Summary

• add mise run --affected --affected-json for machine-readable project and task selection
• include stable revision, project-root, reason, and task-to-project fields
• exit before dependency expansion, tool installation, or task execution
• document the schema and mark the affected-output tracker item complete

Validation

• mise run lint
• cargo clippy --workspace --all-features --all-targets -- -D warnings
• mise run test:e2e e2e/tasks/test_task_affected
• mise run render

Note

Low Risk
Additive CLI and output path on existing experimental affected selection; early exit avoids side effects and is covered by e2e.

Overview
Adds --affected-json to mise run (with --affected) so CI and other tools can get the same pre-expansion selection as --affected-explain, but as stable pretty-printed JSON. The payload includes base/head, affected projects (id, root, reasons), and matched tasks (name, projects).

When JSON mode is on, the run path returns immediately after emitting output—no dependency expansion, tool install, or task execution. --affected-json and --affected-explain are mutually exclusive. Call sites that construct Run (bootstrap, shorthand task routing) pass affected_json: false.

Docs, usage spec, man pages, monorepo guide, the task-cache parity tracker, and an e2e assert_json check cover the flag and schema.

Greptile Summary

Adds machine-readable affected-project and affected-task selection to mise run, returning before dependency expansion, tool installation, or execution.

• Introduces the mutually exclusive --affected-json output mode.
• Serializes revisions, affected projects and reasons, and task-to-project associations.
• Updates generated CLI documentation, monorepo documentation, and end-to-end coverage.

Confidence Score: 5/5

The PR appears safe to merge.

No blocking failure remains within the eligible follow-up review scope.
