For agents

An agent that drives rietx reads the rietx skill, a protocol and a set of reference files in the agentskills.io format.

The protocol says what to free in what order, what to check before believing a number, and which numbers may be quoted. An agent reads it whole before its first fit. The reference files are lookups it loads when a task needs one, such as the API index, the diagnostic codes or a series of patterns. Calling rietx from a program gives the Python surface the skill drives: the exceptions, the answer types, an answer’s JSON form and capabilities().

Installing the skill

The package carries the skill. This command installs it into the current project:

$ rietx skill --install .

The copy goes in .agents/skills/rietx/, which several harnesses read, and a link goes in each requested harness’s own directory. The command prints both paths, then two lines to add to the project’s AGENTS.md or CLAUDE.md. It does not write those lines itself. --agent NAME adds a harness, and rietx skill --list-agents lists the ones it knows. --user installs for your user account instead of one project.

Reading the skill without installing it

rietx skill --print prints the protocol, and rietx skill --print all prints every file. The same files are published at rietx.org/skill/rietx/SKILL.md, one file at a time, for a harness that has network access and no install.
