Edit

Change a skill that exists, built by Smithy or not. Its outcome: the change the user asked for, applied to the canon's standard, with nothing else disturbed.

Read

Set {target} to the skill folder. Read SKILL.md and only the files the change touches; the rest stays unread so it stays unchanged.

Agree the change

One read-back, then wait: what changes, what stays, whether the shape changes (a menu added to a plain skill, memory added to an agent), whether the description changes. A description change is a trigger change; say so.

Rebuild instead

When the user wants to rethink the skill from its outcomes rather than adjust it, that is a build: say so and load discover.md with the old skill as the mined input. Its files are reference material, not the starting point.

Apply

Make the change to canon.md and cut any line the change makes dead. Fit the existing voice and structure, so a reader sees no seam. When the change touches the description or adds a capability, write or extend {target}/evals/triggers.json with queries for the new ground and near misses beside it, so ship's trigger eval covers what changed. For a rendered skill, edit the sources (workflow.md, step-*.md, customize.toml), never the rendered snapshot. For an agent, a new capability is a references/<capability>.md or a named skill, added to the menu.

Then

Load ship.md.
