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.

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 | $0.00692 | $0.00692 |
| Opus 5 | $0.00346 | $0.00346 |
| Sonnet 5 | $0.00138 | $0.00138 |
| Haiku 4.5 | $0.00069 | $0.00069 |
Grade A, and why
Agent365-nodejs 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 yesterday.
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 — 98 lines — stays where its author put it; the contents beside it link to each section on GitHub.

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
.js,.ts,.jsx,.tsxfiles in the repository
Rule 2: Verify Copyright Headers
- Description: Ensure all JavaScript and TypeScript 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 imports or code
- Maintain proper formatting and spacing
Required Copyright Header Format
// Copyright (c) Microsoft Corporation.
// Licensed under the MIT License.
Or for multi-line format:
/**
* Copyright (c) Microsoft Corporation.
* Licensed under the MIT License.
*/
Implementation Guidelines
When Reviewing Code:
-
Kairo Check:
- Search for case-insensitive matches of "Kairo"
- Review context to determine if it's:
- A variable name
- A comment reference
- An import statement
- A string literal
- A type definition
- Suggest appropriate alternatives based on the context
-
Header Check:
- Verify the first non-empty, non-shebang lines of source files
- If missing, prepend the copyright header
- Ensure there's a blank line after the header before other content
- Do not add headers to:
index.jsorindex.tsfiles that are intentionally empty barrel exports- Generated files (if marked as such)
- Declaration files (
.d.ts) that are auto-generated
Example of Proper File Structure (JavaScript/TypeScript):
// Copyright (c) Microsoft Corporation.
// Licensed under the MIT License.
import { Something } from './something';
import * as fs from 'fs';
/**
* Class documentation
*/
export class MyClass {
// Rest of the code...
}
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.
