Sirno ships an agent skill set that renders this lake's method into operational procedure.

There are five skills.
The editor skill creates, revises, and reorganizes entries, and moves design knowledge from a
monograph into the lake.
The explorer skill reads a Sirno-managed repository from the lake outward to locate design and its
evidence.
The witness skill links lake entries to repository evidence and keeps that evidence precise.
The narrative-session skill conducts an adaptive route through lake knowledge and materializes it
as a narrative entry.
The skill-synthesizer skill rebuilds the packaged skills from the lake's `meta`-categorized entries,
so the skill set stays a reproducible surface of the method rather than prose that can drift.

This entry is the review front door for those skills.
The durable procedure each skill encodes lives in its own discipline entry,
so a skill can be rebuilt from the lake rather than only from its packaged prose.
See `lake-editing-discipline`, `lake-exploration-discipline`, `witness-linking-discipline`,
`narrative-session-discipline`, and `skill-synthesis-discipline`.

The skills hand off rather than overlap.
Exploration switches to the witness skill when the task changes from reading evidence to creating
or refining it.
Exploration switches to the editor skill when the task changes from reading entries to editing them.
The editor skill defers to the repository documentation-writing skills for `README`, `DESIGN`,
and `METHODOLOGY` prose, because those documents have their own roles and style.

A skill is an operational rendering of lake method, not a separate authority.
When a skill and the lake disagree, the lake and `Sirno.toml` win,
and the skill should be corrected.
This keeps the lake the source of truth and the skills its reproducible surface.
