sluice

An outbound egress guard for agents — scan any message (email, social draft, Telegram reply, a write to a public site) for leaked secrets and private identifiers before it goes out, and either refuse it or redact them in place. Pure standard library, precision-tuned to not cry wolf.

Agents touch live credentials all day: API keys in .env, bot tokens in systemd units, JWTs from Supabase. One careless paste into outbound copy and a key is on the public internet forever. sluice is the gate between the machine's insides and the outside world: every outbound message passes through it first. Pure Python standard library — no network, no model call, no dependencies.

The executable is {baseDir}/bin/sluice.

When to use this

Put sluice in front of anything an agent sends or publishes — an email, a social post, a Telegram reply, a commit to a public site. Use scan as a pre-send gate (blocks on a breach) or redact to scrub in a pipe.

How to use it

text

# gate a draft — only proceeds if clean (scan exits non-zero on a breach)
{baseDir}/bin/sluice scan draft.md && ./send-it draft.md

# scrub a file and keep going
{baseDir}/bin/sluice redact draft.md > safe.md

# sits in a pipe
generate-post | {baseDir}/bin/sluice redact | queue-to-typefully

# machine-readable, control the block threshold
{baseDir}/bin/sluice scan --json --fail-on high draft.md

scan prints findings to stderr and exits non-zero at or above --fail-on (default high). redact writes cleaned text to stdout. Previews never echo the full secret — glpa…z9 (26 chars), never the value.

What it catches

• High (live credentials, block by default): Anthropic / OpenAI / OpenRouter keys, GitLab & GitHub PATs, AWS access keys, Slack tokens, Stripe live keys, Telegram bot tokens, JWTs / Supabase keys, PEM private-key blocks.
• Medium: key = <high-entropy value> assignments (entropy-gated so prose doesn't trip it), private infrastructure paths.
• Low: RFC1918 private IPs (topology leak).

Notes for the agent

• Reference the tool as {baseDir}/bin/sluice — never hardcode a path.
• High-severity detectors are tuned for precision (a guard that cries wolf gets switched off); the generic key=value rule carries a Shannon-entropy gate.
• Extend by adding a Detector to sluice/detectors.py.
