relux:effect-edit
Modify an existing `effect` declaration -- changing its `expect` set, `expose` surface, `start <Dep>` graph, `let` / shell body, or cleanup -- with discipline about identity dedup deltas, caller-surface breakage, wrapper transparency, and verification rhythm. Use when the user asks to change an effect's body, add or remove an `expect` var, rename or drop an `expose`d shell or var, wire in a new dep, switch which shell is the service-running one, retune fail patterns, or split a bundled effect into Config+Service / layer chain. Fires on phrasings like "add a port to `Postgres`", "expose the service shell on `Db`", "drop `migrations_path` from `Database`", "split this effect's config rendering out", "the cleanup is wrong, it deletes the artifact". Authoring new effects is `relux:effect-write`; moving an effect between files or removing it are mechanical operations (grep + relocate / grep + delete callers) and have no skill of their own.

From the source SKILL.md
Edit an effect declaration in place. The discipline covers what breaks at each of the five mutation dimensions -- expect, expose, start <Dep>, let / shell body, cleanup -- and when those breaks become caller-visible (surface) or instance-visible (identity).
What this skill does
relux:effect-edit is a community-contributed Claude Code skill in the tools-misc sub-category. It ships as a SKILL.md file that Claude Code auto-discovers under ~/.claude/skills/effect-edit/ and loads when your prompt matches the skill's trigger.
When to invoke it: Use when the user asks to change an effect's body, add or remove an `expect` var, rename or drop an `expose`d shell or var, wire in a new dep, switch which shell is the service-running one, retune fail patterns, or split a bundled effect into Config+Service / layer chain. Fires on phrasings like "add a port to `Postgres`", "expose the service shell on `Db`", "drop `migrations_path` from `Database`", "split this effect's config rendering out", "the cleanup is wrong, it deletes the artifact".
