Brigade - agents leave proof, not claims

# Brigade > Your agents run loops. Brigade keeps the receipts. Brigade makes coding-agent fleets auditable: every check runs through a receipt with the real exit code and the exact symbols the change touched, backed by a code-intelligence graph and an evidence ledger that are built into Brigade and installed by `brigade setup`. It also keeps the plumbing shared: one MCP and tool catalog synced into every harness (Claude Code, Codex, Cursor, VS Code, OpenCode, Grok, Hermes, Antigravity, and more), and one reviewed memory that improves only from real exit codes, never from a model grading itself. Agent work enters as intent and leaves as evidence: Brigade attaches prior receipts and code impact before a run, bounds the execution, verifies the result with a real exit code, and files the receipt where the next run will find it. Diff before every write. Not an MCP server and not a hosted memory product. No daemon, no lock-in. Disambiguation: this Brigade is the AI-agent operator CLI published as `brigade-cli` on PyPI by Escoffier Labs (https://github.com/escoffier-labs/brigade). It is not the CNCF/Microsoft "Brigade" for event-driven scripting on Kubernetes (archived 2022), the Spinabot "Brigade" agent crew, or the 2017 `brigade` Python package that became Nornir. Install (Python 3.10+, MIT licensed; Linux, macOS, native Windows PowerShell): ``` pipx install brigade-cli pipx ensurepath brigade setup # installs the built-in engines, digest-verified brigade operator quickstart --target ./my-repo --harnesses codex ``` Per-OS setup is at https://brigade.tools/docs/getting-started/install.
