assistant-presets

assistant-presets is a skill for Claude Code from itallstartedwithaidea/agent-skills. It costs 26 tokens per session (1,499 once invoked), scanned A, original, MIT.

A framework for creating specialized AI assistant configurations called presets. A preset defines an assistant’s role, instructions, model settings, available tools, response format, and quality checks.

In plain words
What is it for?
Use it to build, version, test, and deploy assistants such as contract reviewers, medical triage helpers, code reviewers, or customer-support agents.
Why use it?
It provides a repeatable way to turn a general-purpose AI model into an assistant for a particular domain or workflow and to test whether it behaves as intended.

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

assistant-presets 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 8d 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.

Assistant Presets

Part of Agent Skills™ by googleadsagent.ai™

Description

Assistant Presets provides a framework for creating, testing, and deploying specialized AI assistant configurations for domain-specific tasks. Each preset encapsulates a system prompt, model parameters, tool access permissions, output format constraints, and quality benchmarks into a reusable, versionable artifact that transforms a general-purpose LLM into a domain expert.

A bare LLM is a generalist. A well-crafted preset turns it into a specialist: a legal contract reviewer that flags liability clauses, a medical triage assistant that follows diagnostic protocols, a code reviewer that enforces team conventions, or a customer support agent that follows the company's tone guide. The difference between a useful AI assistant and a frustrating one is almost entirely in the preset configuration.

This skill codifies the process of building high-quality presets: defining the persona and constraints, writing few-shot examples, specifying output formats, selecting appropriate model parameters (temperature, top-p, max tokens), and validating against a benchmark of expected inputs and outputs. Presets are version-controlled and A/B tested before deployment.

Use When

  • Creating domain-specific AI assistants (legal, medical, finance, code review)
  • Standardizing AI behavior across a team or organization
  • Building a library of reusable assistant configurations
  • Optimizing system prompts for specific use cases
  • A/B testing different assistant configurations
  • The user asks for a "custom assistant", "persona", or "system prompt"

assistant-presets is a skill published in the GitHub repository itallstartedwithaidea/agent-skills (37 stars, last pushed 4mo ago), licensed MIT. It adds 26 tokens to every session and 1,499 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
