How to Use Air for Diff review before commit
Learn Air diff review before commit with step by step workflows, realistic examples, and verified plan notes.
Air works well for diff review before commit when you run it like production work: locked brief, SOURCE facts, then review before publish. Air is JetBrains Agentic Development Environment for parallel coding agents with Docker or Git worktree isolation. Requires JetBrains AI Pro/Ultimate or BYOK. Confirm task definition and review workflows in JetBrains Air docs. Start at /explore/air.
This guide focuses on diff review before commit in detail. Related Air articles: /blog/how-to-use-air-for-multi-file-feature-implementation, /blog/how-to-use-air-for-documentation-and-readme-updates, /blog/how-to-use-air-for-parallel-agent-tasks-in-worktrees.
When this workflow is the right job
Use diff review before commit when the deliverable is specifically this Air job. Switch to parallel agent tasks in worktrees when that workflow already owns the asset.
Step by step workflow
1. Brief Diff review before commit
Write what must stay true for diff review before commit in Air before settings or spend.
Brief: Diff review before commit Keep: verified SOURCE facts only Avoid: invented pricing or features Success: one reviewable output
2. Open Air for Diff review before commit
Use the Air surface that owns diff review before commit. Do not mix a neighboring workflow in the same pass.
Surface: Diff review before commit Start: pilot with one representative input Plans: air.dev
3. Pilot Diff review before commit
Run a single diff review before commit pilot. Score clarity, grounding, and whether the output is reviewable.
Pilot: Diff review before commit [ ] SOURCE facts match [ ] Output reviewable [ ] Settings logged
4. Refine Diff review before commit
Change one diff review before commit dimension only. Save a template from the best run.
Refine: Diff review before commit Change: one control only Keep: SOURCE and success criteria

How to improve diff review before commit
Cut noise from diff review before commit by removing extra adjectives while preserving SOURCE facts in Air.
Raise quality by insisting on a single success check before debating style.
Make review easier by labeling fields that must never change.
Speed iteration by cloning the last good run and altering only one control.
Stabilize outputs by pinning settings after the pilot is approved.
Reduce rework by rejecting drafts that invent claims.
Improve handoffs by recording which control produced the best result.
Harden the workflow by testing an incomplete input before trusting defaults.
Prompting and usage guidance
Name the diff review before commit job, audience, and success check before opening Air.
Paste only verified facts under SOURCE so Air cannot invent details.
Specify the deliverable shape up front.
Call out fixed details versus flexible style choices.
Ask Air to flag unsupported claims before you accept the draft.
Limitations to respect
Check Air plan gates for diff review before commit on air.dev before you promise timelines.
Keep drafts unpublished until a human confirms SOURCE facts.
Air can be wrong. Treat diff review before commit as provisional until review.
If documentation is silent on a claim, leave it out rather than guessing.
Practical tips for this workflow
Pilot once before batching diff review before commit in Air.
Keep a reusable template with variables for diff review before commit.
Separate creative instructions from SOURCE facts.
Log settings from the best run.
Common mistakes
- Skipping the pilot run before scaling volume
- Inventing pricing, quotas, or features not on official pages
- Mixing unrelated workflows in one session
- Publishing without a human review gate
Treat diff review before commit in Air as a production workflow: brief, pilot, refine, then ship with review.
