Covers writing regression tests for previously found bugs (24 total), rebuilding the SQLite audit ledger using only Python's standard library to eliminate the aiosqlite dependency, catching an accidentally included ipykernel dependency before release, and resolving a PyPI name collision by publishing as agentarmour-toolkit while keeping import paths unchanged. The library ships with CI across Python 3.10–3.12, a CLI, a Streamlit dashboard, and eight pages of MkDocs documentation on GitHub Pages. Previews the next module, AgentBudget, for tracking token usage and cost per agent node. ## Full article daily.dev links to this article rather than hosting it.
