Landing page: https://mukundakatta.github.io/agent-stack/ Paper: Six Reliability Primitives for LLM Agents: An Artifact Pattern for Stackable, Single-Concern Libraries HuggingFace Hub: mukunda1729/agent-stack

The six primitives

| Library | Concern | | --- | --- | | AgentFit | Token-aware context-window fitting | | AgentGuard | Network egress allowlist for tool calls | | AgentSnap | Snapshot tests for tool-call traces | | AgentVet | Tool-arg validation with retry hints | | AgentCast | Structured-output validate-and-retry for LLM JSON | | AgentBudget | Per-run token + dollar caps |

Each ships in three forms: TypeScript on npm, Python on PyPI, MCP-server variant.
