MCP Server Development Guide

Tool methods return the MCP SDK's Task<CallToolResult>. Results include both a text JSON block for existing clients and the same object as structured content. Generated tools declare an output schema derived from their Core result contracts. A cancellation token is injected by the SDK and forwarded through the service bridge; it is never advertised as a tool argument.

LLM-Facing Content Rules

NO EMOJIS in LLM-consumed content — never use emoji characters in:

  • Tool [Description(...)] attributes and XML /// <summary> comments — the MCP SDK extracts these into the tool schema an LLM reads directly.
  • skill files and any future MCP prompt content.

Use plain text markers: "IMPORTANT:", "WARNING:", "NOTE:", "CRITICAL:".

DO keep emojis in user-facing content: README.md, this repo's own governance docs, and other human-read documentation — humans appreciate visual aids; LLM tool schemas do not need them and they cost tokens for no benefit.

Two Kinds of Tools: Hand-Written vs. Generated

Most of the MCP tool surface is generated, not hand-written. Before editing anything under Tools/, know which kind you're touching:

  • Hand-written (PresentationTools.cs only): the single presentation MCP tool. It is action-dispatch like Excel's file tool, but stays hand-written because create/open/list/close need custom session-registry behavior and optional presentation_session_id.
  • Generated (everything else — slide, shape, textframe, table, notes, layout, master, animation, image, media, chart, smartart, export, pagesetup, accessibility, customshow): one action-dispatch tool per [ServiceCategory] Core domain, emitted by PowerPointMcp.Generators.Mcp from the Core interface's [ServiceCategory]/[McpTool] attributes and XML doc comments. Never hand-write a new tool class for one of these domains — add the operation to the Core interface (with XML docs) and the generator picks it up. Interfaces that declare [McpReadOnlyActions(...)] also get a {tool}_read MCP alias containing only those actions. The original tool remains intact, and the CLI keeps its existing command surface. See architecture-patterns.instructions.md's Command Pattern section for the Core-side attribute shape.

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.
