What is building-chat-interfaces?

A development guide for building AI chat interfaces with custom backends, user login, and added user or page context. It covers ChatKit components and authentication patterns for MCP, a standard way for AI systems to connect to tools.

Use it when adding an AI chat UI, connecting a custom backend, implementing authentication, injecting context, or using httpOnly cookie proxies.

It helps solve the implementation details around connecting a chat interface to an AI agent, protecting access, and safely passing context through the application.

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	$0.00073	$0.02207
Opus 5.5	$0.00029	$0.00883
Sonnet 5.5	$0.00015	$0.00441
Haiku 4.5	$0.00007	$0.00221

Measured 2mo ago against content hash b938d802e36e, method: parsed. Prices are Anthropic first-party input rates as of 2026-10-07, from the pricing page.

Security

Grade A, and why

building-chat-interfaces scanned grade A with 1 finding 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.

The scan reads SKILL.md. This mod also ships 1 executable file (scripts/verify.py), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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.

Not a fault in itself. Listed so you know the mod talks to something, and to what.

What ships with it

3 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

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.
