What it does
Building Chat Interfaces is an agent skill from aiskillstore/marketplace. Build AI chat interfaces with custom backends, authentication, and context injection. Use when integrating chat UI with AI agents, adding auth to chat, injecting user/page context, or implementing httpOnly cookie proxies. Covers ChatKitServer, useChatKit, and MCP auth patterns. NOT when building simple chatbots without persistence or custom agent integration.
Its SKILL.md is about 2.4k tokens, which your agent loads only when the skill is triggered. The skill folder holds 6 other files, including scripts and reference files (for example `references/chatkit-integration-patterns.md`, `references/nextjs-httponly-proxy.md` and `scripts/verify.py`).
It sits in Backend & APIs, covering Authentication, Chatbots and conversational support and MCP servers. It works with Model Context Protocol. The repository describes itself as: Security-audited skills for Claude, Codex & Claude Code. One-click install, quality verified.
When your agent uses it
- Integrating chat UI with AI agents
- Adding auth to chat
- Injecting user/page context
- Implementing httpOnly cookie proxies
Example prompts

Requirements
- Python 3
- Node.js
Workflow steps
6 steps, taken from the step headings in SKILL.md.
- ChatKit Server with Custom Agent
- Database Persistence
- JWT/JWKS Authentication
- Custom Fetch Interceptor
- Page Context Extraction
- Script Loading Detection
What it can do on your machine
Read from SKILL.md and the folder at commit 755bc35. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
Ships 1 file in scripts/ (Python), which the agent can run.
Shell commands in SKILL.md call:
uvnpmpython3
From the folder's file list and the shell code blocks in SKILL.md.
Network
Hosts in commands or code, which the agent is likely to contact:
cdn.platform.openai.com
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Building Chat Interfaces loads about 2.4k tokens when it runs, and up to ~5k if it reads all its reference files. Until then it costs about 97 tokens; SKILL.md has 221 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); the scripts in this folder are not scanned.
SKILL.md
Without a licence we can't republish the file, so here is its outline and opening line. It has 221 words (~2,384 tokens).
“Build production-grade AI chat interfaces with custom backend integration.”
