It became generally available with Claude 4 on 22 May 2025 and is one of the products that moved coding assistants from autocomplete to delegated engineering work.","full_description":"Claude 3.7 Sonnet was announced as a hybrid reasoning model with particular strength in coding. The same post introduced Claude Code as a limited research preview: an active collaborator that can search and edit code, write and run tests, and push to GitHub from the terminal. Anthropic said early internal use completed some tasks in a single pass that would normally take 45+ minutes. General availability on 22 May 2025 added IDE integrations and GitHub Actions background tasks. Independent measured productivity remains thin relative to Copilot’s 2022 RCT, so this is scored as a major product/feature launch that changed engineering practice, not as a proven output shock.","ledger_type":"benefit","primary_domain_id":"056250cf-05f4-4116-957c-78323ed7f8cf","event_status":"provisional","event_date":"2025-02-24T00:00:00.000Z","discovery_date":"2025-02-24T00:00:00.000Z","first_published_date":"2025-02-24T00:00:00.000Z","last_reviewed_date":"2025-02-24T00:00:00.000Z","geographic_scope":"International","affected_population":"Software engineers using Claude Code","base_impact_tier":3,"base_score":"10.00","attribution_multiplier":"0.7000","evidence_multiplier":"0.4000","realization_multiplier":"0.7500","durability_multiplier":"0.6500","current_event_score":"1.365000","confidence_level":"medium","score_explanation":"Agentic coding in the terminal is a major change in how software is written (tier 3).
