No known findings in this image at the last scan.

These are the findings of lua, which ships every tool in this project. kapsl reports and gates; it never edits an image to clear a finding.

Composition

default + env, bash
runtime none — self-contained
composes env, bash

Some tools are only useful composed: a pip-installed CLI needs python as its runtime, bash pulls in coreutils. kapsl resolves that for you — -e git,python:flake8 composes explicitly.

Sandbox boundary

lua

capabilities

rw

Filled is granted to every invocation; the rest need --cap at the point of use.

seccomp tier

per tool

default

The syscall filter applied to this tool's entry point. Tools sharing an image do not share a tier.

dotfiles mapped in

read-only unless noted

  • ~/.inputrc

env passed through

3 forwarded

LUA_INITLUA_INIT_5_4LUA_INIT_5_5

Nothing else crosses in. No AWS_*, no SSH_AUTH_SOCK unless you ask.

env set by kapsl

4 set

CPLUS_INCLUDE_PATHC_INCLUDE_PATHLIBRARY_PATHPKG_CONFIG_PATH

per-subcommand

no overrides

Every invocation gets the same boundary. Where a tool needs more for one subcommand only, kapsl scopes it there rather than granting it everywhere.

Filled is granted to every invocation, outlined to some and not others — see per-subcommand below; the rest need --cap at the point of use.

Where a tool needs more for one subcommand only, kapsl scopes it there rather than granting it everywhere. Where it needs less, kapsl takes it away there too.
