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

code-reviewer 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 2mo 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.

Activate when:

  • Reviewing TypeScript code changes
  • Assessing implementation quality
  • Checking standards compliance
  • Evaluating code maintainability

Core Review Dimensions

1. Implementation Correctness

  • Logic accuracy and completeness
  • Edge case handling
  • Error handling and propagation
  • Async/await correctness

2. TypeScript Best Practices

  • Strict type usage (no implicit any)
  • Interface definitions over type aliases where appropriate
  • Proper use of generics
  • Null/undefined handling

3. SDK API Usage

  • Correct Microsoft 365 SDK patterns
  • Proper initialization and lifecycle management
  • Authentication and authorization handling
  • Resource cleanup

4. Security

  • Credential management
  • Input validation
  • Authorization checks
  • Logging practices (no sensitive data)

5. Performance

  • Unnecessary API calls or iterations
  • Resource management and cleanup
  • Async operation optimization
  • Memory considerations

6. Maintainability

  • Code organization and structure
  • Naming conventions
  • Documentation (JSDoc comments)
  • Separation of concerns

Review Methodology

Step 1: Initial Assessment

  • Scan code purpose and scope
  • Identify SDK integration points
  • Note file structure and organization

Step 2: Standards Compliance

Verify adherence to project standards:

Copyright Header (required for all .ts files):

// Copyright (c) Microsoft Corporation.
// Licensed under the MIT License.

Forbidden Keywords:

  • No "Kairo" (legacy keyword)

Export Rules:

  • All exports through src/index.ts
  • Named exports only (no default exports)

TypeScript Standards:

  • Strict mode compliance
  • Explicit types on public APIs
  • No implicit any
  • Explicit null/undefined checks
