agent-redact (Python)

Python bindings for agent-redact. This is a thin, dependency-free wrapper around the Node.js CLI, so Python agents get exactly the same detection engine as the npm package.

pip install agent-redact

Node.js 20+ is still required. This package contains only the Python wrapper; the detection engine is the Node.js CLI (see below for how it is found).

Requirements:

• Python 3.10+
• Node.js 20+
• the CLI, from one of these (checked in order):
  1. AGENT_REDACT_CLI set to the absolute path of dist/cli/index.js;
  2. a global npm install -g agent-redact;
  3. npm next to node: the matching version is installed once into a private user cache (--ignore-scripts) and reused.

The CLI is always started as node <absolute path>. It is never run through .cmd/.bat shims, through npx, or from a binary found in the current directory, so scanning an untrusted repository cannot hijack it.

from agent_redact import redact, scan, Session

# One-way redaction
result = redact("deploy with AKIA...")       # result.text, result.matches (no secret values)
redact(text, presets=["vn-pii"])             # opt-in presets

# Reversible masking across a whole conversation
with Session() as s:
    safe_prompt = s.redact(user_prompt)      # [AWS_ACCESS_KEY_ID_1] …
    answer = llm(safe_prompt)
    print(s.unmask(answer))                  # placeholders restored locally

# Repository / staged-changes audit
findings = scan(["."])                       # honours .gitignore in git repos
findings = scan(staged=True)                 # what is about to be committed

Session keeps its vault in a private temporary directory, encrypted with a random per-session passphrase that is never written to disk, and deletes it on close() or when the with block ends.
