What is elc-partnership-builder CLAUDE.md?

A project instruction file for an Engineering Leaders Community partnership service. It documents the service, its five partnership tools, its TypeScript and Cloudflare setup, and commands for running, building, deploying, and testing it.

Use it when developing or maintaining the partnership service, including local development, type checks, tests, and deployment.

It gives coding agents the project context and operating commands needed to work on the repository consistently.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00928	$0.00928
Opus 5	$0.00464	$0.00464
Sonnet 5	$0.00186	$0.00186
Haiku 4.5	$0.00093	$0.00093

Security

Grade A, and why

elc-partnership-builder CLAUDE.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 7d 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.

What this is

The Partnership AI Builder for the elc stream: an authless MCP server at https://www.engineeringleaders.io/mcp/partnership plus the chat backend for the /partner/chat/ widget on elc-web. Eleven tools: get_started (routes a greeting/test/unclear message to the right tool below), get_partnership_options, match_package, customize_package, book_intro_call, fit_to_budget, build_business_case, design_journey, request_offer — price a partnership from the published catalog with a 16% AI-channel discount — plus get_reach_options and quote_reach_combo (2026-09-03), the one-off menu behind engineeringleaders.io/reach: single items bought once, combo discount by item count, no AI-channel percentage. Registered on the MCP Registry and Smithery.

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.
