[ 09 Key Takeaways ](#key-takeaways) Laravel Boost v2.6.0 Is Out --------------------------- Laravel Boost v2.6.0 landed on August 26, 2026, with three headline changes: a consolidated `testing-best-practices` skill for AI coding agents, database-enforced read-only transactions for the `DatabaseQuery` MCP tool, and a round of skill management fixes. --- Unified Testing Best Practices Skill ------------------------------------ Previous versions of Boost shipped several overlapping testing skills — `pest-testing`, `enforce-testing`, and `phpunit-guidelines`. When AI agents had access to all three simultaneously, the results were inconsistent: duplicate mocks, conflicting conventions, and tests that poked at framework internals rather than application behaviour. v2.6.0 replaces them with a single `testing-best-practices` skill. Boost composes the skill dynamically based on the testing packages present in your project, so it adapts automatically to Pest, PHPUnit, browser testing, and Test Impact Analysis. The consolidated skill covers nine areas: - **Assertions** — prefer semantic helpers like `assertOk()` over raw status-code checks - **Endpoint Tests** — focus HTTP tests on authorization and core responses, not validation matrices - **Feature Discovery** — locate existing tests before writing new ones - **Isolation** — prevent shared state leaks; scope database transactions to relevant tests - **Naming** — use names that describe expected behaviour - **Performance** — avoid creating unnecessary database records in setup hooks - **Review** — audit suites and prune duplicate coverage - **Security** — test hostile inputs and unauthenticated boundaries - **Test Data** — use focused model factories instead of bloated datasets --- Database-Enforced Read-Only Transactions ---------------------------------------- The `DatabaseQuery` MCP tool previously relied on lexical keyword filtering to block write operations. Keyword checks catch obvious `INSERT` or `UPDATE` statements, but they miss more complex SQL shapes such as data-modifying common table expressions (CTEs). v2.6.0 wraps every query in a database-enforced read-only transaction: ```sql -- MySQL / MariaDB SET TRANSACTION READ ONLY; START TRANSACTION; -- ... your query ... ROLLBACK; -- PostgreSQL START TRANSACTION; SET TRANSACTION READ ONLY; -- ... your query ... ROLLBACK; ``` For SQLite, Boost sets `PRAGMA query_only = ON`. Regardless of dialect, the transaction is always rolled back after the query completes, so the database engine itself rejects any modification that slips past lexical parsing. --- Skill Management and Tooling Fixes ---------------------------------- ### Safe Skill Installation `boost:add-skill` now ignores repository-root `SKILL.md` files. Previously, the command could mistake a root-level file for a skill directory entry and delete the entire skills directory during installation. The command also accepts arbitrary skill path shapes. ### MySQL `ANSI_QUOTES` Support Schema reads now quote table types as string literals, so schema tools work correctly when MySQL runs in `ANSI_QUOTES` mode. ### MCP Server JSON Formatting Boost preserves trailing comments when writing MCP server configurations to JSON files, keeping hand-edited config files intact. ### Agent Detection Fix A false-positive Antigravity detection that fired when scanning the shared `.agents` directory has been resolved. --- Key Takeaways ------------- - The new `testing-best-practices` skill replaces three overlapping skills, giving AI agents a single, consistent source of testing guidance. - `DatabaseQuery` now uses native read-only transactions on MySQL, MariaDB, PostgreSQL, and SQLite — not just keyword filtering. - `boost:add-skill` is safer: it no longer risks deleting your skills directory when a root `SKILL.md` is present. - MySQL `ANSI_QUOTES` mode is now supported for schema reads. --- *Source: [Testing Best Practices Skill in Laravel Boost v2.6.0 — Laravel News](https://laravel-news.com/laravel-boost-2-6-0)* Found this useful?

It replaces three previously separate skills — pest-testing, enforce-testing, and phpunit-guidelines — which overlapped and caused AI agents to produce inconsistent test suites. The single consolidated skill is composed dynamically based on the testing packages installed in your project. Q02 Why did Laravel Boost switch from keyword filtering to database-enforced read-only transactions? Lexical keyword filtering can miss complex SQL constructs such as data-modifying CTEs. By wrapping queries in a native read-only transaction (SET TRANSACTION READ ONLY on MySQL/MariaDB, SET TRANSACTION READ ONLY on PostgreSQL, and PRAGMA query_only = ON on SQLite) and always rolling back, the database engine itself enforces the read-only constraint. Q03 What was the boost:add-skill bug fixed in v2.6.0? The command previously treated a repository-root SKILL.md file as a skill directory entry, which could cause it to delete the entire skills directory during installation. v2.6.0 makes the command ignore root-level SKILL.md files and also adds support for arbitrary skill path shapes.
