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

Composition

default nothing — stands alone
runtime none — self-contained
composes not used as a runtime

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

file

capabilities

ro

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

none

env passed through

none

none

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

env set by kapsl

1 set

MAGIC

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.

Provenance

Every image ships a full SBOM and a signed build attestation. Nothing here is a claim you have to take on trust.

0 findings across this project at latest. Counted once per advisory across every image the project builds.
