gmail-ai-broker: Instructions file for Claude Code

CLAUDE.md

gmail-ai-broker CLAUDE.md is an instructions file for Claude Code from InfiniteRoomLabs/gmail-ai-broker. It costs 1,254 tokens per session, scanned A, original, MIT.

A set of instructions for developing and maintaining a small Gmail automation command-line tool. It describes the tool's email features, security model, commands, architecture, and tests.

In plain words
What is it for?
It is for setting up dependencies, running tests and type checks, understanding the separation between email logic and network code, and extending attachment, sending, filter, or raw-message features.
Why use it?
It helps coding agents preserve the tool's safety and auditability while changing code that handles email and OAuth access.

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

gmail-ai-broker CLAUDE.md scanned grade A with 0 findings 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 9d 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.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How it starts

The opening of the file, as written. The whole thing — 97 lines — stays where its author put it; the contents beside it link to each section on GitHub.

CLAUDE.md

This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.

What This Is

A small, auditable Python CLI (gmail-ai-broker) that fills the four gaps the official claude.ai Gmail connector leaves open: attachment download, raw-MIME send with attachments, filter CRUD, and raw message fetch. Keep the official connector for reads/triage; this tool adds only the missing writes. The whole point is that it stays small enough to read end-to-end -- that auditability is the trust model. Read README.md for the full security model and one-time OAuth setup runbook.

Commands

uv sync                       # runtime deps
uv sync --extra dev           # + pytest, pytest-mock
uv run gmail-ai-broker --help
uv run --extra dev pytest -q              # full suite
uv run --extra dev pytest tests/test_mime.py -q          # single file
uv run --extra dev pytest tests/test_mime.py::test_name  # single test
uv run pyright                # type check (configured against the venv)

Always use uv -- never bare pip/python (see global instructions).

Architecture

The codebase splits into pure logic (unit-tested) and network glue (exercised live at "Gate 1", not mocked in unit tests). Preserve this split: new behavior with real logic goes in a pure module with tests; only the thin discovery/credential wiring stays untested.

Module Role Purity
mime.py raw MIME build (attachments) + attachment decode pure
models.py declarative FilterSpec -> Gmail filter resource (pydantic) pure
audit.py append-only JSONL mutation log pure
config.py TOML config load + XDG path defaults pure
auth.py token load/save (mode 600), credential build, loopback flow glue
service.py googleapiclient discovery build glue
client.py GmailBroker: the four capabilities wired together glue
cli/main.py typer entrypoint (auth/attachment/message/draft/filter groups) glue

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.
