What this skill does

Fathom Local Dev Loop Overview Use Fathom integrations in the normal local development loop: narrow change, synthetic validation, review, focused tests, and reversible commit. Prerequisites A clean or recoverable branch, development credential, synthetic meeting/CRM fixtures, repository rules, and test commands. Instructions 1. Make one scoped integration/configuration change using development-only data and identity. 2. Inspect the diff, run focused mock/unit checks, and execute a bounded synthetic workflow test. 3. Commit reviewed changes separately and promote only through normal protected workflow. Output A small reviewed change with test evidence and a normal rollback path, without production meeting or contact data. Error Handling Condition Safe response --- --- Synthetic test exposes real data Stop, restrict access, and follow the data procedure. CRM mapping/test fails Revert or correct within scope; do not use production records to diagnose. Working tree is mixed Separate unrelated changes before committing. Examples Update one mapping using a synthetic meeting/action, run its focused test, inspect the redacted result, and commit it separately. If the test fails or unrelated files change, revert/split the work rather than disabling checks or pointing local tooling at production.
