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.
npx agentmods add instructions/trsdn/mcp-server-ppt/testing-strategygit clone --depth 1 https://github.com/trsdn/mcp-server-pptWhat 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 | $0.01734 | $0.01734 |
| Opus 5 | $0.00867 | $0.00867 |
| Sonnet 5 | $0.00347 | $0.00347 |
| Haiku 4.5 | $0.00173 | $0.00173 |
Grade A, and why
mcp-server-ppt testing-strategy.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.
How it starts
The opening of the file, as written. The whole thing — 203 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Testing Strategy - Quick Reference
Test Execution
⚠️ CRITICAL: Always specify the test project explicitly to avoid running all test projects!
Core.Tests (Business Logic)
# Development (fast - excludes VBA and Screenshot)
dotnet test tests/PptMcp.Core.Tests/PptMcp.Core.Tests.csproj --filter "Category=Integration&RunType!=OnDemand&Feature!=VBA&Feature!=VBATrust&Feature!=Screenshot"
# Diagnostic tests (validate patterns, slow ~20s each)
dotnet test tests/PptMcp.Diagnostics.Tests/PptMcp.Diagnostics.Tests.csproj --filter "RunType=OnDemand&Layer=Diagnostics"
# VBA tests (manual only - requires VBA trust)
dotnet test tests/PptMcp.Core.Tests/PptMcp.Core.Tests.csproj --filter "(Feature=VBA|Feature=VBATrust)&RunType!=OnDemand"
# Screenshot tests (isolated run only - clipboard contention when parallel)
dotnet test tests/PptMcp.Core.Tests/PptMcp.Core.Tests.csproj --filter "Feature=Screenshot"
# Specific feature
dotnet test tests/PptMcp.Core.Tests/PptMcp.Core.Tests.csproj --filter "Feature=Slide"
ComInterop.Tests (Session/Batch Infrastructure)
# Session/batch changes (MANDATORY - see CRITICAL-RULES.md Rule 3)
dotnet test tests/PptMcp.ComInterop.Tests/PptMcp.ComInterop.Tests.csproj --filter "RunType=OnDemand"
McpServer.Tests (End-to-End Tool Tests)
# All MCP tool tests
dotnet test tests/PptMcp.McpServer.Tests/PptMcp.McpServer.Tests.csproj
# Specific tool
dotnet test tests/PptMcp.McpServer.Tests/PptMcp.McpServer.Tests.csproj --filter "FullyQualifiedName~SlideTool"
CLI.Tests (Command-Line Interface)
# All CLI tests
dotnet test tests/PptMcp.CLI.Tests/PptMcp.CLI.Tests.csproj
# Specific command
dotnet test tests/PptMcp.CLI.Tests/PptMcp.CLI.Tests.csproj --filter "FullyQualifiedName~Slide"
Run Specific Test by Name
# Use full project path + filter
dotnet test tests/PptMcp.Core.Tests/PptMcp.Core.Tests.csproj --filter "FullyQualifiedName~TestMethodName"
Round-Trip Validation Pattern
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.

mcp-server-ppt testing-strategy.instructions.md is an instructions file published in the GitHub repository trsdn/mcp-server-ppt (36 stars, last pushed 8d ago), licensed MIT. It adds 1,734 tokens to every session, about $0.0087 per session on Opus 5. A static security scan graded it A with 0 findings. It comes from a forked repository.
