Context enrichment for agentic AI application development using LangChain, Vercel AI SDK, and assistant-ui.

  • Works in 3 steps: Detect Framework Need → Synthesize Context → Deliver Enriched Context
  • Building AI agents
  • SKILL.md covers Persona, Interface, Constraints and References, plus 1 more section
  • Instructions only: no scripts, shell commands, URLs or credentials in SKILL.md

What it does

Agentic Patterns is an agent skill from rsmdt/the-startup. Context enrichment for agentic AI application development using LangChain, Vercel AI SDK, and assistant-ui. Use when building AI agents, chat interfaces, tool-calling pipelines, RAG systems, or multi-step AI workflows.

Its SKILL.md is about 500 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in AI & LLM Engineering, covering Building AI agents, Structured output and tool calling and Retrieval-augmented generation. It works with Vercel AI SDK and LangChain. The repository describes itself as: The Agentic Startup - A collection of Claude Code commands, skills, and agents. The licence is MIT.

When your agent uses it

  • Building AI agents
  • Chat interfaces
  • Tool-calling pipelines
  • Multi-step AI workflows

Example prompts

  • “/agentic-patterns”

Workflow steps

3 steps, taken from the step headings in SKILL.md.

  1. Detect Framework Need
  2. Synthesize Context
  3. Deliver Enriched Context

What it can do on your machine

Read from SKILL.md and the folder at commit 88d447c. 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

    No scripts in the folder and no shell commands in SKILL.md.

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    Links to these hosts (documentation or services it may open):

    • docs.langchain.com
    • ai-sdk.dev
    • assistant-ui.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

Agentic Patterns loads about 501 tokens when it runs. Until then it costs about 59 tokens; SKILL.md has 180 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~59
When it runs · the whole SKILL.md, loaded when a task matches
~501

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); files beside SKILL.md are not scanned.

Persona

Act as an agentic AI development specialist who enriches implementation context with current framework documentation and proven integration patterns.

Development Target: $ARGUMENTS

Interface

AgenticContext { frameworks: string[] pattern: AGENT | CHAT_UI | RAG | TOOL_CALLING | MULTI_STEP | EVALUATION }

State { target = $ARGUMENTS detectedFrameworks = [] }

Constraints

Always:

  • Detect which frameworks are relevant before fetching documentation.
  • Only fetch sources relevant to the development target.
  • Note breaking changes or version-specific behavior when found in docs.

Never:

  • Assume API signatures without consulting current documentation.
  • Recommend framework features without verifying they exist in current docs.

References

  • LangChain — Agent orchestration, LangGraph workflows, chains, evaluations, LangSmith observability
  • Vercel AI SDK — Streaming AI UI, tool calling, RAG, multi-modal, React hooks, server actions
  • assistant-ui — React chat UI components, runtime integrations, thread management, attachments

Workflow

1. Detect Framework Need

Identify which frameworks are relevant from the development target. Fetch the corresponding reference documentation.

2. Synthesize Context

Combine fetched documentation into actionable guidance:

  • Framework capabilities that match the target pattern.
  • Cross-framework integration patterns (e.g., AI SDK + assistant-ui runtime).
  • Recommended patterns and anti-patterns from current docs.
3. Deliver Enriched Context

Provide framework-specific guidance integrated with the development target.
