.agents/skills/embedding-mcp-assistants/SKILL.md

embedding-mcp-assistants is a skill for Claude Code, Codex from Cyruskraad/codex-claude-mcp. It costs 33 tokens per session (387 once invoked), scanned A, original, MIT.

A guide for placing a Noodle assistant inside an existing web or SaaS application. It covers the browser, user identity, sessions, and credential boundaries.

In plain words
What is it for?
Use it to mount an assistant in a web app, exchange sessions, configure its browser experience, and verify the requested local or hosted setup.
Why use it?
It helps keep the embedded assistant’s identity and credentials separate from the application’s business backends.

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

embedding-mcp-assistants 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 10d 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 it actually says

embedding-mcp-assistants

Deliver the requested assistant embed with identity and credential separation proven at the tested level.

Use when

  • Embed the Noodle assistant in an existing web app.
  • Wire browser mounting and session exchange.

Do not use when

  • Do not use to build a standalone MCP App.
  • Do not use when the request is only server authoring or deployment.

Required inputs

  • Application origin and mounting point.
  • Desired built-in or custom browser experience.
  • Identity/session boundary.
  • Requested local or hosted evidence level.

Workflow

Read and follow the canonical playbook references/embedded-assistant.md at ../noodle-seed/references/embedded-assistant.md. It owns the workflow; do not recreate it here or load the command catalog speculatively. Load references/authoring-workflow.md at ../noodle-seed/references/authoring-workflow.md only when the playbook or observed evidence names that concern.

Verification evidence

The embed works at the requested boundary without forwarding inbound credentials to business backends.

Recovery paths

Localize failures to origin, session exchange, browser mount, MCP surface, or hosted configuration.

Stop conditions

Stop when unavailable identity, origin, or hosted authority blocks the next evidence layer.

Handoff contract

Pass the selected outcome, explicit target, changed files, commands run, passing evidence, first unproven evidence layer, sanitized failure, remaining authority, and exact next action. The receiving skill continues from that layer; do not restart discovery or discard prior proof.

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.
