 ### Features
 
+* **phpstan:** add PHP ecosystem module with JSON injection (`--error-format=json`); groups errors by file sorted by count, auto-detects `vendor/bin/phpstan`, text fallback for custom formats (75%+ token savings)
 * **aws:** expand CLI filters from 8 to 25 subcommands — CloudWatch Logs, CloudFormation events, Lambda, IAM, DynamoDB (with type unwrapping), ECS tasks, EC2 security groups, S3API objects, S3 sync/cp, EKS, SQS, Secrets Manager ([#885](https://github.com/rtk-ai/rtk/pull/885))
 * **aws:** add shared runner `run_aws_filtered()` eliminating per-handler boilerplate
 * **tee:** add `force_tee_hint()` — truncated output saves full data to file with recovery hint

+## Specifics
+
+- `phpstan_cmd.rs` — PHPStan static analysis with JSON injection (`--error-format=json`); groups errors by file, sorted by error count descending, shows up to 10 files × 5 messages each (75%+ reduction). Falls back to text parsing when the user specifies a custom format flag.
+  - Detects `vendor/bin/phpstan` automatically (Laravel/Composer projects)
+  - JSON path: injects `--error-format=json`, parses `totals` + `files` structure
+  - Text path: scans for `[OK]` / error count summary lines
+  - Fallback: `fallback_tail()` on JSON parse failure — never blocks execution
