Changelog

Latest version = 0.19.0

0.19.0

This release includes breaking changes that require migration for existing projects.**

To migrate your existing projects using TESSL.md, run the following steps:

Adopted AGENTS.md standard (replacing TESSL.md) for unified AI agent configuration across your development workflow.
Improved Dependency Handling
- verify-deps now runs automatically after code generation in the build process.
- New specifyMissingDependencies flag can auto-update your spec with missing dependencies in tessl build and tessl edit.
- New never option added to generation mode to skip file generation entirely.
tessl status enhancements:
- Highlights whether a spec includes @generate or @describe annotations.
- Added dirtiness diagnostic to detect out-of-sync code/test files.
- Added diagnostic for missing AGENTS.md entries in tessl status.
Improved Spec & Test Management
- Rewritten document tool with more intuitive behavior and support for complex specs.
- Re-initializing a project now regenerates framework files.

Removes setup language command; tools that require test commands now have a --test-command flag.
Removed description upon tool invocation.
Increased latest version check timeout in update command to reduce false negatives.

Logging in from an agent now automatically updates the MCP server so you can continue without restarting.
Fixed tool summaries not showing in CLI output.
CLI session data no longer prevents process exit after command completion.

build tool now has a post-generation fix loop to automatically resolve issues - we will be tweaking how we decide which test command to run in the coming week
New status checks for orphaned tests, mixed implementation links & missing required files
Added support for agent-native planning: agents now create and maintain .plan.md files automatically during planning.

Removed --recursive option from status command for consistency with other commands
Replaced --rebuild-tests with --generate-tests to build to generate only missing, outdated or always (default is now outdated rather than missing)
Added --generate-code to build which behaves like --generate-tests but for code files (default is outdated, but is likely to change)
Generated code now includes self-hashing for integrity checking and better status reporting on modified files
Removed timestamps from generated code tags
Improved logging and error messages across tools
Improved exception messages to include more debugging context
Better editor detection and logging in planning workflows
Clarified descriptions for several commands & tools
Tools invoked via MCP now return more information about their run, improving feedback visibility for agents
The build tool now returns a failure exit code when the fix loop fails, ensuring accurate signaling of build status.

Removed ability to edit plan files directly via the edit tool; users now receive a clear error if they attempt to do so.
Made the plan tool private to reduce confusion and encourage agent-driven planning workflows

Fixes creation of the Claude subagent instructions directory as part of setup agent

Enabled tessl status to list all specs by default, providing broader project insights.
Updated tessl status to include sync checks that detect whether a spec's code and tests are up to date.

Updated build and document tool descriptions for clarity and accuracy.
Made the -spec parameter more explicit and consistently required in tessl status help output.
Renamed build tool's iterations parameter to maxIterations for clarity.
Renamed @build links to @generate to reflect intended behavior.

Fixed bash execution in the update command to work reliably across Mac and Linux.
Corrected error handling for expired keys.
Made terms and conditions check respect a global directory set via environment variable.
Fixed a crash in tessl status when a non-existent or empty spec file is provided.
Resolved incorrect logging of issue counts in single-spec status output.
Improved handling of file paths in the document tool to normalize inputs like ./path/to/file.
