Simply giving an AI agent thousands of tools is counterproductive. The real value lies in an 'agentic tool execution layer' that provides just-in-time discovery and managed execution to prevent the agent from getting overwhelmed by its options.
The debate over whether CLI or MCP is better for AI agents is a false dichotomy. Both will coexist. The interface that attracts more token expenditure will likely improve faster due to reinforcement learning, but neither will fully displace the other.
Composio uses an internal agent pipeline to build and test its tool integrations. When a tool fails in production for any reason, this pipeline is invoked in real-time to create and swap in a newer, improved version, creating a self-healing system.
The most impactful AI agent applications are moving beyond simple automation. Composio's CTO uses an agent to perform the full role of a technical recruiter, from sourcing candidates on GitHub to drafting and sending initial outreach emails.
For high-volume tasks like processing thousands of emails, standard function calling fails due to context limits. The solution is a sandboxed environment where an agent writes and executes code to programmatically call tools, enabling large-scale data processing.
The AI wave won't necessarily kill major SaaS players like Salesforce. Instead, the competitive battleground is shifting to who can build the best new agentic interface for their existing platform. Incumbents are adapting quickly, challenging AI-native startups.
While AI models have different behaviors, their core strength is instruction following. By creating thorough 'skills,' developers can achieve consistent outputs from different frontier models, effectively commoditizing the underlying model and reducing vendor lock-in.
An effective cost-saving strategy for agentic workflows is to use a powerful model like Claude Opus to perform a complex task once and generate a detailed 'skill.' This skill can then be reliably executed by a much cheaper and faster model like Sonnet for subsequent use.
A key behavioral difference between frontier models is how they handle tasks requiring waiting. Anthropic's models tend to autonomously write code to wait and check for results, while GPT models often halt and require user input, a crucial distinction for agent reliability.
While building a custom support agent might be cheaper than using a service like Intercom's Fin, the primary advantage is customizability. Building your own allows for creating highly specific skills and integrating a wider range of tools to make the agent more powerful.
The team managing Composio's AI pipeline for building tool integrations spends more on LLM tokens than on salaries for its engineers. This signals a new economic reality for AI-native companies where compute is a larger operational cost than labor.
