Augment review alternative with a direct requirement-check rate

Perch prices fresh semantic rule checks directly. Save an English requirement and let the coding agent run the selected method check after every relevant repair instead of budgeting a broader agent task.

perch check reads working files; perch scan reads Git HEAD. Relevant source is sent to TypeSafe’s hosted models. The MIT CLI does not run model inference offline.

Catch the fix an agent removes later.

A saved requirement makes a recurring mistake checkable. In this Perch capture from September 20, 2026, the same rule flags a missing guard and passes after the guard is restored.

The regression

def refund(order, payment):
    payment.refund(order.total)
    order.status = "refunded"
    return order

1 check, 1 broken. Refunded orders cannot be refunded again.

The guarded method

def refund(order, payment):
    if order.status == "refunded":
        return order
    payment.refund(order.total)
    order.status = "refunded"
    return order

1 check, nothing to report.

Augment review alternative with a direct requirement-check rate

Augment bundles coding and review in a flat subscription with metered usage. Choose Perch when you want a separately selectable semantic requirement with a direct fresh-check rate. The MIT CLI can run inside the agent's edit loop and in CI.

Review before committing

Augment Code Review: CLI access is included; GitHub AI review is a documented workflow. Augment Code Review workflow documentation.

Perch reads the current working file with perch check. For a known requirement, select its rule name and method instead of requesting another broad review. A local CLI describes where the command runs; Perch sends relevant source to hosted TypeSafe models for analysis.

How do saved requirements differ?

Augment Code Review: Project context guides review; precise custom-review rule limits were not verified. Augment Code Review rule documentation.

Perch stores English ensure rules in perch.yaml or .perch/rules/. Project, file and method scopes determine what is checked. Run the named check after an edit and after the repair; a rule finding can fail the command and a CI gate. Perch rules · Working-file checks.

What does the review bill depend on?

Compare Augment Code Review's billing unit and Perch's usage estimate

Is the CLI open source and offline?

Augment Code Review: Commercial coding and review service. Augment Code Review product or license source.

Perch’s CLI is MIT-licensed; hosted model inference is a separate paid service included in its published check rate. It does not run the model offline. Unchanged requests can reuse cached answers for free. Fresh judgments can vary, and a passing requirement check does not prove application correctness. Perch MIT license.

When does Augment Code Review fit the workflow?

Augment combines coding-agent access and GitHub review. Model cost, service fees, compute and top-ups can affect usage; the displayed subscription is not the guaranteed price of every review volume.

Make the agent check its next edit.

Save a behavior rule

perch rules add refund-once \
  --where refund.py --each method \
  --ensure "Refunded orders cannot be refunded again."

The captured rule checks the requirement shown above. Rule syntax and selectors

Use perch scan for repository code at Git HEAD and changed-code CI checks for pull requests. New model judgments can vary. Repeatability comes from cached answers for unchanged requests; a pass does not prove application correctness.

Keep your project requirements checkable.

Choose Perch when you want an MIT CLI, English behavior rules and usage pricing that stays independent of team size. Give your coding agent a saved check it can run after every relevant edit.
