# op-approach — assess approach before tackling
Big work fails when it starts in the wrong shape. An audit run as audit-and-apply produces incoherent findings. A refactor that smuggles in feature work bloats the diff and breaks both. A migration without a cutover plan leaves orphan data. A spike that quietly becomes production decays for years. All the same family — **work-shape-blindness**.
This skill is the meta-step *before* planning. Identify the shape, name the phases, name the traps. Then `op-prepare` runs the planning walk informed by the shape.
## When to fire
- User uses any of the trigger phrases listed in the `description:` above.
- User describes work that touches **>1 surface across >1 session**, or names a multi-domain change.
- Before `op-prepare` runs, for any work that isn't obviously a single-feature build.
- Whenever the user signals scale — *"the project has grown"*, *"step by step over multiple sessions"*, *"a big project"*.
## When NOT to fire
- One-line edits or single-file feature work — overhead exceeds payoff.
- A simple "I want to build X" where X is small and clearly build-shaped — `op-prepare` directly is fine.
- The work has already been shape-assessed in this conversation and the user is now executing — don't re-fire.
- Mid-session, when the user is in flow on Stage 3 Build — defer until the section is done.
## What to do
A short walk — six steps, kept tight. Output is a 5–6 line approach assessment, not a document.
