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 rules/titanzero/outlook-mcp/generalgit clone --depth 1 https://github.com/titanzero/outlook-mcpWhat 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 | $0.00211 | $0.00211 |
| Opus 5 | $0.00105 | $0.00105 |
| Sonnet 5 | $0.00042 | $0.00042 |
| Haiku 4.5 | $0.00021 | $0.00021 |
Grade A, and why
general 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.
What it actually says
Core Conventions
- Use CommonJS (
require/module.exports) in plain JavaScript; do not use ESM. - Keep shared constants in
config.js; avoid hard-coded field lists, pagination, URLs, and timezone values. - Build MCP responses with
makeResponse()andmakeErrorResponse()fromutils/response-helpers.js. - Detect auth failures with
isAuthError(error)and return the auth message directly. - For data output, call
formatResponse(structuredData, textFallback)fromutils/response-formatter.js. - Log diagnostics with
console.error()(stdout is reserved for MCP protocol traffic).
Baseline Error Pattern
try {
// handler logic
} catch (error) {
if (isAuthError(error)) {
return makeErrorResponse(error.message);
}
return makeErrorResponse(`Error doing X: ${error.message}`);
}
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.

general is a cursor rule published in the GitHub repository titanzero/outlook-mcp (1 stars, last pushed 2mo ago), licensed MIT. It adds 211 tokens to every session, about $0.0011 per session on Opus 5. A static security scan graded it A with 0 findings. It comes from a forked repository.
