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

agent-builder 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 12d 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.

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

Agent Builder Skill

Metadata

  • Name: agent-builder
  • Trigger: Auto-triggered when building AI agents with DAPR
  • Category: AI Agent Development

Description

Provides intelligent assistance for building AI agents with the DAPR Agents framework. Validates configuration, suggests patterns, and ensures best practices.

Auto-Trigger Patterns

This skill activates when detecting:

  • Creation of agent files (*_agent.py, *agent*.py)
  • Import of dapr_agents or dapr-agents
  • Agent configuration files
  • Tool definitions with @tool decorator
  • Workflow-backed agent patterns

Capabilities

1. Agent Configuration Validation

Validates agent setup:

  • Required imports present
  • Agent name and role defined
  • Instructions are comprehensive
  • Model configuration is valid
  • Tools are properly decorated

2. Pattern Recommendations

Suggests appropriate patterns based on use case:

  • AssistantAgent: Basic interactive agents
  • DurableAgent: Fault-tolerant long-running tasks
  • AgentService: Headless REST API agents
  • Multi-Agent: Complex orchestration

3. Tool Integration Check

Validates tool definitions:

  • @tool decorator present
  • Docstrings for LLM understanding
  • Pydantic input validation
  • Async for I/O operations
  • Error handling

4. Memory Strategy Guidance

Recommends memory configuration:

  • Short-term (conversation context)
  • Long-term (DAPR state store)
  • Vector memory (RAG scenarios)

5. LLM Configuration Check

Validates LLM setup:

  • API key environment variables
  • Model name configuration
  • Temperature settings
  • Token limits

Validation Rules

Agent Definition

# Required elements:
from dapr_agents import AssistantAgent

agent = AssistantAgent(
    name="...",           # Required: unique identifier
    role="...",           # Required: agent's role
    instructions="...",   # Required: system prompt
    tools=[...],          # Optional: list of tools
    model="...",          # Optional: LLM model (default: gpt-4o)
)

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.

agent-builder is a skill published in the GitHub repository Sahib-Sawhney-WH/sahibs-claude-plugin-marketplace (4 stars, last pushed 8mo ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 1,680 tokens. A static security scan graded it A with 1 finding (makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
