Module probes 

The environment probe catalog.

One catalog, read by every caller that needs to know whether this host is ready: rk doctor runs it whole, and a mutating command guards the subset it depends on at entry, so the per-command guards and the doctor cannot drift apart. Each probe answers with a status, a message, and — on failure — the remediation printed verbatim wherever the probe is consulted.

Structs

ProbeResult

One probe’s answer.

Enums

ProbeClass

How a failure weighs at the doctor level.

ProbeStatus

What a probe found.

Constants

HARD_RUNTIME_TOOLS

Every executable a Hard probe requires, paired with the nixpkgs package whose bin/ supplies it in the installed package’s wrapper.

SKILL_PROBES

The probes judging the skill installation itself, in catalog order.

Functions

direnv

direnv answers; it loads the devshell on directory entry.

direnv_bin

One owner for the direnv binary, which nothing here spawns but the doctor probes: it is what loads a consumer’s devshell on entry. RK_DIRENV_BIN substitutes it.

git_bin

One owner for the git binary every production launcher spawns.

nix

Nix answers; rk devshell sync updates and builds the pinned devshell with it. Soft, and deliberately outside the wrapper: wrapping nix would put it inside the package’s own closure on every host.

nix_bin

One owner for the nix binary every devshell launch spawns: the lock refresh, the system probe, and the build. RK_NIX_BIN substitutes it.

run_all

Run the whole catalog, in its stable order.

sh_bin

One owner for the POSIX shell every setup step spawns through.
