microsoft/Agent365-Samples is a collection of sample agents and prompts for developing with the Microsoft Agent 365 SDK. It is for developers building agents for Microsoft 365, Teams, Copilot Studio, Webchat, and related development environments in several programming languages. The catalogue entries are examples and instructions built around these samples.

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 | $0.03602 | $0.03602 |
| Opus 5.5 | $0.01441 | $0.01441 |
| Sonnet 5.5 | $0.00720 | $0.00720 |
| Haiku 4.5 | $0.00360 | $0.00360 |
Grade A, and why
Agent365-Samples copilot-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 1mo 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

Code Review Rules
Rule 1: Check for "Kairo" Keyword
- Description: Scan code for any occurrence of the keyword "Kairo"
- Action: If "Kairo" is found in any code file:
- Flag it for review
- Suggest removal or replacement with appropriate terminology
- Check if it's a legacy reference that needs to be updated
- Files to check: All source files (
.cs,.csx,.py,.js,.ts,.mjs) in the repository
Rule 2: Verify Copyright Headers
- Description: Ensure all source code files have proper Microsoft copyright headers
- Action: If a source file is missing a copyright header:
- Add the Microsoft copyright header at the top of the file
- The header should be placed before any using/import statements or code
- Maintain proper formatting and spacing
- Use language-appropriate comment syntax
Required Copyright Header Format

Implementation Guidelines
When Reviewing Code:
-
Kairo Check:
- Search for case-insensitive matches of "Kairo"
- Review context to determine if it's:
- A class name
- A namespace
- A variable name
- A comment reference
- A using statement
- A string literal
- Suggest appropriate alternatives based on the context
-
Header Check:
- Verify the first non-empty lines of source files
- If missing, prepend the copyright header with appropriate comment syntax
- Ensure there's a blank line after the header before other content
- Do not add headers to:
- Auto-generated files:
- C#: Marked with
<auto-generated>or// <auto-generated />,.Designer.cs,.g.cs - Python: Files with auto-generated markers
- JavaScript/TypeScript:
.d.tstype definitions, files with@generatedmarker
- C#: Marked with
- Files with

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.
